Programs & Examples On #Tscrollbox

your button xml:

 <Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="jump to activity b"
    />

Mainactivity.java:

 Button btn=findViewVyId(R.id.btn);
btn.setOnClickListener(btnclick);
btnclick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
               Intent intent=new Intent();
                intent.setClass(Mainactivity.this,b.class);
                startActivity(intent);
    }
});

I used this question as a starting point for my own solution. Thought it was appropriate to contribute my code back since its smaller than tabacitu's

Dependencies:

• underscore.js
• https://github.com/estebanav/javascript-mobile-desktop-geolocation
• <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>

Code:

if(geoPosition.init()){  

    var foundLocation = function(city, state, country, lat, lon){
        //do stuff with your location! any of the first 3 args may be null
        console.log(arguments);
    }

    var geocoder = new google.maps.Geocoder(); 
    geoPosition.getCurrentPosition(function(r){
        var findResult = function(results, name){
            var result =  _.find(results, function(obj){
                return obj.types[0] == name && obj.types[1] == "political";
            });
            return result ? result.short_name : null;
        };

Despite other answers here, you should not use display:none to hide the label element.

The accessible way to hide a label visually is to use an 'off-left' or 'clip' rule in your CSS. Using display:none will prevent people who use screen-readers from having access to the content of the label element. Using display:none hides content from all users, and that includes screen-reader users (who benefit most from label elements).

label[for="foo"] { 
    border: 0;
    clip: rect(0 0 0 0);
    height: 1px;
    margin: -1px;
    overflow: hidden;
    padding: 0;
    position: absolute;
    width: 1px;
}

The W3C and WAI offer more guidance on this topic, including CSS for the 'clip' technique.

@last-child's answer is a great answer!

However, adding a border to my H2 produced an underline longer than the text.

If you're dynamically writing your CSS, or if like me you're lucky and know what the text will be, you can do the following:

1. change the content to something the right length (ie the same

2. text) set the font color to transparent (or rgba(0,0,0,0) )

to underline <h2>Processing</h2> (for example), change last-child's code to be:

a {
    text-decoration: none;
    position: relative;
}
a:after {
    content: 'Processing';
    color: transparent;

    width: 100%;
    position: absolute;
    left: 0;
    bottom: 1px;

    border-width: 0 0 1px;
    border-style: solid;
}

I think we do not accept long structure programming we will add everytime shot code see below answer.

<input type="text" oninput="this.value = this.value.replace(/[^0-9.]/g, ''); this.value = this.value.replace(/(\..*)\./g, '$1');" >

Use NSURLComponents to build your NSURL like this

var urlComponents = NSURLComponents(string: "https://www.google.de/maps/")!

urlComponents.queryItems = [
  NSURLQueryItem(name: "q", value: String(51.500833)+","+String(-0.141944)),
  NSURLQueryItem(name: "z", value: String(6))
]
urlComponents.URL // returns https://www.google.de/maps/?q=51.500833,-0.141944&z=6

font: https://www.ralfebert.de/snippets/ios/encoding-nsurl-get-parameters/

you can keep your withdraw and deposit methods static if you want however you'd have to write it like the code below. sb = starting balance and eB = ending balance.

Account account = new Account(1122, 20000, 4.5);

    double sB = Account.withdraw(account.getBalance(), 2500);
    double eB = Account.deposit(sB, 3000);
    System.out.println("Balance is " + eB);
    System.out.println("Monthly interest is " + (account.getAnnualInterestRate()/12));
    account.setDateCreated(new Date());
    System.out.println("The account was created " + account.getDateCreated());

Install mysysgit. (Same as Greg Hewgill's answer.)

Install Tortoisegit. (Tortoisegit requires mysysgit or something similiar like Cygwin.)

After TortoiseGit is installed, right-click on a folder, select Git Clone..., then enter the Url of the repository, then click Ok.

This answer is not any better than just installing mysysgit, but you can avoid the dreaded command line. :)

No, you can just write the function as:

$(document).ready(function() {
    MyBlah("hello");
});

function MyBlah(blah) {
    alert(blah);
}

This calls the function MyBlah on content ready.

Do it in the controller ( controller as syntax below)

controller:

vm.question= {};
vm.question.active = true;

form

<input ng-model="vm.question.active" type="checkbox" id="active" name="active">

Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.

And the verification can be easily made with the following script contained in the blog post before:

DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)

jQuery also offers an $.isArray() method:

var a = ["A", "AA", "AAA"];_x000D_
_x000D_
if($.isArray(a)) {_x000D_
  alert("a is an array!");_x000D_
} else {_x000D_
  alert("a is not an array!");_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I don't think it's "bad" idea to find out who is the view controller for some cases. What could be a bad idea is to save the reference to this controller as it could change just as superviews change. In my case I have a getter that traverses the responder chain.

//.h

@property (nonatomic, readonly) UIViewController * viewController;

//.m

- (UIViewController *)viewController
{
    for (UIResponder * nextResponder = self.nextResponder;
         nextResponder;
         nextResponder = nextResponder.nextResponder)
    {
        if ([nextResponder isKindOfClass:[UIViewController class]])
            return (UIViewController *)nextResponder;
    }

    // Not found
    NSLog(@"%@ doesn't seem to have a viewController". self);
    return nil;
}

This can actually be done in CSS and very minimal JS just by adding a CSS class (don't set styles directly in JS!) with e.g. a ng-clickevent. The principle is that one can't animate height: 0; to height: auto; but this can be tricked by animating the max-height property. The container will expand to it's "auto-height" value when .foo-open is set - no need for fixed height or positioning.

.foo {
    max-height: 0;
}

.foo--open {
    max-height: 1000px; /* some arbitrary big value */
    transition: ...
}

see this fiddle by the excellent Lea Verou

As a concern raised in the comments, note that while this animation works perfectly with linear easing, any exponential easing will produce a behaviour different from what could be expected - due to the fact that the animated property is max-height and not height itself; specifically, only the height fraction of the easing curve of max-height will be displayed.

I was using a KEY word for one of my columns and I solved it with brackets []

I would argue against using SqlDataReader here; ADO.NET has lots of edge cases and complications, and in my experience most manually written ADO.NET code is broken in at least one way (usually subtle and contextual).

