The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

I find that solution more elegant:

for (let val in myEnum ) {

 if ( isNaN( parseInt( val )) )
     console.log( val );
}

It displays:

bar 
foo

Nav.js comp inside components folder

export {Nav}

index.js in component folder

export {Nav} from './Nav';
export {Another} from './Another';

import anywhere

import {Nav, Another} from './components'

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

Use

.remove() of Interator or

Use

CopyOnWriteArrayList

I was able to solve this one by following the steps listed here:http://forum.xda-developers.com/showthread.php?t=2247471

delete the computers adb key: rm /data/misc/adb/adb_key on device 

(I have no idea if in case of multiple authorized computers the additional keys are in a new line of the file or if they are in new files. I have only 1 computer.)

stop all adb processes "killall adb" in linuxoids and "taskkill /IM adb.exe" in windows or simply the taskmanager in both.

restart the phone

toggle usb debugging off and on

connect

use adb

click authorize

just simply use as below and it will word wrap any long text within a table . No need to anything else

<td style="word-wrap: break-word;min-width: 160px;max-width: 160px;">long long comments</td>

I found this: https://github.com/PHPGangsta/GoogleAuthenticator. I tested it and works fine for me.

For those who are using Visual Studio 2017 version, it seems like the preprocessor definition required to run unsafe operations has changed. Use instead:

#define _CRT_SECURE_NO_WARNINGS

It will compile then.

A simple, straightforward (non-regex) solution:

const capitalizeFirstLetter = s => 
  s.split(' ').map(w => w.charAt(0).toUpperCase() + w.slice(1)).join(' ')

1. Break the string into words Array (by space delimiter)
2. Break each word to first character + rest of characters in the word
3. The first letter is transformed to uppercase, and the rest remains as-is
4. Joins back the Array into a string with spaces

The HTML5 fileReader facility does allow you to process local files, but these MUST be selected by the user, you cannot go rooting about the users disk looking for files.

I currently use this with development versions of Chrome (6.x). I don't know what other browsers support it.

On Linux this will paste text directly from the clipboard

adb shell input text "'$(xclip -selection c -o)'"

Also it very useful to create global keyboard shortkey with this command for example Ctrl+Shift+Super+V

The job of the DispatcherServlet is to take an incoming URI and find the right combination of handlers (generally methods on Controller classes) and views (generally JSPs) that combine to form the page or resource that's supposed to be found at that location.

I might have

• a file /WEB-INF/jsp/pages/Home.jsp

• and a method on a class

  @RequestMapping(value="/pages/Home.html")
  private ModelMap buildHome() {
      return somestuff;
  }
  

The Dispatcher servlet is the bit that "knows" to call that method when a browser requests the page, and to combine its results with the matching JSP file to make an html document.

How it accomplishes this varies widely with configuration and Spring version.

There's also no reason the end result has to be web pages. It can do the same thing to locate RMI end points, handle SOAP requests, anything that can come into a servlet.

Remember to check firewall settings as well. after checking and double-checking my pg_hba.conf and postgres.conf files I finally found out that my firewall was overriding everything and therefore blocking connections

A simple way to achieve what you want:

import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img

Update

I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:

s_img = cv2.imread("smaller_image.png", -1)

y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]

alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s

for c in range(0, 3):
    l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
                              alpha_l * l_img[y1:y2, x1:x2, c])

I think this is enough to get you on a nice path:

Sub a()
  Dim btn As Button
  Application.ScreenUpdating = False
  ActiveSheet.Buttons.Delete
  Dim t As Range
  For i = 2 To 6 Step 2
    Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
    Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
    With btn
      .OnAction = "btnS"
      .Caption = "Btn " & i
      .Name = "Btn" & i
    End With
  Next i
  Application.ScreenUpdating = True
End Sub

Sub btnS()
 MsgBox Application.Caller
End Sub

It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.

You can use std::find as follows:

if (std::find(v.begin(), v.end(), "abc") != v.end())
{
  // Element in vector.
}

To be able to use std::find: include <algorithm>.

U can try this :-

    wget -q -O - http://www.example.com/ >/dev/null 2>&1

What you have seems to be a string incorrectly decoded from another encoding, likely code page 1252, which is US Windows default. Here's how to reverse, assuming no other loss. One loss not immediately apparent is the non-breaking space (U+00A0) at the end of your string that is not displayed. Of course it would be better to read the data source correctly in the first place, but perhaps the data source was stored incorrectly to begin with.

using System;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        string junk = "déjÃ\xa0";  // Bad Unicode string

        // Turn string back to bytes using the original, incorrect encoding.
        byte[] bytes = Encoding.GetEncoding(1252).GetBytes(junk);

        // Use the correct encoding this time to convert back to a string.
        string good = Encoding.UTF8.GetString(bytes);
        Console.WriteLine(good);
    }
}

Result:

I found simple solution, which works fine even if you want add new fragments in the middle or replace current fragment. In my solution you should override getItemId() which should return unique id for each fragment. Not position as by default.

There is it:

public class DynamicPagerAdapter extends FragmentPagerAdapter {

private ArrayList<Page> mPages = new ArrayList<Page>();
private ArrayList<Fragment> mFragments = new ArrayList<Fragment>();

public DynamicPagerAdapter(FragmentManager fm) {
    super(fm);
}

public void replacePage(int position, Page page) {
    mPages.set(position, page);
    notifyDataSetChanged();
}

public void setPages(ArrayList<Page> pages) {
    mPages = pages;
    notifyDataSetChanged();
}

@Override
public Fragment getItem(int position) {
    if (mPages.get(position).mPageType == PageType.FIRST) {
        return FirstFragment.newInstance(mPages.get(position));
    } else {
        return SecondFragment.newInstance(mPages.get(position));
    }
}

@Override
public int getCount() {
    return mPages.size();
}

@Override
public long getItemId(int position) {
    // return unique id
    return mPages.get(position).getId();
}

@Override
public Object instantiateItem(ViewGroup container, int position) {
    Fragment fragment = (Fragment) super.instantiateItem(container, position);
    while (mFragments.size() <= position) {
        mFragments.add(null);
    }
    mFragments.set(position, fragment);
    return fragment;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    super.destroyItem(container, position, object);
    mFragments.set(position, null);
}

@Override
public int getItemPosition(Object object) {
    PagerFragment pagerFragment = (PagerFragment) object;
    Page page = pagerFragment.getPage();
    int position = mFragments.indexOf(pagerFragment);
    if (page.equals(mPages.get(position))) {
        return POSITION_UNCHANGED;
    } else {
        return POSITION_NONE;
    }
}
}

Notice: In this example FirstFragment and SecondFragment extends abstract class PageFragment, which has method getPage().

Your form is valid. Only thing that comes to my mind is, after seeing your full html, is that you're passing your "default" value (which is not set!) instead of selecting something. Try as suggested by @Vina in the comment, i.e. giving it a selected option, or writing a default value

<select name="gender">
<option value="default">Select </option>    
<option value="male">   Male   </option>
<option value="female"> Female </option>
</select>

OR

<select name="gender">
<option value="male" selected="selected">   Male   </option>
<option value="female"> Female </option>
</select>

When you get your $_POST vars, check for them being set; you can assign a default value, or just an empty string in case they're not there.

Most important thing, AVOID SQL INJECTIONS:

//....
$fname   = isset($_POST["fname"]) ? mysql_real_escape_string($_POST['fname']) : '';
$lname   = isset($_POST['lname']) ? mysql_real_escape_string($_POST['lname']) : '';
$email   = isset($_POST['email']) ? mysql_real_escape_string($_POST['email']) : '';
you might also want to validate e-mail:
if($mail = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
{
  $email = mysql_real_escape_string($_POST['email']);
}
else
{
  //die ('invalid email address');
  // or whatever, a default value? $email = '';
}
$paswod  = isset($_POST["paswod"]) ? mysql_real_escape_string($_POST['paswod']) : '';
$gender  = isset($_POST['gender']) ? mysql_real_escape_string($_POST['gender']) : '';

$query = mysql_query("SELECT Email FROM users WHERE Email = '".$email."')";
if(mysql_num_rows($query)> 0)
{
  echo 'userid is already there';
}
else
{
 $sql = "INSERT INTO users (FirstName, LastName, Email, Password, Gender)
         VALUES ('".$fname."','".$lname."','".$email."','".paswod."','".$gender."')";
$res = mysql_query($sql) or die('Error:'.mysql_error());
echo 'created';

I had this problem when I used Maven 3.5.4 on OpenJDK 11 on Ubuntu. The OpenJDK 11 on Ubuntu is actually still a JDK10:

$ ls -al /etc/alternatives/java
lrwxrwxrwx 1 root root 43 Aug 24 04:54 /etc/alternatives/java -> /usr/lib/jvm/java-11-openjdk-amd64/bin/java
$ java --version
openjdk 10.0.2 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.3)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.3, mixed mode)

I installed OpenJDK from Oracle into /opt/jdk-11.0.1 and run Maven like this:

JAVA_HOME=/opt/jdk-11.0.1 mvn

It now works like a charm.

Here's a solution for find/replace in all files of a given directory. Basically I took the answer provided by sepp2k and expanded it.

# First set the files to search/replace in
files = Dir.glob("/PATH/*")

# Then set the variables for find/replace
@original_string_or_regex = /REGEX/
@replacement_string = "STRING"

files.each do |file_name|
  text = File.read(file_name)
  replace = text.gsub!(@original_string_or_regex, @replacement_string)
  File.open(file_name, "w") { |file| file.puts replace }
end

A dplyr solution:

Idea:

• add rowids as a column
• reshape to long format
• filter for max in each group

Code:

DF = data.frame(V1=c(2,8,1),V2=c(7,3,5),V3=c(9,6,4))
DF %>% 
  rownames_to_column() %>%
  gather(column, value, -rowname) %>%
  group_by(rowname) %>% 
  filter(rank(-value) == 1) 

Result:

# A tibble: 3 x 3
# Groups:   rowname [3]
  rowname column value
  <chr>   <chr>  <dbl>
1 2       V1         8
2 3       V2         5
3 1       V3         9

This approach can be easily extended to get the top n columns. Example for n=2:

DF %>% 
  rownames_to_column() %>%
  gather(column, value, -rowname) %>%
  group_by(rowname) %>% 
  mutate(rk = rank(-value)) %>%
  filter(rk <= 2) %>% 
  arrange(rowname, rk) 

Result:

# A tibble: 6 x 4
# Groups:   rowname [3]
  rowname column value    rk
  <chr>   <chr>  <dbl> <dbl>
1 1       V3         9     1
2 1       V2         7     2
3 2       V1         8     1
4 2       V3         6     2
5 3       V2         5     1
6 3       V3         4     2

Base on @Mark answer, I add the constructor to directive and it work with me.

I share a sample to whom concern.

constructor(private el: ElementRef, private renderer: Renderer) {
}

TS file

@Directive({ selector: '[accordion]' })
export class AccordionDirective {

  constructor(private el: ElementRef, private renderer: Renderer) {
  }

  @HostListener('click', ['$event']) onClick($event) {
    console.info($event);

    this.el.nativeElement.classList.toggle('is-open');

    var content = this.el.nativeElement.nextElementSibling;
    if (content.style.maxHeight) {
      // accordion is currently open, so close it
      content.style.maxHeight = null;
    } else {
      // accordion is currently closed, so open it
      content.style.maxHeight = content.scrollHeight + "px";

    }
  }
}

HTML

<button accordion class="accordion">Accordian #1</button>
    <div class="accordion-content">
      <p>

To install the latest stable version:

nvm install stable

To set default to the stable version (instead of a specific version):

nvm alias default stable

To list installed versions:

nvm list

As of v6.2.0, it will look something like:

$ nvm list
         v4.4.2
->       v6.2.0
default -> stable (-> v6.2.0)
node -> stable (-> v6.2.0) (default)
stable -> 6.2 (-> v6.2.0) (default)
iojs -> N/A (default)

instead of trying & catching expressions.. its better to run regex on the string to ensure that it is a valid number..

