If I understand correctly, you want flex-2-child to fill the height and width of its parent, so that the red area is fully covered by the green?

If so, you just need to set flex-2 to use Flexbox:

.flex-2 {
    display: flex;
}

Then tell flex-2-child to become flexible:

.flex-2-child {
    flex: 1;
}

See http://jsfiddle.net/2ZDuE/10/

The reason is that flex-2-child is not a Flexbox item, but its parent is.

Maybe a little late to the party but why don't you use sessions to store your data?

bookingfacilities.php

session_start();
$_SESSION['form_date'] = $date;

successfulbooking.php

session_start();
$date = $_SESSION['form_date']; 

Nobody will see this.

Use

document.getElementById("file-id").files[0].name; 

instead of

document.getElementById('file-id').value

socket.send is implemented for compatibility with vanilla WebSocket interface. socket.emit is feature of Socket.IO only. They both do the same, but socket.emit is a bit more convenient in handling messages.

Suppose you have df with columns A B C.

The most simple way is:

df = df.reindex(['B','C','A'], axis=1)

There are many very feature rich and ingenious answers already. To provide some contrast, I could make do with a very simple line.

# Check return value to see if there are incoming updates.
if ! git diff --quiet remotes/origin/HEAD; then
 # pull or whatever you want to do
fi

The process is greatly simplified for VS2017 / VS2019 (maybe even earlier, but I have not tested) in conjunction with GitHub:

1. Create an empty repository in GitHub => https://github.com//.git

2. Install GitHub extension for Visual Studio

3. Follow these instructions: (optionally add to source control to git initialize) -> Team explorer -> Sync -> Publish to GitHub -> https://github.com//.git

Jquery One-liners:

ES6 + jQuery:

$('#select').append([...Array(100).keys()].map((i,j) => `< option >${i}</option >`))

Lodash + jQuery:

$('#select').append(_.range(100).map(function(i,j){ return $('<option>',{text:i})}))

Originally posted as an edit to @0x90's answer, but it got rejected for deviating from the post's original intent and recommended to post as a comment or answer, so I'm including the short write-up here.

In addition to the answer from @0x90, the syntax can be made more flexible, by using a variable for the width (as per @user2763554's comment):

width=10
'{0: <{width}}'.format('sss', width=width)

Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format:

width=10
'{0: <{1}}'.format('sss', width)

Or even leave out all numbers for maximal, potentially non-pythonically implicit, compactness:

width=10
'{: <{}}'.format('sss', width)

Update 2017-05-26

With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to access previously defined variables with a briefer syntax:

>>> name = "Fred"
>>> f"He said his name is {name}."
'He said his name is Fred.'

This also applies to string formatting

>>> width=10
>>> string = 'sss'
>>> f'{string: <{width}}'
'sss       '

Use this to obtain only the filename.

Path.GetFileName(files[0]);

Please, use for it ngChange directive. For example:

<select ng-model="blisterPackTemplateSelected" 
        ng-options="blisterPackTemplate as blisterPackTemplate.name for blisterPackTemplate in blisterPackTemplates" 
        ng-change="changeValue(blisterPackTemplateSelected)"/>

And pass your new model value in controller as a parameter:

ng-change="changeValue(blisterPackTemplateSelected)"

I had a situation, where I was suppose to get distinct elements from list based on 2 keys. If you want distinct based on two keys or may composite key, try this

class Person{
    int rollno;
    String name;
}
List<Person> personList;


Function<Person, List<Object>> compositeKey = personList->
        Arrays.<Object>asList(personList.getName(), personList.getRollno());

Map<Object, List<Person>> map = personList.stream().collect(Collectors.groupingBy(compositeKey, Collectors.toList()));

List<Object> duplicateEntrys = map.entrySet().stream()`enter code here`
        .filter(settingMap ->
                settingMap.getValue().size() > 1)
        .collect(Collectors.toList());

it doesn't work because you have not programmed a fail-safe into the code. java sees that the scanner can still collect input while there is input to be collected and if possible, while that is true, it keeps doing so. having a scanner test to see if a certain word, like EXIT for example, is fine, but you could also have it loop a certain number of times, like ten or so. but the most efficient approach is to ask the user of your program how many strings they wish to enter, and while the number of strings they enter is less than the number they put in, the program shall execute. an added option could be if they type EXIT, when they see they need less spaces than they put in and don't want to fill the next cells up with nothing but whitespace. and you could have the program ask if they want to enter more input, in case they realize they need to enter more data into the computer. the program would be quite simplistic to make, as well because there are a plethera of ways you could do it. feel free to ask me for these ways, i'm running out of room though. XD

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

To install GLIBC_2.14 or GLIBC_2.15, download package from /gnu/libc/ index at

https://ftp.gnu.org/gnu/libc/

Then follow instructions listed by Timo:

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz

2. cd glibc-2.14

3. mkdir build

4. cd build

5. ../configure --prefix=/opt/glibc-2.14

6. make

7. sudo make install

8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

To do this you need a JDBC Connection and/or driver that supports logging the sql at a low level.

Take a look at log4jdbc

if you use window.open(url, '_blank') , it will be blocked(popup blocker) on Chrome,Firefox etc

try this,

$('#myButton').click(function () {
    var redirectWindow = window.open('http://google.com', '_blank');
    redirectWindow.location;
});

All you have to do is assign this property:

img {
    display: block;
}

The images by default have this property:

img {
    display: inline;
}

You can press I twice to interrupt the kernel.

This only works if you're in Command mode. If not already enabled, press Esc to enable it.

I found another reason of this error. If you rooted your device access permissions of /data/local/tmp may be changed, so adb can't get access to it temp file. Solution is to create "tmp" folder on sdcard and create symlink to it in /data/local/ (via ADB shell or Root Explorer).

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

The style that you give the "g" element will apply the child elements, not the "g" element itself.

Add a rectangle element and position around the group you wish to style.

See: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/g

EDIT: updated wording and added fiddle in comments.

Let me give you a very plain Node.js style example of using a callback:

/**
 * Function expects these arguments: 
 * 2 numbers and a callback function(err, result)
 */
var myTest = function(arg1, arg2, callback) {
  if (typeof arg1 !== "number") {
    return callback('Arg 1 is not a number!', null); // Args: 1)Error, 2)No result
  }
  if (typeof arg2 !== "number") {
    return callback('Arg 2 is not a number!', null); // Args: 1)Error, 2)No result
  }
  if (arg1 === arg2) {
    // Do somethign complex here..
    callback(null, 'Actions ended, arg1 was equal to arg2'); // Args: 1)No error, 2)Result
  } else if (arg1 > arg2) {
    // Do somethign complex here..
    callback(null, 'Actions ended, arg1 was > from arg2'); // Args: 1)No error, 2)Result
  } else {
    // Do somethign else complex here..
    callback(null, 'Actions ended, arg1 was < from arg2'); // Args: 1)No error, 2)Result
  }
};


/**
 * Call it this way: 
 * Third argument is an anonymous function with 2 args for error and result
 */
myTest(3, 6, function(err, result) {
  var resultElement = document.getElementById("my_result");
  if (err) {
    resultElement.innerHTML = 'Error! ' + err;
    resultElement.style.color = "red";
    //throw err; // if you want
  } else {
    resultElement.innerHTML = 'Result: ' + result;
    resultElement.style.color = "green";
  }
});

and the HTML that will render the result:

<div id="my_result">
  Result will come here!
</div>

You can play with it here: https://jsfiddle.net/q8gnvcts/ - for example try to pass string instead of number: myTest('some string', 6, function(err, result).. and see the result.

I hope this example helps because it represents the very basic idea of callback functions.

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

You can even try below option:

<a href="javascript:show_more_menu();">More >>></a>

They remain in the fields because you are explicitly telling PHP to fill the form with the submitted data.

<input name="firstname" type="text" placeholder="First Name" required="required" 
value="<?php echo $_POST['firstname'];?>">
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ HERE

Just remove this, or if you want a condition to not do so make a if statement to that echo or just cleanup the $_POST fields.

$_POST = array(); // lets pretend nothing was posted

Or, if successful, redirect the user to another page:

header("Location: success.html");
exit; // Location header is set, pointless to send HTML, stop the script

Which by the way is the prefered method. If you keep the user in a page that was reached through a POST method, if he refreshes the page the form will be submitted again.

If your include directories are referenced correctly in the VC++ project property sheet -> Configuration Properties -> VC++ directories->Include directories.The path is referenced in the macro $(VC_IncludePath) In my VS 2015 this evaluates to : "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include"

using namespace std;
#include <iostream> 

That did it for me.

I would consider to refactor the service to return your domain object rather than JSON strings and let Spring handle the serialization (via the MappingJacksonHttpMessageConverter as you write). As of Spring 3.1, the implementation looks quite neat:

@RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE, 
    method = RequestMethod.GET
    value = "/foo/bar")
@ResponseBody
public Bar fooBar(){
    return myService.getBar();
}

Comments:

First, the <mvc:annotation-driven /> or the @EnableWebMvc must be added to your application config.

Next, the produces attribute of the @RequestMapping annotation is used to specify the content type of the response. Consequently, it should be set to MediaType.APPLICATION_JSON_VALUE (or "application/json").