Tools exist to avoid this. For example, in the case here you want to read a column of strings. Dapper makes that completely painless:

var region = ... // some filter
var vals = connection.Query<string>(
    "select Name from Table where Region=@region", // query
    new { region } // parameters
).AsList();

Dapper here is dealing with all the parameterization, execution, and row processing - and a lot of other grungy details of ADO.NET. The <string> can be replaced with <SomeType> to materialize entire rows into objects.

Attributed String Programming Guide:

UIFont *font = [UIFont fontWithName:@"Palatino-Roman" size:14.0];
NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font
                                forKey:NSFontAttributeName];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"strigil" attributes:attrsDictionary];

Update: I tried to use addAttribute: method in my own app, but it seemed to be not working on the iOS 6 Simulator:

NSLog(@"%@", textView.attributedText);

The log seems to show correctly added attributes, but the view on iOS simulator was not display with attributes.

This code worked for me

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<UserDetail>()
            .HasRequired(d => d.User)
            .WithOptional(u => u.UserDetail)
            .WillCascadeOnDelete(true);
    }

The migration code was:

public override void Up()
    {
        AddForeignKey("UserDetail", "UserId", "User", "UserId", cascadeDelete: true);
    }

And it worked fine. When I first used

modelBuilder.Entity<User>()
    .HasOptional(a => a.UserDetail)
    .WithOptionalDependent()
    .WillCascadeOnDelete(true);

The migration code was:

AddForeignKey("User", "UserDetail_UserId", "UserDetail", "UserId", cascadeDelete: true); 

but it does not match any of the two overloads available (in EntityFramework 6)

Here's my quick and dirty version, basically its splitting up the URL parameters separated by '&' into array elements, and then iterates over that array adding key/value pairs separated by '=' into an object. I'm using decodeURIComponent() to translate the encoded characters to their normal string equivalents (so %20 becomes a space, %26 becomes '&', etc):

function deparam(paramStr) {
    let paramArr = paramStr.split('&');     
    let paramObj = {};
    paramArr.forEach(e=>{
        let param = e.split('=');
        paramObj[param[0]] = decodeURIComponent(param[1]);
    });
    return paramObj;
}

example:

deparam('abc=foo&def=%5Basf%5D&xyz=5')

returns

{
    abc: "foo"
    def:"[asf]"
    xyz :"5"
}

The only issue is that xyz is a string and not a number (due to using decodeURIComponent()), but beyond that its not a bad starting point.

Status 2018:

There seems to be no way to place buttons (drawings, images) within cells in a way that would allow them to be linked to Apps Script functions.

This being said, there are some things that you can indeed do:

You can...

You can place images within cells using IMAGE(URL), but they cannot be linked to Apps Script functions.

You can place images within cells and link them to URLs using:
=HYPERLINK("http://example.com"; IMAGE("http://example.com/myimage.png"; 1))

You can create drawings as described in the answer of @Eduardo and they can be linked to Apps Script functions, but they will be stand-alone items that float freely "above" the spreadsheet and cannot be positioned in cells. They cannot be copied from cell to cell and they do not have a row or col position that the script function could read.

Use the following to evaluate an expression (constant 0 evaluates to false).

#if 0
 ...
#endif

I had some decrypted byte arrays with padding characters and other stuff I didn't need, so I did this (probably not perfect, but it works for my limited use)

var junk = String.fromCharCode.apply(null, res).split('').map(char => char.charCodeAt(0) <= 127 && char.charCodeAt(0) >= 32 ? char : '').join('');

I have searched long and hard for an answer to this question. From what I gather Google did that on purpose once people used the internet connection to add spam comments to the market. However, I did find a guy who had done it and was willing to share the required images. The linked AVD runs(for me) both the market and browser internet.

NOTE: It looks like it's just going to fix the market. But the market won't run without internet, so if the market is fixed, the browser internet will work too. I downloaded the linked files myself and it showed the internet in the browser perfectly.

Every time I go from heavy C++ coding to Java, it takes me a little while to adapt to the lack of const-correctness in Java. This usage of const in C++ is much different than just declaring constant variables, if you didn't know. Essentially, it ensures that an object is immutable when accessed through a special kind of pointer called a const-pointer When in Java, in places where I'd normally want to return a const-pointer, I instead return a reference with an interface type containing only methods that shouldn't have side effects. Unfortunately, this isn't enforced by the langauge.

Wikipedia offers the following information on the subject:

Interestingly, the Java language specification regards const as a reserved keyword — i.e., one that cannot be used as variable identifier — but assigns no semantics to it. It is thought that the reservation of the keyword occurred to allow for an extension of the Java language to include C++-style const methods and pointer to const type. The enhancement request ticket in the Java Community Process for implementing const correctness in Java was closed in 2005, implying that const correctness will probably never find its way into the official Java specification.

You could use Brushes.White to set the foreground.

myTextBlock.Foreground = Brushes.White;

The Brushes class is located in System.Windows.Media namespace.

Or, you can press Ctrl+. while the cursor is on the unknown class name to automatically add using directive.

The easiest way is to use lubridate:

library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)

This function automatically returns objects of class POSIXct and will work with either factors or characters.

I found this much simpler. Simply type this into the terminal:

PATH=$PATH:C:\[pythondir]\scripts 

I would like to expand the answers to whoever might be using this in a bigger project, you could accidentally attach multiple event handlers and the program would behave weirdly.

To get rid of that, I used a singleton function exposed by a factory, from which you would call inactivityTimeoutFactory.switchTimeoutOn() and inactivityTimeoutFactory.switchTimeoutOff() in your angular application to respectively activate and deactivate the logout due to inactivity functionality.

This way you make sure you are only running a single instance of the event handlers, no matter how many times you try to activate the timeout procedure, making it easier to use in applications where the user might login from different routes.

