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

For example:

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

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

Similarly,

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

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

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

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

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

Class-based decorators use __call__ to reference the wrapped function. E.g.:

class Deco(object):
    def __init__(self,f):
        self.f = f
    def __call__(self, *args, **kwargs):
        print args
        print kwargs
        self.f(*args, **kwargs)

There is a good description of the various options here at Artima.com

I vote for a third solution. I use this in my projects and Symfony uses something like this too:

public function __call($val, $x) {
    if(substr($val, 0, 3) == 'get') {
        $varname = strtolower(substr($val, 3));
    }
    else {
        throw new Exception('Bad method.', 500);
    }
    if(property_exists('Yourclass', $varname)) {
        return $this->$varname;
    } else {
        throw new Exception('Property does not exist: '.$varname, 500);
    }
}

This way you have automated getters (you can write setters too), and you only have to write new methods if there is a special case for a member variable.

I have run into the same problem as w00, but I didn't had the freedom to rewrite the base functionality of the component in which this problem (E_NOTICE) occured. I've been able to fix the issue using an ArrayObject in stead of the basic type array(). This will return an object, which will defaulty be returned by reference.

Apart from all the answers given, I would like to add few points :-

1) __repr__() is invoked when you simply write object's name on interactive python console and press enter.

2) __str__() is invoked when you use object with print statement.

3) In case, if __str__ is missing, then print and any function using str() invokes __repr__() of object.

4) __str__() of containers, when invoked will execute __repr__() method of its contained elements.

5) str() called within __str__() could potentially recurse without a base case, and error on maximum recursion depth.

6) __repr__() can call repr() which will attempt to avoid infinite recursion automatically, replacing an already represented object with ....

Best use magic set/get methods with predefined custom set/get Methods as in example below. This way you can combine best of two worlds. In terms of speed I agree that they are a bit slower but can you even feel the difference. Example below also validate the data array against predefined setters.

"The magic methods are not substitutes for getters and setters. They just allow you to handle method calls or property access that would otherwise result in an error."

This is why we should use both.

CLASS ITEM EXAMPLE

    /*
    * Item class
    */
class Item{
    private $data = array();

    function __construct($options=""){ //set default to none
        $this->setNewDataClass($options); //calling function
    }

    private function setNewDataClass($options){
        foreach ($options as $key => $value) {
            $method = 'set'.ucfirst($key); //capitalize first letter of the key to preserve camel case convention naming
            if(is_callable(array($this, $method))){  //use seters setMethod() to set value for this data[key];      
                $this->$method($value); //execute the setters function
            }else{
                $this->data[$key] = $value; //create new set data[key] = value without seeters;
            }   
        }
    }

    private function setNameOfTheItem($value){ // no filter
        $this->data['name'] = strtoupper($value); //assign the value
        return $this->data['name']; // return the value - optional
    }

    private function setWeight($value){ //use some kind of filter
        if($value >= "100"){ 
            $value = "this item is too heavy - sorry - exceeded weight of maximum 99 kg [setters filter]";
        }
        $this->data['weight'] = strtoupper($value); //asign the value
        return $this->data['weight']; // return the value - optional
    }

    function __set($key, $value){
        $method = 'set'.ucfirst($key); //capitalize first letter of the key to preserv camell case convention naming
        if(is_callable(array($this, $method))){  //use seters setMethod() to set value for this data[key];      
            $this->$method($value); //execute the seeter function
        }else{
            $this->data[$key] = $value; //create new set data[key] = value without seeters;
        }
    }

    function __get($key){
        return $this->data[$key];
    }

    function dump(){
        var_dump($this);
    }
}

$item = new Item($data);
$item->dump();

$item->somethingThatDoNotExists = 0; // this key (key, value) will trigger magic function __set() without any control or check of the input,

$item->dump();

$item->weight = 111; // this key will trigger predefined setter function of a class - setWeight($value) - value invalid - will generate warning.

I wanted to comment on @Ionica Bizau, but I don't have enough reputation.
To give a reply to your question about javascript code:
What you need to do is get the parent's element height (minus any elements that take up space) and apply that to the child elements.

function wrapperHeight(){
    var height = $(window).outerHeight() - $('#header').outerHeight(true);
    $('.wrapper').css({"max-height":height+"px"});      
}

Note
window could be replaced by ".container" if that one has no floated children or has a fix to get the correct height calculated. This solution uses jQuery.

You need to use the NVL function, e.g.

SUM(NVL(regular,0) + NVL(overtime,0))

Yes, you can do it by specifying the comparison method. The advantage is the sorted object don't have to be IComparable

   aListOfObjects.Sort((x, y) =>
   {
       int result = x.A.CompareTo(y.A);
       return result != 0 ? result : x.B.CompareTo(y.B);
   });

You can turn off foreign key checks:

SET FOREIGN_KEY_CHECKS = 0;

/* DO WHAT YOU NEED HERE */

SET FOREIGN_KEY_CHECKS = 1;

Please make sure to NOT use this on production and have a backup.

Set the href attribute as href="javascript:;"

<ul class="product-info">
  <li>
   <a href="javascript:;">YOU CLICK THIS TO SHOW/HIDE</a>
  <div class="toggle">
    <p>CONTENT TO SHOW/HIDE</p>
  </div>
 </li>
</ul>

It's an asynchronous request, meaning once it's sent it's out there.

In case your server is starting a very expensive operation due to the AJAX request, the best you can do is open your server to listen for cancel requests, and send a separate AJAX request notifying the server to stop whatever it's doing.

Otherwise, simply ignore the AJAX response.

     would be a work around if you're only after the spacing.

You could do it with the requests module as well:

url = 'http://winterolympicsmedals.com/medals.csv'
r = requests.get(url)
text = r.iter_lines()
reader = csv.reader(text, delimiter=',')

You should use require_once and include_once. Inside parent.php use

include_once 'database.php';

And inside child1.php and child2.php use

include_once 'parent.php';

if I understand you right (not sure), the start parameter /D should help you:

start "cmd" /D %PathName% %comd%

/D sets the start-directory (see start /?)

You probably need to put it in a CDATA block to preserve whitespace

<?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="dummy.xsl"?>   
   <item>      
      <summary>
         <![CDATA[Tootsie roll tiramisu macaroon wafer carrot cake.                       
            Danish topping sugar plum tart bonbon caramels cake.]]>
      </summary>   
   </item> 

From the RFC 4648:

Base encoding of data is used in many situations to store or transfer data in environments that, perhaps for legacy reasons, are restricted to US-ASCII data.

So it depends on the purpose of usage of the encoded data if the data should be considered as dangerous.

But if you’re just looking for a regular expression to match Base64 encoded words, you can use the following:

^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$

Just add a . to it:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

That means: check out to current directory.

Since you don't care, I chose the max ID for each number.

select tbl.* from tbl
inner join (
select max(id) as maxID, number from tbl group by number) maxID
on maxID.maxID = tbl.id

Query Explanation

 select 
    tbl.*  -- give me all the data from the base table (tbl) 
 from 
    tbl    
    inner join (  -- only return rows in tbl which match this subquery
        select 
            max(id) as maxID -- MAX (ie distinct) ID per GROUP BY below
        from 
            tbl 
        group by 
            NUMBER            -- how to group rows for the MAX aggregation
    ) maxID
        on maxID.maxID = tbl.id -- join condition ie only return rows in tbl 
                                -- whose ID is also a MAX ID for a given NUMBER

A formula to return either the first word or all the other words.

=IF(ISERROR(FIND(" ",TRIM(A2),1)),TRIM(A2),MID(TRIM(A2),FIND(" ",TRIM(A2),1),LEN(A2)))

Examples and results

Text                  Description                      Results

                      Blank 
                      Space 
some                  Text no space                some
some text             Text with space                  text
 some                 Text with leading space          some
some                  Text with trailing space         some
some text some text   Text with multiple spaces        text some text

Comments on Formula:

• The TRIM function is used to remove all leading and trailing spaces. Duplicate spacing within the text is also removed.
• The FIND function then finds the first space
• If there is no space then the trimmed text is returned
• Otherwise the MID function is used to return any text after the first space

I don't think there's a way to do this, unless you're writing a browser extension. You could try using window.open and hoping that the user has their browser set to open new windows in new tabs.

= f.input_field :title, as: :hidden, value: "some value"

Is also an option. Note, however, that it skips any wrapper defined for your form builder.

. (dot) files are hidden by default on Unix/Linux systems. Most likely, if you know they are .htaccess files, then they are probably in the root folder for the website.

If you are using a command line (terminal) to access, then they will only show up if you use:

ls -a

If you are using a GUI application, look for a setting to "show hidden files" or something similar.

If you still have no luck, and you are on a terminal, you can execute these commands to search the whole system (may take some time):

cd /
find . -name ".htaccess"

This will list out any files it finds with that name.

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }
});

Notice that now you access it through rootView view:

Button buttonClick = (Button)rootView.findViewById(R.id.button);

otherwise you would get again NullPointerException.

I had the following

document.getElementById("search-button") != null

which worked fine in all browsers except ie8. ( I didnt check ie6 or ie7)

I changed it to

document.getElementById("searchBtn") != null

and updated the id attribute on the field in my html and it now works in ie8

Depending on the complexity for the database compared to developer complexity, it may be simpler to do many SELECT calls.

Try running some database statistics against both the JOIN and the multiple SELECTS. See if in your environment the JOIN is faster/slower than the SELECT.

Then again, if changing it to a JOIN would mean an extra day/week/month of dev work, I'd stick with multiple SELECTs

put a int infront of the all the voxelCoord's...Like this below :

patch = numpyImage [int(voxelCoord[0]),int(voxelCoord[1])- int(voxelWidth/2):int(voxelCoord[1])+int(voxelWidth/2),int(voxelCoord[2])-int(voxelWidth/2):int(voxelCoord[2])+int(voxelWidth/2)]

Try if this works for you. This works on FF, IE8+ and chrome. The else part applies for non-firefox browsers. Though this gives you a zoom effect, it does not actually modify the zoom value at browser level.

    var currFFZoom = 1;
    var currIEZoom = 100;

    $('#plusBtn').on('click',function(){
        if ($.browser.mozilla){
            var step = 0.02;
            currFFZoom += step; 
            $('body').css('MozTransform','scale(' + currFFZoom + ')');
        } else {
            var step = 2;
            currIEZoom += step;
            $('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });

    $('#minusBtn').on('click',function(){
        if ($.browser.mozilla){
            var step = 0.02;
            currFFZoom -= step;                 
            $('body').css('MozTransform','scale(' + currFFZoom + ')');

        } else {
            var step = 2;
            currIEZoom -= step;
            $('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });

Try to use getActivity(); This will solve your problem.