My function will check if the user has selected the file or not and you can also check whether you want to allow that file extension or not.

Try this:

<input type="file" name="fileUpload" onchange="validate_fileupload(this.value);">

function validate_fileupload(fileName)
{
    var allowed_extensions = new Array("jpg","png","gif");
    var file_extension = fileName.split('.').pop().toLowerCase(); // split function will split the filename by dot(.), and pop function will pop the last element from the array which will give you the extension as well. If there will be no extension then it will return the filename.

    for(var i = 0; i <= allowed_extensions.length; i++)
    {
        if(allowed_extensions[i]==file_extension)
        {
            return true; // valid file extension
        }
    }

    return false;
}

cat .ssh/id_rsa.pub | bcopy

This works for me.

Open modal windows with passing data to dialog

In case if someone interests to pass data to dialog:

app.controller('ModalCtrl', function($scope,  $modal) {
      
      $scope.name = 'theNameHasBeenPassed';

      $scope.showModal = function() {
        
        $scope.opts = {
        backdrop: true,
        backdropClick: true,
        dialogFade: false,
        keyboard: true,
        templateUrl : 'modalContent.html',
        controller : ModalInstanceCtrl,
        resolve: {} // empty storage
          };
          
        
        $scope.opts.resolve.item = function() {
            return angular.copy(
                                {name: $scope.name}
                          ); // pass name to resolve storage
        }
        
          var modalInstance = $modal.open($scope.opts);
          
          modalInstance.result.then(function(){
            //on ok button press 
          },function(){
            //on cancel button press
            console.log("Modal Closed");
          });
      };                   
})

var ModalInstanceCtrl = function($scope, $modalInstance, $modal, item) {
    
     $scope.item = item;
    
      $scope.ok = function () {
        $modalInstance.close();
      };
      
      $scope.cancel = function () {
        $modalInstance.dismiss('cancel');
      };
}

Demo Plunker

This is the way how I will debug:

CREATE PROCEDURE procedure_name() 
BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION
    BEGIN
        SHOW ERRORS;  --this is the only one which you need
        ROLLBACK;   
    END; 
    START TRANSACTION;
        --query 1
        --query 2
        --query 3
    COMMIT;
END 

If query 1, 2 or 3 will throw an error, HANDLER will catch the SQLEXCEPTION and SHOW ERRORS will show errors for us. Note: SHOW ERRORS should be the first statement in the HANDLER.

Download the html page and use find()

You can use the HTML tag in order to apply font size, font color in one line on JavaScript, as well as you can use .fontcolor() method to define color, .fontsize() method to define the font size, .bold() method to define bold, etc. These are called JavaScript Built-in Functions.

• Here is a list of some JavaScript built-in functions:

  .big()
  .small()
  .italics()
  .fixed()
  .strike()
  .sup()

• The below built-in functions require parameters:

  .fontsize() //e.g.: the size to be applied in number .fontsize(4)

  .fontcolor("") //e.g.: the color to be applied in string .fontcolor("red")

  .txt.link("") //e.g.: the url to be linkable as string .link("www.test.com")

  .toUpperCase() //e.g.: the converted to uppercase to be applied in string .toUpperCase()

• Remember the syntax is: string.functionName() e.g.:

  var txt = "Hello World!"; txt.bold();

• This also can be done in one line:

  var txt = "Hello World!".bold();

  The result will be: Hello World!

• You can use multiple built-in functions in one line, adding one next to the other. e.g.:

  "10/22/2018".fontcolor("red").fontsize(4).bold()

• The following is an example how I used it on my JavaScript code to change font (color, size, bold) using both HTML tags and JavaScript functions:

vForm.message = "<HTML><font size = 4 color = 'red'><b> Application Deadline was </b></font></HTML> " + "10/22/2018".fontcolor("red").fontsize(4).bold(); /* setting HTML font color, size, bold and combined them with JavaScript functions to change font color, size, bold in JavaScript code */

• Here is the result:

possibly if you want to just transfer data to be used by JavaScript then you can use Hash Tags like this

http://localhost/project/index.html#exist

so once when you are done retriving the data show the message and change the window.location.hash to a suitable value.. now whenever you ll refresh the page the hashtag wont be present
NOTE: when you will use this instead ot query strings the data being sent cannot be retrived/read by the server

The formula provided by Blake doesn't seem to work for me. For past dates it returns due in xx days and for future dates, it returns overdue. Also, it will only return 15 days overdue, when it could actually be 30, 60 90+.

I created this, which seems to work and provides 'Due in xx days', 'Overdue xx days' and 'Due Today'.

=IF(ISBLANK(O10),"",IF(DAYS(TODAY(),O10)<0,CONCATENATE("Due in ",-DAYS(TODAY(),O10)," Days"),IF(DAYS(TODAY(),O10)>0,CONCATENATE("Overdue ",DAYS(TODAY(),O10)," Days"),"Due Today")))

Guava library

We have a Guava class for this: com.google.common.net.MediaType.

It was released with Guava 12 as stated in the source code and in Issue 823. Sources are available, too.

If [John Smith] is in cell A1, then use this formula to do what you want:

=SUBSTITUTE(SUBSTITUTE(A1, "[", ""), "]", "")

The inner SUBSTITUTE replaces all instances of "[" with "" and returns a new string, then the other SUBSTITUTE replaces all instances of "]" with "" and returns the final result.

You will need some JavaScript to prevent cropping if you don't know the dimension of the image at the time you're writing the css.

HTML & JavaScript

<div id="container">
    <img src="something.jpg" alt="" />
</div>

<script type="text/javascript">
(function() {

var img = document.getElementById('container').firstChild;
img.onload = function() {
    if(img.height > img.width) {
        img.height = '100%';
        img.width = 'auto';
    }
};

}());
</script>

CSS

#container {
   width: 48px;
   height: 48px;
}

#container img {
   width: 100%;
}

If you use a JavaScript Library you might want to take advantage of it.

The best practice is to check the Identity.IsAuthenticated Property first and then get the usr.UserName like this:

string userName = string.Empty;

if (System.Web.HttpContext.Current != null && 
    System.Web.HttpContext.Current.User.Identity.IsAuthenticated)
{
    System.Web.Security.MembershipUser usr = Membership.GetUser();
    if (usr != null)
    {  
        userName = usr.UserName;
    }
}

In my case it was resolved by changing the compileSdkVersion and targetSdkVersion from 26 to 27

A rather roundabout way, just for completeness:

 for /f "delims=" %i in ('type CON') do set inp=%i

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

Edit: In Swift 3:

let indexPath = IndexPath(row: rowIndex, section: sectionIndex)

Swift 5

IndexPath(row: 0, section: 0)

One alternative would be to use a getter/setter methods.

For instance, if you only care about reading the calculated value:

var book  = {}

Object.defineProperties(book,{
    key1: { value: "it", enumerable: true },
    key2: {
        enumerable: true,
        get: function(){
            return this.key1 + " works!";
        }
    }
});

console.log(book.key2); //prints "it works!"

The above code, though, won't let you define another value for key2.

So, the things become a bit more complicated if you would like to also redefine the value of key2. It will always be a calculated value. Most likely that's what you want.

However, if you would like to be able to redefine the value of key2, then you will need a place to cache its value independently of the calculation.

Somewhat like this:

var book  = { _key2: " works!" }

Object.defineProperties(book,{
    key1: { value: "it", enumerable: true},
    _key2: { enumerable: false},
    key2: {
        enumerable: true,
        get: function(){
            return this.key1 + this._key2;
        },
        set: function(newValue){
            this._key2 = newValue;
        }
    }
});

console.log(book.key2); //it works!

book.key2 = " doesn't work!";
console.log(book.key2); //it doesn't work!

for(var key in book){
    //prints both key1 and key2, but not _key2
    console.log(key + ":" + book[key]); 
}

Another interesting alternative is to use a self-initializing object:

var obj = ({

As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )

The querystring (get) parameters included in your url probably will not do anything.

Try this:

string url = "http://myserver/method";    
string content = "param1=1&param2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

This is old and my problem ended up being related to the problem but not for the OP but my solution is for anyone else who tried the above to no avail.

I had a setting in a modified version of Django to minify CSS and JS files that only ran when DEBUG was off. My server did not have the CSS minifier installed and threw the error. If you are using Django-Mako-Plus, this might be your issue.

Below Kotlin code will help

Bottom to Top or Slide to Up

private fun slideUp() {
    isMapInfoShown = true
    views!!.layoutMapInfo.visible()
    val animate = TranslateAnimation(
        0f,  // fromXDelta
        0f,  // toXDelta
        views!!.layoutMapInfo.height.toFloat(),  // fromYDelta
        0f  // toYDelta
    )

    animate.duration = 500
    animate.fillAfter = true
    views!!.layoutMapInfo.startAnimation(animate)
}

Top to Bottom or Slide to Down

private fun slideDown() {
    if (isMapInfoShown) {
        isMapInfoShown = false
        val animate = TranslateAnimation(

Kotlin Extensions for Visible and Gone

fun View.visible() {
    this.visibility = View.VISIBLE
}


fun View.gone() {
    this.visibility = View.GONE
}

In this case, to validate Date (DD-MM-YYYY) or (DD/MM/YYYY), with a year between 1900 and 2099,like this with month and Days validation

if (!Regex.Match(txtDob.Text, @"^(0[1-9]|1[0-9]|2[0-9]|3[0,1])([/+-])(0[1-9]|1[0-2])([/+-])(19|20)[0-9]{2}$").Success)                  
{
   MessageBox.Show("InValid Date of Birth");
   txtDob.Focus();
}

You're already doing it!

save() will check if something in the model has changed. If it hasn't it won't run a db query.

Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate:

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}

The getDirty() method simply compares the current attributes with a copy saved in original when the model is created. This is done in the syncOriginal() method:

public function __construct(array $attributes = array())
{
    $this->bootIfNotBooted();

    $this->syncOriginal();

    $this->fill($attributes);
}

public function syncOriginal()
{
    $this->original = $this->attributes;

    return $this;
}

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}

Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

As highlighted in other answer(s) we can simply use command git status and then look for files listed under Unmerged paths:

The shells above will do the trick, and you could even convert them to an alias (you may need to wrap in a function to handle parameters):

alias myWatch='_() { while :; do clear; $2; sleep $1; done }; _'

Examples:

myWatch 1 ls ## Self-explanatory
myWatch 5 "ls -lF $HOME" ## Every 5 seconds, list out home directory; double-quotes around command to keep its arguments together

Alternately, Homebrew can install the watch from http://procps.sourceforge.net/:

brew install watch

If you install a JDK and choose to install sources too, the src.zip contains the source of ALL the public Java classes. Most of these have pretty good javadoc.

After further investigating on PSExec tool, I think I got the answer. I need to add -i option to tell PSExec to launch process on remote in interactive mode:

PSExec \\RPC001 -i -u myID -p myPWD PowerShell C:\script\StartPS.ps1 par1 par2

Without -i, powershell.exe is running on the remote in waiting mode. Interesting point is that if I run a simple bat (without PS in bat), it works fine. Maybe this is something special for PS case? Welcome comments and explanations.

You can handle the fds yourself. The exec in java returns a Process object. Intermittently check if the process is still running. Once it has completed close the processes STDERR, STDIN, and STDOUT streams (e.g. proc.getErrorStream.close()). That will mitigate the leaks.

To define a 3 column grid you could use the customizer or download the source set your less variables and recompile.

To learn more about the grid and the columns / gutter widths, please also read:

• Bootstrap 3 - Set Container Width to 940px Maximum for Desktops?
• Why does Bootstrap 3 force the container width to certain sizes?
• Bootstrap 3 Gutter Size
• Reduce the gutter (default 30px) on smaller devices in Bootstrap3?

