Floating point numbers are represented in scientific notation as a number of only seven significant digits multiplied by a larger number that represents the place of the decimal place. More information about it on Wikipedia:

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

As per 2018 in App Store Connect. We can delete/remove application with following stats.

App Store Connect details for Remove an app

So, from now onwards we can delete our test applications too from app store connect.

file_exists checks whether a file exist in the specified path or not.

Syntax:

file_exists ( string $filename )

Returns TRUE if the file or directory specified by filename exists; FALSE otherwise.

$filename = BASE_DIR."images/a/test.jpg";
if (file_exists($filename)){
    echo "File exist.";
}else{
    echo "File does not exist.";
}

Another alternative method you can use getimagesize(), it will return 0(zero) if file/directory is not available in the specified path.

if (@getimagesize($filename)) {...}

For Windows 7 x86 you can also download the ISO: http://www.microsoft.com/en-us/download/confirmation.aspx?id=8442

And run \Setup\WinSDKDebuggingTools\dbg_x86.msi

WinDbg.exe will then be installed (default location) to: C:\Program Files (x86)\Debugging Tools for Windows (x86)

No.

Depending on your build environment (you don't specify), you may find that it works in exactly the way that you want.

However, there are many environments (both IDEs and a lot of hand crafted Makefiles) that expect to compile *.c - if that happens you will probably end up with linker errors due to duplicate symbols.

As a rule this practice should be avoided.

If you absolutely must #include source (and generally it should be avoided), use a different file suffix for the file.

public static void getCharacter(String str){

        int count[]= new int[256];

        for(int i=0;i<str.length(); i++){


            count[str.charAt(i)]++;

        }
        System.out.println("The ascii values are:"+ Arrays.toString(count));

        //Now display wht character is repeated how many times

        for (int i = 0; i < count.length; i++) {
            if (count[i] > 0)
               System.out.println("Number of " + (char) i + ": " + count[i]);
        }


    }
}

Write all class/id CSS as below. #applyCSS ID will be parent of all CSS code.

For example you add class .ui-bar-a in CSS for applying to your div:

#applyCSS .ui-bar-a  { font-size:11px; } /* This will be your CSS part */

Below is your HTML part:

<div id="applyCSS">
   <div class="ui-bar-a">testing</div>
</div>

Use Cheerio. It isn't as strict as jsdom and is optimized for scraping. As a bonus, uses the jQuery selectors you already know.

? Familiar syntax: Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.

? Blazingly fast: Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Preliminary end-to-end benchmarks suggest that cheerio is about 8x faster than JSDOM.

? Insanely flexible: Cheerio wraps around @FB55's forgiving htmlparser. Cheerio can parse nearly any HTML or XML document.

You can change the comment character to something besides # like this:

git config --global core.commentchar "@"

Sometimes it's more simple to implement a copy constructor:

public MyObject (MyObject toClone) {
}

It saves you the trouble of handling CloneNotSupportedException, works with final fields and you don't have to worry about the type to return.

The proper function is int fileno(FILE *stream). It can be found in <stdio.h>, and is a POSIX standard but not standard C.

Example of private function

import re
import inspect

class MyClass :

    def __init__(self) :
        pass

    def private_function ( self ) :
        try :
            function_call = inspect.stack()[1][4][0].strip()

            # See if the function_call has "self." in the begining
            matched = re.match( '^self\.', function_call )
            if not matched :
                print 'This is Private Function, Go Away'
                return
        except :
            print 'This is Private Function, Go Away'
            return

        # This is the real Function, only accessible inside class #
        print 'Hey, Welcome in to function'

    def public_function ( self ) :
        # i can call private function from inside the class
        self.private_function()

Heres how I solved it with React and Typescript. Hope it helps !

import * as React from 'react';
import { FC } from 'react';
import { Route, RouteComponentProps, RouteProps, Redirect } from 'react-router';

const PrivateRoute: FC<RouteProps> = ({ component: Component, ...rest }) => {
    if (!Component) {
      return null;
    }
    const isLoggedIn = true; // Add your provider here
    return (
      <Route
        {...rest}
            render={(props: RouteComponentProps<{}>) => isLoggedIn ? (<Component {...props} />) : (<Redirect to={{ pathname: '/', state: { from: props.location } }} />)}
      />
    );
  };

export default PrivateRoute;








<PrivateRoute component={SignIn} path="/signin" />

In order for that to work $time has to be a timestamp. You cannot pass in "10:00" or something like $time = date('H:i', '10:00'); which is what you seem to do, because then I get 0:30 and 1:30 as results too.

Try

$time = strtotime('10:00');

As an alternative, consider using DateTime (the below requires PHP 5.3 though):

$dt = DateTime::createFromFormat('H:i', '10:00'); // create today 10 o'clock
$dt->sub(new DateInterval('PT30M'));              // substract 30 minutes
echo $dt->format('H:i');                          // echo modified time
$dt->add(new DateInterval('PT1H'));               // add 1 hour
echo $dt->format('H:i');                          // echo modified time

or procedural if you don't like OOP

$dateTime = date_create_from_format('H:i', '10:00');
date_sub($dateTime, date_interval_create_from_date_string('30 minutes'));
echo date_format($dateTime, 'H:i');
date_add($dateTime, date_interval_create_from_date_string('1 hour'));
echo date_format($dateTime, 'H:i');

npm install --save bootstrap

afterwards, inside angular.json (previously .angular-cli.json) inside the project's root folder, find styles and add the bootstrap css file like this:

for angular 6

"styles": [
          "../node_modules/bootstrap/dist/css/bootstrap.min.css",
          "styles.css"
],

for angular 7

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
],

You can use names directly in the read_csv

names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None

Cov = pd.read_csv("path/to/file.txt", 
                  sep='\t', 
                  names=["Sequence", "Start", "End", "Coverage"])

Is $target.remove(); what you're looking for?

https://api.jquery.com/remove/

You can directly use hotkey from rich faces if you are using JSF.

<rich:hotKey key="backspace" onkeydown="if (event.keyCode == 8) return false;" handler="return false;" disableInInput="true" />
<rich:hotKey key="f5" onkeydown="if (event.keyCode == 116) return false;" handler="return false;" disableInInput="true" />
<rich:hotKey key="ctrl+R" onkeydown="if (event.keyCode == 123) return false;" handler="return false;" disableInInput="true" />
<rich:hotKey key="ctrl+f5" onkeydown="if (event.keyCode == 154) return false;" handler="return false;" disableInInput="true" /> 

If you are using jQuery, which quite a lot of people do, then you would implement the accepted answer like so:

var canvas = $("#mycanvas")[0];
var img = canvas.toDataURL("image/png");

$("#elememt-to-write-to").html('<img src="'+img+'"/>');

NOTE

willSet and didSet observers are not called when a property is set in an initializer before delegation takes place

getconf works both in Mac OS X and Linux, just in case you need it to be compatible with both systems:

$ getconf _NPROCESSORS_ONLN

I got same problem lot of time. Check your request url, if you are requesting on local server like 127.1.1/api or 192.168...., try to change it, make sure you are hitting cloud.

In 5 years nobody has mentioned .append?

#include <string>

std::string s;
s.append("Hello world, ");
s.append("nice to see you, ");
s.append("or not.");

$str = 15.00;
$str2 = 14.70;
echo rtrim(rtrim(strval($str), "0"), "."); //15
echo rtrim(rtrim(strval($str2), "0"), "."); //14.7

The easiest is to export the variable REQUESTS_CA_BUNDLE that points to your private certificate authority, or a specific certificate bundle. On the command line you can do that as follows:

export REQUESTS_CA_BUNDLE=/path/to/your/certificate.pem
python script.py

If you have your certificate authority and you don't want to type the export each time you can add the REQUESTS_CA_BUNDLE to your ~/.bash_profile as follows:

echo "export REQUESTS_CA_BUNDLE=/path/to/your/certificate.pem" >> ~/.bash_profile ; source ~/.bash_profile

While list(map(int, str(x))) is the Pythonic approach, you can formulate logic to derive digits without any type conversion:

from math import log10

def digitize(x):
    n = int(log10(x))
    for i in range(n, -1, -1):
        factor = 10**i
        k = x // factor
        yield k
        x -= k * factor

res = list(digitize(5243))

[5, 2, 4, 3]

One benefit of a generator is you can feed seamlessly to set, tuple, next, etc, without any additional logic.

If you're using jQuery versions 1.4.3+:

$('selector').click(false);

If not:

$('selector').click(function(){return false;});

Remember, Objective-C is a superset of C, so typecasting works as it does in C:

myEditController = [[SelectionListViewController alloc] init];
((SelectionListViewController *)myEditController).list = listOfItems;

In PostMan we have ->Pre-request Script. Paste the Below snippet.

const dateNow = new Date();
postman.setGlobalVariable("todayDate", dateNow.toLocaleDateString());

And now we are ready to use.

{
"firstName": "SANKAR",
"lastName": "B",
"email": "[email protected]",
"creationDate": "{{todayDate}}"
}

If you are using JPA Entity classes then use the below snippet

    @JsonFormat(pattern="MM/dd/yyyy")
    @Column(name = "creation_date")
    private Date creationDate;

enter image description here enter image description here

<script type="text/javascript">
var jvalue = 'this is javascript value';

<?php $abc = "<script>document.write(jvalue)</script>"?>   
</script>
<?php echo  'php_'.$abc;?>

For Mac Users :

On Mac, head -n -1 wont work. And, I was trying to find a simple solution [ without worrying about processing time ] to solve this problem only using "head" and/or "tail" commands.

