I had the same issue as described above the solutions given above are correct, the set up I have is as follows 1) Angularjs for the Client 2) Beego framework for GO server

Please following these points 1) CORS settings must be enabled only on GO server 2) Do NOT add any type of headers in angularJS except for this

.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }])

In you GO server add the CORS settings before the request starts to get processed so that the preflight request receives a 200 OK after which the the OPTIONS method will get converted to GET,POST,PUT or what ever is your request type.

a better sshpass alternative is: passh https://github.com/clarkwang/passh

Login to a remote server

 $ passh -p password ssh user@host

Run a command on remote server

 $ passh -p password ssh user@host date

other methods to pass the password

-p The password (Default: `password')

-p env: Read password from env var

-p file: Read password from file

here I explained why it is better than sshpass, and other solutions.

for Google Maps v3, you need to trigger the resize event differently:

google.maps.event.trigger(map, "resize");

See the documentation for the resize event (you'll need to search for the word 'resize'): http://code.google.com/apis/maps/documentation/v3/reference.html#event

Update

This answer has been here a long time, so a little demo might be worthwhile & although it uses jQuery, there's no real need to do so.

$(function() {
  var mapOptions = {
    zoom: 8,
    center: new google.maps.LatLng(-34.397, 150.644)
  };
  var map = new google.maps.Map($("#map-canvas")[0], mapOptions);

  // listen for the window resize event & trigger Google Maps to update too
  $(window).resize(function() {
    // (the 'map' here is the result of the created 'var map = ...' above)
    google.maps.event.trigger(map, "resize");
  });
});

html,
body {
  height: 100%;
}
#map-canvas {
  min-width: 200px;
  width: 50%;
  min-height: 200px;
  height: 80%;
  border: 1px solid blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&dummy=.js"></script>
Google Maps resize demo
<div id="map-canvas"></div>

UPDATE 2018-05-22

With a new renderer release in version 3.32 of Maps JavaScript API the resize event is no longer a part of Map class.

The documentation states

When the map is resized, the map center is fixed

• The full-screen control now preserves center.

• There is no longer any need to trigger the resize event manually.

source: https://developers.google.com/maps/documentation/javascript/new-renderer

google.maps.event.trigger(map, "resize"); doesn't have any effect starting from version 3.32

Second approach lets the compiler produce more optimized code, because when address of a variable is passed to a function, the compiler cannot keep its value in register(s) during subsequent calls to other functions. The completion code usually is used only once, just after the call, whereas "real" data returned from the call may be used more often

I'd like Grommit answer, except it require dupe values. I found solution where it may appear once: http://forums.devshed.com/showpost.php?p=1182653&postcount=2

MERGE INTO KBS.NUFUS_MUHTARLIK B

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

A dirty fix: Add $(VC_IncludePath);$(WindowsSDK_IncludePath); into project Properties / C/C++ / General / Additional include directories

Try to use this

parseFloat().toFixed(2)

One way is:

select table.* 
from table
join 
(
    select ID, max(Date) as max_dt 
    from table
    group by ID
) t
on table.ID= t.ID and table.Date = t.max_dt 

Note that if you have multiple equally higher dates for same ID, then you will get all those rows in result

Essentially console.log() allows you to output variables in your javascript debugger of choice instead of flashing an alert() every time you want to inspect something... additionally, for more complex objects it will give you a tree view to inspect the object further instead of having to convert elements to strings like an alert().

In iOS7 I needed the logic to return the correct height for the tableview:heightForRowAtIndexPath method, but the sizeWithAttributes always returns the same height regardless of the string length because it doesn't know that it is going to be put in a fixed width table cell. I found this works great for me and calculates the correct height taking in consideration the width for the table cell! This is based on Mr. T's answer above.

NSString *text = @"The text that I want to wrap in a table cell."

CGFloat width = tableView.frame.size.width - 15 - 30 - 15;  //tableView width - left border width - accessory indicator - right border width
UIFont *font = [UIFont systemFontOfSize:17];
NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text attributes:@{NSFontAttributeName: font}];
CGRect rect = [attributedText boundingRectWithSize:(CGSize){width, CGFLOAT_MAX}
                                           options:NSStringDrawingUsesLineFragmentOrigin
                                           context:nil];
CGSize size = rect.size;
size.height = ceilf(size.height);
size.width  = ceilf(size.width);
return size.height + 15;  //Add a little more padding for big thumbs and the detailText label

$('input[type=text], textarea').css({width: '90%'});

That uses standard CSS selectors, jQuery also has a set of pseudo-selector filters for various form elements, for example:

$(':text').css({width: '90%'});

will match all <input type="text"> elements. See Selectors documentation for more info.

I installed webapi with it via the helppages nuget package. That package replaced most of the asp.net mvc 4 binaries with beta versions which didn't work well together with the rest of the project. Fix was to restore the original mvc 4 dll's and all was good.

When accessing the field value, pass the instance rather than null.

Why not use code generation here? Eclipse, for example, will generate a reasoble toString implementation for you.

Use this JavaScript.

$(":input").inputmask();
$("#phone").inputmask({"mask": "(999) 999-9999"});

You can use this :

SELECT attname 
FROM pg_attribute,pg_class 
WHERE attrelid=pg_class.oid 
AND relname='TableName' 
AND attstattarget <>0; 

You're trying to use key functions with lambda functions.

Python and other languages like C# or F# use lambda functions.

Also, when it comes to key functions and according to the documentation

Both list.sort() and sorted() have a key parameter to specify a function to be called on each list element prior to making comparisons.

...

The value of the key parameter should be a function that takes a single argument and returns a key to use for sorting purposes. This technique is fast because the key function is called exactly once for each input record.

So, key functions have a parameter key and it can indeed receive a lambda function.

In Real Python there's a nice example of its usage. Let's say you have the following list

ids = ['id1', 'id100', 'id2', 'id22', 'id3', 'id30']

and want to sort through its "integers". Then, you'd do something like

sorted_ids = sorted(ids, key=lambda x: int(x[2:])) # Integer sort

and printing it would give

['id1', 'id2', 'id3', 'id22', 'id30', 'id100']

In your particular case, you're only missing to write key= before lambda. So, you'd want to use the following

a = sorted(a, key=lambda x: x.modified, reverse=True)

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

strcpy is only for C strings. For std::string you copy it like any C++ object.

std::string a = "text";
std::string b = a; // copy a into b

If you want to concatenate strings you can use the + operator:

std::string a = "text";
std::string b = "image";
a = a + b; // or a += b;

You can even do many at once:

std::string c = a + " " + b + "hello";

Although "hello" + " world" doesn't work as you might expect. You need an explicit std::string to be in there: std::string("Hello") + "world"

Try running the script explicitly using bash command rather than just executing it as executable.

Just want to contribute an alternative to loops...also addressing gaps in keys...

In my case I wanted to keep sequential array keys when the operation was complete (not just odd numbers, which is what I was staring at. Setting up code to look just for odd keys seemed fragile to me and not future-friendly.)

I was looking for something more like this: http://gotofritz.net/blog/howto/removing-empty-array-elements-php/

The combination of array_filter and array_slice does the trick.

$example = array_filter($example); $example = array_slice($example,0);

No idea on efficiencies or benchmarks but it works.

Here is how you define a react onClick event handler, which was answering the question title... using es6 syntax

import React, { Component } from 'react';

export default class Test extends Component {
  handleClick(e) {
    e.preventDefault()
    console.log(e.target)
  }

  render() {
    return (
      <a href='#' onClick={e => this.handleClick(e)}>click me</a>
    )
  }
}

HTML

<input id="fileInput" name="file" type="file" class="ng-hide" multiple>
<md-button id="uploadButton" class="md-raised md-primary"> Choose Files </md-button>

CONTROLLER

    var link = function (scope, element, attrs) {
    const input = element.find('#fileInput');
    const button = element.find('#uploadButton');

    if (input.length && button.length) {
        button.click((e) => input.click());
    }
}

Worked for me.

So it sounds like the bad commit was incorporated in a merge commit at some point. Has your merge commit been pulled yet? If yes, then you'll want to use git revert; you'll have to grit your teeth and work through the conflicts. If no, then you could conceivably either rebase or revert, but you can do so before the merge commit, then redo the merge.

There's not much help we can give you for the first case, really. After trying the revert, and finding that the automatic one failed, you have to examine the conflicts and fix them appropriately. This is exactly the same process as fixing merge conflicts; you can use git status to see where the conflicts are, edit the unmerged files, find the conflicted hunks, figure out how to resolve them, add the conflicted files, and finally commit. If you use git commit by itself (no -m <message>), the message that pops up in your editor should be the template message created by git revert; you can add a note about how you fixed the conflicts, then save and quit to commit.

For the second case, fixing the problem before your merge, there are two subcases, depending on whether you've done more work since the merge. If you haven't, you can simply git reset --hard HEAD^ to knock off the merge, do the revert, then redo the merge. But I'm guessing you have. So, you'll end up doing something like this:

• create a temporary branch just before the merge, and check it out
• do the revert (or use git rebase -i <something before the bad commit> <temporary branch> to remove the bad commit)
• redo the merge
• rebase your subsequent work back on: git rebase --onto <temporary branch> <old merge commit> <real branch>
• remove the temporary branch

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

You link to a local file the same way you link to local images. Here is an example to link to file start_caQtDM_7id.sh in the same directory as the markdown source:

![start_caQtDM_7id.sh](./start_caQtDM_7id.sh) 

You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink

Assuming you have foo.conf in sites-available

Try

cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l

Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf

Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.

If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.

ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf

Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:

lrwxrwxrwx 1 root root  26 Jun 24 21:06 000-default -> ../sites-available/default

See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).

Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.

As a quick and dirty solution leveraging existing infrastructure, you can wrap your uglyPrintedMap into a java.util.HashMap, then use toString().

uglyPrintedMap.toString(); // ugly
System.out.println( uglyPrintedMap ); // prints in an ugly manner

new HashMap<Object, Object>(jobDataMap).toString(); // pretty
System.out.println( new HashMap<Object, Object>(uglyPrintedMap) ); // prints in a pretty manner

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

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

Here's a general formula for creating thumbnails:

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

$thumb_width = 200;
$thumb_height = 150;

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

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

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

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

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

Haven't tested this but it should work.

EDIT

Now tested and working.

This means that there is a line which starts with a space, tab, or some other whitespace without having a target in front of it.

The absolutely best way: Just let your activity implement View.OnClickListener, and write your onClick method like this:

public void onClick(View v) {
    final int id = v.getId();
    switch (id) {
    case R.id.button1:
        // your code for button1 here
        break;
    case R.id.button2:
        // your code for button2 here
        break;
    // even more buttons here
    }
}

Then, in your XML layout file, you can set the click listeners directly using the attribute android:onClick:

<Button
    android:id="@+id/button1"
    android:onClick="onClick"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button 1" />

That is the most cleanest way of how to do it. I use it in all of mine projects today, as well.

Loading local JSON file

Use something like this

$.getJSON("../../data/file.json", function(json) {
    console.log(json); // this will show the info in firebug console 
    alert(json);
});

Most Previous answers were correct but here is the answer and example for Python 3.7. Yes, you can create an abstract class and method. Just as a reminder sometimes a class should define a method which logically belongs to a class, but that class cannot specify how to implement the method. For example, in the below Parents and Babies classes they both eat but the implementation will be different for each because babies and parents eat a different kind of food and the number of times they eat is different. So, eat method subclasses overrides AbstractClass.eat.

from abc import ABC, abstractmethod

class AbstractClass(ABC):

    def __init__(self, value):
        self.value = value
        super().__init__()

    @abstractmethod
    def eat(self):
        pass

class Parents(AbstractClass):
    def eat(self):
        return "eat solid food "+ str(self.value) + " times each day"

class Babies(AbstractClass):
    def eat(self):
        return "Milk only "+ str(self.value) + " times or more each day"

food = 3    
mom = Parents(food)
print("moms ----------")
print(mom.eat())

infant = Babies(food)
print("infants ----------")
print(infant.eat())

OUTPUT:

moms ----------
eat solid food 3 times each day
infants ----------
Milk only 3 times or more each day

If you're using the HTML5 Fetch API to make POST requests as a logged in user and getting Forbidden (CSRF cookie not set.), it could be because by default fetch does not include session cookies, resulting in Django thinking you're a different user than the one who loaded the page.

You can include the session token by passing the option credentials: 'include' to fetch:

var csrftoken = getCookie('csrftoken');
var headers = new Headers();
headers.append('X-CSRFToken', csrftoken);
fetch('/api/upload', {
    method: 'POST',
    body: payload,
    headers: headers,
    credentials: 'include'
})

The function is max. To obtain the first maximum value you should do

[val, idx] = max(a);

val is the maximum value and idx is its index.

Run -> Edit configurations -> Select your build configuration -> JRE - change Default to one of actual JDK paths

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

For other such DOM traversal queries, check out the documentation on traversing the DOM.

Here's a simpler explanation:

You're correct that whether you use notify() or notifyAll(), the immediate result is that exactly one other thread will acquire the monitor and begin executing. (Assuming some threads were in fact blocked on wait() for this object, other unrelated threads aren't soaking up all available cores, etc.) The impact comes later.

Suppose thread A, B, and C were waiting on this object, and thread A gets the monitor. The difference lies in what happens once A releases the monitor. If you used notify(), then B and C are still blocked in wait(): they are not waiting on the monitor, they are waiting to be notified. When A releases the monitor, B and C will still be sitting there, waiting for a notify().

If you used notifyAll(), then B and C have both advanced past the "wait for notification" state and are both waiting to acquire the monitor. When A releases the monitor, either B or C will acquire it (assuming no other threads are competing for that monitor) and begin executing.

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for GET method request:

var requestify = require('requestify');

requestify.get('http://example.com/api/resource')
  .then(function(response) {
      // Get the response body (JSON parsed or jQuery object for XMLs)
      response.getBody();
  }
);

I use two solutions for post-receive hook:

DEPLOY SOLUTION 1

#!/bin/bash 
#  /git-repo/hooks/post-receive - file content on server (chmod as 755 to be executed)
# DEPLOY SOLUTION 1 

    export GIT_DIR=/git/repo-bare.git

    echo "GIT BRANCH1:  $GIT_BRANCH1/"
    echo "GIT TARGET2:  $GIT_TARGET2/"
    echo "GIT BRANCH2:  $GIT_BRANCH2/"
    echo ""

        echo "Checking out to workdir: $GIT_WORK_TREE"; 

        git checkout -f $branch
    fi

    BRANCH_REGEX='^${GIT_BRANCH2}.*$'
    if [[ $branch =~ $BRANCH_REGEX ]] ; then
        export GIT_WORK_TREE=$GIT_TARGET2/.
        echo "Checking out branch: $branch";
        echo "Checking out to workdir: $GIT_WORK_TREE"; 

        git checkout -f $branch
    fi
done

DEPLOY SOLUTION 2

#!/bin/bash

        rm -rf $GIT_TEMP_DIR2
    fi
done

Both solutions are based on earlier solutions available in this thread.

Note, the BRANCH_REGEX='^${GIT_BRANCH1}.$' filters for the branch names matching "master" or "dev*" string, and deploys the work tree, if the pushed branch matches. This makes possible to deploy a dev version and master version to different places.

DEPLOY SOLUTION 1 removes only files, which are part of the repo, and was removed by a commit. It is faster than Deployment Solution 2.

DEPLOY SOLUTION 2 has the advantage, that it will remove any new files from the production directory, which was added on server side, no matter if it was added to the repo or not. It will be always clean dupe of the repo. It is slower than Deployment Solution 1.

Another way:

$c = 'A';
$chars = array($c);
while ($c < 'Z') $chars[] = ++$c;

Simple!!
one line:

 var res = test.Select(x => new string(x, 1)).ToArray();

Here is a solution for ES6 where you only want to keep the last item. This solution is functional and Airbnb style compliant.

const things = {
  thing: [
    { place: 'here', name: 'stuff' },
    { place: 'there', name: 'morestuff1' },
    { place: 'there', name: 'morestuff2' }, 
  ],
};

const removeDuplicates = (array, key) => {
  return array.reduce((arr, item) => {
    const removed = arr.filter(i => i[key] !== item[key]);
    return [...removed, item];
  }, []);
};

console.log(removeDuplicates(things.thing, 'place'));
// > [{ place: 'here', name: 'stuff' }, { place: 'there', name: 'morestuff2' }]

if you have

<span class="label label-default">New</span>

just add the style="font-size:XXpx;", ej.

<span class="label label-default" style="font-size:15px;">New</span>

You can use the simple mailto, see below for the simple markup.

<a href="mailto:[email protected]">Click here to mail</a>

Once clicked, it will open your Outlook or whatever email client you have set.

Create your annotation

  @Retention(RetentionPolicy.RUNTIME)
    public @interface AfterSpringLoadComplete {
    }

Create class

    public class PostProxyInvokerContextListener implements ApplicationListener<ContextRefreshedEvent> {

    @Autowired
    ConfigurableListableBeanFactory factory;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ApplicationContext context = event.getApplicationContext();
        String[] names = context.getBeanDefinitionNames();
        for (String name : names) {
            try {
                BeanDefinition definition = factory.getBeanDefinition(name);
                String originalClassName = definition.getBeanClassName();
                Class<?> originalClass = Class.forName(originalClassName);
                Method[] methods = originalClass.getMethods();
                for (Method method : methods) {
                    if (method.isAnnotationPresent(AfterSpringLoadComplete.class)){
                        Object bean = context.getBean(name);
                        Method currentMethod = bean.getClass().getMethod(method.getName(), method.getParameterTypes());
                        currentMethod.invoke(bean);
                    }
                }
            } catch (Exception ignored) {
            }
        }
    }
}

Register this class by @Component annotation or in xml

<bean class="ua.adeptius.PostProxyInvokerContextListener"/>

and use annotation where you wan on any method that you want to run after context initialized, like:

   @AfterSpringLoadComplete
    public void init() {}

The value attribute of a checkbox is what you set by:

<input type='checkbox' name='test' value='1'>

So when someone checks that box, the server receives a variable named test with a value of 1 - what you want to check for is not the value of it (which will never change, whether it is checked or not) but the checked status of the checkbox.

So, if you replace this code:

if (arrChecks[i].value == "on") 
{
    arrChecks[i].checked = 1;
} else {
    arrChecks[i].checked = 0;
}

With this:

arrChecks[i].checked = !arrChecks[i].checked;

It should work. You should use true and false instead of 0 and 1 for this.

open wp-config.php file and add the following line:

define('FS_METHOD', 'direct');

this is working for me ...Thanks

function convertTo24Hour(time) {
    time = time.toUpperCase();
    var hours = parseInt(time.substr(0, 2));
    if(time.indexOf('AM') != -1 && hours == 12) {
        time = time.replace('12', '0');
    }
    if(time.indexOf('PM')  != -1 && hours < 12) {
        time = time.replace(hours, (hours + 12));
    }
    return time.replace(/(AM|PM)/, '');
}

Cut can take several ranges in -f:

Columns up to 4 and from 7 onwards:

cut -f -4,7-

or for fields 1,2,5,6 and from 10 onwards:

cut -f 1,2,5,6,10-

etc

Use a duplicated double quote.

@"this ""word"" is escaped";

outputs:

this "word" is escaped

Add this before you connect to a URL behind a proxy.

System.getProperties().put("http.proxyHost", "someProxyURL");
System.getProperties().put("http.proxyPort", "someProxyPort");
System.getProperties().put("http.proxyUser", "someUserName");
System.getProperties().put("http.proxyPassword", "somePassword");

One you convert your image to gray-scale you cannot got back. You have gone from three channel to one, when you try to go back all three numbers will be the same. So the short answer is no you cannot go back. The reason your backtorgb function this throwing that error is because it needs to be in the format:

CvtColor(input, output, CV_GRAY2BGR)

OpenCV use BGR not RGB, so if you fix the ordering it should work, though your image will still be gray.

I know this is an old thread, but there is a nice library to do this:

System Rules

Example from the docs:

public void MyTest {
    @Rule
    public final SystemOutRule systemOutRule = new SystemOutRule().enableLog();

    @Test
    public void overrideProperty() {
        System.out.print("hello world");
        assertEquals("hello world", systemOutRule.getLog());
    }
}

It will also allow you to trap System.exit(-1) and other things that a command line tool would need to be tested for.

There are several ways to do it:

The simple Way: a sentinel variable

n = L[0][0]
m = len(A)
found = False
for i in range(m):
   if found:
      break
   for j in range(m):
     if L[i][j] != n: 
       found = True
       break

Pros: easy to understand Cons: additional conditional statement for every loop

The hacky Way: raising an exception

n = L[0][0]
m = len(A)

try:
  for x in range(3):
    for z in range(3):
     if L[i][j] != n: 
       raise StopIteration
except StopIteration:
   pass

Pros: very straightforward Cons: you use Exception outside of their semantic

The clean Way: make a function

def is_different_value(l, elem, size):
  for x in range(size):
    for z in range(size):
     if l[i][j] != elem: 
       return True
  return False

if is_different_value(L, L[0][0], len(A)):
  print "Doh"

pros: much cleaner and still efficient cons: yet feels like C

The pythonic way: use iteration as it should be

def is_different_value(iterable):
  first = iterable[0][0]
  for l in iterable:
    for elem in l:
       if elem != first: 
          return True
  return False

if is_different_value(L):
  print "Doh"

pros: still clean and efficient cons: you reinvdent the wheel

The guru way: use any():

def is_different_value(iterable):
  first = iterable[0][0]
  return  any(any((cell != first for cell in col)) for elem in iterable)):

if is_different_value(L):
  print "Doh"

pros: you'll feel empowered with dark powers cons: people that will read you code may start to dislike you

These 2 will be feel same as first as both are used to say about a condition to filter data. Though we can use ‘having’ in place of ‘where’ in any case, there are instances when we can’t use ‘where’ instead of ‘having’. This is because in a select query, ‘where’ filters data before ‘select’ while ‘having’ filter data after ‘select’. So, when we use alias names that are not actually in the database, ‘where’ can’t identify them but ‘having’ can.

Ex: let the table Student contain student_id,name, birthday,address.Assume birthday is of type date.

SELECT * FROM Student WHERE YEAR(birthday)>1993; /*this will work as birthday is in database.if we use having in place of where too this will work*/

SELECT student_id,(YEAR(CurDate())-YEAR(birthday)) AS Age FROM Student HAVING Age>20; 
/*this will not work if we use ‘where’ here, ‘where’ don’t know about age as age is defined in select part.*/

You can create the state in the ParentComponent using useState and pass down the setIsParentData function as prop into the ChildComponent.

In the ChildComponent, update the data using the received function through prop to send the data back to ParentComponent.

I use this technique especially when my code in the ParentComponent is getting too long, therefore I will create child components from the ParentComponent. Typically, it will be only 1 level down and using useContext or redux seems overkill in order to share states between components.

ParentComponent.js

import React, { useState } from 'react';
import ChildComponent from './ChildComponent';

export function ParentComponent(){
  const [isParentData, setIsParentData] = useState(True);

  return (
    <p>is this a parent data?: {isParentData}</p>
    <ChildComponent toChild={isParentData} sendToParent={setIsParentData} />
  );
}

ChildComponent.js

import React from 'react';

export function ChildComponent(props){

  return (
    <button onClick={() => {props.sendToParent(False)}}>Update</button>
    <p>The state of isParentData is {props.toChild}</p>
  );
};

There is no such thing as the "last" row in a table, as an Oracle table has no concept of order.

However, assuming that you wanted to find the last inserted primary key and that this primary key is an incrementing number, you could do something like this:

select *
  from ( select a.*, max(pk) over () as max_pk
           from my_table a
                )
 where pk = max_pk

If you have the date that each row was created this would become, if the column is named created:

select *
  from ( select a.*, max(created) over () as max_created
           from my_table a
                )
 where created = max_created

Alternatively, you can use an aggregate query, for example:

select *
  from my_table
 where pk = ( select max(pk) from my_table )

Here's a little SQL Fiddle to demonstrate.

If I understand correctly, you want to have one class implement multiple of those interfaces with different input/output parameters? This will not work in Java, because the generics are implemented via erasure.

The problem with the Java generics is that the generics are in fact nothing but compiler magic. At runtime, the classes do not keep any information about the types used for generic stuff (class type parameters, method type parameters, interface type parameters). Therefore, even though you could have overloads of specific methods, you cannot bind those to multiple interface implementations which differ in their generic type parameters only.

In general, I can see why you think that this code has a smell. However, in order to provide you with a better solution, it would be necessary to know a little more about your requirements. Why do you want to use a generic interface in the first place?

I just found an elegant way:

Convert.ChangeType("2020-12-31", typeof(DateTime));

Convert.ChangeType("2020/12/31", typeof(DateTime));

Convert.ChangeType("2020-01-01 16:00:30", typeof(DateTime));

Convert.ChangeType("2020/12/31 16:00:30", typeof(DateTime), System.Globalization.CultureInfo.GetCultureInfo("en-GB"));

Convert.ChangeType("11/?????/1437", typeof(DateTime), System.Globalization.CultureInfo.GetCultureInfo("ar-SA"));

Convert.ChangeType("2020-02-11T16:54:51.466+03:00", typeof(DateTime)); // format: "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzz"

Or you can try the same but without listeners. On your button XML definition:

android:onClick="ButtonOnClick"

And in your code define the method ButtonOnClick:

public void ButtonOnClick(View v) {
    switch (v.getId()) {
      case R.id.button1:
        doSomething1();
        break;
      case R.id.button2:
        doSomething2();
        break;
      }
}

You can exclude like this, the regex 'or' symbol, assuming a file you want doesn't have the same name as a folder you're excluding.

$exclude = 'dir1|dir2|dir3'
ls -r | where { $_.fullname -notmatch $exclude }

ls -r -dir | where fullname -notmatch 'dir1|dir2|dir3'

For PHP code:

<?php
error_reporting(E_ALL & ~E_NOTICE);

For php.ini config:

error_reporting = E_ALL & ~E_NOTICE

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

I'm using the following function for that; it's an adaptation from one of the man entries in the fputscsv comments. And you'll probably want to flatten that array; not sure what happens if you pass in a multi-dimensional one.

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

If you are using IIS server by chance. you can set below headers in the HTTP request headers option.

Access-Control-Allow-Origin:*
Access-Control-Allow-Methods: 'HEAD, GET, POST, PUT, PATCH, DELETE'
Access-Control-Allow-Headers: 'Origin, Content-Type, X-Auth-Token';

with this all post, get etc., will work fine.

Got the solution and it's working fine. Set the environment variables as:

• CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59 (path where your Apache Tomcat is)
• JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25; (path where your JDK is)
• JRE_Home=C:\Program Files\Java\jre1.8.0_25; (path where your JRE is)
• CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib

I know that this is super-duper old, but on the off chance that someone comes looking for this, as of Visual Basic 14, Vb supports interpolation. Sooooo cool!

Example:

SQLQueryString = $"
   Insert into Employee values( 
       {txtEmployeeNo}, 
       {txtContractsStartDate},
       {txtSeatNo},
       {txtFloor},
       {txtLeaves}
)"

It works. Documentation Here

Edit: After writing this, I realized that the OP was talking about VBA. This will not work in VBA!!! However, I will leave this up here, because as someone new to VB, I stumbled upon this question looking for a solution to just this problem in VB.net. If this helps someone else, great.

document.getElementById('one').innerText;
alert(content);

It does not print the value; But, if done this way

document.getElementById('one').value;
alert(content);

Recently I found very easy and interesting function to print legend outside of the plot area where you want.

Make the outer margin at the right side of the plot.

par(xpd=T, mar=par()$mar+c(0,0,0,5))

Create a plot

plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

Add legend and just use locator(1) function as like below. Then you have to just click where you want after load following script.

legend(locator(1),c("group A", "group B"), pch = c(1,2), lty = c(1,2))

Try it

Windows 10

This is basically @lengxuehx's answer, but updated for Win 10, and it assumes your bash installation is from Git Bash for Windows from git's official downloads.

cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

I ended up using this after I lost my context-menu items for Git Bash as my command to run from the registry settings. In case you're curious about that, I did this:

1. Create a new key called Bash in the shell key at HKEY_CLASSES_ROOT\Directory\Background\shell
2. Add a string value to Icon (not a new key!) that is the full path to your git-bash.exe, including the git-bash.exe part. You might need to wrap this in quotes.
3. Edit the default value of Bash to the text you want to use in the context menu
4. Add a sub-key to Bash called command
5. Modify command's default value to cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

Then you should be able to close the registry and start using Git Bash from anywhere that's a real directory. For example, This PC is not a real directory.

IMO using the C++ reference for std::string is a quick and short local optimization, while using passing by value could be (or not) a better global optimization.

So the answer is: it depends on circumstances:

1. If you write all the code from the outside to the inside functions, you know what the code does, you can use the reference const std::string &.
2. If you write the library code or use heavily library code where strings are passed, you likely gain more in global sense by trusting std::string copy constructor behavior.

I would use TreeMap, which implements SortedMap. It is designed exactly for that.

Example:

Map<Integer, String> map = new TreeMap<Integer, String>();

// Add Items to the TreeMap
map.put(1, "One");
map.put(2, "Two");
map.put(3, "Three");

// Iterate over them
for (Map.Entry<Integer, String> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " => " + entry.getValue());
}

See the Java tutorial page for SortedMap.
And here a list of tutorials related to TreeMap.

If you are trying to trigger an event on the anchor, then the code you have will work.

$(document).ready(function() {
  $('a#titleee').trigger('click');
});

OR

$(document).ready(function() {
  $('#titleee li a[href="#inline"]').click();
});

OR

$(document).ready(function() {
  $('ul#titleee li a[href="#inline"]').click();
});

My trick is using an attribute selector. Attributes are easier to set up by javascript.

css

.class{ /*normal css... */}
.class[special]:after{ content: 'what you want'}

javascript

  function setSpecial(id){ document.getElementById(id).setAttribute('special', '1'); }

html

<element id='x' onclick="setSpecial(this.id)"> ...  

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.
debug1: connect to address 173.194.43.20 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

Another usage of colon in JavaScript is to rename a variable, that is:

const person = { 
    nickNameThatIUseOnStackOverflow: "schlingel",
    age: 30,
    firstName: "John"
};
let { nickNameThatIUseOnStackOverflow: nick } = person; // I take nickNameThatIUseOnStackOverflow but want to refer it as "nick" from now on.
nick = "schling";

This is useful if you use a third party library that returns values having awkward / long variable names that you want to rename in your code.

I think the only way of doing this in SQL-Server 2008R2 is to use a correlated subquery, or an outer apply:

SELECT  datekey,
        COALESCE(RunningTotal, 0) AS RunningTotal,
        COALESCE(RunningCount, 0) AS RunningCount,
        COALESCE(RunningDistinctCount, 0) AS RunningDistinctCount
FROM    document
        OUTER APPLY
        (   SELECT  SUM(Amount) AS RunningTotal,
                    COUNT(1) AS RunningCount,
                    COUNT(DISTINCT d2.dateKey) AS RunningDistinctCount
            FROM    Document d2
            WHERE   d2.DateKey <= document.DateKey
        ) rt;

This can be done in SQL-Server 2012 using the syntax you have suggested:

SELECT  datekey,
        SUM(Amount) OVER(ORDER BY DateKey) AS RunningTotal
FROM    document

However, use of DISTINCT is still not allowed, so if DISTINCT is required and/or if upgrading isn't an option then I think OUTER APPLY is your best option

See Java tools documentation for:

• java command¹/javaw command²

1. The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.
2. The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear.

• javaws command, the "Java Web Start command"

The javaws command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP). Java Web Start launches Java applications/applets hosted on a network.

If a JNLP file is specified, javaws will launch the Java application/applet specified in the JNLP file.

The javaws launcher has a set of options that are supported in the current release. However, the options may be removed in a future release.

See also JDK 9 Release Notes Deprecated APIs, Features, and Options:

Java Deployment Technologies are deprecated and will be removed in a future release
Java Applet and WebStart functionality, including the Applet API, the Java plug-in, the Java Applet Viewer, JNLP and Java Web Start, including the javaws tool, are all deprecated in JDK 9 and will be removed in a future release.

Linked list is guaranteed to act in sequential order.

From the documentation

An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.

iterator() Returns an iterator over the elements in this list in proper sequence.

if " isn't working then try " instead.

In tables I have used \footnotetext.

ip address can be from 0.0.0.0 to 255.255.255.255

(((0|1)?[0-9][0-9]?|2[0-4][0-9]|25[0-5])[.]){3}((0|1)?[0-9][0-9]?|2[0-4][0-9]|25[0-5])$

(0|1)?[0-9][0-9]? - checking value from 0 to 199
2[0-4][0-9]- checking value from 200 to 249
25[0-5]- checking value from 250 to 255
[.] --> represent verify . character 
{3} --> will match exactly 3
$ --> end of string

It's more simple than you think. Try this:

egrep -wo 'th.[a-z]*' filename.txt #### (Case Sensitive)

egrep -iwo 'th.[a-z]*' filename.txt  ### (Case Insensitive)

Where,

 egrep: Grep will work with extended regular expression.
 w    : Matches only word/words instead of substring.
 o    : Display only matched pattern instead of whole line.
 i    : If u want to ignore case sensitivity.

frameLayout.addView(yourView); <----- if you are getting error on this line remove view from it's parent first

if (yourView.getParent() != null)

((ViewGroup) yourView.getParent()).removeView(yourView); frameLayout.addView(yourView); (Add view to layout)

Here's what worked for me:

background-size: auto 100%;

<script type="text/javascript"> 
$(document).ready(function() {
  if (!$("#mySelect option:selected").length)
   $("#mySelect").val( 3 );

});
</script>

If you need to create the regexp from a variable, this is a much better way to do it: https://stackoverflow.com/a/10728069/309514

You can then do something like:

var string = "SomeStringToFind";
var regex = new RegExp(["^", string, "$"].join(""), "i");
// Creates a regex of: /^SomeStringToFind$/i
db.stuff.find( { foo: regex } );

This has the benefit be being more programmatic or you can get a performance boost by compiling it ahead of time if you're reusing it a lot.

If you're on OSX you can also find it your keychain. Your developer and distribution certificates have your Team ID in them.

Applications -> Utilities -> Keychain Access.

Under the 'login' Keychain, go into the 'Certificates' category.

Scroll to find your development or distribution certificate. They will read:

iPhone Distribution: Team Name (certificate id)

or

iPhone Developer: Team Name (certificate id)

Simply double-click on the item, and the

"Organizational Unit"

is the "Team ID"

Note that this is the only way to find your

"Personal team" ID

You can not find the "Personal team" ID on the Apple web interface.

For example, if you are automating a build from say Unity, during development you'll want it to appear in Xcode as your "Personal team" - this is the only way to get that value.

We can prove it mathematically which is something I was missing in the above answers.

It can dramatically help you understand how to calculate any method. I recommend reading it from top to bottom to fully understand how to do it:

1. T(n) = T(n-1) + 1 It means that the time it takes for the method to finish is equal to the same method but with n-1 which is T(n-1) and we now add + 1 because it's the time it takes for the general operations to be completed (except T(n-1)). Now, we are going to find T(n-1) as follow: T(n-1) = T(n-1-1) + 1. It looks like we can now form a function that can give us some sort of repetition so we can fully understand. We will place the right side of T(n-1) = ... instead of T(n-1) inside the method T(n) = ... which will give us: T(n) = T(n-1-1) + 1 + 1 which is T(n) = T(n-2) + 2 or in other words we need to find our missing k: T(n) = T(n-k) + k. The next step is to take n-k and claim that n-k = 1 because at the end of the recursion it will take exactly O(1) when n<=0. From this simple equation we now know that k = n - 1. Let's place k in our final method: T(n) = T(n-k) + k which will give us: T(n) = 1 + n - 1 which is exactly n or O(n).
2. Is the same as 1. You can test it your self and see that you get O(n).
3. T(n) = T(n/5) + 1 as before, the time for this method to finish equals to the time the same method but with n/5 which is why it is bounded to T(n/5). Let's find T(n/5) like in 1: T(n/5) = T(n/5/5) + 1 which is T(n/5) = T(n/5^2) + 1. Let's place T(n/5) inside T(n) for the final calculation: T(n) = T(n/5^k) + k. Again as before, n/5^k = 1 which is n = 5^k which is exactly as asking what in power of 5, will give us n, the answer is log5n = k (log of base 5). Let's place our findings in T(n) = T(n/5^k) + k as follow: T(n) = 1 + logn which is O(logn)
4. T(n) = 2T(n-1) + 1 what we have here is basically the same as before but this time we are invoking the method recursively 2 times thus we multiple it by 2. Let's find T(n-1) = 2T(n-1-1) + 1 which is T(n-1) = 2T(n-2) + 1. Our next place as before, let's place our finding: T(n) = 2(2T(n-2)) + 1 + 1 which is T(n) = 2^2T(n-2) + 2 that gives us T(n) = 2^kT(n-k) + k. Let's find k by claiming that n-k = 1 which is k = n - 1. Let's place k as follow: T(n) = 2^(n-1) + n - 1 which is roughly O(2^n)
5. T(n) = T(n-5) + n + 1 It's almost the same as 4 but now we add n because we have one for loop. Let's find T(n-5) = T(n-5-5) + n + 1 which is T(n-5) = T(n - 2*5) + n + 1. Let's place it: T(n) = T(n-2*5) + n + n + 1 + 1) which is T(n) = T(n-2*5) + 2n + 2) and for the k: T(n) = T(n-k*5) + kn + k) again: n-5k = 1 which is n = 5k + 1 that is roughly n = k. This will give us: T(n) = T(0) + n^2 + n which is roughly O(n^2).

I now recommend reading the rest of the answers which now, will give you a better perspective. Good luck winning those big O's :)

This is a well-known nuisance when posting multiline commands in R. (You can get different behavior when you source() a script to when you copy-and-paste the lines, both with multiline and comments)

Rule: always put the dangling '+' at the end of a line so R knows the command is unfinished:

ggplot(...) + geom_whatever1(...) +
  geom_whatever2(...) +
  stat_whatever3(...) +
  geom_title(...) + scale_y_log10(...)

Don't put the dangling '+' at the start of the line, since that tickles the error:

Error in "+ geom_whatever2(...) invalid argument to unary operator"

And obviously don't put dangling '+' at both end and start since that's a syntax error.

So, learn a habit of being consistent: always put '+' at end-of-line.

cf. answer to "Split code over multiple lines in an R script"

Late response but you could just keep it simple and apply a CSS class to the htmlAttributes object.

<%= Html.ActionLink("Button Name", "Index", null, new { @class="classname" }) %>

and then create a class in your stylesheet

a.classname
{
    background: url(../Images/image.gif) no-repeat top left;
     display: block;
     width: 150px;
     height: 150px;
     text-indent: -9999px; /* hides the link text */
}

try this:

var span = document.getElementById("span");
span.style.fontSize = "25px";
span.innerHTML = "String";

If you want to run an unmodified python script so it imports libraries from a specific local directory you can set the PYTHONPATH environment variable - e.g. in bash:

export PYTHONPATH=/home/user/my_libs
python myscript.py

If you just want it to import from the current working directory use the . notation:

export PYTHONPATH=.
python myscript.py

eval(compile(myvar,'<str>','eval'))(myargs)

compile(...,'eval') allows only a single statement, so that there can't be arbitrary commands after a call, or there will be a SyntaxError. Then a tiny bit of validation can at least constrain the expression to something in your power, like testing for 'mypackage' to start.

It does exactly what the var does with a scope difference. Now it can not take the name var since that is already taken.

So it looks that it has taken the next best name which has a semantic in an interesting English language construct.

let myPet = 'dog';

In English it says "Let my pet be a dog"

I know I'm very late but for those who still have that problem, it can be solved easily. I use Qt 5.3 and it works fine. No need to create a function or all that.

int valueComboBox;
valueComboBox = comboBox->currentIndex();

and it works ! Hope it helps !

I decided to just build controls dictionaries. Harder to maintain, might run faster than the recursive FindControl().

protected void Page_Load(object sender, EventArgs e)
{
  this.BuildControlDics();
}

private void BuildControlDics()
{
  _Divs = new Dictionary<MyEnum, HtmlContainerControl>();
  _Divs.Add(MyEnum.One, this.divOne);
  _Divs.Add(MyEnum.Two, this.divTwo);
  _Divs.Add(MyEnum.Three, this.divThree);

}

And before I get down-thumbs for not answering the OP's question...

Q: Now, my question is that is there any other way/solution to find the nested control in ASP.NET? A: Yes, avoid the need to search for them in the first place. Why search for things you already know are there? Better to build a system allowing reference of known objects.

As eaon21 and monkey said, source map files basically turn minified code into its unminified version for debugging.

You can find the .map files here. Just add them into the same directory as the minified js files and it'll stop complaining. The reason they get fetched is the

/*
//@ sourceMappingURL=angular.min.js.map
*/

at the end of angular.min.js. If you don't want to add the .map files you can remove those lines and it'll stop the fetch attempt, but if you plan on debugging it's always good to keep the source maps linked.

You must ";" separator, CSV => Comma Separator Value

 ofstream Morison_File ("linear_wave_loading.csv");         //Opening file to print info to
    Morison_File << "'Time'; 'Force(N/m)' " << endl;          //Headings for file
    for (t = 0; t <= 20; t++) {
      u = sin(omega * t);
      du = cos(omega * t); 
      F = (0.5 * rho * C_d * D * u * fabs(u)) + rho * Area * C_m * du; 

      cout << "t = " << t << "\t\tF = " << F << endl;
      Morison_File << t << ";" << F;

    }

     Morison_File.close();

Instead of using pull-right class, it is better to use text-right class in the column, because pull-right creates problems sometimes while resizing the page.

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

My fork of fswatch provides the functionality of inotifywait -m with slightly less (no wait, more! I have a lot more troubles on Linux with inotifywait...) parse-friendly output.

It is an improvement upon the original fswatch because it sends out the actual path of the changed file over STDOUT rather than requiring you to provide a program that it forks.

It's been rock solid as the foundation of a series of scary bash scripts I use to automate stuff.

(this is off-topic) inotifywait on Linux, on the other hand, requires a lot of kludges on top of it and I still haven't figured out a good way to manage it, though I think something based on node.js might be the ticket.

Prior to PHP 5.4:

$myArray = [];

I hope my late answer can be of some help.
This will go to rails database console.

rails db

pretty print your query output

.headers on
.mode columns
(turn headers on and show database data in column mode )

Show the tables

.table

'.help' to see help.
Or use SQL statements like 'Select * from cars'

There may be 2 spaces after the text, please confirm. You can use LTRIM and RTRIM functions also right?