JQuery 10.1.2 has a nice show and hide functions that encapsulate the behavior you are talking about. This would save you having to write a new function or keep track of css classes.

$("new").show();

$("new").hide();

Use title attribute instead of alt

<img
  height="90"
  width="90"
  src="http://www.google.com/intl/en_ALL/images/logos/images_logo_lg12.gif"
  title="Image Not Found"
/>

Try this in Java 8:

Optional first = query.getResultList().stream().findFirst();

I'm pretty sure in is having higher precedence than , so your statement is being interpreted as 'a', ('b' in ['b' ...]), which then evaluates to 'a', True since 'b' is in the array.

See previous answer for how to do what you want.

From the Android Studio download page:

Caution: Android Studio is currently available as an early access preview. Several features are either incomplete or not yet implemented and you may encounter bugs. If you are not comfortable using an unfinished product, you may want to instead download (or continue to use) the ADT Bundle (Eclipse with the ADT Plugin).

You can set the figure size if you explicitly create the figure with

plt.figure(figsize=(3,4))

You need to set figure size before calling plt.plot() To change the format of the saved figure just change the extension in the file name. However, I don't know if any of matplotlib backends support tiff

The answer by Aaron is the best and is working for me :) I would vote it up but sadly I can't (missing reputation).

I've to say testing private methods is the only way to use them and have clean code on the other side.

For example:

class Something {
  save(){
    const data = this.getAllUserData()
    if (this.validate(data))
      this.sendRequest(data)
  }
  private getAllUserData () {...}
  private validate(data) {...}
  private sendRequest(data) {...}
}

It' makes a lot of sense to not test all these methods at once because we would need to mock out those private methods, which we can't mock out because we can't access them. This means we need a lot of configuration for a unit test to test this as a whole.

This said the best way to test the method above with all dependencies is an end to end test, because here an integration test is needed, but the E2E test won't help you if you are practicing TDD (Test Driven Development), but testing any method will.

<script>var myVar = 15;</script>
<input id="EditBanner" type="button" value="Edit Image" onclick="EditBanner(myVar);"/>

You can use Joshua's solution but I think you need Elts_int <- as.matrix(tmp_int)

Or for loops:

z <- 1 ## Initialize
counter <- 1 ## Initialize
for(y in 1:48) { ## Assuming 48 columns otherwise, swap 48 and 32
for (x in 1:32) {  
z[counter] <- tmp_int[x,y]
counter <- 1 + counter
}
}

z is a 1d vector.

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

You can use WMIC or SCHTASKS (which means no third party software is needed):

1) SCHTASKS:

SCHTASKS /s remote_machine /U username /P password /create /tn "On demand demo" /tr "C:\some.bat" /sc ONCE /sd 01/01/1910 /st 00:00
SCHTASKS /s remote_machine /U username /P password /run /TN "On demand demo" 

2) WMIC (wmic will return the pid of the started process)

WMIC /NODE:"remote_machine" /user user /password password process call create "c:\some.bat","c:\exec_dir"

Best thing is

File.AppendAllText("c:\\file.txt","Your Text");

SHELL is an environment variable, and so it's not the most reliable for what you're trying to figure out. If your tool is using a shell which doesn't set it, it will retain its old value.

Use ps to figure out what's really going on.

Simply change the default 50px navbar-height by including this to your variable overrides.

You can find this default navbar-height on line 365 and 360 on bootstrap's SASS and LESS variables files respectively.

File location, LESS: bootstrap/less/variable.less

If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

If you wish more look at: http://developer.android.com/intl/pt-br/guide/topics/resources/string-resource.html#FormattingAndStyling

Ahah! Cade is on the money.

An artifact in TOAD prints \r\n as two placeholder 'blob' characters, but prints a single \r also as two placeholders. The 1st step toward a solution is to use ..

REPLACE( col_name, CHR(13) || CHR(10) )

.. but I opted for the slightly more robust ..

REPLACE(REPLACE( col_name, CHR(10) ), CHR(13) )

.. which catches offending characters in any order. My many thanks to Cade.

Here's a very simple way. Create two files:

protect-this.php

<?php

    $password = 'MYPASS';

    if (empty($_COOKIE['password']) || $_COOKIE['password'] !== $password) {
        // Password not set or incorrect. Send to login.php.
        header('Location: login.php');
        exit;
    }
?>

login.php:

<?php
    /* Your password */
    $password = 'MYPASS';

    /* Redirects here after login */
    $redirect_after_login = 'index.php';

    /* Will not ask password again for */
    $remember_password = strtotime('+30 days'); // 30 days

    if (isset($_POST['password']) && $_POST['password'] == $password) {
        setcookie("password", $password, $remember_password);
        header('Location: ' . $redirect_after_login);

Then require protect-this.php on the TOP of the files you want to protect:

// Password protect this content
require_once('protect-this.php');

Example result:

After filling the correct password, user is taken to index.php. The password is stored for 30 days.

PS: It's not focused to be secure, but to be pratical. A hacker can brute-force this. Use it to keep normal users away. Don't use it to protect sensitive information.

Use like this

<form>
<input type="hidden" name="_token" value="<?= csrf_token(); ?>" />

The first thing you need to do is use the decimal type instead of float for the prices. Using float is absolutely unacceptable for that because it cannot accurately represent most decimal fractions.

Once you have done that, Decimal.Round() can be used to round to 2 places.

To start/stop the animation, you should do this:

To start:

progressBar1.Style = ProgressBarStyle.Marquee;
progressBar1.MarqueeAnimationSpeed = 30;

To stop:

progressBar1.Style = ProgressBarStyle.Continuous;
progressBar1.MarqueeAnimationSpeed = 0;

You want to do this:

<html>
<body>
<?php

print '
<script type="text/javascript">
document.write("Hello World!")
</script>
';

?>
</body>
</html>

function telephoneCheck(str) {_x000D_
  var a = /^(1\s|1|)?((\(\d{3}\))|\d{3})(\-|\s)?(\d{3})(\-|\s)?(\d{4})$/.test(str);_x000D_
  alert(a);_x000D_
}_x000D_
telephoneCheck("(555) 555-5555");

Where str could be any of these formats: 555-555-5555 (555)555-5555 (555) 555-5555 555 555 5555 5555555555 1 555 555 5555

In your Manifest you need to reference the name of the style that has the text color item inside it. Right now you are just referencing an empty style. So in your theme.xml do only this style:

<style name="Theme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
</style>

And keep you reference to in the Manifest the same (android:theme="@style/Theme")

EDIT:

theme.xml:

<style name="MyTheme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
    <item name="android:textSize">12dp</item>
</style>

Manifest:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">

Notice I combine the text color and size into the same style. Also, I changed the name of the theme to MyTheme and am now referencing that in the Manifest. And I changed to @android:style/TextAppearance for the parent value.

Clarifying it. Model:

public class ContactUsModel
{
    public string FirstName { get; set; }             
    public string LastName { get; set; }              
    public string Email { get; set; }                 
    public string Phone { get; set; }                 
    public HttpPostedFileBase attachment { get; set; }

Post Action

public virtual ActionResult ContactUs(ContactUsModel Model)
{
 if (Model.attachment.HasFile())
 {
   //save the file

   //Send it as an attachment 
    Attachment messageAttachment = new Attachment(Model.attachment.InputStream,       Model.attachment.FileName);
  }
}

Finally the Extension method for checking the hasFile

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace AtlanticCMS.Web.Common
{
     public static class ExtensionMethods 
     {
         public static bool HasFile(this HttpPostedFileBase file)
         {
             return file != null && file.ContentLength > 0;
         }        
     }
 }

You can use something like this:
note: responseText returns server response and statusText returns the predefined
message for status error.for e.g:
responseText returns something like "Not Found (#404)" in some frameworks like Yii2 but
statusText returns "Not Found".

$.ajax({
    cache: false,
    url: "addInterview_Code.asp",
    type: "POST",
    datatype: "text",
    data: strData,
    success: function (html) {
        alert('successful : ' + html);
        $("#result").html("Successful");
    },
    error: function (data) {
        console.log(data.status + ':' + data.statusText,data.responseText);
    }
});

For someone who had issues generating a single csv file from PySpark (AWS EMR) as an output and saving it on s3, using repartition helped. The reason being, coalesce cannot do a full shuffle, but repartition can. Essentially, you can increase or decrease the number of partitions using repartition, but can only decrease the number of partitions (but not 1) using coalesce. Here is the code for anyone who is trying to write a csv from AWS EMR to s3:

df.repartition(1).write.format('csv')\
.option("path", "s3a://my.bucket.name/location")\
.save(header = 'true')

You do something like this:

{{ dateObj | date:'shortDate' }}

or

{{ dateObj | date:'ddmmy' }}

See: https://angular.io/docs/ts/latest/api/common/index/DatePipe-pipe.html

In a project of our company we are using "rooms" approach and it's name is a combination of user ids of all users in a conversation as a unique identifier (our implementation is more like facebook messenger), example:

|id | name |1 | Scott |2 | Susan

"room" name will be "1-2" (ids are ordered Asc.) and on disconnect socket.io automatically cleans up the room

this way you send messages just to that room and only to online (connected) users (less packages sent throughout the server).

try {
    PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
    String versionName = packageInfo.versionName;
    int versionCode = packageInfo.versionCode;
    //binding.tvVersionCode.setText("v" + packageInfo.versionName);
}
catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}

Please use this for comparison:

string.Equals(a, b, StringComparison.CurrentCultureIgnoreCase);

using zlib.h (http://refspecs.linuxbase.org/LSB_3.0.0/LSB-Core-generic/LSB-Core-generic/zlib-crc32-1.html):

#include <zlib.h>
unsigned long  crc = crc32(0L, Z_NULL, 0);
crc = crc32(crc, (const unsigned char*)data_address, data_len);

You should specify column names as below. It's good practice and probably solve your problem

insert into abc.employees (col1,col2) 
select col1,col2 from employees where employee_id=100; 

EDIT:

As you said employees has 112 columns (sic!) try to run below select to compare both tables' columns

select * 
from ALL_TAB_COLUMNS ATC1
left join ALL_TAB_COLUMNS ATC2 on ATC1.COLUMN_NAME = ATC1.COLUMN_NAME 
                               and  ATC1.owner = UPPER('2nd owner')
where ATC1.owner = UPPER('abc')
and ATC2.COLUMN_NAME is null
AND ATC1.TABLE_NAME = 'employees'

and than you should upgrade your tables to have the same structure.

