Programming the Mandelbrot is easy.
My quick-n-dirty code is below (not guaranteed to be bug-free, but a good outline).

Here's the outline: The Mandelbrot-set lies in the Complex-grid completely within a circle with radius 2.

So, start by scanning every point in that rectangular area. Each point represents a Complex number (x + yi). Iterate that complex number:

[new value] = [old-value]^2 + [original-value] while keeping track of two things:

1.) the number of iterations

2.) the distance of [new-value] from the origin.

If you reach the Maximum number of iterations, you're done. If the distance from the origin is greater than 2, you're done.

When done, color the original pixel depending on the number of iterations you've done. Then move on to the next pixel.

public void MBrot()
{
    float epsilon = 0.0001; // The step size across the X and Y axis
    float x;
    float y;
    int maxIterations = 10; // increasing this will give you a more detailed fractal
    int maxColors = 256; // Change as appropriate for your display.

    Complex Z;
    Complex C;
    int iterations;
    for(x=-2; x<=2; x+= epsilon)
    {
        for(y=-2; y<=2; y+= epsilon)
        {
            iterations = 0;
            C = new Complex(x, y);
            Z = new Complex(0,0);
            while(Complex.Abs(Z) < 2 && iterations < maxIterations)
            {
                Z = Z*Z + C;
                iterations++;
            }
            Screen.Plot(x,y, iterations % maxColors); //depending on the number of iterations, color a pixel.
        }
    }
}

Some details left out are:

1.) Learn exactly what the Square of a Complex number is and how to calculate it.

2.) Figure out how to translate the (-2,2) rectangular region to screen coordinates.

Seems like the problem is with the date format.

 var d = "17-09-2013 10:08",
 dArr = d.split('-'),
 ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

I agree that it isn't sufficient to Select *, if that one you don't need, as mentioned elsewhere, is a BLOB, you don't want to have that overhead creep in.

I would create a view with the required data, then you can Select * in comfort --if the database software supports them. Else, put the huge data in another table.

Maybe another quick solution could be:

>>> float("%.1f" % 1.00001)
1.0
>>> float("%.3f" % 1.23001)
1.23
>>> float("%.5f" % 1.23001)
1.23001

phpMyAdmin provides a GUI for this within the structure view of a table. Check to select the column you want to move and click the change action at the bottom of the column list. You can then change all of the column properties and you'll find the 'move column' function at the far right of the screen.

Of course this is all just building the queries in the perfectly good top answer but GUI fans might appreciate the alternative.

my phpMyAdmin version is 4.1.7

If you are passing data to a DOM element from the server, you should set the data on the element:

<a id="foo" data-foo="bar" href="#">foo!</a>

The data can then be accessed using .data() in jQuery:

console.log( $('#foo').data('foo') );
//outputs "bar"

However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.

$('#foo').data('foo', 'baz');

console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed

console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object

Also, the naming convention for data attributes has a bit of a hidden "gotcha":

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd

The hyphenated key will still work:

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"

However the object returned by .data() will not have the hyphenated key set:

$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work

It's for this reason I suggest avoiding the hyphenated key in javascript.

For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>, <DIV DATA-FOOBAR></DIV>, and <dIv DaTa-FoObAr></DiV> are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.

The .data() method will also perform some basic auto-casting if the value matches a recognized pattern:

<a id="foo"
    href="#"
    data-str="bar"
    data-bool="true"
    data-num="15"
    data-json='{"fizz":["buzz"]}'>foo!</a>

$('#foo').data('str');  //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num');  //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`

This auto-casting ability is very convenient for instantiating widgets & plugins:

$('.widget').each(function () {
    $(this).widget($(this).data());
    //-or-
    $(this).widget($(this).data('widget'));
});

If you absolutely must have the original value as a string, then you'll need to use .attr():

<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>

$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers

$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6

_{This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number as of jQuery 1.8 rc 1.}

jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number would be cast to Number. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.

<a id="foo"
    href="#"
    data-int="1000"
    data-decimal="1000.00"
    data-scientific="1e3"
    data-hex="0x03e8">foo!</a>

                              // pre 1.8    post 1.8
$('#foo').data('int');        //    1000        1000
$('#foo').data('decimal');    //    1000   "1000.00"
$('#foo').data('scientific'); //    1000       "1e3"
$('#foo').data('hex');        //    1000     "0x03e8"

If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number first, such as with a unary + operator.

+$('#foo').data('hex'); // 1000

This was sort of tricky for me too, I did the following which worked pretty well.

• Download the appropriate Python .egg for setuptools (ie, for Python 2.6, you can get it here. Grab the correct one from the PyPI site here.)
• chmod the egg to be executable: chmod a+x [egg] (ie, for Python 2.6, chmod a+x setuptools-0.6c9-py2.6.egg)
• Run ./[egg] (ie, for Python 2.6, ./setuptools-0.6c9-py2.6.egg)

Not sure if you'll need to use sudo if you're just installing it for you current user. You'd definitely need it to install it for all users.

The join is called on the string:

print ", ".join(set_3)

One more approach, what you can do is

// get your optionals first
Optional<String> p1 = otherObject.getP1();
Optional<BigInteger> p2 = otherObject.getP2();

// bind values to a function
Supplier<Integer> calculatedValueSupplier = () -> { // your logic here using both optional as state}

Once you have built a function(supplier in this case) you will be able to pass this around as any other variable and would be able to call it using

calculatedValueSupplier.apply();

The idea here being whether you have got optional value or not will be internal detail of your function and will not be in parameter. Thinking functions when thinking about optional as parameter is actually very useful technique that I have found.

As to your question whether you should actually do it or not is based on your preference, but as others said it makes your API ugly to say the least.

There is now a beta available of Google Maps KML Importing Utility.

It is part of the Google Maps Android API Utility Library. As documented it allows loading KML files from streams

KmlLayer layer = new KmlLayer(getMap(), kmlInputStream, getApplicationContext());

or local resources

KmlLayer layer = new KmlLayer(getMap(), R.raw.kmlFile, getApplicationContext());

After you have created a KmlLayer, call addLayerToMap() to add the imported data onto the map.

layer.addLayerToMap();

int? here = (list.ElementAtOrDefault(2) != 0 ? list[2]:(int?) null);

For me this worked in a vagrant VM:

sudo /usr/bin/passwd root <<EOF
12345678
12345678
EOF

When generating CSR is possible to specify -ext attribute again to have it inserted in the CSR

keytool -certreq -file test.csr -keystore test.jks -alias testAlias -ext SAN=dns:test.example.com

        m.invoke(null, new Object[] {args});
        break;
    }
}

    }
    static void Main(string[] args)
    {
        Program ob = new Program();
        ob.LeftJoin();
        Console.ReadLine();
    }

    private void LeftJoin()
    {
        listOfEmp.GroupJoin(listOfDepart.DefaultIfEmpty(), x => x.DepartmentId, y => y.Id, (x, y) => new { EmpId = x.Empid, EmpName = x.Name, Dpt = y.FirstOrDefault() != null ? y.FirstOrDefault().DeptName : null }).ToList().ForEach
            (z =>
            {
                Console.WriteLine("Empid:{0} EmpName:{1} Dept:{2}", z.EmpId, z.EmpName, z.Dpt);
            });
    }
}

class Employee
{
    public int Empid { get; set; }
    public string Name { get; set; }
    public int DepartmentId { get; set; }
}

class Department
{
    public int Id { get; set; }
    public string DeptName { get; set; }
}

Another way to make it in Python 3:

Just in case someone is using Bootstrap, I was able to add more than one class:

<a href="" class="baseclass" th:classappend="${isAdmin} ?: 'text-danger font-italic' "></a>

If you look at the hive-site.xml file you will see something like this

<property>
   <name>hive.metastore.warehouse.dir</name>
   <value>/usr/hive/warehouse </value>
   <description>location of the warehouse directory</description>
 </property>

/usr/hive/warehouse is the default location for all managed tables. External tables may be stored at a different location.

describe formatted <table_name> is the hive shell command which can be use more generally to find the location of data pertaining to a hive table.

In Github You need to write:

<p align="justify">
  Lorem ipsum

I faced the same issue when I tried to publish Debug version of my web application. This set of files didn't contain the file web.config with the proper value of attribute processPath.

I took this file from Release version, value was assigned to the path to my exe file.

<aspNetCore processPath=".\My.Web.App.exe" ... />

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read() 

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

Factory

You give AngularJS a function, AngularJS will cache and inject the return value when the factory is requested.

Example:

app.factory('factory', function() {
    var name = '';
    // Return value **is** the object that will be injected
    return {
        name: name;
    }
})

Usage:

app.controller('ctrl', function($scope, factory) {
     $scope.name = factory.name;
});

Service

You give AngularJS a function, AngularJS will call new to instantiate it. It is the instance that AngularJS creates that will be cached and injected when the service is requested. Since new was used to instantiate the service, the keyword this is valid and refers to the instance.

Example:

app.service('service', function() {
     var name = '';
     this.setName = function(newName) {
         name = newName;
     }
     this.getName = function() {
         return name;
     }
});

Usage:

app.controller('ctrl', function($scope, service) {
   $scope.name = service.getName();
});

Provider

You give AngularJS a function, and AngularJS will call its $get function. It is the return value from the $get function that will be cached and injected when the service is requested.

Providers allow you to configure the provider before AngularJS calls the $get method to get the injectible.

Example:

app.provider('provider', function() {
     var name = '';
     this.setName = function(newName) {
          name = newName;
     }
     this.$get = function() {
         return {
            name: name
         }
     }
})

Usage (as an injectable in a controller)

app.controller('ctrl', function($scope, provider) {
    $scope.name = provider.name;
});

Usage (configuring the provider before $get is called to create the injectable)

app.config(function(providerProvider) {
    providerProvider.setName('John');
});

I was surprised that nobody mentioned this:

RedirectMatch ^/$ /store/

Basically, it redirects the root and only the root URL. The answer originated from this link

In my case, I had to create local.properties file with sdk.dir=PATH_TO_ANDROID_SDK in my machine. It seems that, it's regarding the android sdk path setup. Hence, it could also be set in ANDROID_HOME env. variable too.

URL -- Uniform Resource Locator

Contains information about how to fetch a resource from its location. For example:

• http://example.com/mypage.html
• ftp://example.com/download.zip
• mailto:[email protected]
• file:///home/user/file.txt
• http://example.com/resource?foo=bar#fragment
• /other/link.html (A relative URL, only useful in the context of another URL)

URLs always start with a protocol (http) and usually contain information such as the network host name (example.com) and often a document path (/foo/mypage.html). URLs may have query parameters and fragment identifiers.

URN -- Uniform Resource Name

Identifies a resource by name. It always starts with the prefix urn: For example:

• urn:isbn:0451450523 to identify a book by its ISBN number.
• urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66 a globally unique identifier
• urn:publishing:book - An XML namespace that identifies the document as a type of book.

URNs can identify ideas and concepts. They are not restricted to identifying documents. When a URN does represent a document, it can be translated into a URL by a "resolver". The document can then be downloaded from the URL.

URI -- Uniform Resource Identifier

URIs encompasses both URLs, URNs, and other ways to indicate a resource.

An example of a URI that is neither a URL nor a URN would be a data URI such as data:,Hello%20World. It is not a URL or URN because the URI contains the data. It neither names it, nor tells you how to locate it over the network.