In you case with a container of 960px consider the medium grid (see also: http://getbootstrap.com/css/#grid). This grid will have a max container width of 970px. When setting @grid-columns:3; and setting @grid-gutter-width:15px; in variables.less you will get:

15px | 1st column (298.33) | 15px | 2nd column (298.33) |15px | 3th column (298.33) | 15px

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

If you would like to handle multiple inputs with one handler take a look at my approach where I'm using computed property to get value of the input based on it's name.

import React, { useState } from "react";
import "./style.css";

export default function App() {
  const [state, setState] = useState({
    name: "John Doe",
    email: "[email protected]"
  });

  const handleChange = e => {
    setState({
      [e.target.name]: e.target.value
    });
  };

  return (
    <div>
      <input
        type="text"
        className="name"
        name="name"
        value={state.name}
        onChange={handleChange}
      />

      <input
        type="text"
        className="email"
        name="email"
        value={state.email}
        onChange={handleChange}
      />
    </div>
  );
}

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

you have to rename each column

SELECT col1 as MyCol1,
       col2 as MyCol2,
 .......
 FROM `foobar`

Solved using a solution i found googling by Yogi Anand: https://productforums.google.com/d/msg/docs/3qsR2m-1Xx8/sSU6Z6NYLOcJ

The example below counts the number of non-empty rows in the range A3:C, remember to update both ranges in the formula with your range of interest.

=ArrayFormula(SUM(SIGN(MMULT(LEN(A3:C), TRANSPOSE(SIGN(COLUMN(A3:C)))))))

Also make sure to avoid circular dependencies, it will happen if you for example count the number of non-empty rows in A:C and place this formula in the A or C column.

Try like this: server.bind(("0.0.0.0", 6677))

I think introduction to Algorithms is the reference books, and a must have for any serious programmer.

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

Other fun book is The algorithm design manual http://www.algorist.com/. It covers more sophisticated algorithms.

I can't not mention The art of computer programming of Knuth http://www-cs-faculty.stanford.edu/~knuth/taocp.html

As Victor pointed out, the problem is with the alias. This can be avoided though, by putting the expression directly into the WHERE x IN y clause:

SELECT `users`.`first_name`,`users`.`last_name`,`users`.`email`,SUBSTRING(`locations`.`raw`,-6,4) AS `guaranteed_postcode`
FROM `users` LEFT OUTER JOIN `locations`
ON `users`.`id` = `locations`.`user_id`
WHERE SUBSTRING(`locations`.`raw`,-6,4) NOT IN #this is where the fake col is being used
(
 SELECT `postcode` FROM `postcodes` WHERE `region` IN
 (
  'australia'
 )
)

However, I guess this is very inefficient, since the subquery has to be executed for every row of the outer query.

num < 0 // number is negative

function run() {
    window.setTimeout(
         "run()",
         1000
    );
}

You've mentioned that they each have their own machines, but if they need to log onto a co-workers machine, and then use the file, saving it through "C:\Users\Public\Desktop\" will make it available to different usernames.

Public Sub SaveToDesktop()
    ThisWorkbook.SaveAs Filename:="C:\Users\Public\Desktop\" & ThisWorkbook.Name & "_copy", _ 
    FileFormat:=xlOpenXMLWorkbookMacroEnabled
End Sub

I'm not sure whether this would be a requirement, but may help!

Linkage determines whether identifiers that have identical names refer to the same object, function, or other entity, even if those identifiers appear in different translation units. The linkage of an identifier depends on how it was declared. There are three types of linkages:

1. Internal linkage : identifiers can only be seen within a translation unit.
2. External linkage : identifiers can be seen (and referred to) in other translation units.
3. No linkage : identifiers can only be seen in the scope in which they are defined. Linkage does not affect scoping

C++ only : You can also have linkage between C++ and non-C++ code fragments, which is called language linkage.

$('#checkbox').prop('checked', true);

When you want it unchecked:

$('#checkbox').prop('checked', false);

Selected date at the example is interesting. Example code block is:

Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30);  //January 30th 2000
Date sDate = c1.getTime();

System.out.println(sDate);

and output Wed Mar 01 19:32:21 JST 2000.

When I first read the example i think that output is wrong but it is true:)

• Calendar.Month is starting from 0 so 1 means February.
• February last day is 28 so output should be 2 March.
• But selected year is important, it is 2000 which means February 29 so result should be 1 March.

If you're able to run PHP scripts you can give PHP MongoDB Admin a try. It's a single PHP script that gives you basic management and searching functionality.

Basically Multi-programming is a concept where you run more than one program simultaneously, suppose you run two programs like chrome(browser) and calculator(system application).

Multi processing is where a user uses more than one processor to accomplish a task.

To know Multi threading we need to know what is a thread. A thread is basically a part of a program running within the program. Best example of thread is the tabs of a browser. If you have 5 tabs which are being opened and used then the program actually creates 5 threads of the program, this concept is called multi-threading.

Use ON DUPLICATE KEY UPDATE ...,
Negative : because the UPDATE uses resources for the second action.

Use INSERT IGNORE ...,
Negative : MySQL will not show any errors if something goes wrong, so you cannot handle the errors. Use it only if you don’t care about the query.

To convert a Decimal to scientific notation without needing to specify the precision in the format string, and without including trailing zeros, I'm currently using

def sci_str(dec):
    return ('{:.' + str(len(dec.normalize().as_tuple().digits) - 1) + 'E}').format(dec)

print( sci_str( Decimal('123.456000') ) )    # 1.23456E+2

To keep any trailing zeros, just remove the normalize().

After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.

You can simply add this to your config.xml, which can be found in your application's root directory:

Recommended in the documentation:

<allow-navigation href="http://example.com/*" />

or:

<allow-navigation href="http://*/*" />

From the plugin's documentation:

Navigation Whitelist

Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.

Quirks: on Android it also applies to iframes for non-http(s) schemes.

By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:

<!-- Allow links to example.com -->
<allow-navigation href="http://example.com/*" />

<!-- Wildcards are allowed for the protocol, as a prefix
     to the host, or as a suffix to the path -->
<allow-navigation href="*://*.example.com/*" />

<!-- A wildcard can be used to whitelist the entire network,
     over HTTP and HTTPS.
     *NOT RECOMMENDED* -->
<allow-navigation href="*" />

<!-- The above is equivalent to these three declarations -->
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />

Prerequisite:

Your APK needs to be signed by system as correctly pointed out earlier. One way to achieve that is building the AOSP image yourself and adding the source code into the build.

Code:

Once installed as a system app, you can use the package manager methods to install and uninstall an APK as following:

Install:

public boolean install(final String apkPath, final Context context) {
    Log.d(TAG, "Installing apk at " + apkPath);
    try {
        final Uri apkUri = Uri.fromFile(new File(apkPath));
        final String installerPackageName = "MyInstaller";
        context.getPackageManager().installPackage(apkUri, installObserver, PackageManager.INSTALL_REPLACE_EXISTING, installerPackageName);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

Uninstall:

public boolean uninstall(final String packageName, final Context context) {
    Log.d(TAG, "Uninstalling package " + packageName);
    try {
        context.getPackageManager().deletePackage(packageName, deleteObserver, PackageManager.DELETE_ALL_USERS);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

To have a callback once your APK is installed/uninstalled you can use this:

/**
 * Callback after a package was installed be it success or failure.
 */
private class InstallObserver implements IPackageInstallObserver {

    @Override
    public void packageInstalled(String packageName, int returnCode) throws RemoteException {

        if (packageName != null) {
            Log.d(TAG, "Successfully installed package " + packageName);
            callback.onAppInstalled(true, packageName);
        } else {
            Log.e(TAG, "Failed to install package.");
            callback.onAppInstalled(false, null);
        }
    }

    @Override
    public IBinder asBinder() {
        return null;
    }
}

/**
 * Callback after a package was deleted be it success or failure.
 */
private class DeleteObserver implements IPackageDeleteObserver {

    @Override
    public void packageDeleted(String packageName, int returnCode) throws RemoteException {
        if (packageName != null) {
            Log.d(TAG, "Successfully uninstalled package " + packageName);
            callback.onAppUninstalled(true, packageName);
        } else {
            Log.e(TAG, "Failed to uninstall package.");
            callback.onAppUninstalled(false, null);
        }
    }

    @Override
    public IBinder asBinder() {
        return null;
    }
}

/**
 * Callback to give the flow back to the calling class.
 */
public interface InstallerCallback {
    void onAppInstalled(final boolean success, final String packageName);
    void onAppUninstalled(final boolean success, final String packageName);
}

If you are using an ActionBarActivity then you can tell Android to use the Toolbar as the ActionBar like so:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);

And then calls to

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);

will work. You can also use that in Fragments that are attached to ActionBarActivities you can use it like this:

((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);

If you are not using ActionBarActivities or if you want to get the back arrow on a Toolbar that's not set as your SupportActionBar then you can use the following:

mActionBar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
mActionBar.setNavigationOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
       //What to do on back clicked
   }
});

If you are using android.support.v7.widget.Toolbar, then you should add the following code to your AppCompatActivity:

@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}

SOLUTION

The following code worked for me with jQuery. It works in every browser and allows to preserve events and custom properties.

var $el = $('#your-input-id');
$el.wrap('<form>').closest('form').get(0).reset();
$el.unwrap();

DEMO

See this jsFiddle for code and demonstration.

To compare, there are more options:

import (
    "fmt"
    "regexp"
    "strings"
)

const (
    str    = "something"
    substr = "some"
)

// 1. Contains
res := strings.Contains(str, substr)
fmt.Println(res) // true

// 2. Index: check the index of the first instance of substr in str, or -1 if substr is not present
i := strings.Index(str, substr)
fmt.Println(i) // 0

// 3. Split by substr and check len of the slice, or length is 1 if substr is not present
ss := strings.Split(str, substr)
fmt.Println(len(ss)) // 2

// 4. Check number of non-overlapping instances of substr in str
c := strings.Count(str, substr)
fmt.Println(c) // 1

// 5. RegExp
matched, _ := regexp.MatchString(substr, str)
fmt.Println(matched) // true

// 6. Compiled RegExp
re = regexp.MustCompile(substr)
res = re.MatchString(str)
fmt.Println(res) // true

Benchmarks: Contains internally calls Index, so the speed is almost the same (btw Go 1.11.5 showed a bit bigger difference than on Go 1.14.3).

Related to @[Igor Nikolaev]'s answer from 8 years ago, using an Answer can be simplified somewhat using a lambda expression available in Java 8.

when(someMock.someMethod()).thenAnswer(invocation -> {
    doStuff();
    return;
});

or more simply:

when(someMock.someMethod()).thenAnswer(invocation -> doStuff());

I came up with this importable module function. It uses the gmail email server in this example. Its split into header and message so you can clearly see whats going on:

import smtplib

def send_alert(subject=""):

    to = ['[email protected]', 'email2@another_email.com', '[email protected]']
    gmail_user = '[email protected]'
    gmail_pwd = 'my_pass'
    smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
    smtpserver.ehlo()
    smtpserver.starttls()
    smtpserver.ehlo
    smtpserver.login(gmail_user, gmail_pwd)
    header = 'To:' + ", ".join(to) + '\n' + 'From: ' + gmail_user + '\n' + 'Subject: ' + subject + '\n'
    msg = header + '\n' + subject + '\n\n'
    smtpserver.sendmail(gmail_user, to, msg)
    smtpserver.close()

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

This is one approach:

from xlrd import open_workbook

class Arm(object):
    def __init__(self, id, dsp_name, dsp_code, hub_code, pin_code, pptl):
        self.id = id
        self.dsp_name = dsp_name
        self.dsp_code = dsp_code
        self.hub_code = hub_code
        self.pin_code = pin_code
        self.pptl = pptl

    def __str__(self):
        return("Arm object:\n"
               "  Arm_id = {0}\n"
               "  DSPName = {1}\n"
               "  DSPCode = {2}\n"
               "  HubCode = {3}\n"
               "  PinCode = {4} \n"
               "  PPTL = {5}"
               .format(self.id, self.dsp_name, self.dsp_code,
                       self.hub_code, self.pin_code, self.pptl))

wb = open_workbook('sample.xls')
for sheet in wb.sheets():
    number_of_rows = sheet.nrows
    number_of_columns = sheet.ncols

    items = []

    rows = []
    for row in range(1, number_of_rows):
        values = []
        for col in range(number_of_columns):
            value  = (sheet.cell(row,col).value)
            try:
                value = str(int(value))
            except ValueError:
                pass
            finally:
                values.append(value)
        item = Arm(*values)
        items.append(item)

for item in items:
    print item
    print("Accessing one single value (eg. DSPName): {0}".format(item.dsp_name))
    print

You don't have to use a custom class, you can simply take a dict(). If you use a class however, you can access all values via dot-notation, as you see above.