In HTML, the less-than sign is used at the beginning of tags. if you use this bracket "<test1>" in content, your bracket content will be unvisible, html renderer is assuming it as a html tag, changing chars with it's ASCI numbers prevents the issue.

with html friendly name:

  <test1> 

or with asci number:

 <test1>

or comple asci:

<test1>

result: <test1>

asci referance: https://www.w3schools.com/charsets/ref_html_ascii.asp

With my solution you're able to get something similar:

Here is bulletproff solution:

Your html: <input class='calendarIcon'/>

Your SVG: i used fa-calendar-alt

(any IDE may open svg image as shown below)

To use it at css background-image you gotta encode the svg to address valid string. I used this tool

As far as you got all stuff you need, you're coming to css

.calendarIcon{
      //your url will be something like this:
      background-image: url("data:image/svg+xml,***<here place encoded svg>***");
      background-repeat: no-repeat;
    }

Note: these styling wont have any effect on encoded svg image

.{
      fill: #f00; //neither this
      background-color: #f00; //nor this
}

because all changes over the image must be applied directly to its svg code

<svg xmlns="" path="" fill="#f00"/></svg>

To achive the location righthand i copied some Bootstrap spacing and my final css get the next look:

.calendarIcon{
      background-image: url("data:image/svg+xml,%3Csvg...svg%3E");
      background-repeat: no-repeat;
      padding-right: calc(1.5em + 0.75rem);
      background-position: center right calc(0.375em + 0.1875rem);
      background-size: calc(0.75em + 0.375rem) calc(0.75em + 0.375rem);
    }

You can use getenv function and don't have to work with a $_SERVER variable:

getenv('REQUEST_METHOD');

I was using a dialog `onError of a Video Player, and instead of going crazy (I've tested all of these solutions)

I've opted for DialogFragment http://developer.android.com/reference/android/app/DialogFragment.html.

You can return the builder creation in an inner DialogFragment class, just override onCreateDialog

declaring the list (and initializing it with an empty arraylist)

List<Card> cardList = new ArrayList<Card>();

adding an element:

Card card;
cardList.add(card);

iterating over elements:

for(Card card : cardList){
    System.out.println(card);
}

You could have multiple Python versions on your macOS.

You may check that by command, type or which command, like:

which -a python python2 python2.7 python3 python3.6

Or type python in Terminal and hit Tab few times for auto completion, which is equivalent to:

compgen -c python

By default python/pip commands points to the first binary found in PATH environment variable depending what's actually installed. So before installing Python packages with Homebrew, the default Python is installed in /usr/bin which is shipped with your macOS (e.g. Python 2.7.10 on High Sierra). Any versions found in /usr/local (such as /usr/local/bin) are provided by external packages.

It is generally advised, that when working with multiple versions, for Python 2 you may use python2/pip2 command, respectively for Python 3 you can use python3/pip3, but it depends on your configuration which commands are available.

It is also worth to mention, that since release of Homebrew 1.5.0+ (on 19 January 2018), the python formula has been upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7. Before, python formula was pointing to Python 2.

For instance, if you've installed different version via Homebrew, try the following command:

brew list python python3

or:

brew list | grep ^python

it'll show you all Python files installed with the package.

Alternatively you may use apropos or locate python command to locate more Python related files.

To check any environment variables related to Python, run:

env | grep ^PYTHON

To address your issues:

• Error: No such keg: /usr/local/Cellar/python

  Means you don't have Python installed via Homebrew. However double check by specifying only one package at a time (like brew list python python2 python3).

• The locate database (/var/db/locate.database) does not exist.

  Follow the advice and run:

  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist
  

  After the database is rebuild, you can use locate command.

Launch a program and monitor it

This form is useful if you want to benchmark an executable easily:

topp() (
  $* &>/dev/null &
  pid="$!"
  trap ':' INT
  echo 'CPU  MEM'
  while sleep 1; do ps --no-headers -o '%cpu,%mem' -p "$pid"; done
  kill "$pid"
)
topp ./myprog arg1 arg2

Now when you hit Ctrl + C it exits the program and stops monitoring. Sample output:

CPU  MEM
20.0  1.3
35.0  1.3
40.0  1.3

Tested on Ubuntu 16.04.

I think stash -p is probably the choice you want, but just in case you run into other even more tricky things in the future, remember that:

Stash is really just a very simple alternative to the only slightly more complex branch sets. Stash is very useful for moving things around quickly, but you can accomplish more complex things with branches without that much more headache and work.

# git checkout -b tmpbranch
# git add the_file
# git commit -m "stashing the_file"
# git checkout master

go about and do what you want, and then later simply rebase and/or merge the tmpbranch. It really isn't that much extra work when you need to do more careful tracking than stash will allow.

This is one of the way to add google site search to websites:

<form action="https://www.google.com/search" class="searchform" method="get" name="searchform" target="_blank">_x000D_
<input name="sitesearch" type="hidden" value="example.com">_x000D_
<input autocomplete="on" class="form-control search" name="q" placeholder="Search in example.com" required="required"  type="text">_x000D_
<button class="button" type="submit">Search</button>_x000D_
</form>

If you are using T-SQL then it appears from previous posts that UNION removes duplicates. But if you are not, you could use distinct. This doesn't quite feel right to me either but it could get you the result you are looking for

SELECT DISTINCT *
FROM
(
select * from calls
left join users a on calls.assigned_to= a.user_id
where a.dept = 4 
union
select * from calls
left join users r on calls.requestor_id= r.user_id
where r.dept = 4
)a

For a remote hosting As others have said bitbucket.org offers free private repositories, I've been using it without problems.

For local or LAN network I will add this one scm-manager.org (A single executable file, is really simple to install, it's made on Java so it can run on Linux or Windows). Just in case you install it, these are default passwords.

Here answer for your code as whole:

key =10

files = ("ME%i.txt" % i for i in range(key))

#opening
files = [ open(filename, 'w') for filename in files]

# processing
for i, file in zip(range(key),files):
    file.write(str(i))
# closing
for openfile in files:
    openfile.close()

I am using TypeScript version 3.6 and I can do like this:

let templateStr = 'This is an {0} for {1} purpose';

const finalStr = templateStr.format('example', 'format'); // This is an example for format purpose

Just export your gradient as SVG and use it using react-native-svg and when after you import your component set width and height and preserveAspectRatio="xMinYMin slice"to scale an SVG gradient at your needs.

Just to add: you also get different values for their sizes.

printf("sizeof s[] = %zu\n", sizeof(s));  //6
printf("sizeof *s  = %zu\n", sizeof(s));  //4 or 8

As mentioned above, for an array '\0' will be allocated as the final element.

Just finished understanding Peek and Keep and had same confusion initially. The confusion arises becauses TempData behaves differently under different condition. You can watch this video which explains the Keep and Peek with demonstration https://www.facebook.com/video.php?v=689393794478113

Tempdata helps to preserve values for a single request and CAN ALSO preserve values for the next request depending on 4 conditions”.

If we understand these 4 points you would see more clarity.Below is a diagram with all 4 conditions, read the third and fourth point which talks about Peek and Keep.

Condition 1 (Not read):- If you set a “TempData” inside your action and if you do not read it in your view then “TempData” will be persisted for the next request.

Condition 2 ( Normal Read) :- If you read the “TempData” normally like the below code it will not persist for the next request.

string str = TempData["MyData"];

Even if you are displaying it’s a normal read like the code below.

@TempData["MyData"];

Condition 3 (Read and Keep) :- If you read the “TempData” and call the “Keep” method it will be persisted.

@TempData["MyData"];
TempData.Keep("MyData");

Condition 4 ( Peek and Read) :- If you read “TempData” by using the “Peek” method it will persist for the next request.

string str = TempData.Peek("Td").ToString();

From the standard

7.5.2 Element identifiers: the id and class attributes

Attribute definitions

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

class = cdata-list [CS]
This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Yes, just put a space between them.

<article class="column wrapper">

Of course, there are many things you can do with CSS inheritance. Here is an article for further reading.

The CLASSPATH variable needs to include the directory where your Java programs .class file is. You can include '.' in CLASSPATH to indicate that the current directory should be included.

set CLASSPATH=%CLASSPATH%;.

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

Well 'Abstract Interface' is a Lexical construct: http://en.wikipedia.org/wiki/Lexical_analysis.

It is required by the compiler, you could also write interface.

Well don't get too much into Lexical construct of the language as they might have put it there to resolve some compilation ambiguity which is termed as special cases during compiling process or for some backward compatibility, try to focus on core Lexical construct.

The essence of `interface is to capture some abstract concept (idea/thought/higher order thinking etc) whose implementation may vary ... that is, there may be multiple implementation.

An Interface is a pure abstract data type that represents the features of the Object it is capturing or representing.

Features can be represented by space or by time. When they are represented by space (memory storage) it means that your concrete class will implement a field and method/methods that will operate on that field or by time which means that the task of implementing the feature is purely computational (requires more cpu clocks for processing) so you have a trade off between space and time for feature implementation.

If your concrete class does not implement all features it again becomes abstract because you have a implementation of your thought or idea or abstractness but it is not complete , you specify it by abstract class.

A concrete class will be a class/set of classes which will fully capture the abstractness you are trying to capture class XYZ.

