A bit involved. Easiest would be to refer to this SQL Fiddle I created for you that produces the exact result. There are ways you can improve it for performance or other considerations, but this should hopefully at least be clearer than some alternatives.

The gist is, you get a canonical ranking of your data first, then use that to segment the data into groups, then find an end date for each group, then eliminate any intermediate rows. ROW_NUMBER() and CROSS APPLY help a lot in doing it readably.

EDIT 2019:

The SQL Fiddle does in fact seem to be broken, for some reason, but it appears to be a problem on the SQL Fiddle site. Here's a complete version, tested just now on SQL Server 2016:

CREATE TABLE Source
(
  EmployeeID int,
  DateStarted date,
  DepartmentID int
)

INSERT INTO Source
VALUES
(10001,'2013-01-01',001),
(10001,'2013-09-09',001),
(10001,'2013-12-01',002),
(10001,'2014-05-01',002),
(10001,'2014-10-01',001),
(10001,'2014-12-01',001)


SELECT *, 
  ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY DateStarted) AS EntryRank,
  newid() as GroupKey,
  CAST(NULL AS date) AS EndDate
INTO #RankedData
FROM Source
;

UPDATE #RankedData
SET GroupKey = beginDate.GroupKey
FROM #RankedData sup
  CROSS APPLY 
  (
    SELECT TOP 1 GroupKey
    FROM #RankedData sub 
    WHERE sub.EmployeeID = sup.EmployeeID AND
      sub.DepartmentID = sup.DepartmentID AND
      NOT EXISTS 
        (
          SELECT * 
          FROM #RankedData bot 
          WHERE bot.EmployeeID = sup.EmployeeID AND
            bot.EntryRank BETWEEN sub.EntryRank AND sup.EntryRank AND
            bot.DepartmentID <> sup.DepartmentID
        )
      ORDER BY DateStarted ASC
    ) beginDate (GroupKey);

UPDATE #RankedData
SET EndDate = nextGroup.DateStarted
FROM #RankedData sup
  CROSS APPLY 
  (
    SELECT TOP 1 DateStarted
    FROM #RankedData sub
    WHERE sub.EmployeeID = sup.EmployeeID AND
      sub.DepartmentID <> sup.DepartmentID AND
      sub.EntryRank > sup.EntryRank
    ORDER BY EntryRank ASC
  ) nextGroup (DateStarted);

SELECT * FROM 
(
SELECT *, ROW_NUMBER() OVER (PARTITION BY GroupKey ORDER BY EntryRank ASC) AS GroupRank FROM #RankedData
) FinalRanking
WHERE GroupRank = 1
ORDER BY EntryRank;

DROP TABLE #RankedData
DROP TABLE Source

You can use LIMIT 2,1 instead of WHERE row_number() = 3.

As the documentation explains, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return.

Keep in mind that it's an 0-based index. So, if you want the line number n, the first argument should be n-1. The second argument will always be 1, because you just want one row. For example, if you want the line number 56 of a table customer:

SELECT * FROM customer LIMIT 55,1

ROWID is a hidden column on Oracle tables, so, for SQL Server, build your own. Add a column called ROWID with a default value of NEWID().

From MySQL 8.0.0 and above you could natively use windowed functions.

1.4 What Is New in MySQL 8.0:

Window functions.

MySQL now supports window functions that, for each row from a query, perform a calculation using rows related to that row. These include functions such as RANK(), LAG(), and NTILE(). In addition, several existing aggregate functions now can be used as window functions; for example, SUM() and AVG().

ROW_NUMBER() over_clause :

Returns the number of the current row within its partition. Rows numbers range from 1 to the number of partition rows.

ORDER BY affects the order in which rows are numbered. Without ORDER BY, row numbering is indeterminate.

Demo:

CREATE TABLE Table1(
  id INT AUTO_INCREMENT PRIMARY KEY, col1 INT,col2 INT, col3 TEXT);

INSERT INTO Table1(col1, col2, col3)
VALUES (1,1,'a'),(1,1,'b'),(1,1,'c'),
       (2,1,'x'),(2,1,'y'),(2,2,'z');

SELECT 
    col1, col2,col3,
    ROW_NUMBER() OVER (PARTITION BY col1, col2 ORDER BY col3 DESC) AS intRow
FROM Table1;

DBFiddle Demo

You can start with a custom number and increment from there, for example you want to add a cheque number for each payment you can do:

select @StartChequeNumber = 3446;
SELECT 
((ROW_NUMBER() OVER(ORDER BY AnyColumn)) + @StartChequeNumber ) AS 'ChequeNumber'
,* FROM YourTable

will give the correct cheque number for each row.

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

by VB function:

Dim m_RowNr(3) as Variant
'
Function RowNr(ByVal strQName As String, ByVal vUniqValue) As Long
' m_RowNr(3)
' 0 - Nr
' 1 - Query Name
' 2 - last date_time
' 3 - UniqValue

If Not m_RowNr(1) = strQName Then
  m_RowNr(0) = 1
  m_RowNr(1) = strQName
ElseIf DateDiff("s", m_RowNr(2), Now) > 9 Then
  m_RowNr(0) = 1
ElseIf Not m_RowNr(3) = vUniqValue Then
  m_RowNr(0) = m_RowNr(0) + 1
End If

m_RowNr(2) = Now
m_RowNr(3) = vUniqValue
RowNr = m_RowNr(0)

End Function

Usage(without sorting option):

SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
From table A
Order By A.id

if sorting required or multiple tables join then create intermediate table:

 SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
 INTO table_with_Nr
 From table A
 Order By A.id

You can use MySQL variables to do it. Something like this should work (though, it consists of two queries).

SELECT 0 INTO @x;

SELECT itemID, 
       COUNT(*) AS ordercount, 
       (@x:=@x+1) AS rownumber 
FROM orders 
GROUP BY itemID 
ORDER BY ordercount DESC; 

That selects the row number per country code, account, and currency. So, the rows with country code "US", account "XYZ" and currency "$USD" will each get a row number assigned from 1-n; the same goes for every other combination of those columns in the result set.

This query is kind of funny, because the order by clause does absolutely nothing. All the rows in each partition have the same country code, account, and currency, so there's no point ordering by those columns. The ultimate row numbers assigned in this particular query will therefore be unpredictable.

Hope that helps...

You can use this for get first record where has clause

SELECT TOP(1) * , ROW_NUMBER() OVER(ORDER BY UserId) AS rownum 
FROM     Users 
WHERE    UserName = 'Joe'
ORDER BY rownum ASC

A Nuget solved my problem:Geocoding.Google 4.0.0. Install it so not necessary to write extra classes etc.

https://www.nuget.org/packages/Geocoding.Google/

Since it doesn't appear that anyone has mentioned it here yet, the new best way to manage HttpClient and HttpClientHandler in .NET Core 2.1 is using HttpClientFactory.

It solves most of the aforementioned issues and gotchas in a clean and easy-to-use way. From Steve Gordon's great blog post:

Add the following packages to your .Net Core (2.1.1 or later) project:

Microsoft.AspNetCore.All
Microsoft.Extensions.Http

Add this to Startup.cs:

services.AddHttpClient();

Inject and use:

[Route("api/[controller]")]
public class ValuesController : Controller
{
    private readonly IHttpClientFactory _httpClientFactory;

    public ValuesController(IHttpClientFactory httpClientFactory)
    {
        _httpClientFactory = httpClientFactory;
    }

    [HttpGet]
    public async Task<ActionResult> Get()
    {
        var client = _httpClientFactory.CreateClient();
        var result = await client.GetStringAsync("http://www.google.com");
        return Ok(result);
    }
}

Using Less

You could also consider to compile your own version. Try http://getbootstrap.com/customize/ (which has a apart section for the Navbars settings (Default navbar and Inverted Navbar)) or download your own copy from https://github.com/twbs/bootstrap.

You will find the navbar settings in variables.less. navbar.less is used to compile the navbar (depends on variables.less and mixins.less).

Copy the 'navbar-default section' and fill in your own color settings. Changing the variables in variables.less will be the easiest way (changing the default or inverse navbar won't be a problem because you have one navbar per page only).

You won't change all settings in most cases:

// Navbar
// -------------------------

// Basics of a navbar
@navbar-height:                    50px;
@navbar-margin-bottom:             @line-height-computed;
@navbar-default-color:             #777;
@navbar-default-bg:                #f8f8f8;
@navbar-default-border:            darken(@navbar-default-bg, 6.5%);
@navbar-border-radius:             @border-radius-base;
@navbar-padding-horizontal:        floor(@grid-gutter-width / 2);
@navbar-padding-vertical:          ((@navbar-height - @line-height-computed) / 2);

// Navbar links
@navbar-default-link-color:                #777;
@navbar-default-link-hover-color:          #333;
@navbar-default-link-hover-bg:             transparent;
@navbar-default-link-active-color:         #555;
@navbar-default-link-active-bg:            darken(@navbar-default-bg, 6.5%);
@navbar-default-link-disabled-color:       #ccc;
@navbar-default-link-disabled-bg:          transparent;

// Navbar brand label
@navbar-default-brand-color:               @navbar-default-link-color;
@navbar-default-brand-hover-color:         darken(@navbar-default-link-color, 10%);
@navbar-default-brand-hover-bg:            transparent;

// Navbar toggle
@navbar-default-toggle-hover-bg:           #ddd;
@navbar-default-toggle-icon-bar-bg:        #ccc;
@navbar-default-toggle-border-color:       #ddd;

You could also try http://twitterbootstrap3navbars.w3masters.nl/. This tool generates CSS code for your custom navbar. Optionally, you could also add gradient colors and borders to the navbar.

An empty string is a string with zero length or no character. Null is absence of data.

Apologies for my previously mixed up answer.

Here is how to do:

myTreeView.SelectedNode = myTreeNode;

(Update)

I have tested the code below and it works:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        treeView1.Nodes.Add("1", "1");
        treeView1.Nodes.Add("2", "2");
        treeView1.Nodes[0].Nodes.Add("1-1", "1-1");
        TreeNode treeNode = treeView1.Nodes[0].Nodes.Add("1-2", "1-3");
        treeView1.SelectedNode = treeNode;
        MessageBox.Show(treeNode.IsSelected.ToString());
    }


}

I answered a very similar question, and here is a way of doing this :

First, create a file where you would define your animations and export them. Just to make it more clear in your app.component.ts

In the following example, I used a max-height of the div that goes from 0px (when it's hidden), to 500px, but you would change that according to what you need.

This animation uses states (in and out), that will be toggle when we click on the button, which will run the animtion.

animations.ts

import { trigger, state, style, transition,
    animate, group, query, stagger, keyframes
} from '@angular/animations';

export const SlideInOutAnimation = [
    trigger('slideInOut', [
        state('in', style({
            'max-height': '500px', 'opacity': '1', 'visibility': 'visible'
        })),
        state('out', style({
            'max-height': '0px', 'opacity': '0', 'visibility': 'hidden'
        })),
        transition('in => out', [group([
            animate('400ms ease-in-out', style({
                'opacity': '0'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '0px'
            })),
            animate('700ms ease-in-out', style({
                'visibility': 'hidden'
            }))
        ]
        )]),
        transition('out => in', [group([
            animate('1ms ease-in-out', style({
                'visibility': 'visible'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '500px'
            })),
            animate('800ms ease-in-out', style({
                'opacity': '1'
            }))
        ]
        )])
    ]),
]

Then in your app.component, we import the animation and create the method that will toggle the animation state.

app.component.ts

import { SlideInOutAnimation } from './animations';

@Component({
  ...
  animations: [SlideInOutAnimation]
})
export class AppComponent  {
  animationState = 'in';

  ...

  toggleShowDiv(divName: string) {
    if (divName === 'divA') {
      console.log(this.animationState);
      this.animationState = this.animationState === 'out' ? 'in' : 'out';
      console.log(this.animationState);
    }
  }
}

And here is how your app.component.html would look like :

<div class="wrapper">
  <button (click)="toggleShowDiv('divA')">TOGGLE DIV</button>
  <div [@slideInOut]="animationState" style="height: 100px; background-color: red;">
  THIS DIV IS ANIMATED</div>
  <div class="content">THIS IS CONTENT DIV</div>
</div>

slideInOut refers to the animation trigger defined in animations.ts

Here is a StackBlitz example I have created : https://angular-muvaqu.stackblitz.io/

Side note : If an error ever occurs and asks you to add BrowserAnimationsModule, just import it in your app.module.ts:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [ ..., BrowserAnimationsModule ],
  ...
})

Modify the open_basedir settings in your hosting account and set them to none. Find the open_basedir setting given under 'PHP Settings' area of your Plesk/cPanel. Set it to 'none' from the dropdown given there. I have shown them in the Plesk panel picture.