I tried the following sequence of commands and was happy that I could solve it just using "tail" command [ with the options available on Mac ]. So, if you are on Mac, and want to use only "tail" to solve this problem, you can use this command :

cat file.txt | tail -r | tail -n +2 | tail -r

Explanation :

1> tail -r : simply reverses the order of lines in its input

2> tail -n +2 : this prints all the lines starting from the second line in its input

There is also the singlespace environment:

\begin{singlespace}
\end{singlespace}

Set the Credentials property before sending the message.

As I understand it a table has a set K of keys and a typing function T with domain K. A row, or "tuple", of the table is a function r with domain K such that r(k) is an element of T(k) for each key k. So the terminology is misleading in that a "tuple" is really more like an associative array.

if (a.y - b.y) is less than (a.x - b.x), m is always zero.

so cast it like this.

float m = ((float)(a.y - b.y)) / ((float)(a.x - b.x));

You can put a "onload" attribute inside the body

...<body onload="myFunction()">...

Or if you are using jQuery, you can do

$(document).ready(function(){ /*code here*/ }) 

or 

$(window).load(function(){ /*code here*/ })

I hope it answer your question.

Note that the $(window).load will execute after the document is rendered on your page.

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"
done

list='"item 1" "item 2" "item 3"'
for i in $list; do
    echo $i
done
for i in "$list"; do
    echo $i
done
for i in ${array[@]}; do
    echo $i
done

None of the above answers helped me. I suppose all the answers are for older OS X

For OS X Yosemite 10.10, follow these steps

Use your favorite text editor to open: ~/.bash_profile

//This command will open the file using vim
$ vim ~/.bash_profile

Add the following line in the file and save it ( : followed by "x" for vim):

export JAVA_HOME=$(/usr/libexec/java_home)

Then in the terminal type the following two commands to see output:

$ source ~/.bash_profile

$ echo $JAVA_HOME

In the second line, you are updating the contents of .bash_profile file.

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

First off, a PetStore is not a farm.

Let's get past this though. You actually don't need access to the private members, you have everything you need in the public interface:

Animal_* getAnimal_(int i);
void addAnimal_(Animal_* newAnimal);

These are the methods you're given access to and these are the ones you should use.

I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ??

Simple, you call addAnimal. It's public and it also increments sizeF.

Also, note that

PetStore()
{
 idF=0;
};

is equivalent to

PetStore() : Farm()
{
 idF=0;
};

i.e. the base constructor is called, base members are initialized.

Definitely use a service to share data between controllers, here is a working example. $broadcast is not the way to go, you should avoid using the eventing system when there is a more appropriate way. Use a 'service', 'value' or 'constant' (for global constants).

http://plnkr.co/edit/ETWU7d0O8Kaz6qpFP5Hp

Here is an example with an input so you can see the data mirror on the page: http://plnkr.co/edit/DbBp60AgfbmGpgvwtnpU

var testModule = angular.module('testmodule', []);

testModule
   .controller('QuestionsStatusController1',
    ['$rootScope', '$scope', 'myservice',
    function ($rootScope, $scope, myservice) {
       $scope.myservice = myservice;   
    }]);

testModule
   .controller('QuestionsStatusController2',
    ['$rootScope', '$scope', 'myservice',
    function ($rootScope, $scope, myservice) {
      $scope.myservice = myservice;
    }]);

testModule
    .service('myservice', function() {
      this.xxx = "yyy";
    });

For directories dirname gets tripped for ../ and returns ./.

nolan6000's function can be modified to fix that:

get_abs_filename() {
  # $1 : relative filename
  if [ -d "${1%/*}" ]; then
    echo "$(cd ${1%/*}; pwd)/${1##*/}"
  fi
}

It took me few hours to solved this because all off the settings that I found here about this error were the same but it still didn't work. The problem was tha I had a folder in my web service from which the file should be send to WinCE device, after converting that folder to an application with Classic.NetAppPool it started to work.

For me, the fix appears to be "git ." (stages all current files). Apparently this is required after a git init? I followed it by "get reset" (unstages all files) and proceeded with the exact same commands to stage only a few files, which then pushed successfully.

   git . 
   git reset

The accepted answer is most likely a red herring. The difference between Django 1.2.4 and 1.2.5 was the requirement for a CSRF token for AJAX requests.

I came across this problem on Django 1.3 and it was caused by the CSRF cookie not being set in the first place. Django will not set the cookie unless it has to. So an exclusively or heavily ajax site running on Django 1.2.4 would potentially never have sent a token to the client and then the upgrade requiring the token would cause the 403 errors.

The ideal fix is here: http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#page-uses-ajax-without-any-html-form
but you'd have to wait for 1.4 unless this is just documentation catching up with the code

Edit

Note also that the later Django docs note a bug in jQuery 1.5 so ensure you are using 1.5.1 or later with the Django suggested code: https://docs.djangoproject.com/en/dev/ref/csrf/#ajax

I had a similar requirement a while back. Its nothing to do with Guava but you can do something like this to be able to cleanly construct a Map using a fluent builder.

Create a base class that extends Map.

public class FluentHashMap<K, V> extends LinkedHashMap<K, V> {
    private static final long serialVersionUID = 4857340227048063855L;

    public FluentHashMap() {}

    public FluentHashMap<K, V> delete(Object key) {
        this.remove(key);
        return this;
    }
}

Then create the fluent builder with methods that suit your needs:

public class ValueMap extends FluentHashMap<String, Object> {
    private static final long serialVersionUID = 1L;

    public ValueMap() {}

    public ValueMap withValue(String key, String val) {
        super.put(key, val);
        return this;
    }

... Add withXYZ to suit...

}

You can then implement it like this:

ValueMap map = new ValueMap()
      .withValue("key 1", "value 1")
      .withValue("key 2", "value 2")
      .withValue("key 3", "value 3")

using System.Linq;    
list.Where(x=> x.Name == nameToExtract);

Edit: misread question (now all matches)

Only solution that worked for me

$ sudo killall -u username && sudo deluser --remove-home -f username

The killall command is used if multiple processes are used by the user you want to delete.

The -f option forces the removal of the user account, even if the user is still logged in. It also forces deluser to remove the user's home directory and mail spool, even if another user uses the same home directory.

Please confirm that it works in the comments.

Note also that if you have wordpress just scroll down to the bottom of the webpage when in edit mode, and select "featured image" (bottom right side of screen).

UPDATE:

New link for the icons image size by apple.

https://developer.apple.com/ios/human-interface-guidelines/graphics/image-size-and-resolution/

Yes it's True here it is Apple provide Official documentation regarding icon's or image size

you have to set images for iPhone6 and iPhone6+

For iPhone 6:

750 x 1334 (@2x) for portrait

1334 x 750 (@2x) for landscape

For iPhone 6 Plus:

1242 x 2208 (@3x) for portrait

2208 x 1242 (@3x) for landscape

For more info regarding Images and it's resolution this is best ever helpful post

For setting images size for controls you can set 1x @2x and @3x like following:

My naive assumption was that the size of scroll pane will be determined automatically...

The only solution that actually worked for me was explicitly seeting bounds of JScrollPane:

import javax.swing.*;

public class MyFrame extends JFrame {

    public MyFrame()
    {
        setBounds(100, 100, 491, 310);
        getContentPane().setLayout(null);

        JTextArea textField = new JTextArea();
        textField.setEditable(false);

        String str = "";
        for (int i = 0; i < 50; ++i)
            str += "Some text\n";
        textField.setText(str);

        JScrollPane scroll = new JScrollPane(textField);
        scroll.setBounds(10, 11, 455, 249);                     // <-- THIS

        getContentPane().add(scroll);
        setLocationRelativeTo ( null );
    }
}

Maybe it will help some future visitors :)

An easier way of doing the same:

Type cast integer to character, let int n be the integer, then:

Char c=(char)n;
System.out.print(c)//char c will store the converted value.

You can make a static property that initializes and returns a default "rational" number:

public static Rational One => new Rational(0, 1); 

And use it like:

var rat = Rational.One;

Though there are so many good answers, here is my two cents for the future me :P and for anyone who wants it quick and easy.

For Mac:

• connect the device using USB first and make sure debugging is working. Disconnect any other devices and quit emulators.

• open terminal and run the following script

  adb tcpip 5555
  adb connect $(adb shell ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | cut -d: -f2):5555
  

• disconnect USB connection and the device should be available for WiFi debugging

Explanation:

adb tcpip 5555 commands the device to start listening for connections on port 5555

adb connect $(_ip_address_fetched_):5555 tells to connect on port 5555 of the _ip_address_fetched_ address

where _ip_address_fetched_ includes following:

adb shell ifconfig getting internet configurations using adb shell

grep "inter " filter any line that starts with inter

grep -v 127.0.0.1 exclude localhost.

At this point, output should be like:

inet addr:###.###.#.### Bcast:###.###.#.### Mask:255.255.255.0

awk '{print $2}' get the second part of the components array, separated by space (I'm using zsh).