Here is my code:

'use strict';

angular.module('YOURMODULENAME')
  .factory('inactivityTimeoutFactory', inactivityTimeoutFactory);

inactivityTimeoutFactory.$inject = ['$document', '$timeout', '$state'];

function inactivityTimeoutFactory($document, $timeout, $state)  {
  function InactivityTimeout () {
    // singleton
    if (InactivityTimeout.prototype._singletonInstance) {
      return InactivityTimeout.prototype._singletonInstance;
    }
    InactivityTimeout.prototype._singletonInstance = this;

    // Timeout timer value
    const timeToLogoutMs = 15*1000*60; //15 minutes
    const timeToWarnMs = 13*1000*60; //13 minutes

    // variables
    let warningTimer;
    let timeoutTimer;
    let isRunning;

    function switchOn () {
      if (!isRunning) {
        switchEventHandlers("on");
        startTimeout();
        isRunning = true;
      }
    }

    function switchOff()  {
      switchEventHandlers("off");
      cancelTimersAndCloseMessages();
      isRunning = false;
    }

    function resetTimeout() {
      cancelTimersAndCloseMessages();
      // reset timeout threads
      startTimeout();
    }

    function cancelTimersAndCloseMessages () {
      // stop any pending timeout
      $timeout.cancel(timeoutTimer);
      $timeout.cancel(warningTimer);
      // remember to close any messages
    }

    function startTimeout () {
      warningTimer = $timeout(processWarning, timeToWarnMs);
      timeoutTimer = $timeout(processLogout, timeToLogoutMs);
    }

    function processWarning() {
      // show warning using popup modules, toasters etc...
    }

    function processLogout() {
      // go to logout page. The state might differ from project to project
      $state.go('authentication.logout');
    }

    function switchEventHandlers(toNewStatus) {
      const body = angular.element($document);
      const trackedEventsList = [
        'keydown',
        'keyup',
        'click',
        'mousemove',
        'DOMMouseScroll',
        'mousewheel',
        'mousedown',
        'touchstart',
        'touchmove',
        'scroll',
        'focus'
      ];

      trackedEventsList.forEach((eventName) => {
        if (toNewStatus === 'off') {
          body.off(eventName, resetTimeout);
        } else if (toNewStatus === 'on') {
          body.on(eventName, resetTimeout);
        }
      });
    }

    // expose switch methods
    this.switchOff = switchOff;
    this.switchOn = switchOn;
  }

  return {
    switchTimeoutOn () {
      (new InactivityTimeout()).switchOn();
    },
    switchTimeoutOff () {
      (new InactivityTimeout()).switchOff();
    }
  };

}

I used Matchers.refEq for this.

To complement the preexisting, helpful answers with guidance of when to use which approach and a performance comparison.

• Outside of a pipeline^[1], use (PSv3+):

  $objects.Name

  as demonstrated in rageandqq's answer, which is both syntactically simpler and much faster.

  • Accessing a property at the collection level to get its members' values as an array is called member enumeration and is a PSv3+ feature.

  • Alternatively, in PSv2, use the foreach statement, whose output you can also assign directly to a variable:

    $results = foreach ($obj in $objects) { $obj.Name }

  • If collecting all output from a (pipeline) command in memory first is feasible, you can also combine pipelines with member enumeration; e.g.:

     (Get-ChildItem -File | Where-Object Length -lt 1gb).Name
    

  • Tradeoffs:

    • Both the input collection and output array must fit into memory as a whole.
    • If the input collection is itself the result of a command (pipeline) (e.g., (Get-ChildItem).Name), that command must first run to completion before the resulting array's elements can be accessed.

• In a pipeline, in case you must pass the results to another command, notably if the original input doesn't fit into memory as a whole, use:

  $objects | Select-Object -ExpandProperty Name

  • The need for -ExpandProperty is explained in Scott Saad's answer (you need it to get only the property value).
  • You get the usual pipeline benefits of the pipeline's streaming behavior, i.e. one-by-one object processing, which typically produces output right away and keeps memory use constant (unless you ultimately collect the results in memory anyway).
  • Tradeoff:
    • Use of the pipeline is comparatively slow.

For small input collections (arrays), you probably won't notice the difference, and, especially on the command line, sometimes being able to type the command easily is more important.

Here is an easy-to-type alternative, which, however is the slowest approach; it uses simplified ForEach-Object syntax called an operation statement (again, PSv3+): ; e.g., the following PSv3+ solution is easy to append to an existing command:

$objects | % Name      # short for: $objects | ForEach-Object -Process { $_.Name }

The PSv4+ .ForEach() array method, more comprehensively discussed in this article, is yet another, well-performing alternative, but note that it requires collecting all input in memory first, just like member enumeration:

# By property name (string):
$objects.ForEach('Name')

# By script block (more flexibility; like ForEach-Object)
$objects.ForEach({ $_.Name })

• This approach is similar to member enumeration, with the same tradeoffs, except that pipeline logic is not applied; it is marginally slower than member enumeration, though still noticeably faster than the pipeline.

• For extracting a single property value by name (string argument), this solution is on par with member enumeration (though the latter is syntactically simpler).

• The script-block variant ({ ... }) allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).

Note: The .ForEach() array method, like its .Where() sibling (the in-memory equivalent of Where-Object), always returns a collection (an instance of [System.Collections.ObjectModel.Collection[psobject]]), even if only one output object is produced.
By contrast, member enumeration, Select-Object, ForEach-Object and Where-Object return a single output object as-is, without wrapping it in a collection (array).

Comparing the performance of the various approaches

Here are sample timings for the various approaches, based on an input collection of 10,000 objects, averaged across 10 runs; the absolute numbers aren't important and vary based on many factors, but it should give you a sense of relative performance (the timings come from a single-core Windows 10 VM:

Important

• The relative performance varies based on whether the input objects are instances of regular .NET Types (e.g., as output by Get-ChildItem) or [pscustomobject] instances (e.g., as output by Convert-FromCsv).
  The reason is that [pscustomobject] properties are dynamically managed by PowerShell, and it can access them more quickly than the regular properties of a (statically defined) regular .NET type. Both scenarios are covered below.

• The tests use already-in-memory-in-full collections as input, so as to focus on the pure property extraction performance. With a streaming cmdlet / function call as the input, performance differences will generally be much less pronounced, as the time spent inside that call may account for the majority of the time spent.

• For brevity, alias % is used for the ForEach-Object cmdlet.