So the Pattern is

Interface--->Abstract class/Abstract classes(depends)-->Concrete class

You can use some thing like this

This is your code: http://jsfiddle.net/WSFnX/

Using display: table-cell is fine, provided that you're aware that it won't work in IE6/7. Other than that, it's safe: Is there a disadvantage of using `display:table-cell`on divs?

To fix the space at the bottom, add vertical-align: bottom to the actual imgs:

http://jsfiddle.net/WSFnX/1/

Removing the space between the images boils down to this: bikeshedding CSS3 property alternative?

So, here's a demo with the whitespace removed in your HTML: http://jsfiddle.net/WSFnX/4/

Change

private ArrayList finishingOrder;

//Make an ArrayList to hold RaceCar objects to determine winners
finishingOrder = Collections.synchronizedCollection(new ArrayList(numberOfRaceCars)

to

private List finishingOrder;

//Make an ArrayList to hold RaceCar objects to determine winners
finishingOrder = Collections.synchronizedList(new ArrayList(numberOfRaceCars)

List is a supertype of ArrayList so you need to specify that.

Otherwise, what you're doing seems fine. Other option is you can use Vector, which is synchronized, but this is probably what I would do.

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Although the answer of Shane is really good, for one of my project I needed to remove the ouput messages, warnings and install packages automagically. I have finally managed to get this script:

InstalledPackage <- function(package) 
{
    available <- suppressMessages(suppressWarnings(sapply(package, require, quietly = TRUE, character.only = TRUE, warn.conflicts = FALSE)))
    missing <- package[!available]
    if (length(missing) > 0) return(FALSE)
    return(TRUE)
}

CRANChoosen <- function()
{
    return(getOption("repos")["CRAN"] != "@CRAN@")
}

UsePackage <- function(package, defaultCRANmirror = "http://cran.at.r-project.org") 
{
    if(!InstalledPackage(package))
    {
        if(!CRANChoosen())
        {       
            chooseCRANmirror()
            if(!CRANChoosen())
            {
                options(repos = c(CRAN = defaultCRANmirror))
            }
        }

        suppressMessages(suppressWarnings(install.packages(package)))
        if(!InstalledPackage(package)) return(FALSE)
    }
    return(TRUE)
}

Use:

libraries <- c("ReadImages", "ggplot2")
for(library in libraries) 
{ 
    if(!UsePackage(library))
    {
        stop("Error!", library)
    }
}

As shown in the above image, if the password is encrypted it is always a hidden secret where someone can extract the plain text password. However when password is hashed, you are relaxed as there is hardly any method of recovering the password from the hash value.

Extracted from Encrypted vs Hashed Passwords - Which is better?

Is encryption good?

Plain text passwords can be encrypted using symmetric encryption algorithms like DES, AES or with any other algorithms and be stored inside the database. At the authentication (confirming the identity with user name and password), application will decrypt the encrypted password stored in database and compare with user provided password for equality. In this type of an password handling approach, even if someone get access to database tables the passwords will not be simply reusable. However there is a bad news in this approach as well. If somehow someone obtain the cryptographic algorithm along with the key used by your application, he/she will be able to view all the user passwords stored in your database by decryption. "This is the best option I got", a software developer may scream, but is there a better way?

Cryptographic hash function (one-way-only)

Yes there is, may be you have missed the point here. Did you notice that there is no requirement to decrypt and compare? If there is one-way-only conversion approach where the password can be converted into some converted-word, but the reverse operation (generation of password from converted-word) is impossible. Now even if someone gets access to the database, there is no way that the passwords be reproduced or extracted using the converted-words. In this approach, there will be hardly anyway that some could know your users' top secret passwords; and this will protect the users using the same password across multiple applications. What algorithms can be used for this approach?

In the simplest cases type hinting should work:

$json = json_encode( (array)$object );

try this new DecimalFormat("#.00");

update:

    double angle = 20.3034;

    DecimalFormat df = new DecimalFormat("#.00");
    String angleFormated = df.format(angle);
    System.out.println(angleFormated); //output 20.30

Your code wasn't using the decimalformat correctly

The 0 in the pattern means an obligatory digit, the # means optional digit.

update 2: check bellow answer

If you want 0.2677 formatted as 0.27 you should use new DecimalFormat("0.00"); otherwise it will be .27

export const authHandler = (config) => {
  const authRegex = /^\/apiregex/;

  if (!authRegex.test(config.url)) {
    return store.fetchToken().then((token) => {
      Object.assign(config.headers.common, { Authorization: `Bearer ${token}` });
      return Promise.resolve(config);
    });
  }
  return Promise.resolve(config);
};

axios.interceptors.request.use(authHandler);

Ran into some gotchas when trying to implement something similar and based on these answers this is what I came up with. The problems I was experiencing were:

1. If using axios for the request to get a token in your store, you need to detect the path before adding the header. If you don't, it will try to add the header to that call as well and get into a circular path issue. The inverse of adding regex to detect the other calls would also work
2. If the store is returning a promise, you need to return the call to the store to resolve the promise in the authHandler function. Async/Await functionality would make this easier/more obvious
3. If the call for the auth token fails or is the call to get the token, you still want to resolve a promise with the config

The easystream open source library has direct support to convert an OutputStream to an InputStream: http://io-tools.sourceforge.net/easystream/tutorial/tutorial.html

// create conversion
final OutputStreamToInputStream<Void> out = new OutputStreamToInputStream<Void>() {
    @Override
    protected Void doRead(final InputStream in) throws Exception {
           LibraryClass2.processDataFromInputStream(in);
           return null;
        }
    };
try {   
     LibraryClass1.writeDataToTheOutputStream(out);
} finally {
     // don't miss the close (or a thread would not terminate correctly).
     out.close();
}

They also list other options: http://io-tools.sourceforge.net/easystream/outputstream_to_inputstream/implementations.html

• Write the data the data into a memory buffer (ByteArrayOutputStream) get the byteArray and read it again with a ByteArrayInputStream. This is the best approach if you're sure your data fits into memory.
• Copy your data to a temporary file and read it back.
• Use pipes: this is the best approach both for memory usage and speed (you can take full advantage of the multi-core processors) and also the standard solution offered by Sun.
• Use InputStreamFromOutputStream and OutputStreamToInputStream from the easystream library.

Late to the game.. and there are several great answers above-- essentially, that the compileSdkVersion is the version of the API the app is compiled against, while the targetSdkVersion indicates the version that the app was tested against.

I'd like to supplement those answers with the following notes:

1. That targetSdkVersion impacts the way in which permissions are requested:

• If the device is running Android 6.0 (API level 23) or higher, and the app's targetSdkVersion is 23 or higher, the app requests permissions from the user at run-time.
• If the device is running Android 5.1 (API level 22) or lower, or the app's targetSdkVersion is 22 or lower, the system asks the user to grant the permissions when the user installs the app.

2. If the compileSdkVersion is higher than the version declared by your app's targetSdkVersion, the system may enable compatibility behaviors to ensure that your app continues to work the way you expect. (ref)

3. With each new Android release...

• targetSdkVersion should be incremented to match the latest API level, then thoroughly test your application on the corresponding platform version
• compileSdkVersion, on the other hand, does not need to be changed unless you're adding features exclusive to the new platform version
• As a result, while targetSdkVersion is often (initially) less than than the compileSdkVersion, it's not uncommon to see a well-maintained/established app with targetSdkVersion > compileSdkVersion

String concatenation, str.join, can be used to build the string.

d = datetime.now()
'/'.join(str(x) for x in (d.month, d.day, d.year))
'3/7/2016'

Given two ranges [x1,x2], [y1,y2]

    return max(x1,y1) <= min(x2,y2)

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

text-align:center

Applying the text-align:center style to an element containing elements will center those elements.

<div id="method-one" style="text-align:center">
  CSS `text-align:center`
</div>

Thomas Shields mentions this method

margin:0 auto

Applying the margin:0 auto style to a block element will center it within the element it is in.

<div id="method-two" style="background-color:green">
  <div style="margin:0 auto;width:50%;background-color:lightblue">
    CSS `margin:0 auto` to have left and right margin set to center a block element within another element.
  </div>
</div>

user1468562 mentions this method

Center tag

My original answer was that you can use the <center></center> tag. To do this, just place the content you want centered between the tags. As of HTML4, this tag has been deprecated, though. <center> is still technically supported today (9 years later at the time of updating this), but I'd recommend the CSS alternatives I've included above.

<h3>Method 3</h1>
<div id="method-three">
  <center>Center tag (not recommended and deprecated in HTML4)</center>
</div>

You can see these three code samples in action in this jsfiddle.

I decided I should revise this answer as the previous one I gave was outdated. It was already deprecated when I suggested it as a solution and that's all the more reason to avoid it now 9 years later.

DWORD is not a C++ type, it's defined in <windows.h>.

The reason is that DWORD has a specific range and format Windows functions rely on, so if you require that specific range use that type. (Or as they say "When in Rome, do as the Romans do.") For you, that happens to correspond to unsigned int, but that might not always be the case. To be safe, use DWORD when a DWORD is expected, regardless of what it may actually be.

For example, if they ever changed the range or format of unsigned int they could use a different type to underly DWORD to keep the same requirements, and all code using DWORD would be none-the-wiser. (Likewise, they could decide DWORD needs to be unsigned long long, change it, and all code using DWORD would be none-the-wiser.)

Also note unsigned int does not necessary have the range 0 to 4,294,967,295. See here.

We use blat to do this all the time in our environment. I use it as well to connect to Gmail with Stunnel. Here's the params to send a file

blat -to [email protected] -server smtp.example.com -f [email protected] -subject "subject" -body "body" -attach c:\temp\file.txt

Or you can put that file in as the body

blat c:\temp\file.txt -to [email protected] -server smtp.example.com -f [email protected] -subject "subject"

int is a primitive data type while Integer is a Reference or Wrapper Type (Class) in Java.

after java 1.5 which introduce the concept of autoboxing and unboxing you can initialize both int or Integer like this.

int a= 9
Integer a = 9 // both valid After Java 1.5.

why Integer.parseInt("1"); but not int.parseInt("1"); ??

Integer is a Class defined in jdk library and parseInt() is a static method belongs to Integer Class

So, Integer.parseInt("1"); is possible in java. but int is primitive type (assume like a keyword) in java. So, you can't call parseInt() with int.