The output up to this point is

addr:###.###.#.###

cut -d: -f2 split the string by delimiter : and take second part. It will only take your device IP address

If you just want to suppress warnings from a function, you can add an @ sign in front:

<?php @function_that_i_dont_want_to_see_errors_from(parameters); ?>

If you want a TRIE implemented as a Python class, here is something I wrote after reading about them:

class Trie:

    def __init__(self):
        self.__final = False
        self.__nodes = {}

    def __repr__(self):
        return 'Trie<len={}, final={}>'.format(len(self), self.__final)

    def __getstate__(self):
        return self.__final, self.__nodes

    def __setstate__(self, state):
        self.__final, self.__nodes = state

    def __len__(self):
        return len(self.__nodes)

    def __bool__(self):
        return self.__final

    def __contains__(self, array):
        try:
            return self[array]
        except KeyError:
            return False

    def __iter__(self):
        yield self
        for node in self.__nodes.values():
            yield from node

    def __getitem__(self, array):
        return self.__get(array, False)

    def create(self, array):
        self.__get(array, True).__final = True

    def read(self):
        yield from self.__read([])

    def update(self, array):
        self[array].__final = True

    def delete(self, array):
        self[array].__final = False

    def prune(self):
        for key, value in tuple(self.__nodes.items()):
            if not value.prune():
                del self.__nodes[key]
        if not len(self):
            self.delete([])
        return self

    def __get(self, array, create):
        if array:
            head, *tail = array
            if create and head not in self.__nodes:
                self.__nodes[head] = Trie()
            return self.__nodes[head].__get(tail, create)
        return self

    def __read(self, name):
        if self.__final:
            yield name
        for key, value in self.__nodes.items():

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

you have to create a instance of the class for calling the method..

Why are there extra spaces between my month and day? Why does't it just put them next to each other?

So your output will be aligned.

If you don't want padding use the format modifier FM:

SELECT TO_CHAR (date_field, 'fmMonth DD, YYYY') 
  FROM ...;

If you've changed the search_path, specify the public schema in the function call:

Sorry I know this is old but why not style all tr elements the way you want all except the first and the use the psuedo class :first-child where you revoke what you specified for all tr elements.

Better descriped by this example:

You can use this awesome library to compress. Add dependency in app-level gradel:

    dependencies {
    implementation 'id.zelory:compressor:3.0.0'
}

And then just compress the actual image file like this:

val compressedImageFile = Compressor.compress(context, actualImageFile)

select T1.name, count (*)
from (select name from Results 
      union 
      select name from Archive_Results) as T1
group by T1.name order by T1.name

The R class is Java code auto-generated from your XML files (UI layout, internationalization strings, etc.) If the code used to be working before (as it seems it is), you need to tell your IDE to regenerate these files somehow:

• in IntelliJ, select Tools > Android > Generate sources for <project>
• (If you know the way in another IDE, feel free to edit this answer!)

There is also a built-in function for this task:

variable = lines( itab_name ).

Just like the "pure" ABAP syntax described by IronGoofy, the function "lines( )" writes the number of lines of table itab_name into the variable.

Uninstall(delete) this: jre, jdk, eclipse. Download 32 bit(x86) version of this programs:jre, jdk, eclipse. And install it.

Best way of doing it

Below code is to copy the visible data in DBExtract sheet, and paste it into duplicateRecords sheet, with only filtered values. Range selected by me is the maximum range that can be occupied by my data. You can change it as per your need.

  Sub selectVisibleRange()

    Dim DbExtract, DuplicateRecords As Worksheet
    Set DbExtract = ThisWorkbook.Sheets("Export Worksheet")
    Set DuplicateRecords = ThisWorkbook.Sheets("DuplicateRecords")

    DbExtract.Range("A1:BF9999").SpecialCells(xlCellTypeVisible).Copy
    DuplicateRecords.Cells(1, 1).PasteSpecial


    End Sub

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

If you are trying to simply return a string to a View, try this:

public string Test()
{
     return "test";
}

This will return a view with the word test in it. You can insert some html in the string.

You can also try this:

public ActionResult Index()
{
    return Content("<html><b>test</b></html>");
}

Just a reminder of a mistake I made myself too, the

 __block

declaration must be done when first declaring the variable, that is, OUTSIDE of the block, not inside of it. This should resolve problems mentioned in the comments about the variable not retaining its value outside of the block.

I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)

The screen you show is DateTimeSettings. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time"; and also to Settings.System.AUTO_TIME

This settings is observed by an observed called mAutoTimeObserver in the 2 network ServiceStateTrackers: GsmServiceStateTracker and CdmaServiceStateTracker.

Both implementations call a method called revertToNitz() when the settings becomes true. Apparently NITZ is the equivalent of NTP in the carrier world.

Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz(). Unfortunately, I haven't found a mechanism to get the network time. If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTrackers implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime.

here is a very mechanical method without the distracting theories:

1. Convert the number into binary representation (use a calculator ok?)
2. Only copy the rightmost 8 bits (LSB) and discard the rest.
3. From the result of step#2, if the leftmost bit is 0, then use a calculator to convert the number to decimal. This is your answer.
4. Else (if the leftmost bit is 1) your answer is negative. Leave all rightmost zeros and the first non-zero bit unchanged. And reversed the rest, that is, replace 1's by 0's and 0's by 1's. Then use a calculator to convert to decimal and append a negative sign to indicate the value is negative.

This more practical method is in accordance to the much theoretical answers above. So, those still reading those Java books saying to use modulo, this is definitely wrong since the 4 steps I outlined above is definitely not a modulo operation.

Numpy matrices are strictly 2-dimensional, while numpy arrays (ndarrays) are N-dimensional. Matrix objects are a subclass of ndarray, so they inherit all the attributes and methods of ndarrays.

The main advantage of numpy matrices is that they provide a convenient notation for matrix multiplication: if a and b are matrices, then a*b is their matrix product.

import numpy as np

a = np.mat('4 3; 2 1')
b = np.mat('1 2; 3 4')
print(a)
# [[4 3]
#  [2 1]]
print(b)
# [[1 2]
#  [3 4]]
print(a*b)
# [[13 20]
#  [ 5  8]]

On the other hand, as of Python 3.5, NumPy supports infix matrix multiplication using the @ operator, so you can achieve the same convenience of matrix multiplication with ndarrays in Python >= 3.5.

import numpy as np

a = np.array([[4, 3], [2, 1]])
b = np.array([[1, 2], [3, 4]])
print(a@b)
# [[13 20]
#  [ 5  8]]

Both matrix objects and ndarrays have .T to return the transpose, but matrix objects also have .H for the conjugate transpose, and .I for the inverse.

In contrast, numpy arrays consistently abide by the rule that operations are applied element-wise (except for the new @ operator). Thus, if a and b are numpy arrays, then a*b is the array formed by multiplying the components element-wise:

c = np.array([[4, 3], [2, 1]])
d = np.array([[1, 2], [3, 4]])
print(c*d)
# [[4 6]
#  [6 4]]

To obtain the result of matrix multiplication, you use np.dot (or @ in Python >= 3.5, as shown above):

print(np.dot(c,d))
# [[13 20]
#  [ 5  8]]

The ** operator also behaves differently:

print(a**2)
# [[22 15]
#  [10  7]]
print(c**2)
# [[16  9]
#  [ 4  1]]

Since a is a matrix, a**2 returns the matrix product a*a. Since c is an ndarray, c**2 returns an ndarray with each component squared element-wise.

There are other technical differences between matrix objects and ndarrays (having to do with np.ravel, item selection and sequence behavior).

The main advantage of numpy arrays is that they are more general than 2-dimensional matrices. What happens when you want a 3-dimensional array? Then you have to use an ndarray, not a matrix object. Thus, learning to use matrix objects is more work -- you have to learn matrix object operations, and ndarray operations.

Writing a program that mixes both matrices and arrays makes your life difficult because you have to keep track of what type of object your variables are, lest multiplication return something you don't expect.

In contrast, if you stick solely with ndarrays, then you can do everything matrix objects can do, and more, except with slightly different functions/notation.

If you are willing to give up the visual appeal of NumPy matrix product notation (which can be achieved almost as elegantly with ndarrays in Python >= 3.5), then I think NumPy arrays are definitely the way to go.

PS. Of course, you really don't have to choose one at the expense of the other, since np.asmatrix and np.asarray allow you to convert one to the other (as long as the array is 2-dimensional).

There is a synopsis of the differences between NumPy arrays vs NumPy matrixes here.

Another alternative is the following, although not the cleanest as it assumes the image to be the only element in a container, such as in this case:

<header class="siteHeader">
  <img src="img" class="siteLogo" />
</header>

You can then use the container as a mask with the desired size, and surround the image with a negative margin to move it into the right position:

.siteHeader{
    width: 50px;
    height: 50px;
    overflow: hidden;
}

.siteHeader .siteLogo{
    margin: -100px;
}

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)

What worked for me, using jQuery and tested in IE8, Chrome and Firefox, is:

$(window).bind("beforeunload",function(event) {
    if(hasChanged) return "You have unsaved changes";
});

It is important not to return anything if no prompt is required as there are differences between IE and other browser behaviours here.

Culprit (in my case):
A high-latency network.

This is not an answer per se but more of an observation that may help others. I found that this error pops up occasionally on high-latency networks (I have to use a Satellite dish for internet access for example). The speed of the network is fine, but the latency can be high. Note: The problem only exists in certain scenarios, but I have not determined what the pattern is.

Temporary mitigation:
I switched networks—I moved to a slower, but lower latency cell network (my phone used as a hotspot)—and the problem disappeared. Note that I can only do this itermittently because my cell connectivity is also intermittent. Plus the bandwidth usage adds costs. I'm also lucky that I have this option available to me. Not everyone does.

I'm sure there is some configuration setting somewhere that makes git—or ssh or curl or whatever times out first—more tolerant of such networks, but I don't know what it is.

A plea to developers:
These kinds of issues are a constant problem for rural populations. Please think of us when you design your systems, tools, and applications. Thank you.