General conclusions, applicable to both regular .NET type and [pscustomobject] input:

• The member-enumeration ($collection.Name) and foreach ($obj in $collection) solutions are by far the fastest, by a factor of 10 or more faster than the fastest pipeline-based solution.

• Surprisingly, % Name performs much worse than % { $_.Name } - see this GitHub issue.

• PowerShell Core consistently outperforms Windows Powershell here.

Conclusions:

• Note how with [pscustomobject] input .ForEach('Name') by far outperforms the script-block based variant, .ForEach({ $_.Name }).

• Similarly, [pscustomobject] input makes the pipeline-based Select-Object -ExpandProperty Name faster, in Windows PowerShell virtually on par with .ForEach({ $_.Name }), but in PowerShell Core still about 50% slower.

• In short: With the odd exception of % Name, with [pscustomobject] the string-based methods of referencing the properties outperform the scriptblock-based ones.

# Set this to $true to test with [pscustomobject] instances below.
$useCustomObjectInput = $false

# Create sample input objects.
if ($useCustomObjectInput) {
  # Use [pscustomobject] instances.
  $objects = 1..$count | % { [pscustomobject] @{ Name = "$foobar_$_"; Other1 = 1; Other2 = 2; Other3 = 3; Other4 = 4 } }

My problem was that wampmysqld64 service was disabled, so I went to: task manager > services > right click on wampmysqld64 and then properties, another window is gonna open, look for wampmysqld64 service then right click and then click on properties and a window is gonna pop up:

On "Startup type" just change it from disabled to automatic, then go back click on the service and run it and that's it wamp logo it's gonna turn green.

Since many of the fancy solutions above don't work with UWP and because I love Linq and functional approaches I pressent you my version to this problem. To escape the comparison when the first difference occures, I chose .FirstOrDefault()

public static bool CompareByteArrays(byte[] ba0, byte[] ba1) =>
    !(ba0.Length != ba1.Length || Enumerable.Range(1,ba0.Length)
        .FirstOrDefault(n => ba0[n] != ba1[n]) > 0);

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

Live Sample

Probably your item.photo is undefined if you don't have a photo attribute on item in the first place and thus undefined != ''. But if you'd put some code to show how you provide values to item, it would help.

PS: Sorry to post this as an answer (I rather think it's more of a comment), but I don't have enough reputation yet.

If -prune doesn't work for you, this will:

find -name "*.js" -not -path "./directory/*"

Caveat: requires traversing all of the unwanted directories.

!!! KIVY !!!

I was amazed seeing that no one mentioned Kivy!!!

I have once done a project using Tkinter, although they do advocate that it has improved a lot, it still gives me a feel of windows 98, so I switched to Kivy.

I have been following a tutorial series if it helps...

Just to give an idea of how kivy looks, see this (The project I am working on):

And I have been working on it for barely a week now ! The benefits for Kivy you ask? Check this

The reason why I chose this is, its look and that it can be used in mobile as well.

This isn't really briefer but might be a more flexible way (credit):

FOR /F "TOKENS=1* DELIMS= " %%A IN ('DATE/T') DO SET CDATE=%%B
FOR /F "TOKENS=1,2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=1,2 DELIMS=/ eol=/" %%A IN ('echo %CDATE%') DO SET dd=%%B
FOR /F "TOKENS=2,3 DELIMS=/ " %%A IN ('echo %CDATE%') DO SET yyyy=%%B
SET date=%mm%%dd%%yyyy%

1. Go to Control Panel -> Programs -> Programs and features

   

2. Go to Windows Features and disable Internet Explorer 11

   

   

3. Then click on Display installed updates

   

4. Search for Internet explorer

5. Right-click on Internet Explorer 11 -> Uninstall

   

6. Do the same with Internet Explorer 10

7. Restart your computer
8. Install Internet Explorer 10 here (old broken link)

I think it will be okay.

I use it and I'm happy with it, as I have to type much less to make a new header. It worked fine for me in three platforms: Windows, Mac and Linux.

I don't have any performance information but I believe that the difference between #pragma and the include guard will be nothing comparing to the slowness of parsing the C++ grammar. That's the real problem. Try to compile the same number of files and lines with a C# compiler for example, to see the difference.

In the end, using the guard or the pragma, won't matter at all.

Interesting question! While there are plenty of guides on horizontally and vertically centering a div, an authoritative treatment of the subject where the centered div is of an unpredetermined width is conspicuously absent.

Let's apply some basic constraints:

• No Javascript
• No mangling of the display property to table-cell, which is of questionable support status

Given this, my entry into the fray is the use of the inline-block display property to horizontally center the span within an absolutely positioned div of predetermined height, vertically centered within the parent container in the traditional top: 50%; margin-top: -123px fashion.

Markup: div > div > span

CSS:

body > div { position: relative; height: XYZ; width: XYZ; }
div > div { 
  position: absolute;
  top: 50%;
  height: 30px;
  margin-top: -15px; 
  text-align: center;}
div > span { display: inline-block; }

Source: http://jsfiddle.net/38EFb/

An alternate solution that doesn't require extraneous markups but that very likely produces more problems than it solves is to use the line-height property. Don't do this. But it is included here as an academic note: http://jsfiddle.net/gucwW/

For those who are having trouble indenting phpstorm here I have a tip and I hope they help ...

First you have to go to file-> settings-> keymap-> select-> windows.

If they are on the windows machine. If you are on mac and choose macos.

This is how I did it, I hope it brings a new perspective how this works on Swift.

In this example below I will get the any string between []

var sample = "this is an [hello] amazing [world]"

var regex = NSRegularExpression(pattern: "\\[.+?\\]"
, options: NSRegularExpressionOptions.CaseInsensitive 
, error: nil)

var matches = regex?.matchesInString(sample, options: nil
, range: NSMakeRange(0, countElements(sample))) as Array<NSTextCheckingResult>

for match in matches {
   let r = (sample as NSString).substringWithRange(match.range)//cast to NSString is required to match range format.
    println("found= \(r)")
}

How about

DROP USER <username>

This is actually an alias for DROP ROLE.