I'd like to add to bosnic's answer that any valid currency character is legal for an identifier in Java. th€is is a legal identifier, as is €this, and € as well. However, I can't figure out how to edit his or her answer, so I am forced to post this trivial addition.

If you are using grep or sed the syntax will be a little different. Notice that the sequential [^a][^b] method does not work here:

balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n'
jd8a
8$fb
q(c
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^a]$"
8$fb
q(c
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^b]$"
jd8a
q(c
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^c]$"
jd8a
8$fb
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^a][^b]$"
jd8a
q(c
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^a][^c]$"
jd8a
8$fb
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^a^b]$"
q(c
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^a^c]$"
8$fb
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^b^c]$"
jd8a
balter@spectre3:~$ printf 'jd8a\n8$fb\nq(c\n' | grep ".*[^b^c^a]$"

FWIW, I'm finding the same results in Regex101, which I think is JavaScript syntax.

I tried to send/add input tag's values into JavaScript variable which worked well for me, here is the code:

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript">
            function changef()
            {
            var ctext=document.getElementById("c").value;

            document.writeln(ctext);
            }

        </script>
    </head>
    <body>
        <input type="text" id="c" onchange="changef"();>

        <button type="button" onclick="changef()">click</button>
    </body> 
</html>

This should do the job, no?

<Button Content="Test">
    <Button.Background>
        <ImageBrush ImageSource="folder/file.PNG"/>
    </Button.Background>
</Button>

Also if you're making it a console program, you can do: print(" ") and continue your program. I've found it the easiest way to separate my text.

You could specify the dtype directly when constructing the DataFrame:

>>> df = pd.DataFrame(index=range(0,4),columns=['A'], dtype='float')
>>> df.dtypes
A    float64
dtype: object

Specifying the dtype forces Pandas to try creating the DataFrame with that type, rather than trying to infer it.

Here are a variety of ways to do this in base R including an alternative aggregate approach. The examples below return means per month, which I think is what you requested. Although, the same approach could be used to return means per person:

Using ave:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

Rate1.mean <- with(my.data, ave(Rate1, Month, FUN = function(x) mean(x, na.rm = TRUE)))
Rate2.mean <- with(my.data, ave(Rate2, Month, FUN = function(x) mean(x, na.rm = TRUE)))

my.data <- data.frame(my.data, Rate1.mean, Rate2.mean)
my.data

Using by:

my.data <- read.table(text = '
     Name     Month  Rate1     Rate2
     Aira       1      12        23
     Aira       2      18        73
     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87
     Ben        3      19        45
     Cat        1      22        87
     Cat        2      67        43
     Cat        3      45        32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')

by.month <- as.data.frame(do.call("rbind", by(my.data, my.data$Month, FUN = function(x) colMeans(x[,3:4]))))
colnames(by.month) <- c('Rate1.mean', 'Rate2.mean')
by.month <- cbind(Month = rownames(by.month), by.month)

my.data <- merge(my.data, by.month, by = 'Month')
my.data

Using lapply and split:

my.data <- read.table(text = '

     Aira       1      12        23

     Aira       3      19        45
     Ben        1      53        19
     Ben        2      22        87

ly.mean <- lapply(split(my.data, my.data$Month), function(x) c(Mean = colMeans(x[,3:4])))
ly.mean <- as.data.frame(do.call("rbind", ly.mean))
ly.mean <- cbind(Month = rownames(ly.mean), ly.mean)

my.data <- merge(my.data, ly.mean, by = 'Month')
my.data

Using sapply and split:

sy.mean <- data.frame(Month = rownames(sy.mean), sy.mean, stringsAsFactors = FALSE)
my.data <- merge(my.data, sy.mean, by = 'Month')

Using aggregate:

On Windows, search for Anaconda PowerShell Prompt. Right click the program and select Run as administrator. In the command prompt, execute the following command:

conda update -n base -c defaults conda

Your Anaconda should now update without admin related errors.

I'm going to throw my two cents into this question and suggest a slightly more verbose extension of elias's answer. As of gcc 4.6, running of gcc -march=native -v -E - < /dev/null emits an increasing amount of spam in the form of superfluous -mno-* flags. The following will strip these:

gcc -march=native -v -E - < /dev/null 2>&1 | grep cc1 | perl -pe 's/ -mno-\S+//g; s/^.* - //g;'

However, I have only verified the correctness of this on two different CPUs (an Intel Core2 and AMD Phenom), so I suggest also running the following script to be sure that all of these -mno-* flags can be safely stripped.

2021 EDIT: There are indeed machines where -march=native uses a particular -march value, but must disable some implied ISAs (Instruction Set Architecture) with -mno-*.

#!/bin/bash

gcc_cmd="gcc"

# Optionally supply path to gcc as first argument
if (($#)); then
    gcc_cmd="$1"
fi

with_mno=$(
    "${gcc_cmd}" -march=native -mtune=native -v -E - < /dev/null 2>&1 |
    grep cc1 |
    perl -pe 's/^.* - //g;'
)
without_mno=$(echo "${with_mno}" | perl -pe 's/ -mno-\S+//g;')

"${gcc_cmd}" ${with_mno}    -dM -E - < /dev/null > /tmp/gcctest.a.$$
"${gcc_cmd}" ${without_mno} -dM -E - < /dev/null > /tmp/gcctest.b.$$

if diff -u /tmp/gcctest.{a,b}.$$; then
    echo "Safe to strip -mno-* options."
else
    echo
    echo "WARNING! Some -mno-* options are needed!"
    exit 1
fi

rm /tmp/gcctest.{a,b}.$$

I haven't found a difference between gcc -march=native -v -E - < /dev/null and gcc -march=native -### -E - < /dev/null other than some parameters being quoted -- and parameters that contain no special characters, so I'm not sure under what circumstances this makes any real difference.

Finally, note that --march=native was introduced in gcc 4.2, prior to which it is just an unrecognized argument.

You could run it without the -jar command line argument if you happen to know the name of the main class you wish to run:

java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass

If perchance you are using linux, you should use ":" instead of ";" in the classpath.

Another useful property of the cross product is that its magnitude is related to the sine of the angle between the two vectors:

| a x b | = |a| . |b| . sine(theta)

or

sine(theta) = | a x b | / (|a| . |b|)

So, in implementation 1 above, if a and b are known in advance to be unit vectors then the result of that function is exactly that sine() value.

For dnf users just use dnf install *.rpm, localinstall is no longer needed.

For multiline comment in android studio

select the statement that you want to commented then

use ctrl+shift+/

and for removing mutiline comment 

select the statement that you want to uncommented then

use **ctrl+shift+/**

SINGLE LINE COMMENT

For single line comment

use ctrl+/

You can use calc to position element relative to center. For example if you want to position element 200px right from the center .. you can do this :

#your_element{
    position:absolute;
    left: calc(50% + 200px);
}

Dont forget this

When you use signs + and - you must have one blank space between sign and number, but when you use signs * and / there is no need for blank space.

you can convert to isoformat

my_date = '2020/08/08'
my_date = my_date.replace('/','-') # just to adapte to your question
date_timestamp = datetime.datetime.fromisoformat(my_date).timestamp()

You can use the --ignore-table option. So you could do

mysqldump -u USERNAME -pPASSWORD DATABASE --ignore-table=DATABASE.table1 > database.sql

There is no whitespace after -p (this is not a typo).

To ignore multiple tables, use this option multiple times, this is documented to work since at least version 5.0.

If you want an alternative way to ignore multiple tables you can use a script like this:

#!/bin/bash
PASSWORD=XXXXXX
HOST=XXXXXX
USER=XXXXXX
DATABASE=databasename
DB_FILE=dump.sql
EXCLUDED_TABLES=(
table1
table2
table3
table4
tableN   
)
 
IGNORED_TABLES_STRING=''
for TABLE in "${EXCLUDED_TABLES[@]}"
do :
   IGNORED_TABLES_STRING+=" --ignore-table=${DATABASE}.${TABLE}"
done

echo "Dump structure"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} --single-transaction --no-data --routines ${DATABASE} > ${DB_FILE}

echo "Dump content"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} ${DATABASE} --no-create-info --skip-triggers ${IGNORED_TABLES_STRING} >> ${DB_FILE}

It is a generic type constraint. In this case it means that the generic type T has to be a reference type (class, interface, delegate, or array type).

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

Many 3rd party libraries have their versions of Pair, but Java has never had such a class. The closest is the inner interface java.util.Map.Entry, which exposes an immutable key property and a possibly mutable value property.

The given solution requires enough free HDD, the actual problem was the HDD memory shortage. So If you don't have an alternative server or free disk space, you need some other alternative.

I faced this error with my production server (Linode VPS) when I was running a bulk download into MySQL. Its not a proper solution but VERY QUICK FIX, which we often need in production to bring things UP FAST.

1. Resize our VPS Server to higher Hard Disk size
2. Start MySQL, it works.
3. Login to your MySQL instance and make appropriate adjustments that caused this error (e.g. remove some records, table, or take DB backup to your local machine that are not required at production, etc. After all you know, what caused this issue.)
4. Downgrade your VPS Server to previous package you was already using

The following method worked for me. This approach allowed me to test some code that should work both in the browser and in Node.js, as it allowed me to set window to undefined.