Here is the output of the script above:

Arm object:
  Arm_id = 1
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282001 
  PPTL = 1
Accessing one single value (eg. DSPName): JaVAS

Arm object:
  Arm_id = 2
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282002 
  PPTL = 3
Accessing one single value (eg. DSPName): JaVAS

Arm object:
  Arm_id = 3
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282003 
  PPTL = 5
Accessing one single value (eg. DSPName): JaVAS

Another solution that does not involve converting to/from strings:

from math import log10

def decompose(n):
    if n == 0:
        return [0]
    b = int(log10(n)) + 1
    return [(n // (10 ** i)) % 10 for i in reversed(range(b))]

This is one of the few cases where I find the test:

if(! argument2) {  

}

works quite nicely and carries the correct implication syntactically.

(With the simultaneous restriction that I wouldn't allow a legitimate null value for argument2 which has some other meaning; but that would be really confusing.)

EDIT:

This is a really good example of a stylistic difference between loosely-typed and strongly-typed languages; and a stylistic option that javascript affords in spades.

My personal preference (with no criticism meant for other preferences) is minimalism. The less the code has to say, as long as I'm consistent and concise, the less someone else has to comprehend to correctly infer my meaning.

One implication of that preference is that I don't want to - don't find it useful to - pile up a bunch of type-dependency tests. Instead, I try to make the code mean what it looks like it means; and test only for what I really will need to test for.

One of the aggravations I find in some other peoples' code is needing to figure out whether or not they expect, in the larger context, to actually run into the cases they are testing for. Or if they are trying to test for everything possible, on the chance that they don't anticipate the context completely enough. Which means I end up needing to track them down exhaustively in both directions before I can confidently refactor or modify anything. I figure that there's a good chance they might have put those various tests in place because they foresaw circumstances where they would be needed (and which usually aren't apparent to me).

(I consider that a serious downside in the way these folks use dynamic languages. Too often people don't want to give up all the static tests, and end up faking it.)

I've seen this most glaringly in comparing comprehensive ActionScript 3 code with elegant javascript code. The AS3 can be 3 or 4 times the bulk of the js, and the reliability I suspect is at least no better, just because of the number (3-4X) of coding decisions that were made.

As you say, Shog9, YMMV. :D

When getting the substring of a CLOB column and using a query tool that has size/buffer restrictions sometimes you would need to set the BUFFER to a larger size. For example while using SQL Plus use the SET BUFFER 10000 to set it to 10000 as the default is 4000.

Running the DBMS_LOB.substr command you can also specify the amount of characters you want to return and the offset from which. So using DBMS_LOB.substr(column, 3000) might restrict it to a small enough amount for the buffer.

See oracle documentation for more info on the substr command

    DBMS_LOB.SUBSTR (
       lob_loc     IN    CLOB   CHARACTER SET ANY_CS,
       amount      IN    INTEGER := 32767,
       offset      IN    INTEGER := 1)
      RETURN VARCHAR2 CHARACTER SET lob_loc%CHARSET;

.Click() - Perform only click operation as like mouse click.

.Submit() - Perform Enter operation as like keyboard Enter event.

For Example. Consider a login page where it contains username and password and submit button.

On filling password if we want to login without clicking login button. we need to user .submit button on password where .click() operation does not work.[to login into application]

Brif.

driver.get("https:// anyURL"); 
driver.manage().window().maximize(); 
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
driver.findElement(By.id("txtUserId")).sendKeys("[email protected]"); 
WebElement text = driver.findElement(By.id("txtPassword")); text.sendKeys("password"); 
Thread.sleep(1000); 
text.click();   //This will not work - it will on perform click operation not submit operation
text.submit(); //This will perform submit operation has enter key 

When I did just a remove the option remained in the ddl on the view, but was gone in the html (if u inspect the page)

$("#ddlSelectList option[value='2']").remove(); //removes the option with value = 2
$('#ddlSelectList').val('').trigger('chosen:updated'); //refreshes the drop down list

That can be done using the limit function, this might not seem new but i have added something.The code should go:

SELECT * FROM table_name LIMIT 100,10;

for the above case assume that you have 110 rows from the table and you want to select the last ten, 100 is the row you want to start to print(if you are to print), and ten shows how many rows you want to pick from the table. For a more precised way you can start by selecting all the rows you want to print out and then you grab the last row id if you have an id column(i recommend you put one) then subtract ten from the last id number and that will be where you want to start, this will make your program to function autonomously and for any number of rows, but if you write the value directly i think you will have to change the code every time data is inserted into your table.I think this helps.Pax et Bonum.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

Since there are a ton of ways to accomplish the desired results and so many people provided !in_array() as an answer, and the OP already mentions the use of array_unique, I would like to provide a couple alternatives.

Using array_diff (php >= 4.0.1 || 5) you can filter out only the new array values that don't exist. Alternatively you can also compare the keys and values with array_diff_assoc. http://php.net/manual/en/function.array-diff.php

$currentValues = array(1, 2);
$newValues = array(1, 3, 1, 4, 2);
var_dump(array_diff($newValues, $currentValues));

Result:

Array
(
    [1] => 3
    [3] => 4
)

http://ideone.com/SWO3D1

Another method is using array_flip to assign the values as keys and compare them using isset, which will perform much faster than in_array with large datasets. Again this filters out just the new values that do not already exist in the current values.

$currentValues = [1, 2];
$newValues = [1, 3, 1, 4, 2];
$a = array();
$checkValues = array_flip($currentValues);
foreach ($newValues as $v) {
    if (!isset($checkValues[$v])) {
        $a[] = $v;
    }
}

Result:

Array
(
    [0] => 3
    [1] => 4
)

http://ideone.com/cyRyzN

With either method you can then use array_merge to append the unique new values to your current values.

1. http://ideone.com/JCakmR
2. http://ideone.com/bwTz2u

Result:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
)

Absolutely position divs over the text area with a z-index higher and give these divs a transparent GIF background graphic.

Note after a bit more thought - You'd need to have these 'covers' be linked so clicking on them would take you to where the tab was supposed to, which means you could/should do this with the anchor element set to display:box, width and height set as well as the transparent background image.

Recent updates enabled computers with AMD processors to run Android Emulator and you don't need to install ARM images anymore. Taken from the Android Developers blog:

If you have an AMD processor in your computer you need the following setup requirements to be in place:

• AMD Processor - Recommended: AMD® Ryzen™ processors
  
• Android Studio 3.2 Beta or higher
  
• Android Emulator v27.3.8+
  
• x86 Android Virtual Device (AVD)
  
• Windows 10 with April 2018 Update
  
• Enable via Windows Features: "Windows Hypervisor Platform"
  

The important point is enabling Windows Hypervisor Platform and that's it! I strongly recommend reading the whole blog post:
https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html

It is not a compilation error at all! You can import a default package to a default package class only.

If you do so for another package, then it shall be a compilation error.

As already stated both System.Threading.Timer and System.Timers.Timer will work. The big difference between the two is that System.Threading.Timer is a wrapper arround the other one.

System.Threading.Timer will have more exception handling while System.Timers.Timer will swallow all the exceptions.

This gave me big problems in the past so I would always use 'System.Threading.Timer' and still handle your exceptions very well.

To get a count of the number of unique combinations of id, name and address:

SELECT Count(*)
FROM   (
        SELECT DISTINCT
               id
             , name
             , address
        FROM   your_table
       ) As distinctified

To avoid regex hell you could find your first match, chop off a chunk then attempt to find the next one on the substring. In C# this looks something like this, sorry I've not ported it over to JavaScript for you.

        long count = 0;
        var remainder = data;
        Match match = null;
        do
        {
            match = _rgx.Match(remainder);
            if (match.Success)
            {
                count++;
                remainder = remainder.Substring(match.Index + 1, remainder.Length - (match.Index+1));
            }
        } while (match.Success);
        return count;

For anyone looks for a shorthand way, to add transition for all properties except for one specific property with delay, be aware of there're differences among even modern browsers.

A simple demo below shows the difference. Check out full code

div:hover {
  width: 500px;
  height: 500px;
  border-radius: 0;
  transition: all 2s, border-radius 2s 4s;
}

Chrome will "combine" the two animation (which is like I expect), like below:

While Safari "separates" it (which may not be expected):

A more compatible way is that you assign the specific transition for specific property, if you have a delay for one of them.

If you want to mirror same content from source to destination, try following one.

function CopyFilesToFolder ($fromFolder, $toFolder) {
    $childItems = Get-ChildItem $fromFolder
    $childItems | ForEach-Object {
         Copy-Item -Path $_.FullName -Destination $toFolder -Recurse -Force
    }
}

Test:

CopyFilesToFolder "C:\temp\q" "c:\temp\w"

To access the mysql command in Windows without manually changing directories, do this:

• Go to Control Panel > System > Advanced system settings.
• System Properties will appear.
• Click on the 'Advanced' tab.
• Click 'Environment Variables'.
• Under System Variables, locate 'Path' and click Edit.

• Append the path to your MySQL installation to the end of the exisiting 'Variable value'. Example:

  %systemDrive%\xampp\mysql\bin\ 

  or, if you prefer

  c:\xampp\mysql\bin\ 

• Finally, open a new command prompt to make this change take effect.

Note that MySQL's documentation on Setting Environment Variables has little to say about handling this in Windows.

I have a gradle project and when my build.gradle dependencies section looks like this:

    compileOnly 'org.projectlombok:lombok:1.18.4'
    apt 'org.projectlombok:lombok:1.18.4'
}

it leads to this exception:

java.lang.NoSuchMethodError: org.hamcrest.Matcher.describeMismatch(Ljava/lang/Object;Lorg/hamcrest/Description;)V

    at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:18)

to fix this issue, I've substituted "mockito-all" with "mockito-core".

mockito-all.jar besides Mockito itself contains also (as of 1.9.5) two dependencies: Hamcrest and Objenesis (let’s omit repackaged ASM and CGLIB for a moment). The reason was to have everything what is needed inside an one JAR to just put it on a classpath. It can look strange, but please remember than Mockito development started in times when pure Ant (without dependency management) was the most popular build system for Java projects and the all external JARs required by a project (i.e. our project’s dependencies and their dependencies) had to be downloaded manually and specified in a build script.

On the other hand mockito-core.jar is just Mockito classes (also with repackaged ASM and CGLIB). When using it with Maven or Gradle required dependencies (Hamcrest and Objenesis) are managed by those tools (downloaded automatically and put on a test classpath). It allows to override used versions (for example if our projects uses never, but backward compatible version), but what is more important those dependencies are not hidden inside mockito-all.jar what allows to detected possible version incompatibility with dependency analyze tools. This is much better solution when dependency managed tool is used in a project.