You have to explicity drop any privileges associated with that user, also to move its ownership to other roles (or drop the object).

This is best achieved by

REASSIGN OWNED BY <olduser> TO <newuser>

and

DROP OWNED BY <olduser>

The latter will remove any privileges granted to the user.

See the postgres docs for DROP ROLE and the more detailed description of this.

Addition:

Apparently, trying to drop a user by using the commands mentioned here will only work if you are executing them while being connected to the same database that the original GRANTS were made from, as discussed here:

https://www.postgresql.org/message-id/83894A1821034948BA27FE4DAA47427928F7C29922%40apde03.APD.Satcom.Local

You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.

If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-

First copy the table

CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;

Then drop columns that you want to be after the column you will insert

ALTER TABLE my_tab DROP COLUMN three;

Now add the new column (two in this example) and the ones you removed.

ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));

Lastly add back the data for the re-created columns

UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);

Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?

div.test td, div.test caption, div.test th 

works for me.

The child selector > does not work in IE6.

You can use this configuration:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library

openFile
-vmargs
-Xms512m
-Xmx1024m
-XX:+UseParallelGC
-XX:PermSize=256M
-XX:MaxPermSize=512M

For the filestream:

//Check if the directory exists
if (!System.IO.Directory.Exists(@"C:\yourDirectory"))
{
    System.IO.Directory.CreateDirectory(@"C:\yourDirectory");
}

//Write the file
using (System.IO.StreamWriter outfile = new System.IO.StreamWriter(@"C:\yourDirectory\yourFile.txt"))
{
    outfile.Write(yourFileAsString);
}

Warnings are annoying. As mentioned in other answers, you can suppress them using:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

But if you want to handle them one by one and you are managing a bigger codebase, it will be difficult to find the line of code which is causing the warning. Since warnings unlike errors don't come with code traceback. In order to trace warnings like errors, you can write this at the top of the code:

import warnings
warnings.filterwarnings("error")

But if the codebase is bigger and it is importing bunch of other libraries/packages, then all sort of warnings will start to be raised as errors. In order to raise only certain type of warnings (in your case, its FutureWarning) as error, you can write:

import warnings
warnings.simplefilter(action='error', category=FutureWarning)

All you need to do is set "jquery": true in your .jshintrc.

Per the JSHint options reference:

jquery

This option defines globals exposed by the jQuery JavaScript library.

Try this, works for me: ls -d /a/b/c/*

You don't want to lose the user scaling option if you can help it. I like this JS solution from here.

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

    var addEvent = 'addEventListener',
        type = 'gesturestart',
        qsa = 'querySelectorAll',
        scales = [1, 1],
        meta = qsa in doc ? doc[qsa]('meta[name=viewport]') : [];

    function fix() {
        meta.content = 'width=device-width,minimum-scale=' + scales[0] + ',maximum-scale=' + scales[1];
        doc.removeEventListener(type, fix, true);
    }

    if ((meta = meta[meta.length - 1]) && addEvent in doc) {
        fix();
        scales = [.25, 1.6];
        doc[addEvent](type, fix, true);
    }

}(document));
</script>

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Various forms depending on type of List, for Array List:

val myList = mutableListOf<Kolory>() 
// or more specifically use the helper for a specific list type
val myList = arrayListOf<Kolory>()

For LinkedList:

val myList = linkedListOf<Kolory>()
// same as
val myList: MutableList<Kolory> = linkedListOf()

For other list types, will be assumed Mutable if you construct them directly:

val myList = ArrayList<Kolory>()
// or
val myList = LinkedList<Kolory>()

This holds true for anything implementing the List interface (i.e. other collections libraries).

No need to repeat the type on the left side if the list is already Mutable. Or only if you want to treat them as read-only, for example:

val myList: List<Kolory> = ArrayList()

It seems i came late to the party, but you should better check this out too.

So in system.web for caching up exceptions within the application such as return HttpNotFound()

  <system.web>
    <customErrors mode="RemoteOnly">
      <error statusCode="404" redirect="/page-not-found" />
      <error statusCode="500" redirect="/internal-server-error" />
    </customErrors>
  </system.web>

and in system.webServer for catching up errors that were caught by IIS and did not made their way to the asp.net framework

 <system.webServer>
    <httpErrors errorMode="DetailedLocalOnly">
      <remove statusCode="404"/>
      <error statusCode="404" path="/page-not-found" responseMode="Redirect"/>
      <remove statusCode="500"/>
      <error statusCode="500" path="/internal-server-error" responseMode="Redirect"/>
  </system.webServer>

In the last one if you worry about the client response then change the responseMode="Redirect" to responseMode="File" and serve a static html file, since this one will display a friendly page with an 200 response code.

I wanted to add an updated answer here since (somewhat) recent updates to the JDK have made it a bit easier to read the contents of an HTTP URL. Like others have said, you'll still need to use a JSON library to do the parsing, since the JDK doesn't currently contain one. Here are a few of the most commonly used JSON libraries for Java:

• org.JSON
• FasterXML Jackson
• GSON

To retrieve JSON from a URL, this seems to be the simplest way using strictly JDK classes (but probably not something you'd want to do for large payloads), Java 9 introduced: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/io/InputStream.html#readAllBytes()

try(java.io.InputStream is = new java.net.URL("https://graph.facebook.com/me").openStream()) {
    String contents = new String(is.readAllBytes());
}

To parse the JSON using the GSON library, for example

com.google.gson.JsonElement element = com.google.gson.JsonParser.parseString(contents); //from 'com.google.code.gson:gson:2.8.6'

The previously linked solution is a horrible piece of code; nearly every line contains a bug. Use fgetcsv instead:

<?php
echo "<html><body><table>\n\n";
$f = fopen("so-csv.csv", "r");
while (($line = fgetcsv($f)) !== false) {
        echo "<tr>";
        foreach ($line as $cell) {
                echo "<td>" . htmlspecialchars($cell) . "</td>";
        }
        echo "</tr>\n";
}
fclose($f);
echo "\n</table></body></html>";

In Jenkins 2.138.3 there are two different types of pipelines.

Declarative and Scripted pipelines.