This was with Jest 24.8 (I believe):

let windowSpy;

beforeEach(() => {
  windowSpy = jest.spyOn(window, "window", "get");
});

afterEach(() => {
  windowSpy.mockRestore();
});

it('should return https://example.com', () => {
  windowSpy.mockImplementation(() => ({
    location: {
      origin: "https://example.com"
    }
  }));

  expect(window.location.origin).toEqual("https://example.com");
});

it('should be undefined.', () => {
  windowSpy.mockImplementation(() => undefined);

  expect(window).toBeUndefined();
});

From MSDN:

Key events occur in the following order:

1. KeyDown

2. KeyPress

3. KeyUp

Furthermore, KeyPress gives you a chance to declare the action as "handled" to prevent it from doing anything.

java.util.Arrays.asList(new String[]{"a", "b"})

This seems simpler to me

<li *ngFor="let item of list | slice:0:10; let i=index" class="dropdown-item" (click)="onClick(item)">{{item.text}}</li>

Closer to your approach

<ng-container *ngFor="let item of list" let-i="index">
  <li class="dropdown-item" (click)="onClick(item)" *ngIf="i<11">{{item.text}}</li>
</ng-container>

Also with Apache StringUtils.strip():

 StringUtils.strip(null, *)          = null
 StringUtils.strip("", *)            = ""
 StringUtils.strip("abc", null)      = "abc"
 StringUtils.strip("  abc", null)    = "abc"
 StringUtils.strip("abc  ", null)    = "abc"
 StringUtils.strip(" abc ", null)    = "abc"
 StringUtils.strip("  abcyx", "xyz") = "  abc"

So,

final String SchrodingersQuotedString = "may or may not be quoted";
StringUtils.strip(SchrodingersQuotedString, "\""); //quoted no more

This method works both with quoted and unquoted strings as shown in my example. The only downside is, it will not look for strictly matched quotes, only leading and trailing quote characters (ie. no distinction between "partially and "fully" quoted strings).

If you want to try to do it by using interface, you can view my video for this. This way, you no need to write any code to show Activity Indicator in the middle of the iPhone screen.

public String removeDuplicateChar(String nonUniqueString) {
    String uniqueString = "";
    for (char currentChar : nonUniqueString.toCharArray()) {
        if (!uniqueString.contains("" + currentChar)) {
            uniqueString += currentChar;
        }
    }

    return uniqueString;
}

Building on @SotiriosDelimanolis's comment, here is a method to deal with URLs (such as file:...) and non-URLs (such as C:...), using Spring's FileSystemResource:

public FileSystemResource get(String file) {
    try {
        // First try to resolve as URL (file:...)
        Path path = Paths.get(new URL(file).toURI());
        FileSystemResource resource = new FileSystemResource(path.toFile());
        return resource;
    } catch (URISyntaxException | MalformedURLException e) {
        // If given file string isn't an URL, fall back to using a normal file 
        return new FileSystemResource(file);
    }
}

I read comments on answer set as Okay. Most of the user are asking that the button and some links click should be allowed. Here one more line is added to the existing code that will work.

<script type="text/javascript">
  var hook = true;
  window.onbeforeunload = function() {
    if (hook) {

      return "Did you save your stuff?"
    }
  }
  function unhook() {
    hook=false;
  }

Call unhook() onClick for button and links which you want to allow. E.g.

<a href="#" onClick="unhook()">This link will allow navigation</a>

Not directly an answer to your question, but you should consider naming it __version__, not version.

This is almost a quasi-standard. Many modules in the standard library use __version__, and this is also used in lots of 3rd-party modules, so it's the quasi-standard.

Usually, __version__ is a string, but sometimes it's also a float or tuple.

Edit: as mentioned by S.Lott (Thank you!), PEP 8 says it explicitly:

Module Level Dunder Names

Module level "dunders" (i.e. names with two leading and two trailing underscores) such as __all__, __author__, __version__, etc. should be placed after the module docstring but before any import statements except from __future__ imports.

You should also make sure that the version number conforms to the format described in PEP 440 (PEP 386 a previous version of this standard).

Run Xampp (apache) as administrator. In google chrome type:

localhost/<insert folder name here>/<insert file name>

i.e. if folder you created is "LearnPhp", file is "chapter1.php" then type

localhost/LearnPhp/chapter1.php

I created this folder in the xampp folder in the htdocs folder which gets created when you download xampp.

Here is a working example of extracting text from a PDF file using the current version of PDFMiner(September 2016)

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from io import StringIO

def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos=set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password,caching=caching, check_extractable=True):
        interpreter.process_page(page)

    text = retstr.getvalue()

    fp.close()
    device.close()
    retstr.close()
    return text

PDFMiner's structure changed recently, so this should work for extracting text from the PDF files.

Edit : Still working as of the June 7th of 2018. Verified in Python Version 3.x

Edit: The solution works with Python 3.7 at October 3, 2019. I used the Python library pdfminer.six, released on November 2018.

You can use the IF statement in a new cell to replace text, such as:

=IF(A4="C", "Other", A4)

This will check and see if cell value A4 is "C", and if it is, it replaces it with the text "Other"; otherwise, it uses the contents of cell A4.

EDIT

Assuming that the Employee_Count values are in B1-B10, you can use this:

=IF(B1=LARGE($B$1:$B$10, 10), "Other", B1)

This function doesn't even require the data to be sorted; the LARGE function will find the 10th largest number in the series, and then the rest of the formula will compare against that.

In my case in CPANEL i have 'Register mail ids' option where i add my email address and after 30 minutes it works fine with simple php mail function.

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

You need an additional library for code coverage, and you are going to be blown away by how powerful and easy istanbul is. Try the following, after you get your mocha tests to pass:

npm install nyc

Now, simply place the command nyc in front of your existing test command, for example:

{
  "scripts": {
    "test": "nyc mocha"
  }
}

Best way to do is use the extension(pflannery.vscode-versionlens) in vscode.

this checks for all satisfy and checks for best fit.

i had lot of issues with updating and keeping my app functioining unitll i let verbose lense did the check and then i run

npm i

to install newly suggested dependencies.

Does this not work?

System.Reflection.MethodBase.GetCurrentMethod()

Returns a MethodBase object representing the currently executing method.

I'd create a cte and do an inner join. It's not efficient but it's convenient

with table as (
SELECT DATE, STATUS, TITLE, ROW_NUMBER() 
OVER (PARTITION BY DATE, STATUS,  TITLE ORDER BY QUANTITY ASC) AS Row_Num
 FROM TABLE)

select *

from table t
join select(
max(Row_Num) as Row_Num
,DATE
,STATUS
,TITLE
from table 
group by date, status, title) t2  
on t2.Row_Num = t.Row_Num and t2
and t2.date = t.date
and t2.title = t.title

Using the examples from: https://docs.python.org/3.2/library/socketserver.html I determined that I needed to set the HOST port to the machine I had the server program running on. So TCPServer on 192.168.0.1 HOST = TCPServer IP 192.168.0.1 then I had to set the TCPClient side to point to the TCPServer IP. So the TCPClient HOST value = 192.168.0.1 - Sorry, that's the best I can describe it.

Try this:

grep "string to search for" FileNameToSearch | cut -d ":" -f 4 | sort -n | uniq -c

Sample:

grep "SMTP connect from unknown" maillog | cut -d ":" -f 4 | sort -n | uniq -c
  6  SMTP connect from unknown [188.190.118.90]
 54  SMTP connect from unknown [62.193.131.114]
  3  SMTP connect from unknown [91.222.51.253]

When comparing objects in Java, you make a semantic check, comparing the type and identifying state of the objects to:

• itself (same instance)
• itself (clone, or reconstructed copy)
• other objects of different types
• other objects of the same type
• null

Rules:

• Symmetry: a.equals(b) == b.equals(a)
• equals() always yields true or false, but never a NullpointerException, ClassCastException or any other throwable

Comparison:

• Type check: both instances need to be of the same type, meaning you have to compare the actual classes for equality. This is often not correctly implemented, when developers use instanceof for type comparison (which only works as long as there are no subclasses, and violates the symmetry rule when A extends B -> a instanceof b != b instanceof a).
• Semantic check of identifying state: Make sure you understand by which state the instances are identified. Persons may be identified by their social security number, but not by hair color (can be dyed), name (can be changed) or age (changes all the time). Only with value objects should you compare the full state (all non-transient fields), otherwise check only what identifies the instance.

For your Person class:

public boolean equals(Object obj) {

    // same instance
    if (obj == this) {
        return true;
    }
    // null
    if (obj == null) {
        return false;
    }
    // type
    if (!getClass().equals(obj.getClass())) {
        return false;
    }
    // cast and compare state
    Person other = (Person) obj;
    return Objects.equals(name, other.name) && Objects.equals(age, other.age);
}

Reusable, generic utility class:

public final class Equals {

    private Equals() {
        // private constructor, no instances allowed
    }

    /**
     * Convenience equals implementation, does the object equality, null and type checking, and comparison of the identifying state
     *
     * @param instance       object instance (where the equals() is implemented)
     * @param other          other instance to compare to
     * @param stateAccessors stateAccessors for state to compare, optional
     * @param <T>            instance type
     * @return true when equals, false otherwise
     */
    public static <T> boolean as(T instance, Object other, Function<? super T, Object>... stateAccessors) {
        if (instance == null) {
            return other == null;
        }
        if (instance == other) {
            return true;
        }
        if (other == null) {
            return false;
        }
        if (!instance.getClass().equals(other.getClass())) {
            return false;
        }
        if (stateAccessors == null) {
            return true;
        }
        return Stream.of(stateAccessors).allMatch(s -> Objects.equals(s.apply(instance), s.apply((T) other)));
    }
}

For your Person class, using this utility class:

public boolean equals(Object obj) {
    return Equals.as(this, obj, t -> t.name, t -> t.age);
}

Java doesn't support associative arrays, however this could easily be achieved using a Map. E.g.,

Map<String, String> map = new HashMap<String, String>();
map.put("name", "demo");
map.put("fname", "fdemo");
// etc

map.get("name"); // returns "demo"

Even more accurate to your example (since you can replace String with any object that meet your needs) would be to declare:

List<Map<String, String>> data = new ArrayList<>();
data.add(0, map);
data.get(0).get("name"); 

See the official documentation for more information

The simplest way to to check running processes:

ps auxwww | grep postgres

And look for a command that looks something like this (your version may not be 8.3):

/Library/PostgreSQL/8.3/bin/postgres -D /Library/PostgreSQL/8.3/data

To start the server, execute something like this:

/Library/PostgreSQL/8.3/bin/pg_ctl start -D /Library/PostgreSQL/8.3/data -l postgres.log

UseParNewGC usually knowns as "parallel young generation collector" is same in all ways as the parallel garbage collector (-XX:+UseParallelGC), except that its more sophiscated and effiecient. Also it can be used with a "concurrent low pause collector".

See Java GC FAQ, question 22 for more information.