System.out.print("Enter a Value: ");
val = s.nextInt();

This line is placed in last.The whole code is as follows:-

public static void main(String[] args){
    int min, max;

    Scanner s = new Scanner(System.in);
    System.out.print("Enter a Value: ");
    int val = s.nextInt();
    min = max = val;

    while (val != 0) {
        if (val < min) {
            min = val;
        }
        if (val > max) {
            max = val;
        }
        System.out.print("Enter a Value: ");
        val = s.nextInt();

    }
    System.out.println("Min: " + min);
    System.out.println("Max: " + max);
}

It's a hexadecimal number.

0x6400 translates to 4*16^2 + 6*16^3 = 25600

Technically this will work...

String name = new Object(){}.getClass().getEnclosingMethod().getName();

However, a new anonymous inner class will be created during compile time (e.g. YourClass$1.class). So this will create a .class file for each method that deploys this trick. Additionally, an otherwise unused object instance is created on each invocation during runtime. So this may be an acceptable debug trick, but it does come with significant overhead.

An advantage of this trick is that getEnclosingMethod() returns java.lang.reflect.Method which can be used to retrieve all other information of the method including annotations and parameter names. This makes it possible to distinguish between specific methods with the same name (method overload).

Note that according to the JavaDoc of getEnclosingMethod() this trick should not throw a SecurityException as inner classes should be loaded using the same class loader. So there is no need to check the access conditions even if a security manager is present.

Please be aware: It is required to use getEnclosingConstructor() for constructors. During blocks outside of (named) methods, getEnclosingMethod() returns null.

Creating Custom ProgressBar like hotstar.

1. Add Progress bar on layout file and set the indeterminateDrawable with drawable file.

activity_main.xml

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:id="@+id/player_progressbar"
    android:indeterminateDrawable="@drawable/custom_progress_bar"
    />

2. Create new xml file in res\drawable

custom_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
    <rotate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="2000"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="1080" >

    <shape
        android:innerRadius="35dp"
        android:shape="ring"
        android:thickness="3dp"
        android:useLevel="false" >
       <size
           android:height="80dp"
           android:width="80dp" />

       <gradient
            android:centerColor="#80b7b4b2"
            android:centerY="0.5"
            android:endColor="#f4eef0"
            android:startColor="#00938c87"
            android:type="sweep"
            android:useLevel="false" />
    </shape>

</rotate>

Try using this this.getClass().getCanonicalName() or this.getClass().getSimpleName(). If it's an anonymous class, use this.getClass().getSuperclass().getName()

Another way of configuring backup options is via the Customize interface. Enter:

M-x customize-group

And then at the Customize group: prompt enter backup.

If you scroll to the bottom of the buffer you'll see Backup Directory Alist. Click Show Value and set the first entry of the list as follows:

Regexp matching filename: .*
Backup directory name: /path/to/your/backup/dir

Alternatively, you can turn backups off my setting Make Backup Files to off.

If you don't want Emacs to automatically edit your .emacs file you'll want to set up a customisations file.

In order to eliminate this error, you have to fo to the wp-config file and add these lines of code

define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors',0);

Others have answered the question, but just for the fun of it, here is a visual dice throwing example, using the Math.random javascript method, a background image and some recursive timeouts.

It is not quite as baked-in in Java, so you don't get this for free. It is done with convention rather than language constructs. In all data transfer classes (and maybe even in all classes you write...), you should implement a sensible toString method. So here you need to override toString() in your Person class and return the desired state.

There are utilities available that help with writing a good toString method, or most IDEs have an automatic toString() writing shortcut.

A good way to findout what header file you are missing:

 man <section> <function call>

To find out the section use:

apropos <function call>

Example:

 man 3 memset
 man 2 send

Edit in response to James Morris:

• Section | Description
• 1 General commands
• 2 System calls
• 3 C library functions
• 4 Special files (usually devices, those found in /dev) and drivers
• 5 File formats and conventions
• 6 Games and screensavers
• 7 Miscellanea
• 8 System administration commands and daemons

Not mentioned but can help in some instances:

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState !== 4) return;
    if (xhr.status === 200) {
        var doc = iframe.contentWindow.document;
        doc.open();
        doc.write(xhr.responseText);
        doc.close();
    }
}
xhr.open('GET', url, true);
xhr.send(null);

Actually, to query the team_name, just add it in brackets to the last line. Apart from that, it seems to work on Python 2.7.3 on command line.

from urllib2 import urlopen
import json

url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
response = urlopen(url)
json_obj = json.load(response)

for i in json_obj['team']:
    print i['team_name']

for horizontal lines you can use hr tag:

hr { width: 90%; }

but its not possible to limit border height. only element height.

I excluded the root ("/") mount point by using grep -vw "^/".

# cat /tmp/topfsfind.txt| head -4 |awk '{print $NF}'
/
/root/.m2
/root
/var

# cat /tmp/topfsfind.txt| head -4 |awk '{print $NF}' | grep -vw "^/"
/root/.m2
/root
/var

<input type="text" autocomplete="off" />

Use return statement anywhere you want to exit from function.

if(somecondtion)
   return;

if(somecondtion)
   return false;

You can include a .js file which has the script to set the

window.location.href = url;

Where url would be the url you wish to load.

I'm not sure if this answers your question, but for example:

if (A || B)
{
    Console.WriteLine("Or");
}

if (A && B)
{
    Console.WriteLine("And");
}

If you change your property to use a backing field (instead of an automatic property), you can do the following:

public event EventHandler ImageFullPath1Changed;
private string _imageFullPath1 = string.Empty;

public string ImageFullPath1 
{
  get
  {
    return imageFullPath1 ;
  }
  set
  {
    if (_imageFullPath1 != value)
    { 
      _imageFullPath1 = value;

      EventHandler handler = ImageFullPathChanged;
      if (handler != null)
        handler(this, e);
    }
  }
}

Changing the address's port number (localhost:) worked for me :)

You may well want to use JSON-P instead (see below). First a quick explanation.

The header you've mentioned is from the Cross Origin Resource Sharing standard. Beware that it is not supported by some browsers people actually use, and on other browsers (Microsoft's, sigh) it requires using a special object (XDomainRequest) rather than the standard XMLHttpRequest that jQuery uses. It also requires that you change server-side resources to explicitly allow the other origin (www.xxxx.com).

To get the JSON data you're requesting, you basically have three options:

1. If possible, you can be maximally-compatible by correcting the location of the files you're loading so they have the same origin as the document you're loading them into. (I assume you must be loading them via Ajax, hence the Same Origin Policy issue showing up.)

2. Use JSON-P, which isn't subject to the SOP. jQuery has built-in support for it in its ajax call (just set dataType to "jsonp" and jQuery will do all the client-side work). This requires server side changes, but not very big ones; basically whatever you have that's generating the JSON response just looks for a query string parameter called "callback" and wraps the JSON in JavaScript code that would call that function. E.g., if your current JSON response is:

   {"weather": "Dreary start but soon brightening into a fine summer day."}
   

   Your script would look for the "callback" query string parameter (let's say that the parameter's value is "jsop123") and wraps that JSON in the syntax for a JavaScript function call:

   jsonp123({"weather": "Dreary start but soon brightening into a fine summer day."});
   

   That's it. JSON-P is very broadly compatible (because it works via JavaScript script tags). JSON-P is only for GET, though, not POST (again because it works via script tags).

3. Use CORS (the mechanism related to the header you quoted). Details in the specification linked above, but basically:

   A. The browser will send your server a "preflight" message using the OPTIONS HTTP verb (method). It will contain the various headers it would send with the GET or POST as well as the headers "Origin", "Access-Control-Request-Method" (e.g., GET or POST), and "Access-Control-Request-Headers" (the headers it wants to send).

   B. Your PHP decides, based on that information, whether the request is okay and if so responds with the "Access-Control-Allow-Origin", "Access-Control-Allow-Methods", and "Access-Control-Allow-Headers" headers with the values it will allow. You don't send any body (page) with that response.

   C. The browser will look at your response and see whether it's allowed to send you the actual GET or POST. If so, it will send that request, again with the "Origin" and various "Access-Control-Request-xyz" headers.

   D. Your PHP examines those headers again to make sure they're still okay, and if so responds to the request.

   In pseudo-code (I haven't done much PHP, so I'm not trying to do PHP syntax here):

   // Find out what the request is asking for
   corsOrigin = get_request_header("Origin")
   corsMethod = get_request_header("Access-Control-Request-Method")
   corsHeaders = get_request_header("Access-Control-Request-Headers")
   if corsOrigin is null or "null" {
       // Requests from a `file://` path seem to come through without an
       // origin or with "null" (literally) as the origin.
       // In my case, for testing, I wanted to allow those and so I output
       // "*", but you may want to go another way.
       corsOrigin = "*"
   }
   
   // Decide whether to accept that request with those headers
   // If so:
   
   // Respond with headers saying what's allowed (here we're just echoing what they
   // asked for, except we may be using "*" [all] instead of the actual origin for
   // the "Access-Control-Allow-Origin" one)
   set_response_header("Access-Control-Allow-Origin", corsOrigin)
   set_response_header("Access-Control-Allow-Methods", corsMethod)
   set_response_header("Access-Control-Allow-Headers", corsHeaders)
   if the HTTP request method is "OPTIONS" {
       // Done, no body in response to OPTIONS
       stop
   }
   // Process the GET or POST here; output the body of the response
   

   Again stressing that this is pseudo-code.

Use this:

myFunction.bookName = 'mybook';
myFunction.bookdesc = 'new';

Or, if you are using jQuery:

$(myFunction).extend({
    bookName:'mybook',
    bookdesc: 'new'
});

The push method is wrong because it belongs to the Array.prototype object.

To create a named object, try this:

var myObj = function(){
    this.property = 'foo';
    this.bar = function(){
    }
}
myObj.prototype.objProp = true;
var newObj = new myObj();

Another approach can be manually using batch rename option

Right click on the file -> File Custom Commands -> Batch Rename and you can replace h. with half.

This will work for linux based gui using WinSCP etc

Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct(). Otherwise you get one user multiple times:

users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

For newer version of Git.

I tried git add -A and this prompted,

warning: The behavior of 'git add --all (or -A)' with no path argument from a subdirectory of the tree will change in Git 2.0 and should not be used anymore. To add content for the whole tree, run:

git add --all :/ (or git add -A :/)

To restrict the command to the current directory, run:

git add --all . (or git add -A .)

With the current Git version, the command is restricted to the current directory.

Then I tried below which worked.

git add --all :/

Carbon Extension

Here is the one of the better solutions.

DECLARE @i int
            DECLARE @curren_val int
            DECLARE @numrows int
            create table #Practitioner (idx int IDENTITY(1,1), PractitionerId int)
            INSERT INTO #Practitioner (PractitionerId) values (10),(20),(30)
            SET @i = 1
            SET @numrows = (SELECT COUNT(*) FROM #Practitioner)
            IF @numrows > 0
            WHILE (@i <= (SELECT MAX(idx) FROM #Practitioner))
            BEGIN

                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here
                PRINT @curren_val
                SET @i = @i + 1
            END

Here i've add some values in the table beacuse, initially it is empty.

We can access or we can do anything in the body of the loop and we can access the idx by defining it inside the table definition.

              BEGIN
                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here

                PRINT @curren_val
                SET @i = @i + 1
            END

Adding a quick snippet to have it ready to execute:

Source: myparser.py

import argparse
parser = argparse.ArgumentParser(description="Flip a switch by setting a flag")
parser.add_argument('-w', action='store_true')

args = parser.parse_args()
print args.w

Usage:

python myparser.py -w
>> True

You can use checkout or co

$ svn co http://example.com/svn/app-name directory-name

Some short codes:-

1. checkout (co)
2. commit (ci)
3. copy (cp)
4. delete (del, remove,rm)
5. diff (di)

You can change the global tint color in your storyboard by clicking on an empty space on the board and select in the right toolbar "Show the file inspector", and you will see in the bottom of the toolbar the "Global Tint" option.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path class that allows to do this straight away:

With all the path in one String:

Path.of("/tmp/foo");

With the path broken down in several Strings:

Path.of("/tmp","foo");

[Update Sep 2016]: This answer was intended for docker compose file v1 (as shown by the sample compose file below). For v2, see the other answer by @Windsooon.