Lastly, Jackson must be added so that any serialization and de-serialization between Java and JSON will be handled automatically by Spring (the Jackson dependency is detected by Spring and the MappingJacksonHttpMessageConverter will be under the hood).

ToTitleCase() should work for you.

How about:

public void printMB(uint sizekB)   
{
    double sizeMB = (double) sizekB / 1024;
    Console.WriteLine("Size is " + sizeMB.ToString("0.00") + "MB");
}

E.g. call like

printMB(123456);

Will result in output

"Size is 120,56 MB"

__str__ is only called when a string representation is required of an object.

For example str(uno), print "%s" % uno or print uno

However, there is another magic method called __repr__ this is the representation of an object. When you don't explicitly convert the object to a string, then the representation is used.

If you do this uno.neighbors.append([[str(due),4],[str(tri),5]]) it will do what you expect.

I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."

Calling a function/class instance in Python means invoking the __call__ method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__ method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".

As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...) is a shorthand for x.__call__(arg1, arg2, ...)".

Thus whenever you define a function with the shorthand def funcname(parameters): you are really just creating an object with a method __call__ and the shorthand for __call__ is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.

For now I suggest reading the Official Python Tutorial.

Eli, it is important to remember that in css specificity goes a long way. If your inline css is using the !important and isn't overriding the imported stylesheet rules then closely observe the code using a tool such as 'firebug' for firefox. It will show you the css being applied to your element. If there is a syntax error firebug will show you in the warning panel that it has thrown out the declaration.

Also remember that in general an id is more specific than a class is more specific than an element.

Hope that helps.

Make it a background image that is centered.

.wrapper {background:transparent url(yourimage.jpg) no-repeat center center;}

<div class="wrapper">
 ...input boxes and labels and submit button here
</div>

For Debian Jessie (which is the current default for the PHP image on Docker Hub):

apt-get install --yes zip unzip php-pclzip

You can omit the --yes, but it's useful when you're RUN-ing it in a Dockerfile.

The builtin SequenceMatcher is very slow on large input, here's how it can be done with diff-match-patch:

from diff_match_patch import diff_match_patch

def compute_similarity_and_diff(text1, text2):
    dmp = diff_match_patch()
    dmp.Diff_Timeout = 0.0
    diff = dmp.diff_main(text1, text2, False)

    # similarity
    common_text = sum([len(txt) for op, txt in diff if op == 0])
    text_length = max(len(text1), len(text2))
    sim = common_text / text_length

    return sim, diff

Another approach, that doesn't involve adding columns to the result, is to simply zero-out the day component of the date, so 2016-07-13 and 2016-07-16 would both be 2016-07-01 - thus making them equal by month.

If you have a date (not a datetime) value, then you can zero it directly:

SELECT
    DATEADD( day, 1 - DATEPART( day, [Date] ), [Date] ),
    COUNT(*)
FROM
    [Table]
GROUP BY
    DATEADD( day, 1 - DATEPART( day, [Date] ), [Date] )

If you have datetime values, you'll need to use CONVERT to remove the time-of-day portion:

SELECT
    DATEADD( day, 1 - DATEPART( day, [Date] ),  CONVERT( date, [Date] ) ),
    COUNT(*)
FROM
    [Table]
GROUP BY
    DATEADD( day, 1 - DATEPART( day, [Date] ),  CONVERT( date, [Date] ) )

In this case, your test.js will not run, because you're loading it before jQuery. put it after jQuery:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<script type="text/javascript" src="test.js"></script>

It's because of x and y offset. Try this:

-webkit-box-shadow: 0 0 10px #fff;
        box-shadow: 0 0 10px #fff;

edit (year later..): Made the answer more cross-browser, as requested in comments :)

btw: there are many css3 generator nowadays.. css3.me, css3maker, css3generator etc...

In my case the ajax call was being interfered by the data-plugin tag applied to the table. The data-plugin does background initialization and will give this error when you have it as well as yourTable.DataTable({ ... }); initialization.

From

 <table id="myTable" class="table-class" data-plugin="dataTable" data-source="data-source">

To

<table id="myTable" class="table-class" data-source="data-source">

You can get a list of column names by running:

SELECT name FROM PRAGMA_TABLE_INFO('your_table');
name      
tbl_name  
rootpage  
sql

You can check if a certain column exists by running:

SELECT 1 FROM PRAGMA_TABLE_INFO('your_table') WHERE name='sql';
1

I had a similar problem and update the input[type="number"] example on angular docs for works with decimals precision and I'm using this approach to solve it.

PS: A quick reminder is that the browsers supports the characters 'e' and 'E' in the input[type="number"], because that the keypress event is required.

angular.module('numfmt-error-module', [])
.directive('numbersOnly', function() {
  return {
    require: 'ngModel',
    scope: {
      precision: '@'
    },
    link: function(scope, element, attrs, modelCtrl) {
      var currencyDigitPrecision = scope.precision;

      var currencyDigitLengthIsInvalid = function(inputValue) {
        return countDecimalLength(inputValue) > currencyDigitPrecision;
      };

      var parseNumber = function(inputValue) {
        if (!inputValue) return null;
        inputValue.toString().match(/-?(\d+|\d+.\d+|.\d+)([eE][-+]?\d+)?/g).join('');
        var precisionNumber = Math.round(inputValue.toString() * 100) % 100;

        if (!!currencyDigitPrecision && currencyDigitLengthIsInvalid(inputValue)) {
          inputValue = inputValue.toFixed(currencyDigitPrecision);
          modelCtrl.$viewValue = inputValue;
        }
        return inputValue;
      };

      var countDecimalLength = function (number) { 
         var str = '' + number;
         var index = str.indexOf('.');
         if (index >= 0) {
           return str.length - index - 1;
         } else {
           return 0;
         }
      };

      element.on('keypress', function(evt) {
        var charCode, isACommaEventKeycode, isADotEventKeycode, isANumberEventKeycode;
        charCode = String.fromCharCode(evt.which || event.keyCode);
        isANumberEventKeycode = '0123456789'.indexOf(charCode) !== -1;
        isACommaEventKeycode = charCode === ',';
        isADotEventKeycode = charCode === '.';

        var forceRenderComponent = false;

        if (modelCtrl.$viewValue != null && !!currencyDigitPrecision) {
          forceRenderComponent = currencyDigitLengthIsInvalid(modelCtrl.$viewValue);
        }

        var isAnAcceptedCase = isANumberEventKeycode || isACommaEventKeycode || isADotEventKeycode;

        if (!isAnAcceptedCase) {
          evt.preventDefault();
        }

        if (forceRenderComponent) {
          modelCtrl.$render(modelCtrl.$viewValue);
        }

        return isAnAcceptedCase;
      });

      modelCtrl.$render = function(inputValue) {
        return element.val(parseNumber(inputValue));
      };

      modelCtrl.$parsers.push(function(inputValue) {

        if (!inputValue) {
          return inputValue;
        }

        var transformedInput;
        modelCtrl.$setValidity('number', true);
        transformedInput = parseNumber(inputValue);

        if (transformedInput !== inputValue) {

          modelCtrl.$viewValue = transformedInput;
          modelCtrl.$commitViewValue();
          modelCtrl.$render(transformedInput);
        }
        return transformedInput;
      });
    }
  };
});

And in your html you can use this approach

<input 
  type="number" 
  numbers-only 
  precision="2" 
  ng-model="model.value" 
  step="0.10" />

Here is the plunker with this snippet

In storyboard you have two choise:

1. set the control's 'enable' to false.

2. set the view's 'user interaction enable' false

The diffierence between these choise is:

the appearance of UITextfild to display in the screen.

1. First is set the control's enable. You can see the backgroud color is changed.
2. Second is set the view's 'User interaction enable'. The backgroud color is NOT changed.

Within code:

1. textfield.enable = false

2. textfield.userInteractionEnabled = NO

   Updated for Swift 3

   1. textField.isEnabled = false
   2. textfield.isUserInteractionEnabled = false

if you have the BluetoothDevice object you can create bond(pair) from api 19 onwards with bluetoothDevice.createBond() method.

Edit

for callback, if the request was accepted or denied you will have to create a BroadcastReceiver with BluetoothDevice.ACTION_BOND_STATE_CHANGED action

You could simply use Runtime.exec()

As others have said, you've probably got duplicate values in your original index. To find them do this:

df[df.index.duplicated()]

You should look at the members of the thrown exception, particularly .Message and .InnerException.

I would also see whether or not the documentation for InvokeMethod tells you whether it throws some more specialized Exception class than Exception - such as the Win32Exception suggested by @Preet. Catching and just looking at the Exception base class may not be particularly useful.

This is cross-browser and fully responsive:

<iframe

  style="
    position: fixed;
    top: 0px;
    bottom: 0px;
    right: 0px;
    width: 100%;
    border: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    z-index: 999999;
    height: 100%;
  ">
</iframe>

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

If there is a huge amount of files on a network folder using the wildcard is questionable (speed, or command line arguments overflow).

I ended up with:

if [ -n "$(find somedir/that_may_not_exist_yet -maxdepth 1 -name \*.ext -print -quit)" ] ; then
  echo Such file exists
fi

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

To convert the object to a byte array use the concept of Serialization and De-serialization.