"Declarative pipelines is a new extension of the pipeline DSL (it is basically a pipeline script with only one step, a pipeline step with arguments (called directives), these directives should follow a specific syntax. The point of this new format is that it is more strict and therefore should be easier for those new to pipelines, allow for graphical editing and much more. scripted pipelines is the fallback for advanced requirements."

jenkins pipeline: agent vs node?

Here is an example of using environment and global variables in a Declarative Pipeline. From what I can tell enviroment are static after they are set.

def  browser = 'Unknown'

pipeline {
    agent any
    environment {
    //Use Pipeline Utility Steps plugin to read information from pom.xml into env variables
    IMAGE = readMavenPom().getArtifactId()
    VERSION = readMavenPom().getVersion()


    }
    stages {
        stage('Example') {
            steps {
                script {
                    browser = sh(returnStdout: true, script: 'echo Chrome')
                }
            }
        }
        stage('SNAPSHOT') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("PROD") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {
                    echo "SNAPSHOT"
                    echo "${browser}"
                }
            }
            stage('RELEASE') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("TEST") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {

What worked for me... It seems if you install (or a dependent package installs) Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package it makes some web.config transforms that allow you to use C#7.x features in ASP.NET Razor pages. Whilst I found these worked fine on my local machine they didn't work on our server (even when the compiler was in the /bin/ folder).

The solution was to locate the element below and remove completely from web.config

  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
  </system.codedom>

You should use LoadXml method, not Load:

xmlDoc.LoadXml(myXML); 

Load method is trying to load xml from a file and LoadXml from a string. You could also use XPath:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);

string xpath = "myDataz/listS/sog";
var nodes = xmlDoc.SelectNodes(xpath);

foreach (XmlNode childrenNode in nodes)
{
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("//field1").Value);
} 

In a new PHP7 there is a finally a support for a cryptographically secure pseudo-random integers.

int random_int ( int $min , int $max )

random_int — Generates cryptographically secure pseudo-random integers

which basically makes previous answers obsolete.

How was the database exported?

• If it was exported using exp and a full schema was exported, then

  1. Create the user:

     create user <username> identified by <password> default tablespace <tablespacename> quota unlimited on <tablespacename>;
     

  2. Grant the rights:

     grant connect, create session, imp_full_database to <username>;
     

  3. Start the import with imp:

     imp <username>/<password>@<hostname> file=<filename>.dmp log=<filename>.log full=y;
     

• If it was exported using expdp, then start the import with impdp:

  impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;
  

Looking at the error log, it seems you have not specified the directory, so Oracle tries to find the dmp file in the default directory (i.e., E:\app\Vensi\admin\oratest\dpdump\).

Either move the export file to the above path or create a directory object to pointing to the path where the dmp file is present and pass the object name to the impdp command above.

You can use valgrind to debug it.

Check out the blog on using Valgrind Link

I have the same issue with windows10, apache 2.2.25, php 5.2 Im trying to add GD to a working PHP.

how I turn around and change between forward and backward slash, plus trailing or not, I get some variant of ;

PHP Warning: PHP Startup: Unable to load dynamic library 'C:/php\php_gd2.dll' - Det g\xe5r inte att hitta den angivna modulen.\r\n in Unknown on line 0

(swedish translated: 'It is not possible to find the module' )

in this perticular case, the php.ini was: extension_dir = "C:/php"

the dll is put in two places C:\php and C:\php\ext

IS it possible that there is and "error" in the error log entry ? I.e. that the .dll IS found (as a file) but not of the right format, or something like that ??

To add the contents of one list to another list which already exists, you can use:

targetList.AddRange(sourceList);

If you're just wanting to create a new copy of the list, see Lasse's answer.

Late answer but finger also shows more information on user

  sudo apt-get finger 
  finger "$username"

The Catch is Capture all SQL run between two points in time. Like the way SQL Server also does.

There are situations where it is useful to capture the SQL that a particular user is running in the database. Usually you would simply enable session tracing for that user, but there are two potential problems with that approach.

1. The first is that many web based applications maintain a pool of persistent database connections which are shared amongst multiple users.
2. The second is that some applications connect, run some SQL and disconnect very quickly, making it tricky to enable session tracing at all (you could of course use a logon trigger to enable session tracing in this case).

A quick and dirty solution to the problem is to capture all SQL statements that are run between two points in time.

The following procedure will create two tables, each containing a snapshot of the database at a particular point. The tables will then be queried to produce a list of all SQL run during that period.

If possible, you should do this on a quiet development system - otherwise you risk getting way too much data back.

1. Take the first snapshot Run the following sql to create the first snapshot:

   create table sql_exec_before as
   select executions,hash_value
   from v$sqlarea
   /
   

2. Get the user to perform their task within the application.

3. Take the second snapshot.

   create table sql_exec_after as
   select executions, hash_value
   from v$sqlarea
   /
   

4. Check the results Now that you have captured the SQL it is time to query the results.

This first query will list all query hashes that have been executed:

select  aft.hash_value
from sql_exec_after aft
left outer join sql_exec_before bef
  on aft.hash_value  =  bef.hash_value 
where aft.executions > bef.executions
   or bef.executions is null;
/

This one will display the hash and the SQL itself: set pages 999 lines 100 break on hash_value

select  hash_value, sql_text
from    v$sqltext
where   hash_value in (
    select  aft.hash_value
    from sql_exec_after aft
    left outer join sql_exec_before bef
      on aft.hash_value  =  bef.hash_value
    where aft.executions > bef.executions
       or bef.executions is null;
)
order by
    hash_value, piece
/

5. Tidy up Don't forget to remove the snapshot tables once you've finished:

drop table sql_exec_before
/

drop table sql_exec_after
/

my_list = sorted(dict.items(), key=lambda x: x[1])

Here we have same question. You can use the following code:

SqlConnection con = new SqlConnection();
con.ConnectionString = ConfigurationManager.ConnectionStrings["yourconnectionstringnamehere"].ConnectionString;
con.Open();
SqlCommand com = new SqlCommand();
com.Connection = con;
com.CommandText = "DELETE FROM [tablenamehere]";
SqlDataReader data = com.ExecuteReader();
con.Close();

But before you need to import following code to your project:

using System.Configuration;
using System.Data.SqlClient;

This is the specific part of the code that can delete all rows is a table:

DELETE FROM [tablenamehere]

This must be your table name:tablenamehere - This can delete all rows in table: DELETE FROM

How about add this to your xaml:

<Separator/>

FOR FADE add this first line with your animation's object.