I prefer the following code to wait for 2 seconds.

for(int i=0; i<2 && driver.findElements(By.id("textbox")).size()==0 ; i++){
   Thread.sleep(1000);
}

I prefer feature before layers, but I guess it depends on you project. Consider your forces:

• Dependencies
  Try minimize package dependencies, especially between features. Extract APIs if necessary.
• Team organization
  In some organizations teams work on features and in others on layers. This influence how code is organized, use it to formalize APIs or encourage cooperation.
• Deployment and versioning
  Putting everything into a module make deployment and versioning simpler, but bug fixing harder. Splitting things enable better control, scalability and availability.
• Respond to change
  Well organized code is much simpler to change than a big ball of mud.
• Size (people and lines of code)
  The bigger the more formalized/standardized it needs to be.
• Importance/quality
  Some code is more important than other. APIs should be more stable then the implementation. Therefore it needs to be clearly separated.
• Level of abstraction and entry point
  It should be possible for an outsider to know what the code is about, and where to start reading from looking at the package tree.

Example:

com/company/module
  + feature1/
    - MainClass          // The entry point for exploring
    + api/               // Public interface, used by other features
    + domain/
      - AggregateRoot
      + api/             // Internal API, complements the public, used by web
      + impl/ 
    + persistence/       
    + web/               // presentation layer 
    + services/          // Rest or other remote API 
    + support/            
  + feature2/
  + support/             // Any support or utils used by more than on feature
    + io
    + config
    + persistence
    + web

This is just an example. It is quite formal. For example it defines 2 interfaces for feature1. Normally that is not required, but could be a good idea if used differently by different people. You may let the internal API extend the public.

I do not like the 'impl' or 'support' names, but they help separate the less important stuff from the important (domain and API). When it comes to naming I like to be as concrete as possible. If you have a package called 'utils' with 20 classes, move StringUtils to support/string, HttpUtil to support/http and so on.

If you'd like to have the date in English:

from datetime import date
import calendar
my_date = date.today()
calendar.day_name[my_date.weekday()]  #'Wednesday'

In addition to Greg's answer, I would recommend to set the constructor private so that it is impossible to instantiate the class.

So in my humble opinion this is a more complete example based on Greg's one:

<?php

class Hello
{
    /**
     * Construct won't be called inside this class and is uncallable from
     * the outside. This prevents instantiating this class.
     * This is by purpose, because we want a static class.
     */
    private function __construct() {}
    private static $greeting = 'Hello';
    private static $initialized = false;

    private static function initialize()
    {
        if (self::$initialized)
            return;

        self::$greeting .= ' There!';
        self::$initialized = true;
    }

    public static function greet()
    {
        self::initialize();
        echo self::$greeting;
    }
}

Hello::greet(); // Hello There!


?>

Try using step="0.01", then it will step by a penny each time.

eg:

<input type="number" min="0.00" max="10000.00" step="0.01" />

Complicating a primitive with hidden fields to clarify whether False or Null is not recommended.

Checkbox isn't what you should be using -- it really only has one state: Checked. Otherwise, it could be anything.

When your database field is a nullable boolean (bool?), the UX should use 3-Radio Buttons, where the first button represents your "Checked", the second button represents "Not Checked" and the third button represents your null, whatever the semantics of null means. You could use a <select><option> drop down list to save real estate, but the user has to click twice and the choices aren't nearly as instantaneously clear.

  1     0      null 
True  False  Not Set
Yes   No     Undecided
Male  Female Unknown
On    Off    Not Detected

The RadioButtonList, defined as an extension named RadioButtonForSelectList, builds the radio buttons for you, including the selected/checked value, and sets the <div class="RBxxxx"> so you can use css to make your radio buttons go horizontal (display: inline-block), vertical, or in a table fashion (display: inline-block; width:100px;)

In the model (I'm using string, string for the dictionary definition as a pedagogical example. You can use bool?, string)

public IEnumerable<SelectListItem> Sexsli { get; set; }
       SexDict = new Dictionary<string, string>()
        {
                { "M", "Male"},
                { "F", "Female" },
                { "U", "Undecided" },

        };

        //Convert the Dictionary Type into a SelectListItem Type
        Sexsli = SexDict.Select(k =>
              new SelectListItem
              {
                  Selected = (k.Key == "U"),
                  Text = k.Value,
                  Value = k.Key.ToString()
              });

<fieldset id="Gender">
<legend id="GenderLegend" title="Gender - Sex">I am a</legend>
    @Html.RadioButtonForSelectList(m => m.Sexsli, Model.Sexsli, "Sex") 
        @Html.ValidationMessageFor(m => m.Sexsli)
</fieldset>

public static class HtmlExtensions
{
public static MvcHtmlString RadioButtonForSelectList<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression,
    IEnumerable<SelectListItem> listOfValues,
    String rbClassName = "Horizontal")
{
var metaData = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
var sb = new StringBuilder();

if (listOfValues != null)
{
    // Create a radio button for each item in the list 
    foreach (SelectListItem item in listOfValues)
    {
        // Generate an id to be given to the radio button field 
        var id = string.Format("{0}_{1}", metaData.PropertyName, item.Value);

        // Create and populate a radio button using the existing html helpers 
        var label = htmlHelper.Label(id, HttpUtility.HtmlEncode(item.Text));

        var radio = String.Empty;

        if (item.Selected == true)
        {
            radio = htmlHelper.RadioButtonFor(expression, item.Value, new { id = id, @checked = "checked" }).ToHtmlString();
        }
        else
        {
            radio = htmlHelper.RadioButtonFor(expression, item.Value, new { id = id }).ToHtmlString();

        }// Create the html string to return to client browser
        // e.g. <input data-val="true" data-val-required="You must select an option" id="RB_1" name="RB" type="radio" value="1" /><label for="RB_1">Choice 1</label> 

        sb.AppendFormat("<div class=\"RB{2}\">{0}{1}</div>", radio, label, rbClassName);
    }
}

return MvcHtmlString.Create(sb.ToString());
}
}

You can eventually extend the EL language by using the EL Functor, which will allow you to call any Java beans methods, even with parameters...

Tried and tested this works !

mkdir <directory name> ;  //Same directory name as the one you want to pull
cd <directory name>;
git remote add origin <GIT_URL>;
git checkout -b '<branch name>';
git config core.sparsecheckout true;
echo <directory name>/ >> .git/info/sparse-checkout;
git pull origin <pull branch name>

Hope this was helpful!

System.Decimal implements the IConvertable interface, which has a ToInt32() member.

Does calling System.Decimal.ToInt32() work for you?

Something like...

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

Which outputs

1
24
1440

or

System.out.println(Minutes.minutesBetween(yesterday, today).getMinutes());

Which is probably more what you're after

Specify the property in filter, of object on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "XYZ",
  "lastname": "ABC",
  "Address": "HOUSE NO-1, Example Street, Example Town"
},
{
  "firstname": "QWE",
  "lastname": "YUIKJH",
  "Address": "HOUSE NO-11, Example Street1, Example Town1"
}]

But you want to apply filter only on firstname

<input type = "text" ng-model = "first_name_model"/>
<div ng-repeat="user in users| filter:{ firstname: first_name_model}">

One important thing about git config:

git config has --local, --global and --system levels and corresponding files.

So you may use git config --local, git config --global and git config --system.

By default, git config will write to a local level if no configuration option is passed. Local configuration values are stored in a file that can be found in the repository's .git directory: .git/config

Global level configuration is user-specific, meaning it is applied to an operating system user. Global configuration values are stored in a file that is located in a user's home directory. ~/.gitconfig on Unix systems and C:\Users\<username>\.gitconfig on Windows.

System-level configuration is applied across an entire machine. This covers all users on an operating system and all repositories. The system level configuration file lives in a gitconfig file off the system root path. $(prefix)/etc/gitconfig on Linux systems. On Windows this file can be found in C:\ProgramData\Git\config.

So your option is to find that global .gitconfig file and edit it.

Or you can use git config --global --list.

This is exactly the line what you need.

In PrimeFaces 3.0, that style get applied on the generated inner <div> of the table cell, not on the <td> as you (and I) would expect. The following example should work out for you:

<p:dataTable styleClass="myTable">

with

.myTable td:nth-child(1) {
    width: 20px;
}

In PrimeFaces 3.5 and above, it should work exactly the way you coded and expected.

When you do not want to have the emails in the list that are in the database you'll can do the following:

select    u.name
        , u.EMAIL
        , a.emailadres
        , case when a.emailadres is null then 'Not exists'
               else 'Exists'
          end as 'Existence'
from      users u
          left join (          select 'email1' as emailadres
                     union all select 'email2'
                     union all select 'email3') a
            on  a.emailadres = u.EMAIL)

this way you'll get a result like

name | email  | emailadres | existence
-----|--------|------------|----------
NULL | NULL   | [email protected]    | Not exists
Jan  | [email protected] | [email protected]     | Exists

Using the IN or EXISTS operators are more heavy then the left join in this case.

Good luck :)

I would like to add that in case in you create local variables within the loop, they need to be expanded using the bang(!) notation as well. Extending the example at https://stackoverflow.com/a/2919699 above, if we want to create counter-based output filenames

set TEXT_T="myfile.txt"

set /a c=1

setlocal ENABLEDELAYEDEXPANSION

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
    set /a c=c+1
    set OUTPUT_FILE_NAME=output_!c!.txt
    echo Output file is !OUTPUT_FILE_NAME!
    echo %%i, !c!
)

endlocal

DateTime.UtcNow.ToString("s")

Returns something like 2008-04-10T06:30:00

UtcNow obviously returns a UTC time so there is no harm in:

string.Concat(DateTime.UtcNow.ToString("s"), "Z")

In your XML, you had used Textview, But in Java Code you had used EditText instead of TextView. If you change it into TextView you can set Text to to your TextView Object.

text = (TextView) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");

hope it will work.

mvn clean install -U

Solved my problem. Since the repos were cached, I needed to force it to get latest version.

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> #a vector of even numbers
> seq(0, 10, by=2) # Explicitly specifying "by" only to increase readability 
> [1]  0  2  4  6  8 10

Substrings with ${variablename:0:5} are a bash feature, not available in basic shells. Are you sure you're running this under bash? Check the shebang line (at the beginning of the script), and make sure it's #!/bin/bash, not #!/bin/sh. And make sure you don't run it with the sh command (i.e. sh scriptname), since that overrides the shebang.

Or, you may exclude the options in quotes:

FOR /F %%i IN (myfile.txt) DO ECHO %%i

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

It should be located C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log(date stamp)\

For AAD-B2C it is fairly simple. From Azure Portal with a B2C directory associated, go to your B2C directory (I added the "Azure AD B2C" to my portal's left menu). In the B2C directory click on "User flows (policies) directory menu item. In the policies pane click on one of your policies you previously added to select it. It should open a pane for the policy. Click "Properties". In the next pane is a section, "Token compatibility settings" which has a property "Issuer". Your AAD-B2C tenant GUID is contained in the URL.

try this for a months solution

StartDate <- strptime("14 January 2013", "%d %B %Y") 
EventDates <- strptime(c("26 March 2014"), "%d %B %Y") 
difftime(EventDates, StartDate) 

On Linux (and probably most Unix), there is no OS-level DNS caching unless nscd is installed and running. Even then, the DNS caching feature of nscd is disabled by default at least in Debian because it's broken. The practical upshot is that your linux system very very probably does not do any OS-level DNS caching.

You could implement your own cache in your application (like they did for Squid, according to diegows's comment), but I would recommend against it. It's a lot of work, it's easy to get it wrong (nscd got it wrong!!!), it likely won't be as easily tunable as a dedicated DNS cache, and it duplicates functionality that already exists outside your application.

If an end user using your software needs to have DNS caching because the DNS query load is large enough to be a problem or the RTT to the external DNS server is long enough to be a problem, they can install a caching DNS server such as Unbound on the same machine as your application, configured to cache responses and forward misses to the regular DNS resolvers.

The best I can come up with is:

int numberOfDigits = Convert.ToInt32(Math.Floor( Math.Log10( value ) ) );

int firstDigit = value / Math.Pow( 10, numberOfDigits );

Yes, #id selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.

However, for your example, since <script> comes before the elements, you need a document.ready handler, so it waits until the elements are in the DOM to go looking for them, like this:

<script>
  $(function() {
    $("#segement1,#segement2,#segement3").hide()
  });
</script>

<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>

Not only you can add a path, but you can add git diff --relative to get result relative to that folder.

git -C a/folder diff --relative

And with Git 2.28 (Q3 2020), the commands in the "diff" family learned to honor the "diff.relative" configuration variable.

See commit c28ded8 (22 May 2020) by Laurent Arnoud (spk).
^{(Merged by Junio C Hamano -- gitster -- in commit e34df9a, 02 Jun 2020)}

diff: add config option relative

^{Signed-off-by: Laurent Arnoud
Acked-by: Ðoàn Tr?n Công Danh}

The diff.relative boolean option set to true shows only changes in the current directory/value specified by the path argument of the relative option and shows pathnames relative to the aforementioned directory.

Teach --no-relative to override earlier --relative

Add for git-format-patch(1) options documentation --relative and --no-relative

The documentation now includes:

diff.relative:

If set to 'true', 'git diff' does not show changes outside of the directory and show pathnames relative to the current directory.

value_counts is a Series method rather than a DataFrame method (and you are trying to use it on a DataFrame, clean). You need to perform this on a specific column:

clean[column_name].value_counts()

It doesn't usually make sense to perform value_counts on a DataFrame, though I suppose you could apply it to every entry by flattening the underlying values array:

pd.value_counts(df.values.flatten())

I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

You could make the init method return this, and then chain the calls together, like this:

var userB = {
    init: function(nameParam) {
        this.id = MY_GLOBAL.nextId();
        this.name = nameParam;
        return this;
    },
    sayHello: function() {
        console.log('Hello '+ this.name);
    }
};

var bob = Object.create(userB).init('Bob');

I Think the simplest solutions is to add ngx-mask

npm i --save ngx-mask

then you can do

<input type='text' mask='(000) 000-0000' >

OR

<p>{{ phoneVar | mask: '(000) 000-0000' }} </p>

Here is what one can do for going on the way @iconoclast was wondering about in their comment on another answer.

use crontab for user or an /etc/crontab to create file /tmp/hour:

# m h dom mon dow user  command
0 * * * * root /usr/bin/touch /tmp/hour > /dev/null 2>&1

and then use this to run your command:

find /tmp/ -daystart -maxdepth 1 -not -newer /tmp/hour -type f -name "for_one_hour_files*" -exec do_something {} \;

I use Google Chart Tools https://developers.google.com/chart/ It's well documented and the charts look great. Being javascript, you can feed it json data via ajax.

// to string
String text = textField.getText();

// to JTextField
textField.setText(text);

You can also create a new text field: new JTextField(text)

Note that this is not conversion. You have two objects, where one has a property of the type of the other one, and you just set/get it.

Reference: javadocs of JTextField

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

I totally agree with the answers before. I just like to mention that the difference between expose and ports is part of the security concept in docker. It goes hand in hand with the networking of docker. For example:

Imagine an application with a web front-end and a database back-end. The outside world needs access to the web front-end (perhaps on port 80), but only the back-end itself needs access to the database host and port. Using a user-defined bridge, only the web port needs to be opened, and the database application doesn’t need any ports open, since the web front-end can reach it over the user-defined bridge.

This is a common use case when setting up a network architecture in docker. So for example in a default bridge network, not ports are accessible from the outer world. Therefor you can open an ingresspoint with "ports". With using "expose" you define communication within the network. If you want to expose the default ports you don't need to define "expose" in your docker-compose file.

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

Things that did not work for me:

• clicking the refresh icon (with or without shift)
• SHIFT-F5, CTRL-F5
• opening the page in an incognito window
• F12 (to open Dev tools) / (Dev tools) Settings / Disable cache (while dev tools is open)

What I mean by not working is: In the file system the .js file has been updated, but Chrome does not pick up the change. It means the page script executes with the old logic, Dev tools Scripts / ... / Compiled / ... shows the old .js content.

What does work for me:

• Close Chrome and re-open the page. After this Dev tools Scripts / ... / Compiled / ... shows updated .js content (matching the file system), and page scripts excute with updated logic.

There are three reasons why you shouldn't use for..in to iterate over array elements:

• for..in will loop over all own and inherited properties of the array object which aren't DontEnum; that means if someone adds properties to the specific array object (there are valid reasons for this - I've done so myself) or changed Array.prototype (which is considered bad practice in code which is supposed to work well with other scripts), these properties will be iterated over as well; inherited properties can be excluded by checking hasOwnProperty(), but that won't help you with properties set in the array object itself

• for..in isn't guaranteed to preserve element ordering

• it's slow because you have to walk all properties of the array object and its whole prototype chain and will still only get the property's name, ie to get the value, an additional lookup will be required

If you get this message after doing a commit in order to untrack file in the branch, try making some change in any file and perform commit. Apparently you can't make single commit which includes only untracking previously tracked file. Finally this post helped me solve whole problem https://help.github.com/articles/removing-files-from-a-repository-s-history/. I just had to remove file from repository history.

In addition to what other have said, you may also be interested to know that what in does is to call the list.__contains__ method, that you can define on any class you write and can get extremely handy to use python at his full extent.  

A dumb use may be:

>>> class ContainsEverything:
    def __init__(self):
        return None
    def __contains__(self, *elem, **k):
        return True


>>> a = ContainsEverything()
>>> 3 in a
True
>>> a in a
True
>>> False in a
True
>>> False not in a
False
>>>         

I have seen Big Theta, and I'm pretty sure I was taught the difference in school. I had to look it up though. This is what Wikipedia says:

Big O is the most commonly used asymptotic notation for comparing functions, although in many cases Big O may be replaced with Big Theta T for asymptotically tighter bounds.

Source: Big O Notation#Related asymptotic notation

I don't know why people use Big-O when talking formally. Maybe it's because most people are more familiar with Big-O than Big-Theta? I had forgotten that Big-Theta even existed until you reminded me. Although now that my memory is refreshed, I may end up using it in conversation. :)

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!

Overall, there appears to be no MIME type image/jpg. Yet, in practice, nearly all software handles image files named "*.jpg" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg could be many different things.

For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.

• sitepoint.com mime-types-complete-list (archived)
  • .jfif, .jfif-tbnl, .jpe, .jpeg, .jpg ? image/jpeg
  • .jfif, .jpe, .jpeg, .jpg ? image/pjpeg
• freeformatter.com mime-types (archived)
  • .jpeg, .jpg ? image/jpeg
  • .jpeg, .jpg ? image/x-citrix-jpeg
  • .pjpeg ? image/pjpeg
• IANA "Media Types" (formerly known as MIME types) lists (archived)
  (this document lists "names", not "file name extensions")
  • jpg not mentioned
  • jpeg ? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg¹³
  • JPEG ? video/JPEG
  • jpeg2000 ? video/jpeg2000
  • jpm ? image/jpm (JPEG 2000)
  • jpx ? image/jpx (JPEG 2000)
  • vnd.sealedmedia.softseal.jpg ? image/vnd.sealedmedia.softseal.jpg
• RFC 3745 MIME Type Registrations for JPEG 2000 (ISO/IEC 15444)
  • .jpg file extension not mentioned
  • .jpeg file extension not mentioned
  • .jp2, .jpg2 ? image/jp2 (JPEG 2000)⁹
  • .jpf, .jpx ? image/jpx (JPEG 2000 ISO-JPEG2000-2 encoded image data)¹⁰
  • .mj2, .mjp2 ? video/mj2 (Motion JPEG 2000)¹¹
  • .jpm, .jpgm ? image/jpm (JPEG 2000 profiles and extensions)¹²

These "complete lists" and RFC do not have MIME type image/jpg! But for MIME type image/jpeg some lists do have varying file name extensions (.jpeg, .jpg, …). Other lists do not mention image/jpeg.

Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.

Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf is preferred file extension for image/jpx but in IANA Media Types the name jpf is not present (and that IANA document references RFC 3745!).

Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.

Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?

The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg yet there exists the odd vnd.sealedmedia.softseal.jpg. File extension.JPEG is only known as a video type while file extension .jpeg is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000 is type video yet RFC 3745 considers JPEG 2000 an image type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg).

Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

Related question "List of ALL MimeTypes on the Planet, mapped to File Extensions?".

You'll want to listen for escape's keyCode (27) from the React SyntheticKeyBoardEvent onKeyDown:

const EscapeListen = React.createClass({
  handleKeyDown: function(e) {
    if (e.keyCode === 27) {
      console.log('You pressed the escape key!')
    }
  },

  render: function() {
    return (
      <input type='text'
             onKeyDown={this.handleKeyDown} />
    )
  }
})

Brad Colthurst's CodePen posted in the question's comments is helpful for finding key codes for other keys.

Update for PHP 7 (thanks shock_gone_wild)

PHP 7 introduces the so called null coalescing operator which simplifies the below statements to:

$var = $var ?? "default";

Before PHP 7

No, there is no special operator or special syntax for this. However, you could use the ternary operator:

$var = isset($var) ? $var : "default";

Or like this:

isset($var) ?: $var = 'default';

first = [1, 2, 3, 4, 5]
second = [6, 7, 8, 9, 10]
three = map(lambda x,y: x+y,first,second)
print three



Output 
[7, 9, 11, 13, 15]

I found it was impossible to assign a layout to the centralwidget until I had added at least one child beneath it. Then I could highlight the tiny icon with the red 'disabled' mark and then click on a layout in the Designer toolbar at top.

I have had this problem and I consider we are missing a well explained way of doing this programmatically without losing the already set filters.

Setting the length in XML:

As the accepted answer states correctly, if you want to define a fixed length to an EditText which you won't change further in the future just define in your EditText XML:

android:maxLength="10"     

Setting the length programmatically

To set the length programmatically you'll need to set it through an InputFilter. But if you create a new InputFilter and set it to the EditText you will lose all the other already defined filters (e.g. maxLines, inputType, etc) which you might have added either through XML or programatically.

So this is WRONG:

editText.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maxLength)});

To avoid losing previously added filters you need to get those filters, add the new one (maxLength in this case), and set the filters back to the EditText as follow:

Java

InputFilter[] editFilters = editText.getFilters();
InputFilter[] newFilters = new InputFilter[editFilters.length + 1];
System.arraycopy(editFilters, 0, newFilters, 0, editFilters.length);
newFilters[editFilters.length] = new InputFilter.LengthFilter(maxLength); 
editText.setFilters(newFilters);

Kotlin however made it easier for everyone, you also need to add the filter to the already existing ones but you can achieve that with a simple:

editText.filters += InputFilter.LengthFilter(maxLength)

import java.util.Scanner;
import java.util.*;
public class Main
{
  public static void main (String[]args) throws Exception
  {
    Scanner in = new Scanner (System.in);
    /*Prints out the welcome message at the top of the screen */
      System.out.printf ("%55s", "**WELCOME TO IDIOCY CENTRAL**\n");
      System.out.printf ("%55s", "=================================\n");

      String[] codes =
    {
    "G22", "K13", "I30", "S20"};

      System.out.printf ("%5s%5s%5s%5s\n", codes[0], codes[1], codes[2],
             codes[3]);
      System.out.printf ("Enter one of the above!\n");

    String usercode = in.nextLine ();
    for (int i = 0; i < codes.length; i++)
      {
    if (codes[i].equals (usercode))
      {
        System.out.printf ("What's the matter with you?\n");
      }
    else
      {
        System.out.printf ("Youda man!");
      }
      }

  }
}

It's important to note that the order of parameters is actually important to spring. The BindingResult needs to come right after the Form that is being validated. Likewise, the [optional] Model parameter needs to come after the BindingResult. Example:

Valid:

@RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  final BindingResult bindingResult,
                                  @RequestParam("pk") final long pk,
                                  final Model model) {
}

Not Valid:

RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  @RequestParam("pk") final long pk,
                                  final BindingResult bindingResult,
                                  final Model model) {
}

There are more api-friendly libraries than Net::HTTP, for example httparty:

require "httparty"
File.open("/tmp/my_file.flv", "wb") do |f| 
  f.write HTTParty.get("http://somedomain.net/flv/sample/sample.flv").parsed_response
end

Since you are summing up some int values together, there is no need to use BigInteger. long is enough for that. int is 32 bits, while long is 64 bits, that can contain the sum of all int values.

short recursive variant:

find . -type f -exec cat {} + | grep -c 'string'

Are you sure jQuery.HotKeys doesn't support the arrow keys? I've messed around with their demo before and observed left, right, up, and down working when I tested it in IE7, Firefox 3.5.2, and Google Chrome 2.0.172...

EDIT: It appears jquery.hotkeys has been relocated to Github: https://github.com/jeresig/jquery.hotkeys

You could use the following code where indentation doesn't matter:

>>> def fun():
        return ('{0} Here is a really long'
        ' sentence with {1}').format(3, 5)

You just need to enclose string in the parentheses.

There are ToUnixTime() and ToUnixTimeMs() methods in DateTimeExtensions class

DateTime.UtcNow.ToUnixTimeMs()

This situation occured if there are object in repository, which creates by current transaction.

Simple scenario:

1. checkout some directory two times, as DIR1 and DIR2
2. make 'svn mkdir test' in both
3. make commit from DIR1
4. try to make commit DIR2 (without svn up), SVN shall return this error

Same thing when adding same files from two working copies.

[edit sept 2020]: a snippet containing previous answer and added an arrow function

// a function call
yesterday = ( function(){this.setDate(this.getDate()-1); return this} )
            .call(new Date);
console.log(yesterday);

// an iife (immediately invoked function expression)
yesterday = function(d){ d.setDate(d.getDate()-1); return d}(new Date);
console.log(yesterday);

// oneliner using es6 arrow function
yesterday = ( d => new Date(d.setDate(d.getDate()-1)) )(new Date);
console.log(yesterday);

Addendum: @Thomas Mueller shows how to Execute SQL on Connection, but I sometimes just create and populate in the code, as suggested below.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

/** @see http://stackoverflow.com/questions/5225700 */
public class H2MemTest {

    public static void main(String[] args) throws Exception {
        Connection conn = DriverManager.getConnection("jdbc:h2:mem:", "sa", "");
        Statement st = conn.createStatement();
        st.execute("create table customer(id integer, name varchar(10))");
        st.execute("insert into customer values (1, 'Thomas')");
        Statement stmt = conn.createStatement();
        ResultSet rset = stmt.executeQuery("select name from customer");
        while (rset.next()) {
            String name = rset.getString(1);
            System.out.println(name);
        }
    }
}

The easiest way to do it using only Angular 2/4 template with no coding:

<nav class="navbar navbar-default" aria-expanded="false">
  <div class="container-wrapper">

    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" (click)="isCollapsed = !isCollapsed">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>

    <div class="navbar-collapse collapse no-transition" [attr.aria-expanded]="!isCollapsed" [ngClass]="{collapse: isCollapsed}">
      <ul class="nav navbar-nav" (click)="isCollapsed = !isCollapsed">
        <li [routerLinkActive]="['active']" [routerLinkActiveOptions]="{exact: true}"><a routerLink="/">Home</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/about">About</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/portfolio">Portfolio</a></li>
        <li [routerLinkActive]="['active']"><a routerLink="/contacts">Contacts</a></li>
      </ul>
    </div>

  </div>
</nav>

\b matches a word-boundary. \B matches non-word-boundaries, and is equivalent to [^\b](?!\b) _{^{(thanks to @Alan Moore for the correction!)}}. Both are zero-width.

See http://www.regular-expressions.info/wordboundaries.html for details. The site is extremely useful for many basic regex questions.

I understand this is an older question, but I would like to add another disadvantage of Single Page Applications:

If you build an API that returns results in a data language (such as XML or JSON) rather than a formatting language (like HTML), you are enabling greater application interoperability, for example, in business-to-business (B2B) applications. Such interoperability has great benefits but does allow people to write software to "mine" (or steal) your data. This particular disadvantage is common to all APIs that use a data language, and not to SPAs in general (indeed, an SPA that asks the server for pre-rendered HTML avoids this, but at the expense of poor model/view separation). This risk exposed by this disadvantage can be mitigated by various means, such as request limiting and connection blocking, etc.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

For Fedora:

# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"

# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

The s.insert(0, x) form is the most common.

Whenever you see it though, it may be time to consider using a collections.deque instead of a list.

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

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();
  }

}

Try putting the dates between # # for example:

#2013/4/4# and #2013/4/20#

It worked for me.

You might find Perl or Python useful to get data from the serial port. To send data to the server, the solution could be easy if the server is (let's say) an HTTP application or even a popular database. The solution would be not so easy if it is some custom/proprietary TCP application.

Subtract from another date object

var d = new Date();

d.setHours(d.getHours() - 2);

• Complete reference list for Date object

You CAN add css clases, and any type of attributes you need to blade template, try this:

{{ Form::open(array('url' => '/', 'method' => 'PUT', 'class'=>'col-md-12')) }}
.... wathever code here
{{ Form::close() }}

If you dont want to go the blade way you can add a hidden input. This is the form Laravel does, any way:

Note: Since HTML forms only support POST and GET, PUT and DELETE methods will be spoofed by automatically adding a _method hidden field to your form. (Laravel docs)

<form class="col-md-12" action="<?php echo URL::to('/');?>/post/<?=$post->postID?>" method="POST">

    <!-- Rendered blade HTML form use this hidden. Dont forget to put the form method to POST -->

    <input name="_method" type="hidden" value="PUT">

    <div class="form-group">
        <textarea type="text" class="form-control input-lg" placeholder="Text Here" name="post"><?=$post->post?></textarea>
    </div>

    <div class="form-group">
        <button class="btn btn-primary btn-lg btn-block" type="submit" value="Edit">Edit</button>
    </div>
</form>

%Started Program or Command% | taskkill /F /IM cmd.exe

Example:

notepad.exe | taskkill /F /IM cmd.exe

You shouldn't try to do that. Environment.CurrentDirectory gives you the path of the executable directory. This is consistent regardless of where the .exe file is. You shouldn't try to access a file that is assumed to be in a backwards relative location

I would suggest you move whatever resource you want to access into a local location. Of a system directory (such as AppData)

In order to get the MySQL Database item in the Choose Data Source window, one should install the MySQL for Visual Studio package available here (the last version today is 1.2.6):

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

We can use query instead of queryForObject, major difference between query and queryForObject is that query return list of Object(based on Row mapper return type) and that list can be empty if no data is received from database while queryForObject always expect only single object be fetched from db neither null nor multiple rows and in case if result is empty then queryForObject throws EmptyResultDataAccessException, I had written one code using query that will overcome the problem of EmptyResultDataAccessException in case of null result.

----------


public UserInfo getUserInfo(String username, String password) {
      String sql = "SELECT firstname, lastname,address,city FROM users WHERE id=? and pass=?";
      List<UserInfo> userInfoList = jdbcTemplate.query(sql, new Object[] { username, password },
              new RowMapper<UserInfo>() {
                  public UserInfo mapRow(ResultSet rs, int rowNum) throws SQLException {
                      UserInfo user = new UserInfo();
                      user.setFirstName(rs.getString("firstname"));
                      user.setLastName(rs.getString("lastname"));
                      user.setAddress(rs.getString("address"));
                      user.setCity(rs.getString("city"));

                      return user;
                  }
              });

      if (userInfoList.isEmpty()) {
          return null;
      } else {
          return userInfoList.get(0);
      }
  }

Using homebrew (recommended way):

To start:

brew services start mongodb-community

To stop:

brew services stop mongodb-community

new ArrayList( Arrays.asList( new String[]{"abc", "def"} ) );

If you want to load the font from the network or easily style it, you can use:

https://github.com/shellum/fontView

Example:

<!--Layout-->
<com.finalhack.fontview.FontView
        android:id="@+id/someFontIcon"
        android:layout_width="80dp"
        android:layout_height="80dp" />

//Java:
fontView.setupFont("http://blah.com/myfont.ttf", true, character, FontView.ImageType.CIRCLE);
fontView.addForegroundColor(Color.RED);
fontView.addBackgroundColor(Color.WHITE);

The bootstrap docs says about this:

Requires custom widths Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.

The default width of 100% as all form elements gets when they got the class form-control didn't apply if you use the form-inline class on your form.

You could take a look at the bootstrap.css (or .less, whatever you prefer) where you will find this part:

.form-inline {

  // Kick in the inline
  @media (min-width: @screen-sm-min) {
    // Inline-block all the things for "inline"
    .form-group {
      display: inline-block;
      margin-bottom: 0;
      vertical-align: middle;
    }

    // In navbar-form, allow folks to *not* use `.form-group`
    .form-control {
      display: inline-block;
      width: auto; // Prevent labels from stacking above inputs in `.form-group`
      vertical-align: middle;
    }
    // Input groups need that 100% width though
    .input-group > .form-control {
      width: 100%;
    }

    [...]
  }
}

Maybe you should take a look at input-groups, since I guess they have exactly the markup you want to use (working fiddle here):

<div class="row">
   <div class="col-lg-12">
    <div class="input-group input-group-lg">
      <input type="text" class="form-control input-lg" id="search-church" placeholder="Your location (City, State, ZIP)">
      <span class="input-group-btn">
        <button class="btn btn-default btn-lg" type="submit">Search</button>
      </span>
    </div>
  </div>
</div>

You may use following standard method for getting formatted Json

JsonReaderWriterFactory.CreateJsonWriter(Stream stream, Encoding encoding, bool ownsStream, bool indent, string indentChars)

Only set "indent==true"

Try something like this

    public readonly DataContractJsonSerializerSettings Settings = 
            new DataContractJsonSerializerSettings
            { UseSimpleDictionaryFormat = true };

    public void Keep<TValue>(TValue item, string path)
    {
        try
        {
            using (var stream = File.Open(path, FileMode.Create))
            {
                //var currentCulture = Thread.CurrentThread.CurrentCulture;
                //Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

                try
                {
                    using (var writer = JsonReaderWriterFactory.CreateJsonWriter(
                        stream, Encoding.UTF8, true, true, "  "))
                    {
                        var serializer = new DataContractJsonSerializer(type, Settings);
                        serializer.WriteObject(writer, item);
                        writer.Flush();
                    }
                }
                catch (Exception exception)
                {
                    Debug.WriteLine(exception.ToString());
                }
                finally
                {
                    //Thread.CurrentThread.CurrentCulture = currentCulture;
                }
            }
        }
        catch (Exception exception)
        {
            Debug.WriteLine(exception.ToString());
        }
    }

Pay your attention to lines

    var currentCulture = Thread.CurrentThread.CurrentCulture;
    Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
    ....
    Thread.CurrentThread.CurrentCulture = currentCulture;

For some kinds of xml-serializers you should use InvariantCulture to avoid exception during deserialization on the computers with different Regional settings. For example, invalid format of double or DateTime sometimes cause them.

For deserializing

    public TValue Revive<TValue>(string path, params object[] constructorArgs)
    {
        try
        {
            using (var stream = File.OpenRead(path))
            {
                //var currentCulture = Thread.CurrentThread.CurrentCulture;
                //Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

                try
                {
                    var serializer = new DataContractJsonSerializer(type, Settings);
                    var item = (TValue) serializer.ReadObject(stream);
                    if (Equals(item, null)) throw new Exception();
                    return item;
                }
                catch (Exception exception)
                {
                    Debug.WriteLine(exception.ToString());
                    return (TValue) Activator.CreateInstance(type, constructorArgs);
                }
                finally
                {
                    //Thread.CurrentThread.CurrentCulture = currentCulture;
                }
            }
        }
        catch
        {
            return (TValue) Activator.CreateInstance(typeof (TValue), constructorArgs);
        }
    }

Thanks!

Just include this script

http://code.jquery.com/jquery-migrate-1.0.0.js

after you include your jquery javascript file.

This code should do the same as your new routine, working with the correct multi-dimensional array..

 $arr = array(
  'string1' => array('a' => '', 'b' => '', 'c' => ''),
  'string2' => array('a' => '', 'b' => '', 'c' => ''),
  'string3' => array('a' => '', 'b' => '', 'c' => '')
 );

 echo 'Index of "string2" = '. array_search('string2', array_keys($arr));

You can also use attr along with style:

$('#message').attr("style", "width:550; height:300; font-size:8px" );

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Here is a swift version:

struct iOSVersion {
    static let SYS_VERSION_FLOAT = (UIDevice.currentDevice().systemVersion as NSString).floatValue
    static let iOS7 = (Version.SYS_VERSION_FLOAT < 8.0 && Version.SYS_VERSION_FLOAT >= 7.0)
    static let iOS8 = (Version.SYS_VERSION_FLOAT >= 8.0 && Version.SYS_VERSION_FLOAT < 9.0)
    static let iOS9 = (Version.SYS_VERSION_FLOAT >= 9.0 && Version.SYS_VERSION_FLOAT < 10.0)
}

Usage:

if iOSVersion.iOS8 {
    //Do iOS8 code here
}

Running rails dev:cache in my console fixed this for me! (Rails 6)

I think it might be something to do with Turbolinks, but CSRF only seems to work when local caching is enabled.

In a case statement, a , is the equivalent of || in an if statement.

case car
   when 'toyota', 'lexus'
      # code
end

Some other things you can do with a Ruby case statement

The shortest way I know to generate valid json from array of integers is

let json = `[${cars}]`

for more general object/array use JSON.stringify(cars) (for object with circular references use this)

let cars = [1,2,3]; cars.push(4,5,6);

let json = `[${cars}]`;

console.log(json);
console.log(JSON.parse(json)); // json validation

NSMutableAttributedString *text = [self.myUILabel.attributedText mutableCopy];
[text addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(0, text.length)];
self.myUILabel.attributedText = text;

This method seems ok in all browsers, if you set the onclick with a jQuery event:

<a href="javascript:;">Click me!</a>

As said before, href="#" with change the url hash and can trigger data re/load if you use a History (or ba-bbq) JS plugin.

Static memory allocation: The compiler allocates the required memory space for a declared variable.By using the address of operator,the reserved address is obtained and this address may be assigned to a pointer variable.Since most of the declared variable have static memory,this way of assigning pointer value to a pointer variable is known as static memory allocation. memory is assigned during compilation time.

Dynamic memory allocation: It uses functions such as malloc( ) or calloc( ) to get memory dynamically.If these functions are used to get memory dynamically and the values returned by these functions are assingned to pointer variables, such assignments are known as dynamic memory allocation.memory is assined during run time.

the problem is blade, try this

<i class="fa" v-bind:class="['{{content['cravings']}}' ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline']"></i>

If you have already installed nodejs and still getting this error. npm: command not found..

Microsoft recognized the future web open source paradigm and decided to open .NET to other operating systems. .NET Core is a .NET Framework for Mac and Linux. It is a “lightweight” .NET Framework, so some features/libraries are missing.

On Windows, I would still run .NET Framework and Visual Studio 2015. .NET Core is more friendly with the open source world like Node.js, npm, Yeoman, Docker, etc.

You can develop full-fledged web sites and RESTful APIs on Mac or Linux with Visual Studio Code + .NET Core which wasn't possible before. So if you love Mac or Ubuntu and you are a .NET developer then go ahead and set it up.

For Mono vs. .NET Core, Mono was developed as a .NET Framework for Linux which is now acquired by Microsoft (company called Xamarin) and used in mobile development. Eventually, Microsoft may merge/migrate Mono to .NET Core. I would not worry about Mono right now.

Try this one in your css document,

-fx-background-color : #ffaadd;

or

-fx-base : #ffaadd; 

Also, you can set background color on your object with this code directly.

yourPane.setBackground(new Background(new BackgroundFill(Color.DARKGREEN, CornerRadii.EMPTY, Insets.EMPTY)));

There are multiple number groups and some particular numbers that will never be allocated:

• Numbers with all zeros in any digit group (000-xx-####, ###-00-####, ###-xx-0000).
• Numbers with an area group (first three digits) of 666 or any of 900-999.
• Numbers that have been misused in any way, such as the well known 078-05-1120.

Consider using one of these (the obviously invalid 000-00-0000 would be a good one IMO).

Just change it to

If you are checking your mongodb logs and you are getting such an error then just follow steps as i did. It occurs due to permission issues with your /data/db directory. I am using ubuntu16.04 and I find solution with running two simple commands as follow.

Step 1: Give permission to /data/db directory:

sudo chmod -R 0777 /data/db

Step 2: Try to start mongod service as :

sudo service mongod start

Step 3: Check status of mongod service:

sudo service mongod status

Just use the below code. It will shadow surround the entire DIV

-webkit-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
-moz-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);

Hope this will work

Try this....

ul.list-group li {
     padding-left: 13px;
     position: relative;
}

ul.list-group li:before {
     left: 0 !important;
     position: absolute;
}

The above did not work for me but this did

<%= link_to "text_to_show_in_url", action_controller_path(:gender => "male", :param2=> "something_else") %>

I was getting this error with Laravel Sanctum. I fixed it by adding \Illuminate\Session\Middleware\StartSession::class, to the api middleware group in Kernel.php, but I later figured out this "worked" because my authentication routes were added in api.php instead of web.php, so Laravel was using the wrong auth guard.

I moved these routes here into web.php and then they started working properly with the AuthenticatesUsers.php trait:

Route::group(['middleware' => ['guest', 'throttle:10,5']], function () {
    Route::post('register', 'Auth\RegisterController@register')->name('register');
    Route::post('login', 'Auth\LoginController@login')->name('login');

    Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
    Route::post('password/reset', 'Auth\ResetPasswordController@reset');

    Route::post('email/verify/{user}', 'Auth\VerificationController@verify')->name('verification.verify');
    Route::post('email/resend', 'Auth\VerificationController@resend');

    Route::post('oauth/{driver}', 'Auth\OAuthController@redirectToProvider')->name('oauth.redirect');
    Route::get('oauth/{driver}/callback', 'Auth\OAuthController@handleProviderCallback')->name('oauth.callback');
});

Route::post('logout', 'Auth\LoginController@logout')->name('logout');

I figured out the problem after I got another weird error about RequestGuard::logout() does not exist.

It made me realize that my custom auth routes are calling methods from the AuthenticatesUsers trait, but I wasn't using Auth::routes() to accomplish it. Then I realized Laravel uses the web guard by default and that means routes should be in routes/web.php.

This is what my settings look like now with Sanctum and a decoupled Vue SPA app:

Kernel.php

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],

    'api' => [
        EnsureFrontendRequestsAreStateful::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'throttle:60,1',
    ],
];

Note: With Laravel Sanctum and same-domain Vue SPA, you use httpOnly cookies for session cookie, and remember me cookie, and unsecure cookie for CSRF, so you use the web guard for auth, and every other protected, JSON-returning route should use auth:sanctum middleware.

config/auth.php

'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],

...

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
        'hash' => false,
    ],
],

Then you can have unit tests such as this, where critically, Auth::check(), Auth::user(), and Auth::logout() work as expected with minimal config and maximal usage of AuthenticatesUsers and RegistersUsers traits.

Here are a couple of my login unit tests:

TestCase.php

/**
 * Creates and/or returns the designated regular user for unit testing
 *
 * @return \App\User
 */
public function user() : User
{
    $user = User::query()->firstWhere('email', '[email protected]');

    if ($user) {
        return $user;
    }

    // User::generate() is just a wrapper around User::create()
    $user = User::generate('Test User', '[email protected]', self::AUTH_PASSWORD);

    return $user;
}

/**
 * Resets AuthManager state by logging out the user from all auth guards.
 * This is used between unit tests to wipe cached auth state.
 *
 * @param array $guards
 * @return void
 */
protected function resetAuth(array $guards = null) : void
{
    $guards = $guards ?: array_keys(config('auth.guards'));

    foreach ($guards as $guard) {
        $guard = $this->app['auth']->guard($guard);

        if ($guard instanceof SessionGuard) {
            $guard->logout();
        }
    }

    $protectedProperty = new \ReflectionProperty($this->app['auth'], 'guards');
    $protectedProperty->setAccessible(true);
    $protectedProperty->setValue($this->app['auth'], []);
}

LoginTest.php

protected $auth_guard = 'web';

/** @test */
public function it_can_login()
{
    $user = $this->user();

    $this->postJson(route('login'), ['email' => $user->email, 'password' => TestCase::AUTH_PASSWORD])
        ->assertStatus(200)
        ->assertJsonStructure([
            'user' => [
                ...expectedUserFields,
            ],
        ]);

    $this->assertEquals(Auth::check(), true);
    $this->assertEquals(Auth::user()->email, $user->email);
    $this->assertAuthenticated($this->auth_guard);
    $this->assertAuthenticatedAs($user, $this->auth_guard);

    $this->resetAuth();
}

/** @test */
public function it_can_logout()
{
    $this->actingAs($this->user())
        ->postJson(route('logout'))
        ->assertStatus(204);

    $this->assertGuest($this->auth_guard);

    $this->resetAuth();
}

I overrided the registered and authenticated methods in the Laravel auth traits so that they return the user object instead of just the 204 OPTIONS:

public function authenticated(Request $request, User $user)
{
    return response()->json([
        'user' => $user,
    ]);
}

protected function registered(Request $request, User $user)
{
    return response()->json([
        'user' => $user,
    ]);
}

Look at the vendor code for the auth traits. You can use them untouched, plus those two above methods.

• vendor/laravel/ui/auth-backend/RegistersUsers.php
• vendor/laravel/ui/auth-backend/AuthenticatesUsers.php

Here is my Vue SPA's Vuex actions for login:

async login({ commit }, credentials) {
    try {
        const { data } = await axios.post(route('login'), {
            ...credentials,
            remember: credentials.remember || undefined,
        });

        commit(FETCH_USER_SUCCESS, { user: data.user });
        commit(LOGIN);

        return commit(CLEAR_INTENDED_URL);
    } catch (err) {
        commit(LOGOUT);
        throw new Error(`auth/login# Problem logging user in: ${err}.`);
    }
},

async logout({ commit }) {
    try {
        await axios.post(route('logout'));

        return commit(LOGOUT);
    } catch (err) {
        commit(LOGOUT);

        throw new Error(`auth/logout# Problem logging user out: ${err}.`);
    }
},

It took me over a week to get Laravel Sanctum + same-domain Vue SPA + auth unit tests all working up to my standard, so hopefully my answer here can help save others time in the future.

The entire transmission, including the query string, the whole URL, and even the type of request (GET, POST, etc.) is encrypted when using HTTPS.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

Here is a copy/paste solution. I also recommend reading and voting for @Konstantino's answer even though it doesn't provider any code. The initialization vector (IV) is like a salt - it doesn't have to be kept secret. I am new to GCM and apparently AAD is optional and only used in certain circumstances. Set the key in the environment variable SECRET_KEY_BASE. Use something like KeePass to generate a 32 character password. This solution is modeled after my Ruby solution.

    public static String encrypt(String s) {
        try {
            byte[] input = s.getBytes("UTF-8");
            String keyString = System.getProperty("SECRET_KEY_BASE", System.getenv("SECRET_KEY_BASE"));
            if (keyString == null || keyString.length() == 0) {
                Logger.error(Utils.class, "encrypt()", "$SECRET_KEY_BASE is not set.");
                return null;
            }
            byte[] keyBytes = keyString.getBytes("UTF-8");
            SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES");
            // generate IV
            SecureRandom secureRandom = SecureRandom.getInstanceStrong();
            Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
            byte[] ivBytes = new byte[cipher.getBlockSize()];
            secureRandom.nextBytes(ivBytes);
            GCMParameterSpec gcmSpec = new GCMParameterSpec(96, ivBytes); // 96 bit tag length
            cipher.init(Cipher.ENCRYPT_MODE, keySpec, gcmSpec);
            // generate AAD
//          byte[] aadBytes = new byte[cipher.getBlockSize()];
//          secureRandom.nextBytes(aadBytes);
//          cipher.updateAAD(aadBytes);
            // encrypt
            byte[] encrypted = cipher.doFinal(input);
            byte[] returnBytes = new byte[ivBytes.length + encrypted.length];
//          byte[] returnBytes = new byte[ivBytes.length + aadBytes.length + encrypted.length];
            System.arraycopy(ivBytes, 0, returnBytes, 0, ivBytes.length);
//          System.arraycopy(aadBytes, 0, returnBytes, ivBytes.length, aadBytes.length);
            System.arraycopy(encrypted, 0, returnBytes, ivBytes.length, encrypted.length);
//          System.arraycopy(encrypted, 0, returnBytes, ivBytes.length+aadBytes.length, encrypted.length);
            String encryptedString = Base64.getEncoder().encodeToString(returnBytes);
            return encryptedString;
        } catch (UnsupportedEncodingException | NoSuchAlgorithmException | NoSuchPaddingException | InvalidKeyException | 
                InvalidAlgorithmParameterException | IllegalBlockSizeException | BadPaddingException e) {
            Logger.error(Utils.class, "encrypt()", "Could not encrypt string: " + e.getMessage());
            return null;
        }
    }

    public static String decrypt(String s) {
        if (s == null || s.length() == 0) return "";
        try {
            byte[] encrypted = Base64.getDecoder().decode(s);
            String keyString = System.getProperty("SECRET_KEY_BASE", System.getenv("SECRET_KEY_BASE"));
            if (keyString == null || keyString.length() == 0) {
                Logger.error(Utils.class, "encrypt()", "$SECRET_KEY_BASE is not set.");
                return null;
            }
            byte[] keyBytes = keyString.getBytes("UTF-8");
            SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES");
            Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
            byte[] ivBytes = new byte[cipher.getBlockSize()];
            System.arraycopy(encrypted, 0, ivBytes, 0, ivBytes.length);
            GCMParameterSpec gcmSpec = new GCMParameterSpec(96, ivBytes);
            cipher.init(Cipher.DECRYPT_MODE, keySpec, gcmSpec);
//          cipher.updateAAD(encrypted, ivBytes.length, cipher.getBlockSize());
            byte[] decrypted = cipher.doFinal(encrypted, cipher.getBlockSize(), encrypted.length - cipher.getBlockSize());
//          byte[] decrypted = cipher.doFinal(encrypted, cipher.getBlockSize()*2, encrypted.length - cipher.getBlockSize()*2);
            String decryptedString = new String(decrypted, "UTF-8");
            return decryptedString;
        } catch (NoSuchAlgorithmException | NoSuchPaddingException | UnsupportedEncodingException | InvalidKeyException | 
                InvalidAlgorithmParameterException | IllegalBlockSizeException | BadPaddingException e) {
            Logger.error(Utils.class, "decrypt()", "Could not decrypt string: " + e.getMessage());
            return null;
        }
    }

Here is an example:

    String s = "This is a test.";
    String enc = Utils.encrypt(s);
    System.out.println(enc);
    // fQHfYjbD+xAuN5XzH2ojk/EWNeKXUrKRSfx8LU+5dpuKkM/pueCMBjKCZw==
    String dec = Utils.decrypt(enc);
    System.out.println(dec);
    // This is a test.