In my app I created a WidgetChooser widget so I can choose between widgets without conditional logic:

WidgetChooser(
      condition: true,
      trueChild: Text('This widget appears if the condition is true.'),
      falseChild: Text('This widget appears if the condition is false.'),
    );

This is the source for the WidgetChooser widget:

import 'package:flutter/widgets.dart';

class WidgetChooser extends StatelessWidget {
  final bool condition;
  final Widget trueChild;
  final Widget falseChild;

  WidgetChooser({@required this.condition, @required this.trueChild, @required this.falseChild});

  @override
  Widget build(BuildContext context) {
    if (condition) {
      return trueChild;
    } else {
      return falseChild;
    }
  }
}

To correctly save the instance state of Fragment you should do the following:

1. In the fragment, save instance state by overriding onSaveInstanceState() and restore in onActivityCreated():

class MyFragment extends Fragment {

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's state here
        }
    }
    ...
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's state here
    }

}

2. And important point, in the activity, you have to save the fragment's instance in onSaveInstanceState() and restore in onCreate().

class MyActivity extends Activity {

    private MyFragment 

    public void onCreate(Bundle savedInstanceState) {
        ...
        if (savedInstanceState != null) {
            //Restore the fragment's instance
            mMyFragment = getSupportFragmentManager().getFragment(savedInstanceState, "myFragmentName");
            ...
        }
        ...
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        //Save the fragment's instance
        getSupportFragmentManager().putFragment(outState, "myFragmentName", mMyFragment);
    }

}

Hope this helps.

You can also use jQuery's delay() method instead of setTimeout(). It'll give you much more readable code. Here's an example from the docs:

$( "#foo" ).slideUp( 300 ).delay( 800 ).fadeIn( 400 );

The only limitation (that I'm aware of) is that it doesn't give you a way to clear the timeout. If you need to do that then you're better off sticking with all the nested callbacks that setTimeout thrusts upon you.

SELECT a.image_id 
FROM list a
INNER JOIN list b
   ON a.image_id = b.image_id
   AND b.style_id = 25
   AND b.style_value = 'big'
INNER JOIN list c
   ON a.image_id = c.image_id
   AND c.style_id = 27
   AND c.style_value = 'round'
WHERE a.style_id = 24 
   AND a.style_value = 'red'

I'm not sure but I commonly initialize an array to "" in that case I don't need worry about the null end of the string.

main() {
    void something(char[]);
    char s[100] = "";

    something(s);
    printf("%s", s);
}

void something(char s[]) {
    // ... do something, pass the output to s
    // no need to add s[i] = '\0'; because all unused slot is already set to '\0'
}

As offer_date is an number, and is of lower accuracy than your real dates, this may work...
- Convert your real date to a string of format YYYYMM
- Conver that value to an INT
- Compare the result you your offer_date

SELECT
  *
FROM
  offers
WHERE
    offer_date = (SELECT CAST(to_char(create_date, 'YYYYMM') AS INT) FROM customers where id = '12345678')
AND offer_rate > 0 

Also, by doing all the manipulation on the create_date you only do the processing on one value.

Additionally, had you manipulated the offer_date you would not be able to utilise any index on that field, and so force SCANs instead of SEEKs.

You can use Google Guava Table

Based on your question:

My question is, using the code below, how would you be able to have multiple clients connected? I've tried lists, but I just can't figure out the format for that. How can this be accomplished where multiple clients are connected at once and I am able to send a message to a specific client?

Using the code you gave, you can do this:

#!/usr/bin/python           # This is server.py file                                                                                                                                                                           

import socket               # Import socket module
import thread

def on_new_client(clientsocket,addr):
    while True:
        msg = clientsocket.recv(1024)
        #do some checks and if msg == someWeirdSignal: break:
        print addr, ' >> ', msg
        msg = raw_input('SERVER >> ')
        #Maybe some code to compute the last digit of PI, play game or anything else can go here and when you are done.
        clientsocket.send(msg)
    clientsocket.close()

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 50000                # Reserve a port for your service.

print 'Server started!'
print 'Waiting for clients...'

s.bind((host, port))        # Bind to the port
s.listen(5)                 # Now wait for client connection.

print 'Got connection from', addr
while True:
   c, addr = s.accept()     # Establish connection with client.
   thread.start_new_thread(on_new_client,(c,addr))
   #Note it's (addr,) not (addr) because second parameter is a tuple
   #Edit: (c,addr)
   #that's how you pass arguments to functions when creating new threads using thread module.
s.close()

As Eli Bendersky mentioned, you can use processes instead of threads, you can also check python threading module or other async sockets framework. Note: checks are left for you to implement how you want and this is just a basic framework.

 @Override
    public void onResume() {

        super.onResume();

        getView().setFocusableInTouchMode(true);
        getView().requestFocus();
        getView().setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {

                if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){

                    if (mDrawerLayout.isDrawerOpen(GravityCompat.START)){
                        mDrawerLayout.closeDrawer(GravityCompat.START);
                    }
                    return true;
                }

                return false;
            }
        });
    }

The error seems clear: model objects do not support item assignment. MyModel.objects.latest('id')['foo'] = 'bar' will throw this same error.

It's a little confusing that your model instance is called projectForm...

To reproduce your first block of code in a loop, you need to use setattr

for k,v in session_results.iteritems():
    setattr(projectForm, k, v)

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

Try this:

myfile %>% mutate(V5 = (V1 == 1 & V2 != 4) + 2 * (V2 == 4 & V3 != 1))

giving:

  V1 V2 V3 V4 V5
1  1  2  3  5  1
2  2  4  4  1  2
3  1  4  1  1  0
4  4  5  1  3  0
5  5  5  5  4  0

or this:

myfile %>% mutate(V5 = ifelse(V1 == 1 & V2 != 4, 1, ifelse(V2 == 4 & V3 != 1, 2, 0)))

giving:

  V1 V2 V3 V4 V5
1  1  2  3  5  1
2  2  4  4  1  2
3  1  4  1  1  0
4  4  5  1  3  0
5  5  5  5  4  0

Note

Suggest you get a better name for your data frame. myfile makes it seem as if it holds a file name.

Above used this input:

myfile <- 
structure(list(V1 = c(1L, 2L, 1L, 4L, 5L), V2 = c(2L, 4L, 4L, 
5L, 5L), V3 = c(3L, 4L, 1L, 1L, 5L), V4 = c(5L, 1L, 1L, 3L, 4L
)), .Names = c("V1", "V2", "V3", "V4"), class = "data.frame", row.names = c("1", 
"2", "3", "4", "5"))

Update 1 Since originally posted dplyr has changed %.% to %>% so have modified answer accordingly.

Update 2 dplyr now has case_when which provides another solution:

myfile %>% 
       mutate(V5 = case_when(V1 == 1 & V2 != 4 ~ 1, 
                             V2 == 4 & V3 != 1 ~ 2,
                             TRUE ~ 0))

You could use the TIMEDIFF() and the TIME_TO_SEC() functions as follows:

SELECT TIME_TO_SEC(TIMEDIFF('2010-08-20 12:01:00', '2010-08-20 12:00:00')) diff;
+------+
| diff |
+------+
|   60 |
+------+
1 row in set (0.00 sec)

You could also use the UNIX_TIMESTAMP() function as @Amber suggested in an other answer:

SELECT UNIX_TIMESTAMP('2010-08-20 12:01:00') - 
       UNIX_TIMESTAMP('2010-08-20 12:00:00') diff;
+------+
| diff |
+------+
|   60 |
+------+
1 row in set (0.00 sec)

If you are using the TIMESTAMP data type, I guess that the UNIX_TIMESTAMP() solution would be slightly faster, since TIMESTAMP values are already stored as an integer representing the number of seconds since the epoch (Source). Quoting the docs:

When UNIX_TIMESTAMP() is used on a TIMESTAMP column, the function returns the internal timestamp value directly, with no implicit “string-to-Unix-timestamp” conversion.

Keep in mind that TIMEDIFF() return data type of TIME. TIME values may range from '-838:59:59' to '838:59:59' (roughly 34.96 days)

It is possible in VSS by three ways.

1. You can click on Active sync icon on Solution Explorer.

2. By selecting Active sync checkbox in Tools (Tools > Options > Projects and Solutions > General). In that check the Track Active Item in Solution Explorer Checkbox. When you select a file in the main window, it will automatically navigate to active file in the Explorer.

3. By using the Shortcut key (Ctrl + [ + S), you can able to navigate to active Item.

Note: Either 1 or 2 only works in a mean time.. So You have to use either 1st or 2nd.

in ts, [].push(bufferPart) is not compatible;

so:

getBufferFromStream(stream: Part | null): Promise<Buffer> {
    if (!stream) {
        throw 'FILE_STREAM_EMPTY';
    }
    return new Promise(
        (r, j) => {
            let buffer = Buffer.from([]);
            stream.on('data', buf => {
               buffer = Buffer.concat([buffer, buf]);
            });
            stream.on('end', () => r(buffer));
            stream.on('error', j);
        }
    );
}

CMake (Cross platform make) is a build system generator. It doesn't build your source, instead, generates what a build system needs: the build scripts. Doing so you don't need to write or maintain platform specific build files. CMake uses relatively high level CMake language which usually written in CMakeLists.txt files. Your general workflow when consuming third party libraries usually boils down the following commands:

cmake -S thelibrary -B build
cmake --build build
cmake --install build

The first line known as configuration step, this generates the build files on your system. -S(ource) is the library source, and -B(uild) folder. CMake falls back to generate build according to your system. it will be MSBuild on Windows, GNU Makefiles on Linux. You can specify the build using -G(enerator) paramater, like:

cmake -G Ninja -S libSource -B build

end of the this step, generates build scripts, like Makefile, *.sln files etc. on build directory.

The second line invokes the actual build command, it's like invoking make on the build folder.

The third line install the library. If you're on Windows, you can quickly open generated project by, cmake --open build.

Now you can use the installed library on your project with configured by CMake, writing your own CMakeLists.txt file. To do so, you'll need to create a your target and find the package you installed using find_package command, which will export the library target names, and link them against your own target.

There is an alternative command where you can get the raw value of a cell where formula is put on. It's returns type is String. Use:

cell.getRawValue();

An answer taken from ChristopheD here: https://stackoverflow.com/a/2500023/1225603

r = "456results string789"
s = ''.join(x for x in r if x.isdigit())
print int(s)
456789

As @Agam said,

You need this statement in your driver file: from AthleteList import AtheleteList

Change the file extension of your css file to .less. You don't need to write any LESS in it; all CSS is valid LESS (except of the MS stuff that you have to escape, but that's another issue.)

Per Fractalf's answer this is fixed in v1.4.0

PHP_EOL returns a string corresponding to the line break on the platform(LF, \n ou #10 sur Unix, CRLF, \n\r ou #13#10 sur Windows).

echo "Hello World".PHP_EOL;

If you want to open specific activity of another application we can use this.

Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.fuelgauge.PowerUsageSummary");
intent.setComponent(cn);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try 
{
    startActivity(intent)
}catch(ActivityNotFoundException e){
    Toast.makeText(context,"Activity Not Found",Toast.LENGTH_SHORT).show()
}

If you must need other application, instead of showing Toast you can show a dialog. Using dialog you can bring the user to Play-Store to download required application.

I'm familiar with this problem. The simplest workaround is to conditionally repeat the operation. I've never seen it fail twice in a row - unless there actually is an open file or a permissions issue, obviously!

rd /s /q c:\deleteme
if exist c:\deleteme rd /s /q c:\deleteme

Working with Angular 7 I needed to create a file upload with a description of the file.

HTML:

<div>
File Description: <input type="text" (change)="updateFileDescription($event.target.value)" #fileDescription />
</div>

<div>
<input type="file" accept="*" capture (change)="handleFileInput($event.target.files)" #fileInput /> <button class="btn btn-light" (click)="uploadFileToActivity()">Upload</button>
</div>

Here is the Component file

  @ViewChild('fileDescription') fileDescriptionInput: ElementRef;
  @ViewChild('fileInput') fileInput: ElementRef;

ClearInputs(){
        this.fileDescriptionInput.nativeElement.value = '';
        this.fileInput.nativeElement.value = '';
}

This will do the trick.

You'd need to use JavaScript to accomplish this, I think.

jQuery:

$(function(){
   $("#innerContainer").hover(
        function(){
            $("#innerContainer").css('border-color','#FFF');
            $("#outerContainer").css('border-color','#FFF');
        },
        function(){
            $("#innerContainer").css('border-color','#000');
            $("#outerContainer").css('border-color','#000');
        }
    );
});

Adjust the values and element id's accordingly :)

If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.

The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.

.required label {
    font-weight: bold;
}
.required label:after {
    color: #e32;
    content: ' *';
    display:inline;
}

Fiddle with your exact structure: http://jsfiddle.net/bQ859/

sample code is here ,its very easy

LayoutParams params1 = (LayoutParams)twoLetter.getLayoutParams();//twoletter-imageview
                params1.height = 70;
                params1.setMargins(0, 210, 0, 0);//top margin -210 here
                twoLetter.setLayoutParams(params1);//setting layout params
                twoLetter.setImageResource(R.drawable.oo);

If you want to permit an array of hashes(or an array of objects from the perspective of JSON)

params.permit(:foo, array: [:key1, :key2])

2 points to notice here:

1. array should be the last argument of the permit method.
2. you should specify keys of the hash in the array, otherwise you will get an error Unpermitted parameter: array, which is very difficult to debug in this case.

Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80 (there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80. Make sure that View ? Word Wrap is selected.

To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User and use any of the following rules:

{
    // set vertical rulers in specified columns.
    // Use "rulers": [80] for just one ruler
    // default value is []
    "rulers": [80, 100, 120],

    // turn on word wrap for source and text
    // default value is "auto", which means off for source and on for text
    "word_wrap": true,

    // set word wrapping at this column
    // default value is 0, meaning wrapping occurs at window width
    "wrap_width": 80
}

These settings can also be used in a .sublime-project file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings file if you only want them to apply to files written in a certain language (Python.sublime-settings vs. JavaScript.sublime-settings, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User.

As always, if you have multiple entries in your settings file, separate them with commas , except for after the last one. The entire content should be enclosed in curly braces { }. Basically, make sure it's valid JSON.

If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.

Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0 and O (digit zero and capital letter oh) and 1 and l (digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).

The simple solution that worked for me as below, wrap the table with a div and change the line-height, this line-height is taken as a ratio.

<div class="col-md-6" style="line-height: 0.5">_x000D_
                                <table class="table table-striped" >_x000D_
                                    <thead>_x000D_
                                    <tr>_x000D_
                                        <th>Parameter</th>_x000D_
                                        <th>Recorded Value</th>_x000D_
                                        <th>Individual Score</th>_x000D_
                                    </tr>_x000D_
                                    </thead>_x000D_
                                    <tbody>_x000D_
                                    <tr>_x000D_
                                        <td>Respiratory Rate</td>_x000D_
                                        <td>Doe</td>_x000D_

                                    </tr>_x000D_
                                    <tr>_x000D_
                                        <td>Respiratory Effort</td>_x000D_
                                        <td>Moe</td>_x000D_
                                        <td>[email protected]</td>_x000D_
                                    </tr>_x000D_
                                    <tr>_x000D_
                                        <td>Oxygon Saturation</td>_x000D_
                                        <td>Dooley</td>_x000D_
                                        <td>[email protected]</td>_x000D_
                                    </tr>_x000D_
                                    </tbody>_x000D_
                                </table>_x000D_
                            </div>

Try changing the value as it fits for you.

String.prototype.encodeHex = function () {
    return this.split('').map(e => e.charCodeAt())
};

String.prototype.decodeHex = function () {

If your code looks good, verify that jQuery successfully loaded to your server. In my case, the jQuery files were published to the server by my IDE, but the web server only had a 0 KB file stub. With no content, the server failed to serve the file to the browser.

After re-publishing the file and verifying that the server actually received the whole file, then my web page stopped giving me the error.

If you are working RESTfully, GET should be used for requests where you are only getting data, and POST should be used for requests where you are making something happen.

Some examples:

• GET the page showing a particular SO question

• POST a comment

• Send a POST request by clicking the "Add to cart" button.

You can use the keyword IDENTITY as the data type to the column along with PRIMARY KEY constraint when creating the table.
ex:

StudentNumber IDENTITY(1,1) PRIMARY KEY

In here the first '1' means the starting value and the second '1' is the incrementing value.

  is the numeric reference for the entity reference   — they are the exact same thing. It's likely your editor is simply inserting the numberic reference instead of the named one.

See the Wikipedia page for the non-breaking space.

for (int i = 0; i < list.length; i++) {
   if (list.get(i) .getName().equalsIgnoreCase("myName")) {
    System.out.println(i);
    break;
  }
}

How about Properties files in your choice of encodings? Used to be, when you loaded your Properties, you provided an InputStream and the load() method decoded it as ISO-8859-1. You could actually store the file in some other encoding, but you had to use a disgusting hack like this after loading to properly decode the data:

String realProp = new String(prop.getBytes("ISO-8859-1"), "UTF-8");

But, as of JDK 1.6, there's a load() method that takes a Reader instead of an InputStream, which means you can use the correct encoding from the beginning (there's also a store() method that takes a Writer). This seems like a pretty big deal to me, but it appears to have been snuck into the JDK with no fanfare at all. I only stumbled upon it a few weeks ago, and a quick Google search turned up just one passing mention of it.

Try the following:

document.getElementById("successAndErrorMessages").innerHTML="someContent";

It's maybe better to state this difference by the Mutability / Immutability notion that is the correct paradigm of values and instances changeability in Objects space which is larger than the only "constant / variable" usual notions. And furthermore this is closer to Objective C approach.

2 data types: value type and reference type.

In the context of Value Types:

'let' defines a constant value (immutable). 'var' defines a changeable value (mutable).

let aInt = 1   //< aInt is not changeable

var aInt = 1   //< aInt can be changed

In the context of Reference Types:

The label of a data is not the value but the reference to a value.

if aPerson = Person(name:Foo, first:Bar)

aPerson doesn't contain the Data of this person but the reference to the data of this Person.

let aPerson = Person(name:Foo, first:Bar)
               //< data of aPerson are changeable, not the reference

var aPerson = Person(name:Foo, first:Bar)
               //< both reference and data are changeable.

eg:

var aPersonA = Person(name:A, first: a)
var aPersonB = Person(name:B, first: b)

aPersonA = aPersonB

aPersonA now refers to Person(name:B, first: b)

and

let aPersonA = Person(name:A, first: a)
let aPersonB = Person(name:B, first: b)

let aPersonA = aPersonB // won't compile

but

let aPersonA = Person(name:A, first: a)

aPersonA.name = "B" // will compile

This worked for me:

step 1) Removing the interpreter, auto configuring it again

step 2) Window - Preferences - PyDev - Interpreters - Python Interpreter Go to the Forced builtins tab Click on New... Type the name of the module (curses in my case) and click OK

step 3) Right click in the project explorer on whichever module is giving errors. Go to PyDev->Code analysis.

In distributable software, I dont want my customers mucking about in the database by themselves. The program reads and writes it all by itself. The only reason for a user to touch the DB file is to take a backup copy. Therefore I have named it whatever_records.db

The simple .db extension tells the user that it is a binary data file and that's all they have to know. Calling it .sqlite invites the interested user to open it up and mess something up!

Totally depends on your usage scenario I suppose.

Rendering didn't work for me too. I had <null> value on the right side of the android icon. I ran

sudo apt-get install gradle

I restarted Android studio then and <null> value changed to 23.

Voila, it renders now! :)

Once you have the source trees, e.g.

diff -ENwbur repos1/ repos2/ 

Even better

diff -ENwbur repos1/ repos2/  | kompare -o -

and have a crack at it in a good gui tool :)

• -Ewb ignore the bulk of whitespace changes
• -N detect new files
• -u unified
• -r recurse

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

one quick addendum regarding: usually you put those forward references into a header file belonging to the .c(pp) file where the function/variable etc. is implemented. in your example it would look like this: add.h:

extern int add(int a, int b);

the keyword extern states that the function is actually declared in an external file (could also be a library etc.). your main.c would look like this:

#include 
#include "add.h"

int main()
{
.
.
.

After years, I want to add another approach by using a view engine in Express.js

var fs = require('fs');

app.get('/test', function(req, res, next) {
    var html = fs.readFileSync('./html/test.html', 'utf8')
    res.render('test', { html: html })
    // or res.send(html)
})

Then, do that in your views/test if you choose res.render method at the above code (I'm writing in EJS format):

<%- locals.html %>

That's all.

In this way, you don't need to break your View Engine arrangements.

From what you printed, it seems var2 is an array containing one string. Or actually, it appears to hold the result of running .inspect on an array containing one string. It would be helpful to show how you are initializing them.

irb(main):005:0* v1 = "test"
=> "test"
irb(main):006:0> v2 = ["test"]
=> ["test"]
irb(main):007:0> v3 = v2.inspect
=> "[\"test\"]"
irb(main):008:0> puts v1,v2,v3
test
test
["test"]

Try this:

using System;
using Newtonsoft.Json;
using System.Collections.Generic;
public class Program
{
    public static void Main()
    {
        List<Man> Men = new List<Man>();

        Man m1 = new Man();
        m1.Number = "+1-9169168158";
        m1.Message = "Hello Bob from 1";
        m1.UniqueCode = "0123";
        m1.State = 0;

        Man m2 = new Man();
        m2.Number = "+1-9296146182";
        m2.Message = "Hello Bob from 2";
        m2.UniqueCode = "0125";
        m2.State = 0;

        Men.AddRange(new Man[] { m1, m2 });

        string result = JsonConvert.SerializeObject(Men);
        Console.WriteLine(result);  

        List<Man> NewMen = JsonConvert.DeserializeObject<List<Man>>(result);
        foreach(Man m in NewMen) Console.WriteLine(m.Message);
    }
}
public class Man
{
    public string Number{get;set;}
    public string Message {get;set;}
    public string UniqueCode {get;set;}
    public int State {get;set;}
}

I was wondering nobody suggested to create own extension method more readable name for OP's case.

public static bool IsNullOrEmpty<T>(this IEnumerable<T> source)
{
    if (source == null)
    {
        return true;
    }

    return source.Any() == false;
}

In C, the type specifier keywords of structures, unions and enumerations are mandatory, ie you always have to prefix the type's name (its tag) with struct, union or enum when referring to the type.

You can get rid of the keywords by using a typedef, which is a form of information hiding as the actual type of an object will no longer be visible when declaring it.

It is therefore recommended (see eg the Linux kernel coding style guide, Chapter 5) to only do this when you actually want to hide this information and not just to save a few keystrokes.

An example of when you should use a typedef would be an opaque type which is only ever used with corresponding accessor functions/macros.

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

PostgreSQL error messages are usually spot on. This one is spot on.

Just add the namespace:

System.Windows.forms 

to your web application reference or what ever, and you have the access to your:

MessageBox.Show("Here is my message");

I tried it and it worked.

Good luck.

html {
  position:relative;
  top:0px;
  left:0px;
  overflow:auto;
  height:auto
}

add this as default to your css

.class-on-html{
  position:fixed;
  top:0px;
  left:0px;
  overflow:hidden;
  height:100%;
}

toggleClass this class to to cut page

when you turn off this class first line will call scrolling bar back

Whenever I use the moment.js library I specify the desired format this way:

moment(<your Date goes here>).format("DD-MMM-YYYY")

or

moment(<your Date goes here>).format("DD/MMM/YYYY")

... etc I hope you get the idea

Inside the format function, you put the desired format. The example above will get rid of all unwanted elements from the date such as minutes and seconds

As I understand Copy-Item -Exclude then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item as in

Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item  -Path $copyAdmin -Destination $AdminPath -Recurse -force

Product Version may be preferred if you're using versioning via GitVersion or other versioning software.

To get this from within your class library you can call System.Diagnostics.FileVersionInfo.ProductVersion:

using System.Diagnostics;
using System.Reflection;

//...

var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var productVersion = FileVersionInfo.GetVersionInfo(assemblyLocation).ProductVersion

I would use your suggested code, but with a slight simplification:

KeyGenerator keyGen = KeyGenerator.getInstance("AES");
keyGen.init(256); // for example
SecretKey secretKey = keyGen.generateKey();

Let the provider select how it plans to obtain randomness - don't define something that may not be as good as what the provider has already selected.

This code example assumes (as Maarten points out below) that you've configured your java.security file to include your preferred provider at the top of the list. If you want to manually specify the provider, just call KeyGenerator.getInstance("AES", "providerName");.

For a truly secure key, you need to be using a hardware security module (HSM) to generate and protect the key. HSM manufacturers will typically supply a JCE provider that will do all the key generation for you, using the code above.

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

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

It could be done by getting the page title by Selenium and do assertion by using TestNG.

1. Import Assert class in the import section:

   `import org.testng.Assert;`
   

2. Create a WebDriver object:

   WebDriver driver=new FirefoxDriver();

3. Apply this to assert the title of the page:

   Assert.assertEquals("Expected page title", driver.getTitle());

I would really opt for FlowPaper, especially their new Elements mode that can be found here : https://flowpaper.com/demo/

It flattens the PDFs significantly at the same time as keeping text sharp which means that it will load much faster on mobile devices

Starting from the decoded base64 data of an OpenSSL rsa-ssh Key, i've been able to guess a format:

• 00 00 00 01: four byte length prefix (1 byte)
• 25: RSA Exponent (e): 25
• 00 00 01 00: four byte length prefix (256 bytes)

• RSA Modulus (n):

The closest validation of my theory i can find it from RFC 4253:

The "ssh-rsa" key format has the following specific encoding:

  string    "ssh-rsa"
  mpint     e
  mpint     n

Here the 'e' and 'n' parameters form the signature key blob.

But it doesn't explain the length prefixes.

Taking the random RSA PUBLIC KEY i found (in the question), and decoding the base64 into hex:

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:

A.1.1 RSA public key syntax

An RSA public key should be represented with the ASN.1 type RSAPublicKey:

  RSAPublicKey ::= SEQUENCE {
     modulus           INTEGER,  -- n
     publicExponent    INTEGER   -- e
  }

The fields of type RSAPublicKey have the following meanings:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

Using Microsoft's excellent (and the only real) ASN.1 documentation:

30 82 01 0a       ;SEQUENCE (0x010A bytes: 266 bytes)
|  02 82 01 01    ;INTEGER  (0x0101 bytes: 257 bytes)

giving the public key modulus and exponent:

• modulus = 0xfb1199ff0733f6e805a4fd3b36ca68...837a63
• exponent = 65,537

Update: My expanded form of this answer in another question

Try this:

    Rect rect = new Rect();
    Window win = this.getWindow();
    win.getDecorView().getWindowVisibleDisplayFrame(rect);
    int statusBarHeight = rect.top;
    int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
    int titleBarHeight = contentViewTop - statusBarHeight;
    Log.d("ID-ANDROID-CONTENT", "titleBarHeight = " + titleBarHeight );

it didn't work for me in the onCreate method for the activity, but did when I put it in an onClickListener and gave me a measurement of 25

IMO this link from Yochai Timmer was very good and relevant but painful to read. I wrote a summary.

Yochai, if you ever read this, please see the note at the end.

For the original post read : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs

Error

LINK : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs; use /NODEFAULTLIB:library

Meaning

one part of the system was compiled to use a single threaded standard (libc) library with debug information (libcd) which is statically linked

while another part of the system was compiled to use a multi-threaded standard library without debug information which resides in a DLL and uses dynamic linking

How to resolve

• Ignore the warning, after all it is only a warning. However, your program now contains multiple instances of the same functions.

• Use the linker option /NODEFAULTLIB:lib. This is not a complete solution, even if you can get your program to link this way you are ignoring a warning sign: the code has been compiled for different environments, some of your code may be compiled for a single threaded model while other code is multi-threaded.

• [...] trawl through all your libraries and ensure they have the correct link settings

In the latter, as it in mentioned in the original post, two common problems can arise :

• You have a third party library which is linked differently to your application.

• You have other directives embedded in your code: normally this is the MFC. If any modules in your system link against MFC all your modules must nominally link against the same version of MFC.

For those cases, ensure you understand the problem and decide among the solutions.

Note : I wanted to include that summary of Yochai Timmer's link into his own answer but since some people have trouble to review edits properly I had to write it in a separate answer. Sorry

There are several libraries available solving this problem, but the simplest is probably to use Boost Tokenizer:

#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>
#include <boost/foreach.hpp>

typedef boost::tokenizer<boost::char_separator<char> > tokenizer;

std::string str("denmark;sweden;india;us");
boost::char_separator<char> sep(";");
tokenizer tokens(str, sep);

BOOST_FOREACH(std::string const& token, tokens)
{
    std::cout << "<" << *tok_iter << "> " << "\n";
}

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

First, I can give you the answer for one table:

The trouble with all these INTO OUTFILE or --tab=tmpfile (and -T/path/to/directory) answers is that it requires running mysqldump on the same server as the MySQL server, and having those access rights.

My solution was simply to use mysql (not mysqldump) with the -B parameter, inline the SELECT statement with -e, then massage the ASCII output with sed, and wind up with CSV including a header field row:

Example:

 mysql -B -u username -p password database -h dbhost -e "SELECT * FROM accounts;" \
 | sed "s/\"/\"\"/g;s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"

"id","login","password","folder","email" "8","mariana","xxxxxxxxxx","mariana","" "3","squaredesign","xxxxxxxxxxxxxxxxx","squaredesign","[email protected]" "4","miedziak","xxxxxxxxxx","miedziak","[email protected]" "5","Sarko","xxxxxxxxx","Sarko","" "6","Logitrans Poland","xxxxxxxxxxxxxx","LogitransPoland","" "7","Amos","xxxxxxxxxxxxxxxxxxxx","Amos","" "9","Annabelle","xxxxxxxxxxxxxxxx","Annabelle","" "11","Brandfathers and Sons","xxxxxxxxxxxxxxxxx","BrandfathersAndSons","" "12","Imagine Group","xxxxxxxxxxxxxxxx","ImagineGroup","" "13","EduSquare.pl","xxxxxxxxxxxxxxxxx","EduSquare.pl","" "101","tmp","xxxxxxxxxxxxxxxxxxxxx","_","[email protected]"

Add a > outfile.csv at the end of that one-liner, to get your CSV file for that table.

Next, get a list of all your tables with

mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"

From there, it's only one more step to make a loop, for example, in the Bash shell to iterate over those tables:

 for tb in $(mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"); do
     echo .....;
 done

Between the do and ; done insert the long command I wrote in Part 1 above, but substitute your tablename with $tb instead.

If you just want to rename and don't mind using an external tool, then you can use rnm. The command would be:

#on current folder
rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' *

-dp -1 will make it recursive to all subdirectories.

-fo implies file only mode.

-ssf '_dbg' searches for files with _dbg in the filename.

-rs '/_dbg//' replaces _dbg with empty string.

You can run the above command with the path of the CURRENT_FOLDER too:

rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' /path/to/the/directory

.loc accept row and column selectors simultaneously (as do .ix/.iloc FYI) This is done in a single pass as well.

In [1]: df = DataFrame(np.random.rand(4,5), columns = list('abcde'))

In [2]: df
Out[2]: 
          a         b         c         d         e
0  0.669701  0.780497  0.955690  0.451573  0.232194
1  0.952762  0.585579  0.890801  0.643251  0.556220
2  0.900713  0.790938  0.952628  0.505775  0.582365
3  0.994205  0.330560  0.286694  0.125061  0.575153

In [5]: df.loc[df['c']>0.5,['a','d']]
Out[5]: 
          a         d
0  0.669701  0.451573
1  0.952762  0.643251
2  0.900713  0.505775

And if you want the values (though this should pass directly to sklearn as is); frames support the array interface

In [6]: df.loc[df['c']>0.5,['a','d']].values
Out[6]: 
array([[ 0.66970138,  0.45157274],
       [ 0.95276167,  0.64325143],
       [ 0.90071271,  0.50577509]])

Unless someone can recommend a free tool to do this, you can achieve this with ReSharper:

ReSharper >> Options... >> Languages/C# >> Line Breaks and Wrapping

• Check "Wrap long lines"
• Set "Right Margin (columns)" to the required value (default is 120)

Hope that helps.

Try this too in addition to MahmoudS comments. Change the maven compiler source and target in your pom.xml to the java version which you are using. Say 1.7 for jdk7

<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>

This is extension to answers above, if your xml has namespace defined (xmlns) then you will get a nasty side effect when adding children - xmlns = "" being added to your new child element.

What you want to do (assuming element you are adding belongs to same namespace as his parent) is to take namespace from parent element parentElement.GetDefaultNamespace().

var child = new XElement(parentElement.GetDefaultNamespace()+"Snippet", new XAttribute("Attr1", "42"), new XAttribute("Attr2", "22"));
child.Add(new XAttribute("Attr3", "777"));
parentElement.Add(child);

for parent elements with multiple namespaces you can choose which one to use by changing from parentElement.GetDefaultNamespace()+"Snippet" to parentElement.GetNamespaceOfPrefix("namespacePrefixThatGoesWithColon")+"Snippet" e.g

var child = new XElement(parentElement.GetNamespaceOfPrefix("namespacePrefixThatGoesWithColon")+"Snippet", new XAttribute("Attr1", "42"), new XAttribute("Attr2", "22"));

TLS client certificates are not sent in HTTP headers. They are transmitted by the client as part of the TLS handshake, and the server will typically check the validity of the certificate during the handshake as well.

If the certificate is accepted, most web servers can be configured to add headers for transmitting the certificate or information contained on the certificate to the application. Environment variables are populated with certificate information in Apache and Nginx which can be used in other directives for setting headers.

As an example of this approach, the following Nginx config snippet will validate a client certificate, and then set the SSL_CLIENT_CERT header to pass the entire certificate to the application. This will only be set when then certificate was successfully validated, so the application can then parse the certificate and rely on the information it bears.

server {
    listen 443 ssl;
    server_name example.com;
    ssl_certificate /path/to/chainedcert.pem;  # server certificate
    ssl_certificate_key /path/to/key;          # server key

    ssl_client_certificate /path/to/ca.pem;    # client CA
    ssl_verify_client on;
    proxy_set_header SSL_CLIENT_CERT $ssl_client_cert;

    location / {
        proxy_pass http://localhost:3000;
    }
}

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

Cheers!

You can use the Google Docs PDF-viewing widget, if you don't mind having them host the "application" itself.

This is how can you have automatic & flexible createDate/lastModified fields using triggers:

First define them like this:

CREATE TABLE `entity` (
  `entityid` int(11) NOT NULL AUTO_INCREMENT,
  `createDate` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `lastModified` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
  `name` varchar(255) DEFAULT NULL,
  `comment` text,
  PRIMARY KEY (`entityid`),
)

Then add these triggers:

DELIMITER ;;
CREATE trigger entityinsert BEFORE INSERT ON entity FOR EACH ROW BEGIN SET NEW.createDate=IF(ISNULL(NEW.createDate) OR NEW.createDate='0000-00-00 00:00:00', CURRENT_TIMESTAMP, IF(NEW.createDate<CURRENT_TIMESTAMP, NEW.createDate, CURRENT_TIMESTAMP));SET NEW.lastModified=NEW.createDate; END;;
DELIMITER ;
CREATE trigger entityupdate BEFORE UPDATE ON entity FOR EACH ROW SET NEW.lastModified=IF(NEW.lastModified<OLD.lastModified, OLD.lastModified, CURRENT_TIMESTAMP);

• If you insert without specifying createDate or lastModified, they will be equal and set to the current timestamp.
• If you update them without specifying createDate or lastModified, the lastModified will be set to the current timestamp.

But here's the nice part:

• If you insert, you can specify a createDate older than the current timestamp, allowing imports from older times to work well (lastModified will be equal to createDate).
• If you update, you can specify a lastModified older than the previous value ('0000-00-00 00:00:00' works well), allowing to update an entry if you're doing cosmetic changes (fixing a typo in a comment) and you want to keep the old lastModified date. This will not modify the lastModified date.

I tried this code to accept files using Ajax and on submit file gets store using my php file. Code modified slightly to work. (Uploaded Files: PDF,JPG)

function verify1() {
    jQuery.ajax({
        type: 'POST',
        url:"functions.php",
        data: new FormData($("#infoForm1")[0]),
        processData: false, 
        contentType: false, 
        success: function(returnval) {
             $("#show1").html(returnval);
             $('#show1').show();
         }
    });
}

Just print the file details and check. You will get Output. If error let me know.

First the quick and dirty way, and second the precise way (recognizing daylight's savings or not).

import time
time.ctime() # 'Mon Oct 18 13:35:29 2010'
time.strftime('%l:%M%p %Z on %b %d, %Y') # ' 1:36PM EDT on Oct 18, 2010'
time.strftime('%l:%M%p %z on %b %d, %Y') # ' 1:36PM EST on Oct 18, 2010'

I work through these two ways without any problem:

<pre>
<code>
 ... java code, even including annotations

</pre>

and

<pre class="code">

</pre>

Of course the latter is more simplest and observe the class="code" part

Database table

Having the following blog database table storing the blogs hosted by our platform:

And, we have two blogs currently hosted:

Getting our report without using the SQL LATERAL JOIN

We need to build a report that extracts the following data from the blog table:

• the blog id
• the blog age, in years
• the date for the next blog anniversary
• the number of days remaining until the next anniversary.

If you're using PostgreSQL, then you have to execute the following SQL query:

SELECT
  b.id as blog_id,
  extract(
    YEAR FROM age(now(), b.created_on)
  ) AS age_in_years,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
ORDER BY blog_id

As you can see, the age_in_years has to be defined three times because you need it when calculating the next_anniversary and days_to_next_anniversary values.

And, that's exactly where LATERAL JOIN can help us.

Getting the report using the SQL LATERAL JOIN

The following relational database systems support the LATERAL JOIN syntax:

• Oracle since 12c
• PostgreSQL since 9.3
• MySQL since 8.0.14

SQL Server can emulate the LATERAL JOIN using CROSS APPLY and OUTER APPLY.

LATERAL JOIN allows us to reuse the age_in_years value and just pass it further when calculating the next_anniversary and days_to_next_anniversary values.

The previous query can be rewritten to use the LATERAL JOIN, as follows:

SELECT
  b.id as blog_id,
  age_in_years,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
CROSS JOIN LATERAL (
  SELECT
    cast(
      extract(YEAR FROM age(now(), b.created_on)) AS int
    ) AS age_in_years
) AS t
ORDER BY blog_id

And, the age_in_years value can be calculated one and reused for the next_anniversary and days_to_next_anniversary computations:

Much better, right?

The age_in_years is calculated for every record of the blog table. So, it works like a correlated subquery, but the subquery records are joined with the primary table and, for this reason, we can reference the columns produced by the subquery.

Like so many of you, I've been struggling with this for a while. The solution ultimately had to do with the div containing the UL. All suggestions on altering padding, width, etc. of the UL had no effect, but the following did.

It's all about the margin:0 auto; on the containing div. I hope this helps some people, and thanks to everyone else who already suggested this in combination with other things.

.divNav
{
    width: 99%;
    text-align:center;
    margin:0 auto; 
}

.divNav ul
{ 
    display:inline-block; 
    list-style:none;
    zoom: 1;
}

.divNav ul li 
{
    float:left;
    margin-right: .8em;       
    padding: 0; 
}

.divNav a,  #divNav a:visited
{
    width: 7.5em;
    display: block; 
    border: 1px solid #000;
    border-bottom:none;
    padding: 5px; 
    background-color:#F90;
    text-decoration: none;
    color:#FFF;
    text-align: center;
    font-family:Verdana, Geneva, sans-serif;
    font-size:1em;
}

Create Button and add image as its background swift 4

     let img = UIImage(named: "imgname")
     let myButton = UIButton(type: UIButtonType.custom)
     myButton.frame = CGRect.init(x: 10, y: 10, width: 100, height: 45)
     myButton.setImage(img, for: .normal)
     myButton.addTarget(self, action: #selector(self.buttonClicked(_:)), for: UIControlEvents.touchUpInside)
     self.view.addSubview(myButton)

To put a require rule on a select list you just need an option with an empty value

<option value="">Year</option>

then just applying required on its own is enough

<script>
    $(function () {
        $("form").validate();
    });
</script>

with form

<form>
<select name="year" id="year" class="required">
    <option value="">Year</option>
    <option value="1">1919</option>
    <option value="2">1920</option>
    <option value="3">1921</option>
    <option value="4">1922</option>
</select>
<input type="submit" />
</form>

It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.

In 'Path Variables' create a variable for example ANALYTICS_VERSION.

In a 'Run Configuration' under 'Environment Variables' add for example the following:

ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin

To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:

APP_HOME=$APP_HOME$

I have almost same issue with VideoView. I try to play a video (1080*1080) with a Nexus 5 and it works well, but the same video on Galaxy ace 2 give me the Cannot Play Video message.

But I notice that with a lower definition of the video (120x120), it works fine.

So perhaps just a matter of "Size" (and especially with blonde_secretary.3gp video ....)

If you have newly upgraded your php version you might be forget to restart your webserver service.

The legend titles can be labeled by specific aesthetic.

This can be achieved using the guides() or labs() functions from ggplot2 (more here and here). It allows you to add guide/legend properties using the aesthetic mapping.

Here's an example using the mtcars data set and labs():

ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
  geom_point() +
  labs(x="miles per gallon", y="displacement", size="horsepower", 
       col="# of cylinders", shape="# of gears")

Answering the OP's question using guides():

# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")

# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) + 
  geom_point(size=5) +
  labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
  scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
  theme_bw() +
  guides(color=guide_legend("my title"))  # add guide properties by aesthetic

You don't appear to have write permission to the /tmp directory on your server. This is a bit weird, but you can work around it. Before the call to session_start() put in a call to session_save_path() and give it the name of a directory writable by the server. Details are here.

Edit: 2013.01.15 - If your server will support it, use martinstoeckli's solution instead.

Everyone wants to make this more complicated than it is. The crypt() function does most of the work.

function blowfishCrypt($password,$cost)
{
    $chars='./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
    $salt=sprintf('$2y$%02d$',$cost);
//For PHP < PHP 5.3.7 use this instead
//    $salt=sprintf('$2a$%02d$',$cost);
    //Create a 22 character salt -edit- 2013.01.15 - replaced rand with mt_rand
    mt_srand();
    for($i=0;$i<22;$i++) $salt.=$chars[mt_rand(0,63)];
    return crypt($password,$salt);
}

Example:

$hash=blowfishCrypt('password',10); //This creates the hash
$hash=blowfishCrypt('password',12); //This creates a more secure hash
if(crypt('password',$hash)==$hash){ /*ok*/ } //This checks a password

I know it should be obvious, but please don't use 'password' as your password.

select * from [schema_name].sys.tables

This should work. Make sure you are on the server which consists of your "[schema_name]"

This is called Double checked locking mechanism, first, we will check whether the instance is created or not. If not then only we will synchronize the method and create the instance. It will drastically improve the performance of the application. Performing lock is heavy. So to avoid the lock first we need to check the null value. This is also thread safe and it is the best way to achieve the best performance. Please have a look at the following code.

public sealed class Singleton
{
    private static readonly object Instancelock = new object();
    private Singleton()
    {
    }
    private static Singleton instance = null;

    public static Singleton GetInstance
    {
        get
        {
            if (instance == null)
            {
                lock (Instancelock)
                {
                    if (instance == null)
                    {
                        instance = new Singleton();
                    }
                }
            }
            return instance;
        }
    }
}

if you state a.redLink{color:red;} then to keep this on hover and such add a.redLink:hover{color:red;} This will make sure no other hover states will change the color of your links

var myString = "Hello, how are you?";
myString.slice(0,8);

Better yet, configure the editor to something you are comfortable with (gedit as an example):

git config --global core.editor "gedit"

You can read the current configuration like this:

git config core.editor

You can also add the commit message from the command line.

git commit -m "blablabla"

and the editor will not be opened in the first place.

To do this in the Code Behind (VB.NET)

Dim txtCol As New DataGridTextColumn

Dim style As New Style(GetType(TextBlock))
Dim tri As New Trigger With {.Property = TextBlock.TextProperty, .Value = "John"}
tri.Setters.Add(New Setter With {.Property = TextBlock.BackgroundProperty, .Value = Brushes.Green})
style.Triggers.Add(tri)

xtCol.ElementStyle = style

[What you have is just an object, not a "json-object". JSON is a textual notation. What you've quoted is JavaScript code using an array initializer and an object initializer (aka, "object literal syntax").]

If you can rely on having ECMAScript5 features available, you can use the Object.keys function to get an array of the keys (property names) in an object. All modern browsers have Object.keys (including IE9+).

Object.keys(jsonData).forEach(function(key) {
    var value = jsonData[key];
    // ...
});

The rest of this answer was written in 2011. In today's world, A) You don't need to polyfill this unless you need to support IE8 or earlier (!), and B) If you did, you wouldn't do it with a one-off you wrote yourself or grabbed from an SO answer (and probably shouldn't have in 2011, either). You'd use a curated polyfill, possibly from es5-shim or via a transpiler like Babel that can be configured to include polyfills (which may come from es5-shim).

Here's the rest of the answer from 2011:

Note that older browsers won't have it. If not, this is one of the ones you can supply yourself:

if (typeof Object.keys !== "function") {
    (function() {
        var hasOwn = Object.prototype.hasOwnProperty;
        Object.keys = Object_keys;
        function Object_keys(obj) {
            var keys = [], name;
            for (name in obj) {
                if (hasOwn.call(obj, name)) {
                    keys.push(name);
                }
            }
            return keys;
        }
    })();
}

That uses a for..in loop (more info here) to loop through all of the property names the object has, and uses Object.prototype.hasOwnProperty to check that the property is owned directly by the object rather than being inherited.

(I could have done it without the self-executing function, but I prefer my functions to have names, and to be compatible with IE you can't use named function expressions [well, not without great care]. So the self-executing function is there to avoid having the function declaration create a global symbol.)

$arr1 = array(
   "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
   "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
   "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
   "3" => array("fid" => 1, "tid" => 7, "name" => "Xi"),
   "4" => array("fid" => 2, "tid" => 9, "name" => "Xigua")
);

if you want to convert this array as following:

$arr2 = array(
   "0" => array(
          "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
          "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
          "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
          "3" => array("fid" => 1, "tid" => 7, "name" => "Xi")
    ),

    "1" => array(
          "0" =>array("fid" => 2, "tid" => 9, "name" => "Xigua")
     )
);

so, my answer will be like this:

$outer_array = array();
$unique_array = array();
foreach($arr1 as $key => $value)
{
    $inner_array = array();

    $fid_value = $value['fid'];
    if(!in_array($value['fid'], $unique_array))
    {
            array_push($unique_array, $fid_value);
            unset($value['fid']);
            array_push($inner_array, $value);
            $outer_array[$fid_value] = $inner_array;


    }else{
            unset($value['fid']);
            array_push($outer_array[$fid_value], $value);

    }
}
var_dump(array_values($outer_array));

hope this answer will help somebody sometime.
