I have the same error : ERROR FIX !!!!

I use 'react-router-redux' v4 but she's bad.. After npm install react-router-redux@next I'm on "react-router-redux": "^5.0.0-alpha.9",

AND IT'S WORK

I understand you intention well, I use buffers exclusively too, and occasionally do split if needed.

below is excerpt of my .vimrc

" disable macro, since not used in 90+% use cases
map q <Nop>
" q,  close/hide current window, or quit vim if no other window
nnoremap q :if winnr('$') > 1 \|hide\|else\|silent! exec 'q'\|endif<CR>
" qo, close all other window    -- 'o' stands for 'only'
nnoremap qo :only<CR>
set hidden
set timeout
set timeoutlen=200   " let vim wait less for your typing!

Which fits my workflow quite well

If q was pressed

• hide current window if multiple window open, else try to quit vim.

if qo was pressed,

• close all other window, no effect if only one window.

Of course, you can wrap that messy part into a function, eg

func! Hide_cur_window_or_quit_vim()
    if winnr('$') > 1
        hide
    else
        silent! exec 'q'
    endif
endfunc
nnoremap q :call Hide_cur_window_or_quit_vim()<CR>

Sidenote: I remap q, since I do not use macro for editing, instead use :s, :g, :v, and external text processing command if needed, eg, :'{,'}!awk 'some_programm', or use :norm! normal-command-here.

If you are using individual jquery files or a custom jquery download either way make sure you also have jquery.ui.position.js added to your page.

Perfect answer for your question can be found on MYSQL site itself.refer their manual(without using PHP)

http://forums.mysql.com/read.php?20,17671,27914

According to them use LONGBLOB datatype. with that you can only store images less than 1MB only by default,although it can be changed by editing server config file.i would also recommend using MySQL workBench for ease of database management

I know this is kind of late but this plugin should work. http://remysharp.com/2009/01/26/element-in-view-event-plugin/

$('p.inview').bind('inview', function (event, visible) {
if (visible) {
  $(this).text('You can see me!');
} else {
  $(this).text('Hidden again');
}

you can simply do this..

 <img src={"http://img.example.com/test/" + this.props.url +"/1.jpg"}/>

Try this..

Dim S As String
S = "RAJAN"
Dim answer As Char
answer = S.Substring(0, 1)

 protected void Application_Start(object sender, EventArgs e)
 {
     string path = Server.MapPath("/");
     //or 
     string path2 = Server.MapPath("~");
     //depends on your application needs

 }

This answer will help in case, If you are working with Data Bases then mostly take the help of try-catch block statement, which will help and guide you with your code. Here i am showing you that how to insert some values in Data Base with a Button Click Event.

I just came across the same issue while trying to query a MySQL Database from Pentaho.

Error connecting to database [Local MySQL DB] : org.pentaho.di.core.exception.KettleDatabaseException: Error occured while trying to connect to the database

Exception while loading class org.gjt.mm.mysql.Driver

Expanding post by @user979331 the solution is:

1. Download the MySQL Java Connector / Driver that is compatible with your kettle version
2. Unzip the zip file (in my case it was mysql-connector-java-5.1.31.zip)

3. copy the .jar file (mysql-connector-java-5.1.31-bin.jar) and paste it in your Lib folder:

   PC: C:\Program Files\pentaho\design-tools\data-integration\lib

   Mac: /Applications/data-integration/lib

Restart Pentaho (Data Integration) and re-test the MySQL Connection.

Additional interesting replies from others that could also help:

• think to download the good JDBC driver version, compatible with your PDI version: https://help.pentaho.com/Documentation/8.1/Setup/JDBC_Drivers_Reference#MY_SQL
• take the zip version ("platform independant") to extract the jar file
• take into lib folder
• see also proper way to handle it proposed by Ryan Tuck

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

You can handle WM_NCPAINT message of TextBox and draw a border on the non-client area of control if the control has focus. You can use any color to draw border:

using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public class ExTextBox : TextBox
{
    [DllImport("user32")]
    private static extern IntPtr GetWindowDC(IntPtr hwnd);
    private const int WM_NCPAINT = 0x85;
    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
        if (m.Msg == WM_NCPAINT && this.Focused)
        {
            var dc = GetWindowDC(Handle);
            using (Graphics g = Graphics.FromHdc(dc))
            {
                g.DrawRectangle(Pens.Red, 0, 0, Width - 1, Height - 1);
            }
        }
    }
}

Result

The painting of borders while the control is focused is completely flicker-free:

BorderColor property for TextBox

In the current post I just change the border color on focus. You can also add a BorderColor property to the control. Then you can change border-color based on your requirement at design-time or run-time. I've posted a more completed version of TextBox which has BorderColor property: in the following post:

• BorderColor property for TextBox

As a one liner: name += std::to_string(age);

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

$ man memset

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

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

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

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

The answer here is Oracle only. Here's a bit more sophisticated answer in all SQL:

Who has the best overall homework result (maximum sum of homework points)?

SELECT FIRST, LAST, SUM(POINTS) AS TOTAL
FROM STUDENTS S, RESULTS R
WHERE S.SID = R.SID AND R.CAT = 'H'
GROUP BY S.SID, FIRST, LAST
HAVING SUM(POINTS) >= ALL (SELECT SUM (POINTS)
FROM RESULTS
WHERE CAT = 'H'
GROUP BY SID)

And a more difficult example, which need some explanation, for which I don't have time atm:

Give the book (ISBN and title) that is most popular in 2008, i.e., which is borrowed most often in 2008.

SELECT X.ISBN, X.title, X.loans
FROM (SELECT Book.ISBN, Book.title, count(Loan.dateTimeOut) AS loans
FROM CatalogEntry Book
LEFT JOIN BookOnShelf Copy
ON Book.bookId = Copy.bookId
LEFT JOIN (SELECT * FROM Loan WHERE YEAR(Loan.dateTimeOut) = 2008) Loan 
ON Copy.copyId = Loan.copyId
GROUP BY Book.title) X
HAVING loans >= ALL (SELECT count(Loan.dateTimeOut) AS loans
FROM CatalogEntry Book
LEFT JOIN BookOnShelf Copy
ON Book.bookId = Copy.bookId
LEFT JOIN (SELECT * FROM Loan WHERE YEAR(Loan.dateTimeOut) = 2008) Loan 
ON Copy.copyId = Loan.copyId
GROUP BY Book.title);

Hope this helps (anyone).. :)

One thing that is not covered here is that it depends if we compare string to c string, c string to string or string to string.

A major difference is that for comparing two strings size equality is checked before doing the compare and that makes the == operator faster than a compare.

here is the compare as i see it on g++ Debian 7

// operator ==
  /**
   *  @brief  Test equivalence of two strings.
   *  @param __lhs  First string.
   *  @param __rhs  Second string.
   *  @return  True if @a __lhs.compare(@a __rhs) == 0.  False otherwise.
   */
  template<typename _CharT, typename _Traits, typename _Alloc>
    inline bool
    operator==(const basic_string<_CharT, _Traits, _Alloc>& __lhs,
           const basic_string<_CharT, _Traits, _Alloc>& __rhs)
    { return __lhs.compare(__rhs) == 0; }

  template<typename _CharT>
    inline
    typename __gnu_cxx::__enable_if<__is_char<_CharT>::__value, bool>::__type
    operator==(const basic_string<_CharT>& __lhs,
           const basic_string<_CharT>& __rhs)
    { return (__lhs.size() == __rhs.size()
          && !std::char_traits<_CharT>::compare(__lhs.data(), __rhs.data(),
                            __lhs.size())); }

  /**
   *  @brief  Test equivalence of C string and string.
   *  @param __lhs  C string.
   *  @param __rhs  String.
   *  @return  True if @a __rhs.compare(@a __lhs) == 0.  False otherwise.
   */
  template<typename _CharT, typename _Traits, typename _Alloc>
    inline bool
    operator==(const _CharT* __lhs,
           const basic_string<_CharT, _Traits, _Alloc>& __rhs)
    { return __rhs.compare(__lhs) == 0; }

  /**

   *  @param __lhs  String.
   *  @param __rhs  C string.

   */
  template<typename _CharT, typename _Traits, typename _Alloc>

From matplotlib 3.1 onwards you may use ax.secondary_xaxis

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(1,13, num=301)
y = (np.sin(x)+1.01)*3000

# Define function and its inverse
f = lambda x: 1/(1+x)
g = lambda x: 1/x-1

fig, ax = plt.subplots()
ax.semilogy(x, y, label='DM')

ax2 = ax.secondary_xaxis("top", functions=(f,g))

ax2.set_xlabel("1/(x+1)")
ax.set_xlabel("x")
plt.show()

I ran into this problem the other day on my Windows 7 machine. Problem wasn't my path, but I had to use escaped forward slashes instead of backslashes like this:

"scripts": {
    "script": ".\\bin\\script.sh"
}

You can simply write

Worksheets.Copy

in lieu of running a cycle. By default the worksheet collection is reproduced in a new workbook.

It is proven to function in 2010 version of XL.

The difference is quite simple:

OLTP (Online Transaction Processing)

OLTP is a class of information systems that facilitate and manage transaction-oriented applications. OLTP has also been used to refer to processing in which the system responds immediately to user requests. Online transaction processing applications are high throughput and insert or update-intensive in database management. Some examples of OLTP systems include order entry, retail sales, and financial transaction systems.

OLAP (Online Analytical Processing)

OLAP is part of the broader category of business intelligence, which also encompasses relational database, report writing and data mining. Typical applications of OLAP include business reporting for sales, marketing, management reporting, business process management (BPM), budgeting and forecasting, financial reporting and similar areas.

See more details OLTP and OLAP

sleep doesn't work because the display can only be updated after your main thread returns to the system. NSTimer is the way to go. To do this, you need to implement methods which will be called by the timer to change the buttons. An example:

- (void)button_circleBusy:(id)sender {
    firstButton.enabled = NO;
    // 60 milliseconds is .06 seconds
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];
}
- (void)goToSecondButton:(id)sender {
    firstButton.enabled = YES;
    secondButton.enabled = NO;
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToThirdButton:) userInfo:nil repeats:NO];
}
...

you should use bootstrap v.4

<div class="form-group row">
    <div class="col-md-6">
        <input type="button" class="btn form-control" id="btn1">
    </div>
    <div class="col-md-6">
        <input type="button" class="btn form-control" id="btn2">
    </div>
</div>

Here is the best way I found for Python 2:

def inplace_change(file,old,new):
        fin = open(file, "rt")
        data = fin.read()
        data = data.replace(old, new)
        fin.close()

        fin = open(file, "wt")
        fin.write(data)
        fin.close()

An example:

inplace_change('/var/www/html/info.txt','youtub','youtube')

This isn't a very beautiful answer, but it's what I use to create zero-length vectors:

0[-1]     # numeric
""[-1]    # character
TRUE[-1]  # logical
0L[-1]    # integer

A literal is a vector of length 1, and [-1] removes the first element (the only element in this case) from the vector, leaving a vector with zero elements.

As a bonus, if you want a single NA of the respective type:

0[NA]     # numeric
""[NA]    # character
TRUE[NA]  # logical
0L[NA]    # integer

Instead of

css=#container

use

css=div.container:nth-of-type(1),css=div.container:nth-of-type(2)

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

   </tbody>
</table>

Post the string with raw JSON, and do not forget the double quotation marks!

In my case the symbols I create (Tax1, Tax2, etc.) already had values but I wanted to use a loop and assign the symbols to another variable. So the above two answers gave me a way to accomplish this. This may be helpful in answering your question as the assignment of a value can take place anytime later.

output=NULL
for(i in 1:8){
   Tax=eval(as.symbol(paste("Tax",i,sep="")))
   L_Data1=L_Data_all[which(L_Data_all$Taxon==Tax[1] | L_Data_all$Taxon==Tax[2] | L_Data_all$Taxon==Tax[3] | L_Data_all$Taxon==Tax[4] | L_Data_all$Taxon==Tax[5]),]
   L_Data=L_Data1$Length[which(L_Data1$Station==Plant[1] | L_Data1$Station==Plant[2])]
   h=hist(L_Data,breaks=breaks,plot=FALSE)
   output=cbind(output,h$counts)
}

I had forgot where the sdk location was installed to so what I did was open Android Studio and selected Settings then used the following submenu

Current 1/1/2017:Tools -> SDK Manager

outdate: Appearance & Behavior -> System Settings -> Android SDK

There the sdk location was listed as Android SDK Location

I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:

In global.asax:

public class MvcApplication : HttpApplication
{
    protected void Application_EndRequest()
    {
        if (Context.Response.StatusCode == 404)
        {
            Response.Clear();

            var rd = new RouteData();
            rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
            rd.Values["controller"] = "Errors";
            rd.Values["action"] = "NotFound";

            IController c = new ErrorsController();
            c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
        }
    }
}

ErrorsController:

public sealed class ErrorsController : Controller
{
    public ActionResult NotFound()
    {
        ActionResult result;

        object model = Request.Url.PathAndQuery;

        if (!Request.IsAjaxRequest())
            result = View(model);
        else
            result = PartialView("_NotFound", model);

        return result;
    }
}

Edit:

If you're using IoC (e.g. AutoFac), you should create your controller using:

var rc = new RequestContext(new HttpContextWrapper(Context), rd);
var c = ControllerBuilder.Current.GetControllerFactory().CreateController(rc, "Errors");
c.Execute(rc);

Instead of

IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));

(Optional)

Explanation:

There are 6 scenarios that I can think of where an ASP.NET MVC3 apps can generate 404s.

Generated by ASP.NET:

• Scenario 1: URL does not match a route in the route table.

Generated by ASP.NET MVC:

• Scenario 2: URL matches a route, but specifies a controller that doesn't exist.

• Scenario 3: URL matches a route, but specifies an action that doesn't exist.

Manually generated:

• Scenario 4: An action returns an HttpNotFoundResult by using the method HttpNotFound().

• Scenario 5: An action throws an HttpException with the status code 404.

• Scenario 6: An actions manually modifies the Response.StatusCode property to 404.

Objectives

• (A) Show a custom 404 error page to the user.

• (B) Maintain the 404 status code on the client response (specially important for SEO).

• (C) Send the response directly, without involving a 302 redirection.

Solution Attempt: Custom Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customErrors>
</system.web>

Problems with this solution:

• Does not comply with objective (A) in scenarios (1), (4), (6).
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C).

Solution Attempt: HTTP Errors

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (A) in scenarios (2), (3), (5).
• Does not comply with objective (B) automatically. It must be programmed manually.

Solution Attempt: HTTP Errors with Replace

<system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• It obscures application level http exceptions. E.g. can't use customErrors section, System.Web.Mvc.HandleErrorAttribute, etc. It can't only show generic error pages.

Solution Attempt customErrors and HTTP Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customError>
</system.web>

and

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C) in scenarios (2), (3), (5).

People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the scenarios without the complexity of using an external library.

According to this Egnyte article, Passive FTP is supported from Windows 8.1 onwards.

The Registry key:

"HKEY_CURRENT_USER\Software\Microsoft\FTP\Use PASV"

should be set with the value: yes

If you don't like poking around in the Registry, do the following:

1. Press WinKey+R to open the Run dialog.
2. Type inetcpl.cpl and press Enter. The Internet Options dialog will open.
3. Click on the Advanced tab.
4. Make your way down to the Browsing secction of the tree view, and ensure the Use Passive FTP item is set to on.
5. Click on the OK button.

Every time you use ftp.exe, remember to pass the

quote pasv

command immediately after logging in to a remote host.

PS: Grant ftp.exe access to private networks if your Firewall complains.

See Python 3.x format string syntax:

IDLE 3.5.1   
numbers = ['23.23', '.1233', '1', '4.223', '9887.2']

for x in numbers:  
    print('{0: >#016.4f}'. format(float(x)))  

     23.2300
      0.1233
      1.0000
      4.2230
   9887.2000

First check a Launch Activity is set in your 'manifest.xml' file has:

<activity android:name=".{activityName}">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

If this is set correctly, next check your run/debug configuration is set to 'App',

If the 'App' configuration is missing - you will need to add it by first selecting 'Edit Confurations'

If you do not have a 'App' configuration you will need to create one, else select you 'App' configuration and skip the creating steps. Also if your configuration is corrupt you may need to delete it but first backup your project. To delete a corrupt configuration, select it by expanding the 'Android App' node and chose the '-' button.

To create a new configuration, select the '+' button and select 'Android App'

If you have just created the configuration you will be presented with the following default name value of 'Unnamed' and module will have the value '<no module>' then hit 'Apply' and 'OK'.

Set this the name to 'App' and select 'app' as the module.

Next select 'App' as the run configuration and Run.

Thats it!

I think it is fine because I've seen many people doing this way.

If you are just defining the event handler within the directive, you do not have to define it on the scope, though. Following would be fine.

myApp.directive('clickme', function() {
  return function(scope, element, attrs) {
    var clickingCallback = function() {
      alert('clicked!')
    };
    element.bind('click', clickingCallback);
  }
});

As a much clearer recursive function: http://jsfiddle.net/dmz2x117/

function isPalindrome(letters) {

    var characters  = letters.split(''),
        firstLetter = characters.shift(),
        lastLetter  = characters.pop();

    if (firstLetter !== lastLetter) {
        return false;
    }

    if (characters.length < 2) {
        return true;
    }

    return isPalindrome(characters.join(''));

}

I was just fighting with this exact scenario, but with quite a few more views that needed to resize and move down as necessary. It was driving me nuts, but I finally figured it out.

Here's the key: Interface Builder likes to throw in extra constraints as you add and move views and you may not notice. In my case, I had a view half way down that had an extra constraint that specified the size between it and its superview, basically pinning it to that point. That meant that nothing above it could resize larger because it would go against that constraint.

An easy way to tell if this is the case is by trying to resize the label manually. Does IB let you grow it? If it does, do the labels below move as you expect? Make sure you have both of these checked before you resize to see how your constraints will move your views:

If the view is stuck, follow the views that are below it and make sure one of them doesn't have a top space to superview constraint. Then just make sure your number of lines option for the label is set to 0 and it should take care of the rest.

Constructor typically is Method.

When we create object of a class new operator use then we invoked a special kind of method called constructor.

Constructor used to perform initialization of instance variable.

Code:

public class Diff{

public Diff() { //same as class name so constructor 

        String A = "Local variable A in Constructor:";
        System.out.println(A+ "Contructor Print me");
    }
   public void Print(){
        String B = "Local variable B in Method";
        System.out.println(B+ "Method print me");
    } 


    public static void main(String args[]){
        Diff ob = new Diff();

        }
}

`

• Output:

  Local variable A in Constructor:Contructor Print me

So,only show here Constructor method Diff() statement because we create Diff class object. In that case constructor always come first to instantiate Class here class Diff().

typically,

Constructor is set up feature.

Everything start with here, when we call ob object in the main method constructor takes this class and create copy and it's load into the " Java Virtual Machine Class loader " .

This class loader takes this copy and load into memory,so we can now use it by referencing.

Constructor done its work then Method are come and done its real implementation.

In this program when we call

ob.print();

then method will coming.

Here is my solution to a modal that can be rendered on any screen and initialized in App.tsx

ModalComponent.tsx

import React, { Component } from 'react';
import { Modal, Text, TouchableHighlight, View, StyleSheet, Platform } from 'react-native';
import EventEmitter from 'events';
// I keep localization files for strings and device metrics like height and width which are used for styling 
import strings from '../../config/strings';
import metrics from '../../config/metrics';

const emitter = new EventEmitter();
export const _modalEmitter = emitter

export class ModalView extends Component {
    state: {
        modalVisible: boolean,
        text: string,

        </React.Fragment>
    )
}

and to use it from any component

SomeComponent.tsx

import { _modalEmitter } from './{your_path}/ModalComponent'

// Some functions within your component

showModal(modalText, callbackOnSubmit, callbackOnClose) {
    _modalEmitter.emit(strings.modalOpen, { text: modalText, onSubmit: callbackOnSubmit.bind(this), onClose: callbackOnClose.bind(this) })
}

closeModal() {
    _modalEmitter.emit(strings.modalClose)
}

Hope I was able to help some of you, I used a very similar structure for in-app notifications

Happy coding

For multiple headers do as follow:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('param1', '212212')
req.add_header('param2', '12345678')
req.add_header('other_param1', 'sample')
req.add_header('other_param2', 'sample1111')
req.add_header('and_any_other_parame', 'testttt')
resp = urllib2.urlopen(req)
content = resp.read()

There is no performance difference.

A const_iterator is an iterator that points to const value (like a const T* pointer); dereferencing it returns a reference to a constant value (const T&) and prevents modification of the referenced value: it enforces const-correctness.

When you have a const reference to the container, you can only get a const_iterator.

Edited: I mentionned “The const_iterator returns constant pointers” which is not accurate, thanks to Brandon for pointing it out.

Edit: For COW objects, getting a non-const iterator (or dereferencing it) will probably trigger the copy. (Some obsolete and now disallowed implementations of std::string use COW.)

You could also use Format$(Now(), "Short Date") or whatever date format you want. Be aware, this function will return the Date as a string, so using Date() is a better approach.

Schema is a container of objects. It is owned by a user.

In addition to @Elltz answer, we can use both fill and image for background:

someNode.setBackground(
            new Background(
                    Collections.singletonList(new BackgroundFill(
                            Color.WHITE, 
                            new CornerRadii(500), 
                            new Insets(10))),
                    Collections.singletonList(new BackgroundImage(
                            new Image("image/logo.png", 100, 100, false, true),
                            BackgroundRepeat.NO_REPEAT,
                            BackgroundRepeat.NO_REPEAT,
                            BackgroundPosition.CENTER,
                            BackgroundSize.DEFAULT))));

Use

setBackground(
                new Background(
                        Collections.singletonList(new BackgroundFill(
                                Color.WHITE,
                                new CornerRadii(0),
                                new Insets(0))),
                        Collections.singletonList(new BackgroundImage(
                                new Image("file:clouds.jpg", 100, 100, false, true),
                                BackgroundRepeat.NO_REPEAT,
                                BackgroundRepeat.NO_REPEAT,
                                BackgroundPosition.DEFAULT,
                                new BackgroundSize(1.0, 1.0, true, true, false, false)
                        ))));

(different last argument) to make the image full-window size.

Here is an example of implementing stack in java (Array Based implementation):

public class MyStack extends Throwable{

/**
 * 
 */
private static final long serialVersionUID = -4433344892390700337L;

protected static int top = -1;
protected static int capacity;
protected static int size;

public int stackDatas[] = null;

public MyStack(){
    stackDatas = new int[10];
    capacity = stackDatas.length;
}

public static int size(){

    if(top < 0){
        size = top + 1;
        return size;
    }
    size = top+1;
    return size; 
}

public void push(int data){
    if(capacity == size()){
        System.out.println("no memory");
    }else{
        stackDatas[++top] = data;
    }
}

public boolean topData(){
    if(top < 0){
        return true;
    }else{
        System.out.println(stackDatas[top]);
        return false;
    }
}

public void pop(){
    if(top < 0){
        System.out.println("stack is empty");
    }else{
        int temp = stackDatas[top];
        stackDatas = ArrayUtils.remove(stackDatas, top--);
        System.out.println("poped data---> "+temp);
    }
}

public String toString(){
    String result = "[";

    if(top<0){
        return "[]";
    }else{


    for(int i = 0; i< size(); i++){
        result = result + stackDatas[i] +",";
    }
    }

    return result.substring(0, result.lastIndexOf(",")) +"]";
 }
}

calling MyStack:

    public class CallingMyStack {

public static MyStack ms;

public static void main(String[] args) {

    ms = new MyStack();
    ms.push(1);
    ms.push(2);
    ms.push(3);
    ms.push(4);
    ms.push(5);
    ms.push(6);
    ms.push(7);
    ms.push(8);
    ms.push(9);
    ms.push(10);
    System.out.println("size: "+MyStack.size());
    System.out.println("List---> "+ms);
    System.out.println("----------");
    ms.pop();
    ms.pop();
    ms.pop();
    ms.pop();
    System.out.println("List---> "+ms);
    System.out.println("size: "+MyStack.size());

 }
}

output:

size: 10
List---> [1,2,3,4,5,6,7,8,9,10]
----------
poped data---> 10
poped data---> 9
poped data---> 8
poped data---> 7
List---> [1,2,3,4,5,6]
size: 6

Check the permissions on your Ruby script (may not have execute permission), your theme file and directory (in case it can't read the theme or tries to create other themes in there), and the directory you're in when you run the script (in case it makes temporary files in the current directory rather then /tmp).

Any one of them could be causing you grief.

A nice way to think of it is...

prototype is used by constructor functions. It should've really been called something like, "prototypeToInstall", since that's what it is.

and __proto__ is that "installed prototype" on an object (that was created/installed upon the object from said constructor() function)

Better solution is to introduce another interface for async operations. New interface must inherit from original interface.

Example:

interface IIO
{
    void DoOperation();
}

interface IIOAsync : IIO
{
    Task DoOperationAsync();
}


class ClsAsync : IIOAsync
{
    public void DoOperation()
    {
        DoOperationAsync().GetAwaiter().GetResult();
    }

    public async Task DoOperationAsync()
    {
        //just an async code demo
        await Task.Delay(1000);
    }
}


class Program
{
    static void Main(string[] args)
    {
        IIOAsync asAsync = new ClsAsync();
        IIO asSync = asAsync;

        Console.WriteLine(DateTime.Now.Second);

        asAsync.DoOperation();
        Console.WriteLine("After call to sync func using Async iface: {0}", 
            DateTime.Now.Second);

        asAsync.DoOperationAsync().GetAwaiter().GetResult();
        Console.WriteLine("After call to async func using Async iface: {0}", 
            DateTime.Now.Second);

        asSync.DoOperation();
        Console.WriteLine("After call to sync func using Sync iface: {0}", 
            DateTime.Now.Second);

        Console.ReadKey(true);
    }
}

P.S. Redesign your async operations so they return Task instead of void, unless you really must return void.

You are not returning a response object from your view my_form_post. The function ends with implicit return None, which Flask does not like.

Make the function my_form_post return an explicit response, for example

return 'OK'

at the end of the function.

Delete all PODs in all Namespace only (restart deployment)

 kubectl get pod -A -o yaml | kubectl delete -f -

<section ng-controller="testController as ctrl" class="test_cls"  data-ng-init="fn_load()">

$scope.fn_load = function () {
  console.log("page load")
};

To act on a checkbox being checked or unchecked on click.

$('#customCheck1').click(function() {
  if (this.checked) {
    console.log('checked');
  } else {
    console.log('un-checked');
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" id="customCheck1">

EDIT: Not a nice programming expression if (boolean == true) though .checked property might return other type variables as well..

It is better to use .prop("checked") instead. It returns true and false only.

ssh-keygen -t rsa

When asked for a passphrase ,leave it blank i.e, just press enter. as simple as that!!

Use the next query:

DECLARE 
  EmpIDVar INT;

BEGIN
  EmpIDVar := 1234;

  SELECT *
  FROM Employees
  WHERE EmployeeID = EmpIDVar;
END;

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

I have the same problem with that guy here: mrexcel.com/forum/excel-questions/318115-enablecalculation.html Application.CalculateFull sold my problem. However I am afraid if this will happen again. I will try not to use EnableCalculation again.

Well, looking at the :help columns, it's not really being made to mess with.

In console, it's usually determined by console setting (i.e. it's detected automatically) ; in GUI, it determines (and is determined by) the width of the gvim windows.

So normally you just let consoles and window managers doing their jobs by commented out the set columns

I am not sure what you mean by "see and anticipate line overflow". If you want EOL to be inserted roughly column 80, use either set textwidth or set wrapmargin; if you just want soft wrap (i.e. line is wrapped, but no actual EOL), then play with set linebreak and set showbreak.

Your case is an extreme one, but here is a solution for others that fits a more common scenario of wanting to style fewer than 4 borders exactly the same.

border: 1px dashed red; border-width: 1px 1px 0 1px;

that is a little shorter, and maybe easier to read than

border-top: 1px dashed red;  border-right: 1px dashed red; border-left: 1px dashed red;

or

border-color: red; border-style: dashed; border-width: 1px 1px 0 1px;

This only works in Oracle 10G and greater.

Basically, you use regex_substr to do a split on the string.

That happened to me too, because I was trying to get an IEnumerable but the response had a single value. Please try to make sure it's a list of data in your response. The lines I used (for api url get) to solve the problem are like these:

HttpResponseMessage response = await client.GetAsync("api/yourUrl");

if (response.IsSuccessStatusCode)
{
    IEnumerable<RootObject> rootObjects =
        awaitresponse.Content.ReadAsAsync<IEnumerable<RootObject>>();

    foreach (var rootObject in rootObjects)
    {
        Console.WriteLine(
            "{0}\t${1}\t{2}",
            rootObject.Data1, rootObject.Data2, rootObject.Data3);
    }

    Console.ReadLine();
}

Hope It helps.

One of the possible solutions is:

const names = {
afshin: 'afshin',
saeed: 'saeed',
larry: 'larry'
};

switch (varName) {
   case names[varName]: {
       alert('Hey');
       break;
   }

   default: {
       alert('Default case');
       break;
   }
}

For me a simple windows update fixed it, I wish I tried it before.

Just to add to things from several of the posts above:

read() -- at least on my system -- returns ssize_t. This is like size_t, except is signed. On my system, it's a long, not an int. You might get compiler warnings if you use int, depending on your system, your compiler, and what warnings you have turned on.

You could just make:

<div style="text-align: center; border: 1px solid">_x000D_
  <input type="button" value="button">_x000D_
</div>

Or you could do it like this instead:

<div style="border: 1px solid">_x000D_
  <input type="button" value="button" style="display: block; margin: 0 auto;">_x000D_
</div>

The first one will center align everything inside the div. The other one will center align just the button.

Try this

<TextBlock x:Name="txtblock" FontSize="24" >Hai Welcom to this page
</TextBlock>

Code Behind

var txtblock = sender as Textblock;
txtblock.Foreground = "Red"

You can use the function file_get_contents();

if(file_get_contents('https://example.com/example.txt')) {
    //File exists
}

In this particular case, an even simpler fix would be to just get rid of the "+" all together because AGE is a string literal and what comes before and after are also string literals. You could write line 3 as:

str += "Do you feel " AGE " years old?";

This is because most C/C++ compilers will concatenate string literals automatically. The above is equivalent to:

str += "Do you feel " "42" " years old?";

which the compiler will convert to:

str += "Do you feel 42 years old?";

That is the timeout to create the connection, NOT a timeout for commands executed over that connection.

See for instance http://www.connectionstrings.com/all-sql-server-connection-string-keywords/ (note that the property is "Connect Timeout" (or "Connection Timeout"), not just "Timeout")

From the comments:

It is not possible to set the command timeout through the connection string. However, the SqlCommand has a CommandTimeout property (derived from DbCommand) where you can set a timeout (in seconds) per command.

Do note that when you loop over query results with Read(), the timeout is reset on every read. The timeout is for each network request, not for the total connection.

Once java-8 is out (March 2014) you'll be able to use streams:

If you have a List<Integer>

int sum = list.stream().mapToInt(Integer::intValue).sum();

If it's an int[]

int sum = IntStream.of(a).sum();

FractionallySizedBox may also be useful. You can also read the screen width directly out of MediaQuery.of(context).size and create a sized box based on that

MediaQuery.of(context).size.width * 0.65

if you really want to size as a fraction of the screen regardless of what the layout is.

This code will works:

 your_path= ActiveWorkbook.Path & "\your_python_file.py" 

 Shell "RunDll32.Exe Url.Dll,FileProtocolHandler " & your_path, vbNormalFocus 

ActiveWorkbook.Path return the current directory of the workbook. The shell command open the file through the shell of Windows.

For what you are trying to do, instead of PreparedStatement you can use Statement. Your code may be modified as-

String sql = "SELECT column_name from information_schema.columns where table_name='suppliers';";

Statement s  = connection.createStatement();
ResultSet rs = s.executeQuery(sql);

Hope this helps.

Given a data setup like this:

The formula in cell D2 and copied down is:

=INDEX($B$2:$B$28,MATCH(1,INDEX(($A$2:$A$28=LARGE($A$2:$A$28,ROWS(D$1:D1)))*(COUNTIF(D$1:D1,$B$2:$B$28)=0),),0))

This formula will work even if there are tied OPS scores among players.

You can .write() the content into the iframe document. Example:

<iframe id="FileFrame" src="about:blank"></iframe>

<script type="text/javascript">
   var doc = document.getElementById('FileFrame').contentWindow.document;
   doc.open();
   doc.write('<html><head><title></title></head><body>Hello world.</body></html>');
   doc.close();
</script>

You can use the oncontextmenu event for doing this.

But if the user turns off javascript then you won't be able to handle this.

window.oncontextmenu = function () {
   return false;
}

will disable right click menu.

C is a very low-level language, so it permits you to create almost any legal object (.o) file that you can conceive of. You should think of C as basically dressed-up assembly language.

In particular, C does not require functions to be declared before they are used. If you call a function without declaring it, the use of the function becomes it's (implicit) declaration. In a simple test I just ran, this is only a warning in the case of built-in library functions like printf (at least in GCC), but for random functions, it will compile just fine.

Of course, when you try to link, and it can't find foo, then you will get an error.

In the case of library functions like printf, some compilers contain built-in declarations for them so they can do some basic type checking, so when the implicit declaration (from the use) doesn't match the built-in declaration, you'll get a warning.

This is because, even though Var1 exists, you're also using an assignment statement on the name Var1 inside of the function (Var1 -= 1 at the bottom line). Naturally, this creates a variable inside the function's scope called Var1 (truthfully, a -= or += will only update (reassign) an existing variable, but for reasons unknown (likely consistency in this context), Python treats it as an assignment). The Python interpreter sees this at module load time and decides (correctly so) that the global scope's Var1 should not be used inside the local scope, which leads to a problem when you try to reference the variable before it is locally assigned.

Using global variables, outside of necessity, is usually frowned upon by Python developers, because it leads to confusing and problematic code. However, if you'd like to use them to accomplish what your code is implying, you can simply add:

global Var1, Var2

inside the top of your function. This will tell Python that you don't intend to define a Var1 or Var2 variable inside the function's local scope. The Python interpreter sees this at module load time and decides (correctly so) to look up any references to the aforementioned variables in the global scope.

Some Resources

• the Python website has a great explanation for this common issue.
• Python 3 offers a related nonlocal statement - check that out as well.

I didn't see it mentioned here, but this appears to be case sensitive. Once I changed to /Bin the files were ignored as expected.

"What's your favourite debugger?"
"What's your favourite profiler?"

The actual application/ide/frontend doesn't matter much as long as it goes beyond "notepad, echo and microtime()". It's so unlikely you hire the one in a billion developer that writes perfect code all the time and his/her unit tests spotted all the errors and bottlenecks before they even occur that you want someone who can profile and/or step through the code and find errors in finite time. (That's true for probably all languages/platforms but it seems a bit of an underdeveloped skill-set amongst php developers to me, purely subjective speaking)

How to preventing decompilation of any C# application

Pretty much describes the entire situation.

At some point the code will have to be translated to VM bytecode, and the user can get at it then.

Machine code isn't that much different either. A good interactive disassembler/debugger like IDA Pro makes just about any native application transparent. The debugger is smart enough to use AI to identify common APIs, compiler optimizations, etc. it allows the user to meticuloulsy rebuild higher level constructs from the assembly generated from machine code.

And IDA Pro supports .Net to some extent too.

Honestly, after working on an reverse engineering ( for compatibility ) project for a few years, the main thing I got out of my experience is that I probably shouldn't worry too much about people stealing my code. If anyone wants it, it will never be very hard to get it no matter what scheme I implement.

Turns out that I just have to convert @column name testName to all small letters, since it was initially in camel case.

Although I was not able to use the official answer, the question was able to help me solve my problem by letting me know what to investigate.

Change:

@Column(name="testName")
private String testName;

To:

@Column(name="testname")
private String testName;

This seems more straightforward using data.table as it performs the sort while setting the key.

So, if I were to get the top 3 records in sort (ascending order), then,

require(data.table)
d <- data.table(mtcars, key="cyl")
d[, head(.SD, 3), by=cyl]

does it.

And if you want the descending order

d[, tail(.SD, 3), by=cyl] # Thanks @MatthewDowle

Edit: To sort out ties using mpg column:

d <- data.table(mtcars, key="cyl")
d.out <- d[, .SD[mpg %in% head(sort(unique(mpg)), 3)], by=cyl]

#     cyl  mpg  disp  hp drat    wt  qsec vs am gear carb rank

#  7:   6 17.8 167.6 123 3.92 3.440 18.90  1  0    4    4    2
#  8:   8 14.3 360.0 245 3.21 3.570 15.84  0  0    3    4    7
#  9:   8 10.4 472.0 205 2.93 5.250 17.98  0  0    3    4   14
# 10:   8 10.4 460.0 215 3.00 5.424 17.82  0  0    3    4    5
# 11:   8 13.3 350.0 245 3.73 3.840 15.41  0  0    3    4    3

# and for last N elements, of course it is straightforward
d.out <- d[, .SD[mpg %in% tail(sort(unique(mpg)), 3)], by=cyl]

I didn't see this question initially and asked a similar question a few days later. I am going to take my previous question down, but I thought I'd add an answer here to explain how I used sqldf() to do this.

There's been little bit of discussion as to the best way to import 2GB or more of text data into an R data frame. Yesterday I wrote a blog post about using sqldf() to import the data into SQLite as a staging area, and then sucking it from SQLite into R. This works really well for me. I was able to pull in 2GB (3 columns, 40mm rows) of data in < 5 minutes. By contrast, the read.csv command ran all night and never completed.

Here's my test code:

Set up the test data:

bigdf <- data.frame(dim=sample(letters, replace=T, 4e7), fact1=rnorm(4e7), fact2=rnorm(4e7, 20, 50))
write.csv(bigdf, 'bigdf.csv', quote = F)

I restarted R before running the following import routine:

library(sqldf)
f <- file("bigdf.csv")
system.time(bigdf <- sqldf("select * from f", dbname = tempfile(), file.format = list(header = T, row.names = F)))

I let the following line run all night but it never completed:

system.time(big.df <- read.csv('bigdf.csv'))

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

http://docs.python.org/2/howto/unicode.html

The output of ps aux looks like you did not start docker through systemd/systemctl.

It looks like you started it with:

sudo dockerd -H gridsim1103:2376

When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.

The correct way to start docker is to use systemd/systemctl:

systemctl enable docker
systemctl start docker

After this, docker should start on system start.

EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.

Funny how many broader issues this announcement has dredged up. Dan Lyke had a very entertaining and thoughtful discussion on his website, Flutterby, about developing Interprocess Standards as a way of bootstrapping new languages (and other ramifications, but that's the one that is germane here).

I think this works:

$(document).ready(function(){

    // Hide (collapse) the toggle containers on load
    $(".toggle_container").hide();

    // Switch the "Open" and "Close" state per click then 
    // slide up/down (depending on open/close state)
    $("h2.trigger").click(function(){
        $(this).toggleClass("active").next().slideToggle("slow");
        return false; // Prevent the browser jump to the link anchor
    });
});

Oftentimes you see the suggestion use use keyword arguments, with default values, instead. Look into that.

File-New-File.Make a Swift class named AppExtension.Add the following.

        extension UIViewController{
            func validateEmailAndGetBoolValue(candidate: String) -> Bool {
                let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,6}"
                return NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluateWithObject(candidate)
            }
        }

        Use: 
        var emailValidator:Bool?
        self.emailValidator =  self.validateEmailAndGetBoolValue(resetEmail!)
                        print("emailValidator : "+String(self.emailValidator?.boolValue))

        Use a loop to alternate desired results.


    OR
        extension String
        {
        //Validate Email
            var isEmail: Bool {
                do {
                    let regex = try NSRegularExpression(pattern: "^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$", options: .CaseInsensitive)
                    return regex.firstMatchInString(self, options: NSMatchingOptions(rawValue: 0), range: NSMakeRange(0, self.characters.count)) != nil
                } catch {
                    return false
                }

            }
        }

        Use:
        if(resetEmail!.isEmail)
                        {
                        AppController().requestResetPassword(resetEmail!)
                        self.view.makeToast(message: "Sending OTP")
                        }
                        else
                        {
                            self.view.makeToast(message: "Please enter a valid email")
                        }

Following code is a sample. Question based on the same, instead of using IDE based conversion, is there a faster way to implement so that in future the changes occur, we do not need to modify the values over and over again?

@Override
    public String toString() {
        return "ContractDTO{" +
                "contractId='" + contractId + '\'' +
                ", contractTemplateId='" + contractTemplateId + '\'' +
                '}';
    }

http://rolandtapken.de/blog/2012-04/java-process-httpproxyuser-and-httpproxypassword says:

Other suggest to use a custom default Authenticator. But that's dangerous because this would send your password to anybody who asks.

This is relevant if some http/https requests don't go through the proxy (which is quite possible depending on configuration). In that case, you would send your credentials directly to some http server, not to your proxy.

He suggests the following fix.

// Java ignores http.proxyUser. Here come's the workaround.
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        if (getRequestorType() == RequestorType.PROXY) {
            String prot = getRequestingProtocol().toLowerCase();
            String host = System.getProperty(prot + ".proxyHost", "");
            String port = System.getProperty(prot + ".proxyPort", "80");
            String user = System.getProperty(prot + ".proxyUser", "");
            String password = System.getProperty(prot + ".proxyPassword", "");

            if (getRequestingHost().equalsIgnoreCase(host)) {
                if (Integer.parseInt(port) == getRequestingPort()) {
                    // Seems to be OK.
                    return new PasswordAuthentication(user, password.toCharArray());  
                }
            }
        }
        return null;
    }  
});

I haven't tried it yet, but it looks good to me.

I modified the original version slightly to use equalsIgnoreCase() instead of equals(host.toLowerCase()) because of this: http://mattryall.net/blog/2009/02/the-infamous-turkish-locale-bug and I added "80" as the default value for port to avoid NumberFormatException in Integer.parseInt(port).

Short answer, you can't.

HTML is used for the page's structure and can't send e-mails, you will need a server side language (such as PHP) to send e-mails, you can also use a third party service and let them handle the e-mail sending for you.

You can read it, but you can't set it. value="123" will be ignored, so it won't have a value until you click on it and pick a file.

Even then, the value will likely be mangled with something like c:\fakepath\ to keep the details of the user's filesystem private.

Another alternative approach is:

How do I create a Java string from the contents of a file?

Other option is to use utilities provided open source libraries
http://commons.apache.org/io/api-1.4/index.html?org/apache/commons/io/IOUtils.html

Why java doesn't provide such a common util API ?
a) to keep the APIs generic so that encoding, buffering etc is handled by the programmer.
b) make programmers do some work and write/share opensource util libraries :D ;-)

        ]
    ]);

MP3 files have headers you need to respect.

You could ether use a library like Open Source Audio Library Project and write a tool around it. Or you can use a tool that understands mp3 files like Audacity.

you can simply use rstrip:

    for stuff in largestring:
        print(stuff.rstrip("\n")

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Documentation: http://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/uppercaseString

You can also use lowercaseString and capitalizedString

Just as a reference, here is an example of how to convert between String and char[] with a dynamic length -

// Define 
String str = "This is my string"; 

// Length (with one extra character for the null terminator)
int str_len = str.length() + 1; 

// Prepare the character array (the buffer) 
char char_array[str_len];

// Copy it over 
str.toCharArray(char_array, str_len);

Yes, this is painfully obtuse for something as simple as a type conversion, but sadly it's the easiest way.

Search for the "datalist" tag.

<input list="texto_pronto" name="input_normal">
<datalist id="texto_pronto">
    <option value="texto A">
    <option value="texto B">
</datalist>

The easiest way seems to be subtracting the second number from the first:

var numericArray:Array<number> = [2,3,4,1,5,8,11];

var sorrtedArray:Array<number> = numericArray.sort((n1,n2) => n1 - n2);

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

No! You should avoid using HTML entities.

Instead of using HTML entities for symbols you should just put those symbols directly into your text and correctly encode your document.

• Instead of using £ you should use the character £.
• For rupee there is no Unicode character. You can use a PNG file instead . Alternatively you can use the unicode character ?? which is currently the most commonly used single character for rupee. Other alternatives are using INR, Rs. or rupees.

When the new Unicode symbol for the Indian Rupee is introduced then could use that instead (but note that it will be a while before all browsers support it).

I learned something really useful and fundamental from here.

chaining functions is very usefull in this case which works on most jQuery Functions including on function output too.

It works because output of most jQuery functions are the input objects sets so you can use them right away and make it shorter and smarter

function showPhotos() {
    $(this).find("span").slideToggle();
}

$(".photos")
    .on("mouseenter", "li", showPhotos)
    .on("mouseleave", "li", showPhotos);

... I don't know if you're using an activex button or not, but when I insert an activex button into sheet1 in Excel called CommandButton1, the following code works fine:

Sub test()

   Sheets(1).CommandButton1.Enabled = False

End Sub

Hope this helps...

For example you have Animal superclass and Cat subclass.Say your subclass has speak(); method.

class Animal{

  public void walk(){

  }

}

class Cat extends Animal{

  @Override
  public void walk(){

  }

  public void speak(){

  }

  public void main(String args[]){

    Animal a=new Cat();
    //a.speak(); Compile Error
    // If you use speak method for "a" reference variable you should downcast. Like this:

    ((Cat)a).speak();
  }

}

for Python 3.7.4 following set of commands worked: Before those command, you need to confirm Desktop with C++ and Python is installed in Visual Studio.

cd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build"
vcvarsall.bat x86_amd64
cd \
set CL=-FI"%VCINSTALLDIR%\tools\msvc\14.16.27023\include\stdint.h"


pip install pycrypto

Another way (credit):

@For /F "tokens=2,3,4 delims=/ " %%A in ('Date /t') do @( 
    Set Month=%%A
    Set Day=%%B
    Set Year=%%C
)

@echo DAY = %Day%
@echo Month = %Month%
@echo Year = %Year%

Note that both my answers here are still reliant on the order of the day and month as determined by regional settings - not sure how to work around that.

All I did to achieve a reverse string is use the xrange function with the length of the string in a for loop and step back per the following:

myString = "ABC"

for index in xrange(len(myString),-1):
    print index

My output is "CBA"

Okay, so you've got two options here :

1. Use jQuery UI's accordion - its nice, easy and fast. See more info here
2. Or, if you still wanna do this by yourself, you could remove the fieldset (its not semantically right to use it for this anyway) and create a structure by yourself.

Here's how you do that. Create a HTML structure like this :

<div class="container">
    <div class="header"><span>Expand</span>

    </div>
    <div class="content">
        <ul>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
            <li>This is just some random content.</li>
        </ul>
    </div>
</div>

With this CSS: (This is to hide the .content stuff when the page loads.

.container .content {
    display: none;
    padding : 5px;
}

Then, using jQuery, write a click event for the header.

$(".header").click(function () {

    $header = $(this);
    //getting the next element
    $content = $header.next();
    //open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
    $content.slideToggle(500, function () {
        //execute this after slideToggle is done
        //change text of header based on visibility of content div
        $header.text(function () {
            //change text based on condition
            return $content.is(":visible") ? "Collapse" : "Expand";
        });
    });

});

Here's a demo : http://jsfiddle.net/hungerpain/eK8X5/7/

No need to touch hot_standby_feedback. As others have mentioned, setting it to on can bloat master. Imagine opening transaction on a slave and not closing it.

Instead, set max_standby_archive_delay and max_standby_streaming_delay to some sane value:

# /etc/postgresql/10/main/postgresql.conf on a slave
max_standby_archive_delay = 900s
max_standby_streaming_delay = 900s

This way queries on slaves with a duration less than 900 seconds won't be cancelled. If your workload requires longer queries, just set these options to a higher value.

Here is best solution for this issue: In View add all the ID (Keys). Consider having multiple tables named (First, Second and Third)

@Html.HiddenFor(model=>model.FirstID)
@Html.HiddenFor(model=>model.SecondID)
@Html.HiddenFor(model=>model.Second.SecondID)
@Html.HiddenFor(model=>model.Second.ThirdID)
@Html.HiddenFor(model=>model.Second.Third.ThirdID)

In C# code,

[HttpPost]
public ActionResult Edit(First first)
{
  if (ModelState.Isvalid)
  {
    if (first.FirstID > 0)
    {
      datacontext.Entry(first).State = EntityState.Modified;
      datacontext.Entry(first.Second).State = EntityState.Modified;
      datacontext.Entry(first.Second.Third).State = EntityState.Modified;
    }
    else
    {
      datacontext.First.Add(first);
    }
    datacontext.SaveChanges();
    Return RedirectToAction("Index");
  }

 return View(first);
}

aws s3 ls s3://bucket-name/folder-prefix-if-any --recursive | wc -l

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar

You can always run this:

java -cp HelloWorld.jar HelloWorld

-cp HelloWorld.jar adds the jar to the classpath, then HelloWorld runs the class you wrote.

To create a runnable jar with a main class with no package, add Class-Path: . to the manifest:

Manifest-Version: 1.0
Class-Path: .
Main-Class: HelloWorld

I would advise using a package to give your class its own namespace. E.g.

package com.stackoverflow.user.blrp;

public class HelloWorld {
    ...
}

Just had the same problem. Client-side wasn't appropriate because the button was posting back information from a listview.

Saw same solution as Amaranth's on way2coding but this didn't work for me.

However, in the comments, someone posted a similar solution that does work

OnClientClick="document.getElementById('form1').target ='_blank';"

where form1 is the id of your asp.net form.

here is code:

<?php echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>'; ?>

The Android Developer Guide has a section called Building Custom Components. Unfortunately, the discussion of XML attributes only covers declaring the control inside the layout file and not actually handling the values inside the class initialisation. The steps are as follows:

1. Declare attributes in values\attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="MyCustomView">
        <attr name="android:text"/>
        <attr name="android:textColor"/>            
        <attr name="extraInformation" format="string" />
    </declare-styleable>
</resources>

Notice the use of an unqualified name in the declare-styleable tag. Non-standard android attributes like extraInformation need to have their type declared. Tags declared in the superclass will be available in subclasses without having to be redeclared.

2. Create constructors

Since there are two constructors that use an AttributeSet for initialisation, it is convenient to create a separate initialisation method for the constructors to call.

private void init(AttributeSet attrs) { 
    TypedArray a=getContext().obtainStyledAttributes(
         attrs,
         R.styleable.MyCustomView);

    //Use a
    Log.i("test",a.getString(
         R.styleable.MyCustomView_android_text));
    Log.i("test",""+a.getColor(
         R.styleable.MyCustomView_android_textColor, Color.BLACK));
    Log.i("test",a.getString(
         R.styleable.MyCustomView_extraInformation));

    //Don't forget this
    a.recycle();
}

R.styleable.MyCustomView is an autogenerated int[] resource where each element is the ID of an attribute. Attributes are generated for each property in the XML by appending the attribute name to the element name. For example, R.styleable.MyCustomView_android_text contains the android_text attribute for MyCustomView. Attributes can then be retrieved from the TypedArray using various get functions. If the attribute is not defined in the defined in the XML, then null is returned. Except, of course, if the return type is a primitive, in which case the second argument is returned.

If you don't want to retrieve all of the attributes, it is possible to create this array manually.The ID for standard android attributes are included in android.R.attr, while attributes for this project are in R.attr.

int attrsWanted[]=new int[]{android.R.attr.text, R.attr.textColor};

Please note that you should not use anything in android.R.styleable, as per this thread it may change in the future. It is still in the documentation as being to view all these constants in the one place is useful.

3. Use it in a layout files such as layout\main.xml

Include the namespace declaration xmlns:app="http://schemas.android.com/apk/res-auto" in the top level xml element. Namespaces provide a method to avoid the conflicts that sometimes occur when different schemas use the same element names (see this article for more info). The URL is simply a manner of uniquely identifying schemas - nothing actually needs to be hosted at that URL. If this doesn't appear to be doing anything, it is because you don't actually need to add the namespace prefix unless you need to resolve a conflict.

<com.mycompany.projectname.MyCustomView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:text="Test text"
    android:textColor="#FFFFFF"
    app:extraInformation="My extra information"
/> 

Reference the custom view using the fully qualified name.

Android LabelView Sample

If you want a complete example, look at the android label view sample.

LabelView.java

 TypedArray a=context.obtainStyledAttributes(attrs, R.styleable.LabelView);
 CharSequences=a.getString(R.styleable.LabelView_text);

attrs.xml

<declare-styleable name="LabelView">
    <attr name="text"format="string"/>
    <attr name="textColor"format="color"/>
    <attr name="textSize"format="dimension"/>
</declare-styleable>

custom_view_1.xml

<com.example.android.apis.view.LabelView
    android:background="@drawable/blue"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    app:text="Blue" app:textSize="20dp"/>

This is contained in a LinearLayout with a namespace attribute: xmlns:app="http://schemas.android.com/apk/res-auto"

• StackOverflow Thread: Retrieving an XML attribute for custom control
• How do I use obtainStyledAttributes with internal themes of Android
• Defining custom attributes + list of supported attribute formats

A concept can be better delivered with examples, always. I had trouble in comprehending these concept until I dig into Android framework source code, and do some experiments, even after reading all documents in Android developer sites & related stackoverflow threads. I'm gonna share two examples that helped me a lot to fully understand these concepts.

A DatePickerDialog will look different based on level that you put in AndroidManifest.xml file's targetSDKversion(<uses-sdk android:targetSdkVersion="INTEGER_VALUE"/>). If you set the value 10 or lower, your DatePickerDialog will look like left. On the other hand, if you set the value 11 or higher, a DatePickerDialog will look like right, with the very same code.

The code that I used to create this sample is super-simple. MainActivity.java looks :

public class MainActivity extends Activity {

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

    public void onClickButton(View v) {
        DatePickerDialog d = new DatePickerDialog(this, null, 2014, 5, 4);
        d.show();       
    }
}

And activity_main.xml looks :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="onClickButton"
    android:text="Button" />
</RelativeLayout>

That's it. That's really every code that I need to test this.

And this change in look is crystal clear when you see the Android framework source code. It goes like :

public DatePickerDialog(Context context,
    OnDateSetListener callBack,
    int year,
    int monthOfYear,
    int dayOfMonth,
    boolean yearOptional) {
        this(context, context.getApplicationInfo().targetSdkVersion >= Build.VERSION_CODES.HONEYCOMB
                ? com.android.internal.R.style.Theme_Holo_Light_Dialog_Alert
                : com.android.internal.R.style.Theme_Dialog_Alert,
        callBack, year, monthOfYear, dayOfMonth, yearOptional);
}

As you can see, the framework gets current targetSDKversion and set different theme. This kind of code snippet(getApplicationInfo().targetSdkVersion >= SOME_VERSION) can be found here and there in Android framework.

Another example is about WebView class. Webview class's public methods should be called on main thread, and if not, runtime system throws a RuntimeException, when you set targetSDKversion 18 or higher. This behavior can be clearly delivered with its source code. It's just written like that.

sEnforceThreadChecking = context.getApplicationInfo().targetSdkVersion >=
            Build.VERSION_CODES.JELLY_BEAN_MR2;

if (sEnforceThreadChecking) {
    throw new RuntimeException(throwable);
}

The Android doc says, "As Android evolves with each new version, some behaviors and even appearances might change." So, we've looked behavior and appearance change, and how that change is accomplished.

In summary, the Android doc says "This attribute(targetSdkVersion) informs the system that you have tested against the target version and the system should not enable any compatibility behaviors to maintain your app's forward-compatibility with the target version.". This is really clear with WebView case. It was OK until JELLY_BEAN_MR2 released to call WebView class's public method on not-main thread. It is nonsense if Android framework throws a RuntimeException on JELLY_BEAN_MR2 devices. It just should not enable newly introduced behaviors for its interest, which cause fatal result. So, what we have to do is to check whether everything is OK on certain targetSDKversions. We get benefit like appearance enhancement with setting higher targetSDKversion, but it comes with responsibility.

EDIT : disclaimer. The DatePickerDialog constructor that set different themes based on current targetSDKversion(that I showed above) actually has been changed in later commit. Nevertheless I used that example, because logic has not been changed, and those code snippet clearly shows targetSDKversion concept.

In Mgmt Studio, when you are editing the top 200, you can view the SQL pane - either by right clicking in the grid and choosing Pane->SQL or by the button in the upper left. This will allow you to write a custom query to drill down to the row(s) you want to edit.

But ultimately mgmt studio isn't a data entry/update tool which is why this is a little cumbersome.

If you want your numbers in ascending order you can add them into a set and then sort the set into an ascending list.

s = set()
if number1 not in s:
  s.add(number1)
if number2 not in s:
  s.add(number2)
...
s = sorted(s)  #Now a list in ascending order

You can also try this:

db.emails.find($and:[{sent_at:{$exists:true},'sent_at':null}]).count()

With 100k of Javascript, you should never put it inside the file. Use an external script Javascript file. There's no chance in hell you'll only ever use this amount of code in only one HTML page. Likely you're asking where you should load the Javascript file, for this you've received satisfactory answers already.

But I'd like to point out that commonly, modern browsers accept gzipped Javascript files! Just gzip the x.js file to x.js.gz, and point to that in the src attribute. It doesn't work on the local filesystem, you need a webserver for it to work. But the savings in transferred bytes can be enormous.

I've successfully tested it in Firefox 3, MSIE 7, Opera 9, and Google Chrome. It apparently doesn't work this way in Safari 3.

For more info, see this blog post, and another very ancient page that nevertheless is useful because it points out that the webserver can detect whether a browser can accept gzipped Javascript, or not. If your server side can dynamically choose to send the gzipped or the plain text, you can make the page usable in all web browsers.

The idea of mapping an function to array of data comes from functional programming. You shouldn't think about array_map as a foreach loop that calls a function on each element of the array (even though that's how it's implemented). It should be thought of as applying the function to each element in the array independently.

In theory such things as function mapping can be done in parallel since the function being applied to the data should ONLY affect the data and NOT the global state. This is because an array_map could choose any order in which to apply the function to the items in (even though in PHP it doesn't).

array_walk on the other hand it the exact opposite approach to handling arrays of data. Instead of handling each item separately, it uses a state (&$userdata) and can edit the item in place (much like a foreach loop). Since each time an item has the $funcname applied to it, it could change the global state of the program and therefor requires a single correct way of processing the items.

Back in PHP land, array_map and array_walk are almost identical except array_walk gives you more control over the iteration of data and is normally used to "change" the data in-place vs returning a new "changed" array.

array_filter is really an application of array_walk (or array_reduce) and it more-or-less just provided for convenience.

It sounds like you might need to create and query linked database servers in SQL Server

At the moment you've created a query that's going between different databases using a 3 part name mydatabase.dbo.mytable but you need to go up a level and use a 4 part name myserver.mydatabase.dbo.mytable, see this post on four part naming for more info

edit
The four part naming for your existing query would be as shown below (which I suspect you may have already tried?), but this assumes you can "get to" the remote database with the four part name, you might need to edit your host file / register the server or otherwise identify where to find database.windows.net.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks])
SELECT [InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks] FROM [BC1-PC].[testdabse].[dbo].[invoice]

If you can't access the remote server then see if you can create a linked database server:

EXEC sp_addlinkedserver [database.windows.net];
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [database.windows.net].basecampdev.dbo.invoice;
GO

Then you can just query against MyEmployee without needing the full four part name

If it's a local development tomcat launched from IDE, then restarting this IDE and rebuild project also helps.

Update:

You could also try to find if there is any running tomcat process in the background and kill it.

If you want to write it to disk so that it will be easy to read back in as a numpy array, look into numpy.save. Pickling it will work fine, as well, but it's less efficient for large arrays (which yours isn't, so either is perfectly fine).

If you want it to be human readable, look into numpy.savetxt.

Edit: So, it seems like savetxt isn't quite as great an option for arrays with >2 dimensions... But just to draw everything out to it's full conclusion:

I just realized that numpy.savetxt chokes on ndarrays with more than 2 dimensions... This is probably by design, as there's no inherently defined way to indicate additional dimensions in a text file.

E.g. This (a 2D array) works fine

import numpy as np
x = np.arange(20).reshape((4,5))
np.savetxt('test.txt', x)

While the same thing would fail (with a rather uninformative error: TypeError: float argument required, not numpy.ndarray) for a 3D array:

import numpy as np
x = np.arange(200).reshape((4,5,10))
np.savetxt('test.txt', x)

One workaround is just to break the 3D (or greater) array into 2D slices. E.g.

x = np.arange(200).reshape((4,5,10))
with open('test.txt', 'w') as outfile:
    for slice_2d in x:
        np.savetxt(outfile, slice_2d)

However, our goal is to be clearly human readable, while still being easily read back in with numpy.loadtxt. Therefore, we can be a bit more verbose, and differentiate the slices using commented out lines. By default, numpy.loadtxt will ignore any lines that start with # (or whichever character is specified by the comments kwarg). (This looks more verbose than it actually is...)

import numpy as np

# Generate some test data
data = np.arange(200).reshape((4,5,10))

# Write the array to disk
with open('test.txt', 'w') as outfile:
    # I'm writing a header here just for the sake of readability
    # Any line starting with "#" will be ignored by numpy.loadtxt
    outfile.write('# Array shape: {0}\n'.format(data.shape))
    
    # Iterating through a ndimensional array produces slices along
    # the last axis. This is equivalent to data[i,:,:] in this case
    for data_slice in data:

        # The formatting string indicates that I'm writing out
        # the values in left-justified columns 7 characters in width
        # with 2 decimal places.  
        np.savetxt(outfile, data_slice, fmt='%-7.2f')

        # Writing out a break to indicate different slices...
        outfile.write('# New slice\n')

This yields:

# Array shape: (4, 5, 10)
0.00    1.00    2.00    3.00    4.00    5.00    6.00    7.00    8.00    9.00

Reading it back in is very easy, as long as we know the shape of the original array. We can just do numpy.loadtxt('test.txt').reshape((4,5,10)). As an example (You can do this in one line, I'm just being verbose to clarify things):

# Read the array from disk
new_data = np.loadtxt('test.txt')

# Note that this returned a 2D array!
print new_data.shape

# However, going back to 3D is easy if we know the 
# original shape of the array
new_data = new_data.reshape((4,5,10))
    
# Just to check that they're the same...
assert np.all(new_data == data)

**You should be in the newly created YOUR_APP folder before you hit the ng serve command **

Lets start from fresh,

1) install npm

2) create a new angular app ( ng new <YOUR_APP_NAME> )

3) go to app folder (cd YOUR_APP_NAME)

4) ng serve

I hope it will resolve the issue.

In current versions of Mac Catalina

1. go to packages tab --> Settings View ---> Install Packages/Themes ---> +Install button --> add "platformio-ide-terminal"

2. control ~ to get the terminal

With Hibernate you can create your own UserType. So thats what I did for this issue. Something as simple as this:

    public class BytesType implements org.hibernate.usertype.UserType {

         private final int[] SQL_TYPES = new int[] { java.sql.Types.VARBINARY };
     //...
    }

There of course is more to implement from extending your own UserType but I just wanted to throw that out there for anyone looking for other methods.

I believe this "callback" jargon has been mistakenly used in a lot of places. My definition would be something like:

A callback function is a function that you pass to someone and let them call it at some point of time.

I think people just read the first sentence of the wiki definition:

a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code.

I've been working with lots of APIs, see various of bad examples. Many people tend to name a function pointer (a reference to executable code) or anonymous functions(a piece of executable code) "callback", if they are just functions why do you need another name for this?

Actually only the second sentence in wiki definition reveals the differences between a callback function and a normal function:

This allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.

so the difference is who you are going to pass the function and how your passed in function is going to be called. If you just define a function and pass it to another function and called it directly in that function body, don't call it a callback. The definition says your passed in function is gonna be called by "lower-level" function.

I hope people can stop using this word in ambiguous context, it can't help people to understand better only worse.

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

If you know the size of the vector you can do it like this:

#include <bits/stdc++.h>
using namespace std;

int main() {
    int n;
    cin >> n;
    vector<int> v(n);
    for (auto &it : v) {
        cin >> it;
    }
}

According to the API, the headers can all be passed in using requests.get:

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

You can use GitHub API to get the sloc like the following function

function getSloc(repo, tries) {

    //repo is the repo's path
    if (!repo) {
        return Promise.reject(new Error("No repo provided"));
    }

    //GitHub's API may return an empty object the first time it is accessed
    //We can try several times then stop
    if (tries === 0) {
        return Promise.reject(new Error("Too many tries"));
    }

    let url = "https://api.github.com/repos" + repo + "/stats/code_frequency";

    return fetch(url)
        .then(x => x.json())
        .then(x => x.reduce((total, changes) => total + changes[1] + changes[2], 0))
        .catch(err => getSloc(repo, tries - 1));
}

Personally I made an chrome extension which shows the number of SLOC on both github project list and project detail page. You can also set your personal access token to access private repositories and bypass the api rate limit.

You can download from here https://chrome.google.com/webstore/detail/github-sloc/fkjjjamhihnjmihibcmdnianbcbccpnn

You can use the following:

Double bang !! property lookup

var a = !![]; // true
var a = !!null; // false

hasOwnProperty This is something that I used to use:

var myObject = {
  name: 'John',
  address: null
};
if (myObject.hasOwnProperty('address')) { // true
  // do something if it exists.
}

However, JavaScript decided not to protect the method’s name, so it could be tampered with.

var myObject = {
  hasOwnProperty: 'I will populate it myself!'
};

prop in myObject

var myObject = {
  name: 'John',
  address: null,
  developer: false
};
'developer' in myObject; // true, remember it's looking for exists, not value.

typeof

if (typeof myObject.name !== 'undefined') {
  // do something
}

However, it doesn't check for null.

I think this is the best way.

in operator

var myObject = {
  name: 'John',
  address: null
};

if('name' in myObject) {
  console.log("Name exists in myObject");
}else{
  console.log("Name does not exist in myObject");
}

result:

Name exists in myObject

Here is a link that goes into more detail on the in operator: Determining if an object property exists

Here is a more generic solution based on @rindeal solution which does not work on MacOS/BSD (/r expects a file):

cat << DOC > input.txt
abc
cdef
line
DOC

$ cat << EOF | sed '/^cdef$/ r /dev/stdin' input.txt
line 1
line 2
EOF

# outputs:
abc
cdef
line 1
line 2
line

This can be used to pipe anything into the file at the given position:

$ date | sed '/^cdef$/ r /dev/stdin' input.txt

# outputs
abc
cdef
Tue Mar 17 10:50:15 CET 2020
line

Also, you could add multiple commands which allows deleting the marker line cdef:

$ date | sed '/^cdef$/ {
  r /dev/stdin
  d
}' input.txt

# outputs
abc
Tue Mar 17 10:53:53 CET 2020
line

I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

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

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

I hope this answer can be helpful for someone with the same problem.

I think that better solution is configuration of .htaccess In that way you dont have to alter code of application. Here are directives for Apache2

php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

<a href="javascript:window.open('document.aspx','mypopuptitle','width=600,height=400')">open popup</a>

Since I have encoding ISO-8859-1 operating system the date format "dd.MM.yyyy HH:mm:sss" was not recognised what did work was to use InvariantCulture string.

string url = "GetData?DagsPr=" + DagsProfs.ToString(CultureInfo.InvariantCulture)

Joshc's answer was on the right track, but I found that it totally deletes the ?rel=0 querystring and replaces it with the ?wmode=transparent item - which has the effect of displaying the YouTube Suggested Videos list at the end of the playback, even though you originally didn't want this to happen.

I changed the code so that the src attribute of the embedded video is scanned first, to see if there is a question mark ? in it already (because this denotes the presence of a pre-existing query string, which might be something like ?rel=0 but could in theory be anything that YouTube choose to append in the future). If there's a query string already there, we want to preserve it, not destroy it, because it represents a setting chosen by whoever pasted in this YouTube video, and they presumably chose it for a reason!

So, if ? is found, the wmode=transparent will be appended using the format: &mode=transparent to just tag it on the end of the pre-existing query string.

If no ? is found, then the code will work in exactly the same way as it did originally (in toomanyairmiles's post), appending just ?wmode=transparent as a new query string to the URL.

Now, regardless of what may or may not be on the end of the YouTube URL as a query string already, it gets preserved, and the required wmode parameters get injected or added without damage to what was there before.

Here's the code to drop into your document.ready function:

$('iframe').each(function() {
  var url = $(this).attr("src");
  if (url.indexOf("?") > 0) {
    $(this).attr({
      "src" : url + "&wmode=transparent",
      "wmode" : "opaque"
    });
  }
  else {
    $(this).attr({
      "src" : url + "?wmode=transparent",
      "wmode" : "opaque"
    });
  }
});

x(end+1) = newElem is a bit more robust.

x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem, however, works for both row- and column-vectors.

In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)

Works on almost all browsers.

You can try giving padding-bottom as a percentage.

<div style="height:0;width:20%;padding-bottom:20%;background-color:red">
<div>
Content goes here
</div>
</div>

The outer div is making a square and inner div contains the content. This solution worked for me many times.

Here's a jsfiddle

public static int [] locations={1,2,3};

public static test dot=new test();

Declare the above variables above the main method and the code compiles fine.

public static void main(String[] args){

This one worked for me. For only ERROR messages to be displayed as stdout, log4j.properties file may look like:

# Root logger option
log4j.rootLogger=ERROR, stdout
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

NOTE: Put log4j.properties file in src/main/resources folder to be effective. And if log4j.properties doesn't exist (meaning spark is using log4j-defaults.properties file) then you can create it by going to SPARK_HOME/conf and then mv log4j.properties.template log4j.properties and then proceed with above said changes.

Use $elemMatch to find the array of particular object

db.users.findOne({"_id": id},{awards: {$elemMatch: {award:'Turing Award', year:1977}}})

You can't refer to a property of an object before you have initialized that object; use an external variable.

var key1 = "it";
var obj = {
  key1 : key1,
  key2 : key1 + " works!"
};

Also, this is not a "JSON object"; it is a Javascript object. JSON is a method of representing an object with a string (which happens to be valid Javascript code).

Version 1.3.0 has flaw IMO.
Downgrade to version 1.2.3 fixes my problem.

I'm on

• Laravel 5.1
• PHP 5.6.40

Before installation use the Control Panel Region and Language Preferences tool to change everything (Format, Keyboard default input, language for non Unicode programs) to English. Revert to the original selections after the installation.

So far the most elegant and most efficient way to do that in Java:

double newNum = Math.floor(num * 100 + 0.5) / 100;

There are two ways you can do this; with patch and with patch.object

Patch assumes that you are not directly importing the object but that it is being used by the object you are testing as in the following

#foo.py
def some_fn():
    return 'some_fn'

class Foo(object):
    def method_1(self):
        return some_fn()

#bar.py
import foo
class Bar(object):
    def method_2(self):
        tmp = foo.Foo()
        return tmp.method_1()

#test_case_1.py
import bar
from mock import patch

@patch('foo.some_fn')
def test_bar(mock_some_fn):
    mock_some_fn.return_value = 'test-val-1'
    tmp = bar.Bar()
    assert tmp.method_2() == 'test-val-1'
    mock_some_fn.return_value = 'test-val-2'
    assert tmp.method_2() == 'test-val-2'

If you are directly importing the module to be tested, you can use patch.object as follows:

#test_case_2.py
import foo
from mock import patch

@patch.object(foo, 'some_fn')
def test_foo(test_some_fn):
    test_some_fn.return_value = 'test-val-1'
    tmp = foo.Foo()
    assert tmp.method_1() == 'test-val-1'
    test_some_fn.return_value = 'test-val-2'
    assert tmp.method_1() == 'test-val-2'

In both cases some_fn will be 'un-mocked' after the test function is complete.

Edit: In order to mock multiple functions, just add more decorators to the function and add arguments to take in the extra parameters

@patch.object(foo, 'some_fn')
@patch.object(foo, 'other_fn')
def test_foo(test_other_fn, test_some_fn):
    ...

Note that the closer the decorator is to the function definition, the earlier it is in the parameter list.

If you don't mind using numpy, you can use numpy.random.choice.

For example:

import numpy

items  = [["item1", 0.2], ["item2", 0.3], ["item3", 0.45], ["item4", 0.05]
elems = [i[0] for i in items]
probs = [i[1] for i in items]

trials = 1000
results = [0] * len(items)
for i in range(trials):
    res = numpy.random.choice(items, p=probs)  #This is where the item is selected!
    results[items.index(res)] += 1
results = [r / float(trials) for r in results]
print "item\texpected\tactual"
for i in range(len(probs)):
    print "%s\t%0.4f\t%0.4f" % (items[i], probs[i], results[i])

If you know how many selections you need to make in advance, you can do it without a loop like this:

numpy.random.choice(items, trials, p=probs)

$('#datepicker-dep').datepicker({
    minDate: 0
});

minDate:0 works for me.

You may want to declare the button content outside of the dialog, this works for me.

var closeFunction = function() {
    $(#dialog).dialog( "close" );
};

$('#dialog').dialog({
    modal: true,
    buttons: {
        Ok: closeFunction
    }
});

Go to Settings -> Style Configurator

Select Theme: Choose whichever you like best (the top two are easiest to read by most people's preference)

With word-break, a very long word starts at the point it should start and it is being broken as long as required

[X] I am a text that 0123

90123456789 want to live 
inside this narrow paragr
aph.

However, with word-wrap, a very long word WILL NOT start at the point it should start. it wrap to next line and then being broken as long as required

[X] I am a text that 
012345678901234567890123
4567890123456789 want to

I have found that this works:

$(document).ready(function(){
    $('textarea').bind('input propertychange', function() {
        //do your update here
    }

})

It means, when an error happens on the line, it is telling vbscript to continue execution without aborting the script. Sometimes, the On Error follows the Goto label to alter the flow of execution, something like this in a Sub code block, now you know why and how the usage of GOTO can result in spaghetti code:

Sub MySubRoutine()
   On Error Goto ErrorHandler

   REM VB code...

   REM More VB Code...

Exit_MySubRoutine:

   REM Disable the Error Handler!

   On Error Goto 0

   REM Leave....
   Exit Sub

ErrorHandler:

   REM Do something about the Error

   Goto Exit_MySubRoutine
End Sub

change only .htaccess:

Like the other answers said, sp_reset_connection indicates that connection pool is being reused. Be aware of one particular consequence!

Jimmy Mays' MSDN Blog said:

sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.

UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.

ref: SQL Server: Isolation level leaks across pooled connections

Here is some additional information:

What does sp_reset_connection do?

Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.

sp_reset_connection resets the following aspects of a connection:

• All error states and numbers (like @@error)

• Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query

• Waits for any outstanding I/O operations that is outstanding

• Frees any held buffers on the server by the connection

• Unlocks any buffer resources that are used by the connection

• Releases all allocated memory owned by the connection

• Clears any work or temporary tables that are created by the connection

• Kills all global cursors owned by the connection

• Closes any open SQL-XML handles that are open

• Deletes any open SQL-XML related work tables

• Closes all system tables

• Closes all user tables

• Drops all temporary objects

• Aborts open transactions

• Defects from a distributed transaction when enlisted

• Decrements the reference count for users in current database which releases shared database locks

• Frees acquired locks

• Releases any acquired handles

• Resets all SET options to the default values

• Resets the @@rowcount value

• Resets the @@identity value

• Resets any session level trace options using dbcc traceon()

• Resets CONTEXT_INFO to NULL in SQL Server 2005 and newer _{[ not part of the original article ]}

sp_reset_connection will NOT reset:

• Security context, which is why connection pooling matches connections based on the exact connection string

• Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when sp_setapprole is executed.

Note: I am including the list here as I do not want it to be lost in the ever transient web.

You can add this to your ~/.gitconfig file:

[alias]
    add-untracked = !"git status --porcelain | awk '/\\?\\?/{ print $2 }' | xargs git add"

Then, from the commandline, just run:

git add-untracked

I couldn't use the other solutions... What worked for me was installing LocalTunnel.net (https://github.com/danielrmz/localtunnel-net-client), and then using the resulting url on Facebook.

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

I was having the same problem, none of the posted solutions helped. Finally, I figured out what I was doing wrong. When I installed the Java JDK it asked me for a directiy where I wanted to install. I changed the directory to where I wanted the code to go. It then asked for a directory where it could install the Runtime Environment and I selected the SAME DIRECTORY where I installed the JDK. It over wrote my lib folder and erased the tools.jar. Be sure to use different folders during the install. I used my custom folder for the JDK and the default folder for the RE and everything worked fine.

There are a few different ways of doing this. I prefer using apply, since it's easily extendable:

##Generate some data
dd = data.frame(a = 1:4, b= 1:0, c=0:3)

##Go through each row and determine if a value is zero
row_sub = apply(dd, 1, function(row) all(row !=0 ))
##Subset as usual
dd[row_sub,]

Bitbucket uses CodeMirror for syntax highlighting. For Bash or shell you can use sh, bash, or zsh. More information can be found at Configuring syntax highlighting for file extensions and Code mirror language modes.

As the other answers stated, you can place .gitignore within any directory in a Git repository. However, if you need to have a private version of .gitignore, you can add the rules to .git/info/exclude file.

An alternative to the proposed:

QString qs;
std::string current_locale_text = qs.toLocal8Bit().constData();

could be:

QString qs;
std::string current_locale_text = qPrintable(qs);

User::find(1) and User::first() return an instance.

User::where('id',1)->get and User::all() return a collection of instance.

call delete on an model instance will returns true/false

$user=User::find(1);
$user->delete(); //returns true/false

call delete on a collection of instance will returns a number which represents the number of the records had been deleted

//assume you have 10 users, id from 1 to 10;
$result=User::where('id','<',11)->delete(); //returns 11 (the number of the records had been deleted)

//lets call delete again
$result2=User::where('id','<',11)->delete(); //returns 0 (we have already delete the id<11 users, so this time we delete nothing, the result should be the number of the records had been deleted(0)  ) 

Also there are other delete methods, you can call destroy as a model static method like below

$result=User::destroy(1,2,3);
$result=User::destroy([1,2,3]);
$result=User::destroy(collect([1, 2, 3]));
//these 3 statement do the same thing, delete id =1,2,3 users, returns the number of the records had been deleted

One more thing ,if you are new to laravel ,you can use php artisan tinker to see the result, which is more efficient and then dd($result) , print_r($result);

You can use the DISTINCT keyword within the COUNT aggregate function:

SELECT COUNT(DISTINCT column_name) AS some_alias FROM table_name

This will count only the distinct values for that column.

I like to share a revelation that I had. When you build a project, Intellij Idea runs a java process that resides in its core(ex: C:\Program Files\JetBrains\IntelliJ IDEA 2020.3\jbr\bin). The "build process heap size", as mentioned by many others, changes the heap size of this java process. However, the main java process is triggered later by the Idea's java process, hence have different VM arguments. I noticed that the max heap size of this process is 1/3 of the Idea's java process, while min heap is the half of max(1/6). To round up:

When you set 9g heap on "build process heap size" the actual heap size for the compiler is max 3g and min 1,5g. And no need for restart is neccessary.

PS: tested on version 2020.3

I'm using firebird First of all, create a one column table named "NoTable" like this

CREATE TABLE NOTABLE 
(
  NOCOLUMN              INTEGER
);
INSERT INTO NOTABLE VALUES (0); -- You can put any value

now you can write this

select 'hello world' as name

from notable

you can add any column you want to be shown

This is jQuery Email Validation using Regex Expression. you can also use the same concept for AngularJS if you have idea of AngularJS.

var expression = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;

In MS-DOS COMMAND.COM shell, you have to use:

d:

cd \windows\movie

If by chance you actually meant "Windows command prompt" (which is not MS-DOS and not DOS at all), then you can use cd /d d:\windows\movie.

Based on responses and comments below, the following was the simple solution for my issue and THIS WORKED. Now my app, Match4app, is fully compatible with latest iOS versions!

1. Download Xcode 10.2 from a direct link (not from App Store). (Estimated Size: ~6Gb)
2. From the downloaded version just copy/paste the DeviceSupport/12.2 directory into "Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport"
3. You can discard the downloaded version now (we just need the small 12.2 directory!)

The return type of Html.RenderAction is void that means it directly renders the responses in View where the return type of Html.Action is MvcHtmlString You can catch its render view in controller and modify it by using following method

protected string RenderPartialViewToString(string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = ControllerContext.RouteData.GetRequiredString("action");

        ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            return sw.GetStringBuilder().ToString();
        }
    }

This will return the Html string of the View.

This is also applicable to Html.Partial and Html.RenderPartial

ng6+ -> 7.0

Update RxJS (depends on RxJS 6.3)

npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json

Remove rxjs-compat

Then update the core packages and Cli:

ng update @angular/cli @angular/core

(Optional: update Node.js to version 10 which is supported in NG7)

ng6+ (Cli 6.0+): features simplified commands

First, update your Cli

npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli

Then, update your core packages

ng update @angular/core

If you use RxJS, run

ng update rxjs

It will update RxJS to version 6 and install the rxjs-compat package under the hood.

If you run into build errors, try a manual install of:

npm i rxjs-compat
npm i @angular-devkit/build-angular

Lastly, check your version

ng v

Note on production build:

ng6 no longer uses intl in polyfills.ts

//remove them to avoid errors
import 'intl';
import 'intl/locale-data/jsonp/en';

ng5+ (Cli 1.5+)

npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router}@next [email protected] rxjs@'^5.5.2'
npm install [email protected] --save-exact

Note:

1. The supported Typescript version for Cli 1.6 as of writing is up to 2.5.3.
2. Using @next updates the package to beta, if available. Use @latest to get the latest non-beta version.

After updating both the global and local package, clear the cache to avoid errors:

npm cache verify (recommended)
npm cache clean (for older npm versions)

Here are the official references:

1. Updating the Cli
2. Updating the core packages core package.

You can also get the WINDOW width and height, avoiding browser toolbars and... (not just screen size).

To do this, use: window.innerWidth and window.innerHeight properties. See it at w3schools.

In most cases it will be the best way, in example, to display a perfectly centred floating modal dialog. It allows you to calculate positions on window, no matter which resolution orientation or window size is using the browser.

internal members are accessible within the assembly (only accessible in the same project)

private members are accessible within the same class

Example for Beginners

There are 2 projects in a solution (Project1, Project2) and Project1 has a reference to Project2.

• Public method written in Project2 will be accessible in Project2 and the Project1
• Internal method written in Project2 will be accessible in Project2 only but not in Project1
• private method written in class1 of Project2 will only be accessible to the same class. It will neither be accessible in other classes of Project 2 not in Project 1.

How about something like this ...

var l1 = new List<int>() { 1,2,3,4,5,2,2,2,4,4,4,1 };

var g = l1.GroupBy( i => i );

foreach( var grp in g )
{
  Console.WriteLine( "{0} {1}", grp.Key, grp.Count() );
}

Edit per comment: I will try and do this justice. :)

In my example, it's a Func<int, TKey> because my list is ints. So, I'm telling GroupBy how to group my items. The Func takes a int and returns the the key for my grouping. In this case, I will get an IGrouping<int,int> (a grouping of ints keyed by an int). If I changed it to (i => i.ToString() ) for example, I would be keying my grouping by a string. You can imagine a less trivial example than keying by "1", "2", "3" ... maybe I make a function that returns "one", "two", "three" to be my keys ...

private string SampleMethod( int i )
{
  // magically return "One" if i == 1, "Two" if i == 2, etc.
}

So, that's a Func that would take an int and return a string, just like ...

i =>  // magically return "One" if i == 1, "Two" if i == 2, etc. 

But, since the original question called for knowing the original list value and it's count, I just used an integer to key my integer grouping to make my example simpler.

There is a good workaround for this, now, by using jsdelivr.net.

Steps:

1. Find your link on GitHub, and click to the "Raw" version.
2. Copy the URL.
3. Change raw.githubusercontent.com to cdn.jsdelivr.net
4. Insert /gh/ before your username.
5. Remove the branch name.
6. (Optional) Insert the version you want to link to, as @version (if you do not do this, you will get the latest - which may cause long-term caching)

Examples:

http://raw.githubusercontent.com/<username>/<repo>/<branch>/path/to/file.js

Use this URL to get the latest version:

http://cdn.jsdelivr.net/gh/<username>/<repo>/path/to/file.js

Use this URL to get a specific version or commit hash:

http://cdn.jsdelivr.net/gh/<username>/<repo>@<version or hash>/path/to/file.js

For production environments, consider targeting a specific tag or commit-hash rather than the branch. Using the latest link may result in long-term caching of the file, causing your link to not be updated as you push new versions. Linking to a file by commit-hash or tag makes the link unique to version.

Why is this needed?

In 2013, GitHub started using X-Content-Type-Options: nosniff, which instructs more modern browsers to enforce strict MIME type checking. It then returns the raw files in a MIME type returned by the server, preventing the browser from using the file as-intended (if the browser honors the setting).

You won't always be able to simply generate the migration to already have the code you want. You can create an empty migration and then populate it with the code you need.

You can find information about how to accomplish different tasks in a migration here:

http://api.rubyonrails.org/classes/ActiveRecord/Migration.html

More specifically, you can see how to drop a table using the following approach:

drop_table :table_name

The error is telling you it cannot find the class because it is not available in your application.

If you are using Maven, make sure you have the dependency for jstl artifact:

<dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
</dependency>

If you are not using it, just make sure you include the JAR in your classpath. See this answer for download links.

You can use GAS, which is gcc's backend assembler:

A reference to an element will never look "falsy", so leaving off the explicit null check is safe.

Javascript will treat references to some values in a boolean context as false: undefined, null, numeric zero and NaN, and empty strings. But what getElementById returns will either be an element reference, or null. Thus if the element is in the DOM, the return value will be an object reference, and all object references are true in an if () test. If the element is not in the DOM, the return value would be null, and null is always false in an if () test.

It's harmless to include the comparison, but personally I prefer to keep out bits of code that don't do anything because I figure every time my finger hits the keyboard I might be introducing a bug :)

Note that those using jQuery should not do this:

if ($('#something')) { /* ... */ }

because the jQuery function will always return something "truthy" — even if no element is found, jQuery returns an object reference. Instead:

if ($('#something').length) { /* ... */ }

edit — as to checking the value of an element, no, you can't do that at the same time as you're checking for the existence of the element itself directly with DOM methods. Again, most frameworks make that relatively simple and clean, as others have noted in their answers.

For this problem, I have finally put a new <i> tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.

If user click on the "refresh" button, I trigger the onchange event of my select with :

const refreshEquipeEl = document.getElementById("refreshEquipe1");

function onClickRefreshEquipe(event){
    let event2 = new Event('change');
    equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;

This way, I don't need to try select the same option in my select.

A lot of people gave the basic answer but nobody pointed out that in C++ const defaults to static at namespace level (and some gave wrong information). See the C++98 standard section 3.5.3.

First some background:

Translation unit: A source file after the pre-processor (recursively) included all its include files.

Static linkage: A symbol is only available within its translation unit.

External linkage: A symbol is available from other translation units.

At namespace level

This includes the global namespace aka global variables.

static const int sci = 0; // sci is explicitly static
const int ci = 1;         // ci is implicitly static
extern const int eci = 2; // eci is explicitly extern
extern int ei = 3;        // ei is explicitly extern
int i = 4;                // i is implicitly extern
static int si = 5;        // si is explicitly static

At function level

static means the value is maintained between function calls.
The semantics of function static variables is similar to global variables in that they reside in the program's data-segment (and not the stack or the heap), see this question for more details about static variables' lifetime.

At class level

static means the value is shared between all instances of the class and const means it doesn't change.

Old question but this is a rather simple task that can be solved properly with core JS... without the Class abstraction of ES6. In fact as far as i can tell, the Class abstraction do not even solve this problem.

We can do this job both with the good old constructor function or even better with Object.create(). Lets go with the constructor first. This will essentially be a similar solution to georgebrock's answer which is criticised because all restaurants created by the Restaurant constructor will have the same private methods. I will try to overcome that limitation.

function restaurantFactory(name,menu){

  function Restaurant(name){
    this.name = name;
  }

  function prototypeFactory(menu){
    // This is a private function
    function calculateBill(item){
      return menu[item] || 0;
    }
    // This is the prototype to be
    return { constructor: Restaurant
           , askBill    : function(...items){
                            var cost = items.reduce((total,item) => total + calculateBill(item) ,0)
                            return "Thank you for dining at " + this.name + ". Total is: " + cost + "\n"
                          }
           , callWaiter : function(){
                            return "I have just called the waiter at " + this.name + "\n";
                          }
           }
  }

  Restaurant.prototype = prototypeFactory(menu);

  return new Restaurant(name,menu);
}

var menu = { water: 1
           , coke : 2
           , beer : 3
           , beef : 15
           , rice : 2
           },
    name = "Silver Scooop",
    rest = restaurantFactory(name,menu);

console.log(rest.callWaiter());
console.log(rest.askBill("beer", "beef"));

Now obviously we can not access menu from outside but we may easily rename the name property of a restaurant.

This can also be done with Object.create() in which case we skip the constructor function and simply do like var rest = Object.create(prototypeFactory(menu)) and add the name property to the rest object afterwards like rest.name = name.

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

Very small code to get Age:

<?php
    $dob='1981-10-07';
    $diff = (date('Y') - date('Y',strtotime($dob)));
    echo $diff;
?>

//output 35

Here is a shorter solution by AbacusUtil

Stream.of(input).toMap(e -> e.getKey().substring(subLength), 
                       e -> AttributeType.GetByName(e.getValue()));

Use this plugin http://multidatespickr.sourceforge.net

• Select date ranges.
• Pick multiple dates not in secuence.
• Define a maximum number of pickable dates.
• Define a range X days from where it is possible to select Y dates. Define unavailable dates