You can employ the use of data in jQuery and catch all of the events which then tests it against it's last value (untested):

$(document).ready(function() {  
    $("#fieldId").bind("keyup keydown keypress change blur", function() {
        if ($(this).val() != jQuery.data(this, "lastvalue") {
         alert("changed");
        }
        jQuery.data(this, "lastvalue", $(this).val());
    });
});

This would work pretty good against a long list of items too. Using jQuery.data means you don't have to create a javascript variable to track the value. You could do $("#fieldId1, #fieldId2, #fieldId3, #fieldId14, etc") to track many fields.

UPDATE: Added blur to the bind list.

Try running fuser command

[root@guest2 ~]# fuser -mv /home

USER PID ACCESS COMMAND

/home: root 2919 f.... automount

[root@guest2 ~]# kill -9 2919

autofs service is known to cause this issue.

You can use command

#service autofs stop

And try again.

Needed the form elements named in the HTML as an array to be an array in the javascript object, as if the form was actually submitted.

If there is a form with multiple checkboxes such as:

<input name='breath[0]' type='checkbox' value='presence0'/>
<input name='breath[1]' type='checkbox' value='presence1'/>
<input name='breath[2]' type='checkbox' value='presence2'/>
<input name='serenity'  type='text' value='Is within the breath.'/>
...

The result is an object with:

data = {
   'breath':['presence0','presence1','presence2'],
   'serenity':'Is within the breath.'
}


var $form = $(this),
    data  = {};

$form.find("input").map(function()
{
    var $el  = $(this),
        name = $el.attr("name");

    if (/radio|checkbox/i.test($el.attr('type')) && !$el.prop('checked'))return;

    if(name.indexOf('[') > -1)
    {
        var name_ar = name.split(']').join('').split('['),
            name    = name_ar[0],
            index   = name_ar[1];

        data[name]  = data[name] || [];
        data[name][index] = $el.val();
    }
    else data[name] = $el.val();
});

And there are tons of answers here which helped improve my code, but they were either too complex or didn't do exactly want I wanted: Convert form data to JavaScript object with jQuery

Works but can be improved: only works on one-dimensional arrays and the resulting indexes may not be sequential. The length property of an array returns the next index number as the length of the array, not the actually length.

Hope this helped. Namaste!

Generic Webhook Trigger Plugin can be configured with filters to achieve this.

When configured with

• A variable named ref and expression $.ref.
• A filter with text $ref and filter expression like ^refs/heads/master$.

Then that job will trigger for every push to master. No polling.

You probably want more values from the webhook to actually perform the build. Just add more variables, with JSONPath, to pick what you need.

There are some use cases here: https://github.com/jenkinsci/generic-webhook-trigger-plugin/tree/master/src/test/resources/org/jenkinsci/plugins/gwt/bdd

One more time, building off of @RalphyZ

This one doesn't break the exposed API.

from argparse import ArgumentParser, SUPPRESS
# Disable default help
parser = ArgumentParser(add_help=False)
required = parser.add_argument_group('required arguments')
optional = parser.add_argument_group('optional arguments')

# Add back help 
optional.add_argument(
    '-h',
    '--help',
    action='help',
    default=SUPPRESS,
    help='show this help message and exit'
)
required.add_argument('--required_arg', required=True)
optional.add_argument('--optional_arg')

Which will show the same as above and should survive future versions:

usage: main.py [-h] [--required_arg REQUIRED_ARG]
           [--optional_arg OPTIONAL_ARG]

required arguments:
  --required_arg REQUIRED_ARG

optional arguments:
  -h, --help                    show this help message and exit
  --optional_arg OPTIONAL_ARG

Solution for Preact with preact-router

Works with refresh and direct access

For those discovering this via Google, here's a demo of preact-router + hash history:

const { h, Component, render } = preact; /** @jsx h */
const { Router } = preactRouter;
const { createHashHistory } = History;
const App = () => (
    <div>
        <AddressBar />

        <Router history={createHashHistory()}>
            <div path="/">
                <p>
                    all paths in preact-router are still /normal/urls.
                    using hash history rewrites them to /#/hash/urls
                </p>
                Example: <a href="/page2">page 2</a>
            </div>
            <div path="/page2">
                <p>Page Two</p>
                <a href="/">back to home</a><br/>
            </div>
        </Router>
    </div>
);

jsfiddle

To print subprocess' output line-by-line as soon as its stdout buffer is flushed in Python 3:

from subprocess import Popen, PIPE, CalledProcessError

with Popen(cmd, stdout=PIPE, bufsize=1, universal_newlines=True) as p:
    for line in p.stdout:
        print(line, end='') # process line here

if p.returncode != 0:
    raise CalledProcessError(p.returncode, p.args)

Notice: you do not need p.poll() -- the loop ends when eof is reached. And you do not need iter(p.stdout.readline, '') -- the read-ahead bug is fixed in Python 3.

See also, Python: read streaming input from subprocess.communicate().

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

For reference, it's 2018 and I'm using BS4.1

It maybe is not the best way to do it. But the only I found to get the Absolute path is to calculate how many times the syntax .. was in the string and then use the function gotoparent as many times that syntax comes in the hyperlink adress. (in my case, my field is a hyperlink address. Ps: This code requires the reference to microsoft scripting runtime

Function AbsolutePath(strRelativePath As String, strCurrentFileName As String) As String
Dim fso As Object
Dim strCurrentProjectpath As String
Dim strGoToParentFolder As String
Dim strOrigineFolder As String
Dim strPath As String
Dim lngParentFolder As Long


''Pour retrouver le répertoire parent
Set fso = CreateObject("Scripting.FileSystemObject")

'' détermine le répertire du projet actif
strCurrentProjectpath = CurrentProject.Path

'' détermine le nom du répertoire dans lequel le fichier d'origine se trouve
strOrigineFolder = Replace(Replace(Replace(strRelativePath, strCurrentFileName, ""), "..", ""), "\", "")

''Extraction du chemin relatif (ex. ..\..\..)
strGoToParentFolder = Replace(Replace(strRelativePath, strOrigineFolder, ""), strCurrentFileName, "")

''retourne le nombre de fois qu'il faut remonter au répertoire parent
lngParentsFolder = Len(Replace(strGoToParentFolder, "\", "")) / 2

''détermine la valeur d'origine du répertoire du début
strPath = strCurrentProjectpath

Vérifie s 'il faut aller au répertoire parent
If lngParentsFolder < 1 Then
    'si non, alors répertoire parent et répertoire d'origine du fichier
    strPath = strCurrentProjectpath & "\" & strOrigineFolder
Else
    ''si oui, nous faisons la boucle pour retourner au répertoire d'origine
    For i = 1 To lngParentsFolder
        strPath = fso.GetParentFolderName(strPath)
    Next i
End If

''retournons le répertoire parent du fichier et son répertoire d'origine [le OUTPUT]
AbsolutePath = strPath & strOrigineFolder & "\"

End Function

My solution doesn't require the addition of external tools or scripting languages --it's pretty much guaranteed to work on your build machine. I solve this problem in several parts. First, I have created a BUILD.BAT file that converts the Jenkins BUILD_NUMBER parameter into an environment variable. I use Jenkins's "Execute Windows batch command" function to run the build batch file by entering the following information for the Jenkins build:

     ./build.bat --build_id %BUILD_ID% -build_number %BUILD_NUMBER%

In the build environment, I have a build.bat file that starts as follows:

     rem build.bat
     set BUILD_ID=Unknown
     set BUILD_NUMBER=0
     :parse_command_line
     IF NOT "%1"=="" (
         IF "%1"=="-build_id" (
             SET BUILD_ID=%2
             SHIFT
             )
         IF "%1"=="-build_number" (
             SET BUILD_NUMBER=%2
             SHIFT
         )
         SHIFT
         GOTO :parse_command_line
     )
     REM your build continues with the environmental variables set
     MSBUILD.EXE YourProject.sln

Once I did that, I right-clicked on the project to be built in Visual Studio's Solution Explorer pane and selected Properties, select Build Events, and entered the following information as the Pre-Build Event Command Line, which automatically creates a .cs file containing build number information based on current environment variable settings:

     set VERSION_FILE=$(ProjectDir)\Properties\VersionInfo.cs
     if !%BUILD_NUMBER%==! goto no_buildnumber_set
     goto buildnumber_set
     :no_buildnumber_set
     set BUILD_NUMBER=0
     :buildnumber_set
     if not exist %VERSION_FILE% goto no_version_file
     del /q %VERSION_FILE%
     :no_version_file
     echo using System.Reflection; >> %VERSION_FILE%
     echo using System.Runtime.CompilerServices; >> %VERSION_FILE%
     echo using System.Runtime.InteropServices; >> %VERSION_FILE%
     echo [assembly: AssemblyVersion("0.0.%BUILD_NUMBER%.1")] >> %VERSION_FILE%
     echo [assembly: AssemblyFileVersion("0.0.%BUILD_NUMBER%.1")] >> %VERSION_FILE%

You may need to adjust to your build taste. I build the project manually once to generate an initial Version.cs file in the Properties directory of the main project. Lastly, I manually include the Version.cs file into the Visual Studio solution by dragging it into the Solution Explorer pane, underneath the Properties tab for that project. In future builds, Visual Studio then reads that .cs file at Jenkins build time and gets the correct build number information out of it.