.animate().alpha(1).setDuration(2000);

FOR EXAMPLE

There are at least these two issues I have observed for this problem: 1) It could be either because your sender username or password might not be correct 2) Or it could be as answered by Avinash above, the security condition on the account. Once you try SendMail using SMTP, you normally get a notification in to your account that it may be an unauthorized attempt to access your account, if not user can follow the link to turn the settings to lessSecureApp. Once this is done and smtp SendMail is tried again, it works.

You can do a recursive removal in one line using json.stringify's replacer argument

const removeEmptyValues = obj => (
  JSON.parse(JSON.stringify(obj, (k,v) => v ?? undefined))
)

Usage:

removeEmptyValues({a:{x:1,y:null,z:undefined}}) // Returns {a:{x:1}}

As mentioned in Emmanuel's comment, this technique only worked if your data structure contains only data types that can be put into JSON format (strings, numbers, lists, etc).

(This answer has been updated to use the new Nullish Coalescing operator. depending on browser support needs you may want to use this function instead: (k,v) => v!=null ? v : undefined)

I think Glyph means do something like this:

1. Create a directory ~/.local, if it doesn't already exist.
2. In your ~/.bashrc, ensure that ~/.local/bin is on PATH and that ~/.local is on PYTHONPATH.

3. Create a file ~/.pydistutils.cfg which contains

   [install]
   prefix=~/.local
   

   It's a standard ConfigParser-format file.

4. Download distribute_setup.py and run python distribute_setup.py (no sudo). If it complains about a non-existing site-packages directory, create it manually:

   mkdir -p ~/.local/lib/python2.7/site-packages/

5. Run which easy_install to verify that it's coming from ~/.local/bin

6. Run pip install virtualenv
7. Run pip install virtualenvwrapper
8. Create a virtual env containing folder, say ~/.virtualenvs

9. In ~/.bashrc add

   export WORKON_HOME
   source ~/.local/bin/virtualenvwrapper.sh
   

That's it, no use of sudo at all and your Python environment is in ~/.local, completely separate from the OS's Python. Disclaimer: Not sure how compatible virtualenvwrapper is in this scenario - I couldn't test it on my system :-)

Your results will not be helpful unless the arrays are first sorted. To sort an array, run it through Sort-Object.

$x = @(5,1,4,2,3)
$y = @(2,4,6,1,3,5)

Compare-Object -ReferenceObject ($x | Sort-Object) -DifferenceObject ($y | Sort-Object)

window.location.href = window.location.href

convert a 1-dimensional array into a 2-dimensional array by adding new axis.

a=np.array([10,20,30,40,50,60])

b=a[:,np.newaxis]--it will convert it to two dimension.

If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what's visible at a certain time.

Here's a simple pagination example: http://jsfiddle.net/2ZzZB/56/

That example was on the list of fiddles on the angular.js github wiki, which should be helpful: https://github.com/angular/angular.js/wiki/JsFiddle-Examples

EDIT: http://jsfiddle.net/2ZzZB/16/ to http://jsfiddle.net/2ZzZB/56/ (won't show "1/4.5" if there is 45 results)

Maybe you can use arrow function (ES6+) or the simple old function declaration.

Normal function declaration type (Not ES6+):

<link href="#" onClick={function(event){ func1(event); func2();}}>Trigger here</link>

Anonymous function or arrow function type (ES6+)

<link href="#" onClick={(event) => { func1(event); func2();}}>Trigger here</link>

The second one is the shortest road that I know. Hope it helps you!

As far as I can tell, there are three main contenders: Table-Valued Parameters, delimited list string, and JSON string.

Since 2016, you can use the built-in STRING_SPLIT if you want the delimited route: https://docs.microsoft.com/en-us/sql/t-sql/functions/string-split-transact-sql

That would probably be the easiest/most straightforward/simple approach.

Also since 2016, JSON can be passed as a nvarchar and used with OPENJSON: https://docs.microsoft.com/en-us/sql/t-sql/functions/openjson-transact-sql

That's probably best if you have a more structured data set to pass that may be significantly variable in its schema.

TVPs, it seems, used to be the canonical way to pass more structured parameters, and they are still good if you need that structure, explicitness, and basic value/type checking. They can be a little more cumbersome on the consumer side, though. If you don't have 2016+, this is probably the default/best option.

I think it's a trade off between any of these concrete considerations as well as your preference for being explicit about the structure of your params, meaning even if you have 2016+, you may prefer to explicitly state the type/schema of the parameter rather than pass a string and parse it somehow.

I think this is the easiest way

<!-- Submit Button-->
<button 
  mat-raised-button       
  color="primary"
  [disabled]="!f.valid"
>
  Submit
</button>

While I do like regular expressions in general, for this kind of state-dependent tokenization I believe a simple parser (which in this case is much simpler than that word might make it sound) is probably a cleaner solution, in particular with regards to maintainability, e.g.:

String input = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
List<String> result = new ArrayList<String>();
int start = 0;
boolean inQuotes = false;
for (int current = 0; current < input.length(); current++) {
    if (input.charAt(current) == '\"') inQuotes = !inQuotes; // toggle state
    else if (input.charAt(current) == ',' && !inQuotes) {
        result.add(input.substring(start, current));
        start = current + 1;
    }
}
result.add(input.substring(start));

If you don't care about preserving the commas inside the quotes you could simplify this approach (no handling of start index, no last character special case) by replacing your commas in quotes by something else and then split at commas:

String input = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
StringBuilder builder = new StringBuilder(input);
boolean inQuotes = false;
for (int currentIndex = 0; currentIndex < builder.length(); currentIndex++) {
    char currentChar = builder.charAt(currentIndex);
    if (currentChar == '\"') inQuotes = !inQuotes; // toggle state
    if (currentChar == ',' && inQuotes) {
        builder.setCharAt(currentIndex, ';'); // or '?', and replace later
    }
}
List<String> result = Arrays.asList(builder.toString().split(","));