Note that there are some known bugs with UseParNewGC

I like this question - inspired a little timer object in me:

window.setVariableInterval = function(callbackFunc, timing) {
  var variableInterval = {
    interval: timing,
    callback: callbackFunc,
    stopped: false,
    runLoop: function() {
      if (variableInterval.stopped) return;
      var result = variableInterval.callback.call(variableInterval);
      if (typeof result == 'number')
      {
        if (result === 0) return;
        variableInterval.interval = result;
      }
      variableInterval.loop();
    },
    stop: function() {
      this.stopped = true;
      window.clearTimeout(this.timeout);
    },
    start: function() {
      this.stopped = false;
      return this.loop();
    },
    loop: function() {
      this.timeout = window.setTimeout(this.runLoop, this.interval);
      return this;
    }
  };

  return variableInterval.start();
};

Example use

var vi = setVariableInterval(function() {
  // this is the variableInterval - so we can change/get the interval here:
  var interval = this.interval;

  // print it for the hell of it
  console.log(interval);

  // we can stop ourselves.
  if (interval>4000) this.stop();

  // we could return a new interval after doing something
  return interval + 100;
}, 100);  

// we can change the interval down here too
setTimeout(function() {
  vi.interval = 3500;
}, 1000);

// or tell it to start back up in a minute
setTimeout(function() {
  vi.interval = 100;
  vi.start();
}, 60000);

I use this function to indent my output (for example to print a tree structure). The indent is the number of spaces before the string.

void print_with_indent(int indent, char * string)
{
    printf("%*s%s", indent, "", string);
}

Another answer for other people who have had this problem

when you un comment the extension line, change it to:

extension=C:/php/ext/php_curl.dll

or the location of the extension folder, for me it did not work until i did this

I was looking for a more direct implementation like avijendr suggested.

I had a little trouble with his/her syntax, but I got this to work:

if ($('.user-forms input[id*="chkPrint"]:not(:checked)').length > 0)

In my case, I had a table with a class user-forms, and I was checking if any of the checkboxes that had the string checkPrint in their id were unchecked.

There is a free open source tool called Anchore that you can use to scan container images. This command will allow you to list all files in a container image

Last time I was looking for something like this I found it as an answer to this question.

File>Project Structure>Modules you can change it from there

You are always checking for a true condition, hence your message will always show.

You should replace your if (true) statement with if ( n == JOptionPane.YES_OPTION)

When one of the showXxxDialog methods returns an integer, the possible values are:

YES_OPTION NO_OPTION CANCEL_OPTION OK_OPTION CLOSED_OPTION

From here

It is 20 Minutes according to MSDN

From MSDN:

Optional TimeSpan attribute.

Specifies the number of minutes a session can be idle before it is abandoned. The timeout attribute cannot be set to a value that is greater than 525,601 minutes (1 year) for the in-process and state-server modes. The session timeout configuration setting applies only to ASP.NET pages. Changing the session timeout value does not affect the session time-out for ASP pages. Similarly, changing the session time-out for ASP pages does not affect the session time-out for ASP.NET pages. The default is 20 minutes.

You could search for the corresponding key or you could "invert" the dictionary, but considering how you use it, it would be best if you just iterated over key/value pairs in the first place, which you can do with items(). Then you have both directly in variables and don't need a lookup at all:

for key, value in PIX0.items():
    NUM = input("What is the Resolution of %s?"  % key)
    if NUM == value:

You can of course use that both ways then.

Or if you don't actually need the dictionary for something else, you could ditch the dictionary and have an ordinary list of pairs.

Google has created a library for easy Permissions management. Its called EasyPermissions

Here is a simple example on requesting Location permission using this library.

public class MainActivity extends AppCompatActivity {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requestLocationPermission();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
}

@AfterPermissionsGranted(REQUEST_CODE) is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE has been granted.

This above case, the method requestLocationPermission() method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.

You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.

p.s. REMEMBER!
dont pass EMPTY VALUES to any Directory deleting functions!!! (backup them always, otherwise one day you might get DISASTER!!)

Update 2014: C# 6 has a new operator ?. various called 'safe navigation' or 'null propagating'

parent?.child

Read http://blogs.msdn.com/b/jerrynixon/archive/2014/02/26/at-last-c-is-getting-sometimes-called-the-safe-navigation-operator.aspx for details

This has long been a hugely popular request https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/3990187-add-operator-to-c-?tracking_code=594c10a522f8e9bc987ee4a5e2c0b38d

Sorting in an ORDER BY is done by the first column, and then by each additional column in the specified statement.

For instance, consider the following data:

Column1    Column2
=======    =======
1          Smith
2          Jones
1          Anderson
3          Andrews

The query

SELECT Column1, Column2 FROM thedata ORDER BY Column1, Column2

would first sort by all of the values in Column1

and then sort the columns by Column2 to produce this:

Column1    Column2
=======    =======
1          Anderson
1          Smith
2          Jones
3          Andrews

In other words, the data is first sorted in Column1 order, and then each subset (Column1 rows that have 1 as their value) are sorted in order of the second column.

The difference between the two statements you posted is that the rows in the first one would be sorted first by prod_price (price order, from lowest to highest), and then by order of name (meaning that if two items have the same price, the one with the lower alpha value for name would be listed first), while the second would sort in name order only (meaning that prices would appear in order based on the prod_name without regard for price).

The problem is frequently with 'secure' setup of mountpoints, such as /tmp

If they are mounted noexec (check with cat /etc/mtab and or sudo mount) then there is no permission to execute any binaries or build scripts from within the (temporary) folder.

E.g. to remount temporarily:

 sudo mount -o remount,exec /tmp

Or to change permanently, remove noexec in /etc/fstab

I have same problem and I fixed this issue by following steps:

• Operating system : ubuntu 12.04
• lamp installed
• suppose your directory to save output file is : /var/www/csv/

Execute following command on terminal and edit this file using gedit editor to add your directory to output file.

sudo gedit /etc/apparmor.d/usr.sbin.mysqld

• now file would be opened in editor please add your directory there

  /var/www/csv/* rw,

• likewise I have added in my file, as following given image :

Execute next command to restart services :

sudo /etc/init.d/apparmor restart

For example I execute following query into phpmyadmin query builder to output data in csv file

SELECT colName1, colName2,colName3
INTO OUTFILE '/var/www/csv/OUTFILE.csv'
FIELDS TERMINATED BY ','
FROM tableName;

It successfully done and write all rows with selected columns into OUTPUT.csv file...

For me this has worked-

ALTER TABLE table_name ALTER COLUMN column_name VARCHAR(50)

var iframe = document.getElementById('iframeId');
var innerDoc = (iframe.contentDocument) ? iframe.contentDocument : iframe.contentWindow.document;

You could more simply write:

var iframe = document.getElementById('iframeId');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;

and the first valid inner doc will be returned.

Once you get the inner doc, you can just access its internals the same way as you would access any element on your current page. (innerDoc.getElementById...etc.)

IMPORTANT: Make sure that the iframe is on the same domain, otherwise you can't get access to its internals. That would be cross-site scripting.

Add this permission in Manifest,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

File folder = new File(Environment.getExternalStorageDirectory() + 
                             File.separator + "TollCulator");
boolean success = true;
if (!folder.exists()) {
    success = folder.mkdirs();
}
if (success) {
    // Do something on success
} else {
    // Do something else on failure 
}

when u run the application go too DDMS->File Explorer->mnt folder->sdcard folder->toll-creation folder

For more better result the best way is to append the GUID with the timestamp (Just to make sure that it stays unique)

Guid.NewGuid().ToString() + DateTime.Now.ToString();

With base graphics, the easiest way is to stop the plotting functions from drawing axes and then draw them yourself.

plot(1:10, 1:10, axes = FALSE)
axis(side = 1, at = c(1,5,10))
axis(side = 2, at = c(1,3,7,10))
box()

Your code concatenates three strings, then converts the result to a number.

You need to convert each variable to a number by calling parseFloat() around each one.

total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);

If you can pick a reasonable maximum line length, you can seek to nearly the end of the file before you start reading.

myfile.seek(-max_line_length, os.SEEK_END)
line = myfile.readlines()[-1]

The <Comment> tag contains two text nodes and two <br> nodes as children.

Your xpath expression was

//*[contains(text(),'ABC')]

To break this down,

1. * is a selector that matches any element (i.e. tag) -- it returns a node-set.
2. The [] are a conditional that operates on each individual node in that node set. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
3. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
4. contains is a function that operates on a string. If it is passed a node set, the node set is converted into a string by returning the string-value of the node in the node-set that is first in document order. Hence, it can match only the first text node in your <Comment> element -- namely BLAH BLAH BLAH. Since that doesn't match, you don't get a <Comment> in your results.

You need to change this to

//*[text()[contains(.,'ABC')]]

1. * is a selector that matches any element (i.e. tag) -- it returns a node-set.
2. The outer [] are a conditional that operates on each individual node in that node set -- here it operates on each element in the document.
3. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
4. The inner [] are a conditional that operates on each node in that node set -- here each individual text node. Each individual text node is the starting point for any path in the brackets, and can also be referred to explicitly as . within the brackets. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
5. contains is a function that operates on a string. Here it is passed an individual text node (.). Since it is passed the second text node in the <Comment> tag individually, it will see the 'ABC' string and be able to match it.

Well, I believe that I've solved the password configuration 'issue' - WampServer 2.2 - Windows 7.

The three steps that I did:

1. In the MySQL console set a new password. To make that: mysqladmin -u root password 'your_password'

2. In phpMyAdmin click in users and set the same password to the user root.

3. Finally, set your new password in the config.inc.php. Don't change anything else in this file.

This worked for me. Good luck!

How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it?

I posted a gist that solves this question/problem with a decorator and a threading.Timer. Here it is with a breakdown.

Imports and setups for compatibility

It was tested with Python 2 and 3. It should also work under Unix/Linux and Windows.