I was facing same error with Django Rest Framework, It was nothing to do with UI, still was getting this error. I applied below solution, worked for me.

• Restarted Machine.
• Restarted Virtual Environment.

How about some examples to show it in action...

@Test
public void isInstanceOf() {
    Exception anEx1 = new Exception("ex");
    Exception anEx2 = new RuntimeException("ex");
    RuntimeException anEx3 = new RuntimeException("ex");

    //Base case, handles inheritance
    Assert.assertTrue(anEx1 instanceof Exception);
    Assert.assertTrue(anEx2 instanceof Exception);
    Assert.assertTrue(anEx3 instanceof Exception);

    //Other cases
    Assert.assertFalse(anEx1 instanceof RuntimeException);
    Assert.assertTrue(anEx2 instanceof RuntimeException);
    Assert.assertTrue(anEx3 instanceof RuntimeException);
}

@Test
public void isAssignableFrom() {
    Exception anEx1 = new Exception("ex");
    Exception anEx2 = new RuntimeException("ex");
    RuntimeException anEx3 = new RuntimeException("ex");

    //Correct usage = The base class goes first
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx1.getClass()));
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx2.getClass()));
    Assert.assertTrue(Exception.class.isAssignableFrom(anEx3.getClass()));

    //Incorrect usage = Method parameter is used in the wrong order
    Assert.assertTrue(anEx1.getClass().isAssignableFrom(Exception.class));
    Assert.assertFalse(anEx2.getClass().isAssignableFrom(Exception.class));
    Assert.assertFalse(anEx3.getClass().isAssignableFrom(Exception.class));
}

If you have spaces in the filename, try these:

[file](./file%20with%20spaces.md)
[file](<./file with spaces.md>)

First one seems more reliable

Yes this is possible Since the question is update, this solution can only gives you the embed url not the HLS url, check @JAL answer. with the ressource search.list and the parameters:

* part: id
* channelId: UCURGpU4lj3dat246rysrWsw
* eventType: live
* type: video

Request :

GET https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCURGpU4lj3dat246rysrWsw&eventType=live&type=video&key={YOUR_API_KEY}

Result:

 "items": [
  {
   "kind": "youtube#searchResult",
   "etag": "\"DsOZ7qVJA4mxdTxZeNzis6uE6ck/enc3-yCp8APGcoiU_KH-mSKr4Yo\"",
   "id": {
    "kind": "youtube#video",
    "videoId": "WVZpCdHq3Qg"
   }
  },

Then get the videoID value WVZpCdHq3Qg for example and add the value to this url:

https://www.youtube.com/embed/ + videoID
https://www.youtube.com/watch?v= + videoID

You can simply use Arrays.sort()

array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));

Working Example :

var array = [{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"VPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""},},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"adfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"bbfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}}];_x000D_
array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));_x000D_
 _x000D_
 console.log(array);

You could do it with the toFixed function, but it's buggy in IE. If you want a reliable solution, look at my answer here.

If you have MFA enabled on GitLab you should go to Repository Settings/Repository ->Deploy Keys and create one, then use it as login while importing repo on GitHub

The simplest approach is to use a multitouch JavaScript library like Hammer.js. Then you can write code like:

canvas
    .hammer({prevent_default: true})
    .bind('doubletap', function(e) { // And double click
        // Zoom-in
    })
    .bind('dragstart', function(e) { // And mousedown
        // Get ready to drag
    })
    .bind('drag', function(e) { // And mousemove when mousedown
        // Pan the image
    })
    .bind('dragend', function(e) { // And mouseup
        // Finish the drag
    });

And you can keep going. It supports tap, double tap, swipe, hold, transform (i.e., pinch) and drag. The touch events also fire when equivalent mouse actions happen, so you don't need to write two sets of event handlers. Oh, and you need the jQuery plugin if you want to be able to write in the jQueryish way as I did.

I find answer. Thanks all but right answer next:

$("#myModal").on("hidden", function () {
  $('#result').html('yes,result');
});

Events here http://bootstrap-ru.com/javascript.php#modals

UPD

For Bootstrap 3.x need use hidden.bs.modal:

$("#myModal").on("hidden.bs.modal", function () {
  $('#result').html('yes,result');
});

select convert(varchar(10), cast(fmdate as date), 101) from sery

Without cast I was not getting fmdate converted, so fmdate was a string.

for some iPhone you have to put your viewport like this

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, shrink-to-fit=no, user-scalable=0" />

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:

HOME=c

An environment variable is a regular variable that has been marked for export to the environment.

export HOME
HOME=c

You can combine the assignment with the export statement.

export HOME=c

You can check for IsNull condition.

If IsNull({TABLE.FIELD}) or {TABLE.FIELD} = "" then
  // do something

Use a dictionary!!

You can also use dictionaries that allows you to have more control over the plots:

import matplotlib.pyplot as plt
#   plot 0     plot 1    plot 2   plot 3
x=[[1,2,3,4],[1,4,3,4],[1,2,3,4],[9,8,7,4]]
y=[[3,2,3,4],[3,6,3,4],[6,7,8,9],[3,2,2,4]]

plots = zip(x,y)
def loop_plot(plots):
    figs={}
    axs={}
    for idx,plot in enumerate(plots):
        figs[idx]=plt.figure()
        axs[idx]=figs[idx].add_subplot(111)
        axs[idx].plot(plot[0],plot[1])
return figs, axs

figs, axs = loop_plot(plots)

Now you can select the plot that you want to modify easily:

axs[0].set_title("Now I can control it!")

Of course, is up to you to decide what to do with the plots. You can either save them to disk figs[idx].savefig("plot_%s.png" %idx) or show them plt.show(). Use the argument block=False only if you want to pop up all the plots together (this could be quite messy if you have a lot of plots). You can do this inside the loop_plot function or in a separate loop using the dictionaries that the function provided.

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

SUM is an aggregate function. It will calculate the total for each group. + is used for calculating two or more columns in a row.

Consider this example,

ID  VALUE1  VALUE2
===================
1   1       2
1   2       2
2   3       4
2   4       5

SELECT  ID, SUM(VALUE1), SUM(VALUE2)
FROM    tableName
GROUP   BY ID

will result

ID, SUM(VALUE1), SUM(VALUE2)
1   3           4
2   7           9

SELECT  ID, VALUE1 + VALUE2
FROM    TableName

will result

ID, VALUE1 + VALUE2
1   3
1   4
2   7
2   9

SELECT  ID, SUM(VALUE1 + VALUE2)
FROM    tableName
GROUP   BY ID

will result

ID, SUM(VALUE1 + VALUE2)
1   7
2   16

This might be a bit faster:

dir /A:-D /B *.* 2>nul | find /c /v ""

`/A:-D` - filters out only non directory items (files)
`/B`    - prints only file names (no need a full path request)
`*.*`   - can filters out specific file names (currently - all)
`2>nul` - suppresses all error lines output to does not count them

Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT

Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.

As you've discovered above, you can use a combination of window.onbeforeunload and $locationChangeStart to message the user. In addition, you can utilize ngForm.$dirty to only message the user when they have made changes.

I've written an angularjs directive that you can apply to any form that will automatically watch for changes and message the user if they reload the page or navigate away. @see https://github.com/facultymatt/angular-unsavedChanges

Hopefully you find this directive useful!

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

select (floor(((DATE2-DATE1)*24*60*60)/3600)|| ' : ' ||floor((((DATE2-DATE1)*24*60*60) -floor(((DATE2-DATE1)*24*60*60)/3600)*3600)/60)|| '  ' ) as time_difference from TABLE1 

This may be a common problem for new users of Matplotlib to draw vertical and horizontal lines. In order to understand this problem, you should be aware that different coordinate systems exist in Matplotlib.

The method axhline and axvline are used to draw lines at the axes coordinate. In this coordinate system, coordinate for the bottom left point is (0,0), while the coordinate for the top right point is (1,1), regardless of the data range of your plot. Both the parameter xmin and xmax are in the range [0,1].

On the other hand, method hlines and vlines are used to draw lines at the data coordinate. The range for xmin and xmax are the in the range of data limit of x axis.

Let's take a concrete example,

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 5, 100)
y = np.sin(x)

fig, ax = plt.subplots()

ax.plot(x, y)
ax.axhline(y=0.5, xmin=0.0, xmax=1.0, color='r')
ax.hlines(y=0.6, xmin=0.0, xmax=1.0, color='b')

plt.show()

It will produce the following plot:

The value for xmin and xmax are the same for the axhline and hlines method. But the length of produced line is different.

The library io-extras may be useful. For example if you want to gzip an InputStream using GZIPOutputStream and you want it to happen synchronously (using the default buffer size of 8192):

InputStream is = ...
InputStream gz = IOUtil.pipe(is, o -> new GZIPOutputStream(o));

Note that the library has 100% unit test coverage (for what that's worth of course!) and is on Maven Central. The Maven dependency is:

<dependency>
  <groupId>com.github.davidmoten</groupId>
  <artifactId>io-extras</artifactId>
  <version>0.1</version>
</dependency>

Be sure to check for a later version.

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

You may change the pg_hba.conf and then reload the postgresql. something in the pg_hba.conf may be like below:

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

then you change your user to postgresql, you may login successfully.

su postgresql

Surround that select with parentheses.

SET @v1 := (SELECT COUNT(*) FROM user_rating);
SELECT @v1;

There are my config to support L and old versions of android:

apply plugin: 'com.android.application'

android {
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.uladzimir_klyshevich.myapplication"
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    productFlavors {
        l {
            minSdkVersion 'android-L'
            targetSdkVersion 'android-L'
            compileSdkVersion 'android-L'
        }
        old {
            minSdkVersion 10
            targetSdkVersion 20
            //TODO comment second line if build is not compiles for "L"
            compileSdkVersion 20
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    lCompile 'com.android.support:appcompat-v7:21.+'
    oldCompile 'com.android.support:appcompat-v7:19.1.0'
}

As result you will have flavors:

oldDebug
oldRelease
lDebug
lRelease

And can install your application on old versions of android.

Here's an implementation using node-http-proxy from nodejitsu.

var http = require('http');
var httpProxy = require('http-proxy');
var proxy = httpProxy.createProxyServer({});

http.createServer(function(req, res) {
    proxy.web(req, res, { target: 'http://www.google.com' });
}).listen(3000);

In my case, changing the order of Maven Dependencies from Build Path configuration did not work for me. I changed its order from Run configuration.
Follow these steps:
• Go to Run -> Run Configurations...
• Click on the unit test's run configuration and click on the Classpath tab.
• check Use temporary JAR to specify classpath (to avoid classpath length limitations).
May be it is enough and your test works. You should try, so press Run button. If it did not work. Follow all previous steps again and without pressing Run button, go to the next step.
• In sub branches of User Entries move Maven Dependencies above your project or test class.
• Click Run button.

Yes. Look at http://jerrywickey.com/test/testJerrysLibrary.php

It gives sample code examples for RSA encryption and decryption in PHP as well as RSA encryption in javascript.

If you want to encrypt text instead of just base 10 numbers, you'll also need a base to base conversion. That is convert text to a very large number. Text is really just writing in base 63. 26 lowercase letters plus 26 uppercase + 10 numerals + space character. The code for that is below also.

The $GETn parameter is a file name that holds keys for the cryption functions. If you don't figure it out, ask. I'll help.

I actually posted this whole encryption library yesterday, but Brad Larson a mod, killed it and said this kind of stuff isn't really what Stack Overflow is about. But you can still find all the code examples and the whole function library to carry out client/server encryption decryption for AJAX at the link above.

Theres two properties on the model you need to set. The first $primaryKey to tell the model what column to expect the primary key on. The second $incrementing so it knows the primary key isn't a linear auto incrementing value.

class MyModel extends Model
{
    protected $primaryKey = 'my_column';

    public $incrementing = false;
}

For more info see the Primary Keys section in the documentation on Eloquent.

Your HttpServletRequest object has a getParameter(String paramName) method that can be used to get parameter values. http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.html#getParameter(java.lang.String)

I would suggest that you just write the case statement yourself using datename():

select (case datename(dw, aws.date)
             when 'Monday' then 1
             when 'Tuesday' then 2
             when 'Wednesday' then 3
             when 'Thursday' then 4
             when 'Friday' then 5
             when 'Saturday' then 6
             when 'Sunday' then 7
        end)

At least, this won't change if someone changes the parameter on the day of the week when weeks begin. On the other hand, it is susceptible to the language chosen for SQL Server.

I just accomplished the opposite of this using :after and ::after because I needed to make my bottom border exactly 1.3rem wider:

My element got super deformed when I used :before and :after at the same time because the elements are horizontally aligned with display: flex, flex-direction: row and align-items: center.

You could use this for making something wider or narrower, or probably any mathematical dimension mods:

a.nav_link-active {
  color: $e1-red;
  margin-top: 3.7rem;
}
a.nav_link-active:visited {
  color: $e1-red;
}
a.nav_link-active:after {
  content: '';
  margin-top: 3.3rem;      // margin and height should
  height: 0.4rem;          // add up to active link margin
  background: $e1-red;
  margin-left: -$nav-spacer-margin;
  display: block;
}
a.nav_link-active::after {
  content: '';
  margin-top: 3.3rem;      // margin and height should
  height: 0.4rem;          // add up to active link margin
  background: $e1-red;
  margin-right: -$nav-spacer-margin;
  display: block;
}

Sorry, this is SCSS, just multiply the numbers by 10 and change the variables with some normal values.

It is possible but not the way you have it.

You have to add a no-args constructor to the base class and that's it!

public abstract class A {
    private String name;
    public A(){
        this.name = getName();
    }
    public abstract String getName();


    public String toString(){
        return "simple class name: " + this.getClass().getSimpleName() + " name:\"" + this.name + "\"";
    }
}
class B extends A {
    public String getName(){
        return "my name is B";
    }
    public static void main( String [] args ) {
        System.out.println( new C() );
    }
}
class C extends A {
    public String getName() {
        return "Zee";
    }
}

When you don't add a constructor ( any ) to a class the compiler add the default no arg contructor for you.

When the defualt no arg calls to super(); and since you don't have it in the super class you get that error message.

That's about the question it self.

Now, expanding the answer:

Are you aware that creating a subclass ( behavior ) to specify different a different value ( data ) makes no sense??!!! I hope you do.

If the only thing that is changes is the "name" then a single class parametrized is enough!

So you don't need this:

MyClass a = new A("A");
MyClass b = new B("B");
MyClass c = new C("C");
MyClass d = new D("D");

or

MyClass a = new A(); // internally setting "A" "B", "C" etc.
MyClass b = new B();
MyClass c = new C();
MyClass d = new D();

When you can write this:

MyClass a = new MyClass("A");
MyClass b = new MyClass("B");
MyClass c = new MyClass("C");
MyClass d = new MyClass("D");

If I were to change the method signature of the BaseClass constructor, I would have to change all the subclasses.

Well that's why inheritance is the artifact that creates HIGH coupling, which is undesirable in OO systems. It should be avoided and perhaps replaced with composition.

Think if you really really need them as subclass. That's why you see very often interfaces used insted:

 public interface NameAware {
     public String getName();
 }



 class A implements NameAware ...
 class B implements NameAware ...
 class C ... etc. 

Here B and C could have inherited from A which would have created a very HIGH coupling among them, by using interfaces the coupling is reduced, if A decides it will no longer be "NameAware" the other classes won't broke.

Of course, if you want to reuse behavior this won't work.

what this means ? is there any problem in my code

It means that you are accessing a location or index which is not present in collection.

To find this, Make sure your Gridview has 5 columns as you are using it's 5th column by this line

dataGridView1.Columns[4].Name = "Amount";

Here is the image which shows the elements of an array. So if your gridview has less column then the (index + 1) by which you are accessing it, then this exception arises.

You can display the ActiveRecord generated SQL:

Before the query runs:

$this->db->_compile_select(); 

And after it has run:

$this->db->last_query(); 

Now there are so many ways to apply font one of easiest way is like this, 1) Right-click the res folder go to New > Android resource directory.

2) From Resource type list, select font, and then click OK.

3) Put your font files in the font folder.

If it's not working from web.config, you need to set it from IIS.

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

// date format, it will be like "2015-01-01"
private static final String DATE_FORMAT = "yyyy-MM-dd";

// convert a string to java.util.Date
public static Date convertStringToJavaDate(String date)
        throws ParseException {
    DateFormat dataFormat = new SimpleDateFormat(DATE_FORMAT);
    return dataFormat.parse(date);
}

// plus days to a date
public static Date plusJavaDays(Date date, int days) {
    // convert to jata-time
    DateTime fromDate = new DateTime(date);
    DateTime toDate = fromDate.plusDays(days);
    // convert back to java.util.Date
    return toDate.toDate();
}

// return a list of dates between the fromDate and toDate
public static List<Date> getDatesBetween(Date fromDate, Date toDate) {
    List<Date> dates = new ArrayList<Date>(0);
    Date date = fromDate;
    while (date.before(toDate) || date.equals(toDate)) {
        dates.add(date);
        date = plusJavaDays(date, 1);
    }
    return dates;
}

You are calling a non-static method :

public function foobarfunc() {
    return $this->foo();
}

Using a static-call :

foobar::foobarfunc();

When using a static-call, the function will be called (even if not declared as static), but, as there is no instance of an object, there is no $this.

So :

• You should not use static calls for non-static methods
• Your static methods (or statically-called methods) can't use $this, which normally points to the current instance of the class, as there is no class instance when you're using static-calls.

Here, the methods of your class are using the current instance of the class, as they need to access the $foo property of the class.

This means your methods need an instance of the class -- which means they cannot be static.

This means you shouldn't use static calls : you should instanciate the class, and use the object to call the methods, like you did in your last portion of code :

$foobar = new foobar();
$foobar->foobarfunc();

For more informations, don't hesitate to read, in the PHP manual :

• The Classes and Objects section
• And the Static Keyword page.

Also note that you probably don't need this line in your __construct method :

global $foo;

Using the global keyword will make the $foo variable, declared outside of all functions and classes, visibile from inside that method... And you probably don't have such a $foo variable.