For new you should use delete. For new[] use delete[]. Your second variant is correct.

Sorry, but all the answers are difficult to understand for me as a beginner in graphics...

After some fiddling, this is working for me and it is easy to reason about.

@Override
public void draw(Graphics2D g) {
    AffineTransform tr = new AffineTransform();
    // X and Y are the coordinates of the image
    tr.translate((int)getX(), (int)getY());
    tr.rotate(
            Math.toRadians(this.rotationAngle),
            img.getWidth() / 2,
            img.getHeight() / 2
    );

    // img is a BufferedImage instance
    g.drawImage(img, tr, null);
}

I suppose that if you want to rotate a rectangular image this method wont work and will cut the image, but I thing you should create square png images and rotate that.

Had this issue on Python 2.7.9, solved by updating to Python 2.7.10 (unreleased when this question was asked and answered).

A lot of folks get confused about the difference between char* and char[] in conjunction with string literals in C. When you write:

char *foo = "hello world";

...you are actually pointing foo to a constant block of memory (in fact, what the compiler does with "hello world" in this instance is implementation-dependent.)

Using char[] instead tells the compiler that you want to create an array and fill it with the contents, "hello world". foo is the a pointer to the first index of the char array. They both are char pointers, but only char[] will point to a locally allocated and mutable block of memory.

Setting this attribute to ObjectMapper instance works,

objectMapper.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);

Another approach would be to add the following line to package.json dependencies:

"package-name": "user/repo#branch"

For example:

"dependencies": {
    ... other dependencies ...

    "react-native": "facebook/react-native#master"
}

And then do npm install or yarn install

I know this is an old question but I thought I would provide an example using the srcdoc attribute as this is now widely supported and this is question is viewed often.

Using the srcdoc attribute, you can provide inline HTML to embed. It overrides the src attribute if supported. The browser will fall back to the src attribute if unsupported.

I would also recommend using the sandbox attribute to apply extra restrictions to the content in the frame. This is especially important if the HTML is not your own.

const iframe = document.createElement('iframe');_x000D_
const html = '<body>Foo</body>';_x000D_
iframe.srcdoc = html;_x000D_
iframe.sandbox = '';_x000D_
document.body.appendChild(iframe);

If you need to support older browsers, you can check for srcdoc support and fallback to one of the other methods from other answers.

function setIframeHTML(iframe, html) {_x000D_
  if (typeof iframe.srcdoc !== 'undefined') {_x000D_
    iframe.srcdoc = html;_x000D_
  } else {_x000D_
    iframe.sandbox = 'allow-same-origin';_x000D_
    iframe.contentWindow.document.open();_x000D_
    iframe.contentWindow.document.write(html);_x000D_
    iframe.contentWindow.document.close();_x000D_
  }_x000D_
}_x000D_
_x000D_
var iframe = document.createElement('iframe');_x000D_
iframe.sandbox = '';_x000D_
var html = '<body>Foo</body>';_x000D_
_x000D_
document.body.appendChild(iframe);_x000D_
setIframeHTML(iframe, html);

set the body max-width:110%; and the make the width on the header 110% it will leave a small margin on left that you can fiX with margin-left: -8px; margin-top: -10px;

I know this has been answered but wanted to provide alternate solution for anyone in the future:

You can use .loc to subset the dataframe by only values that are notnull(), and then subset out the 'x' column only. Take that same vector, and apply(int) to it.

If column x is float:

df.loc[df['x'].notnull(), 'x'] = df.loc[df['x'].notnull(), 'x'].apply(int)

In 2012, use the python requests library

>>> import requests
>>> 
>>> url = "http://download.thinkbroadband.com/10MB.zip"
>>> r = requests.get(url)
>>> print len(r.content)
10485760

You can run pip install requests to get it.

Requests has many advantages over the alternatives because the API is much simpler. This is especially true if you have to do authentication. urllib and urllib2 are pretty unintuitive and painful in this case.

People have expressed admiration for the progress bar. It's cool, sure. There are several off-the-shelf solutions now, including tqdm:

from tqdm import tqdm
import requests

url = "http://download.thinkbroadband.com/10MB.zip"
response = requests.get(url, stream=True)

with open("10MB", "wb") as handle:
    for data in tqdm(response.iter_content()):
        handle.write(data)

This is essentially the implementation @kvance described 30 months ago.

It’s very old, but it is still useful.

A more elegant way to convert json to csv is to use the map function without any framework:

var json = json3.items
var fields = Object.keys(json[0])
var replacer = function(key, value) { return value === null ? '' : value } 
var csv = json.map(function(row){
  return fields.map(function(fieldName){
    return JSON.stringify(row[fieldName], replacer)
  }).join(',')
})
csv.unshift(fields.join(',')) // add header column
 csv = csv.join('\r\n');
console.log(csv)

Output:

Update ES6 (2016)

Use this less dense syntax and also JSON.stringify to add quotes to strings while keeping numbers unquoted:

const items = json3.items
const replacer = (key, value) => value === null ? '' : value // specify how you want to handle null values here
const header = Object.keys(items[0])
const csv = [
  header.join(','), // header row first
  ...items.map(row => header.map(fieldName => JSON.stringify(row[fieldName], replacer)).join(','))
].join('\r\n')

console.log(csv)

This is probably the best way, since it’s reliable and works on old browsers:

function indexOfMax(arr) {
    if (arr.length === 0) {
        return -1;
    }

    var max = arr[0];
    var maxIndex = 0;

    for (var i = 1; i < arr.length; i++) {
        if (arr[i] > max) {
            maxIndex = i;
            max = arr[i];
        }
    }

    return maxIndex;
}

There’s also this one-liner:

let i = arr.indexOf(Math.max(...arr));

It performs twice as many comparisons as necessary and will throw a RangeError on large arrays, though. I’d stick to the function.

To clarify, a database created under SQL Server 2008 R2 was being opened in an instance of SQL Server 2008 (the version prior to R2). The solution for me was to simply perform an upgrade installation of SQL Server 2008 R2. I can only speak for the Express edition, but it worked.

Oddly, though, the Web Platform Installer indicated that I had Express R2 installed. The better way to tell is to ask the database server itself:

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

The main difference between struct and class is that in struct you can only declare data variables of different data types while in class you can declare data variables,member functions and thus you can manipulate data variables through functions.

-> another handy thing that i find in class vs struct is that while implementing files in a program if you want to make some operations of a struct again and again on every new set of operations you need to make a separate function and you need to pass object of struct after reading it from the file so as to make some operations on it . while in class if you make a function that does some operations on the data needed everytime..its easy you just have to read object from file and call the function..

But it depennds on the programmer which way he/she finds suitable...according to me i prefer class everytime just because it supports OOPs and thats the reason it is implemented in almost every languages and its the wonderful feature of all time programming ;-)

And yeah the most unforgotten difference i forgot to mention is that class supports data hiding and also supports operations that are performed on built in data types while struct doesnt !

Oh ok - now I get it. You can ignore this one - the XML for this is just not correct - the packages-element is indeed not declared (there is no reference to a schema or whatever). I think this is a known minor bug that won't do a thing because only NuGet will use this.

<a [routerLink]="['/search', { tag: 'fish' } ]">A link</a>

In the above I am using the link parameter array see sources below for more information.

From the jQuery documentation - http://api.jquery.com/jQuery.ajax/

contentType When sending data to the server, use this content type.

dataType The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response

"text": A plain text string.

So you want contentType to be application/json and dataType to be text:

$.ajax({
    type : "POST",
    url : /v1/user,
    dataType : "text",
    contentType: "application/json",
    data : dataAttribute,
    success : function() {

    },
    error : function(error) {

    }
});

I think my answer will be more technical, but not different as the others present the same thing using different techniques.
So, first things first, the solution to this problem is the use of a design pattern known as "observer", it let's you decouple your data from your presentation, making the change in one thing be broadcasted to their listeners, but in this case it's made two-way.

For the DOM to JS way

To bind the data from the DOM to the js object you may add markup in the form of data attributes (or classes if you need compatibility), like this:

<input type="text" data-object="a" data-property="b" id="b" class="bind" value=""/>
<input type="text" data-object="a" data-property="c" id="c" class="bind" value=""/>
<input type="text" data-object="d" data-property="e" id="e" class="bind" value=""/>

This way it can be accessed via js using querySelectorAll (or the old friend getElementsByClassName for compatibility).

Now you can bind the event listening to the changes in to ways: one listener per object or one big listener to the container/document. Binding to the document/container will trigger the event for every change made in it or it's child, it willhave a smaller memory footprint but will spawn event calls.
The code will look something like this:

//Bind to each element
var elements = document.querySelectorAll('input[data-property]');

function toJS(){
    //Assuming `a` is in scope of the document
    var obj = document[this.data.object];
    obj[this.data.property] = this.value;
}

elements.forEach(function(el){
    el.addEventListener('change', toJS, false);
}

//Bind to document
function toJS2(){
    if (this.data && this.data.object) {
        //Again, assuming `a` is in document's scope
        var obj = document[this.data.object];
        obj[this.data.property] = this.value;
    }
}

document.addEventListener('change', toJS2, false);

For the JS do DOM way

You will need two things: one meta-object that will hold the references of witch DOM element is binded to each js object/attribute and a way to listen to changes in objects. It is basically the same way: you have to have a way to listen to changes in the object and then bind it to the DOM node, as your object "can't have" metadata you will need another object that holds metadata in a way that the property name maps to the metadata object's properties. The code will be something like this:

var a = {
        b: 'foo',
        c: 'bar'
    },
    d = {
        e: 'baz'
    },
    metadata = {
        b: 'b',
        c: 'c',
        e: 'e'
    };
function toDOM(changes){
    //changes is an array of objects changed and what happened
    //for now i'd recommend a polyfill as this syntax is still a proposal
    changes.forEach(function(change){
        var element = document.getElementById(metadata[change.name]);
        element.value = change.object[change.name];
    });
}
//Side note: you can also use currying to fix the second argument of the function (the toDOM method)
Object.observe(a, toDOM);
Object.observe(d, toDOM);

I hope that i was of help.

User.hasMany(Post, {foreignKey: 'user_id'})
Post.belongsTo(User, {foreignKey: 'user_id'})

Post.find({ where: { ...}, include: [User]})

Which will give you

SELECT
  `posts`.*,
  `users`.`username` AS `users.username`, `users`.`email` AS `users.email`,
  `users`.`password` AS `users.password`, `users`.`sex` AS `users.sex`,
  `users`.`day_birth` AS `users.day_birth`,
  `users`.`month_birth` AS `users.month_birth`,
  `users`.`year_birth` AS `users.year_birth`, `users`.`id` AS `users.id`,
  `users`.`createdAt` AS `users.createdAt`,
  `users`.`updatedAt` AS `users.updatedAt`
FROM `posts`
  LEFT OUTER JOIN `users` AS `users` ON `users`.`id` = `posts`.`user_id`;

The query above might look a bit complicated compared to what you posted, but what it does is basically just aliasing all columns of the users table to make sure they are placed into the correct model when returned and not mixed up with the posts model

Other than that you'll notice that it does a JOIN instead of selecting from two tables, but the result should be the same

Answer provided by @jAndy should work but in Firefox you may face problem, window.location.reload(1); might not work, that's my personal experience.

So i would like to suggest:

setTimeout(function() { window.location=window.location;},5000);

This is tested and works fine.

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

It's possible to get this done using seaborn.lineplot() but it involves some additional work of converting numpy arrays to pandas dataframe. Here's a complete example:

# imports
import seaborn as sns
import numpy as np
import pandas as pd

# inputs
In [41]: num = np.array([1, 2, 3, 4, 5])
In [42]: sqr = np.array([1, 4, 9, 16, 25])

# convert to pandas dataframe
In [43]: d = {'num': num, 'sqr': sqr}
In [44]: pdnumsqr = pd.DataFrame(d)

# plot using lineplot
In [45]: sns.set(style='darkgrid')
In [46]: sns.lineplot(x='num', y='sqr', data=pdnumsqr)
Out[46]: <matplotlib.axes._subplots.AxesSubplot at 0x7f583c05d0b8>

And we get the following plot:

(As of 2018, I would advise trying out JupyterHub/JupyterLab. It uses the full width of the monitor. If this is not an option, maybe since you are using one of the cloud-based Jupyter-as-a-service providers, keep reading)

(Stylish is accused of stealing user data, I have moved on to using Stylus plugin instead)

I recommend using Stylish Browser Plugin. This way you can override css for all notebooks, without adding any code to notebooks. We don't like to change configuration in .ipython/profile_default, since we are running a shared Jupyter server for the whole team and width is a user preference.

I made a style specifically for vertically-oriented high-res screens, that makes cells wider and adds a bit of empty-space in the bottom, so you can position the last cell in the centre of the screen. https://userstyles.org/styles/131230/jupyter-wide You can, of course, modify my css to your liking, if you have a different layout, or you don't want extra empty-space in the end.

Last but not least, Stylish is a great tool to have in your toolset, since you can easily customise other sites/tools to your liking (e.g. Jira, Podio, Slack, etc.)

@media (min-width: 1140px) {
  .container {
    width: 1130px;
  }
}

.end_space {
  height: 800px;
}

Well /etc/crontab just an ascii file so the simplest is to just

 echo "*/15 * * * *   root     date" >> /etc/crontab

which will add a job which will email you every 15 mins. Adjust to taste, and test via grep or other means whether the line was already added to make your script idempotent.

On Ubuntu et al, you can also drop files in /etc/cron.* which is easier to do and test for---plus you don't mess with (system) config files such as /etc/crontab.

What's missing from all the explanations is the fact that Java has a strict rule of class name = file name. Meaning if you have a class "Person", is must be in a file named "Person.java". Therefore, if one class tries to access "Person" the filename is not necessary, because it has got to be "Person.java".

Coming for C/C++, I have exact same issue. The answer is to create a new class (in a new file matching class name) and create a public string. This will be your "header" file. Then use that in your main file by using "extends" keyword.

Here is your answer:

1. Create a file called Include.java. In this file, add this:

   public class Include {
       public static String MyLongString= "abcdef";
   }
   

2. Create another file, say, User.java. In this file, put:

   import java.io.*;
   
   public class User extends Include {
       System.out.println(Include.MyLongString);
   }
   

Much simpler:

position: relative; 
left: 50%;
transform: translateX(-50%);

You are now centered in your parent element. You can do that vertically too.

It's even possible to restore without creating a blank database at all.

In Sql Server Management Studio, right click on Databases and select Restore Database...

In the Restore Database dialog, select the Source Database or Device as normal. Once the source database is selected, SSMS will populate the destination database name based on the original name of the database.

It's then possible to change the name of the database and enter a new destination database name.

With this approach, you don't even need to go to the Options tab and click the "Overwrite the existing database" option.

Also, the database files will be named consistently with your new database name and you still have the option to change file names if you want.

Based on mkozicki answer I come up with a bit different solution. I still use ActionNameSelectorAttribute But I needed to handle two buttons 'Save' and 'Sync'. They do almost the same so I didn't want to have two actions.

attribute:

public class MultipleButtonActionAttribute : ActionNameSelectorAttribute
{        
    private readonly List<string> AcceptedButtonNames;

    public MultipleButtonActionAttribute(params string[] acceptedButtonNames)
    {
        AcceptedButtonNames = acceptedButtonNames.ToList();
    }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {            
        foreach (var acceptedButtonName in AcceptedButtonNames)
        {
            var button = controllerContext.Controller.ValueProvider.GetValue(acceptedButtonName);
            if (button == null)
            {
                continue;
            }                
            controllerContext.Controller.ControllerContext.RouteData.Values.Add("ButtonName", acceptedButtonName);
            return true;
        }
        return false;
    }
}

view

<input type="submit" value="Save" name="Save" />
<input type="submit" value="Save and Sync" name="Sync" />

controller

 [MultipleButtonAction("Save", "Sync")]
 public ActionResult Sync(OrgSynchronizationEditModel model)
 {
     var btn = this.RouteData.Values["ButtonName"];

I also want to point out that if actions do different things I would probably follow mkozicki post.

For adding margins to specified cells, you can use this custom flow layout. https://github.com/voyages-sncf-technologies/VSCollectionViewCellInsetFlowLayout/

extension ViewController : VSCollectionViewDelegateCellInsetFlowLayout 
{
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForItemAt indexPath: IndexPath) -> UIEdgeInsets {
        if indexPath.item == 0 {
            return UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
        }
        return UIEdgeInsets.zero
    }
}

Also check for any long running processes executed from your .NET app against the DB. For example you may be calling a stored procedure or query which does not have enough time to finish which can show in your logs as:

• Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

  • This SqlTransaction has completed; it is no longer usable.

Check the command timeout settings Try to run a trace (profiler) and see what is happening on the DB side...

Note: This answer is for the specific question asked above. If you are here from Google and just looking for a way to get a Cartesian product in Python, itertools.product or a simple list comprehension may be what you are looking for - see the other answers.

Suppose len(list1) >= len(list2). Then what you appear to want is to take all permutations of length len(list2) from list1 and match them with items from list2. In python:

import itertools
list1=['a','b','c']
list2=[1,2]

[list(zip(x,list2)) for x in itertools.permutations(list1,len(list2))]

Returns

[[('a', 1), ('b', 2)], [('a', 1), ('c', 2)], [('b', 1), ('a', 2)], [('b', 1), ('c', 2)], [('c', 1), ('a', 2)], [('c', 1), ('b', 2)]]

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

Here's a nice and simple cache helper class/service I use:

using System.Runtime.Caching;  

public class InMemoryCache: ICacheService
{
    public T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class
    {
        T item = MemoryCache.Default.Get(cacheKey) as T;
        if (item == null)
        {
            item = getItemCallback();
            MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(10));
        }
        return item;
    }
}

interface ICacheService
{
    T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class;
}

Usage:

cacheProvider.GetOrSet("cache key", (delegate method if cache is empty));

Cache provider will check if there's anything by the name of "cache id" in the cache, and if there's not, it will call a delegate method to fetch data and store it in cache.

Example:

var products=cacheService.GetOrSet("catalog.products", ()=>productRepository.GetAll())

Another option is instanceof:

Object o =...
if (o instanceof Number) {
  double d = ((Number)o).doubleValue(); //this cast is safe
}

I usually don't have any JAVA_HOME environment variable. Java can set it up itself. Inside java java.home system property should be available.

To achieve similar functionality you could use anonymous inner classes.

If you were to define a interface Foo:

interface Foo {
    Object myFunc(Object arg);
}

Create a method bar which will receive a 'function pointer' as an argument:

public void bar(Foo foo) {
    // .....
    Object object = foo.myFunc(argValue);
    // .....
}

Finally call the method as follows:

bar(new Foo() {
    public Object myFunc(Object arg) {
        // Function code.
    }
}

One way is by using document.getElementByID, as below -

<body>
  <h1>Adding 'a' and 'b'</h1>

  a: <input type="number" name="a" id="a"><br> b: <input type="number" name="b" id="b"><br>
  <button onclick="add(document.getElementById('a').value,document.getElementById('b').value)">Add</button>

  <script>
    function add(a, b) {
      var sum = parseInt(a, 10) + parseInt(b, 10);
      alert(sum);
    }
  </script>
</body>

<?php
$file = fopen("members.txt", "r");
$members = array();

while (!feof($file)) {
   $members[] = fgets($file);
}

fclose($file);

var_dump($members);
?>

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

It's according to spec.

12.5 The if Statement 
.....

2. If ToBoolean(GetValue(exprRef)) is true, then 
a. Return the result of evaluating the first Statement. 
3. Else, 
....

ToBoolean, according to the spec, is

The abstract operation ToBoolean converts its argument to a value of type Boolean according to Table 11:

And that table says this about strings:

The result is false if the argument is the empty String (its length is zero); otherwise the result is true

Now, to explain why "0" == false you should read the equality operator, which states it gets its value from the abstract operation GetValue(lref) matches the same for the right-side.

Which describes this relevant part as:

if IsPropertyReference(V), then 
a. If HasPrimitiveBase(V) is false, then let get be the [[Get]] internal method of base, otherwise let get
be the special [[Get]] internal method defined below. 
b. Return the result of calling the get internal method using base as its this value, and passing 
GetReferencedName(V) for the argument

Or in other words, a string has a primitive base, which calls back the internal get method and ends up looking false.

If you want to evaluate things using the GetValue operation use ==, if you want to evaluate using the ToBoolean, use === (also known as the "strict" equality operator)

For me save_queries option was turned off so,

$this->db->save_queries = TRUE; //Turn ON save_queries for temporary use.
$str = $this->db->last_query();
echo $str;

That looks like docker/docker/issues/12738, seen with docker 1.6 or 1.7:

Some container fail to stop properly, and the restart

We are seeing this issue a lot in our users hosts when they upgraded from 1.5.0 to 1.6.0.
After the upgrade, some containers cannot be stopped (giving 500 Server Error: Internal Server Error ("Cannot stop container xxxxx: [2] Container does not exist: container destroyed")) or forced destroyed (giving 500 Server Error: Internal Server Error ("Could not kill running container, cannot remove - [2] Container does not exist: container destroyed")). The processes are still running on the host.
Sometimes, it works after restarting the docker daemon.

There are some workarounds:

I've tried all remote API calls for that unkillable container and here are results:

• stop, pause, wait, kill reported 404 (!)

After I finished with remote API, I double-checked docker ps (the container was still there), but then I retried docker kill and it worked! The container got killed and I could remove it.

Or:

What worked was to restart boot2docker on my host. Then docker rm -f

$ boot2docker stop
$ boot2docker start
$ docker rm -f 1f061139ba04

System.out.println("wassup"); refers to when you have to output a certain result pertaining to the proper input given by the user whereas System.err.println("duh, that's wrong); is a reference to show that the input provided is wrong or there is some other error.

Most of the IDEs show this in red color (System.err.print).

Thought I'd simplify the simplest examples copied from above, working for me on Py3.6. Simplest is multiprocessing.Pool:

import multiprocessing
import time

def worker(x):
    time.sleep(1)
    return x

pool = multiprocessing.Pool()
print(pool.map(worker, range(10)))

You can set the number of processes in the pool with, e.g., Pool(processes=5). However it defaults to CPU count, so leave it blank for CPU-bound tasks. (I/O-bound tasks often suit threads anyway, as the threads are mostly waiting so can share a CPU core.) Pool also applies chunking optimization.

(Note that the worker method cannot be nested within a method. I initially defined my worker method inside the method that makes the call to pool.map, to keep it all self-contained, but then the processes couldn't import it, and threw "AttributeError: Can't pickle local object outer_method..inner_method". More here. It can be inside a class.)

(Appreciate the original question specified printing 'represent!' rather than time.sleep(), but without it I thought some code was running concurrently when it wasn't.)

Py3's ProcessPoolExecutor is also two lines (.map returns a generator so you need the list()):

from concurrent.futures import ProcessPoolExecutor
with ProcessPoolExecutor() as executor:
    print(list(executor.map(worker, range(10))))

With plain Processes:

import multiprocessing
import time

def worker(x, queue):
    time.sleep(1)
    queue.put(x)

queue = multiprocessing.SimpleQueue()
tasks = range(10)

for task in tasks:
    multiprocessing.Process(target=worker, args=(task, queue,)).start()

for _ in tasks:
    print(queue.get())

Use SimpleQueue if all you need is put and get. The first loop starts all the processes, before the second makes the blocking queue.get calls. I don't think there's any reason to call p.join() too.

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

After hours of searching and looking for answer, finally I made it!!!!! Code is below :))))

HTML:

<form id="fileinfo" enctype="multipart/form-data" method="post" name="fileinfo">
    <label>File to stash:</label>
    <input type="file" name="file" required />
</form>
<input type="button" value="Stash the file!"></input>
<div id="output"></div>

jQuery:

$(function(){
    $('#uploadBTN').on('click', function(){ 
        var fd = new FormData($("#fileinfo"));
        //fd.append("CustomField", "This is some extra data");
        $.ajax({
            url: 'upload.php',  
            type: 'POST',
            data: fd,
            success:function(data){
                $('#output').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
});

In the upload.php file you can access the data passed with $_FILES['file'].

Thanks everyone for trying to help:)

I took the answer from here (with some changes) MDN

We should remove notification also.

Ex.

deinit 
{
  NotificationCenter.default.removeObserver(self, name:NSNotification.Name(rawValue: "notify"), object: nil)

}

Appears to be resolved by Android Studio 3.0 Canary 4 and Gradle 3.0.0-alpha4.

3 approaches for creating a fullscreen iframe:

• Approach 1 - Viewport-percentage lengths

  In supported browsers, you can use viewport-percentage lengths such as height: 100vh.

  Where 100vh represents the height of the viewport, and likewise 100vw represents the width.

  Example Here

  _x000D_

  _x000D_

  body {_x000D_
      margin: 0;            /* Reset default margin */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      height: 100vh;        /* Viewport-relative units */_x000D_
      width: 100vw;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 2 - Fixed positioning

  This approach is fairly straight-forward. Just set the positioning of the fixed element and add a height/width of 100%.

  Example Here

  _x000D_

  _x000D_

  iframe {_x000D_
      position: fixed;_x000D_
      background: #000;_x000D_
      border: none;_x000D_
      top: 0; right: 0;_x000D_
      bottom: 0; left: 0;_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 3

  For this last method, just set the height of the body/html/iframe elements to 100%.

  Example Here

  _x000D_

  _x000D_

  html, body {_x000D_
      height: 100%;_x000D_
      margin: 0;         /* Reset default margin on the body element */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

You can specify the row index in the read_csv or read_html constructors via the header parameter which represents Row number(s) to use as the column names, and the start of the data. This has the advantage of automatically dropping all the preceding rows which supposedly are junk.

import pandas as pd
from io import StringIO

In[1]
    csv = '''junk1, junk2, junk3, junk4, junk5
    junk1, junk2, junk3, junk4, junk5
    pears, apples, lemons, plums, other
    40, 50, 61, 72, 85
    '''

    df = pd.read_csv(StringIO(csv), header=2)
    print(df)

Out[1]
       pears   apples   lemons   plums   other
    0     40       50       61      72      85

The for loop runs immediately to completion while all your asynchronous operations are started. When they complete some time in the future and call their callbacks, the value of your loop index variable i will be at its last value for all the callbacks.

This is because the for loop does not wait for an asynchronous operation to complete before continuing on to the next iteration of the loop and because the async callbacks are called some time in the future. Thus, the loop completes its iterations and THEN the callbacks get called when those async operations finish. As such, the loop index is "done" and sitting at its final value for all the callbacks.

To work around this, you have to uniquely save the loop index separately for each callback. In Javascript, the way to do that is to capture it in a function closure. That can either be done be creating an inline function closure specifically for this purpose (first example shown below) or you can create an external function that you pass the index to and let it maintain the index uniquely for you (second example shown below).

As of 2016, if you have a fully up-to-spec ES6 implementation of Javascript, you can also use let to define the for loop variable and it will be uniquely defined for each iteration of the for loop (third implementation below). But, note this is a late implementation feature in ES6 implementations so you have to make sure your execution environment supports that option.

Use .forEach() to iterate since it creates its own function closure

someArray.forEach(function(item, i) {
    asynchronousProcess(function(item) {
        console.log(i);
    });
});

Create Your Own Function Closure Using an IIFE

var j = 10;
for (var i = 0; i < j; i++) {
    (function(cntr) {
        // here the value of i was passed into as the argument cntr
        // and will be captured in this function closure so each
        // iteration of the loop can have it's own value
        asynchronousProcess(function() {
            console.log(cntr);
        });
    })(i);
}

Create or Modify External Function and Pass it the Variable

If you can modify the asynchronousProcess() function, then you could just pass the value in there and have the asynchronousProcess() function the cntr back to the callback like this:

var j = 10;
for (var i = 0; i < j; i++) {
    asynchronousProcess(i, function(cntr) {
        console.log(cntr);
    });
}

Use ES6 let

If you have a Javascript execution environment that fully supports ES6, you can use let in your for loop like this:

const j = 10;
for (let i = 0; i < j; i++) {
    asynchronousProcess(function() {
        console.log(i);
    });
}

let declared in a for loop declaration like this will create a unique value of i for each invocation of the loop (which is what you want).

Serializing with promises and async/await

If your async function returns a promise, and you want to serialize your async operations to run one after another instead of in parallel and you're running in a modern environment that supports async and await, then you have more options.

async function someFunction() {
    const j = 10;
    for (let i = 0; i < j; i++) {
        // wait for the promise to resolve before advancing the for loop
        await asynchronousProcess();
        console.log(i);
    }
}

This will make sure that only one call to asynchronousProcess() is in flight at a time and the for loop won't even advance until each one is done. This is different than the previous schemes that all ran your asynchronous operations in parallel so it depends entirely upon which design you want. Note: await works with a promise so your function has to return a promise that is resolved/rejected when the asynchronous operation is complete. Also, note that in order to use await, the containing function must be declared async.

Run asynchronous operations in parallel and use Promise.all() to collect results in order

 function someFunction() {
     let promises = [];
     for (let i = 0; i < 10; i++) {
          promises.push(asynchonousProcessThatReturnsPromise());
     }
     return Promise.all(promises);
 }

 someFunction().then(results => {
     // array of results in order here
     console.log(results);
 }).catch(err => {
     console.log(err);
 });

Add this to the end of your proc: option(recompile)

This will make the report run almost as fast as the stored procedure

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

I had this problem, it is for foreign-key

Click on the Relation View (like the image below) then find name of the field you are going to remove it, and under the Foreign key constraint (INNODB) column, just put the select to nothing! Means no foreign-key

Hope that works!

To use mvn deploy:deploy-file, must add ~./m2/settings.xml

<settings>
  <servers>
    <server>
      <id>nexus-repo</id>
      <username>admin</username>
      <password>admin123</password>

</settings>

command:

mvn deploy:deploy-file -DgroupId=com.example \
                                       -DartifactId=my-app \

                                       -DgeneratePom=true \
                                       -DrepositoryId=nexus-repo \

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

I got this when I renamed a project. Although the project is renamed, some references are not. Clearing lint, and then rerunning lint helped. (Right click project > Android Tools > Clear Lint Markers, then Run Lint)

You can also do it this way, allowing polymorphism:

class Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Base: " << b << "; ";
   }
private:
  int b;
};

class Derived : public Base {
public:
   virtual std::ostream& dump(std::ostream& o) const {
      return o << "Derived: " << d << "; ";
   }
private:
   int d;
}

std::ostream& operator<<(std::ostream& o, const Base& b) { return b.dump(o); }

As Martin K suggested java.util.concurrent.CountDownLatch seems to be a better solution for this. Just adding an example for the same

     public class CountDownLatchDemo
{

    public static void main (String[] args)
    {
        int noOfThreads = 5;
        // Declare the count down latch based on the number of threads you need
        // to wait on
        final CountDownLatch executionCompleted = new CountDownLatch(noOfThreads);
        for (int i = 0; i < noOfThreads; i++)
        {
            new Thread()
            {

                @Override
                public void run ()
                {

                    System.out.println("I am executed by :" + Thread.currentThread().getName());
                    try
                    {
                        // Dummy sleep
                        Thread.sleep(3000);
                        // One thread has completed its job
                        executionCompleted.countDown();
                    }
                    catch (InterruptedException e)
                    {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }

            }.start();
        }

        try
        {
            // Wait till the count down latch opens.In the given case till five
            // times countDown method is invoked
            executionCompleted.await();
            System.out.println("All over");
        }
        catch (InterruptedException e)
        {
            e.printStackTrace();
        }
    }

}

I know I am quite late, but I just wanted to add a few things to the already correct answer provided by @Grijesh. I'd like to just point out that the answer provided by @Grijesh does not produce the minimal DFA. While the answer surely is the right way to get a DFA, if you need the minimal DFA you will have to look into your divisor.

Like for example in binary numbers, if the divisor is a power of 2 (i.e. 2^n) then the minimum number of states required will be n+1. How would you design such an automaton? Just see the properties of binary numbers. For a number, say 8 (which is 2^3), all its multiples will have the last 3 bits as 0. For example, 40 in binary is 101000. Therefore for a language to accept any number divisible by 8 we just need an automaton which sees if the last 3 bits are 0, which we can do in just 4 states instead of 8 states. That's half the complexity of the machine.

In fact, this can be extended to any base. For a ternary base number system, if for example we need to design an automaton for divisibility with 9, we just need to see if the last 2 numbers of the input are 0. Which can again be done in just 3 states.

Although if the divisor isn't so special, then we need to go through with @Grijesh's answer only. Like for example, in a binary system if we take the divisors of 3 or 7 or maybe 21, we will need to have that many number of states only. So for any odd number n in a binary system, we need n states to define the language which accepts all multiples of n. On the other hand, if the number is even but not a power of 2 (only in case of binary numbers) then we need to divide the number by 2 till we get an odd number and then we can find the minimum number of states by adding the odd number produced and the number of times we divided by 2.

For example, if we need to find the minimum number of states of a DFA which accepts all binary numbers divisible by 20, we do :

20/2 = 10 
10/2 = 5

Hence our answer is 5 + 1 + 1 = 7. (The 1 + 1 because we divided the number 20 twice).

To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.

In addition to excellent answers already provided, there are some cases where explicit implementation is REQUIRED for the compiler to be able to figure out what is required. Take a look at IEnumerable<T> as a prime example that will likely come up fairly often.

Here's an example:

public abstract class StringList : IEnumerable<string>
{
    private string[] _list = new string[] {"foo", "bar", "baz"};

    // ...

    #region IEnumerable<string> Members
    public IEnumerator<string> GetEnumerator()
    {
        foreach (string s in _list)
        { yield return s; }
    }
    #endregion

    #region IEnumerable Members
    IEnumerator IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }
    #endregion
}

Here, IEnumerable<string> implements IEnumerable, hence we need to too. But hang on, both the generic and the normal version both implement functions with the same method signature (C# ignores return type for this). This is completely legal and fine. How does the compiler resolve which to use? It forces you to only have, at most, one implicit definition, then it can resolve whatever it needs to.

ie.

StringList sl = new StringList();

// uses the implicit definition.
IEnumerator<string> enumerableString = sl.GetEnumerator();
// same as above, only a little more explicit.
IEnumerator<string> enumerableString2 = ((IEnumerable<string>)sl).GetEnumerator();
// returns the same as above, but via the explicit definition
IEnumerator enumerableStuff = ((IEnumerable)sl).GetEnumerator();

PS: The little piece of indirection in the explicit definition for IEnumerable works because inside the function the compiler knows that the actual type of the variable is a StringList, and that's how it resolves the function call. Nifty little fact for implementing some of the layers of abstraction some of the .NET core interfaces seem to have accumulated.

The Eclipse UI is a little bit confusing.

The Import -> "Existing projects into workspace" actually means import "Existing Eclipse projects into workspace". That's why you can't click on finish: the import option looks for a .project file (the file used by Eclipse to store the project options) in the directory that you have chosen.

To import existing source code that doesn't have an Eclipse project file you have the following options (I suppose that you want to create a Java project):

1. New project inside the workspace dir: Create a new empty Java project into the workspace (File->New->Java Project). Then right click on the source folder and choose Import...->General->File system then choose your files, and it will make a copy of your files.

   Tip: you can drag&drop your files from the Finder into the src folder.

2. Create an eclipse project in your existing dir: Create a new Java project, but in the "New Java Project" window:

   • Un check the Use default location option, and choose the directory where is your non-Eclipse project.
   • Click Next and configure the sub-directories of your non-Eclipse project where the source files are located. And you are done :)