First the imports. These attempt to keep the code consistent regardless of the Python version:

from __future__ import print_function
import sys
import threading
from time import sleep
try:
    import thread
except ImportError:
    import _thread as thread

Use version independent code:

try:
    range, _print = xrange, print
    def print(*args, **kwargs): 
        flush = kwargs.pop('flush', False)
        _print(*args, **kwargs)
        if flush:
            kwargs.get('file', sys.stdout).flush()            
except NameError:
    pass

Now we have imported our functionality from the standard library.

exit_after decorator

Next we need a function to terminate the main() from the child thread:

def quit_function(fn_name):
    # print to stderr, unbuffered in Python 2.
    print('{0} took too long'.format(fn_name), file=sys.stderr)
    sys.stderr.flush() # Python 3 stderr is likely buffered.
    thread.interrupt_main() # raises KeyboardInterrupt

And here is the decorator itself:

def exit_after(s):
    '''
    use as decorator to exit process if 
    function takes longer than s seconds
    '''
    def outer(fn):
        def inner(*args, **kwargs):
            timer = threading.Timer(s, quit_function, args=[fn.__name__])
            timer.start()
            try:
                result = fn(*args, **kwargs)
            finally:
                timer.cancel()
            return result
        return inner
    return outer

Usage

And here's the usage that directly answers your question about exiting after 5 seconds!:

@exit_after(5)
def countdown(n):
    print('countdown started', flush=True)
    for i in range(n, -1, -1):
        print(i, end=', ', flush=True)
        sleep(1)
    print('countdown finished')

Demo:

>>> countdown(3)
countdown started
3, 2, 1, 0, countdown finished
>>> countdown(10)
countdown started
10, 9, 8, 7, 6, countdown took too long
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 11, in inner
  File "<stdin>", line 6, in countdown
KeyboardInterrupt

The second function call will not finish, instead the process should exit with a traceback!

KeyboardInterrupt does not always stop a sleeping thread

Note that sleep will not always be interrupted by a keyboard interrupt, on Python 2 on Windows, e.g.:

@exit_after(1)
def sleep10():
    sleep(10)
    print('slept 10 seconds')

>>> sleep10()
sleep10 took too long         # Note that it hangs here about 9 more seconds
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 11, in inner
  File "<stdin>", line 3, in sleep10
KeyboardInterrupt

nor is it likely to interrupt code running in extensions unless it explicitly checks for PyErr_CheckSignals(), see Cython, Python and KeyboardInterrupt ignored

I would avoid sleeping a thread more than a second, in any case - that's an eon in processor time.

How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it and does something else?

To catch it and do something else, you can catch the KeyboardInterrupt.

>>> try:
...     countdown(10)
... except KeyboardInterrupt:
...     print('do something else')
... 
countdown started
10, 9, 8, 7, 6, countdown took too long
do something else

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

<EditText
    android:id="@+id/search"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search_hint"
    android:inputType="text"
    android:imeOptions="actionSend" />

You can then listen for presses on the action button by defining a TextView.OnEditorActionListener for the EditText element. In your listener, respond to the appropriate IME action ID defined in the EditorInfo class, such as IME_ACTION_SEND. For example:

EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean handled = false;
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            sendMessage();
            handled = true;
        }
        return handled;
    }
});

Search for [ ]{2,}. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.

Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).

The problem with \s{2,} is that it will also match newlines on Windows files (where newlines are denoted by CRLF or \r\n which is matched by \s{2}.

If you also want to find multiple tabs and spaces, use [ \t]{2,}.

I figured it out! The page was rendering using IE8 mode... had

<meta http-equiv="X-UA-Compatible" content="IE=8">

in the header... changed it to

<meta http-equiv="X-UA-Compatible" content="IE=9">

9 and it worked!

i think a text view is not focusable. Try to set the focus on a button for example, or to set the property focusable to true.

First, to address your first inquiry:

When you see this in .h file:

#ifndef FILE_H
#define FILE_H

/* ... Declarations etc here ... */

#endif

This is a preprocessor technique of preventing a header file from being included multiple times, which can be problematic for various reasons. During compilation of your project, each .cpp file (usually) is compiled. In simple terms, this means the compiler will take your .cpp file, open any files #included by it, concatenate them all into one massive text file, and then perform syntax analysis and finally it will convert it to some intermediate code, optimize/perform other tasks, and finally generate the assembly output for the target architecture. Because of this, if a file is #included multiple times under one .cpp file, the compiler will append its file contents twice, so if there are definitions within that file, you will get a compiler error telling you that you redefined a variable. When the file is processed by the preprocessor step in the compilation process, the first time its contents are reached the first two lines will check if FILE_H has been defined for the preprocessor. If not, it will define FILE_H and continue processing the code between it and the #endif directive. The next time that file's contents are seen by the preprocessor, the check against FILE_H will be false, so it will immediately scan down to the #endif and continue after it. This prevents redefinition errors.

And to address your second concern:

In C++ programming as a general practice we separate development into two file types. One is with an extension of .h and we call this a "header file." They usually provide a declaration of functions, classes, structs, global variables, typedefs, preprocessing macros and definitions, etc. Basically, they just provide you with information about your code. Then we have the .cpp extension which we call a "code file." This will provide definitions for those functions, class members, any struct members that need definitions, global variables, etc. So the .h file declares code, and the .cpp file implements that declaration. For this reason, we generally during compilation compile each .cpp file into an object and then link those objects (because you almost never see one .cpp file include another .cpp file).

How these externals are resolved is a job for the linker. When your compiler processes main.cpp, it gets declarations for the code in class.cpp by including class.h. It only needs to know what these functions or variables look like (which is what a declaration gives you). So it compiles your main.cpp file into some object file (call it main.obj). Similarly, class.cpp is compiled into a class.obj file. To produce the final executable, a linker is invoked to link those two object files together. For any unresolved external variables or functions, the compiler will place a stub where the access happens. The linker will then take this stub and look for the code or variable in another listed object file, and if it's found, it combines the code from the two object files into an output file and replaces the stub with the final location of the function or variable. This way, your code in main.cpp can call functions and use variables in class.cpp IF AND ONLY IF THEY ARE DECLARED IN class.h.

I hope this was helpful.

You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

You just need to add a jquery selector after the url.

See: http://api.jquery.com/load/

Example straight from the API:

$('#result').load('ajax/test.html #container');

So what that does is it loads the #container element from the specified url.

Another easy way to do this.

step 1) create a layout with proper id's.

step 2) use the following code wherever you desire.

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

For validation I ran the benchmark code provided by @Cron. There is one major difference (in addition to running faster on the newer i7 processor): the by_index now performs nearly as well as the list_:

              expr        min         lq       mean     median         uq

For reference here is the benchmark code copied verbatim from @Cron's answer (just in case he later changes the contents):

n = 1e+4
library(microbenchmark)
### Using environment as a container
lPtrAppend <- function(lstptr, lab, obj) {lstptr[[deparse(substitute(lab))]] <- obj}
### Store list inside new environment
envAppendList <- function(lstptr, obj) {lstptr$list[[length(lstptr$list)+1]] <- obj}

microbenchmark(times = 5,
        env_with_list_ = {
            listptr <- new.env(parent=globalenv())
            listptr$list <- NULL
            for(i in 1:n) {envAppendList(listptr, i)}
            listptr$list
        },
        c_ = {
            a <- list(0)
            for(i in 1:n) {a = c(a, list(i))}
        },
        list_ = {
            a <- list(0)
            for(i in 1:n) {a <- list(a, list(i))}
        },
        by_index = {
            a <- list(0)
            for(i in 1:n) {a[length(a) + 1] <- i}
            a
        },
        append_ = {
            a <- list(0)
            for(i in 1:n) {a <- append(a, i)}
            a
        },
        env_as_container_ = {
            listptr <- new.env(parent=globalenv())
            for(i in 1:n) {lPtrAppend(listptr, i, i)}
            listptr
        }
)

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

add this line in your css file:

.classname ul li {
    float: left;
}

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

This is how you can set the timeout after you click.

$(".selectorOnWhichEventCapture").on('click', function() {
    setTimeout(function(){
        $(".selector").doWhateverYouWantToDo();
    }, 5000);
});

//5000 = 5sec = 5000 milisec

For Eclipse plugins, you just unzip them and drop the folder in the Eclipse\Plugins directory. Simple as that.

Sliding the space bar only works if you gave more then one input language selected.

In that case the space bar will also indicate the selected language and show arrows to indicate Sliding will change selection.

This is easy fast and changes the dictionary at the same time.

First response seems the mist accurate.

Don't use systemPath. Contrary to what people have said here, you can put an external jar in a folder under your checked-out project directory and haven Maven find it like other dependencies. Here are two crucial steps:

1. Use "mvn install:install-file" with -DlocalRepositoryPath.
2. Configure a repository to point to that path in your POM.

It is fairly straightforward and you can find a step-by-step example here: http://randomizedsort.blogspot.com/2011/10/configuring-maven-to-use-local-library.html

\begin{tikzpicture}

    \tikzstyle{every node}=[font=\small]

\end{tikzpicture}

will give you font size control on every node.

You can use the Linux based syntax in one of your startup scripts. Just tested this on an OS X Mountain Lion box.

eg. in your ~/.bash_profile

export TERM="xterm-color" 
export PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

This gives you a nice colored prompt. To add the colored ls output, you can add alias ls="ls -G".

To test, just run a source ~/.bash_profile to update your current terminal.

Side note about the colors: The colors are preceded by an escape sequence \e and defined by a color value, composed of [style;color+m] and wrapped in an escaped [] sequence. eg.

• red = \[\e[0;31m\]
• bold red (style 1) = \[\e[1;31m\]
• clear coloring = \[\e[0m\]

I always add a slightly modified color-scheme in the root's .bash_profile to make the username red, so I always see clearly if I'm logged in as root (handy to avoid mistakes if I have many terminal windows open).

In /root/.bash_profile:

PS1='\[\e[0;31m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

For all my SSH accounts online I make sure to put the hostname in red, to distinguish if I'm in a local or remote terminal. Just edit the .bash_profile file in your home dir on the server.. If there is no .bash_profile file on the server, you can create it and it should be sourced upon login.

If this is not working as expected for you, please read some of the comments below since I'm not using MacOS very often..

If you want to do this on a remote server, check if the ~/.bash_profile file exists. If not, simply create it and it should be automatically sourced upon your next login.

I found the best solution after many attempts for this problem.

Use org.apache.commons.lang3.StringUtils

String emptyString = new String();    
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);

String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);

Both of the above options will print:
