If you're deleting multiple non-adjacent items, then what you describe is the best way (and yes, be sure to start from the highest index).

If your items are adjacent, you can use the slice assignment syntax:

a[2:10] = []

You should change your code to make use of SqlParameters and adapt your insert statement to the following

string connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// [ ] required as your fields contain spaces!!
string insStmt = "insert into Main ([First Name], [Last Name]) values (@firstName,@lastName)";

using (SqlConnection cnn = new SqlConnection(connetionString))
{
    cnn.Open();
    SqlCommand insCmd = new SqlCommand(insStmt, cnn);
    // use sqlParameters to prevent sql injection!
    insCmd.Parameters.AddWithValue("@firstName", textbox2.Text);
    insCmd.Parameters.AddWithValue("@lastName", textbox3.Text);
    int affectedRows = insCmd.ExecuteNonQuery();
    MessageBox.Show (affectedRows + " rows inserted!");
}

You can have it in the xml.

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        app:tabTextColor="@color/colorGray"
        app:tabSelectedTextColor="@color/colorWhite"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

We can pass string value to main method as argument without using commandline argument concept in java through Netbean

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

Output

Enter any string :

To force users to enable JavaScripts, I set 'href' attribute of each link to the same document, which notifies user to enable JavaScripts or download Firefox (if they don't know how to enable JavaScripts). I stored actual link url to the 'name' attribute of links and defined a global onclick event that reads 'name' attribute and redirects the page there.

This works well for my user-base, though a bit fascist ;).

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

I had the same problem. One day the program was working perfectly, and the following wasn't. I checked on Github the changes I made. For me the problem was on build.gradle (Module:app) in the dependencies:

compile 'com.android.tools.build:gradle:2.1.2'

This line was the one that was causing the problem. After changing it the app was running properly again

If you don't want the image to affect the layout at all (and float on top of other content) you can apply the following CSS to the image:

position:absolute;
right:0;
top:0;

If you want it to float at the right of a particular parent section, you can add position: relative to that section.

HashMap is an array of Entry objects.

Consider HashMap as just an array of objects.

Have a look at what this Object is:

static class Entry<K,V> implements Map.Entry<K,V> {
        final K key;
        V value;
        Entry<K,V> next;
        final int hash;
… 
}

Each Entry object represents a key-value pair. The field next refers to another Entry object if a bucket has more than one Entry.

Sometimes it might happen that hash codes for 2 different objects are the same. In this case, two objects will be saved in one bucket and will be presented as a linked list. The entry point is the more recently added object. This object refers to another object with the next field and so on. The last entry refers to null.

When you create a HashMap with the default constructor

HashMap hashMap = new HashMap();

The array is created with size 16 and default 0.75 load balance.

Adding a new key-value pair

1. Calculate hashcode for the key
2. Calculate position hash % (arrayLength-1) where element should be placed (bucket number)
3. If you try to add a value with a key which has already been saved in HashMap, then value gets overwritten.
4. Otherwise element is added to the bucket.

If the bucket already has at least one element, a new one gets added and placed in the first position of the bucket. Its next field refers to the old element.

Deletion

1. Calculate hashcode for the given key
2. Calculate bucket number hash % (arrayLength-1)
3. Get a reference to the first Entry object in the bucket and by means of equals method iterate over all entries in the given bucket. Eventually we will find the correct Entry. If a desired element is not found, return null

Note that if the problem is being caused by appearing scrollbars, putting

body {
  overflow: hidden;
}

in your CSS might be an easy fix (if you don't need the page to scroll).

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

Using the provided IntentInegrator is better. It allows you to prompt your user to install the barcode scanner if they do not have it. It also allows you to customize the messages. The IntentIntegrator.REQUEST_CODE constant holds the value of the request code for the onActivityResult to check for in the above if block.

IntentIntegrator intentIntegrator = new IntentIntegrator(this); // where this is activity 
intentIntegrator.initiateScan(IntentIntegrator.ALL_CODE_TYPES); // or QR_CODE_TYPES if you need to scan QR

IntentIntegrator.java

You are close already. Just make sure to hide the checkbox and associate it with a label you style via input[checkbox] + label

Maybe it's an entirely different situation, but I always got WebView[43046:188825] Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service when opening a webpage on the simulator while having the debugger attached to it. If I end the debugger and opening the app again the webpage will open just fine. This doesn't happen on the devices.

After spending an entire work-day trying to figure out what's wrong, I found out that if we have a framework named Preferences, UIWebView and WKWebView will not be able to open a webpage and will throw the error above.

To reproduce this error just make a simple app with WKWebView to show a webpage. Then create a new framework target and name it Preferences. Then import it to the main target and run the simulator again. WKWebView will fail to open a webpage.

So, it might be unlikely, but if you have a framework with the name Preferences, try deleting or renaming it.

Also, if anyone has an explanation for this please do share.

BTW, I was on Xcode 9.2.

You can do it with initializer list:

std::vector<unsigned int> array;

// First argument is an iterator to the element BEFORE which you will insert:
// In this case, you will insert before the end() iterator, which means appending value
// at the end of the vector.
array.insert(array.end(), { 1, 2, 3, 4, 5, 6 });

The easy way is by using sprintf. I know others have suggested itoa, but a) it isn't part of the standard library, and b) sprintf gives you formatting options that itoa doesn't.

BUFFER_SIZE is the size of chucks to read in. Should be > 1kb and < 10MB.

private static final int BUFFER_SIZE = 2 * 1024 * 1024;
private void copy(InputStream input, OutputStream output) throws IOException {
    try {
        byte[] buffer = new byte[BUFFER_SIZE];
        int bytesRead = input.read(buffer);
        while (bytesRead != -1) {
            output.write(buffer, 0, bytesRead);
            bytesRead = input.read(buffer);
        }
    //If needed, close streams.
    } finally {
        input.close();
        output.close();
    }
}

Add .* to s in your first line.

Try:

DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");

When working with a list (direct indexing), you cannot do it as efficiently as using a for loop.

Edit: Which generally means, when you are able to use a for loop, it's likely the correct method for this task. Plus, for as much as foreach is implemented in-order, the construct itself is built for expressing loops that are independent of element indexes and iteration order, which is particularly important in parallel programming. It is my opinion that iteration relying on order should not use foreach for looping.

There are several other ways, besides using the in operator (easiest):

index()

>>> try:
...   "xxxxABCDyyyy".index("test")
... except ValueError:
...   print "not found"
... else:
...   print "found"
...
not found

find()

>>> if "xxxxABCDyyyy".find("ABCD") != -1:
...   print "found"
...
found

re

>>> import re
>>> if re.search("ABCD" , "xxxxABCDyyyy"):
...  print "found"
...
found

It should be:

ClientThread hey = clients.get(clients.size() - 1);
clients.remove(hey);

Or you can do

clients.remove(clients.size() - 1);

The minus ones are because size() returns the number of elements, but the ArrayList's first element's index is 0 and not 1.

Please note: The first part of this answer is or version 1.x of pendulum. See below for a version 2.x answer.

I hope I'm not too late!

The pendulum library excels at this and other date-time calculations.

>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.datetime.strptime(heres_a_time, '%Y-%m-%d %H:%M %z')
>>> for tz in some_time_zones:
...     tz, pendulum_time.astimezone(tz)
...     
('Europe/Paris', <Pendulum [1996-03-25T17:03:00+01:00]>)
('Europe/Moscow', <Pendulum [1996-03-25T19:03:00+03:00]>)
('America/Toronto', <Pendulum [1996-03-25T11:03:00-05:00]>)
('UTC', <Pendulum [1996-03-25T16:03:00+00:00]>)
('Canada/Pacific', <Pendulum [1996-03-25T08:03:00-08:00]>)
('Asia/Macao', <Pendulum [1996-03-26T00:03:00+08:00]>)

Answer lists the names of the time zones that may be used with pendulum. (They're the same as for pytz.)

For version 2:

• some_time_zones is a list of the names of the time zones that might be used in a program
• heres_a_time is a sample time, complete with a time zone in the form '-0400'
• I begin by converting the time to a pendulum time for subsequent processing
• now I can show what this time is in each of the time zones in show_time_zones

...

>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.from_format('1996-03-25 12:03 -0400', 'YYYY-MM-DD hh:mm ZZ')
>>> for tz in some_time_zones:
...     tz, pendulum_time.in_tz(tz)
...     
('Europe/Paris', DateTime(1996, 3, 25, 17, 3, 0, tzinfo=Timezone('Europe/Paris')))
('Europe/Moscow', DateTime(1996, 3, 25, 19, 3, 0, tzinfo=Timezone('Europe/Moscow')))
('America/Toronto', DateTime(1996, 3, 25, 11, 3, 0, tzinfo=Timezone('America/Toronto')))
('UTC', DateTime(1996, 3, 25, 16, 3, 0, tzinfo=Timezone('UTC')))
('Canada/Pacific', DateTime(1996, 3, 25, 8, 3, 0, tzinfo=Timezone('Canada/Pacific')))
('Asia/Macao', DateTime(1996, 3, 26, 0, 3, 0, tzinfo=Timezone('Asia/Macao')))

As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:

private _entityId: number;

constructor(private _route: ActivatedRoute) {
    // ...
}

ngOnInit() {
    // For a static snapshot of the route...
    this._entityId = this._route.snapshot.paramMap.get('id');

    // For subscribing to the observable paramMap...
    this._route.paramMap.pipe(
        switchMap((params: ParamMap) => this._entityId = params.get('id'))
    );

    // Or as an alternative, with slightly different execution...
    this._route.paramMap.subscribe((params: ParamMap) =>  {
        this._entityId = params.get('id');
    });
}

I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.

Use ast.literal_eval to evaluate Python literals. However, what you have is JSON (note "true" for example), so use a JSON deserializer.

>>> import json
>>> s = """{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/www.facebook.com\/jdoe","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}"""
>>> json.loads(s)
{u'first_name': u'John', u'last_name': u'Doe', u'verified': True, u'name': u'John Doe', u'locale': u'en_US', u'gender': u'male', u'email': u'[email protected]', u'link': u'http://www.facebook.com/jdoe', u'timezone': -7, u'updated_time': u'2011-01-12T02:43:35+0000', u'id': u'123456789'}

A non-jquery version that works in both webkit and gecko:

var keyboardEvent = document.createEvent('KeyboardEvent');
var initMethod = typeof keyboardEvent.initKeyboardEvent !== 'undefined' ? 'initKeyboardEvent' : 'initKeyEvent';

keyboardEvent[initMethod](
  'keydown', // event type: keydown, keyup, keypress
  true, // bubbles
  true, // cancelable
  window, // view: should be window
  false, // ctrlKey
  false, // altKey
  false, // shiftKey
  false, // metaKey
  40, // keyCode: unsigned long - the virtual key code, else 0
  0, // charCode: unsigned long - the Unicode character associated with the depressed key, else 0
);
document.dispatchEvent(keyboardEvent);

Simple solution to resolve this problem is to set an empty value by default :

<input name='myInput' value={this.state.myInput || ''} onChange={this.handleChange} />

RegExp is universal, but I understand that you're working with arrays. So, check out this approach. I use to use it, and it's very effective and blazing fast!

var str = 'some string with a';
var list = ['a', 'b', 'c'];
var rx = new RegExp(list.join('|'));

rx.test(str);

You can also apply some modifications, i.e.:

One-liner

new RegExp(list.join('|')).test(str);

Case insensitive

var rx = new RegExp(list.join('|').concat('/i'));

And many others!

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

Regret to say, but Both Otacku's and @clatonh's methods aren't working for me - neither have Outlook Bitness nor {90140000-0011-0000-1000-0000000FF1CE} in registry (for 64-bit Office without Outlook installed).

The only way I have found, though, not via the registry, is to check bitness for one of the Office executables with the use of the Windows API function GetBinaryType (since Windows 2000 Professional).

For example, you can check the bitness of Winword.exe, which path is stored under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Winword.exe.

Here is the MFC code fragment:

CRegKey rk;
if (ERROR_SUCCESS == rk.Open(HKEY_LOCAL_MACHINE, 
  "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\Winword.exe", 
  KEY_READ)) {
    CString strWinwordPath;
    DWORD dwSize = MAX_PATH;
    if (ERROR_SUCCESS == rk.QueryStringValue(strWinwordPath, 
        strWinwordPath.GetBuffer(MAX_PATH), &dwSize)) {
            strWinwordPath.ReleaseBuffer();
            DWORD dwBinaryType;
            if (::GetBinaryType(strWinwordPath, &dwBinaryType)) {
                if (SCS_64BIT_BINARY == dwBinaryType) {
                    // Detected 64-bit Office 
                } else {
                    // Detected 32-bit Office 
                }
            } else {
                // Failed
            }
        } else {
            // Failed
        }
    } else {
    // Failed
}

// initializing depending on i,j:_x000D_
var M=Array.from({length:9}, (_,i) => Array.from({length:9}, (_,j) => i+'x'+j))_x000D_
_x000D_
// Print it:_x000D_
_x000D_
console.table(M)_x000D_
// M.forEach(r => console.log(r))_x000D_
document.body.innerHTML = `<pre>${M.map(r => r.join('\t')).join('\n')}</pre>`_x000D_
// JSON.stringify(M, null, 2) // bad for matrices

Beware that doing this below, is wrong:

// var M=Array(9).fill([]) // since arrays are sparse
// or Array(9).fill(Array(9).fill(0))// initialization

// M[4][4] = 1
// M[3][4] is now 1 too!

Because it creates the same reference of Array 9 times, so modifying an item modifies also items at the same index of other rows (since it's the same reference), so you need an additional call to .slice or .map on the rows to copy them (cf torazaburo's answer which fell in this trap)

note: It may look like this in the future, with slice-notation-literal proposal (stage 1)

const M = [...1:10].map(i => [...1:10].map(j => i+'x'+j))

What you should not do do (especially when working on a shared project)

Ok, after had the same issue and after reading some answers here and other places. it seems that putting external lib into WEB-INF/lib is not that good idea as it pollute webapp/JRE libs with server-specific libraries - for more information check this answer"

Another solution that i do NOT recommend is: to copy it into tomcat/lib folder. although this may work, it will be hard to manage dependency for a shared(git for example) project.

Good solution 1

Create vendor folder. put there all your external lib. then, map this folder as dependency to your project. in eclipse you need to

1. add your folder to the build path
   1. Project Properties -> Java build path
   2. Libraries -> add external lib or any other solution to add your files/folder
2. add your build path to deployment Assembly (reference)
   1. Project Properties -> Deployment Assembly
   2. Add -> Java Build Path Entries
   3. You should now see the list of libraries on your build path that you can specify for inclusion into your finished WAR.
   4. Select the ones you want and hit Finish.

Good solution 2

Use maven (or any alternative) to manage project dependency

This might be very late answer. But this chart kills it.

You appear to be trying to mix query expression syntax and "normal" lambda expression syntax. You can either use:

IEnumerable<SelectListItem> stores =
        from store in database.Stores
        where store.CompanyID == curCompany.ID
        select new SelectListItem { Value = store.Name, Text = store.ID};
ViewBag.storeSelector = stores;

Or:

IEnumerable<SelectListItem> stores = database.Stores
        .Where(store => store.CompanyID == curCompany.ID)
        .Select(s => new SelectListItem { Value = s.Name, Text = s.ID});
ViewBag.storeSelector = stores;

You can't mix the two like you're trying to.

Since Marco's answer is deprecated, you must use the following syntax (according jasonlfunk's comment) :

$response = $client->request('POST', 'http://www.example.com/user/create', [
    'form_params' => [
        'email' => '[email protected]',
        'name' => 'Test user',
        'password' => 'testpassword',
    ]
]);

Request with POST files

$response = $client->request('POST', 'http://www.example.com/files/post', [
    'multipart' => [
        [
            'name'     => 'file_name',
            'contents' => fopen('/path/to/file', 'r')
        ],
        [
            'name'     => 'csv_header',
            'contents' => 'First Name, Last Name, Username',
            'filename' => 'csv_header.csv'
        ]
    ]
]);

REST verbs usage with params

// PUT
$client->put('http://www.example.com/user/4', [
    'body' => [
        'email' => '[email protected]',
        'name' => 'Test user',
        'password' => 'testpassword',
    ],
    'timeout' => 5
]);

// DELETE
$client->delete('http://www.example.com/user');

Async POST data

Usefull for long server operations.

$client = new \GuzzleHttp\Client();
$promise = $client->requestAsync('POST', 'http://www.example.com/user/create', [
    'form_params' => [
        'email' => '[email protected]',
        'name' => 'Test user',
        'password' => 'testpassword',
    ]
]);
$promise->then(
    function (ResponseInterface $res) {
        echo $res->getStatusCode() . "\n";
    },
    function (RequestException $e) {
        echo $e->getMessage() . "\n";
        echo $e->getRequest()->getMethod();
    }
);

Set headers

According to documentation, you can set headers :

// Set various headers on a request
$client->request('GET', '/get', [
    'headers' => [
        'User-Agent' => 'testing/1.0',
        'Accept'     => 'application/json',
        'X-Foo'      => ['Bar', 'Baz']
    ]
]);

More information for debugging

If you want more details information, you can use debug option like this :

$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://www.example.com/user/create', [
    'form_params' => [
        'email' => '[email protected]',
        'name' => 'Test user',
        'password' => 'testpassword',
    ],
    // If you want more informations during request
    'debug' => true
]);

Documentation is more explicits about new possibilities.

Identify the real process programmatically

(when the process ID is shown as 4)

The answers here, as usual, expect a level of interactivity.

The problem is when something is listening through HTTP.sys; then, the PID is always 4 and, as most people find, you need some tool to find the real owner.

Here's how to identify the offending process programmatically. No TcpView, etc (as good as those tools are). Does rely on netsh; but then, the problem is usually related to HTTP.sys.

$Uri = "http://127.0.0.1:8989"    # for example


# Shows processes that have registered URLs with HTTP.sys
$QueueText = netsh http show servicestate view=requestq verbose=yes | Out-String

# Break into text chunks; discard the header
$Queues    = $QueueText -split '(?<=\n)(?=Request queue name)' | Select-Object -Skip 1

# Find the chunk for the request queue listening on your URI
$Queue     = @($Queues) -match [regex]::Escape($Uri -replace '/$')


if ($Queue.Count -eq 1)
{
    # Will be null if could not pick out exactly one PID
    $ProcessId = [string]$Queue -replace '(?s).*Process IDs:\s+' -replace '(?s)\s.*' -as [int]

    if ($ProcessId)
    {
        Write-Verbose "Identified process $ProcessId as the HTTP listener. Killing..."
        Stop-Process -Id $ProcessId -Confirm
    }
}

May I suggest that you initialize your "max and min so far" variables not to infinity, but to the first number in the array?

Go to your mysql bin directory and install mysql service again:

c:
cd \mysql\bin
mysqld-nt.exe --install

or if mysqld-nt.exe is missing (depending on version):

mysqld.exe --install

Then go to services, start the service and set it to automatic start.

For having .html files parsed as well, you need to set the appropriate handler in your server config.

For Apache httpd 2.X this is the following line

AddHandler application/x-httpd-php .html

See the PHP docu for information on your specific server installation.

I do this with mustache.js and templates (you could use any JavaScript templating library).

In my view, I have something like this:

<script type="text/x-mustache-template" id="modalTemplate">
    <%Html.RenderPartial("Modal");%>
</script>

...which lets me keep my templates in a partial view called Modal.ascx:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
    <div>
        <div class="modal-header">
            <a class="close" data-dismiss="modal">&times;</a>
            <h3>{{Name}}</h3>
        </div>
        <div class="modal-body">
            <table class="table table-striped table-condensed">
                <tbody>
                    <tr><td>ID</td><td>{{Id}}</td></tr>
                    <tr><td>Name</td><td>{{Name}}</td></tr>
                </tbody>
            </table>
        </div>
        <div class="modal-footer">
            <a class="btn" data-dismiss="modal">Close</a>
        </div>
    </div>

I create placeholders for each modal in my view:

<%foreach (var item in Model) {%>
    <div data-id="<%=Html.Encode(item.Id)%>"
         id="modelModal<%=Html.Encode(item.Id)%>" 
         class="modal hide fade">
    </div>
<%}%>

...and make ajax calls with jQuery:

<script type="text/javascript">
    var modalTemplate = $("#modalTemplate").html()
    $(".modal[data-id]").each(function() {
        var $this = $(this)
        var id = $this.attr("data-id")
        $this.on("show", function() {
            if ($this.html()) return
            $.ajax({
                type: "POST",
                url: "<%=Url.Action("SomeAction")%>",
                data: { id: id },
                success: function(data) {
                    $this.append(Mustache.to_html(modalTemplate, data))
                }
            })
        })
    })
</script>

Then, you just need a trigger somewhere:

<%foreach (var item in Model) {%>
    <a data-toggle="modal" href="#modelModal<%=Html.Encode(item.Id)%>">
        <%=Html.Encode(item.DutModel.Name)%>
    </a>
<%}%>

**Solution which worked for me
Use NestedScrollView with height as wrap_content

<br> RecyclerView

        android:layout_height="wrap_content"

//Your row content goes here

A Java one liner

public String getCurrentTimeStamp() {
    return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(new Date());
}

in JDK8 style

public String getCurrentLocalDateTimeStamp() {
    return LocalDateTime.now()
       .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));
}

Update: ASP.NET Core does not have a SynchronizationContext. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false) or not.

For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.

Original post (for non-Core ASP.NET):

This video by the ASP.NET team has the best information on using async on ASP.NET.

I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.

This is true with UI applications, where there is only one UI thread that you have to "sync" back to.

In ASP.NET, the situation is a bit more complex. When an async method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false), then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.

So ConfigureAwait(false) does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false) could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.

Actually, just doing an await can do that. Once your async method hits an await, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.

The only difference ConfigureAwait makes in ASP.NET is whether that thread enters the request context when resuming the method.

I have more background information in my MSDN article on SynchronizationContext and my async intro blog post.

As to the short script, the following runs on my Linux host

#!/bin/bash
HOST_DIR=<pull-to>
DEVICE_DIR=/sdcard/<pull-from>
EXTENSION="\.jpg"

while read MYFILE ; do
    adb pull "$DEVICE_DIR/$MYFILE" "$HOST_DIR/$MYFILE"
done < $(adb shell ls -1 "$DEVICE_DIR" | grep "$EXTENSION")

"ls minus one" lets "ls" show one file per line, and the quotation marks allow spaces in the filename.