[Original answer]:

It is pretty clear in the documentation. depends_on decides the dependency and the order of container creation and links not only does these, but also

Containers for the linked service will be reachable at a hostname identical to the alias, or the service name if no alias was specified.

For example, assuming the following docker-compose.yml file:

web:
  image: example/my_web_app:latest
  links:
    - db
    - cache

db:
  image: postgres:latest

cache:
  image: redis:latest

With links, code inside web will be able to access the database using db:5432, assuming port 5432 is exposed in the db image. If depends_on were used, this wouldn't be possible, but the startup order of the containers would be correct.

Idea 8.1.3

Jar is ok, since there is compiled output in 'output' directory (project/out/production//)

I guess, you have to run 'make' before building jar

for dependencies just check "show library" and choose what you want.

A .java file is the code file. A .class file is the compiled file.

It's not exactly "conversion" - it's compilation. Suppose your file was called "herb.java", you would write (in the command prompt):

 javac herb.java

It will create a herb.class file in the current folder.

It is "executable" only if it contains a static void main(String[]) method inside it. If it does, you can execute it by running (again, command prompt:)

 java herb

You are using the JavaScript array.find() method. Note that this is standard JS, and has nothing to do with jQuery. In fact, your entire code in the question makes no use of jQuery at all.

You can find the documentation for array.find() here: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/find

If you scroll to the bottom of this page, you will note that it has browser support info, and you will see that it states that IE does not support this method.

Ironically, your best way around this would be to use jQuery, which does have similar functionality that is supported in all browsers.

i have been working on a dropdown replacement jquery plugin to combat this problem. As of this post, it is almost indistinguishable from a native dropdown in terms of look and functionality.

here is a demo (also a link to downloads): http://programmingdrunk.com/current-projects/dropdownReplacement/

here is the project page of the plugin:

http://plugins.jquery.com/project/dropdownreplacement

(update:) the jquery plugin page seems to no longer work. I will probably not put my plugin on their new site when they get it working, so feel free to use the programmingdrunk.com link for demo/download

I'll provide you with my vision of somebody who feels very uncomfortable in the Java world, which I assume is also your case.

What it is

A workspace is a concept of grouping together:

1. a set of (somehow) related projects
2. some configuration pertaining to all these projects
3. some settings for Eclipse itself

This happens by creating a directory and putting inside it (you don't have to do it, it's done for you) files that manage to tell Eclipse these information. All you have to do explicitly is to select the folder where these files will be placed. And this folder doesn't need to be the same where you put your source code - preferentially it won't be.

Exploring each item above:

1. a set of (somehow) related projects

Eclipse seems to always be opened in association with a particular workspace, i.e., if you are in a workspace A and decide to switch to workspace B (File > Switch Workspaces), Eclipse will close itself and reopen. All projects that were associated with workspace A (and were appearing in the Project Explorer) won't appear anymore and projects associated with workspace B will now appear. So it seems that a project, to be open in Eclipse, MUST be associated to a workspace.

Notice that this doesn't mean that the project source code must be inside the workspace. The workspace will, somehow, have a relation to the physical path of your projects in your disk (anybody knows how? I've looked inside the workspace searching for some file pointing to the projects paths, without success).

This way, a project can be inside more than 1 workspace at a time. So it seems good to keep your workspace and your source code separated.

2. some configuration pertaining to all these projects

I heard that something, like the Java compiler version (like 1.7, e.g - I don't know if 'version' is the word here), is a workspace-level configuration. If you have several projects inside your workspace, and compile them inside of Eclipse, all of them will be compiled with the same Java compiler.

3. some settings for Eclipse itself

Some things like your key bindings are stored at a workspace-level, also. So, if you define that ctrl+tab will switch tabs in a smart way (not stacking them), this will only be bound to your current workspace. If you want to use the same key binding in another workspace (and I think you want!), it seems that you have to export/import them between workspaces (if that's true, this IDE was built over some really strange premises). Here is a link on this.

It also seems that workspaces are not necessarily compatible between different Eclipse versions. This article suggests that you name your workspaces containing the name of the Eclipse version.

And, more important, once you pick a folder to be your workspace, don't touch any file inside there or you are in for some trouble.

How I think is a good way to use it

(actually, as I'm writing this, I don't know how to use this in a good way, that's why I was looking for an answer – that I'm trying to assemble here)

1. Create a folder for your projects:
   /projects

2. Create a folder for each project and group the projects' sub-projects inside of it:
   /projects/proj1/subproj1_1
/projects/proj1/subproj1_2
/projects/proj2/subproj2_1

3. Create a separate folder for your workspaces:
   /eclipse-workspaces

4. Create workspaces for your projects:
   /eclipse-workspaces/proj1
/eclipse-workspaces/proj2

Try this Using moment.js (Its quite easy to compute date operations in javascript)

firstDate.diff(secondDate, 'days', false);// true|false for fraction value

Result will give you number of days in integer.

A couple of methods that, if the char does not exists, return the original string.

This one cuts the string after the first occurrence of the pivot:

public static string truncateStringAfterChar(string input, char pivot){         
    int index = input.IndexOf(pivot);   
    if(index >= 0) {
        return input.Substring(index + 1);          
    }           
    return input;       
}

This one instead cuts the string after the last occurrence of the pivot:

public static string truncateStringAfterLastChar(string input, char pivot){         
    return input.Split(pivot).Last();   
}

Define the width as 960px, or whatever you prefer, and you're good to go!

#main {
 margin: 0 auto !important;
 float: none !important;
 text-align: center;
 width: 960px;
}

(I couldn't figure this out until I fixed the width, nothing else worked.)

For people wondering about a Servlet/JSP implementation here's how you go about doing it... I will be explaining uploadimage below also.

1) First make sure you have added the filebrowser and uploadimage variable to your config.js file. Make you also have the uploadimage and filebrowser folder inside the plugins folder too.

2) This part is where it tripped me up:

The Ckeditor website documentation says you need to use these two methods:

function getUrlParam( paramName ) {
    var reParam = new RegExp( '(?:[\?&]|&)' + paramName + '=([^&]+)', 'i' );
    var match = window.location.search.match( reParam );
    return ( match && match.length > 1 ) ? match[1] : null;
}
function returnFileUrl() {
    var funcNum = getUrlParam( 'CKEditorFuncNum' );
    var fileUrl = 'https://patiliyo.com/wp-content/uploads/2017/07/ruyada-kedi-gormek.jpg';
    window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl );
    window.close();
}

What they don't mention is that these methods have to be on a different page and not the page where you are clicking the browse server button from.

So if you have ckeditor initialized in page editor.jsp then you need to create a file browser (with basic html/css/javascript) in page filebrowser.jsp.

editor.jsp (all you need is this in your script tag) This page will open filebrowser.jsp in a mini window when you click on the browse server button.

CKEDITOR.replace( 'editor', {
    filebrowserBrowseUrl: '../filebrowser.jsp', //jsp page with jquery to call servlet and get image files to view
    filebrowserUploadUrl: '../UploadImage', //servlet

});

filebrowser.jsp (is the custom file browser you built which will contain the methods mentioned above)

<head>
<script src="../../ckeditor/ckeditor.js"></script>
</head>
<body>
<script>


function getUrlParam( paramName ) {
    var reParam = new RegExp( '(?:[\?&]|&)' + paramName + '=([^&]+)', 'i' );
    var match = window.location.search.match( reParam );
    return ( match && match.length > 1 ) ? match[1] : null;
}

function returnFileUrl() {
    var funcNum = getUrlParam( 'CKEditorFuncNum' );
var fileUrl = 'https://patiliyo.com/wp-content/uploads/2017/07/ruyada-kedi-gormek.jpg';
    window.opener.CKEDITOR.tools.callFunction( funcNum, fileUrl );
    window.close();
}


//when this window opens it will load all the images which you send from the FileBrowser Servlet. 
getImages();
function getImages(){
    $.get("../FileBrowser", function(responseJson) {    
        //do something with responseJson (like create <img> tags and update the src attributes) 
    });
}

   //you call this function and pass 'fileUrl' when user clicks on an image that you loaded into this window from a servlet
returnFileUrl();
</script>
</body>

3) The FileBrowser Servlet

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    Images i = new Images();
    List<ImageObject> images = i.getImages(); //get images from your database or some cloud service or whatever (easier if they are in a url ready format)
    String json = new Gson().toJson(images);
    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

4) UploadImage Servlet

Go back to your config.js file for ckeditor and add the following line:

//https://docs.ckeditor.com/ckeditor4/latest/guide/dev_file_upload.html
config.uploadUrl = '/UploadImage';

Then you can drag and drop files also:

   protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {


                Images i = new Images();

   //do whatever you usually do to upload your image to your server (in my case i uploaded to google cloud storage and saved the url in a database. 

   //Now this part is important. You need to return the response in json format. And it has to look like this:

//      https://docs.ckeditor.com/ckeditor4/latest/guide/dev_file_upload.html
//      response must be in this format:
//      {
//          "uploaded": 1,
//          "fileName": "example.png",
//          "url": "https://www.cats.com/example.png"
//      }

                    String image = "https://www.cats.com/example.png";
                        ImageObject objResponse = i.getCkEditorObjectResponse(image);
                        String json = new Gson().toJson(objResponse);
                        response.setContentType("application/json");
                        response.setCharacterEncoding("UTF-8");
                        response.getWriter().write(json);
                    }
                }

And that's all folks. Hope it helps someone.

I want to know how to check whether MySQL strict mode is on or off in localhost(xampp).

SHOW VARIABLES LIKE 'sql_mode';

If result has "STRICT_TRANS_TABLES", then it's ON. Otherwise, it's OFF.

If on then for what modes and how to off.

If off then how to on.

For Windows,

1. Go to C:\Program Files\MariaDB XX.X\data
2. Open the my.ini file.
3. *On the line with "sql_mode", modify the value to turn strict mode ON/OFF.
4. Save the file
5. **Restart the MySQL service
6. Run SHOW VARIABLES LIKE 'sql_mode' again to see if it worked;

*3.a. To turn it ON, add STRICT_TRANS_TABLES on that line like this: sql_mode=STRICT_TRANS_TABLES. *If there are other values already, add a comma after this then join with the rest of the value.

*3.b. To turn it OFF, simply remove STRICT_TRANS_TABLES from value. *Remove the additional comma too if there is one.

**6. To restart the MySQL service on your computer,

1. Open the Run command window (press WINDOWS + R button).
2. Type services.msc
3. Click OK
4. Right click on the Name MySQL
5. Click Restart

According to this article application/xml is preferred.

EDIT

I did a little follow-up on the article.

The author claims that the encoding declared in XML processing instructions, like:

<?xml version="1.0" encoding="UTF-8"?>

can be ignored when text/xml media type is used.

They support the thesis with the definition of text/* MIME type family specification in RFC 2046, specifically the following fragment:

4.1.2.  Charset Parameter

   A critical parameter that may be specified in the Content-Type field
   for "text/plain" data is the character set.  This is specified with a
   "charset" parameter, as in:

     Content-type: text/plain; charset=iso-8859-1

   Unlike some other parameter values, the values of the charset
   parameter are NOT case sensitive.  The default character set, which
   must be assumed in the absence of a charset parameter, is US-ASCII.

   The specification for any future subtypes of "text" must specify
   whether or not they will also utilize a "charset" parameter, and may
   possibly restrict its values as well.  For other subtypes of "text"
   than "text/plain", the semantics of the "charset" parameter should be
   defined to be identical to those specified here for "text/plain",
   i.e., the body consists entirely of characters in the given charset.
   In particular, definers of future "text" subtypes should pay close
   attention to the implications of multioctet character sets for their
   subtype definitions.

According to them, such difficulties can be avoided when using application/xml MIME type. Whether it's true or not, I wouldn't go as far as to avoid text/xml. IMHO, it's best just to follow the semantics of human-readability(non-readability) and always remember to specify the charset.

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

In the branch you would like to combine the commits on, run:

git rebase -i HEAD~(n number of commits back to review)

example:

git rebase -i HEAD~1

This will open the text editor and you must switch the 'pick' in front of each commit with 'squash' if you would like these commits to be merged together. From documentation:

p, pick = use commit

s, squash = use commit, but meld into previous commit

For example, if you are looking to merge all the commits into one, the 'pick' is the first commit you made and all future ones (placed below the first) should be set to 'squash'. If using vim, use :x in insert mode to save and exit the editor.

Then to continue the rebase:

git rebase --continue

For more on this and other ways to rewrite your commit history see this helpful post

use

console.log(variable)

and if you using google chrome open Console by using Ctrl+Shift+j

steps to change cookie expiration

step 1:Go to settings of Phpmyadmin

step 2:General

step 3:Login cookie validity

step 4:Update 1440 seconds default cookie expiration time with your new value

It depends on where you want to use those.

TextBoxBase-derived controls already implement those shortcuts. If you want to use custom keyboard shortcuts you should take a look on Commands and Input gestures. Here is a small tutorial from Switch on the Code: WPF Tutorial - Command Bindings and Custom Commands

Client Side

Data needs to be grouped in an object array as payload - Indata:

var Indata = {'product': $scope.product, 'product2': $scope.product2 };

Pass the payload through $http.post as the second argument:

$http.post("http://localhost:53263/api/Products/", Indata).then(function (data, status, headers, config) { 
    alert("success"); 
},function (data, status, headers, config) { 
    alert("error"); 
});

Server Side

Create a Data Transfer Object(DTO) class as such:

public class ExampleRequest {
   public string product {get; set;};
   public string product2 {get; set;};
}

The class below accepts DTO with the same property names which the payload is carrying.

public void Post(ExampleRequest request)
{
    var productRepository = new ProductRepository();
    var newProduct = productRepository.Save(request.product);
}

In above class, request contains 2 properties with values of product and product2

This did it for me simply and perfectly.

Excellent explanation by Scott Robinson

From image to base64 string

let buff = fs.readFileSync('stack-abuse-logo.png');
let base64data = buff.toString('base64');

From base64 string to image

let buff = new Buffer(data, 'base64');
fs.writeFileSync('stack-abuse-logo-out.png', buff);

There may be an elegant built-in function (but I haven't found it yet). You could write one:

# reorder columns
def set_column_sequence(dataframe, seq, front=True):
    '''Takes a dataframe and a subsequence of its columns,
       returns dataframe with seq as first columns if "front" is True,
       and seq as last columns if "front" is False.
    '''
    cols = seq[:] # copy so we don't mutate seq
    for x in dataframe.columns:
        if x not in cols:
            if front: #we want "seq" to be in the front
                #so append current column to the end of the list
                cols.append(x)
            else:
                #we want "seq" to be last, so insert this
                #column in the front of the new column list
                #"cols" we are building:
                cols.insert(0, x)
return dataframe[cols]

For your example: set_column_sequence(df, ['x','y']) would return the desired output.

If you want the seq at the end of the DataFrame instead simply pass in "front=False".

You can put all into linear layout. That is, create linear layout and it will have 2 childs, scrollview and another linear layout. Give them layout weights and here you go :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"

            android:ems="10"
            android:hint="@string/addTaskCurrentStatus"
            android:inputType="numberDecimal" />


    </LinearLayout>
</ScrollView>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:orientation="vertical" android:layout_weight="0.2">

The window is the first thing that gets loaded into the browser. This window object has the majority of the properties like length, innerWidth, innerHeight, name, if it has been closed, its parents, and more.

The document object is your html, aspx, php, or other document that will be loaded into the browser. The document actually gets loaded inside the window object and has properties available to it like title, URL, cookie, etc. What does this really mean? That means if you want to access a property for the window it is window.property, if it is document it is window.document.property which is also available in short as document.property.

C++20 std::rotl and std::rotr

It has arrived! http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0553r4.html and should add it to the <bit> header.

cppreference says that the usage will be like:

#include <bit>
#include <bitset>
#include <cstdint>
#include <iostream>

int main()
{
    std::uint8_t i = 0b00011101;
    std::cout << "i          = " << std::bitset<8>(i) << '\n';
    std::cout << "rotl(i,0)  = " << std::bitset<8>(std::rotl(i,0)) << '\n';
    std::cout << "rotl(i,1)  = " << std::bitset<8>(std::rotl(i,1)) << '\n';
    std::cout << "rotl(i,4)  = " << std::bitset<8>(std::rotl(i,4)) << '\n';
    std::cout << "rotl(i,9)  = " << std::bitset<8>(std::rotl(i,9)) << '\n';
    std::cout << "rotl(i,-1) = " << std::bitset<8>(std::rotl(i,-1)) << '\n';
}

giving output:

i          = 00011101
rotl(i,0)  = 00011101
rotl(i,1)  = 00111010
rotl(i,4)  = 11010001
rotl(i,9)  = 00111010
rotl(i,-1) = 10001110

I'll give it a try when support arrives to GCC, GCC 9.1.0 with g++-9 -std=c++2a still doesn't support it.

The proposal says:

Header:

namespace std {
  // 25.5.5, rotating   
  template<class T>
    [[nodiscard]] constexpr T rotl(T x, int s) noexcept;
  template<class T>
    [[nodiscard]] constexpr T rotr(T x, int s) noexcept;

and:

25.5.5 Rotating [bitops.rot]

In the following descriptions, let N denote std::numeric_limits<T>::digits.

template<class T>
  [[nodiscard]] constexpr T rotl(T x, int s) noexcept;

Constraints: T is an unsigned integer type (3.9.1 [basic.fundamental]).

Let r be s % N.

Returns: If r is 0, x; if r is positive, (x << r) | (x >> (N - r)); if r is negative, rotr(x, -r).

template<class T>
  [[nodiscard]] constexpr T rotr(T x, int s) noexcept;

Constraints: T is an unsigned integer type (3.9.1 [basic.fundamental]). Let r be s % N.

Returns: If r is 0, x; if r is positive, (x >> r) | (x << (N - r)); if r is negative, rotl(x, -r).

A std::popcount was also added to count the number of 1 bits: How to count the number of set bits in a 32-bit integer?

You should work with padding on the inner container rather than with margin. Try this!

HTML

<div class="row info-panel">
    <div class="col-md-4" id="server_1">
       <div class="server-action-menu">
           Server 1
       </div>
   </div>
</div>

CSS

.server-action-menu {
    background-color: transparent;
    background-image: linear-gradient(to bottom, rgba(30, 87, 153, 0.2) 0%, rgba(125, 185, 232, 0) 100%);
    background-repeat: repeat;
    border-radius:10px;
    padding: 5px;
}

Java and Kotlin runs on Java Virtual Machine (JVM).

Converting a Kotlin file to Java file involves two steps i.e. compiling the Kotlin code to the JVM bytecode and then decompile the bytecode to the Java code.

Steps to convert your Kotlin source file to Java source file:

1. Open your Kotlin project in the Android Studio.
2. Then navigate to Tools -> Kotlin -> Show Kotlin Bytecode.

3. You will get the bytecode of your Kotin file.
4. Now click on the Decompile button to get your Java code from the bytecode

select * from xyz where (1=(CASE WHEN @AnnualFeeType = 'All' THEN 1 ELSE 0 END) OR AnnualFeeType = @AnnualFeeType)

You could also use the argwhere function in Numpy. For example:

i) Find the first "l" in "helloworld":

import numpy as np
l = list("helloworld") # Create list
i = np.argwhere(np.array(l)=="l") # i = array([[2],[3],[8]])
index_of_first = i.min()

ii) Find first random number > 0.1

import numpy as np
r = np.random.rand(50) # Create random numbers
i = np.argwhere(r>0.1)
index_of_first = i.min()

iii) Find the last random number > 0.1

import numpy as np
r = np.random.rand(50) # Create random numbers
i = np.argwhere(r>0.1)
index_of_last = i.max()

top refers to the window object which contains all the current frames ( father of the rest of the windows ). window is the current window.

http://www.howtocreate.co.uk/tutorials/javascript/browserinspecific

so top.location.href can contain the "master" page link containing all the frames, while window.location.href just contains the "current" page link.

The window binding refers to a built-in object provided by the browser. It represents the browser window that contains the document. Calling its addEventListener method registers the second argument (callback function) to be called whenever the event described by its first argument occurs.

<p>Some paragraph.</p>
<script>
  window.addEventListener("click", () => {
    console.log("Test");
  });
</script>

Following points should be noted before select window or document to addEventListners

1. Most of the events are same for window or document but some events like resize, and other events related to loading, unloading, and opening/closing should all be set on the window.
2. Since window has the document it is good practice to use document to handle (if it can handle) since event will hit document first.
3. Internet Explorer doesn't respond to many events registered on the window,so you will need to use document for registering event.

in this situation, you would grab the element by its id using getElementById and then just use .src

var youtubeimgsrc = document.getElementById("youtubeimg").src;

My solution is to define a merge function. It's not sophisticated and just cost one line. Here's the code in Python 3.

from functools import reduce
from operator import or_

def merge(*dicts):
    return { k: reduce(lambda d, x: x.get(k, d), dicts, None) for k in reduce(or_, map(lambda x: x.keys(), dicts), set()) }

Tests

>>> d = {0: 0, 1: 1, 2: 4, 3: 9, 4: 16}
>>> d_letters = {0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d, d_letters)
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d_letters, d)
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d)

It works for arbitrary number of dictionary arguments. Were there any duplicate keys in those dictionary, the key from the rightmost dictionary in the argument list wins.

Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>

bool === tool ? bool : tool

if you want the value to hold true if tool (another boolean) has the same value

It's difficult to answer the question without 2 other concepts: iterable and iterator protocol.

1. What is difference between iterator and iterable? Conceptually you iterate over iterable with the help of corresponding iterator. There are a few differences that can help to distinguish iterator and iterable in practice:
   • One difference is that iterator has __next__ method, iterable does not.
   • Another difference - both of them contain __iter__ method. In case of iterable it returns the corresponding iterator. In case of iterator it returns itself. This can help to distinguish iterator and iterable in practice.

>>> x = [1, 2, 3]
>>> dir(x) 
[... __iter__ ...]
>>> x_iter = iter(x)
>>> dir(x_iter)
[... __iter__ ... __next__ ...]
>>> type(x_iter)
list_iterator

2. What are iterables in python? list, string, range etc. What are iterators? enumerate, zip, reversed etc. We may check this using the approach above. It's kind of confusing. Probably it would be easier if we have only one type. Is there any difference between range and zip? One of the reasons to do this - range has a lot of additional functionality - we may index it or check if it contains some number etc. (see details here).

3. How can we create an iterator ourselves? Theoretically we may implement Iterator Protocol (see here). We need to write __next__ and __iter__ methods and raise StopIteration exception and so on (see Alex Martelli's answer for an example and possible motivation, see also here). But in practice we use generators. It seems to be by far the main method to create iterators in python.

I can give you a few more interesting examples that show somewhat confusing usage of those concepts in practice:

• in keras we have tf.keras.preprocessing.image.ImageDataGenerator; this class doesn't have __next__ and __iter__ methods; so it's not an iterator (or generator);
• if you call its flow_from_dataframe() method you'll get DataFrameIterator that has those methods; but it doesn't implement StopIteration (which is not common in build-in iterators in python); in documentation we may read that "A DataFrameIterator yielding tuples of (x, y)" - again confusing usage of terminology;
• we also have Sequence class in keras and that's custom implementation of a generator functionality (regular generators are not suitable for multithreading) but it doesn't implement __next__ and __iter__, rather it's a wrapper around generators (it uses yield statement);

If you need to update user information for a specific user ID "x",

1. you need to create a dbManager class that will initialise the database in its constructor and acts as a mediator between your viewModel and DAO, and also .

2. The ViewModel will initialize an instance of dbManager to access the database. The code should look like this:

      @Entity
       class User{
       @PrimaryKey
       String userId;
       String username;
       }
   
       Interface UserDao{
       //forUpdate
       @Update
       void updateUser(User user)
       }
   
       Class DbManager{
       //AppDatabase gets the static object o roomDatabase.
       AppDatabase appDatabase;
       UserDao userDao;
       public DbManager(Application application ){
       appDatabase = AppDatabase.getInstance(application);
   
       //getUserDao is and abstract method of type UserDao declared in AppDatabase //class
       userDao = appDatabase.getUserDao();
       } 
   
       public void updateUser(User user, boolean isUpdate){
       new InsertUpdateUserAsyncTask(userDao,isUpdate).execute(user);
       }
   
   
   
       public static class InsertUpdateUserAsyncTask extends AsyncTask<User, Void, Void> {
   
   
        private UserDao userDAO;
        private boolean isInsert;
   
        public InsertUpdateBrandAsyncTask(BrandDAO userDAO, boolean isInsert) {
          this. userDAO = userDAO;
          this.isInsert = isInsert;
        }
   
        @Override
        protected Void doInBackground(User... users) {
          if (isInsert)
       userDAO.insertBrand(brandEntities[0]);
          else
       //for update
       userDAO.updateBrand(users[0]);
       //try {
       //  Thread.sleep(1000);
       //} catch (InterruptedException e) {
       //  e.printStackTrace();
       //}
          return null;
        }
         }
       }
   
        Class UserViewModel{
        DbManager dbManager;
        public UserViewModel(Application application){
        dbmanager = new DbMnager(application);
        }
   
        public void updateUser(User user, boolean isUpdate){
        dbmanager.updateUser(user,isUpdate);
        }
   
        }
   
   
   
   
   Now in your activity or fragment initialise your UserViewModel like this:
   
   UserViewModel userViewModel = ViewModelProviders.of(this).get(UserViewModel.class);
   

   Then just update your user item this way, suppose your userId is 1122 and userName is "xyz" which has to be changed to "zyx".

   Get an userItem of id 1122 User object

User user = new user();
 if(user.getUserId() == 1122){
   user.setuserName("zyx");
   userViewModel.updateUser(user);
 }

This is a raw code, hope it helps you.

Happy coding

You could also use File.Copy to copy and File.Move to rename it afterwords.

// Copy the file (specify true or false to overwrite or not overwrite the destination file if it exists.
File.Copy(mySourceFileAndPath, myDestinationFileAndPath, [true | false]);

// EDIT: as "astander" notes correctly, this step is not necessary, as File.Copy can rename already...
//       However, this code could be adapted to rename the original file after copying
// Rename the file if the destination file doesn't exist. Throw exception otherwise
//if (!File.Exists(myRenamedDestinationFileAndPath))
//    File.Move(myDestinationFileAndPath, myRenamedDestinationFileAndPath);
//else
//    throw new IOException("Failed to rename file after copying, because destination file exists!");

EDIT
Commented out the "rename" code, because File.Copy can already copy and rename in one step, as astander noted correctly in the comments.

However, the rename code could be adapted if the OP desired to rename the source file after it has been copied to a new location.

If you should need to replace the handle with something else entirely, rather than just restyling it:

You can specify custom handle elements by creating and appending the elements and adding the ui-slider-handle class before initialization.

Working Example

$('.slider').append('<div class="my-handle ui-slider-handle"><svg height="18" width="14"><path d="M13,9 5,1 A 10,10 0, 0, 0, 5,17z"/></svg></div>');_x000D_
_x000D_
$('.slider').slider({_x000D_
  range: "min",_x000D_
  value: 10_x000D_
});

.slider .ui-state-default {_x000D_
  background: none;_x000D_
}_x000D_
.slider.ui-slider .ui-slider-handle {_x000D_
  width: 14px;_x000D_
  height: 18px;_x000D_
  margin-left: -5px;_x000D_
  top: -4px;_x000D_
  border: none;_x000D_
  background: none;_x000D_
}_x000D_
.slider {_x000D_
  height: 10px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_

In my work environment root, .babelrc file was not there. However, following entry in package.json solved the issue.

"babel": {
"presets": [
  "@babel/preset-env",
  "@babel/preset-react"
],
"plugins": [
  "@babel/plugin-proposal-class-properties"
]}

Note: Don't forget to exit the console and reopen before executing the npm or yarn commands.

If you're using the validation plugin you can use:

jQuery.validator.format("{0} {1}", "cool", "formatting") = 'cool formatting'

How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

Ugliest interface possible, but does what you ask. Zero allocations.

http://zserge.com/jsmn.html Another zero-allocation approach.

The solutions posted above all do dynamic memory allocation, hence will be inevitably end up slower at some point, depending on the data structure - and will be dangerous to include in a heap constrained environment like an embedded system.

Benchmarks of vjson, rapidjson and sajson here : http://chadaustin.me/2013/01/json-parser-benchmarking/ if you are interested in that sort of thing.

And to answer your "writer" part of the question i doubt that you could beat an efficient

printf("{%s:%s}",name,value)

implementation with any library - assuming your printf/sprintf implementation itself is lightweight of course.

EDIT: actually let me take that back, RapidJson allows on-stack allocation only through its MemoryPoolAllocator and actually makes this a default for its GenericReader. I havent done the comparison but i would expect it to be more robust than anything else listed here. It also doesnt have any dependencies, and it doesnt throw exceptions which probably makes it ultimately suitable for embedded. Fully header based lib so, easy to include anywhere.

if you have number of columns in your database table more than number of columns in your csv you can proceed like this:

LOAD DATA LOCAL INFILE 'pathOfFile.csv'
INTO TABLE youTable 
CHARACTER SET latin1 FIELDS TERMINATED BY ';' #you can use ',' if you have comma separated
OPTIONALLY ENCLOSED BY '"' 
ESCAPED BY '\\' 
LINES TERMINATED BY '\r\n'
(yourcolumn,yourcolumn2,yourcolumn3,yourcolumn4,...);

As mentioned before, the easiest way it to use rotation available since API 11:

android:rotation="90"    // in XML layout

view.rotation = 90f      // programatically

You can also change pivot of rotation, which is by default set to center of the view. This needs to be changed programatically:

// top left
view.pivotX = 0f
view.pivotY = 0f

// bottom right
view.pivotX = width.toFloat()
view.pivotY = height.toFloat()

...

In Activity's onCreate() or Fragment's onCreateView(...) width and height are equal to 0, because the view wasn't measured yet. You can access it simply by using doOnPreDraw extension from Android KTX, i.e.:

view.apply {
    doOnPreDraw {
        pivotX = width.toFloat()
        pivotY = height.toFloat()
    }
}

My solution, using if..else statement. It is always a good practice if you want to avoid unnecessary frustrations, to check that your variable exists and is set. Otherwise, provide a backup image in case; You can also specify multiple style properties, like background-position: center, etc.

<div [ngStyle]="{'background-image': this.photo ? 'url(' + this.photo + ')' : 'https://placehold.it/70x70', 'background-position': 'center' }"></div>

select * from table where id not in (select id from table limit 10)

where id be the key in your table.

I encountered the same issue few days ago. My audio MediaPlayer works fine on devices with high processing power, but for slow devices, the media player just did not play some time and from LogCat it had many complain about called in wrong state. So I resolved it by calling putting the call to start(), pause(),... in onPrepared() method of OnPreparedListener() as below:

mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    ........
                    mediaPlayer.start();
                    ....
                    songControlBtn.setOnClickListener(new OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            if (mediaPlayer.isPlaying()) {
                                mediaPlayer.pause();

                            } else {
                                mediaPlayer.start();

                            }
                        }
                    });

                    mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
                        @Override
                        public void onCompletion(MediaPlayer mp) {
                            ............

                        }
                    });
                }
            });

Also try to release any media player that you do not need any more. For example, if you do not want to play the audio or video on background then you should call mediaPlayer.release() in onPause().

You should use the OpenFileDialog class like this

Dim fd As OpenFileDialog = New OpenFileDialog() 
Dim strFileName As String

fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True

If fd.ShowDialog() = DialogResult.OK Then
   strFileName = fd.FileName
End If

Then you can use the File class.

Most probably the issue of ImagePullBackOff is due to either the image not being present or issue with the pod YAML file.

What I will do is this

kubectl get pod -n $namespace $POD_NAME --export > pod.yaml | kubectl -f apply -

I would also see the pod.yaml to see the why the earlier pod didn't work

To add to the answers above, while print can only take one parameter, it will allow for concatenation of multiple values, ie:

$count = 5;

print "This is " . $count . " values in " . $count/5 . " parameter";

This is 5 values in 1 parameter

I've been struggling with this issue and I've tried numerous "solutions".

However, in the end, the only one that worked and it actually took a few seconds to do it was to: delete and add back new server instance!

Basically, I right clicked on my Tomcat server in Eclipse under Servers and deleted it. Next, I've added a new Tomcat server. Cleaned and redeployed the application and I got rid of this error.

If you want auto-indent just like Emacs does it on TAB, i.e. indent the current line and move the cursor to the first non-whitespace character, do this:

1. Go to Tools -> Options -> Editor -> Macros
2. Create a new macro and call it something like "tabindent"

3. Insert the following macro code:

   reindent-line caret-line-first-column caret-begin-line

4. Click "Set Shortcut" and press TAB

I spent the last day trying to figure out why I was getting the following error. I am running Ubuntu 14.04.

The Problem:
I noticed that my PHP-CLI version was running php7.0 but php_info() (the web version) was displaying php 5.5.9. Even though php_info() said pdo was enabled, using the command line (CLI) wasn't recognizing the pdo_mysql command. It turns out that mysql was enabled for my old version but not the CLI version. All I did was install mysql for php7.0 and it was able to work.

This is what worked:

To check the version:

php -v

To install mysql for php7.0

sudo apt-get install php7.0-mysql

1) make sure your CLI version is the same as your web version
2) If they are different, make sure your CLI version has the mysql plug-in since it doesn't come with it as a default.

I had a similar problem, and the solution for me was quite different from what the other users posted.

The problem with me was related to the project I was working last year, which required a certain proxy on maven settings (located at <path to maven folder>\maven\conf\settings.xml and C:\Users\<my user>\.m2\settings.xml). The proxy was blocking the download of required external packages.

The solution was to put back the original file (settings.xml) on those places. Once things were restored, I was able to download the packages and everything worked.

I tried a few of these things until I got one to work in both Firefox and IE. This is what I came up with.

$("#my-Select").val($("#my-Select" + " option").filter(function() { return this.text == myText }).val());

another way of writing it in a more readable fasion:

var valofText = $("#my-Select" + " option").filter(function() {
    return this.text == myText
}).val();
$(ElementID).val(valofText);

Pseudocode:

$("#my-Select").val( getValOfText( myText ) );

Async Arrow function syntax with parameters

const myFunction = async (a, b, c) => {
   // Code here
}

For others who use spring-boot, java based configuration,

I set the schema value in application.properties

spring.jpa.properties.hibernate.dialect=...