There are also uniform resource citations (URCs) that point to meta data about a document rather than to the document itself. An example of a URC would be an indicator for viewing the source code of a web page: view-source:http://example.com/. A URC is another type of URI that is neither URL nor URN.

Frequently Asked Questions

I've heard that I shouldn't say URL anymore, why?

The w3 spec for HTML says that the href of an anchor tag can contain a URI, not just a URL. You should be able to put in a URN such as <a href="urn:isbn:0451450523">. Your browser would then resolve that URN to a URL and download the book for you.

Do any browsers actually know how to fetch documents by URN?

Not that I know of, but modern web browser do implement the data URI scheme.

Can a URI be both a URL and a URN?

Good question. I've seen lots of places on the web that state this is true. I haven't been able to find any examples of something that is both a URL and a URN. I don't see how it is possible because a URN starts with urn: which is not a valid network protocol.

Does the difference between URL and URI have anything to do with whether it is relative or absolute?

No. Both relative and absolute URLs are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has query parameters?

No. Both URLs with and without query parameters are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has a fragment identifier?

No. Both URLs with and without fragment identifiers are URLs (and URIs.)

Is a tel: URI a URL or a URN?

For example tel:1-800-555-5555. It doesn't start with urn: and it has a protocol for reaching a resource over a network. It must be a URL.

But doesn't the w3C now say that URLs and URIs are the same thing?

Yes. The W3C realized that there is a ton of confusion about this. They issued a URI clarification document that says that it is now OK to use URL and URI interchangeably. It is no longer useful to strictly segment URIs into different types such as URL, URN, and URC.

Use toCharArray() method. It splits the string into an array of characters:

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#toCharArray%28%29

String str = "aabbab";
char[] chs = str.toCharArray();

Just wanted to add to this, you can have the :not selector in oldIE using selectivizr: http://selectivizr.com/

Combining R.. and PickBoy answers for brevity

long strtol (const char *String, char **EndPointer, int Base)

// examples
strtol(s, NULL, 10);
strtol(s, &s, 10);

The answer is: It depends.

Although base64-images are larger, there a few conditions where base64 is the better choice.

Size of base64-images

Base64 uses 64 different characters and this is 2^6. So base64 stores 6bit per 8bit character. So the proportion is 6/8 from unconverted data to base64 data. This is no exact calculation, but a rough estimate.

Example:

An 48kb image needs around 64kb as base64 converted image.

Calculation: (48 / 6) * 8 = 64

Simple CLI calculator on Linux systems:

$ cat /dev/urandom|head -c 48000|base64|wc -c
64843

Or using an image:

$ cat my.png|base64|wc -c

Base64-images and websites

This question is much more difficult to answer. Generally speaking, as larger the image as less sense using base64. But consider the following points:

• A lot of embedded images in an HTML-File or CSS-File can have similar strings. For PNGs you often find repeated "A" chars. Using gzip (sometimes called "deflate"), there might be even a win on size. But it depends on image content.
• Request overhead of HTTP1.1: Especially with a lot of cookies you can easily have a few kilobytes overhead per request. Embedding base64 images might save bandwith.
• Do not base64 encode SVG images, because gzip is more effective on XML than on base64.
• Programming: On dynamically generated images it is easier to deliver them in one request as to coordinate two dependent requests.
• Deeplinks: If you want to prevent downloading the image, it is a little bit trickier to extract an image from an HTML page.

Your problem is that all chapters, whether they're in the appendix or not, default to starting on an odd-numbered page when you're in two-sided layout mode. A few possible solutions:

The simplest solution is to use the openany option to your document class, which makes chapters start on the next page, irrespective of whether it's an odd or even numbered page. This is supported in the standard book documentclass, eg \documentclass[openany]{book}. (memoir also supports using this as a declaration \openany which can be used in the middle of a document to change the behavior for subsequent pages.)

Another option is to try the \let\cleardoublepage\clearpage command before your appendices to avoid the behavior.

Or, if you don't care using a two-sided layout, using the option oneside to your documentclass (eg \documentclass[oneside]{book}) will switch to using a one-sided layout.

You can use database from here -

http://myip.ms/info/cities_sql_database/

CREATE TABLE `cities` (
  `cityID` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
  `cityName` varchar(50) NOT NULL,
  `stateID` smallint(5) unsigned NOT NULL DEFAULT '0',
  `countryID` varchar(3) NOT NULL DEFAULT '',
  `language` varchar(10) NOT NULL DEFAULT '',
  `latitude` double NOT NULL DEFAULT '0',
  `longitude` double NOT NULL DEFAULT '0',
  PRIMARY KEY (`cityID`),
  UNIQUE KEY `unq` (`countryID`,`stateID`,`cityID`),
  KEY `cityName` (`cityName`),
  KEY `stateID` (`stateID`),
  KEY `countryID` (`countryID`),
  KEY `latitude` (`latitude`),
  KEY `longitude` (`longitude`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8;

insert the image and then backhand all you need is:

<style>
img {
  border-radius: 50%;
}
</style>

** the image code will be here automatically**

Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps

First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'

@Bean  
@Primary  
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {  
  return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());  
}  

Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.

public static <T> T build(Message message, Class<T> type) {
  Printer printer = JsonFormat.printer();
  Gson gson = new Gson();
  try {
    return gson.fromJson(printer.print(message), type);
  } catch (JsonSyntaxException | InvalidProtocolBufferException e) {
    throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response   conversion Error", e);
  }
}

Then you can call this method from your controller class as last line like -

return ResponseBuilder.build(<returned_service_object>, <Type>);

Hope this will help you to implement protobuf in json format.

I have been reading about using model concerns to skin-nize fat models as well as DRY up your model codes. Here is an explanation with examples:

1) DRYing up model codes

Consider a Article model, a Event model and a Comment model. An article or an event has many comments. A comment belongs to either Article or Event.

Traditionally, the models may look like this:

Comment Model:

class Comment < ActiveRecord::Base
  belongs_to :commentable, polymorphic: true
end

Article Model:

class Article < ActiveRecord::Base
  has_many :comments, as: :commentable 

  def find_first_comment
    comments.first(created_at DESC)
  end

  def self.least_commented
   #return the article with least number of comments
  end
end

Event Model

class Event < ActiveRecord::Base
  has_many :comments, as: :commentable 

  def find_first_comment
    comments.first(created_at DESC)
  end

  def self.least_commented
   #returns the event with least number of comments
  end
end

As we can notice, there is a significant piece of code common to both Event and Article. Using concerns we can extract this common code in a separate module Commentable.

For this create a commentable.rb file in app/models/concerns.

module Commentable
  extend ActiveSupport::Concern

  included do
    has_many :comments, as: :commentable
  end

  # for the given article/event returns the first comment
  def find_first_comment
    comments.first(created_at DESC)
  end

  module ClassMethods
    def least_commented
      #returns the article/event which has the least number of comments
    end
  end
end

And now your models look like this :

Comment Model:

class Comment < ActiveRecord::Base
  belongs_to :commentable, polymorphic: true
end

Article Model:

class Article < ActiveRecord::Base
  include Commentable
end

Event Model:

class Event < ActiveRecord::Base
  include Commentable
end

2) Skin-nizing Fat Models.

Consider a Event model. A event has many attenders and comments.

Typically, the event model might look like this

class Event < ActiveRecord::Base   
  has_many :comments
  has_many :attenders


  def find_first_comment
    # for the given article/event returns the first comment
  end

  def find_comments_with_word(word)
    # for the given event returns an array of comments which contain the given word
  end 

  def self.least_commented
    # finds the event which has the least number of comments
  end

  def self.most_attended
    # returns the event with most number of attendes
  end

  def has_attendee(attendee_id)
    # returns true if the event has the mentioned attendee
  end

Models with many associations and otherwise have tendency to accumulate more and more code and become unmanageable. Concerns provide a way to skin-nize fat modules making them more modularized and easy to understand.

The above model can be refactored using concerns as below: Create a attendable.rb and commentable.rb file in app/models/concerns/event folder

attendable.rb

module Attendable
  extend ActiveSupport::Concern

  included do 
    has_many :attenders
  end

  def has_attender(attender_id)
    # returns true if the event has the mentioned attendee
  end

  module ClassMethods
    def most_attended
      # returns the event with most number of attendes
    end
  end
end

commentable.rb

module Commentable
  extend ActiveSupport::Concern

  included do 
    has_many :comments
  end

  def find_first_comment
    # for the given article/event returns the first comment
  end

  def find_comments_with_word(word)
    # for the given event returns an array of comments which contain the given word
  end

  module ClassMethods
    def least_commented
      # finds the event which has the least number of comments
    end
  end
end

And now using Concerns, your Event model reduces to

class Event < ActiveRecord::Base
  include Commentable
  include Attendable
end

* While using concerns its advisable to go for 'domain' based grouping rather than 'technical' grouping. Domain Based grouping is like 'Commentable', 'Photoable', 'Attendable'. Technical grouping will mean 'ValidationMethods', 'FinderMethods' etc

Just echo your content after sending the header.

header('HTTP/1.0 403 Forbidden');

echo 'You are forbidden!';

Improving Suman.hassan95's answer by adding a link to subcategory as well. Replace the following code:

$sub_cats = get_categories( $args2 );
    if($sub_cats) {
        foreach($sub_cats as $sub_category) {
            echo  $sub_category->name ;
        }

    }

with:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                }
            }

or if you also wish a counter for each subcategory, replace with this:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                    echo apply_filters( 'woocommerce_subcategory_count_html', ' <span class="cat-count">' . $sub_category->count . '</span>', $category );
                }
            }

if not orgs:
    # Do this...
else:
    # Do that...

You can show changes that have been staged with the --cached flag:

$ git diff --cached

In more recent versions of git, you can also use the --staged flag (--staged is a synonym for --cached):

$ git diff --staged

Remove everything after first digit (was adequate for my use case): LEFT(field,PATINDEX('%[0-9]%',field+'0')-1)

Remove trailing digits: LEFT(field,len(field)+1-PATINDEX('%[^0-9]%',reverse('0'+field))

If i understand your question, you just want to be able to access items in a data frame (or list) by row:

x = matrix( ceiling(9*runif(20)), nrow=5  )   
colnames(x) = c("col1", "col2", "col3", "col4")
df = data.frame(x)      # create a small data frame

df[1,]                  # get the first row
df[3,]                  # get the third row
df[nrow(df),]           # get the last row

lf = as.list(df)        

lf[[1]]                 # get first row
lf[[3]]                 # get third row

etc.

If you want to get current working directory use getcwd()

http://php.net/manual/en/function.getcwd.php

__FILE__ will return path with filename for example on XAMPP C:\xampp\htdocs\index.php instead of C:\xampp\htdocs\

It's simple, set a specific value for that label (XXXXXXX for example) and run it, open html source of output (in browser) and look for XXXXXXX, you will see something like this <span id="mylabel">XXXXXX</span> it's what you want, the ID of <span> (I think it's usually same as Label name in asp code) now you can get its value by innerHTML or another method in JQuery

Sorry for being late on the party. Depending on your server configuration, You may be required to specify character strictly with lowercase letters utf-8, otherwise it will be ignored. Try this if you end up here searching for solutions and none of answers above helps:

$mail->CharSet = "UTF-8";

should be replaced with:

$mail->CharSet = "utf-8";

If you are using OpenLDAP (i.e. slapd) which is common on Linux servers, then you must enable the memberof overlay to be able to match against a filter using the (memberOf=XXX) attribute.

Also, once you enable the overlay, it does not update the memberOf attributes for existing groups (you will need to delete out the existing groups and add them back in again). If you enabled the overlay to start with, when the database was empty then you should be OK.

One possibility that the above answers don't address is that you may not have an ssh access from your shell. That is, you may be in a network (some college networks do this) where ssh service is blocked.In that case you will not only be able to get github services but also any other ssh services. You can test if this is the problem by trying to use any other ssh service.This was the case with me.

Answering the question at hand...
No it's not enough to have these attributes, to be able to autoplay a media with audio you need to have an user-gesture registered on your document.

But, this limitation is very weak: if you did receive this user-gesture on the parent document, and your video got loaded from an iframe, then you could play it...

So take for instance this fiddle, which is only

<video src="myvidwithsound.webm" autoplay=""></video>

At first load, and if you don't click anywhere, it will not run, because we don't have any event registered yet.
But once you click the "Run" button, then the parent document (jsfiddle.net) did receive an user-gesture, and now the video plays, even though it is technically loaded in a different document.

But the following snippet, since it requires you to actually click the Run code snippet button, will autoplay.

<video src="https://upload.wikimedia.org/wikipedia/commons/transcoded/2/22/Volcano_Lava_Sample.webm/Volcano_Lava_Sample.webm.360p.webm" autoplay=""></video>

This means that your ad was probably able to play because you did provide an user-gesture to the main page.

Now, note that Safari and Mobile Chrome have stricter rules than that, and will require you to actually trigger at least once the play() method programmatically on the <video> or <audio> element from the user-event handler itself.

btn.onclick = e => {_x000D_
  // mark our MediaElement as user-approved_x000D_
  vid.play().then(()=>vid.pause());_x000D_
  // now we can do whatever we want at any time with this MediaElement_x000D_
  setTimeout(()=> vid.play(), 3000);_x000D_
};

<button id="btn">play in 3s</button>_x000D_
<video_x000D_
  src="https://upload.wikimedia.org/wikipedia/commons/transcoded/2/22/Volcano_Lava_Sample.webm/Volcano_Lava_Sample.webm.360p.webm" id="vid"></video>

And if you don't need the audio, then simply don't attach it to your media, a video with only a video track is also allowed to autoplay, and will reduce your user's bandwidth usage.

I never liked using Robot, so I made my own simple method for making screenshots of JFrame objects:

public static final void makeScreenshot(JFrame argFrame) {
    Rectangle rec = argFrame.getBounds();
    BufferedImage bufferedImage = new BufferedImage(rec.width, rec.height, BufferedImage.TYPE_INT_ARGB);
    argFrame.paint(bufferedImage.getGraphics());

    try {
        // Create temp file
        File temp = File.createTempFile("screenshot", ".png");

        // Use the ImageIO API to write the bufferedImage to a temporary file
        ImageIO.write(bufferedImage, "png", temp);

        // Delete temp file when program exits
        temp.deleteOnExit();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }
}

Keep it Simple and use Java 8:-

 Map<String, AccountGroupMappingModel> mapAccountGroup=CustomerDAO.getAccountGroupMapping();
 Map<String, AccountGroupMappingModel> mapH2ToBydAccountGroups = 
              mapAccountGroup.entrySet().stream()
                         .collect(Collectors.toMap(e->e.getValue().getH2AccountGroup(),
                                                   e ->e.getValue())
                                  );

foo.h

#ifndef FOO_H_   /* Include guard */
#define FOO_H_

int foo(int x);  /* An example function declaration */

#endif // FOO_H_

foo.c

#include "foo.h"  /* Include the header (not strictly necessary here) */

int foo(int x)    /* Function definition */
{
    return x + 5;
}

main.c

#include <stdio.h>
#include "foo.h"  /* Include the header here, to obtain the function declaration */

int main(void)
{
    int y = foo(3);  /* Use the function here */
    printf("%d\n", y);
    return 0;
}

To compile using GCC

gcc -o my_app main.c foo.c

Please note the fact that: n&(n-1) always eliminates the least significant 1.

Hence we can write the code for calculating the number of 1's as follows:

count=0;
while(n!=0){
  n = n&(n-1);
  count++;
}
cout<<"Number of 1's in n is: "<<count;

The complexity of the program would be: number of 1's in n (which is constantly < 32).

Assuming that you don't have a library or system header that defines NULL as for example (void*)0 or (char*)0 it's fine. I always tend to use 0 myself as it is by definition the null pointer. In c++0x you'll have nullptr available so the question won't matter as much anymore.

Since this question was originally asked, Google's Guava library now includes a powerful and flexible cache. I would recommend using this.

Did you try to make a cast from date to time?

select cast(getdate() as time)

Reviewing the question, I saw the 'AM/PM' at end. So, my answer for this question is:

select format(getdate(), 'hh:mm:ss tt')

If each pixel is assumed to be of the same area then the following article about converting distances to longitude/latitude co-ordinates may be of some help to you:

Use this:

<input type="button" value="button name" onclick="window.open('http://www.website.com/page')" />

Worked for me and it will open an actual new 'popup' window rather than a new full browser or tab. You can also add variables to it to stop it from showing specific browser traits as follows:

onclick="window.open(this.href,'popUpWindow','height=400,width=600,left=10,top=10,,scrollbars=yes,menubar=no'); return false;"

Encrypting the session value will have zero effect. The session cookie is already an arbitrary value, encrypting it will just generate another arbitrary value that can be sniffed.

The only real solution is HTTPS. If you don't want to do SSL on your whole site (maybe you have performance concerns), you might be able to get away with only SSL protecting the sensitive areas. To do that, first make sure your login page is HTTPS. When a user logs in, set a secure cookie (meaning the browser will only transmit it over an SSL link) in addition to the regular session cookie. Then, when a user visits one of your "sensitive" areas, redirect them to HTTPS, and check for the presence of that secure cookie. A real user will have it, a session hijacker will not.

EDIT: This answer was originally written in 2008. It's 2016 now, and there's no reason not to have SSL across your entire site. No more plaintext HTTP!

I do it this way. Precise? Maybe or maybe not. Try it

<html>
  <head>
    <title> Age Calculator</title>
  </head>

  <input type="date" id="startDate" value="2000-01-01">
  <input type="date" id="endDate"  value="2020-01-01">
  <button onclick="getAge(new Date(document.getElementById('startDate').value), new Date(document.getElementById('endDate').value))">Check Age</button>
  <script>
    function getAge (startDate, endDate) {
      var diff = endDate-startDate
      var age = new Date(new Date("0000-01-01").getTime()+diff)
      var years = age.getFullYear()
      var months = age.getMonth()
      var days = age.getDate()
      console.log(years,"years",months,"months",days-1,"days")
      return (years+"years "+ months+ "months"+ days,"days")
    }
  </script>
</html>

You can also left pad with zeros. For example if you want number to have 9 characters length, left padded with zeros use:

print('{:09.3f}'.format(number))

Thus, if number = 4.656, the output is: 00004.656

For your example the output will look like this:

numbers  = [23.2300, 0.1233, 1.0000, 4.2230, 9887.2000]
for x in numbers: 
    print('{:010.4f}'.format(x))

prints:

00023.2300
00000.1233
00001.0000
00004.2230
09887.2000

One example where this may be useful is when you want to properly list filenames in alphabetical order. I noticed in some linux systems, the number is: 1,10,11,..2,20,21,...

Thus if you want to enforce the necessary numeric order in filenames, you need to left pad with the appropriate number of zeros.

Try switching your JVM to eclipse openj9. Its gonna use way less memory. I swapped it and its using 600Mb constantly.

WITH  q AS
        (
        SELECT TOP 1 *
        FROM    mytable
        /* You may want to add ORDER BY here */
        )
DELETE
FROM    q

Note that

DELETE TOP (1)
FROM   mytable

will also work, but, as stated in the documentation:

The rows referenced in the TOP expression used with INSERT, UPDATE, or DELETE are not arranged in any order.

Therefore, it's better to use WITH and an ORDER BY clause, which will let you specify more exactly which row you consider to be the first.

To static either a row or a column, put a $ sign in front of it. So if you were to use the formula =AVERAGE($A1,$C1) and drag it down the entire sheet, A and C would remain static while the 1 would change to the current row

If you're on Windows, you can achieve the same thing by repeatedly pressing F4 while in the formula editing bar. The first F4 press will static both (it will turn A1 into $A$1), then just the row (A$1) then just the column ($A1)

Although technically with the formulas that you have, dragging down for the entirety of the column shouldn't be a problem without putting a $ sign in front of the column. Setting the column as static would only come into play if you're dragging ACROSS columns and want to keep using the same column, and setting the row as static would be for dragging down rows but wanting to use the same row.

localStorage only supports strings. Use JSON.stringify() and JSON.parse().

var names = [];
names[0] = prompt("New member name?");
localStorage.setItem("names", JSON.stringify(names));

//...
var storedNames = JSON.parse(localStorage.getItem("names"));

Here, try this (assuming it's a small file!):

<?php
echo file_get_contents( "filename.php" ); // get the contents, and echo it out.
?>

Documentation is here.

You want .children() instead (documentation here):

$(this).closest('tr').children('td.two').text();

System.setProperty is not working for applets. Because JVM already running before applet start. In this case we use applet parameters like this:

    deployJava.runApplet({
        id: 'MyApplet',
        code: 'com.mkysoft.myapplet.SomeClass',
        archive: 'com.mkysoft.myapplet.jar'
    }, {
        java_version: "1.6*", // Target version
        cache_option: "no",
        cache_archive: "",
        codebase_lookup: true,
        java_arguments: "-Djava.net.preferIPv4Stack=true"
    },
       "1.6" // Minimum version
    );

You can find deployJava.js at https://www.java.com/js/deployJava.js

As a preliminary (before reimporting everything), here is a solution to recover working sets in which project were (if any).

I had more than 100 projects and each was in one of 14 working sets. If your top level elements changes (accidentaly or not if it is a bug) from "Working set" to "Projects", you only see projects that are NOT in a working set, and if, as I do, you don't have any projects outside a working set, you think all is lost because you cannot see anything (blank package explorer). So the solution is now obvious: click on the top left small white triangle MENU, than select "Top level elements", than select "Working sets". You also have the possibility to rearrange the working sets list items. Hope it helps Unfortunatly the working sets were empty after the recovery, but at least I recovered their names.

It also happens when you have not give enough permissions(read and write) to your sock file!

Just add expected permission to your sock contained folder and your sock file:

 chmod ug+rw /path/to/your/
 chmod ug+rw /path/to/your/file.sock

Then have fun!

The reason that the performance of instanceof and getClass() == ... is different is that they are doing different things.

• instanceof tests whether the object reference on the left-hand side (LHS) is an instance of the type on the right-hand side (RHS) or some subtype.

• getClass() == ... tests whether the types are identical.

So the recommendation is to ignore the performance issue and use the alternative that gives you the answer that you need.

Is using the instanceOf operator bad practice ?

Not necessarily. Overuse of either instanceOf or getClass() may be "design smell". If you are not careful, you end up with a design where the addition of new subclasses results in a significant amount of code reworking. In most situations, the preferred approach is to use polymorphism.

However, there are cases where these are NOT "design smell". For example, in equals(Object) you need to test the actual type of the argument, and return false if it doesn't match. This is best done using getClass().

^{Terms like "best practice", "bad practice", "design smell", "antipattern" and so on should be used sparingly and treated with suspicion. They encourage black-or-white thinking. It is better to make your judgements in context, rather than based purely on dogma; e.g. something that someone said is "best practice". I recommend that everyone read No Best Practices if they haven't already done so.}

It uses commas as separators. So you can either set sep="," or just use read.csv:

x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593      9

The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):

State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582

And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table with the default quote argument (but not read.csv):

01,089,24,033,MD,Prince George's County,13,30,1040

you must use

 < SomeObject xml:space="preserve" > once upon a time ...
      this line will be below the first one < /SomeObject>

Or if you prefer :

 <SomeObject xml:space="preserve" />  once upon a time... &#10; this line below < / SomeObject>

watch out : if you both use &10 AND you go to the next line in your text, you'll have TWO empty lines.

Click on the Window tab in Eclipse, go to Preferences and when that window comes up, go to Java ? Installed JREs ? Execution Environment and choose JavaSE-1.5. You then have to go to Compiler and set the Compiler compliance level.

Why not perform a clone and then delete the .git directory so that you just have a bare working copy?

Edit: Or in fact why use clone at all? It's a bit confusing when you say that you want a git repo but without a .git directory. If you mean that you just want a copy of some state of the tree then why not do cp -R in the shell instead of the git clone and then delete the .git afterwards.

I personally use them in combination. For example:

HTML

<a href="#">Link</a>

with little bit of jQuery

$('a[href="#"]').attr('href','javascript:void(0);');

or

$('a[href="#"]').click(function(e) {
   e.preventDefault();
});

But I'm using that just for preventing the page jumping to the top when the user clicks on an empty anchor. I'm rarely using onClick and other on events directly in HTML.

My suggestion would be to use <span> element with the class attribute instead of an anchor. For example:

<span class="link">Link</span>

Then assign the function to .link with a script wrapped in the body and just before the </body> tag or in an external JavaScript document.

<script>
    (function($) {
        $('.link').click(function() {
            // do something
        });
    })(jQuery);
</script>

*Note: For dynamically created elements, use:

$('.link').on('click', function() {
    // do something
});

And for dynamically created elements which are created with dynamically created elements, use:

$(document).on('click','.link', function() {
    // do something
});

Then you can style the span element to look like an anchor with a little CSS:

.link {
    color: #0000ee;
    text-decoration: underline;
    cursor: pointer;
}
.link:active {
    color: red;
}

Here's a jsFiddle example of above aforementioned.

If your date is already a DateTime or DateTimeImmutable you can use the format method.

$day_of_week = intval($date_time->format('w'));

The format string is identical to the one used by the date function.

To answer the intended question:

$date_time->modify($target_day_of_week - $day_of_week . ' days');

SELECT CAST(Value as Decimal(10,2)) FROM TABLE_NAME;

This is a Bash line that prints all available mac addresses, except the loopback:

for x in `ls /sys/class/net |grep -v lo`; do cat /sys/class/net/$x/address; done

Can be executed from a C program.

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

Try this:

string decodedUrl = HttpUtility.UrlDecode("my.aspx?val=%2Fxyz2F");

just two commands save my life

1. This will list down all previous HEADs

git reflog

2. This will revert the HEAD to commit that you deleted.

git reset --hard <your deleted commit>
ex. git reset --hard b4b2c02

With Python older than 2.7/3.1, that's pretty much how you do it.

For newer versions, see importlib.import_module for Python 2 and and Python 3.

You can use exec if you want to as well.

Or using __import__ you can import a list of modules by doing this:

>>> moduleNames = ['sys', 'os', 're', 'unittest'] 
>>> moduleNames
['sys', 'os', 're', 'unittest']
>>> modules = map(__import__, moduleNames)

Ripped straight from Dive Into Python.

The problem here is the performance, if you have a lot of rows it will be a problem.

If it is your case, please try with this:

import pandas as pd

source = pd.DataFrame({'Country' : ['USA', 'USA', 'Russia','USA'], 
              'City' : ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
              'Short_name' : ['NY','New','Spb','NY']})

source.groupby(['Country','City']).agg(lambda x:x.value_counts().index[0])

source.groupby(['Country','City']).Short_name.value_counts().groupby['Country','City']).first()

Try this for SQL Server:

WITH cte AS (
   SELECT home, MAX(year) AS year FROM Table1 GROUP BY home
)
SELECT * FROM Table1 a INNER JOIN cte ON a.home = cte.home AND a.year = cte.year

A very very good document regarding this topic is Troubleshooting Guide for Java from (originally) Sun. See the chapter "Troubleshooting System Crashes" for information about hs_err_pid* Files.

See Appendix C - Fatal Error Log

Per the guide, by default the file will be created in the working directory of the process if possible, or in the system temporary directory otherwise. A specific location can be chosen by passing in the -XX:ErrorFile product flag. It says:

If the -XX:ErrorFile= file flag is not specified, the system attempts to create the file in the working directory of the process. In the event that the file cannot be created in the working directory (insufficient space, permission problem, or other issue), the file is created in the temporary directory for the operating system.

I know I am late to the show with this one, but I used this - pretty simple approach. This allows you to get the 60 minute slices without any rounding issues.

I've get closer to VisualStudio-like behaviour by setting the "Autocomplete Trigger for Java" to

.(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

and setting delay to 0.

Now I'd like to realize how to make it autocomplete method name when I press ( as VS's Intellisense does.

Also if you run pytest within your virtual environment make sure pytest module is installed within your virtual environment. Activate your virtual env and run pip install pytest.

Just use padding top and bottom, it will automatically center the content vertically.

With this command:

 dpkg -s mysql-server | grep Status

If you want to build a different configuration without regenerating if using you can also run cmake --build {$PWD} --config <cfg> For multi-configuration tools, choose <cfg> ex. Debug, Release, MinSizeRel, RelWithDebInfo

https://cmake.org/cmake/help/v2.8.11/cmake.html#opt%3a--builddir

You can also do this globally via a rcParams dictionary:

import matplotlib.pylab as pylab
params = {'legend.fontsize': 'x-large',
          'figure.figsize': (15, 5),
         'axes.labelsize': 'x-large',
         'axes.titlesize':'x-large',
         'xtick.labelsize':'x-large',
         'ytick.labelsize':'x-large'}
pylab.rcParams.update(params)

Your problem is with this line:

number4 = list(cow[n])

It tries to take cow[n], which returns an integer, and make it a list. This doesn't work, as demonstrated below:

>>> a = 1
>>> list(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>>

Perhaps you meant to put cow[n] inside a list:

number4 = [cow[n]]

See a demonstration below:

>>> a = 1
>>> [a]
[1]
>>>

Also, I wanted to address two things:

1. Your while-statement is missing a : at the end.
2. It is considered very dangerous to use input like that, since it evaluates its input as real Python code. It would be better here to use raw_input and then convert the input to an integer with int.

To split up the digits and then add them like you want, I would first make the number a string. Then, since strings are iterable, you can use sum:

>>> a = 137
>>> a = str(a)
>>> # This way is more common and preferred
>>> sum(int(x) for x in a)
11
>>> # But this also works
>>> sum(map(int, a))
11
>>>

You can use \url

\usepackage{hyperref}
\url{http://stackoverflow.com/}

Suggestions:

• Create a File object that refers to the already existing file on disk.
• Use a FileWriter object, and use the constructor that takes the File object and a boolean, the latter if true would allow appending text into the File if it exists.
• Then initialize a PrintWriter passing in the FileWriter into its constructor.
• Then call println(...) on your PrintWriter, writing your new text into the file.
• As always, close your resources (the PrintWriter) when you are done with it.
• As always, don't ignore exceptions but rather catch and handle them.
• The close() of the PrintWriter should be in the try's finally block.

e.g.,

  PrintWriter pw = null;

  try {
     File file = new File("fubars.txt");
     FileWriter fw = new FileWriter(file, true);
     pw = new PrintWriter(fw);
     pw.println("Fubars rule!");
  } catch (IOException e) {
     e.printStackTrace();
  } finally {
     if (pw != null) {
        pw.close();
     }
  }

Easy, no?

This works for me. use MAX(CONVERT(date, ReportDate)) to make sure you have date value

select max( CONVERT(date, ReportDate)) FROM [TraxHistory]

I like PodTech.io's answer to achieve this without additional tools. For me, it did not run out of the box, so I had to slightly change it. I am not sure if the command wScript.Sleep 12000 (12 sec delay) in the original script is required or not, so I kept it.

Here's the modified script Zip.cmd based on his answer, which works fine on my end:

@echo off   
if "%1"=="" goto end

setlocal
set TEMPDIR=%TEMP%\ZIP
set FILETOZIP=%1
set OUTPUTZIP=%2.zip
if "%2"=="" set OUTPUTZIP=%1.zip

echo Set objZipFile = fso.CreateTextFile(ZipFile, True) >> _zipIt.vbs
echo objZipFile.Write "PK" ^& Chr(5) ^& Chr(6) ^& String(18, vbNullChar) >> _zipIt.vbs

Usage:

• One parameter (no wildcards allowed here):

  Zip FileToZip.txt
  

  will create FileToZip.txt.zip in the same folder containing the zipped file FileToZip.txt.
  
  

• Two parameters (optionally with wildcards for the first parameter), e.g.

  Zip *.cmd Scripts

  creates Scripts.zip in the same folder containing all matching *.cmd files.

something is not right

Well, you are using jQuery to check for the presence of jQuery. If jQuery isn't loaded then $() won't even run at all and your callback won't execute, unless you're using another library and that library happens to share the same $() syntax.

Remove your $(document).ready() (use something like window.onload instead):

window.onload = function() {
    if (window.jQuery) {  
        // jQuery is loaded  
        alert("Yeah!");
    } else {
        // jQuery is not loaded
        alert("Doesn't Work");
    }
}

Use underscore (or loDash :)):

var randomArray = [
   '#cc0000','#00cc00', '#0000cc'
];

// use _.sample
var randomElement = _.sample(randomArray);

// manually use _.random
var randomElement = randomArray[_.random(randomArray.length-1)];

Or to shuffle an entire array:

// use underscore's shuffle function
var firstRandomElement = _.shuffle(randomArray)[0];

WAMP Server – MySQL – Resetting the Root Password (Windows)

1. Log on to your system as Administrator.

2. Click on the Wamp server icon > MySQL > MySQL Console

3. Enter password: LEAVE BLANK AND HIT ENTER

4. mysql> UPDATE mysql.user SET Password=PASSWORD(‘MyNewPass’) WHERE User=’root’; ENTER Query OK

5. mysql>FLUSH PRIVILEGES; ENTER mysql>quit ENTER mysql>bye

6. Edit phpmyadmin file called “config.inc.php” enter ‘MyNewPass’ ($cfg['Servers'][$i]['password'] = ‘MyNewPass‘;)

7. Restart all services

8. Clear all cookies – I got the No password error and it was because of the cookies. (ERROR 1045: Access denied for user: ‘root@localhost’ (Using password: NO))

I just changed:

  <base href="/">

to this:

  <base href="/something.html/">

don't forget ending with /

As ugly as it is, here is a workaround that works as long as you aren't passing an array explicitly, but a variable corresponding to an array:

function passarray()
{
    eval array_internally=("$(echo '${'$1'[@]}')")
    # access array now via array_internally
    echo "${array_internally[@]}"
    #...
}

array=(0 1 2 3 4 5)
passarray array # echo's (0 1 2 3 4 5) as expected

I'm sure someone can come up with a clearner implementation of the idea, but I've found this to be a better solution than passing an array as "{array[@]"} and then accessing it internally using array_inside=("$@"). This becomes complicated when there are other positional/getopts parameters. In these cases, I've had to first determine and then remove the parameters not associated with the array using some combination of shift and array element removal.

A purist perspective likely views this approach as a violation of the language, but pragmatically speaking, this approach has saved me a whole lot of grief. On a related topic, I also use eval to assign an internally constructed array to a variable named according to a parameter target_varname I pass to the function:

eval $target_varname=$"(${array_inside[@]})"

Hope this helps someone.

What is the difference between left join and left outer join?

Nothing. LEFT JOIN and LEFT OUTER JOIN are equivalent.

After setting

 actionBar.setHomeButtonEnabled(true);

You have to configure the parent activity in your AndroidManifest.xml

@Rene Juuse - above in comments... Thanks for this link !

. the code to get the real path is a bit different from one SDK to another so below we have three methods that deals with different SDKs.

getRealPathFromURI_API19(): returns real path for API 19 (or above but not tested) getRealPathFromURI_API11to18(): returns real path for API 11 to API 18 getRealPathFromURI_below11(): returns real path for API below 11

UPDATE 2016 March

To fix all problems with path of images i try create a custom gallery as facebook and other apps. This is because you can use just local files ( real files, not virtual or temporary) , i solve all problems with this library.

https://github.com/nohana/Laevatein (this library is to take photo from camera or choose from galery , if you choose from gallery he have a drawer with albums and just show local files)

The problem with maintenance info sections is that command tries to extract information from the section header of the binary. It does not work if the binary is tripped (e.g by sstrip) or it gives wrong information when the loader may change the memory permission after loading (e.g. the case of RELRO).

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

Start writing, then just press CTRL+SPACE and there you go ...

Adding the correct doctype declaration and avoiding the XML prolog should be enough to avoid quirks mode.

If you dont want your local changes, then do below command to ignore(delete permanently) the local changes.

• If its unstaged changes, then do checkout (git checkout <filename> or git checkout -- .)
• If its staged changes, then first do reset (git reset <filename> or git reset) and then do checkout (git checkout <filename> or git checkout -- .)
• If it is untracted files/folders (newly created), then do clean (git clean -fd)

If you dont want to loose your local changes, then stash it and do pull or rebase. Later merge your changes from stash.

• Do git stash, and then get latest changes from repo git pull orign master or git rebase origin/master, and then merge your changes from stash git stash pop stash@{0}

Go to someplace the namespace is declared in one of your files. Put the cursor on the part of the namespace you want to change, and press F2. This should rename the namespace in every file. At least, it worked in my little demo project I created to test this answer!

Depending on your VS version, the shortcut might also be Ctrl-R,Ctrl-R.

This can be achieved using java.util.Date. The following code will subtract 1 hour from your date.

Date date = new Date(yourdate in date format);
Date newDate = DateUtils.addHours(date, -1)

Similarly for subtracting 20 seconds from your date

newDate = DateUtils.addSeconds(date, -20)    

First of all, don't use char* or char[N]. Use std::string, then everything else becomes so easy!

Examples,

std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!

Easy, isn't it?

Now if you need char const * for some reason, such as when you want to pass to some function, then you can do this:

some_c_api(s.c_str(), s.size()); 

assuming this function is declared as:

some_c_api(char const *input, size_t length);

Explore std::string yourself starting from here:

• Documentation of std::string

Hope that helps.

For those of you using pytest with mocker here is how I mocked datetime.datetime.now() which is very similar to the original question.

test_get_now(mocker):
    datetime_mock = mocker.patch("blackline_accounts_import.datetime",)
    datetime_mock.datetime.now.return_value=datetime.datetime(2019,3,11,6,2,0,0)

    now == function_being_tested()  # run function

    assert now == datetime.datetime(2019,3,11,6,2,0,0)

Essentially the mock has to be set to return the specified date. You aren't able to patch over datetime's object directly.

Use value(cellref) on the side to evaluate the cells. Strings will produce the "#Value" error, but dates resolve to a number (e.g. 43173).

Although overloading paradigm is not fully supported by PHP the same (or very similar) effect can be achieved with default parameter(s) (as somebody mentioned before).

If you define your function like this:

function f($p=0)
{
  if($p)
  {
    //implement functionality #1 here
  }
  else
  {
    //implement functionality #2 here
  }
}

When you call this function like:

f();

you'll get one functionality (#1), but if you call it with parameter like:

f(1);

you'll get another functionality (#2). That's the effect of overloading - different functionality depending on function's input parameter(s).

I know, somebody will ask now what functionality one will get if he/she calls this function as f(0).

Using en-CA as an example, if you're using date-fns:

<script type="module">
  import { enCA } from 'https://cdn.skypack.dev/date-fns/locale';
  console.log(enCA.formatLong.date({width:'short'}))
  // yyyy-MM-dd
</script>

Source: https://github.com/date-fns/date-fns/blob/master/src/locale/en-CA/_lib/formatLong/index.js

For CLDR & Paul Irish:

import locale from 'cldr-dates-modern/main/en-CA/ca-gregorian.json'
console.log(locale.main['en-CA'].dates.calendars.gregorian.dateFormats.short)
// y-MM-dd

I Prefer these one:

Creates Bitmap from InputStream and returns it:

    public static  Bitmap downloadImage(String url) {
        Bitmap bitmap = null;
        InputStream stream = null;
        BitmapFactory.Options bmOptions = new BitmapFactory.Options();
        bmOptions.inSampleSize = 1;

        try {
            stream = getHttpConnection(url);
            bitmap = BitmapFactory.decodeStream(stream, null, bmOptions);
            stream.close();
        }
        catch (IOException e1) {
            e1.printStackTrace();
            System.out.println("downloadImage"+ e1.toString());
        }
        return bitmap;
    }

  // Makes HttpURLConnection and returns InputStream

 public static  InputStream getHttpConnection(String urlString)  throws IOException {

        InputStream stream = null;
        URL url = new URL(urlString);
        URLConnection connection = url.openConnection();

        try {
            HttpURLConnection httpConnection = (HttpURLConnection) connection;
            httpConnection.setRequestMethod("GET");
            httpConnection.connect();

            if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
                stream = httpConnection.getInputStream();
            }
        }
        catch (Exception ex) {
            ex.printStackTrace();
            System.out.println("downloadImage" + ex.toString());
        }
        return stream;
    }

REMEMBER :

Android includes two HTTP clients: HttpURLConnection and Apache HTTP Client. For Gingerbread and later, HttpURLConnection is the best choice.

From Android 3.x Honeycomb or later, you cannot perform Network IO on the UI thread and doing this throws android.os.NetworkOnMainThreadException. You must use Asynctask instead as shown below

/**     AsyncTAsk for Image Bitmap  */
    private class AsyncGettingBitmapFromUrl extends AsyncTask<String, Void, Bitmap> {


        @Override
        protected Bitmap doInBackground(String... params) {

            System.out.println("doInBackground");

            Bitmap bitmap = null;

            bitmap = AppMethods.downloadImage(params[0]);

            return bitmap;
        }

        @Override
        protected void onPostExecute(Bitmap bitmap) {

            System.out.println("bitmap" + bitmap);

        }
    }

Sending from a third party SMTP isn't restricted by or specific to Azure. Using System.Net.Mail, create your message, configure your SMTP client, send the email:

// create the message
var msg = new MailMessage();
msg.From = new MailAddress("[email protected]"); 
msg.To.Add(strTo); 
msg.Subject = strSubject; 
msg.IsBodyHtml = true; 
msg.Body = strMessage;

// configure the smtp server
var smtp = new SmtpClient("YourSMTPServer"); 
var = new System.Net.NetworkCredential("YourSMTPServerUserName", "YourSMTPServerPassword");

// send the message
smtp.Send(msg); 

UPDATE: I added a post on Medium about how to do this with an Azure Function - https://medium.com/@viperguynaz/building-a-serverless-contact-form-f8f0bff46ba9

Sometime, in Xcode 8 you might find yourself in a revoke-regenerate cycle, where you let Xcode 8 "fix" the certificates and provisioning, then Xcode finds the new/regenerated certificates to be invalid also, and you go back to revoke, and it keeps happening.

In such cases, check your MacOS time! If you have it set to some other time, not the real current time, the new certificate may always "not yet" be valid.

To animate your 3D object, use the code:

<script>

$(document).ready(function(){

    var x = 100;
    var y = 0;
setInterval(function(){
    x += 1;
    y += 1;
    var element = document.getElementById('cube');
    element.style.webkitTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for safari and chrome
    element.style.MozTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for firefox
},50);
//for other browsers use:   "msTransform",    "OTransform",    "transform"

});

</script>

You'll need to put your current query in subquery as below :

SELECT * FROM (
  SELECT DISTINCT 
  APP_ID, 
  NAME, 
  STORAGE_GB, 
  HISTORY_CREATED, 
  TO_CHAR(HISTORY_DATE, 'DD.MM.YYYY') AS HISTORY_DATE  
  FROM HISTORY WHERE 
    STORAGE_GB IS NOT NULL AND 
      APP_ID NOT IN (SELECT APP_ID FROM HISTORY WHERE TO_CHAR(HISTORY_DATE, 'DD.MM.YYYY') ='06.02.2009')
  ORDER BY STORAGE_GB DESC )
WHERE ROWNUM <= 10

Oracle applies rownum to the result after it has been returned.
You need to filter the result after it has been returned, so a subquery is required. You can also use RANK() function to get Top-N results.

For performance try using NOT EXISTS in place of NOT IN. See this for more.

I find the easiest way is to double up on the quotes to handle a quote.

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0,"""",Sheet1!A1)" 

Some people like to use CHR(34)*:

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0," & CHR(34) & CHR(34) & ",Sheet1!A1)" 

*Note: CHAR() is used as an Excel cell formula, e.g. writing "=CHAR(34)" in a cell, but for VBA code you use the CHR() function.

Here an alternative using SUBSTRING

SELECT
            SUBSTRING([Field], LEN([Field]) - 2, 3) [Right3],
            SUBSTRING([Field], 0, LEN([Field]) - 2) [TheRest]
    FROM 
            [Fields]

Shells are the glue of Linux

Linux shells like sh/ksh/bash/... provide input/output/flow-control designation facilities much like the old mainframe Job Control Language... but on steroids! They are Turing complete languages in their own right while being optimized to efficiently pass data and control to and from other executing processes written in any language the O/S supports.

Most Linux applications, regardless what language the bulk of the program is written in, depend on shell scripts and Bash has become the most common. Clicking an icon on the desktop usually runs a short Bash script. That script, either directly or indirectly, knows where all the files needed are and sets variables and command line parameters, finally calling the program. That's a shell's simplest use.

Linux as we know it however would hardly be Linux without the thousands of shell scripts that startup the system, respond to events, control execution priorities and compile, configure and run programs. Many of these are quite large and complex.

Shells provide an infrastructure that lets us use pre-built components that are linked together at run time rather than compile time. Those components are free-standing programs in their own right that can be used alone or in other combinations without recompiling. The syntax for calling them is indistinguishable from that of a Bash builtin command, and there are in fact numerous builtin commands for which there is also a stand-alone executable on the system, often having additional options.

There is no language-wide difference between Python and Bash in performance. It entirely depends on how each is coded and which external tools are called.

Any of the well known tools like awk, sed, grep, bc, dc, tr, etc. will leave doing those operations in either language in the dust. Bash then is preferred for anything without a graphical user interface since it is easier and more efficient to call and pass data back from a tool like those with Bash than Python.

Performance

It depends on which programs the Bash shell script calls and their suitability for the subtask they are given whether the overall throughput and/or responsiveness will be better or worse than the equivalent Python. To complicate matters Python, like most languages, can also call other executables, though it is more cumbersome and thus not as often used.

User Interface

One area where Python is the clear winner is user interface. That makes it an excellent language for building local or client-server applications as it natively supports GTK graphics and is far more intuitive than Bash.

Bash only understands text. Other tools must be called for a GUI and data passed back from them. A Python script is one option. Faster but less flexible options are the binaries like YAD, Zenity, and GTKDialog.

While shells like Bash work well with GUIs like Yad, GtkDialog (embedded XML-like interface to GTK+ functions), dialog, and xmessage, Python is much more capable and so better for complex GUI windows.

Summary

Building with shell scripts is like assembling a computer with off-the-shelf components the way desktop PCs are.

Building with Python, C++ or most any other language is more like building a computer by soldering the chips (libraries) and other electronic parts together the way smartphones are.

The best results are usually obtained by using a combination of languages where each can do what they do best. One developer calls this "polyglot programming".

For modern browsers, use td:nth-child(2) for the second td, and td:nth-child(3) for the third. Remember that these retrieve the second and third td for every row.

If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.

You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.

I've just done this in a grunt project of ours. We needed a newer version of connect, since 2.7.3. was causing trouble for us. So I created a file named npm-shrinkwrap.json:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

npm should automatically pick it up while doing the install for the project.

(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)

I have use below code to encode the special character by specifying encode format.

String text = "This is an example é";
byte[] byteText = text.getBytes(Charset.forName("UTF-8"));
//To get original string from byte.
String originalString= new String(byteText , "UTF-8");

Check your Entity class. Use String instead of Long and float instead of double .

You could do this:

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%MyColumn%'
ORDER BY schema_name, table_name;

The correct way to do this if you want to maintain the default transport settings is now (as of Go 1.13):

customTransport := http.DefaultTransport.(*http.Transport).Clone()
customTransport.TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
client = &http.Client{Transport: customTransport}

Transport.Clone makes a deep copy of the transport. This way you don't have to worry about missing any new fields that get added to the Transport struct over time.

#include <sstream> and use the fully qualified name i.e. std::stringstream ss;

Also, you may try the getUserMedia method (supported by Opera 12)

You can do this simply by using pandas drop duplicates function

df.drop_duplicates(['A','B'],keep= 'last')

To populate the column during insert, use a DEFAULT value:

CREATE TABLE users (
  id serial not null,
  firstname varchar(100),
  middlename varchar(100),
  lastname varchar(100),
  email varchar(200),
  timestamp timestamp default current_timestamp
)

Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT statement. If you want to prevent that you do need a trigger.

You also need a trigger if you need to update that column whenever the row is updated (as mentioned by E.J. Brennan)

Note that using reserved words for column names is usually not a good idea. You should find a different name than timestamp

The only three literal characters which are treated specially in the replace clause are / (to close the clause), \ (to escape characters, backreference, &c.), and & (to include the match in the replacement). Therefore, all you need to do is escape those three characters:

sed "s/KEYWORD/$(echo $REPLACE | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')/g"

Example:

$ export REPLACE="'\"|\\/><&!"
$ echo fooKEYWORDbar | sed "s/KEYWORD/$(echo $REPLACE | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')/g"
foo'"|\/><&!bar

The ultimate solution would be setting overflow: hidden; on document.documentElement like so:

/* element is an HTML element You want catch the touch */
element.addEventListener('touchstart', function(e) {
    document.documentElement.style.overflow = 'hidden';
});

document.addEventListener('touchend', function(e) {
    document.documentElement.style.overflow = 'auto';
});

By setting overflow: hidden on start of touch it makes everything exceeding window hidden thus removing availability to scroll anything (no content to scroll).

After touchend the lock can be freed by setting overflow to auto (the default value).

It is better to append this to <html> because <body> may be used to do some styling, plus it can make children behave unexpectedly.

EDIT: About touch-action: none; - Safari doesn't support it according to MDN.

To anyone who is still interested in this question: If: 1-decodeByteArray returns null 2-Base64.decode throws bad-base64 Exception

Here is the solution: -You should consider the value sent to you from API is Base64 Encoded and should be decoded first in order to cast it to a Bitmap object! -Take a look at your Base64 encoded String, If it starts with

data:image/jpg;base64

The Base64.decode won't be able to decode it, So it has to be removed from your encoded String:

final String encodedString = "data:image/jpg;base64, ....";                        
final String pureBase64Encoded = encodedString.substring(encodedString.indexOf(",")  + 1);

Now the pureBase64Encoded object is ready to be decoded:

final byte[] decodedBytes = Base64.decode(pureBase64Encoded, Base64.DEFAULT);

Now just simply use the line below to turn this into a Bitmap Object! :

Bitmap decodedBitmap = BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);

Or if you're using the great library Glide:

Glide.with(CaptchaFragment.this).load(decodedBytes).crossFade().fitCenter().into(mCatpchaImageView);

This should do the job! It wasted one day on this and came up to this solution!

Note: If you are still getting bad-base64 error consider other Base64.decode flags like Base64.URL_SAFE and so on

You can set a batch/environment variable as follows:

SET var=%cd%
ECHO %var%

ODBC works only for relational databases, it can't works with non-relational databases such as Ms Excel files. Where Olebd can do everything.

Suppose you have:

var j = {0: "1", 1: "2", 2: "3", 3: "4"};

You could get the values with (supported in practically all browser versions):

Object.keys(j).map(function(_) { return j[_]; })

or simply:

Object.values(j)

Output:

["1", "2", "3", "4"]

I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready

opened the httpd.conf and changed the listen port from 80 to 1234 in both places

Listen 12.34.56.78:1234

Listen 1234

Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234

That worked.

Try this as the command string in Task Scheduler:

cmd /c yourscript.cmd > logall.txt

In some cases this is the best way because your code may have change something and j=i+1 won't check that.

for (int i = 0; i < list.size(); i++){  
    for (int j = 0; j < list.size(); j++) {
                if(i == j) {
               //to do code here
                    continue;
                }

}

}

I'd recommend NPOI. NPOI is FREE and works exclusively with .XLS files. It has helped me a lot.

Detail: you don't need to have Microsoft Office installed on your machine to work with .XLS files if you use NPOI.

Check these blog posts:

Creating Excel spreadsheets .XLS and .XLSX in C#

NPOI with Excel Table and dynamic Chart

[UPDATE]

NPOI 2.0 added support for XLSX and DOCX.

The question is slightly ambiguous, since None can translate into either undefined or null. null is a better choice:

var a = [], b;
var i, j;
for (i = 0; i < 9; i++) {
  for (j = 0, b = []; j < 9; j++) {
    b.push(null);
  }
  a.push(b);
}

If undefined, you can be sloppy and just don't bother, everything is undefined anyway. :)

I had the same problem.

Also make sure you are using right python version and you are installing it with right pip version. in my case: I had both python 2.7 and 3.x. I have installed pyspark with

pip2.7 install pyspark

and it worked.

@eljenso : intrafest-servlet.xml webapplication context xml will be used if the application uses SPRING WEB MVC.

Otherwise the @kosoant configuration is fine.

Simple example if you dont use SPRING WEB MVC, but want to utitlize SPRING IOC :

In web.xml:

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:application-context.xml</param-value>
</context-param>

Then, your application-context.xml will contain: <import resource="foo-services.xml"/> these import statements to load various application context files and put into main application-context.xml.

Thanks and hope this helps.

Corrected as of 25.06.2019:

var newDate = new Date(date.setMonth(date.getMonth()+8));

Old From here:

var jan312009 = new Date(2009, 0, 31);
var eightMonthsFromJan312009  = jan312009.setMonth(jan312009.getMonth()+8);

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook

      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"

      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Undoubtly this can be simplified but the results match your expectations.

The gist of this is to

• Calculate the maximum price in a seperate CTE for each t2ID
• Calculate the total price in a seperate CTE for each t2ID
• Combine the results of both CTE's

SQL Statement

;WITH MaxPrice AS ( 
    SELECT  t2ID
            , t1ID
    FROM    (

            ) maxt1
    WHERE   maxt1.rn = 1                            
)
, SumPrice AS (
    SELECT  t2ID = t2.ID
            , Price = SUM(Price)
    FROM    @t1 t1
            INNER JOIN @relation r ON r.t1ID = t1.ID
            INNER JOIN @t2 t2 ON t2.ID = r.t2ID
    GROUP BY
            t2.ID           
)           
SELECT  t2.ID
        , t2.Name

If you only need it once, it's overkill to load a plugin.

For a date "dd/mm/yyyy", this works for me:

new Date(d.date.substring(6, 10),d.date.substring(3, 5)-1,d.date.substring(0, 2));

Just invert month and day for mm/dd/yyyy, the syntax is new Date(y,m,d)

As already stated by Jason Cohen, the Java Language Specification defines what a legal identifier is in section 3.8:

"An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. [...] A 'Java letter' is a character for which the method Character.isJavaIdentifierStart(int) returns true. A 'Java letter-or-digit' is a character for which the method Character.isJavaIdentifierPart(int) returns true."

This hopefully answers your second question. Regarding your first question; I've been taught both by teachers and (as far as I can remember) Java compilers that a Java class name should be an identifier that begins with a capital letter A-Z, but I can't find any reliable source on this. When trying it out with OpenJDK there are no warnings when beginning class names with lower-case letters or even a $-sign. When using a $-sign, you do have to escape it if you compile from a bash shell, however.

onMeasure() is your opportunity to tell Android how big you want your custom view to be dependent the layout constraints provided by the parent; it is also your custom view's opportunity to learn what those layout constraints are (in case you want to behave differently in a match_parent situation than a wrap_content situation). These constraints are packaged up into the MeasureSpec values that are passed into the method. Here is a rough correlation of the mode values:

• EXACTLY means the layout_width or layout_height value was set to a specific value. You should probably make your view this size. This can also get triggered when match_parent is used, to set the size exactly to the parent view (this is layout dependent in the framework).
• AT_MOST typically means the layout_width or layout_height value was set to match_parent or wrap_content where a maximum size is needed (this is layout dependent in the framework), and the size of the parent dimension is the value. You should not be any larger than this size.
• UNSPECIFIED typically means the layout_width or layout_height value was set to wrap_content with no restrictions. You can be whatever size you would like. Some layouts also use this callback to figure out your desired size before determine what specs to actually pass you again in a second measure request.

The contract that exists with onMeasure() is that setMeasuredDimension() MUST be called at the end with the size you would like the view to be. This method is called by all the framework implementations, including the default implementation found in View, which is why it is safe to call super instead if that fits your use case.

Granted, because the framework does apply a default implementation, it may not be necessary for you to override this method, but you may see clipping in cases where the view space is smaller than your content if you do not, and if you lay out your custom view with wrap_content in both directions, your view may not show up at all because the framework doesn't know how large it is!

Generally, if you are overriding View and not another existing widget, it is probably a good idea to provide an implementation, even if it is as simple as something like this:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    int desiredWidth = 100;
    int desiredHeight = 100;

    int widthMode = MeasureSpec.getMode(widthMeasureSpec);
    int widthSize = MeasureSpec.getSize(widthMeasureSpec);
    int heightMode = MeasureSpec.getMode(heightMeasureSpec);
    int heightSize = MeasureSpec.getSize(heightMeasureSpec);

    int width;
    int height;

    //Measure Width
    if (widthMode == MeasureSpec.EXACTLY) {
        //Must be this size
        width = widthSize;
    } else if (widthMode == MeasureSpec.AT_MOST) {
        //Can't be bigger than...
        width = Math.min(desiredWidth, widthSize);
    } else {
        //Be whatever you want
        width = desiredWidth;
    }

    //Measure Height
    if (heightMode == MeasureSpec.EXACTLY) {
        //Must be this size
        height = heightSize;
    } else if (heightMode == MeasureSpec.AT_MOST) {
        //Can't be bigger than...
        height = Math.min(desiredHeight, heightSize);
    } else {
        //Be whatever you want
        height = desiredHeight;
    }

    //MUST CALL THIS
    setMeasuredDimension(width, height);
}

Hope that Helps.

It appears that SSRS has an issue(at leastin version 2008) - I'm studying this website that explains it

Where it says if you have two columns(from 2 diff. tables) with the same name, then it'll cause that problem.

From source:

SELECT a.Field1, a.Field2, a.Field3, b.Field1, b.field99 FROM TableA a JOIN TableB b on a.Field1 = b.Field1

SQL handled it just fine, since I had prefixed each with an alias (table) name. But SSRS uses only the column name as the key, not table + column, so it was choking.

The fix was easy, either rename the second column, i.e. b.Field1 AS Field01 or just omit the field all together, which is what I did.

Expanding on what others have said I will give a short example.

If you have a 1D array ...

>>> import numpy as np
>>> x = np.arange(4) # array([0, 1, 2, 3])
>>> x[::-1] # returns a view
Out[1]: 
array([3, 2, 1, 0])

But if you are working with a 2D array ...

>>> x = np.arange(10).reshape(2, 5)
>>> x
Out[2]:
array([[0, 1, 2, 3, 4],
       [5, 6, 7, 8, 9]])

>>> x[::-1] # returns a view:
Out[3]: array([[5, 6, 7, 8, 9],
               [0, 1, 2, 3, 4]])

This does not actually reverse the Matrix.

Should use np.flip to actually reverse the elements

>>> np.flip(x)
Out[4]: array([[9, 8, 7, 6, 5],
               [4, 3, 2, 1, 0]])

If you want to print the elements of a matrix one-by-one use flat along with flip

>>> for el in np.flip(x).flat:
>>>     print(el, end = ' ')
9 8 7 6 5 4 3 2 1 0

There seems to be multiple modules to do that, some are deprecated.

This one looks active:
https://github.com/jshttp/basic-auth

Here's a use example:

// auth.js

var auth = require('basic-auth');

var admins = {
  '[email protected]': { password: 'pa$$w0rd!' },
};


module.exports = function(req, res, next) {

  var user = auth(req);
  if (!user || !admins[user.name] || admins[user.name].password !== user.pass) {
    res.set('WWW-Authenticate', 'Basic realm="example"');
    return res.status(401).send();
  }
  return next();
};




// app.js

var auth = require('./auth');
var express = require('express');

var app = express();

// ... some not authenticated middlewares

app.use(auth);

// ... some authenticated middlewares

Make sure you put the auth middleware in the correct place, any middleware before that will not be authenticated.

    $message = "This is test message that contain filter world test3";

    $filterWords = array('test1', 'test2', 'test3');

    $messageAfterFilter =  str_replace($filterWords, '',$message);

    if( strlen($messageAfterFilter) != strlen($message) )
        echo 'message is filtered';
    else
        echo 'not filtered';

In Symfony 2 ( to be more specific, the 2.3 version ) you can get a data of an field by

$var = $form->get('yourformfieldname')->getData();

or you can get all data sent

$data = $form->getData();

where '$data' is an array containing your form fields' values.

IF d was created by Newtonsoft you can use this to read property names and values:

    foreach (JProperty property in d)
    {
        DoSomething(property.Name, property.Value);
    }

Git 1.8.2 added the possibility to track branches.

# add submodule to track branch_name branch
git submodule add -b branch_name URL_to_Git_repo optional_directory_rename

# update your submodule
git submodule update --remote 

See also Git submodules

I think this will help

    <directoryBrowse enabled="false" />
    <defaultDocument>
      <files>
        <clear />
        <add value="index.aspx" />
        <add value="Default.htm" />
        <add value="Default.asp" />
        <add value="index.htm" />
        <add value="index.html" />
        <add value="iisstart.htm" />
        <add value="default.aspx" />
        <add value="index.php" />
      </files>
    </defaultDocument>
  </system.webServer>

In Python 3, urllib.quote has been moved to urllib.parse.quote and it does handle unicode by default.

>>> from urllib.parse import quote
>>> quote('/test')
'/test'
>>> quote('/test', safe='')
'%2Ftest'
>>> quote('/El Niño/')
'/El%20Ni%C3%B1o/'

This is the tip provided to resolve the issue which does not work:

Tip - If your instance doesn't have a public DNS name, open the VPC console, select the VPC, and check the Summary tab. If either DNS resolution or DNS hostnames is no, click Edit and change the value to yes.

Assuming you have done this and you are still not getting a Public IP then go over to the subnet in question in the VPC admin screen and you will probably discover "Auto-Assign Public IP" is not set to yes. Modify that setting then, and I know you don't want to here this, create a new instance in that subnet. As far as I can tell you cannot modify this on the host, I tried and tried, just terminate it.

You could try a subquery:

SELECT DISTINCT TEST.* FROM (
    SELECT rsc.RadioServiceCodeId,
        rsc.RadioServiceCode + ' - ' + rsc.RadioService as RadioService
    FROM sbi_l_radioservicecodes rsc
       INNER JOIN sbi_l_radioservicecodegroups rscg ON  rsc.radioservicecodeid = rscg.radioservicecodeid
    WHERE rscg.radioservicegroupid IN 
       (select val from dbo.fnParseArray(@RadioServiceGroup,','))
        OR @RadioServiceGroup IS NULL  
    ORDER BY rsc.RadioServiceCode,rsc.RadioServiceCodeId,rsc.RadioService
) as TEST

I know this may be obvious for most people who use RegEx frequently, but in case any readers are new to RegEx, I thought I should point out an observation I made that was helpful for one of my projects.

In a previous answer from @kennytm:

^\d{5}(?:[-\s]\d{4})?$

…? = The pattern before it is optional (for condition 1)

If you want to allow both standard 5 digit and +4 zip codes, this is a great example.

To match only zip codes in the US 'Zip + 4' format as I needed to do (conditions 2 and 3 only), simply remove the last ? so it will always match the last 5 character group.

A useful tool I recommend for tinkering with RegEx is linked below:

https://regexr.com/

I use this tool frequently when I find RegEx that does something similar to what I need, but could be tailored a bit better. It also has a nifty RegEx reference menu and informative interface that keeps you aware of how your changes impact the matches for the sample text you entered.

If I got anything wrong or missed an important piece of information, please correct me.

You can extend jQuery functionality like this :

Extend :

(function($){
    jQuery.fn.checkEmpty = function() {
       return !$.trim(this.html()).length;
    };
}(jQuery));

Use :

<div id="selector"></div>

if($("#selector").checkEmpty()){
     console.log("Empty");
}else{
     console.log("Not Empty");
}

I'm using Cors 5.1.0.0, after much headache, I discovered the issue to be duplicated Access-Control-Allow-Origin & Access-Control-Allow-Header headers from the server

Removed config.EnableCors() from the WebApiConfig.cs file and just set the [EnableCors("*","*","*")] attribute on the Controller class

If you are running your application on Microsoft Windows, the path to dynamic libraries (.dll) need to be defined in the PATH environment variable.

If you are running your application on UNIX, the path to your dynamic libraries (.so) need to be defined in the LD_LIBRARY_PATH environment variable.

I had the same problem and I am using iPython. pip or conda by itself did not work for me but when I use !conda it did work.

!conda install seaborn

Note: With ConcurrentMap you can use the more efficient

values.putIfAbsent(NoteColumns.CREATED_DATE, now);

I prefer the less verbose solution and avoid methods like IsTrue or IsFalse or their like.

WARNING : JinJs is not maintained anymore. It is still working but not compatible with the lastest version of express.

You could try using jinjs. It is a port of the Jinja, a very good Python templating system. You can install it with npm like this :

npm install jinjs

in template.tpl :

I say : "{{ sentence }}"

in your template.js :

jinjs = require('jinjs');
jinjs.registerExtension('.tpl');
tpl = require('./template');
str = tpl.render ({sentence : 'Hello, World!'});
console.log(str);

The output will be :

I say : "Hello, World!"

We are actively developing it, a good documentation should come pretty soon.

for current year we can use getFullYear() from Date class however there are many function which you can use as per the requirements, some functions are as,

var now = new Date()_x000D_
console.log("Current Time is: " + now);_x000D_
_x000D_
// getFullYear function will give current year _x000D_
var currentYear = now.getFullYear()_x000D_
console.log("Current year is: " + currentYear);_x000D_
_x000D_
// getYear will give you the years after 1990 i.e currentYear-1990_x000D_
var year = now.getYear()_x000D_
console.log("Current year is: " + year);_x000D_
_x000D_
// getMonth gives the month value but months starts from 0_x000D_
// add 1 to get actual month value _x000D_
var month = now.getMonth() + 1_x000D_
console.log("Current month is: " + month);_x000D_
_x000D_
// getDate gives the date value_x000D_
var day = now.getDate()_x000D_
console.log("Today's day is: " + day);

Wildcards can only be used in the ServerAlias rather than the ServerName. Something which had me stumped.

For your use case, the following should suffice

<VirtualHost *:80>
    ServerAlias *.example.com
    VirtualDocumentRoot /var/www/%1/
</VirtualHost>

From near the beginning of the PIL Tutorial:

Once you have an instance of the Image class, you can use the methods defined by this class to process and manipulate the image. For example, let's display the image we just loaded:

     >>> im.show()

Update:

Nowadays theImage.show() method is formally documented in the Pillow fork of PIL along with an explanation of how it's implemented on different OSs.

Easiest method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

Pythonic and elegant way:

objects = [1, 2, 3, 4, 5]
value = 3
if value in objects:
   index = objects.index(value)
   previous_value = objects[index-1]
   next_value = objects[index+1] if index + 1 < len(objects) else None

First off, please note that I haven't used either of them (but have used Node.js).

Both libraries are documented quite well and have a stable API. However, persistence.js seems to be used in more projects. I don't know if all of them still use it, though.

The developer of sequelize sometimes blogs about it at blog.depold.com. When you'd like to use primary keys as foreign keys, you'll need the patch that's described in this blog post. If you'd like help for persistence.js there is a google group devoted to it.

From the examples I gather that sequelize is a bit more JavaScript-like (more sugar) than persistance.js but has support for fewer datastores (only MySQL, while persistance.js can even use in-browser stores).

I think that sequelize might be the way to go for you, as you only need MySQL support. However, if you need some convenient features (for instance search) or want to use a different database later on you'd need to use persistence.js.

It sounds like what you want is a User who has many Questions.
The Question has many Answers, one of which is the User's Choice.

Is this what you are after?

I would model something like that along these lines:

class User
  has_many :questions
end

class Question
  belongs_to :user
  has_many   :answers
  has_one    :choice, :class_name => "Answer"

  validates_inclusion_of :choice, :in => lambda { answers }
end

class Answer
  belongs_to :question
end

You're on the right track. Here's a corrected version:

char str[10];
int n;

printf("type a string: ");
scanf("%s %d", str, &n);

printf("%s\n", str);
printf("%d\n", n);

Let's talk through the changes:

1. allocate an int (n) to store your number in
2. tell scanf to read in first a string and then a number (%d means number, as you already knew from your printf

That's pretty much all there is to it. Your code is a little bit dangerous, still, because any user input that's longer than 9 characters will overflow str and start trampling your stack.

For Travers an String you can also use charAt() with the string.

like :

String str = "xyz"; // given String
char st = str.charAt(0); // for example we take 0 index element 
System.out.println(st); // print the char at 0 index 

charAt() is method of string handling in java which help to Travers the string for specific character.

If you want to use a programmatic approach instead of using ProGuard, then by creating your own class with two instances, one for debug and one for release, you can choose what to log in either circumstances.

So, if you don't want to log anything when in release, simply implement a Logger that does nothing, like the example below:

import android.util.Log

sealed class Logger(defaultTag: String? = null) {
    protected val defaultTag: String = defaultTag ?: "[APP-DEBUG]"

    abstract fun log(string: String, tag: String = defaultTag)

    object LoggerDebug : Logger() {
        override fun log(string: String, tag: String) {
            Log.d(tag, string)
        }
    }

    object LoggerRelease : Logger() {
        override fun log(string: String, tag: String) {}
    }

    companion object {
        private val isDebugConfig = BuildConfig.DEBUG

        val instance: Logger by lazy {
            if(isDebugConfig)
            LoggerDebug
            else
                LoggerRelease
        }

    }
}

Then to use your logger class:

class MainActivity : AppCompatActivity() {

private val logger = Logger.instance

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    logger.log("Activity launched...")
    ...
    myView.setOnClickListener {
        ...

        logger.log("My View clicked!", "View-click")
    }
}

== UPDATE ==

If we want to avoid string concatenations for better performances, we can add an inline function with a lambda that will be called only in debug config:

// Add this function to the Logger class.
inline fun commit(block: Logger.() -> Unit) {
    if(this is LoggerDebug)
        block.invoke(this)
}

And then:

 logger.commit {
     log("Logging without $myVar waste of resources"+ "My fancy concat")
 }

Since we are using an inline function, there are no extra object allocation and no extra virtual method calls.

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

You might be able to make use of sql.js.

sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. no C bindings or node-gyp compilation here.

<script src='js/sql.js'></script>
<script>
    //Create the database
    var db = new SQL.Database();
    // Run a query without reading the results
    db.run("CREATE TABLE test (col1, col2);");
    // Insert two rows: (1,111) and (2,222)
    db.run("INSERT INTO test VALUES (?,?), (?,?)", [1,111,2,222]);

    // Prepare a statement
    var stmt = db.prepare("SELECT * FROM test WHERE col1 BETWEEN $start AND $end");
    stmt.getAsObject({$start:1, $end:1}); // {col1:1, col2:111}

    // Bind new values
    stmt.bind({$start:1, $end:2});
    while(stmt.step()) { //
        var row = stmt.getAsObject();
        // [...] do something with the row of result
    }
</script>

sql.js is a single JavaScript file and is about 1.5MiB in size currently. While this could be a problem in a web-page, the size is probably acceptable for an extension.

DriverManager is a fairly old way of doing things. The better way is to get a DataSource, either by looking one up that your app server container already configured for you:

Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("java:comp/env/jdbc/myDB");

or instantiating and configuring one from your database driver directly:

MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setUser("scott");
dataSource.setPassword("tiger");
dataSource.setServerName("myDBHost.example.org");

and then obtain connections from it, same as above:

Connection conn = dataSource.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT ID FROM USERS");

rs.close();
stmt.close();

Also, you could try triggering a mouseover.

$("#btn").click(function() {
   $("#link").trigger("mouseover");
});

Not sure if this will work for your specific scenario, but I've had success triggering mouseover instead of hover for various cases.

Extending the accepted responses, when you are using JSON in a REST context...

There is a strong argument about using application/x-resource+json and application/x-collection+json when you are representing REST resources and collections.

And if you decide to follow the jsonapi specification, you should use of application/vnd.api+json, as it is documented.

Altough there is not an universal standard, it is clear that the added semantic to the resources being transfered justify a more explicit Content-Type than just application/json.

Following this reasoning, other contexts could justify a more specific Content-Type.

Imagine that you have:

keys = ('name', 'age', 'food')
values = ('Monty', 42, 'spam')

What is the simplest way to produce the following dictionary ?

dict = {'name' : 'Monty', 'age' : 42, 'food' : 'spam'}

Most performant, dict constructor with zip

new_dict = dict(zip(keys, values))

In Python 3, zip now returns a lazy iterator, and this is now the most performant approach.

dict(zip(keys, values)) does require the one-time global lookup each for dict and zip, but it doesn't form any unnecessary intermediate data-structures or have to deal with local lookups in function application.

Runner-up, dict comprehension:

A close runner-up to using the dict constructor is to use the native syntax of a dict comprehension (not a list comprehension, as others have mistakenly put it):

new_dict = {k: v for k, v in zip(keys, values)}

Choose this when you need to map or filter based on the keys or value.

In Python 2, zip returns a list, to avoid creating an unnecessary list, use izip instead (aliased to zip can reduce code changes when you move to Python 3).

from itertools import izip as zip

So that is still (2.7):

new_dict = {k: v for k, v in zip(keys, values)}

Python 2, ideal for <= 2.6

izip from itertools becomes zip in Python 3. izip is better than zip for Python 2 (because it avoids the unnecessary list creation), and ideal for 2.6 or below:

from itertools import izip
new_dict = dict(izip(keys, values))

Result for all cases:

In all cases:

>>> new_dict
{'age': 42, 'name': 'Monty', 'food': 'spam'}

Explanation:

If we look at the help on dict we see that it takes a variety of forms of arguments:

>>> help(dict)

class dict(object)
 |  dict() -> new empty dictionary
 |  dict(mapping) -> new dictionary initialized from a mapping object's
 |      (key, value) pairs
 |  dict(iterable) -> new dictionary initialized as if via:
 |      d = {}
 |      for k, v in iterable:
 |          d[k] = v
 |  dict(**kwargs) -> new dictionary initialized with the name=value pairs
 |      in the keyword argument list.  For example:  dict(one=1, two=2)

The optimal approach is to use an iterable while avoiding creating unnecessary data structures. In Python 2, zip creates an unnecessary list:

>>> zip(keys, values)
[('name', 'Monty'), ('age', 42), ('food', 'spam')]

In Python 3, the equivalent would be:

>>> list(zip(keys, values))
[('name', 'Monty'), ('age', 42), ('food', 'spam')]

and Python 3's zip merely creates an iterable object:

>>> zip(keys, values)
<zip object at 0x7f0e2ad029c8>

Since we want to avoid creating unnecessary data structures, we usually want to avoid Python 2's zip (since it creates an unnecessary list).

Less performant alternatives:

This is a generator expression being passed to the dict constructor:

generator_expression = ((k, v) for k, v in zip(keys, values))
dict(generator_expression)

or equivalently:

dict((k, v) for k, v in zip(keys, values))

And this is a list comprehension being passed to the dict constructor:

dict([(k, v) for k, v in zip(keys, values)])

In the first two cases, an extra layer of non-operative (thus unnecessary) computation is placed over the zip iterable, and in the case of the list comprehension, an extra list is unnecessarily created. I would expect all of them to be less performant, and certainly not more-so.

Performance review:

In 64 bit Python 3.8.2 provided by Nix, on Ubuntu 16.04, ordered from fastest to slowest:

>>> min(timeit.repeat(lambda: dict(zip(keys, values))))
0.6695233230129816
>>> min(timeit.repeat(lambda: {k: v for k, v in zip(keys, values)}))
0.6941362579818815
>>> min(timeit.repeat(lambda: {keys[i]: values[i] for i in range(len(keys))}))
0.8782548159942962
>>> 
>>> min(timeit.repeat(lambda: dict([(k, v) for k, v in zip(keys, values)])))
1.077607496001292
>>> min(timeit.repeat(lambda: dict((k, v) for k, v in zip(keys, values))))
1.1840861019445583

dict(zip(keys, values)) wins even with small sets of keys and values, but for larger sets, the differences in performance will become greater.

A commenter said:

min seems like a bad way to compare performance. Surely mean and/or max would be much more useful indicators for real usage.

We use min because these algorithms are deterministic. We want to know the performance of the algorithms under the best conditions possible.

If the operating system hangs for any reason, it has nothing to do with what we're trying to compare, so we need to exclude those kinds of results from our analysis.

If we used mean, those kinds of events would skew our results greatly, and if we used max we will only get the most extreme result - the one most likely affected by such an event.

A commenter also says:

In python 3.6.8, using mean values, the dict comprehension is indeed still faster, by about 30% for these small lists. For larger lists (10k random numbers), the dict call is about 10% faster.

I presume we mean dict(zip(... with 10k random numbers. That does sound like a fairly unusual use case. It does makes sense that the most direct calls would dominate in large datasets, and I wouldn't be surprised if OS hangs are dominating given how long it would take to run that test, further skewing your numbers. And if you use mean or max I would consider your results meaningless.

Let's use a more realistic size on our top examples:

import numpy
import timeit
l1 = list(numpy.random.random(100))
l2 = list(numpy.random.random(100))

And we see here that dict(zip(... does indeed run faster for larger datasets by about 20%.

>>> min(timeit.repeat(lambda: {k: v for k, v in zip(l1, l2)}))
9.698965263989521
>>> min(timeit.repeat(lambda: dict(zip(l1, l2))))
7.9965161079890095

A better answer is to leave your script as it was. When doing the Select name, follow it by -ExpandProperty Name like so:

Get-ADGroupMember 'Domain Admins' | Select Name -ExpandProperty Name | out-file Admins.txt

This is a fiddle I always use with my Web applications:

$('body').on('dragstart drop', function(e){
    e.preventDefault();
    return false;
});

It will prevent anything on your app being dragged and dropped. Depending on tour needs, you can replace body selector with any container that childrens should not be dragged.

You can also configure your component like this :

package mypackage;
import org.springframework.context.annotation.Configuration;
   @Configuration
   public class MyConstructorClassConfig {


   @Bean
   public MyConstructorClass myConstructorClass(){
      return new myConstructorClass("foobar");
   }
  }
}

With the Bean annotation, you are telling Spring to register the returned bean in the BeanFactory.

So you can autowire it as you wish.

Works for me, has nothing to do with PHP 5.3. Just like many such options it cannot be overriden via ini_set() when safe_mode is enabled. Check your updated php.ini (and better yet: change the memory_limit there too).