To access the $foo class-property, you only need to use $this->foo, like you did.

dat <- dat[-1, ] worked but it killed my dataframe, changing it into another type. Had to instead use dat <- data.frame(dat[-1, ]) but this is possibly a special case as this dataframe initially had only one column.

Probably you just needed this CSS rule:

table {
   border-spacing: 0px;
}

This expands on @Reigel's answer. It will return an answer for horizontal or vertical scrollbars.

(function($) {
    $.fn.hasScrollBar = function() {
        var e = this.get(0);
        return {
            vertical: e.scrollHeight > e.clientHeight,
            horizontal: e.scrollWidth > e.clientWidth
        };
    }
})(jQuery);

Example:

element.hasScrollBar()             // Returns { vertical: true/false, horizontal: true/false }
element.hasScrollBar().vertical    // Returns true/false
element.hasScrollBar().horizontal  // Returns true/false

<input type="text" (keypress)="keyPress($event)">


  keyPress(event: any) {
    const pattern = /[0-9\+\-\ ]/;

    let inputChar = String.fromCharCode(event.charCode);
    if (event.keyCode != 8 && !pattern.test(inputChar)) {
      event.preventDefault();
    }
  }

You can add it in the options of your form class:

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\MyEntity',
        'attr' => array(
            'class' => 'form-horizontal'
        )
    ));
}

I found the next command

mvn dependency:copy-dependencies -Dclassifier=sources

here maven.apache.org

That would do the trick in a Mac :

ping $(ifconfig en0 | awk '$1 == "inet" {print $2}')

That resolved to ping 192.168.1.2 in my machine.

Pro tip: $(...) means run whatever is inside the parentheses in a subshell and return that as the value.

For compiling the java file having dependency on a jar

javac -cp path_of_the_jar/jarName.jar className.java

For executing the class file

java -cp .;path_of_the_jar/jarName.jar className

var targetNode = document.getElementById('elementId');
var observer = new MutationObserver(function(){
    if(targetNode.style.display != 'none'){
        // doSomething
    }
});
observer.observe(targetNode, { attributes: true, childList: true });

I might be a little late, but you could just use the MutationObserver to observe any changes on the desired element. If any change occurs, you'll just have to check if the element is displayed.

Add a custom attribute to <input type="file" file-accept="jpg gif jpeg png bmp"> and read the filenames within javascript that matches the extension provided by the attribute file-accept. This will be kind of bogus, as a text file with any of the above extension will erroneously deteted as image.

I agree with pez and some here.

It seems obvious to me that "new" is self descriptive object creation, where the YUI pattern Greg Dean describes is completely obscured.

The possibility someone could write var bar = foo; or var bar = baz(); where baz isn't an object creating method seems far more dangerous.

You'll have to set it to zero. Zero means the script can run forever. Add the following at the start of your script:

ini_set('max_execution_time', 0);

Refer to the PHP documentation of max_execution_time

Note that:

set_time_limit(0);

will have the same effect.

Code for finding Length of int and decimal number:

    {
        int len,num;
        cin >> num;
        len = log10(num) + 1;
        cout << len << endl;
        return 0;
    }
    //sample input output

Upload the image on your server or in images hosting site where you get image link and then add the line on your website page where you get that image the line is

<img src="paste here your image full path"/>

Note: Calling a lifecycle method from another one is not a good practice. In below example I tried to achieve that your onNewIntent will be always called irrespective of your Activity type.

OnNewIntent() always get called for singleTop/Task activities except for the first time when activity is created. At that time onCreate is called providing to solution for few queries asked on this thread.

You can invoke onNewIntent always by putting it into onCreate method like

@Override
public void onCreate(Bundle savedState){
    super.onCreate(savedState);
    onNewIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
  super.onNewIntent(intent);
  //code
}

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

This worked for me:

export _JAVA_OPTIONS="-Xmx1g"

It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:

java -XshowSettings:vm 

and it will tell you:

Picked up _JAVA_OPTIONS: -Xmx1g

I would suggest to use django-model-utils instead of Django built-in solution. The main advantage of this solution is the lack of string declaration duplication. All choice items are declared exactly once. Also this is the easiest way for declaring choices using 3 values and storing database value different than usage in source code.

from django.utils.translation import ugettext_lazy as _
from model_utils import Choices

class MyModel(models.Model):
   MONTH = Choices(
       ('JAN', _('January')),
       ('FEB', _('February')),
       ('MAR', _('March')),
   )
   # [..]
   month = models.CharField(
       max_length=3,
       choices=MONTH,
       default=MONTH.JAN,
   )

And with usage IntegerField instead:

from django.utils.translation import ugettext_lazy as _
from model_utils import Choices

class MyModel(models.Model):
   MONTH = Choices(
       (1, 'JAN', _('January')),
       (2, 'FEB', _('February')),
       (3, 'MAR', _('March')),
   )
   # [..]
   month = models.PositiveSmallIntegerField(
       choices=MONTH,
       default=MONTH.JAN,
   )

• This method has one small disadvantage: in any IDE (eg. PyCharm) there will be no code completion for available choices (it’s because those values aren’t standard members of Choices class).

I love extension methods and this is the one I use...

static class StringHelpers
{
    public static bool ToBoolean(this String input, out bool output)
    {
        //Set the default return value
        output = false;

        //Account for a string that does not need to be processed
        if (input == null || input.Length < 1)
            return false;

        if ((input.Trim().ToLower() == "true") || (input.Trim() == "1"))
            output = true;
        else if ((input.Trim().ToLower() == "false") || (input.Trim() == "0"))
            output = false;
        else
            return false;

        //Return success
        return true;
    }
}

Then to use it just do something like...

bool b;
bool myValue;
data = "1";
if (!data.ToBoolean(out b))
  throw new InvalidCastException("Could not cast to bool value from data '" + data + "'.");
else
  myValue = b;  //myValue is True

From the accepted answer, it looks like your desired behaviour is to turn

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

You'd have to check each value against in_array:

$a=array();
// organize the array by cusip
foreach($array as $k=>$v){
    foreach($v as $key=>$value){
        if(!in_array($value, $a)){
        $a[]=$value;
        }
    }
}

Since the question on how to set fields mandatory pops up under each post, I wrote a small example on how to set fields as required:

public class ExampleDTO {
    @NotNull
    private String mandatoryParam;

    private String optionalParam;
    
    @DateTimeFormat(iso = ISO.DATE) //accept Dates only in YYYY-MM-DD
    @NotNull
    private LocalDate testDate;

    public String getMandatoryParam() {
        return mandatoryParam;
    }
    public void setMandatoryParam(String mandatoryParam) {
        this.mandatoryParam = mandatoryParam;
    }
    public String getOptionalParam() {
        return optionalParam;
    }
    public void setOptionalParam(String optionalParam) {
        this.optionalParam = optionalParam;
    }
    public LocalDate getTestDate() {
        return testDate;
    }
    public void setTestDate(LocalDate testDate) {
        this.testDate = testDate;
    }
}

//Add this to your rest controller class
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String testComplexObject (@Valid ExampleDTO e){
    System.out.println(e.getMandatoryParam() + " " + e.getTestDate());
    return "Does this work?";
}

Sub DeleteEmptyRows()  

    Worksheets("YourSheetName").Activate
    On Error Resume Next
    Columns("A").SpecialCells(xlCellTypeBlanks).EntireRow.Delete

End Sub

The following code will delete all rows on a sheet(YourSheetName) where the content of Column A is blank.

EDIT: User Defined Type Not Defined is caused by "oTable As Table" and "oRow As Row". Replace Table and Row with Object to resolve the error and make it compile.

Did you try to give the layout_width and layout_height like the following? Since you are setting with wrap_content, the image button expands to the size of source image's height and width.

<blink>    
  <ImageButton>
    android:id="@+id/Button01"
    android:scaleType="fitXY" 
    android:layout_width="80dip"
    android:layout_height="80dip"
    android:cropToPadding="false"
    android:paddingLeft="10dp"
    android:src="@drawable/eye"> 
  </ImageButton>
</blink>

If you look at the documentation you can take just the properties you're interested in from the window object i.e.

protocol + '//' + hostname + pathname

Interestingly no one answers the question, OP isn't using a strongly typed int[] but an Array.

You have to cast the Array to what it actually is, an int[], then you can use ToList:

List<int> intList = ((int[])ints).ToList();

Note that Enumerable.ToList calls the list constructor that first checks if the argument can be casted to ICollection<T>(which an array implements), then it will use the more efficient ICollection<T>.CopyTo method instead of enumerating the sequence.

The cvWaitKey simply provides something of a delay. For example:

char c = cvWaitKey(33);
if( c == 27 ) break;

Tis was apart of my code in which a video was loaded into openCV and the frames outputted. The 33 number in the code means that after 33ms, a new frame would be shown. Hence, the was a dely or time interval of 33ms between each frame being shown on the screen. Hope this helps.

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Live demo

In my case it was renaming a file to an existing file in other folder(Group) by mistake, just rename it to what it was then the error disappeared

This could be solved without VBA by the following technique.

In this example I am counting all the threes (3) in the range A:A of the sheets Page M904, Page M905 and Page M906.

List all the sheet names in a single continuous range like in the following example. Here listed in the range D3:D5.

Then by having the lookup value in cell B2, the result can be found in cell B4 by using the following formula:

=SUMPRODUCT(COUNTIF(INDIRECT("'"&D3:D5&"'!A:A"), B2))

Expanding on Xin's answer and assuming the comparison value type is INT, this approach works too:

SELECT IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)

This is a full test with example values:

DECLARE @A AS INT
DECLARE @B AS INT

SELECT  @A = 2, @B = 1
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 2

SELECT  @A = 2, @B = 3
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 3

SELECT  @A = 2, @B = NULL
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 2    

SELECT  @A = NULL, @B = 1
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 1

Go through C:\apache-tomcat-7.0.47\lib path (this path may be differ based on where you installed the Tomcat server) then past ojdbc14.jar if its not contain.

Then restart the server in eclipse then run your app on server

Another way of doing this:

Dim strings() As String = {}

Testing that it is an empty string array:

MessageBox.Show("count: " + strings.Count.ToString)

Will show a message box saying "count: 0".

I have a really stupid use case for why I got this error. Originally I was printing my data > file.txt

Then I changed my mind, and decided to use open("file.txt", "w") instead. But when I called python, I left > file.txt .....

I'd like to report a bug regarding the section Source of data to search in the first answer when using en dash (–) or em dash (—) within the filename.

More specifically, if you are about to use the first option - filenames specified as arguments, the file won't be found. As soon as you use either option 2 - stdin via redirection or 3 - data stream from a pipe, findstr will find the file.

For example, this simple batch script:

echo off
chcp 1250 > nul
set INTEXTFILE1=filename with – dash.txt
set INTEXTFILE2=filename with — dash.txt

rem 3 way of findstr use with en dashed filename
echo.
echo Filename with en dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE1%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE1%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE1%" | findstr .
echo.
echo.
rem The same set of operations with em dashed filename
echo Filename with em dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE2%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE2%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE2%" | findstr .
echo.

pause

will print:

Filename with en dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an en dash.

3. As datastream from a pipe
   I am the file with an en dash.

Filename with em dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an em dash.

3. As datastream from a pipe
   I am the file with an em dash.

Hope it helps.

Use IFNULL or COALESCE:

SELECT IFNULL(SUM(Column1), 0) AS total FROM...

SELECT COALESCE(SUM(Column1), 0) AS total FROM...

The difference between them is that IFNULL is a MySQL extension that takes two arguments, and COALESCE is a standard SQL function that can take one or more arguments. When you only have two arguments using IFNULL is slightly faster, though here the difference is insignificant since it is only called once.

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

^[a-zA-Z0-9][a-zA-Z0-9-]{1,61}[a-zA-Z0-9]\.[a-zA-Z]+(\.[a-zA-Z]+)$

This worked for me.

Object.keys(myMap).map( key => {
    console.log("key: " + key);
    console.log("value: " + myMap[key]);
});

I am using Linux and have nvm and working with more than 7 version of node As of my experience I experienced the same situation with my latest project (actually not hours but minutes as I can't wait hours because of hourly project :))

Disclaimer: don't try below option until you know how cache clean works

npm cache clean --force

and then all working fine for me so it's looks like sometimes npm's cache gets confused with different versions of Node.

I got this problem and the solution was a bit silly.

I am using Cloudflare which acts as a proxy to my website. In order to be able to login via SSH, I added an entry to my /etc/hosts file so I didn't need to remember my server's IP address.

So in my browser when I went to https://www.example.com, I was using the Cloudflare proxy, and when I went to to https://example.com I was going directly to the server. Because the Cloudflare setup doesn't require you to add the intermediate certificates, I was seeing this security exception in my browser when I went to https://example.com, but https://www.example.com was working.

The solution: remove the entry from my laptop's /etc/hosts file.

If this isn't your problem, I recommend using one of the many online SSL checker tools to try diagnose your problem.

I also recommend using ping to check the IP address being reported and check it against the IP address expected.

ping https://www.example.com/

Another very helpful SSL resource is the Mozilla SSL Configuration Generator. It can generate SSL configuration for you.

a = ('A','B','C') # see it as the string "ABC" b = ('A','B','D')

A is converted to its corresponding ASCII ord('A') #65 same for other elements

So, >> a>b # True you can think of it as comparing between string (It is exactly, actually)

the same thing goes for integers too.

x = (1,2,2) # see it the string "123" y = (1,2,3) x > y # False

because (1 is not greater than 1, move to the next, 2 is not greater than 2, move to the next 2 is less than three -lexicographically -)

The key point is mentioned in the answer above

think of it as an element is before another alphabetically not element is greater than an element and in this case consider all the tuple elements as one string.

You don't need a CTE for this

UPDATE PEDI_InvoiceDetail
SET
    DocTotal = v.DocTotal
FROM
     PEDI_InvoiceDetail
inner join 
(
   SELECT InvoiceNumber, SUM(Sale + VAT) AS DocTotal
   FROM PEDI_InvoiceDetail
   GROUP BY InvoiceNumber
) v
   ON PEDI_InvoiceDetail.InvoiceNumber = v.InvoiceNumber

This should do the trick:

TextView.setText("test");

This may help you as well. This is a conditional statement that will fill the cell with a default date if it is empty but will subtract one hour if it is a valid date/time and put it into the cell.

=IF((Sheet1!C4)="",DATE(1999,1,1),Sheet1!C4-TIME(1,0,0))

You can also substitute TIME with DATE to add or subtract a date or time.

SELECT
    t.A,
    t.B,
    t.C,
    ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS number
FROM tableZ AS t

See working example at SQLFiddle

Of course, you may want to define the row-numbering order – if so, just swap OVER (ORDER BY (SELECT 1)) for, e.g., OVER (ORDER BY t.C), like in a normal ORDER BY clause.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

your approach is pretty good...

I had this problem working with a FedEx shipment request. I perform the request with AJAX. The response includes tracking #, cost, as well as pdf string containing the shipping label.

Here's what I did:

Add a form:

<form id='getlabel' name='getlabel' action='getlabel.php' method='post' target='_blank'>
<input type='hidden' id='pdf' name='pdf'>
</form>

Use javascript to populate the hidden field's value with the pdf string and post the form.

Where getlabel.php:

<?
header('Content-Type: application/pdf');
header('Content-Length: '.strlen($_POST["pdf"]));
header('Content-Disposition: inline;');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
print $_POST["pdf"];
?>

After installing python3 with brew install python3 I was getting the error:

Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
Permission denied @ dir_s_mkdir - /usr/local/Frameworks
Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

After typing brew link python3 the error was:

Linking /usr/local/Cellar/python/3.6.4_3... Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

To solve the problem:

sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/*
brew link python3

After this, I could open python3 by typing python3

You try to set the height property of an inline element, which is not possible. You can try to make it a block element, or perhaps you meant to alter the line-height property?

is you want fix XSS on input element? you can encode string before output to input field

PHP:

$str = htmlentities($str);

C#:

str = WebUtility.HtmlEncode(str);

after that output value direct to input field:

<input type="text" value="<?php echo $str" />

For CentOS here is the working command :

There a 3 ways to implement validation:

1. Validation Rule
2. Implementation of INotifyDataErrorInfo
3. Implementation of IDataErrorInfo

Validation rule example:

public class NumericValidationRule : ValidationRule
{
    public Type ValidationType { get; set; }
    public override ValidationResult Validate(object value, CultureInfo cultureInfo)
    {
        string strValue = Convert.ToString(value);

        if (string.IsNullOrEmpty(strValue))
            return new ValidationResult(false, $"Value cannot be coverted to string.");
        bool canConvert = false;
        switch (ValidationType.Name)
        {

            case "Boolean":
                bool boolVal = false;
                canConvert = bool.TryParse(strValue, out boolVal);
                return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of boolean");
            case "Int32":
                int intVal = 0;
                canConvert = int.TryParse(strValue, out intVal);
                return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Int32");
            case "Double":
                double doubleVal = 0;
                canConvert = double.TryParse(strValue, out doubleVal);
                return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Double");
            case "Int64":
                long longVal = 0;
                canConvert = long.TryParse(strValue, out longVal);
                return canConvert ? new ValidationResult(true, null) : new ValidationResult(false, $"Input should be type of Int64");
            default:
                throw new InvalidCastException($"{ValidationType.Name} is not supported");
        }
    }
}

XAML:

Very important: don't forget to set ValidatesOnTargetUpdated="True" it won't work without this definition.

    <TextBox.Text>
        <Binding Path="Name"

            </Binding.ValidationRules>

I ran into the same problem. From my solution i came into this. So here is your code:

- root_directory
    - sub_directory_a
        - _common.scss
        - template.scss
    - sub_directory_b
        - more_styles.scss

As far i know if you want to import one scss to another its has to be a partial. When you are importing from different directory name your more_styles.scss to _more_styles.scss. Then import it into your template.scss like this @import ../sub_directory_b/_more_styles.scss. It worked for me. But as you mentioned ../sub_directory_a/_common.scss not working. That's the same directory of the template.scss. That is why it wont work.

not(:first-child) does not seem to work anymore. At least with the more recent versions of Chrome and Firefox.

Instead, try this:

ul:not(:first-of-type) {}

What you can do is use a pixmap as an icon and then put this icon onto the button.

To make sure the size of the button will be correct, you have to reisze the icon according to the pixmap size.

Something like this should work :

QPixmap pixmap("image_path");
QIcon ButtonIcon(pixmap);
button->setIcon(ButtonIcon);
button->setIconSize(pixmap.rect().size());

I wasn't satisfied with these answers since I wanted to ensure the exported values had the same ordering even when using different dicts.

Here you specify the key order upfront, the returned values will always have the same order even if the dict changes, or you use a different dict.

keys = dict1.keys()
ordered_keys1 = [dict1[cur_key] for cur_key in keys]
ordered_keys2 = [dict2[cur_key] for cur_key in keys]

Power of extension

extension Double {
    var asNumber:String {
        if self >= 0 {
            var formatter = NSNumberFormatter()
            formatter.numberStyle = .NoStyle
            formatter.percentSymbol = ""
            formatter.maximumFractionDigits = 1
            return "\(formatter.stringFromNumber(self)!)"
        }
        return ""
    }
}

let velocity:Float = 12.32982342034

println("The velocity is \(velocity.toNumber)")

Output: The velocity is 12.3

Generally speaking:

F5 may give you the same page even if the content is changed, because it may load the page from cache. But Ctrl-F5 forces a cache refresh, and will guarantee that if the content is changed, you will get the new content.

In general, I always put my enums in a struct. I have seen several guidelines including "prefixing".

enum Color
{
  Clr_Red,
  Clr_Yellow,
  Clr_Blue,
};

Always thought this looked more like C guidelines than C++ ones (for one because of the abbreviation and also because of the namespaces in C++).

So to limit the scope we now have two alternatives:

• namespaces
• structs/classes

I personally tend to use a struct because it can be used as parameters for template programming while a namespace cannot be manipulated.

Examples of manipulation include:

template <class T>
size_t number() { /**/ }

which returns the number of elements of enum inside the struct T :)

Why not use a PdfPTable object for this? Create a fixed width table and use a float array to set the widths of the columns

PdfPTable table = new PdfPTable(10);
table.HorizontalAlignment = 0;
table.TotalWidth = 500f;
table.LockedWidth = true;
float[] widths = new float[] { 20f, 60f, 60f, 30f, 50f, 80f, 50f, 50f, 50f, 50f };
table.SetWidths(widths);

addCell(table, "SER.\nNO.", 2);

addCell(table, "TYPE OF SHIPPING", 1);
addCell(table, "ORDER NO.", 1);
addCell(table, "QTY.", 1);
addCell(table, "DISCHARGE PPORT", 1);

addCell(table, "DESCRIPTION OF GOODS", 2);

addCell(table, "LINE DOC. RECL DATE", 1);

addCell(table, "CLEARANCE DATE", 2);
addCell(table, "CUSTOM PERMIT NO.", 2);
addCell(table, "DISPATCH DATE", 2);

addCell(table, "AWB/BL NO.", 1);
addCell(table, "COMPLEX NAME", 1);
addCell(table, "G. W. Kgs.", 1);
addCell(table, "DESTINATION", 1);
addCell(table, "OWNER DOC. RECL DATE", 1);

....

private static void addCell(PdfPTable table, string text, int rowspan)
{
    BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
    iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

    PdfPCell cell = new PdfPCell(new Phrase(text, times));
    cell.Rowspan = rowspan;
    cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
    cell.VerticalAlignment = PdfPCell.ALIGN_MIDDLE;
    table.AddCell(cell);
}

have a look at this tutorial too...

Add to your panel's style code something like this:

<asp:Panel ID="myPanel" runat="Server" CssClass="myPanelCSS" style="overflow-y:auto; overflow-x:hidden"></asp:Panel>

Here is a function that takes as its arguments a DataFrame and a list of columns and coerces all data in the columns to numbers.

# df is the DataFrame, and column_list is a list of columns as strings (e.g ["col1","col2","col3"])
# dependencies: pandas

def coerce_df_columns_to_numeric(df, column_list):
    df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')

So, for your example:

import pandas as pd

def coerce_df_columns_to_numeric(df, column_list):
    df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')

a = [['a', '1.2', '4.2'], ['b', '70', '0.03'], ['x', '5', '0']]
df = pd.DataFrame(a, columns=['col1','col2','col3'])

coerce_df_columns_to_numeric(df, ['col2','col3'])

If I'm starting a long-running process like a copy or hash and I want to know later how long it took, I just do this:

$ date; sha1sum reallybigfile.txt; date

Which will result in the following output:

Tue Jun  2 21:16:03 PDT 2015
5089a8e475cc41b2672982f690e5221469390bc0  reallybigfile.txt
Tue Jun  2 21:33:54 PDT 2015

Granted, as implemented here it isn't very precise and doesn't calculate the elapsed time. But it's dirt simple and sometimes all you need.

I would suspect that there can be as many as 2**32 -1 numbered match variables, on a 32-bit compiled Perl binary.

set DNS 8.8.4.4 and run emulator -avd react-native-device -dns-server 8.8.4.4

this work for me

An ftl file could just have a series of html tags just as a JSP page or it can have freemarker template coding for representing the objects passed on from a controller java file.
But, its actual ability is to combine the contents of a java class and view/client side stuff(html/ JQuery/ javascript etc). It is quite similar to velocity. You could map a method or object of a class to a freemarker (.ftl) page and use it as if it is a variable or a functionality created in the very page.

What about a non-relational (NoSQL) database such as Amazon's SimpleDB, Tokio Cabinet, etc? I've heard that Google, Facebook, LinkedIn are using these to store their huge datasets.

Can you tell us if your data is structured, if your schema is fixed, if you need easy replicability, if access times are important, etc?

The only thing that appears to work is to set flex-wrap: wrap; on the container and them somehow make the child you want to break out after to fill the full width, so width: 100%; should work.

If, however, you can't stretch the element to 100% (for example, if it's an <img>), you can apply a margin to it, like width: 50px; margin-right: calc(100% - 50px).

Basically, you should include the class' header file in the code where you want to use the class in the shared library. Then, when you link, use the '-l' flag to link your code with the shared library. Of course, this requires the .so to be where the OS can find it. See 3.5. Installing and Using a Shared Library

Using dlsym is for when you don't know at compile time which library you want to use. That doesn't sound like it's the case here. Maybe the confusion is that Windows calls the dynamically loaded libraries whether you do the linking at compile or run-time (with analogous methods)? If so, then you can think of dlsym as the equivalent of LoadLibrary.

If you really do need to dynamically load the libraries (i.e., they're plug-ins), then this FAQ should help.

Once the file object is iterated, it is exausted.

>>> f = open('1.txt', 'w')
>>> f.write('1\n2\n3\n')
>>> f.close()
>>> f = open('1.txt', 'r')
>>> for line in f: print line
...
1

# exausted, another iteration does not produce anything.
>>> for line in f: print line
...
>>>

Use file.seek (or close/open the file) to rewind the file:

>>> f.seek(0)
>>> for line in f: print line
...

If you open your resource file and change the access modifier to public or internal it will generate a class from your resource file which allows you to create strongly typed resource references.

Which means you can do something like this instead (using C# 6.0). Then you dont have to remember if firstname was lowercased or camelcased. And you can see if other properties use the same resource value with a find all references.

[Display(Name = nameof(PropertyNames.FirstName), ResourceType = typeof(PropertyNames))]
public string FirstName { get; set; }

Here is a full example on how to transform your date in different types:

Date date = Calendar.getInstance().getTime();

    // Display a date in day, month, year format
    DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
    String today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with day name in a short format
    formatter = new SimpleDateFormat("EEE, dd/MM/yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with a short day and month name
    formatter = new SimpleDateFormat("EEE, dd MMM yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Formatting date with full day and month name and show time up to
    // milliseconds with AM/PM
    formatter = new SimpleDateFormat("EEEE, dd MMMM yyyy, hh:mm:ss.SSS a");
    today = formatter.format(date);
    System.out.println("Today : " + today);

Sometime floats brake the vertical align, is better to avoid them.

The 'set Username="Username" ' is a temporary override that only exists as long as the cmd windows is still up, once it is killed off, the variable loses value. So i think the

System.getProperty("user.name");

is still a short and precise code to use.

Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?

Here is how I have done it in Kotlin.

1. Inject room db in the activity using DI (Koin).

    private val appDB: AppDB by inject()
   

2. Then you can simply call clearAllTables()

private fun clearRoomDB() {
    GlobalScope.launch {
        appDB.clearAllTables()
        preferences.put(PreferenceConstants.IS_UPLOADCATEGORIES_SAVED_TO_DB, false)
        preferences.put(PreferenceConstants.IS_MEMBERHANDBOOK_SAVED_TO_DB, false)
    }
}

PHP will work only on the .php file extension.

If you are on Apache you can also set, in your httpd.conf file, the extensions for PHP. You'll have to find the line:

AddType application/x-httpd-php .php .html
                                     ^^^^^

and add how many extensions, that should be read with the PHP interpreter, as you want.

You can use Case expression for returning a boolean in your select query like below.

@Query("SELECT CASE WHEN count(e) > 0 THEN true ELSE false END FROM MyEntity e where e.my_column = ?1")