I had this problem after upgrading from Android Studio 2.3 to 3.0. As simple as it sounds, I actually just restarted my phone to fix it.

My guess is that the adb server on the phone somehow cached something from the previous installation of android studio, maybe a connection object or something, and by restarting the adb server it resolved the issue.

I hope this helps someone.

A nice way of doing this is to use the addObserver(forName:object:queue:using:) method rather than the addObserver(_:selector:name:object:) method that is often used from Objective-C code. The advantage of the first variant is that you don't have to use the @objc attribute on your method:

    func batteryLevelChanged(notification: Notification) {
        // do something useful with this information
    }

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil,
        using: batteryLevelChanged)

and you can even just use a closure instead of a method if you want:

    let observer = NotificationCenter.default.addObserver(
        forName: NSNotification.Name.UIDeviceBatteryLevelDidChange,
        object: nil, queue: nil) { _ in print("") }

You can use the returned value to stop listening for the notification later:

    NotificationCenter.default.removeObserver(observer)

There used to be another advantage in using this method, which was that it doesn't require you to use selector strings which couldn't be statically checked by the compiler and so were fragile to breaking if the method is renamed, but Swift 2.2 and later include #selector expressions that fix that problem.

You can get the latest version of Boost by using Homebrew.

brew install boost.

And the Scala version:

def gcd(a: Int, b: Int): Int = if (b == 0) a else gcd(b, a % b)
def gcd(nums: Iterable[Int]): Int = nums.reduce(gcd)
def lcm(a: Int, b: Int): Int = if (a == 0 || b == 0) 0 else a * b / gcd(a, b)
def lcm(nums: Iterable[Int]): Int = nums.reduce(lcm)

It has some interesting behaviour in some cases that is good to be aware of:

from werkzeug.datastructures import MultiDict

d = MultiDict([("ex1", ""), ("ex2", None)])

d.get("ex1", "alternive")
# returns: ''

d.get("ex2", "alternative")
# returns no visible output of any kind
# It is returning literally None, so if you do:
d.get("ex2", "alternative") is None
# it returns: True

d.get("ex3", "alternative")
# returns: 'alternative'

TextView txtvw = (TextView)findViewById(R.id.TextView01);
        txtvw.setText(readTxt());

 private String readTxt()
    {
    InputStream raw = getResources().openRawResource(R.raw.hello);

    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

    int i;
    try
    {
        i = raw.read();
        while (i != -1)
        {
            byteArrayOutputStream.write(i);
            i = raw.read();
        }
        raw.close();
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block

        e.printStackTrace();
    }


    return byteArrayOutputStream.toString();

}

rest is to be written in class extending Activity!!

The str.split() method without an argument splits on whitespace:

>>> "many   fancy word \nhello    \thi".split()
['many', 'fancy', 'word', 'hello', 'hi']

I just had the exact same issue and it was down to me being completely stupid. I had disabled all of the form fields (rather than just the submit button) via javascript before submitting said form! This, of course, resulted in the all the form elements not being submitted (including the hidden _token field) which in turn brought up the 419 error!

I hope this helps someone from a few hours of head scratching!

Disabled form inputs do not appear in the request

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

Don't know the nature of your app, but I have seen this error manifested multiple times because of a connection pool leak, so that would be worth checking out. On Linux, socket connections consume file descriptors as well as file system files. Just a thought.

As an alternative to Regex, running:

Sub Replacer()
   Dim N As Long, i As Long
   N = Cells(Rows.Count, "A").End(xlUp).Row

   For i = 1 To N
      If Left(Cells(i, "A").Value, 9) = "texts are" Then
         Cells(i, "A").Value = "texts are replaced"
      End If
   Next i
End Sub

will produce:

Assuming the variable is something akin to:

CREATE TYPE [dbo].[IntList] AS TABLE(
[Value] [int] NOT NULL
)

And the Stored Procedure is using it in this form:

ALTER Procedure [dbo].[GetFooByIds]
    @Ids [IntList] ReadOnly
As 

You can create the IntList and call the procedure like so:

Declare @IDs IntList;
Insert Into @IDs Select Id From dbo.{TableThatHasIds}
Where Id In (111, 222, 333, 444)
Exec [dbo].[GetFooByIds] @IDs

Or if you are providing the IntList yourself

DECLARE @listOfIDs dbo.IntList
INSERT INTO @listofIDs VALUES (1),(35),(118);

Your hostname is missing. JBoss uses this environment variable ($HOSTNAME) when it connects to the server.

[root@xyz ~]# echo $HOSTNAME
xyz

[root@xyz ~]# ping $HOSTNAME
ping: unknown host xyz

[root@xyz ~]# hostname -f
hostname: Unknown host

There are dozens of things that can cause this. Please comment if you discover a new reason.

For a hack until you can permanently resolve this issue on your server, you can add a line to the end of your /etc/hosts file:

127.0.0.1 xyz.xxx.xxx.edu xyz

It's may be a little bit late, but here is more suitable code, for example when you need to use loops:

            List<int> genered = new List<int>();

            Random rnd = new Random();

            for(int x = 0; x < files.Length; x++)
            {
                int value = rnd.Next(0, files.Length - 1);
                while (genered.Contains(value))
                {
                    value = rnd.Next(0, files.Length - 1);
                }
                genered.Add(value);

                returnFiles[x] = files[value];
            }

Just to point out the generic way to iterate over any map:

 private <K, V> void iterateOverMap(Map<K, V> map) {
    for (Map.Entry<K, V> entry : map.entrySet()) {
        System.out.println("key ->" + entry.getKey() + ", value->" + entry.getValue());
    }
    }

Method below will do all the job (memory allocation, counting the length) for you. More information and description can be found here - Implementation of Java String.split() method to split C string

int split (const char *str, char c, char ***arr)
{
    int count = 1;
    int token_len = 1;
    int i = 0;
    char *p;
    char *t;

    p = str;
    while (*p != '\0')
    {
        if (*p == c)
            count++;
        p++;
    }

    *arr = (char**) malloc(sizeof(char*) * count);
    if (*arr == NULL)
        exit(1);

    p = str;
    while (*p != '\0')
    {
        if (*p == c)
        {
            (*arr)[i] = (char*) malloc( sizeof(char) * token_len );
            if ((*arr)[i] == NULL)
                exit(1);

            token_len = 0;
            i++;
        }
        p++;
        token_len++;
    }
    (*arr)[i] = (char*) malloc( sizeof(char) * token_len );
    if ((*arr)[i] == NULL)
        exit(1);

    i = 0;
    p = str;
    t = ((*arr)[i]);
    while (*p != '\0')
    {
        if (*p != c && *p != '\0')
        {
            *t = *p;
            t++;
        }
        else
        {
            *t = '\0';
            i++;
            t = ((*arr)[i]);
        }
        p++;
    }

    return count;
}

How to use it:

int main (int argc, char ** argv)
{
    int i;
    char *s = "Hello, this is a test module for the string splitting.";
    int c = 0;
    char **arr = NULL;

    c = split(s, ' ', &arr);

    printf("found %d tokens.\n", c);

    for (i = 0; i < c; i++)
        printf("string #%d: %s\n", i, arr[i]);

    return 0;
}

userListComboBox.DataSource = userCache.ToList();
userListComboBox.DisplayMember = "Key";

Yes, it absolutely is - assuming you've got the appropriate security permissions. Use Field.setAccessible(true) first if you're accessing it from a different class.

import java.lang.reflect.*;

class Other
{
    private String str;
    public void setStr(String value)
    {
        str = value;
    }
}

class Test
{
    public static void main(String[] args)
        // Just for the ease of a throwaway test. Don't
        // do this normally!
        throws Exception
    {
        Other t = new Other();
        t.setStr("hi");
        Field field = Other.class.getDeclaredField("str");
        field.setAccessible(true);
        Object value = field.get(t);
        System.out.println(value);
    }
}

And no, you shouldn't normally do this... it's subverting the intentions of the original author of the class. For example, there may well be validation applied in any situation where the field can normally be set, or other fields may be changed at the same time. You're effectively violating the intended level of encapsulation.

StringBuffer is used to store character strings that will be changed (String objects cannot be changed). It automatically expands as needed. Related classes: String, CharSequence.

StringBuilder was added in Java 5. It is identical in all respects to StringBuffer except that it is not synchronized, which means that if multiple threads are accessing it at the same time, there could be trouble. For single-threaded programs, the most common case, avoiding the overhead of synchronization makes the StringBuilder very slightly faster.

Javascript cannot access the filesystem and check for existence. The only interaction with the filesystem is with loading js files and images (png/gif/etc).

Javascript is not the task for this

I find it useful.

var imgData = 'data:image/jpeg;base64,verylongbase64;'

var doc = new jsPDF();

doc.setFontSize(40);
doc.text(35, 25, "Octonyan loves jsPDF");
doc.addImage(imgData, 'JPEG', 15, 40, 180, 180);

I just did git reset --hard and lost all my uncommitted changes. Luckily, I use an editor (IntelliJ) and I was able to recover the changes from the Local History. Eclipse should allow you to do the same.

If you want to test the index to see if it works, here is the syntax:

SELECT *
FROM Table WITH(INDEX(Index_Name))

The WITH statement will force the index to be used.

You can use inspect.cleandoc to nicely format your printed SQL statement.

This works very well with your option 2.

Note: the print("-"*40) is only to demonstrate the superflous blank lines if you do not use cleandoc.

from inspect import cleandoc
def query():
    sql = """
        select field1, field2, field3, field4
        from table
        where condition1=1
        and condition2=2
    """

    print("-"*40)
    print(sql)
    print("-"*40)
    print(cleandoc(sql))
    print("-"*40)

query()

Output:

----------------------------------------

        select field1, field2, field3, field4
        from table
        where condition1=1
        and condition2=2

----------------------------------------
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
----------------------------------------

From the docs:

inspect.cleandoc(doc)

Clean up indentation from docstrings that are indented to line up with blocks of code.

All leading whitespace is removed from the first line. Any leading whitespace that can be uniformly removed from the second line onwards is removed. Empty lines at the beginning and end are subsequently removed. Also, all tabs are expanded to spaces.

Add a GitHub repository as remote origin (replace [] with your URL):

git remote add origin [[email protected]:...]

Switch to your master branch and copy it to develop branch:

git checkout master
git checkout -b develop

Push your develop branch to the GitHub develop branch (-f means force):

git push -f origin develop:develop

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

iframes cannot be responsive. You can make the iframe container responsive but not the content it is displaying since it is a webpage that has its own set height and width.

The example fiddle link works because it's displaying an embedded youtube video link that does not have a size declared.

In Additional

    Thread thread = new Thread(delegate() { download(i); });
    thread.Start();

Just use negative margins, in the second div say:

<div style="margin-top: -25px;">

And make sure to set the z-index property to get the layering you want.

This match 6 or more any chars but newline:

/^.{6,}$/

If you're talking about ASP.NET MVC then you should have a controller method that returns the following:

return Redirect("http://www.google.com");

Otherwise we need more info on the error you're getting in the redirect. I'd step through to make sure the url isn't empty.

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

The Clear method is defined as

    public void Clear() { 
        Text = null;
    } 

The Text property's setter starts with

        set { 
            if (value == null) { 
                value = "";
            } 

I assume this answers your question.

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.

I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.

Heres another good comparison of individual characteristics of each protocol.

I'm surprised that nobody has mentioned the use of this in the event handler. It works automatically in modern browsers and can be made to work in other browsers. If you use addEventListener or attachEvent to install your event handler, then you can make the value of this automatically be assigned to the object the created the event.

Further, the user of programmatically installed event handlers allows you to separate javascript code from HTML which is often considered a good thing.

Here's how you would do that in your code in plain javascript:

Remove the onmouseover="zoom()" from your HTML and install the event handler in your javascript like this:

// simplified utility function to register an event handler cross-browser
function setEventHandler(obj, name, fn) {
    if (typeof obj == "string") {
        obj = document.getElementById(obj);
    }
    if (obj.addEventListener) {
        return(obj.addEventListener(name, fn));
    } else if (obj.attachEvent) {
        return(obj.attachEvent("on" + name, function() {return(fn.call(obj));}));
    }
}

function zoom() {
    // you can use "this" here to refer to the object that caused the event
    // this here will refer to the calling object (which in this case is the <map>)
    console.log(this.id);
    document.getElementById("preview").src="http://photos.smugmug.com/photos/344290962_h6JjS-Ti.jpg";
}

// register your event handler
setEventHandler("nose", "mouseover", zoom);

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }
}

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

HTML:

<input name="name" id="name" type="text" value="Name" onfocus="clearField(this);" onblur="fillField(this);"/>

JS:

function clearField(input) {
  if(input.value=="Name") { //Only clear if value is "Name"
    input.value = "";
  }
}
function fillField(input) {
    if(input.value=="") {
        input.value = "Name";
    }
}

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

Virtualenv is a tool to create isolated Python environments.

Let's say you're working in 2 different projects, A and B. Project A is a web project and the team is using the following packages:

• Python 2.8.x
• Django 1.6.x

The project B is also a web project but your team is using:

• Python 2.7.x
• Django 1.4.x

The machine that you're working doesn't have any version of django, what should you do? Install django 1.4? django 1.6? If you install django 1.4 globally would be easy to point to django 1.6 to work in project A?

Virtualenv is your solution! You can create 2 different virtualenv's, one for project A and another for project B. Now, when you need to work in project A, just activate the virtualenv for project A, and vice-versa.

A better tip when using virtualenv is to install virtualenvwrapper to manage all the virtualenv's that you have, easily. It's a wrapper for creating, working, removing virtualenv's.

I see quite a few examples which depend on additional resources, but it seems like this would be the simplest solution: (which is what I used in my own project) which is basically just converting from an ArrayList to an Array and then to a List.

    List<Account> accounts = new ArrayList<>();

   public String accountList() 
   {
      Account[] listingArray = accounts.toArray(new Account[accounts.size()]);
      String listingString = Arrays.toString(listingArray);
      return listingString;
   }

This just happened to me in a string assignment using double quotes. I was missing a closing curly on a POST variable...

"for {$_POST['txtName'] on $date";

should have been

"for {$_POST['txtName']} on $date";

I can't explain why. I mean, I see the error that would break the code but I don't see why it references a class error.

Slight modification to Andry's answer, reducing duplicate type commands:

set "A=1" & set "B=2" & call :IF_AND
set "A=1" & set "B=3" & call :IF_AND
set "A=2" & set "B=2" & call :IF_AND
set "A=2" & set "B=3" & call :IF_AND

echo.

set "A=1" & set "B=2" & call :IF_OR
set "A=1" & set "B=3" & call :IF_OR
set "A=2" & set "B=2" & call :IF_OR
set "A=2" & set "B=3" & call :IF_OR

goto :eof

:IF_OR

(if /i not %A% EQU 1 (
   if /i not %B% EQU 2 (
      echo FALSE-
      type 2>nul
   )
)) && echo TRUE+

goto :eof

:IF_AND


(if /i %A% EQU 1 (
   if /i %B% EQU 2 (
      echo TRUE+
      type 2>nul
   )
)) && echo FALSE-

goto :eof

Just for completeness and those unaware XSL 1 has choose for multiple conditions.

<xsl:choose>
 <xsl:when test="expression">
  ... some output ...
 </xsl:when>
 <xsl:when test="another-expression">
  ... some output ...
 </xsl:when>
 <xsl:otherwise>
   ... some output ....
 </xsl:otherwise>
</xsl:choose>

I wanted a solution to have the output from stdout plus stderr written into a log file and stderr still on console. So I needed to duplicate the stderr output via tee.

This is the solution I found:

command 3>&1 1>&2 2>&3 1>>logfile | tee -a logfile

• First swap stderr and stdout
• then append the stdout to the log file
• pipe stderr to tee and append it also to the log file

Another way to dump data as file from table by DumpDataFromTable sproc

EXEC dbo.DumpDataFromTable
     @SchemaName = 'dbo'
    ,@TableName = 'YourTableName'
    ,@PathOut = N'c:\tmp\scripts\' -- folder must exist !!!'

Note: SQL must have permission to create files, if is not set-up then exec follow line once

EXEC sp_configure 'Ole Automation Procedures', 1; RECONFIGURE WITH OVERRIDE;

By this script you can call the sproc: DumpDataFromTable.sql and dump more tables in one go, instead of doing manually one by one from Management Studio

By default the format of generated scrip will be like

INSERT INTO <TableName> SELECT <Values>

Or you can change the generated format into

SELECT ... FROM

by setting variable @BuildMethod = 2

full sproc code:

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[DumpDataFromTable]') AND type in (N'P', N'PC'))
    DROP PROCEDURE dbo.[DumpDataFromTable]

One of the comments by @stivlo deserves to be an answer:

You can use the Amazon service http://checkip.amazonaws.com

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class IpChecker {

    public static String getIp() throws Exception {
        URL whatismyip = new URL("http://checkip.amazonaws.com");
        BufferedReader in = null;
        try {
            in = new BufferedReader(new InputStreamReader(
                    whatismyip.openStream()));
            String ip = in.readLine();
            return ip;
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

Late to the party but the answers above didn't seem to work for me.

My first tab fragment (uses getChildFragmentManager() for inner tabs) has the menu to show a search icon and uses android.support.v7.widget.SearchView to search within the inner tab fragment but navigating to other tabs (which also have inner tabs using getChildFragmentManager()) would not remove the search icon (as not required) and therefore still accessible with no function, maybe as I am using the below (ie outer main tabs with each inner tabs)

getChildFragmentManager(); 

However I use the below in my fragments containing/using the getChildFragmentManager() for inner tabs.

    //region onCreate
    @Override
    public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setRetainInstance(true);

    //access setHasOptionsMenu()
    setHasOptionsMenu(true);

    }
    //endregion onCreate

and then clear the menu item inside onPrepareOptionsMenu for fragments(search icon & functions)

    @Override
    public void onPrepareOptionsMenu(Menu menu) {

    super.onPrepareOptionsMenu(menu);

    //clear the menu/hide the icon & disable the search access/function ...
    //this will clear the menu entirely, so rewrite/draw the menu items after if needed
    menu.clear();

    }

Works well and navigating back to the tab/inner tab with the search icon functions re displays the search icon & functions.

Hope this helps...

Your function is failing because the groupby dataframe you end up with has a hierarchical index and two columns (Letter and N) so when you do .hist() it's trying to make a histogram of both columns hence the str error.

This is the default behavior of pandas plotting functions (one plot per column) so if you reshape your data frame so that each letter is a column you will get exactly what you want.

df.reset_index().pivot('index','Letter','N').hist()

The reset_index() is just to shove the current index into a column called index. Then pivot will take your data frame, collect all of the values N for each Letter and make them a column. The resulting data frame as 400 rows (fills missing values with NaN) and three columns (A, B, C). hist() will then produce one histogram per column and you get format the plots as needed.

Just to expand niko's answer:

You can reference any image via its URL. No matter where it is, as long as it's accesible you can use it as the src. Example:

Relative location:

<img src="images/image.png">

The image is sought relative to the document's location. If your document is at http://example.com/site/document.html, then your images folder should be on the same directory where your document.html file is.

Absolute location:

<img src="/site/images/image.png">
<img src="http://example.com/site/images/image.png">

or

<img src="http://another-example.com/images/image.png">

In this case, your image will be sought from the document site's root, so, if your document.html is at http://example.com/site/document.html, the root would be at http://example.com/ (or it's respective directory on the server's filesystem, commonly www/). The first two examples are the same, since both point to the same host, Think of the first / as an alias for your server's root. In the second case, the image is located in another host, so you'd have to specify the complete URL of the image.

Regarding /, . and ..:

The / symbol will always return the root of a filesystem or site.

The single point ./ points to the same directory where you are.

And the double point ../ will point to the upper directory, or the one that contains the actual working directory.

So you can build relative routes using them.

Examples given the route http://example.com/dir/one/two/three/ and your calling document being inside three/:

"./pictures/image.png"

or just

"pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/three/.

"../pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/.

"/pictures/image.png"

Will try to find a directory named pictures directly at / or example.com (which are the same), on the same level as directory.

Try:

new java.text.DecimalFormat("0").format( cell.getNumericCellValue() )

Should format the number correctly.

Web Application project model

• Provides the same Web project semantics as Visual Studio .NET Web projects. Has a project file (structure based on project files). Build model - all code in the project is compiled into a single assembly. Supports both IIS and the built-in ASP.NET Development Server. Supports all the features of Visual Studio 2005 (refactoring, generics, etc.) and of ASP.NET (master pages, membership and login, site navigation, themes, etc). Using FrontPage Server Extensions (FPSE) are no longer a requirement.

Web Site project model

• No project file (Based on file system).
• New compilation model.
• Dynamic compilation and working on pages without building entire site on each page view.
• Supports both IIS and the built-in ASP.NET Development Server.
• Each page has it's own assembly.
• Defferent code model.

Turing-completeness is not only about "defining functions" or "have ifs/loops/etc". For example, Haskell doesn't have "loop", lambda-calculus don't have "ifs", etc...

For example, this site: http://experthuman.com/programming-with-nothing. The author uses Ruby and create a "FizzBuzz" program with only closures (no strings, numbers, or anything like that)...

There are examples when people compute some arithmetical functions on Scala using only the type system

So, yes, in my opinion, CSS3+HTML is turing-complete (even if you can't exactly do any real computation with then without becoming crazy)

UPDATE users SET username='&username', password='&password' where id='&id'

This query will ask you to enter the username,password and id dynamically

I use Restler and Needle for production purposes. They are both much more powerful than native httprequest. It is possible to request with basic authentication, special header entry or even upload/download files.

As for post/get operation, they also are much simpler to use than raw ajax calls using httprequest.

needle.post('https://my.app.com/endpoint', {foo:'bar'}, 
    function(err, resp, body){
        console.log(body);
});

If you or some other fox who need to have link with Icon Image and text as link text beside the image see bellow code:

CSS

.linkWithImageIcon{

    Display:inline-block;
}
.MyLink{
  Background:#FF3300;
  width:200px;
  height:70px;
  vertical-align:top;
  display:inline-block; font-weight:bold;
} 

.MyLinkText{
  /*---The margin depends on how the image size is ---*/
  display:inline-block; margin-top:5px;
}

HTML

<a href="#" class="MyLink"><img src="./yourImageIcon.png" /><span class="MyLinkText">SIGN IN</span></a>

if you see the image the white portion is image icon and other is style this way you can create different buttons with any type of Icons you want to design

One can either use del or pop, but I prefer del, since you can specify index and slices, giving the user more control over the data.

For example, starting with the list shown, one can remove its last element with del as a slice, and then one can remove the last element from the result using pop.

>>> l = [1,2,3,4,5]
>>> del l[-1:]
>>> l
[1, 2, 3, 4]
>>> l.pop(-1)
4
>>> l
[1, 2, 3]

I have solved this issue by below steps:

1. Right click the Maven Project -> Build Path -> Configure Build Path
2. In Order and Export tab, you can see the message like '2 build path entries are missing'
3. Now select 'JRE System Library' and 'Maven Dependencies' checkbox
4. Click OK

Now you can see below in all type of Explorers (Package or Project or Navigator)

JavaSE and JavaEE both are computing platform which allows the developed software to run.

There are three main computing platform released by Sun Microsystems, which was eventually taken over by the Oracle Corporation. The computing platforms are all based on the Java programming language. These computing platforms are:

Java SE, i.e. Java Standard Edition. It is normally used for developing desktop applications. It forms the core/base API.

Java EE, i.e. Java Enterprise Edition. This was originally known as Java 2 Platform, Enterprise Edition or J2EE. The name was eventually changed to Java Platform, Enterprise Edition or Java EE in version 5. Java EE is mainly used for applications which run on servers, such as web sites.

Java ME, i.e. Java Micro Edition. It is mainly used for applications which run on resource constrained devices (small scale devices) like cell phones, most commonly games.

Just a recommendation:

I'd recommend using the DOM table implementation, it's very straight forward and easy to use, you really don't need jQuery for this task.

var table = document.getElementById('tblOne');

var rowLength = table.rows.length;

for(var i=0; i<rowLength; i+=1){
  var row = table.rows[i];

  //your code goes here, looping over every row.
  //cells are accessed as easy

  var cellLength = row.cells.length;
  for(var y=0; y<cellLength; y+=1){
    var cell = row.cells[y];

    //do something with every cell here
  }
}

Use this:

#head {
    border: green solid 1px;
    height:auto;
}    
#content{
            border: red solid 1px;
            overflow-y: scroll;
            height:150px;       
        }

Normally when querying a database with SQL and then fill a data-table with its results, it will never be a null Data table. You have the column headers filled with column information even if you returned 0 records.When one tried to process a data table with 0 records but with column information it will throw exception.To check the datatable before processing one could check like this.

if (DetailTable != null && DetailTable.Rows.Count>0)

conda should have given us a simple tool like cond env rename <old> <new> but it hasn't. Simply renaming the directory, as in this previous answer, of course, breaks the hardcoded hashbangs(#!). Hence, we need to go one more level deeper to achieve what we want.

rtg                      /home/tgowda/miniconda3/envs/rtg

Here I am trying to rename rtg --> unsup (please bear with those names, this is my real use case)

$ cd /home/tgowda/miniconda3/envs 
$ OLD=rtg
$ NEW=unsup
$ mv $OLD $NEW   # rename dir

$ conda env list
# conda environments:
#
base                  *  /home/tgowda/miniconda3
junkdetect               /home/tgowda/miniconda3/envs/junkdetect
unsup                    /home/tgowda/miniconda3/envs/unsup


$ conda activate $NEW
$ which python
  /home/tgowda/miniconda3/envs/unsup/bin/python

the previous answer reported upto this, but wait, we are not done yet! the pending task is, $NEW/bin dir has a bunch of executable scripts with hashbangs (#!) pointing to the $OLD env paths.

See jupyter, for example:

$ which jupyter
/home/tgowda/miniconda3/envs/unsup/bin/jupyter

$ head -1 $(which jupyter) # its hashbang is still looking at old
#!/home/tgowda/miniconda3/envs/rtg/bin/python

So, we can easily fix it with a sed

$ sed  -i.bak "s:envs/$OLD/bin:envs/$NEW/bin:" $NEW/bin/*  
# `-i.bak` created backups, to be safe

$ head -1 $(which jupyter) # check if updated
#!/home/tgowda/miniconda3/envs/unsup/bin/python
$ jupyter --version # check if it works
jupyter core     : 4.6.3
jupyter-notebook : 6.0.3

$ rm $NEW/bin/*.bak  # remove backups

Now we are done

I think it should be trivial to write a portable script to do all those and bind it to conda env rename old new.

I tested this on ubuntu. For whatever unforseen reasons, if things break and you wish to revert the above changes:

$ mv $NEW  $OLD
$ sed  -i.bak "s:envs/$NEW/bin:envs/$OLD/bin:" $OLD/bin/*

I have used in this way. Its Working fine!

$rules = [

            'password' => [

                    'required',

                    'string',

                    'min:6',

                'max:12',             // must be at least 8 characters in length

                ],

            'confirm_password' => 'required|same:password|min:6'

        ];

You need BEGIN ... END to create a block spanning more than one statement. So, if you wanted to do 2 things in one 'leg' of an IF statement, or if you wanted to do more than one thing in the body of a WHILE loop, you'd need to bracket those statements with BEGIN...END.

The GO keyword is not part of SQL. It's only used by Query Analyzer to divide scripts into "batches" that are executed independently.

You can do it with the HTMLWorker class (deprecated) like this:

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

or using the XMLWorker, (download from this jar) using this code:

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

BehaviorSubject is a type of subject, a subject is a special type of observable so you can subscribe to messages like any other observable. The unique features of BehaviorSubject are:

• It needs an initial value as it must always return a value on subscription even if it hasn't received a next()
• Upon subscription, it returns the last value of the subject. A regular observable only triggers when it receives an onnext
• at any point, you can retrieve the last value of the subject in a non-observable code using the getValue() method.

Unique features of a subject compared to an observable are:

• It is an observer in addition to being an observable so you can also send values to a subject in addition to subscribing to it.

In addition, you can get an observable from behavior subject using the asObservable() method on BehaviorSubject.

Observable is a Generic, and BehaviorSubject is technically a sub-type of Observable because BehaviorSubject is an observable with specific qualities.

Example with BehaviorSubject:

// Behavior Subject

// a is an initial value. if there is a subscription 
// after this, it would get "a" value immediately
let bSubject = new BehaviorSubject("a"); 

bSubject.next("b");

bSubject.subscribe(value => {
  console.log("Subscription got", value); // Subscription got b, 
                                          // ^ This would not happen 
                                          // for a generic observable 
                                          // or generic subject by default
});

bSubject.next("c"); // Subscription got c
bSubject.next("d"); // Subscription got d

Example 2 with regular subject:

// Regular Subject

let subject = new Subject(); 

subject.next("b");

subject.subscribe(value => {
  console.log("Subscription got", value); // Subscription wont get 
                                          // anything at this point
});

subject.next("c"); // Subscription got c
subject.next("d"); // Subscription got d

An observable can be created from both Subject and BehaviorSubject using subject.asObservable().

The only difference being you can't send values to an observable using next() method.

In Angular services, I would use BehaviorSubject for a data service as an angular service often initializes before component and behavior subject ensures that the component consuming the service receives the last updated data even if there are no new updates since the component's subscription to this data.

For Java, consider using Apache Commons FileUtils:

/**
 * Convert a file to base64 string representation
 */
public String fileToBase64(File file) throws IOException {
    final byte[] bytes = FileUtils.readFileToByteArray(file);
    return Base64.getEncoder().encodeToString(bytes);
}

/**
 * Convert base64 string representation to a file
 */
public void base64ToFile(String base64String, String filePath) throws IOException {
    byte[] bytes = Base64.getDecoder().decode(base64String);
    FileUtils.writeByteArrayToFile(new File(filePath), bytes);
}

In addittion, you can do in a Fragment (for example when getting server data failed):

 getView().setVisibility(View.GONE);

For ASP.NET Core 3.1 you can follow this guide:

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-3.1

When you create a new ASP.NET Core 3.1 project you will have the following configuration line in Program.cs:

Host.CreateDefaultBuilder(args)

This enables the following:

1. ChainedConfigurationProvider : Adds an existing IConfiguration as a source. In the default configuration case, adds the host configuration and setting it as the first source for the app configuration.
2. appsettings.json using the JSON configuration provider.
3. appsettings.Environment.json using the JSON configuration provider. For example, appsettings.Production.json and appsettings.Development.json.
4. App secrets when the app runs in the Development environment.
5. Environment variables using the Environment Variables configuration provider.
6. Command-line arguments using the Command-line configuration provider.

This means you can inject IConfiguration and fetch values with a string key, even nested values. Like IConfiguration["Parent:Child"];

Example:

appsettings.json

{
  "ApplicationInsights":
    {
        "Instrumentationkey":"putrealikeyhere"
    }
}

WeatherForecast.cs

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };

    private readonly ILogger<WeatherForecastController> _logger;
    private readonly IConfiguration _configuration;

    public WeatherForecastController(ILogger<WeatherForecastController> logger, IConfiguration configuration)
    {
        _logger = logger;
        _configuration = configuration;
    }

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {
        var key = _configuration["ApplicationInsights:InstrumentationKey"];

        var rng = new Random();
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
        {
            Date = DateTime.Now.AddDays(index),
            TemperatureC = rng.Next(-20, 55),
            Summary = Summaries[rng.Next(Summaries.Length)]
        })
        .ToArray();
    }
}

if you don't have a good copy of your php5.ini file in your home directory (a predicament that I recently found myself in), you'll need to follow a little multi-step process to make your changes.

1. Create a little code snippet to look at the output of the phpinfo() call. This is simple, and there are multiple web-sites that describe this process.

2. Examine the output of phpinfo() for the row which contains Configuration File (php.ini) Path. Mine was in /usr/local/lib, but your's may be a different path (depends on hosting level purchased).

3. GoDaddy will NOT simply copy this file into your home directory for you --as silly as that sounds! But, you can write a little php program to copy this php.ini file into your home directory. The guy at https://www.jabari-holder.com/blog/how-to-get-godaddys-php5-ini-file/ has a drop-box with this code snippet, if you care to use it. Just take care to modify two things:

   • a. change the path you read 'from' to match the path you uncovered in Step 2.

   • b. change the output file-name to something of your choosing. You're going to re-name this file in a later step anyway. Let's call our copied file Foo.ini (but it can be anything).

4. Rename Foo.ini to .user.ini (for most GoDaddy account types).

Here is another library.

Changes required are -

1. Add sorttable js
   

2. Add class name sortable to table.

Click the table headers to sort the table accordingly:

<script src="https://www.kryogenix.org/code/browser/sorttable/sorttable.js"></script>

<table class="sortable">
  <tr>
    <th>Name</th>
    <th>Address</th>
    <th>Sales Person</th>
  </tr>

  <tr class="item">
    <td>user:0001</td>
    <td>UK</td>
    <td>Melissa</td>
  </tr>
  <tr class="item">
    <td>user:0002</td>
    <td>France</td>
    <td>Justin</td>
  </tr>
  <tr class="item">
    <td>user:0003</td>
    <td>San Francisco</td>
    <td>Judy</td>
  </tr>
  <tr class="item">
    <td>user:0004</td>
    <td>Canada</td>
    <td>Skipper</td>
  </tr>
  <tr class="item">
    <td>user:0005</td>
    <td>Christchurch</td>
    <td>Alex</td>
  </tr>

I think you have to include jQuery to use responseJSON.

Without jQuery, you could try with responseText and try like eval("("+req.responseText+")");

UPDATE:Please read the comment regarding eval, you can test with eval, but don't use it in working extension.

OR

use json_parse : it does not use eval

If I am working on an API to draw shapes, I may want to use DirectX or graphic calls, or OpenGL. So, I will create an interface, which will abstract my implementation from what you call.

So you call a factory method: MyInterface i = MyGraphics.getInstance(). Then, you have a contract, so you know what functions you can expect in MyInterface. So, you can call i.drawRectangle or i.drawCube and know that if you swap one library out for another, that the functions are supported.

This becomes more important if you are using Dependency Injection, as then you can, in an XML file, swap implementations out.

So, you may have one crypto library that can be exported that is for general use, and another that is for sale only to American companies, and the difference is in that you change a config file, and the rest of the program isn't changed.

This is used a great deal with collections in .NET, as you should just use, for example, List variables, and don't worry whether it was an ArrayList or LinkedList.

As long as you code to the interface then the developer can change the actual implementation and the rest of the program is left unchanged.

This is also useful when unit testing, as you can mock out entire interfaces, so, I don't have to go to a database, but to a mocked out implementation that just returns static data, so I can test my method without worrying if the database is down for maintenance or not.

Thumbs up first before use codes please!!! Create an image that fully cover the whole tab bar item for each item. This is needed to use the image you created as a tab bar item button. Be sure to make the height/width ratio be the same of each tab bar item too. Then:

UITabBarController *tabBarController = (UITabBarController *)self;
UITabBar *tabBar = tabBarController.tabBar;
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];

int x,y;

x = tabBar.frame.size.width/4 + 4; //when doing division, it may be rounded so that you need to add 1 to each item; 
y = tabBar.frame.size.height + 10; //the height return always shorter, this is compensated by added by 10; you can change the value if u like.

//because the whole tab bar item will be replaced by an image, u dont need title
tabBarItem1.title = @"";
tabBarItem2.title = @"";
tabBarItem3.title = @"";
tabBarItem4.title = @"";

[tabBarItem1 setFinishedSelectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-select.png"] scaledToSize:CGSizeMake(x, y)] withFinishedUnselectedImage:[self imageWithImage:[UIImage imageNamed:@"item1-deselect.png"] scaledToSize:CGSizeMake(x, y)]];//do the same thing for the other 3 bar item

Highlight table name in the console and press ALT+F1

no. if you must then use a user defined function to which you can pass parameters into.

You can pass a type as an argument, but to do so you must use typeof:

foo.GetColumnValues(dm.mainColumn, typeof(int))

The method would need to accept a parameter with type Type.

where the GetColumns method will call a different method inside depending on the type passed.

If you want this behaviour then you should not pass the type as an argument but instead use a type parameter.

foo.GetColumnValues<int>(dm.mainColumn)

No one seems to have included the which function. It can also prove useful for filtering.

expr[which(expr$cell == 'hesc'),]

This will also handle NAs and drop them from the resulting dataframe.

Running this on a 9840 by 24 dataframe 50000 times, it seems like the which method has a 60% faster run time than the %in% method.

PHP runs on the server before the page is sent to the user, JavaScript is run on the user's computer once it is received, so the PHP script has already executed.

If you want to pass a JavaScript value to a PHP script, you'd have to do an XMLHttpRequest to send the data back to the server.

Here's a previous question that you can follow for more information: Ajax Tutorial

Now if you just need to pass a form value to the server, you can also just do a normal form post, that does the same thing, but the whole page has to be refreshed.

<?php
if(isset($_POST))
{
  print_r($_POST);
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
  <input type="text" name="data" value="1" />
  <input type="submit" value="Submit" />
</form>

Clicking submit will submit the page, and print out the submitted data.

I am running a spark cluster, on CentOS VM, which is installed from cloudera yum packages.

Had to set the following variables to run pyspark.

export SPARK_HOME=/usr/lib/spark;
export PYTHONPATH=$SPARK_HOME/python:$SPARK_HOME/python/lib/py4j-0.9-src.zip:$PYTHONPATH

If you are using maven project then you just need to add the jstl-1.2 jar in your dependency. If you are simply adding the jar to your project then it's possible that jar file is not added in your project project artifact. You simply need to add the jar file in WEB-INF/lib file.

This is how your project should look when jstl is not added to the artifact. Just hit the fix button and intellij will add the jar file in the above mentioned path. Run the project and bang.

To remove all the constraints from the DB:

SELECT 'ALTER TABLE ' + Table_Name  +' DROP CONSTRAINT ' + Constraint_Name
FROM Information_Schema.CONSTRAINT_TABLE_USAGE

The tab character is \t. Notice the use of " instead of '.

$chunk = "abc\tdef\tghi";

PHP Strings - Double quoted

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

...

\t horizontal tab (HT or 0x09 (9) in ASCII)

Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.

Here is a good example in Python3.

  >>> a = input("What is your name?")
  What is your name?Peter

  >>> b = input("Where are you from?")
  Where are you from?DE

  >>> print("So you are %s of %s" % (a, b))
  So you are Peter of DE

it depends on how you trigger the event. the key you are looking is textbox.clientid.

x.aspx code

<script type="text/javascript">

   function disable_textbox(tid) {
        var mytextbox = document.getElementById(tid);
         mytextbox.disabled=false
   }
</script>

code behind x.aspx.cs

    string frameScript = "<script language='javascript'>" + "disable_textbox(" + tx.ClientID  ");</script>";
    Page.ClientScript.RegisterStartupScript(Page.GetType(), "FrameScript", frameScript);

 public ActionResult Save(Director director)
        {
          // IsActive my model property same name give in cshtml
//IsActive <input type="checkbox" id="IsActive" checked="checked" value="true" name="IsActive" 
            if(ModelState.IsValid)
            {
                DirectorVM ODirectorVM = new DirectorVM();
                ODirectorVM.SaveData(director);
                return RedirectToAction("Display");
            }
            return RedirectToAction("Add");
        }

Over time, I have found that extracting text from PDFs in a structured format is tough business. However if you are looking for an easy solution, you might want to consider XPDF tool pdftotext.

Pseudocode to extract the text would include:

1. Using SHELL VBA statement to extract the text from PDF to a temporary file using XPDF
2. Using sequential file read statements to read the temporary file contents into a string
3. Pasting the string into Excel

Simplified example below:

    Sub ReadIntoExcel(PDFName As String)
        'Convert PDF to text
        Shell "C:\Utils\pdftotext.exe -layout " & PDFName & " tempfile.txt"

        'Read in the text file and write to Excel
        Dim TextLine as String
        Dim RowNumber as Integer
        Dim F1 as Integer
        RowNumber = 1
        F1 = Freefile()
        Open "tempfile.txt" for Input as #F1
            While Not EOF(#F1)
                Line Input #F1, TextLine
                ThisWorkbook.WorkSheets(1).Cells(RowNumber, 1).Value = TextLine
                RowNumber = RowNumber + 1
            Wend
        Close #F1
    End Sub

I had an issue with XCode 10.2 specifying the correct iOS simulator version number, so used:

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

As other option, you can do something like below

Group   Valuation   amount
    0   BKB Tube    156
    1   BKB Tube    143
    2   BKB Tube    67
    3   BAC Tube    176
    4   BAC Tube    39
    5   JDK Tube    75
    6   JDK Tube    35
    7   JDK Tube    155
    8   ETH Tube    38
    9   ETH Tube    56

Below script, you can use for above data

import pandas as pd    
data = pd.read_csv("daata1.csv")
bytreatment = data.groupby('Group')
bytreatment['amount'].sum()

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

You have to edit three files to set a permanent environment variable as follow:

• ~/.bashrc

  When you open any terminal window this file will be run. Therefore, if you wish to have a permanent environment variable in all of your terminal windows you have to add the following line at the end of this file:

  export DISPLAY=0
  

• ~/.profile

  Same as bashrc you have to put the mentioned command line at the end of this file to have your environment variable in every login of your OS.

• /etc/environment

  If you want your environment variable in every window or application (not just terminal window) you have to edit this file. Add the following command at the end of this file:

  DISPLAY=0
  

  Note that in this file you do not have to write export command

Normally you have to restart your computer to apply these changes. But you can apply changes in bashrc and profile by these commands:

$ source ~/.bashrc
$ source ~/.profile

But for /etc/environment you have no choice but restarting (as far as I know)

A Simple Solution

I've written a simple script for these procedures to do all those work. You just have to set the name and value of your environment variable.

#!/bin/bash
echo "Enter variable name: "
read variable_name
echo "Enter variable value: "
read variable_value
echo "adding " $variable_name " to environment variables: " $variable_value
echo "export "$variable_name"="$variable_value>>~/.bashrc
echo $variable_name"="$variable_value>>~/.profile
echo $variable_name"="$variable_value>>/etc/environment
source ~/.bashrc
source ~/.profile
echo "do you want to restart your computer to apply changes in /etc/environment file? yes(y)no(n)"
read restart
case $restart in
    y) sudo shutdown -r 0;;
    n) echo "don't forget to restart your computer manually";;
esac
exit

Save these lines in a shfile then make it executable and just run it!

For most cases (long for floats, long long for double and long double):

long a{ std::lround(1.5f) }; //2l
long long b{ std::llround(std::floor(1.5)) }; //1ll

<?php $data = "<div><p>Welcome to my PHP class, we are glad you are here</p></div>"; echo strip_tags($data); ?>

Or if you have a content coming from the database;

<?php $data = strip_tags($get_row['description']); ?> <?=substr($data, 0, 100) ?><?php if(strlen($data) > 100) { ?>...<?php } ?>

Just to add on, in the hope to make the solution more complete.

The logic by @sheki already gave the correct way of reversing an integer in Java. If you assume the input you use and the result you get always fall within the range [-2147483648, 2147483647], you should be safe to use the codes by @sheki. Otherwise, it'll be a good practice to catch the exception.

Java 8 introduced the methods addExact, subtractExact, multiplyExact and toIntExact. These methods will throw ArithmeticException upon overflow. Therefore, you can use the below implementation to implement a clean and a bit safer method to reverse an integer. Generally we can use the mentioned methods to do mathematical calculation and explicitly handle overflow issue, which is always recommended if there's a possibility of overflow in the actual usage.

public int reverse(int x) {
    int result = 0;

    while (x != 0){
        try {
            result = Math.multiplyExact(result, 10);
            result = Math.addExact(result, x % 10);
            x /= 10;
        } catch (ArithmeticException e) {
            result = 0; // Exception handling
            break;
        }
    }

    return result;
}

I know I am late to answer this question but I would like to add something to answer of @Ethan, the highest voted and accepted answer.

We can use yargs to get the command line parameter and with that we can also add our own alias for some parameters like follow.

var args = require('yargs')
    .alias('r', 'release')
    .alias('d', 'develop')
    .default('release', false)
    .argv;

Kindly refer this link for more details. https://github.com/yargs/yargs/blob/HEAD/docs/api.md

Following is use of alias as per given in documentation of yargs. We can also find more yargs function there and can make the command line passing experience even better.

.alias(key, alias)

Set key names as equivalent such that updates to a key will propagate to aliases and vice-versa.

Optionally .alias() can take an object that maps keys to aliases. Each key of this object should be the canonical version of the option, and each value should be a string or an array of strings.

Based on the answer by Eduard Florinescu, but with newer code and the missing imports added:

The meaning of this exception is explained here: https://bz.apache.org/bugzilla/show_bug.cgi?id=27829

Summary: Java dies, Tomcat shut down hook is called, exception is thrown.

So if a firewall prevents the shutdown message from reaching Tomcat, Java will eventually die first (ex during system reboot/shutdown), and the exception will appear.

There are other possibilities.

In my case, my problem had something to do with my initscript (Linux) being incorrectly installed. That implied Java was getting killed by the OS during shutdown/reboot and not as a result of the script. The solution as simple as this:

chkconfig --del initscript
chkconfig --add initscript

Before the fix I had the following in rc.d:

find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc2.d/S85initscript
/etc/rc.d/rc3.d/S85initscript
/etc/rc.d/rc4.d/S85initscript
/etc/rc.d/rc5.d/S85initscript

After the fix:

find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc0.d/K15initscript
/etc/rc.d/rc1.d/K15initscript
/etc/rc.d/rc2.d/K15initscript
/etc/rc.d/rc3.d/K15initscript
/etc/rc.d/rc4.d/K15initscript
/etc/rc.d/rc5.d/S85initscript
/etc/rc.d/rc6.d/K15initscript

Conclusion: if you get this exception, make sure Tomcat is shutdown properly, not as a result of Java being terminated. Check your firewall, shutdown scripts etc.

It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.

My pracitce is in the Dockerfile start a shell which will not exit immediately CMD [ "sh", "-c", "service ssh start; bash"], then run docker run -dit image_name. This way the (ssh) service and container is up running.

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

Lets make it as simple if you don't want to hardcode the value of year and month and you want to take the value from current date and time:

Date d = new Date();
String myDate = new SimpleDateFormat("dd/MM/yyyy").format(d);
int iDayFromDate = Integer.parseInt(myDate.substring(0, 2));
int iMonthFromDate = Integer.parseInt(myDate.substring(3, 5));
int iYearfromDate = Integer.parseInt(myDate.substring(6, 10));

YearMonth CurrentYear = YearMonth.of(iYearfromDate, iMonthFromDate);
int lengthOfCurrentMonth = CurrentYear.lengthOfMonth();
System.out.println("Total number of days in current month is " + lengthOfCurrentMonth );

unsigned mod(int a, unsigned b) {
    return (a >= 0 ? a % b : b - (-a) % b);
}

I wanted to upvote and comment on jmbertucci's answer, but I'm not yet to be trusted with the controls. I had the same issue and resolved it as he said. If you are using Bootstrap 3.0, edit the LESS variables in variables.less The responsive break points are set around line 200:

@screen-xs:                  480px;
@screen-phone:               @screen-xs;

// Small screen / tablet
@screen-sm:                  768px;
@screen-tablet:              @screen-sm;

// Medium screen / desktop
@screen-md:                  992px;
@screen-desktop:             @screen-md;

// Large screen / wide desktop
@screen-lg:                  1200px;
@screen-lg-desktop:          @screen-lg;

// So media queries don't overlap when required, provide a maximum
@screen-xs-max:              (@screen-sm - 1);
@screen-sm-max:              (@screen-md - 1);
@screen-md-max:              (@screen-lg - 1);

Then set the collapse value for the navbar using the @grid-float-breakpoint variable at about line 232. By default it's set to @screen-tablet . If you want you can use a pixel value, but I prefer to use the LESS variables.

Simply call the ordinal() method on an enum value, to retrieve its corresponding number. There's no need to declare an addition attribute with its value, each enumerated value gets its own number by default, assigned starting from zero, incrementing by one for each value in the same order they were declared.

You shouldn't depend on the int value of an enum, only on its actual value. Enums in Java are a different kind of monster and are not like enums in C, where you depend on their integer code.

Regarding the example you provided in the question, Font.PLAIN works because that's just an integer constant of the Font class. If you absolutely need a (possibly changing) numeric code, then an enum is not the right tool for the job, better stick to numeric constants.

I'm unable to reproduce your problem but have you tried converting it to an integer first?

image_name_data['id'] = image_name_data['id'].astype(int).astype('str')

Then, regarding your more general question you could use map (as in this answer). In your case:

image_name_data['id'] = image_name_data['id'].map('{:.0f}'.format)

Just tell request that you are using json:true and forget about header and parse

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'GET',
    json:true
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

and the same for post

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'POST',
    json: {"name":"John", "lastname":"Doe"}
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

Building on the previous, my preferred approach (since this is a frequently performed action) is to wrap the wait cursor code in an IDisposable helper class so it can be used with using() (one line of code), take optional parameters, run the code within, then clean up (restore cursor) afterwards.

public class CursorWait : IDisposable
{
    public CursorWait(bool appStarting = false, bool applicationCursor = false)
    {
        // Wait
        Cursor.Current = appStarting ? Cursors.AppStarting : Cursors.WaitCursor;
        if (applicationCursor) Application.UseWaitCursor = true;
    }

    public void Dispose()
    {
        // Reset
        Cursor.Current = Cursors.Default;
        Application.UseWaitCursor = false;
    }
}

Usage:

using (new CursorWait())
{
    // Perform some code that shows cursor
}

pandas.isnull() (also pd.isna(), in newer versions) checks for missing values in both numeric and string/object arrays. From the documentation, it checks for:

NaN in numeric arrays, None/NaN in object arrays

Quick example:

import pandas as pd
import numpy as np
s = pd.Series(['apple', np.nan, 'banana'])
pd.isnull(s)
Out[9]: 
0    False
1     True
2    False
dtype: bool

The idea of using numpy.nan to represent missing values is something that pandas introduced, which is why pandas has the tools to deal with it.

Datetimes too (if you use pd.NaT you won't need to specify the dtype)

In [24]: s = Series([Timestamp('20130101'),np.nan,Timestamp('20130102 9:30')],dtype='M8[ns]')

In [25]: s
Out[25]: 
0   2013-01-01 00:00:00
1                   NaT
2   2013-01-02 09:30:00
dtype: datetime64[ns]``

In [26]: pd.isnull(s)
Out[26]: 
0    False
1     True
2    False
dtype: bool

Simply call your Action Method by using Javascript as shown below:

var id = model.Id; //if you want to pass an Id parameter
window.location.href = '@Url.Action("Action", "Controller")/' + id;

Hope this helps...

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:60 target:self selector:@selector(timerCalled) userInfo:nil repeats:NO];

-(void)timerCalled
{
     NSLog(@"Timer Called");
     // Your Code
}

In addition to previous answers describing how to enable general logging, I had to modify one additional variable in my vanilla MySql 5.6 installation before any SQL was written to the log:

SET GLOBAL log_output = 'FILE';

The default setting was 'NONE'.

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

I am only submitting this answer because people expressed concerns over browsers and maintaining the order of objects. I recognize that it is not the most efficient way to accomplish the goal.

Having said this, I broke the problem down into two functions for readability.

// The following function is used for each itertion in the function updateObjectsInArr
const newObjInInitialArr = function(initialArr, newObject) {
  let id = newObject.id;
  let newArr = [];
  for (let i = 0; i < initialArr.length; i++) {
    if (id === initialArr[i].id) {
      newArr.push(newObject);
    } else {
      newArr.push(initialArr[i]);
    }
  }
  return newArr;
};

const updateObjectsInArr = function(initialArr, newArr) {
    let finalUpdatedArr = initialArr;  
    for (let i = 0; i < newArr.length; i++) {
      finalUpdatedArr = newObjInInitialArr(finalUpdatedArr, newArr[i]);
    }

    return finalUpdatedArr
}

const revisedArr = updateObjectsInArr(arr1, arr2);

I believe you have libx264 installed and configured with ffmpeg to convert video to h264... Then you can try with -vcodec libx264... The -format option is for showing available formats, this is not a conversion option I think...

With mysql 5.7, date value like 0000-00-00 00:00:00 is not allowed.

If you want to allow it, you have to update your my.cnf like:

sudo nano /etc/mysql/my.cnf

find

[mysqld]

Add after:

sql_mode="NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Restart mysql service:

sudo service mysql restart

Done!

I'm using this function to format US numbers.

function formatUsPhone(phone) {

    var phoneTest = new RegExp(/^((\+1)|1)? ?\(?(\d{3})\)?[ .-]?(\d{3})[ .-]?(\d{4})( ?(ext\.? ?|x)(\d*))?$/);

    phone = phone.trim();
    var results = phoneTest.exec(phone);
    if (results !== null && results.length > 8) {

        return "(" + results[3] + ") " + results[4] + "-" + results[5] + (typeof results[8] !== "undefined" ? " x" + results[8] : "");

    }
    else {
         return phone;
    }
}

It accepts almost all imaginable ways of writing a US phone number. The result is formatted to a standard form of (987) 654-3210 x123

It's good to know the differences between margin and padding. Here are some differences:

• Margin is outer space of an element, while padding is inner space of an element.

• Margin is the space outside the border of an element, while padding is the space inside the border of it.

• Margin accepts the value of auto: margin: auto, but you can't set padding to auto.

• Margin can be set to any number, but padding must be non-negative.

• When you style an element, padding will also be affected (e.g. background color), but not margin.

According to the below article:

http://tools.ietf.org/html/rfc3696 (Page 6, Section 3)

It's mentioned that:

"There is a length limit on email addresses. That limit is a maximum of 64 characters (octets) in the "local part" (before the "@") and a maximum of 255 characters (octets) in the domain part (after the "@") for a total length of 320 characters. Systems that handle email should be prepared to process addresses which are that long, even though they are rarely encountered."

So, the maximum total length for an email address is 320 characters ("local part": 64 + "@": 1 + "domain part": 255 which sums to 320)

You can use the beforeSend callback to set additional parameters (The XMLHTTPRequest object is passed to it as its only parameter).

Just so you know, this type of cross-domain request will not work in a normal site scenario and not with any other browser. I don't even know what security limitations FF 3.5 imposes as well, just so you don't beat your head against the wall for nothing:

$.ajax({
    url: 'http://bar.other',
    data: { whatever:'cool' },
    type: 'GET',
    beforeSend: function(xhr){
       xhr.withCredentials = true;
    }
});

One more thing to beware of, is that jQuery is setup to normalize browser differences. You may find that further limitations are imposed by the jQuery library that prohibit this type of functionality.

Check out this sample: http://jsfiddle.net/Epgvc/1/

The extended configuration section in a previous response with

listed works but I did not have to use

<staticLogFileName value="false" /> 

. I think the RollingAppender must (logically) ignore that setting since by definition the file gets rebuilt each day when the application restarts/reused. Perhaps it does matter for immediate rollover EVERY time the application starts.

To see if the given object is a ES6 Promise, we can make use of this predicate:

function isPromise(p) {
  return p && Object.prototype.toString.call(p) === "[object Promise]";
}

Calling toString directly from the Object.prototype returns a native string representation of the given object type which is "[object Promise]" in our case. This ensures that the given object

• Bypasses false positives such as..:
  • Self-defined object type with the same constructor name ("Promise").
  • Self-written toString method of the given object.
• Works across multiple environment contexts (e.g. iframes) in contrast to instanceof or isPrototypeOf.

However, any particular host object, that has its tag modified via Symbol.toStringTag, can return "[object Promise]". This may be the intended result or not depending on the project (e.g. if there is a custom Promise implementation).

To see if the object is from a native ES6 Promise, we can use:

function isNativePromise(p) {
  return p && typeof p.constructor === "function"
    && Function.prototype.toString.call(p.constructor).replace(/\(.*\)/, "()")
    === Function.prototype.toString.call(/*native object*/Function)
      .replace("Function", "Promise") // replacing Identifier
      .replace(/\(.*\)/, "()"); // removing possible FormalParameterList 
}

According to this and this section of the spec, the string representation of function should be:

"function Identifier ( FormalParameterList_opt ) { FunctionBody }"

which is handled accordingly above. The FunctionBody is [native code] in all major browsers.

MDN: Function.prototype.toString

This works across multiple environment contexts as well.

public static void formatDouble(double myDouble){
 NumberFormat numberFormatter = new DecimalFormat("##.000");
 String result = numberFormatter.format(myDouble);
 System.out.println(result);
}

For instance, if the double value passed into the formatDouble() method is 345.9372, the following will be the result: 345.937 Similarly, if the value .7697 is passed to the method, the following will be the result: .770

The format is YYYY-MM-DD. You cannot change it.

$('#myinput').val('2013-12-31'); sets value

My "user interface" response is: Are you sure your users want their browsers flashing, or do you think that's what they want? If I were the one using your software, I know I'd be annoyed if these alerts happened very often and got in my way.

If you're sure you want to do it this way, use a javascript alert box. That's what Google Calendar does for event reminders, and they probably put some thought into it.

A web page really isn't the best medium for need-to-know alerts. If you're designing something along the lines of "ZOMG, the servers are down!" alerts, automated e-mails or SMS messages to the right people might do the trick.

Simple convert ? to ! fixed my issue:

You can't get value when calling getJSON, only after response.

var myjson;
$.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
    myjson = json;
});

While you cannot modify a column as such, you may operate on a column and return a new DataFrame reflecting that change. For that you'd first create a UserDefinedFunction implementing the operation to apply and then selectively apply that function to the targeted column only. In Python:

from pyspark.sql.functions import UserDefinedFunction
from pyspark.sql.types import StringType

name = 'target_column'
udf = UserDefinedFunction(lambda x: 'new_value', StringType())
new_df = old_df.select(*[udf(column).alias(name) if column == name else column for column in old_df.columns])

new_df now has the same schema as old_df (assuming that old_df.target_column was of type StringType as well) but all values in column target_column will be new_value.

What you are looking for is a pseudo-element that doesn't exist. There is :first-letter and :first-line, but no :first-word.

You can of course do this with JavaScript. Here's some code I found that does this: http://www.dynamicsitesolutions.com/javascript/first-word-selector/

Try this...

<div class="row">
    <div class="col-xs-3">
        Menu
    </div>
    <div class="col-xs-9">
        <div class="row">
          <div class="col-sm-4 col-sm-push-8">
          Right content
          </div>
          <div class="col-sm-8 col-sm-pull-4">
          Content
          </div>
       </div>
    </div>

String.Format adds many options in addition to the concatenation operators, including the ability to specify the specific format of each item added into the string.

For details on what is possible, I'd recommend reading the section on MSDN titled Composite Formatting. It explains the advantage of String.Format (as well as xxx.WriteLine and other methods that support composite formatting) over normal concatenation operators.

The problem is, that openssl -verify does not do the job.

As Priyadi mentioned, openssl -verify stops at the first self signed certificate, hence you do not really verify the chain, as often the intermediate cert is self-signed.

I assume that you want to be 101% sure, that the certificate files are correct before you try to install them in the productive web service. This recipe here performs exactly this pre-flight-check.

Please note that the answer of Peter is correct, however the output of openssl -verify is no clue that everything really works afterwards. Yes, it might find some problems, but quite not all.

Here is a script which does the job to verify a certificate chain before you install it into Apache. Perhaps this can be enhanced with some of the more mystic OpenSSL magic, but I am no OpenSSL guru and following works:

trap 'kick' 0

    'Verify return code: '*)    return 1;;

}

BND="$ARG.bundle"

for a in "$KEY" "$CRT" "$BND"
do
    [ -s "$a" ] || OOPS "missing $a"
done

serve
check && echo "!!! =========> CA-Bundle is not needed! <========"
echo
serve -CAfile "$BND"
check
ret=$?
kick

echo
case $ret in
0)  echo "EVERYTHING OK"
    echo "SSLCertificateKeyFile $KEY"
    echo "SSLCertificateFile    $CRT"
    echo "SSLCACertificateFile  $BND"
    ;;
*)  echo "!!! =========> something is wrong, verification failed! <======== ($ret)";;
esac

exit $ret

Note that the output after EVERYTHING OK is the Apache setting, because people using NginX or haproxy usually can read and understand this perfectly, too ;)

There is a GitHub Gist of this which might have some updates

Prerequisites of this script:

• You have the trusted CA root data in /etc/ssl/certs as usual for example on Ubuntu
• Create a directory DIR where you store 3 files:
  • DIR/certificate.crt which contains the certificate
  • DIR/certificate.key which contains the secret key for your webservice (without passphrase)
  • DIR/certificate.bundle which contains the CA-Bundle. On how to prepare the bundle, see below.
• Now run the script: ./check DIR/certificate (this assumes that the script is named check in the current directory)
• There is a very unlikely case that the script outputs CA-Bundle is not needed. This means, that you (read: /etc/ssl/certs/) already trusts the signing certificate. But this is highly unlikely in the WWW.
• For this test port 4433 must be unused on your workstation. And better only run this in a secure environment, as it opens port 4433 shortly to the public, which might see foreign connects in a hostile environment.

How to create the certificate.bundle file?

In the WWW the trust chain usually looks like this:

• trusted certificate from /etc/ssl/certs
• unknown intermediate certificate(s), possibly cross signed by another CA
• your certificate (certificate.crt)

Now, the evaluation takes place from bottom to top, this means, first, your certificate is read, then the unknown intermediate certificate is needed, then perhaps the cross-signing-certificate and then /etc/ssl/certs is consulted to find the proper trusted certificate.

The ca-bundle must be made up in excactly the right processing order, this means, the first needed certificate (the intermediate certificate which signs your certificate) comes first in the bundle. Then the cross-signing-cert is needed.

Usually your CA (the authority who signed your certificate) will provide such a proper ca-bundle-file already. If not, you need to pick all the needed intermediate certificates and cat them together into a single file (on Unix). On Windows you can just open a text editor (like notepad.exe) and paste the certificates into the file, the first needed on top and following the others.

There is another thing. The files need to be in PEM format. Some CAs issue DER (a binary) format. PEM is easy to spot: It is ASCII readable. For mor on how to convert something into PEM, see How to convert .crt to .pem and follow the yellow brick road.

Example:

You have:

• intermediate2.crt the intermediate cert which signed your certificate.crt
• intermediate1.crt another intermediate cert, which singed intermediate2.crt
• crossigned.crt which is a cross signing certificate from another CA, which signed intermediate1.crt
• crossintermediate.crt which is another intermediate from the other CA which signed crossigned.crt (you probably will never ever see such a thing)

Then the proper cat would look like this:

cat intermediate2.crt intermediate1.crt crossigned.crt crossintermediate.crt > certificate.bundle

And how can you find out which files are needed or not and in which sequence?

Well, experiment, until the check tells you everything is OK. It is like a computer puzzle game to solve the riddle. Every. Single. Time. Even for pros. But you will get better each time you need to do this. So you are definitively not alone with all that pain. It's SSL, ya' know? SSL is probably one of the worst designs I ever saw in over 30 years of professional system administration. Ever wondered why crypto has not become mainstream in the last 30 years? That's why. 'nuff said.

Instead of using width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:

• 0 = don't grow (shorthand for flex-grow)
• 0 = don't shrink (shorthand for flex-shrink)
• 230px = start at 230px (shorthand for flex-basis)

which means: always be 230px.

See fiddle, thanks @TylerH

Oh, and you don't need the justify-content and align-items here.

img {
    max-width: 100%;
}
#container {
    display: flex;
    x-justify-content: space-around;
    x-align-items: stretch;
    max-width: 1200px;
}
.column.left {
    width: 230px;
    flex: 0 0 230px;
}
.column.right {
    width: 230px;
    flex: 0 0 230px;
    border-left: 1px solid #eee;
}
.column.center {
    border-left: 1px solid #eee;
}

You have to switch it!

switch (true) {
    case ( (pageid === "listing-page") || (pageid === ("home-page") ):
        alert("hello");
        break;
    case (pageid === "details-page"):
        alert("goodbye");
        break;
}

From the selectors specification:

Attribute values must be CSS identifiers or strings.

Identifiers cannot start with a number. Strings must be quoted.

1 is therefore neither a valid identifier nor a string.

Use "1" (which is a string) instead.

var a = document.querySelector('a[data-a="1"]');

Seems like you expected the query to return running totals, but it must have given you the same values for both partitions of AccountID.

To obtain running totals with SUM() OVER (), you need to add an ORDER BY sub-clause after PARTITION BY …, like this:

SUM(Quantity) OVER (PARTITION BY AccountID ORDER BY ID)

But remember, not all database systems support ORDER BY in the OVER clause of a window aggregate function. (For instance, SQL Server didn't support it until the latest version, SQL Server 2012.)

It comes down to whether the feature is used by one person or if others are working off of it.

You can force the push after the rebase if it's just you:

git push origin feature -f

However, if others are working on it, you should merge and not rebase off of master.

git merge master
git push origin feature

This will ensure that you have a common history with the people you are collaborating with.

On a different level, you should not be doing back-merges. What you are doing is polluting your feature branch's history with other commits that don't belong to the feature, making subsequent work with that branch more difficult - rebasing or not.

This is my article on the subject called branch per feature.

Hope this helps.

Use \r instead of \n.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.

TEXT VIEW DELEGATE METHODS

Use these two delegate methods and also write UITextViewDelegate in your class

func textViewDidBeginEditing(_ textView: UITextView) {
    if (commentsTextView.text == "Type Your Comments")
    {
        commentsTextView.text = nil
        commentsTextView.textColor = UIColor.darkGray
    }
}

func textViewDidEndEditing(_ textView: UITextView) {
    if commentsTextView.text.isEmpty
    {
        commentsTextView.text = "Type Your Comments"
        commentsTextView.textColor = UIColor.darkGray
    }
    textView.resignFirstResponder()
}

I had the same issue and found out that my code was using the injection before it was initialized.

services.AddControllers(); // Will cause a problem if you use your IBloggerRepository in there since it's defined after this line.
services.AddScoped<IBloggerRepository, BloggerRepository>();

I know it has nothing to do with the question, but since I was sent to this page, I figure out it my be useful to someone else.

You can also "center" the text with:

vertical-align: middle;

The closest option available is

[\u\l]+

which matches a sequence of uppercase and lowercase letters. However, it is not supported by all editors/languages, so it is probably safer to use

[a-zA-Z]+

as other users suggest