LTRIM(RTRIM(ProductAlternateKey))

Maybe the extra space isn't ordinary spaces (ASCII 32, soft space)? Maybe they are "hard space", ASCII 160?

ltrim(rtrim(replace(ProductAlternateKey, char(160), char(32))))

You can try the following code to convert the image to hex string

<?php
$image = 'sample.bmp';
$file = fopen($image, 'r') or die("Could not open $image");
while ($file && !feof($file)){
$chunk = fread($file, 1000000); # You can affect performance altering
this number. YMMV.
# This loop will be dog-slow, almost for sure...
# You could snag two or three bytes and shift/add them,
# but at 4 bytes, you violate the 7fffffff limit of dechex...
# You could maybe write a better dechex that would accept multiple bytes
# and use substr... Maybe.
for ($byte = 0; $byte < strlen($chunk); $byte++)){
echo dechex(ord($chunk[$byte]));
}
}
?>

Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!

import pandas as pd
import numpy as np

df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )

# Create an index list from the set of dates in both data frames
Index = list(set(list(df1.index) + list(df2.index)))
Index.sort()

df3 = pd.DataFrame({'df1': [df1.loc[Date, 'c'] if Date in df1.index else np.nan for Date in Index],\
                'df2': [df2.loc[Date, 'c'] if Date in df2.index else np.nan for Date in Index],},\
                index = Index)

df3

Some of the answers, while correct may be a little tricky to understand. Here is an example in layman's terms:

var users = ["Sam", "Ellie", "Bernie"];

function addUser(username, callback)
{
    setTimeout(function()
    {
        users.push(username);
        callback();
    }, 200);
}

function getUsers()
{
    setTimeout(function()
    {
        console.log(users);
    }, 100);
}

addUser("Jake", getUsers);

The callback means, "Jake" is always added to the users before displaying the list of users with console.log.

CHECKPOINT; 
GO 
DBCC DROPCLEANBUFFERS; 
GO

From the linked article:

If all of the performance testing is conducted in SQL Server the best approach may be to issue a CHECKPOINT and then issue the DBCC DROPCLEANBUFFERS command. Although the CHECKPOINT process is an automatic internal system process in SQL Server and occurs on a regular basis, it is important to issue this command to write all of the dirty pages for the current database to disk and clean the buffers. Then the DBCC DROPCLEANBUFFERS command can be executed to remove all buffers from the buffer pool.

The query either returned no rows or is erroneus, thus FALSE is returned. Change it to

if (!$dbc || mysqli_num_rows($dbc) == 0)

mysqli_num_rows:

Return Values

Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.

If you are sending a request through url from browser(like consuming webservice) without using html pages by default it will be GET because GET has/needs no body. if you want to make url as POST you need html/jsp pages and you have to mention in form tag as "method=post" beacause post will have body and data will be transferred in that body for security reasons. So you need a medium (like html page) to make a POST request. You cannot make an URL as POST manually unless you specify it as POST through some medium. For example in URL (http://example.com/details?name=john&phonenumber=445566)you have attached data(name, phone number) so server will identify it as a GET data because server is receiving data is through URL but not inside a request body

I'm assuming you have multiple markers that you wish to display on a google map.

The solution is two parts, one to create and populate an array containing all the details of the markers, then a second to loop through all entries in the array to create each marker.

Not know what environment you're using, it's a little difficult to provide specific help.

My best advice is to take a look at this article & accepted answer to understand the principals of creating a map with multiple markers: Display multiple markers on a map with their own info windows

Actually, the onclick events will NOT fire when the user uses the keyboard to change the selection in the select control. You might have to use a combination of onChange and onClick to get the behavior you're looking for.

The Vpointer is created at the time of object creation. vpointer wont exists before object creation. so there is no point of making the constructor as virtual.

I've found that UC Irvine has a great collection of python modules, pywin32 (win32api) being one of many listed there. I'm not sure how they do with keeping up with the latest versions of these modules but it hasn't let me down yet.

UC Irvine Python Extension Repository - http://www.lfd.uci.edu/~gohlke/pythonlibs

pywin32 module - http://www.lfd.uci.edu/~gohlke/pythonlibs/#pywin32

function myfunction() {
     if(a == 'stop') 
         return false;
}

return false; is much better than just return;

I strongly recommend BOUML which:

• is extremely fast (fastest UML tool ever created, check out benchmarks),
• has rock solid PHP import and export support (also supports C++, Java, Python)
• is multiplatform (Linux, Windows, other OSes),
• is full featured, impressively intensively developed (look at development history, it's hard to believe that such fast progress is possible).
• supports plugins, has modular architecture (this allows user contributions, looks like BOUML community is forming up)

There are two variants of CASE, and you're not using the one that you think you are.

What you're doing

CASE case_value
    WHEN when_value THEN statement_list
    [WHEN when_value THEN statement_list] ...
    [ELSE statement_list]
END CASE

Each condition is loosely equivalent to a if (case_value == when_value) (pseudo-code).

However, you've put an entire condition as when_value, leading to something like:

if (case_value == (case_value > 100))

Now, (case_value > 100) evaluates to FALSE, and is the only one of your conditions to do so. So, now you have:

if (case_value == FALSE)

FALSE converts to 0 and, through the resulting full expression if (case_value == 0) you can now see why the third condition fires.

What you're supposed to do

Drop the first course_enrollment_settings so that there's no case_value, causing MySQL to know that you intend to use the second variant of CASE:

CASE
    WHEN search_condition THEN statement_list
    [WHEN search_condition THEN statement_list] ...
    [ELSE statement_list]
END CASE

Now you can provide your full conditionals as search_condition.

Also, please read the documentation for features that you use.

StringBuilder is preferable IF you are doing multiple loops, or forks in your code pass... however, for PURE performance, if you can get away with a SINGLE string declaration, then that is much more performant.

For example:

string myString = "Some stuff" + var1 + " more stuff"
                  + var2 + " other stuff" .... etc... etc...;

is more performant than

StringBuilder sb = new StringBuilder();
sb.Append("Some Stuff");
sb.Append(var1);
sb.Append(" more stuff");
sb.Append(var2);
sb.Append("other stuff");
// etc.. etc.. etc..

In this case, StringBuild could be considered more maintainable, but is not more performant than the single string declaration.

9 times out of 10 though... use the string builder.

On a side note: string + var is also more performant that the string.Format approach (generally) that uses a StringBuilder internally (when in doubt... check reflector!)

Actually I think you may need to use if (value !== null || value !== undefined) because if you use if (value) you may also filter 0 or false values.

Consider these two functions:

const firstTest = value => {
    if (value) {
        console.log('passed');
    } else {
        console.log('failed');
    }
}
const secondTest = value => {
    if (value !== null && value !== undefined) {
        console.log('passed');
    } else {
        console.log('failed');
    }
}

firstTest(0);            // result: failed
secondTest(0);           // result: passed

firstTest(false);        // result: failed
secondTest(false);       // result: passed

firstTest('');           // result: failed
secondTest('');          // result: passed

firstTest(null);         // result: failed
secondTest(null);        // result: failed

firstTest(undefined);    // result: failed
secondTest(undefined);   // result: failed

In my situation, I just needed to check if the value is null and undefined and I did not want to filter 0 or false or '' values. so I used the second test, but you may need to filter them too which may cause you to use first test.

There is no standard assert in JavaScript itself. Perhaps you're using some library that provides one; for instance, if you're using Node.js, perhaps you're using the assertion module. (Browsers and other environments that offer a console implementing the Console API provide console.assert.)

The usual meaning of an assert function is to throw an error if the expression passed into the function is false; this is part of the general concept of assertion checking. Usually assertions (as they're called) are used only in "testing" or "debug" builds and stripped out of production code.

Suppose you had a function that was supposed to always accept a string. You'd want to know if someone called that function with something that wasn't a string (without having a type checking layer like TypeScript or Flow). So you might do:

assert(typeof argumentName === "string");

...where assert would throw an error if the condition were false.

A very simple version would look like this:

function assert(condition, message) {
    if (!condition) {
        throw message || "Assertion failed";
    }
}

Better yet, make use of the Error object, which has the advantage of collecting a stack trace and such:

function assert(condition, message) {
    if (!condition) {
        throw new Error(message || "Assertion failed");
    }
}

Use list comprehensions if you want a single line solution. The following code returns a list containing the url_string when it has the extensions .doc, .pdf and .xls or returns empty list when it doesn't contain the extension.

print [url_string for extension in extensionsToCheck if(extension in url_string)]

NOTE: This is only to check if it contains or not and is not useful when one wants to extract the exact word matching the extensions.

'SET' is forgotten

ALTER TABLE ONLY users ALTER COLUMN lang SET DEFAULT 'en_GB';

The following worked very well for me for this problem:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {

CGRect frame = [self.view frame];
frame.size.height =  frame.size.height - (kTableRowHeight * numberOfRowsInTable);

UIView *footerView = [[UIView alloc] initWithFrame:frame];
return footerView; }

Where kTableRowHeight is the height of my row cells and numberOfRowsInTable is the number of rows I had in the table.

Hope that helps,

Brenton.

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

From the docs:

The SimpleHTTPServer module has been merged into http.server in Python 3.0. The 2to3 tool will automatically adapt imports when converting your sources to 3.0.

So, your command is python -m http.server, or depending on your installation, it can be:

python3 -m http.server

Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
  dateFormat.format(startDate)+" and "+
  dateFormat.format(endDate)+" is "+
  diffDays+" days.");

This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:

start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
    start.add(Calendar.DAY_OF_MONTH, 1);
    diffDays++;
}
while (start.after(end)) {
    start.add(Calendar.DAY_OF_MONTH, -1);
    diffDays--;
}

O(1) always execute in the same time regardless of dataset n. An example of O(1) would be an ArrayList accessing its element with index.

O(n) also known as Linear Order, the performance will grow linearly and in direct proportion to the size of the input data. An example of O(n) would be an ArrayList insertion and deletion at random position. As each subsequent insertion/deletion at random position will cause the elements in the ArrayList to shift left right of its internal array in order to maintain its linear structure, not to mention about the creation of a new arrays and the copying of elements from the old to new array which takes up expensive processing time hence, detriment the performance.

Ran into this issue with Parallels and VS 2013. Command + Insert also fixed it in my setup, in addition to the accepted answer. On my Windows USB keyboard Command == WindowsKey.

If some users of the code have different language settings format might not work. Thus I use the following code that gives the time stamp in format "yyymmdd hhMMss" regardless of language.

Function TimeStamp()
Dim iNow
Dim d(1 To 6)
Dim i As Integer


iNow = Now
d(1) = Year(iNow)
d(2) = Month(iNow)
d(3) = Day(iNow)
d(4) = Hour(iNow)
d(5) = Minute(iNow)
d(6) = Second(iNow)

For i = 1 To 6
    If d(i) < 10 Then TimeStamp = TimeStamp & "0"
    TimeStamp = TimeStamp & d(i)
    If i = 3 Then TimeStamp = TimeStamp & " "
Next i

End Function

For local time in ISO8601 for SQL TIMESTAMP you could try:

var tzoffset = (new Date()).getTimezoneOffset() * 60000;
var localISOTime = (new Date(Date.now() - tzoffset))
  .toISOString()
  .slice(0, 19)
  .replace('T', ' ');
$('#mydatediv').val(localISOTime);

I needed to extract a few lines in a log file and this post was helpful in solving my issue, so i thought of adding it here. If someone needs to extract muliple lines, you can use the script to get the index of the a word matching that string (i'm searching for "Root") and extract content in all lines.

$File_content = Get-Content "Path of the text file"
$result = @()

foreach ($val in $File_content){
    $Index_No = $val.IndexOf("Root")
    $result += $val.substring($Index_No)
}

$result | Select-Object -Unique

Cheers..!

Errors like that are usually sent to the "standard error" stream, which you can pipe to a file or just make disappear on most commands:

grep pattern * -R -n 2>/dev/null

I think this should work:

#open file for reading
fn = input("Enter file to open: ")
try:
    fh = open(fn,'r')
except:
# if file does not exist, create it
    fh = open(fn,'w')

Also, you incorrectly wrote fh = open ( fh, "w") when the file you wanted open was fn

In Rails, the unit folder is meant to hold tests for your models, the functional folder is meant to hold tests for your controllers, and the integration folder is meant to hold tests that involve any number of controllers interacting. Fixtures are a way of organizing test data; they reside in the fixtures folder. The test_helper.rb file holds the default configuration for your tests. u can visit this.

I went ahead and downloaded the project from the link you provided: http://javapapers.com/android/android-chat-bubble/

Since this is an old tutorial, you simply need to upgrade the software, gradle, the android build tools and plugin.

Make sure you have the latest Gradle and Android Studio:

• https://www.gradle.org/
• http://tools.android.com/tech-docs/new-build-system/version-compatibility

build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

app/build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName '1.0'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.1'
}

Then run gradle:

gradle installDebug

Converting millis to datetime (UTC):

import datetime
time_in_millis = 1596542285000
dt = datetime.datetime.fromtimestamp(time_in_millis / 1000.0, tz=datetime.timezone.utc)

Converting datetime to string following the RFC3339 standard (used by Open API specification):

from rfc3339 import rfc3339
converted_to_str = rfc3339(dt, utc=True, use_system_timezone=False)
# 2020-08-04T11:58:05Z

See http://ruby-doc.org/core/classes/Range.html#M000695 for the full API.

Basically you use the step() method. For example:

(10..100).step(10) do |n|
    # n = 10
    # n = 20
    # n = 30
    # ...
end

Map is an interface in Java. And HashMap is an implementation of that interface (i.e. provides all of the methods specified in the interface).

http://subclipse.tigris.org/wiki/PluginFAQ#head-d507c29676491f4419997a76735feb6ef0aa8cf8:

Usernames and passwords

Subclipse does not collect or store username and password credentials when defining a repository. This is because the JavaHL and SVNKit client adapters are intelligent enough to prompt you for this information when they need to -- including when your password has changed.

You can also allow the adapter to cache this information and a common question is how do you delete this cached information so that you can be prompted again? We have an open request to have an API added to JavaHL so that we could provide a UI to do this. Currently, you have to manually delete the cache. The location of the cache varies based on the client adapter used.

JavaHL caches the information in the same location as the command line client -- in the Subversion runtime configuration area. On Windows this is located in %APPDATA%\Subversion\auth. On Linux and OSX it is located in ~/.subversion/auth. Just find and delete the file with the cached information.

SVNKit caches information in the Eclipse keyring. By default this is a file named .keyring that is stored in the root of the Eclipse configuration folder. Both of these values can be overriden with command line options. To clear the cache, you have to delete the file. Eclipse will create a new empty keyring when you restart

In short you can try this....

<div data-role="page" style="background:url('backgrnd.png'); background-repeat: no-repeat; background-size: 100% 100%;" >

Where I have used few css and js...

<link rel="stylesheet" href="css/jquery.mobile-1.0.1.min.css" />
<script src="js/jquery-1.7.1.min.js"></script>
<script src="js/jquery.mobile-1.0.1.min.js"></script>

And it is working fine for me.

Usually, to get low level OS information you can call OS specific commands which give you the information you want with Runtime.exec() or read files such as /proc/* in Linux.

@Neil's answer is one (perfectly valid!) way of doing it, but you can also simply call matplotlib.use('Agg') before importing matplotlib.pyplot, and then continue as normal.

E.g.

import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
fig.savefig('temp.png')

You don't have to use the Agg backend, as well. The pdf, ps, svg, agg, cairo, and gdk backends can all be used without an X-server. However, only the Agg backend will be built by default (I think?), so there's a good chance that the other backends may not be enabled on your particular install.

Alternately, you can just set the backend parameter in your .matplotlibrc file to automatically have matplotlib.pyplot use the given renderer.

The FolderBrowserDialog class from System.Windows.Forms is the recommended way to display a dialog that allows a user to select a folder.

Until recently, the appearance and behaviour of this dialog was not in keeping with the other filesystem dialogs, which is one of the reasons why people were reluctant to use it.

The good news is that FolderBrowserDialog was "modernized" in NET Core 3.0, so is now a viable option for those writing either Windows Forms or WPF apps targeting that version or later.

In .NET Core 3.0, Windows Forms users [sic] a newer COM-based control that was introduced in Windows Vista:

To reference System.Windows.Forms in a NET Core WPF app, it is necessary to edit the project file and add the following line:

<UseWindowsForms>true</UseWindowsForms>

This can be placed directly after the existing <UseWPF> element.

Then it's just a case of using the dialog:

using System;
using System.Windows.Forms;

...

using var dialog = new FolderBrowserDialog
{
    Description = "Time to select a folder",
    UseDescriptionForTitle = true,
    SelectedPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory)
        + Path.DirectorySeparatorChar,
    ShowNewFolderButton = true
};

if (dialog.ShowDialog() == DialogResult.OK)
{
    ...
}

FolderBrowserDialog has a RootFolder property that supposedly "sets the root folder where the browsing starts from" but whatever I set this to it didn't make any difference; SelectedPath seemed to be the better property to use for this purpose, however the trailing backslash is required.

Also, the ShowNewFolderButton property seems to be ignored as well, the button is always shown regardless.

I think the answer in the link below is better

You misspelled permission

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

$scope.arr = [0, 1, 2];  
$scope.dict = {}
for ( var i=0; i < $scope.arr.length; i++ ) {

        $scope.exists = 'yes, 1 exists';
        break;
    }
 }
 if ( $scope.exists ) {
     angular.forEach ( $scope.arr, function ( value, index ) {

$dd = document.getElementById("yourselectelementid");
$so = $dd.options[$dd.selectedIndex];

I used a trial version of ZOC Terminal Emulator and it worked. It readily accepts the Amazon's *.pem files.

The trick is though, that you need to specify "ec2-user" instead of "root" for the username - despite the example shown in the EC2 console, which is wrong! ;-)

Here's yet another answer, from another duplicate question:

SELECT CAST(CAST(getutcdate() - 0.50000004 AS int) AS datetime) 

This magic number method performs slightly faster than the DATEADD method. (It looks like ~10%)

The CPU Time on several rounds of a million records:

DATEADD   MAGIC FLOAT
500       453
453       360
375       375
406       360

But note that these numbers are possibly irrelevant because they are already VERY fast. Unless I had record sets of 100,000 or more, I couldn't even get the CPU Time to read above zero.

Considering the fact that DateAdd is meant for this purpose and is more robust, I'd say use DateAdd.

Use the constructor for appending material to the file:

FileOutputStream(File file, boolean append)
Creates a file output stream to write to the file represented by the specified File object.

So to append to a file say "abc.txt" use

FileOutputStream fos=new FileOutputStream(new File("abc.txt"),true);

The problem is that you're calling List<T>.Reverse() which returns void.

You could either do:

List<string> names = "Tom,Scott,Bob".Split(',').ToList<string>();
names.Reverse();

or:

IList<string> names = "Tom,Scott,Bob".Split(',').Reverse().ToList<string>();

The latter is more expensive, as reversing an arbitrary IEnumerable<T> involves buffering all of the data and then yielding it all - whereas List<T> can do all the reversing "in-place". (The difference here is that it's calling the Enumerable.Reverse<T>() extension method, instead of the List<T>.Reverse() instance method.)

More efficient yet, you could use:

string[] namesArray = "Tom,Scott,Bob".Split(',');
List<string> namesList = new List<string>(namesArray.Length);
namesList.AddRange(namesArray);
namesList.Reverse();

This avoids creating any buffers of an inappropriate size - at the cost of taking four statements where one will do... As ever, weigh up readability against performance in the real use case.

You may have to go from DateTime to LocalDate.

Using Joda Time:

DateTimeFormatter FORMATTER = DateTimeFormat.forPattern("yyyy-MMM-dd");
DateTime dateTime = FORMATTER.parseDateTime("2005-nov-12");
LocalDate localDate = dateTime.toLocalDate();

You can create your own conversion function:

    static long ToLong(string lNumber)
    {
        if (string.IsNullOrEmpty(lNumber))
            throw new Exception("Not a number!");
        char[] chars = lNumber.ToCharArray();
        long result = 0;
        bool isNegative = lNumber[0] == '-';
        if (isNegative && lNumber.Length == 1)
            throw new Exception("- Is not a number!");

        for (int i = (isNegative ? 1:0); i < lNumber.Length; i++)
        {
            if (!Char.IsDigit(chars[i]))
            {
                if (chars[i] == '.' && i < lNumber.Length - 1 && Char.IsDigit(chars[i+1]))
                {
                    var firstDigit = chars[i + 1] - 48;
                    return (isNegative ? -1L:1L) * (result + ((firstDigit < 5) ? 0L : 1L));    
                }
                throw new InvalidCastException($" {lNumber} is not a valid number!");
            }
            result = result * 10 + ((long)chars[i] - 48L);
        }
        return (isNegative ? -1L:1L) * result;
    }

It can be improved further:

• performance wise
• make the validation stricter in the sense that it currently doesn't care if characters after first decimal aren't digits
• specify rounding behavior as parameter for conversion function. it currently does rounding

Please note that Arrays.stream(arr) create a LongStream (or IntStream, ...) instead of Stream so the map function cannot be used to modify the type. This is why .mapToLong, mapToObject, ... functions are provided.

Why not use this logic instead?

public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
    int totalItemCount, lastVisibleItemPosition;

    if (dy > 0) {
      totalItemCount = _layoutManager.getItemCount();
      lastVisibleItemPosition = _layoutManager.findLastVisibleItemPosition();

      if (!_isLastItem) {
        if ((totalItemCount - 1) == lastVisibleItemPosition) {
          LogUtil.e("end_of_list");

          _isLastItem = true;
        }
      }
    }
  }

I was having some issues using the above solutions with an "associative array" type object. These solutions seem to preserve the values, but they do not preserve the actual names of the objects that those values are associated with, which can cause some issues. So I put together the following functions which I am using instead:

function flattenAssocArr(object) {
  if(typeof object == "object") {
    var keys = [];
    keys[0] = "ASSOCARR";
    keys.push(...Object.keys(object));
    var outArr = [];
    outArr[0] = keys;
    for(var i = 1; i < keys.length; i++) {
        outArr[i] = flattenAssocArr(object[keys[i]])
    }
    return outArr;
  } else {
    return object;
  }
}

function expandAssocArr(object) {
    if(typeof object !== "object")
        return object;
    var keys = object[0];
    var newObj = new Object();
    if(keys[0] === "ASSOCARR") {
        for(var i = 1; i < keys.length; i++) {
            newObj[keys[i]] = expandAssocArr(object[i])
        }
    }
    return newObj;
}

Note that these can't be used with any arbitrary object -- basically it creates a new array, stores the keys as element 0, with the data following it. So if you try to load an array that isn't created with these functions having element 0 as a key list, the results might be...interesting :)

I'm using it like this:

var objAsString = JSON.stringify(flattenAssocArr(globalDataset));
var strAsObject = expandAssocArr(JSON.parse(objAsString));

This basically does the same as Mvins answer, but is a more compressed down and simplified version. It works by going back the distance of the radius of the lines adjacent to the corner and connecting both ends with a bezier curve whose control point is at the original corner point.

function createRoundedPath(coords, radius, close) {
  let path = ""
  const length = coords.length + (close ? 1 : -1)
  for (let i = 0; i < length; i++) {
    const a = coords[i % coords.length]
    const b = coords[(i + 1) % coords.length]
    const t = Math.min(radius / Math.hypot(b.x - a.x, b.y - a.y), 0.5)

    if (i > 0) path += `Q${a.x},${a.y} ${a.x * (1 - t) + b.x * t},${a.y * (1 - t) + b.y * t}`

    if (!close && i == 0) path += `M${a.x},${a.y}`
    else if (i == 0) path += `M${a.x * (1 - t) + b.x * t},${a.y * (1 - t) + b.y * t}`

    if (!close && i == length - 1) path += `L${b.x},${b.y}`
    else if (i < length - 1) path += `L${a.x * t + b.x * (1 - t)},${a.y * t + b.y * (1 - t)}`
  }
  if (close) path += "Z"
  return path
}

Getters and Setters in JavaScript

Overview

Getters and setters in JavaScript are used for defining computed properties, or accessors. A computed property is one that uses a function to get or set an object value. The basic theory is doing something like this:

var user = { /* ... object with getters and setters ... */ };
user.phone = '+1 (123) 456-7890'; // updates a database
console.log( user.areaCode ); // displays '123'
console.log( user.area ); // displays 'Anytown, USA'

This is useful for automatically doing things behind-the-scenes when a property is accessed, like keeping numbers in range, reformatting strings, triggering value-has-changed events, updating relational data, providing access to private properties, and more.

The examples below show the basic syntax, though they simply get and set the internal object value without doing anything special. In real-world cases you would modify the input and/or output value to suit your needs, as noted above.

get/set Keywords

ECMAScript 5 supports get and set keywords for defining computed properties. They work with all modern browsers except IE 8 and below.

var foo = {
    bar : 123,
    get bar(){ return bar; },
    set bar( value ){ this.bar = value; }
};
foo.bar = 456;
var gaz = foo.bar;

Custom Getters and Setters

get and set aren't reserved words, so they can be overloaded to create your own custom, cross-browser computed property functions. This will work in any browser.

var foo = {
    _bar : 123,
    get : function( name ){ return this[ '_' + name ]; },
    set : function( name, value ){ this[ '_' + name ] = value; }
};
foo.set( 'bar', 456 );
var gaz = foo.get( 'bar' );

Or for a more compact approach, a single function may be used.

var foo = {
    _bar : 123,
    value : function( name /*, value */ ){
        if( arguments.length < 2 ){ return this[ '_' + name ]; }
        this[ '_' + name ] = value;
    }
};
foo.value( 'bar', 456 );
var gaz = foo.value( 'bar' );

Avoid doing something like this, which can lead to code bloat.

var foo = {
    _a : 123, _b : 456, _c : 789,
    getA : function(){ return this._a; },
    getB : ..., getC : ..., setA : ..., setB : ..., setC : ...
};

For the above examples, the internal property names are abstracted with an underscore in order to discourage users from simply doing foo.bar vs. foo.get( 'bar' ) and getting an "uncooked" value. You can use conditional code to do different things depending on the name of the property being accessed (via the name parameter).

Object.defineProperty()

Using Object.defineProperty() is another way to add getters and setters, and can be used on objects after they're defined. It can also be used to set configurable and enumerable behaviors. This syntax also works with IE 8, but unfortunately only on DOM objects.

var foo = { _bar : 123 };
Object.defineProperty( foo, 'bar', {
    get : function(){ return this._bar; },
    set : function( value ){ this._bar = value; }
} );
foo.bar = 456;
var gaz = foo.bar;

__defineGetter__()

Finally, __defineGetter__() is another option. It's deprecated, but still widely used around the web and thus unlikely to disappear anytime soon. It works on all browsers except IE 10 and below. Though the other options also work well on non-IE, so this one isn't that useful.

var foo = { _bar : 123; }
foo.__defineGetter__( 'bar', function(){ return this._bar; } );
foo.__defineSetter__( 'bar', function( value ){ this._bar = value; } );

Also worth noting is that in the latter examples, the internal names must be different than the accessor names to avoid recursion (ie, foo.bar calling foo.get(bar) calling foo.bar calling foo.get(bar)...).

<- does assignment in the current environment.

When you're inside a function R creates a new environment for you. By default it includes everything from the environment in which it was created so you can use those variables as well but anything new you create will not get written to the global environment.

In most cases <<- will assign to variables already in the global environment or create a variable in the global environment even if you're inside a function. However, it isn't quite as straightforward as that. What it does is checks the parent environment for a variable with the name of interest. If it doesn't find it in your parent environment it goes to the parent of the parent environment (at the time the function was created) and looks there. It continues upward to the global environment and if it isn't found in the global environment it will assign the variable in the global environment.

This might illustrate what is going on.

bar <- "global"
foo <- function(){
    bar <- "in foo"
    baz <- function(){
        bar <- "in baz - before <<-"
        bar <<- "in baz - after <<-"
        print(bar)
    }
    print(bar)
    baz()
    print(bar)
}
> bar
[1] "global"
> foo()
[1] "in foo"
[1] "in baz - before <<-"
[1] "in baz - after <<-"
> bar
[1] "global"

The first time we print bar we haven't called foo yet so it should still be global - this makes sense. The second time we print it's inside of foo before calling baz so the value "in foo" makes sense. The following is where we see what <<- is actually doing. The next value printed is "in baz - before <<-" even though the print statement comes after the <<-. This is because <<- doesn't look in the current environment (unless you're in the global environment in which case <<- acts like <-). So inside of baz the value of bar stays as "in baz - before <<-". Once we call baz the copy of bar inside of foo gets changed to "in baz" but as we can see the global bar is unchanged. This is because the copy of bar that is defined inside of foo is in the parent environment when we created baz so this is the first copy of bar that <<- sees and thus the copy it assigns to. So <<- isn't just directly assigning to the global environment.

<<- is tricky and I wouldn't recommend using it if you can avoid it. If you really want to assign to the global environment you can use the assign function and tell it explicitly that you want to assign globally.

Now I change the <<- to an assign statement and we can see what effect that has:

bar <- "global"
foo <- function(){
    bar <- "in foo"   
    baz <- function(){
        assign("bar", "in baz", envir = .GlobalEnv)
    }
    print(bar)
    baz()
    print(bar)
}
bar
#[1] "global"
foo()
#[1] "in foo"
#[1] "in foo"
bar
#[1] "in baz"

So both times we print bar inside of foo the value is "in foo" even after calling baz. This is because assign never even considered the copy of bar inside of foo because we told it exactly where to look. However, this time the value of bar in the global environment was changed because we explicitly assigned there.

Now you also asked about creating local variables and you can do that fairly easily as well without creating a function... We just need to use the local function.

bar <- "global"
# local will create a new environment for us to play in
local({
    bar <- "local"
    print(bar)
})
#[1] "local"
bar
#[1] "global"

ps aux | grep java

or

$ ps -fea|grep -i java

Styling the infowindow is fairly straightforward with vanilla javascript. I used some of the info from this thread when writing this. I also took into account the possible problems with earlier versions of ie (although I have not tested it with them).

var infowindow = new google.maps.InfoWindow({
  content: '<div id="gm_content">'+contentString+'</div>'
});

google.maps.event.addListener(infowindow,'domready',function(){
  var el = document.getElementById('gm_content').parentNode.parentNode.parentNode;
  el.firstChild.setAttribute('class','closeInfoWindow');
  el.firstChild.setAttribute('title','Close Info Window');
  el = (el.previousElementSibling)?el.previousElementSibling:el.previousSibling;
  el.setAttribute('class','infoWindowContainer');
  for(var i=0; i<11; i++){
    el = (el.previousElementSibling)?el.previousElementSibling:el.previousSibling;
    el.style.display = 'none';
  }
});

The code creates the infowindow as usual (no need for plugins, custom overlays or huge code), using a div with an id to hold the content. This gives a hook in the system that we can use to get the correct elements to manipulate with a simple external stylesheet.

There are a couple of extra pieces (that are not strictly needed) which handle things like giving a hook into the div with the close info window image in it.

The final loop hides all the pieces of the pointer arrow. I needed this myself as I wanted to have transparency on the infowindow and the arrow got in the way. Of course, with the hook, changing the code to replace the arrow image with a png of your choice should be fairly simple too.

If you want to change it to jquery (no idea why you would) then that should be fairly simple.

I'm not usually a javascript developer so any thoughts, comments, criticisms welcome :)

The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data.

Alternatively when you submit POST form to non-existing URL, web container will display 405 error (method not allowed) instead of 404 (not found).

To fix:

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

Something like the following would get you closer

class Clazz
{
   public static <U extends Clazz> void doIt(U thing)
   {
   }
}

EDIT: Updated example with more detail

public abstract class Thingo 
{

    public static <U extends Thingo> void doIt(U p_thingo)
    {
        p_thingo.thing();
    }

    protected abstract void thing();

}

class SubThingoOne extends Thingo
{
    @Override
    protected void thing() 
    {
        System.out.println("SubThingoOne");
    }
}

class SubThingoTwo extends Thingo
{

    @Override
    protected void thing() 
    {
        System.out.println("SuThingoTwo");
    }

}

public class ThingoTest 
{

    @Test
    public void test() 
    {
        Thingo t1 = new SubThingoOne();
        Thingo t2 = new SubThingoTwo();

        Thingo.doIt(t1);
        Thingo.doIt(t2);

        // compile error -->  Thingo.doIt(new Object());
    }
}

You can wrap them in a div and give the div a set width (the width of the widest image + margin maybe?) and then float the divs. Then, set the images to the center of their containing divs. Your margins between images won't be consistent for the differently sized images but it'll lay out much more nicely on the page.

I tried invalidating caches and restarting, but the only thing that worked for me was wiping out the .idea directory completely, then creating a new project from scratch.

I had a bunch of FKs to alter, so I wrote something to make the statements for me. Figured I'd share:

SELECT

CONCAT('ALTER TABLE `' ,rc.TABLE_NAME,
    '` DROP FOREIGN KEY `' ,rc.CONSTRAINT_NAME,'`;')
, CONCAT('ALTER TABLE `' ,rc.TABLE_NAME,
    '` ADD CONSTRAINT `' ,rc.CONSTRAINT_NAME ,'` FOREIGN KEY (`',kcu.COLUMN_NAME,
    '`) REFERENCES `',kcu.REFERENCED_TABLE_NAME,'` (`',kcu.REFERENCED_COLUMN_NAME,'`) ON DELETE CASCADE;')

FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc
LEFT OUTER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE kcu
    ON kcu.TABLE_SCHEMA = rc.CONSTRAINT_SCHEMA
    AND kcu.CONSTRAINT_NAME = rc.CONSTRAINT_NAME
WHERE DELETE_RULE = 'NO ACTION'
AND rc.CONSTRAINT_SCHEMA = 'foo'

You can use below code :

var vc = self.storyboard?.instantiateViewControllerWithIdentifier("YourViewController") as! YourViewController;
            vc.mode_Player = 1
            self.presentViewController(vc, animated: true, completion: nil)

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

Yes, you can use json_encode to take your HTML string and escape it as necessary.

Note that in JSON, the top level item must be an array or object (that's not true anymore), it cannot just be a string. So you'll want to create an object and make the HTML string a property of the object (probably the only one), so the resulting JSON looks something like:

{"html": "<p>I'm the markup</p>"}

<c:if test="${companies.size() > 0}">

</c:if>

This syntax works only in EL 2.2 or newer (Servlet 3.0 / JSP 2.2 or newer). If you're facing a XML parsing error because you're using JSPX or Facelets instead of JSP, then use gt instead of >.

<c:if test="${companies.size() gt 0}">

</c:if>

If you're actually facing an EL parsing error, then you're probably using a too old EL version. You'll need JSTL fn:length() function then. From the documentation:

length( java.lang.Object) - Returns the number of items in a collection, or the number of characters in a string.

Put this at the top of JSP page to allow the fn namespace:

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

Or if you're using JSPX or Facelets:

<... xmlns:fn="http://java.sun.com/jsp/jstl/functions">

And use like this in your page:

<p>The length of the companies collection is: ${fn:length(companies)}</p>

So to test with length of a collection:

<c:if test="${fn:length(companies) gt 0}">

</c:if>

Alternatively, for this specific case you can also simply use the EL empty operator:

<c:if test="${not empty companies}">

</c:if>

Get a backup copy of the .metadata/.plugin/org.eclipse.core.resources folder, then delete that folder and launch eclipse. That should launch the workspace, but all projects will be gone as org.eclipse.core.resources keeps a list of all projects.

Next, close eclipse properly and copy back org.eclipse.core.resources from back up to .metadata/.plugins/ folder overriding the existing one.

Open eclipse and things should work fine with all your projects back to normal.

You really should try to google first.

Wikipedia has a explanation of leap years. The algorithm your describing is for the Proleptic Gregorian calendar.

More about the math around it can be found in the article Calendar Algorithms.

You can still use the Screen class from a WPF app. You just need to reference the System.Windows.Forms assembly from your application. Once you've done that, (and referenced System.Drawing for the example below):

Rectangle workingArea = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;

...works just fine.

Have you considered setting your main window property WindowStartupLocation to CenterScreen?

This theme required awhile to find results and reasons:

using MaiaDB 5.4. via SuSE-LINUX tumblweed

1. some files in the appointed directory havn't been necessary in any direct relation with mariadb. I.e: I placed some hints, a text-file, some bakup-copys somewhere in the same appointed directory for mysql mariadb and this caused endless error-messages and blocking the server from starting. Mariadb appears to be very sensible and hostile with the presence of other files not beeing database files(comments,backups,experimantal files etc) .

2. using libreoffice as client then there already this generated much problems with the creation and working on a database and caused some crashes.The crashes eventually produced bad tables.

3. May be because of that or may be because of the presence of not yet deleted but unusable tables !! the mysql mariadb server crashed and didn't want to do it' job not even start.

Error message always same : "Table 'some.table' doesn't exist in engine"

But when it started then tables appeared as normal, but it was unpossible to work on them.

So what to do without a more precise Error Message ?? The unusable tables showed up with: "CHECK TABLE" or on the command line of the system with "mysqlcheck " So I deleted by filemanager or on the system-level as root or as allowed user all the questionable files and then problem was solved.

Proposal: the Error Message could be a bit more precisely for example: "corrupted tables" (which can be found by CHECK TABLE, but only if the server is running) or by mysqlcheck even whe server is not running - but here are other disturbing files like hints/bakups a.s.o not visible.

ANYWAY it helped a lot to have backup-copies of the original database-files on a backup volume. This helped to check out and test it again and again until solution was found.

Good luck all - Herbert

If you want millisecond precision, try this:

CREATE TABLE my_table (
    timestamp DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))
);

This will save the timestamp as text, though.

In every distribute it has difference files so I write most common ones:

---- CentOS Linux distro
`cat /proc/version`
---- Debian Linux distro
`cat /etc/debian_version`
---- Redhat Linux distro
`cat /etc/redhat-release` 
---- Ubuntu Linux distro
`cat /etc/issue`   or   `cat /etc/lsb-release`

in last one /etc/issue didn't exist so I tried the second one and it returned the right answer

If you're using it in several different places, you should turn it into a plugin.

jQuery.fn.fadeOutAndRemove = function(speed){
    $(this).fadeOut(speed,function(){
        $(this).remove();
    })
}

And then:

// Somewhere in the program code.
$('div').fadeOutAndRemove('fast');

Hi This can be solved by changing the prorperty of the project in the solution explorer then give false to 64bit runtime option

I tried the code provided by Ranadheer Reddy (above) and it worked great. If you’re using a company computer that has a restricted server you may need to change the SMTP port to 25 and leave your username and password blank since they will auto fill by your admin.

Originally, I tried using EASendMail from the nugent package manager, only to realize that it’s a pay for version with 30-day trial. Don’t waist your time with it unless you plan on buying it. I noticed the program ran much faster using EASendMail, but for me, free trumped fast.

Just my 2 cents worth.

Create Function

function toggleFullScreen() {

            if ((document.fullScreenElement && document.fullScreenElement !== null) ||
                    (!document.mozFullScreen && !document.webkitIsFullScreen)) {
             $scope.topMenuData.showSmall = true;
                if (document.documentElement.requestFullScreen) {
                    document.documentElement.requestFullScreen();
                } else if (document.documentElement.mozRequestFullScreen) {
                    document.documentElement.mozRequestFullScreen();
                } else if (document.documentElement.webkitRequestFullScreen) {
                    document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
                }
            } else {

                  $scope.topMenuData.showSmall = false;
                if (document.cancelFullScreen) {
                    document.cancelFullScreen();
                } else if (document.mozCancelFullScreen) {
                    document.mozCancelFullScreen();
                } else if (document.webkitCancelFullScreen) {
                    document.webkitCancelFullScreen();
                }
            }
        }

In Html Put Code like

<ul class="unstyled-list fg-white">

            <li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
            <li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
        </ul>

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

$ man memset

MEMSET(3)                BSD Library Functions Manual                MEMSET(3)

NAME
     memset -- fill a byte string with a byte value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memset(void *b, int c, size_t len);

Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>/<cstdio>/<cstdlib>/etc, rather than C's <string.h>/<stdio.h>/<stdlib.h>/etc.

I'm pretty sure there'll be some C# SDKs / toolkits on Google Code for this. I found this one, but there may be others so it's worth having a browse around.

The nuget.exe utility doesn't have this feature, but seeing that the NuGet cache is simply a folder on your computer, you can delete the files manually. Just add this to your batch file:

del %LOCALAPPDATA%\NuGet\Cache\*.nupkg /q

String dir = getFilesDir().getAbsolutePath();
File f0 = new File(dir, "myFile");
boolean d0 = f0.delete(); 
Log.w("Delete Check", "File deleted: " + dir + "/myFile " + d0);

The code File dir = getFilesDir(); doesn't work because this is a request for a File object. You're trying to retrieve the String that declares the path to your directory, so you need to declare 'dir' as a String, and then request that the directory's absolute path in String form be returned by the constructor that has access to that information.

I don't think so. Just use two IFs and GOTO the same label:

IF cond1 GOTO foundit
IF cond2 GOTO foundit

ECHO Didn't found it
GOTO end

:foundit
ECHO Found it!

:end

You can also use a jQuery plugin to do that

@warsong is right. Installing only lib32stdc++6 solved the problem.

For next uses I rewrite @warsongs comment in answer area.

sudo apt-get install lib32stdc++6

One of the possible solution you might be interested in. Traversing an array of chars from right to left and vise versa in one loop.

public static string WordsToCapitalLetter(string value)
    {
        if (string.IsNullOrWhiteSpace(value))
        {
            throw new ArgumentException("value");
        }

        int inputValueCharLength = value.Length;
        var valueAsCharArray = value.ToCharArray();

        int min = 0;
        int max = inputValueCharLength - 1;

        while (max > min)
        {
            char left = value[min];
            char previousLeft = (min == 0) ? left : value[min - 1];

            char right = value[max];
            char nextRight = (max == inputValueCharLength - 1) ? right : value[max - 1];

            if (char.IsLetter(left) && !char.IsUpper(left) && char.IsWhiteSpace(previousLeft))
            {
                valueAsCharArray[min] = char.ToUpper(left);
            }

            if (char.IsLetter(right) && !char.IsUpper(right) && char.IsWhiteSpace(nextRight))
            {
                valueAsCharArray[max] = char.ToUpper(right);
            }

            min++;
            max--;
        }

        return new string(valueAsCharArray);
    }

System.Diagnostics.Stopwatch is designed for this task.

Add the all tiles jars like(tiles-jsp,tiles-servlet,tiles-template,tiles-extras.tiles-core ) to your server lib folder and your application build path then it work if you using apache tailes with spring mvc application