Windows 10 Users:

I had this issue too. A little bit of investigating helped out though. I had a problem before this one, that 3306 was being used. So what I found out was that port 3306 was being used by another program. Specifically a JDBC program I was trying to learn and I had xammp installed before I tried this JDBC out. So I deleted the whole file and then here I am, where you're at. The issue was that my 'ImagePath'(registry variable) was changed upon installing mySql again. To put it simply, xammp doesn't know where your mysqld.exe is at anymore, or the file is not in the location that you told it to be. Here's how to fix it:

1. Open run (Win + r) and type 'regedit'. This is where you edit your registry.
2. Navigate to: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > MySql

3. Click on mySql and notice the ImagePath variable. Right click 'ImagePath' and click modify.
4. Enter the location of your xammp mySqld file (navigate through xammp to find it) Although it is likely the same as mine.

I got same error because I was trying to run on

To solve this, type command python and when you get these >>> then run any python commands

>>>from classDemo import MyClass
>>>f = MyClass()

That's another solution (Spring Security 3):

    return (!name.equals("anonymousUser")) ? name : null;
}

My answer on how Singletons are bad is always, "they are hard to do right". Many of the foundational components of languages are singletons (classes, functions, namespaces and even operators), as are components in other aspects of computing (localhost, default route, virtual filesystem, etc.), and it is not by accident. While they cause trouble and frustration from time to time, they also can make a lot of things work a LOT better.

The two biggest screw ups I see are: treating it like a global & failing to define the Singleton closure.

Everyone talks about Singleton's as globals, because they basically are. However, much (sadly, not all) of the badness in a global comes not intrinsically from being global, but how you use it. Same goes for Singletons. Actually more so as "single instance" really doesn't need to mean "globally accessible". It is more a natural byproduct, and given all the bad that we know comes from it, we shouldn't be in such a hurry to exploit global accessibility. Once programmers see a Singleton they seem to always access it directly through its instance method. Instead, you should navigate to it just like you would any other object. Most code shouldn't even be aware it is dealing with a Singleton (loose coupling, right?). If only a small bit of code accesses the object like it is a global, a lot of harm is undone. I recommend enforcing it by restricting access to the instance function.

The Singleton context is also really important. The defining characteristic of a Singleton is that there is "only one", but the truth is it is "only one" within some kind of context/namespace. They are usually one of: one per thread, process, IP address or cluster, but can also be one per processor, machine, language namespace/class loader/whatever, subnet, Internet, etc.

The other, less common, mistake is to ignore the Singleton lifestyle. Just because there is only one doesn't mean a Singleton is some omnipotent "always was and always will be", nor is it generally desirable (objects without a begin and end violate all kinds of useful assumptions in code, and should be employed only in the most desperate of circumstances.

If you avoid those mistakes, Singletons can still be a PITA, bit it is ready to see a lot of the worst problems are significantly mitigated. Imagine a Java Singleton, that is explicitly defined as once per classloader (which means it needs a thread safety policy), with defined creation and destruction methods and a life cycle that dictates when and how they get invoked, and whose "instance" method has package protection so it is generally accessed through other, non-global objects. Still a potential source of trouble, but certainly much less trouble.

Sadly, rather than teaching good examples of how to do Singletons. We teach bad examples, let programmers run off using them for a while, and then tell them they are a bad design pattern.

Step 1

• Search → Find → (goto Tab) Mark
• Find what: ^Session.*$
• Enable the checkbox Bookmark line
• Enable the checkbox Regular expression (under Search Mode)
• Click Mark All (this will find the regex and highlights all the lines and bookmark them)

Step 2

• Search → Bookmark → Remove Bookmarked Lines

a=[100,200,300,400,500]
def search(b):
 try:
  k=a.index(b)
  return a[k] 
 except ValueError:
    return 'not found'
print(search(500))

it'll return the object if found else it'll return "not found"

You have to enable auto return in your PayPal account, otherwise it will ignore the return field.

From the documentation (updated to reflect new layout Jan 2019):

Auto Return is turned off by default. To turn on Auto Return:

1. Log in to your PayPal account at https://www.paypal.com or https://www.sandbox.paypal.com The My Account Overview page appears.
2. Click the gear icon top right. The Profile Summary page appears.
3. Click the My Selling Preferences link in the left column.
4. Under the Selling Online section, click the Update link in the row for Website Preferences. The Website Payment Preferences page appears
5. Under Auto Return for Website Payments, click the On radio button to enable Auto Return.
6. In the Return URL field, enter the URL to which you want your payers redirected after they complete their payments. NOTE: PayPal checks the Return URL that you enter. If the URL is not properly formatted or cannot be validated, PayPal will not activate Auto Return.
7. Scroll to the bottom of the page, and click the Save button.

IPN is for instant payment notification. It will give you more reliable/useful information than what you'll get from auto-return.

Documentation for IPN is here: https://www.x.com/sites/default/files/ipnguide.pdf

Online Documentation for IPN: https://developer.paypal.com/docs/classic/ipn/gs_IPN/

The general procedure is that you pass a notify_url parameter with the request, and set up a page which handles and validates IPN notifications, and PayPal will send requests to that page to notify you when payments/refunds/etc. go through. That IPN handler page would then be the correct place to update the database to mark orders as having been paid.

Here is a sample code showing how to align text using UILabel:

label = [[UILabel alloc] initWithFrame:CGRectMake(60, 30, 200, 12)];
label.textAlignment = NSTextAlignmentCenter;

The zoom property sounds as though it's perfect for Adam Ernst as it suits his target device. However, for those who need a solution to this and have to support as many devices as possible you can do the following:

<img src="..." onload="this.width/=2;this.onload=null;" />

The reason for the this.onload=null addition is to avoid older browsers that sometimes trigger the load event twice (which means you can end up with quater-sized images). If you aren't worried about that though you could write:

<img src="..." onload="this.width/=2;" />

Which is quite succinct.

In order to get the desired result, you must set "box-sizing: border-box" vs. the default which is "box-sizing: content-box". This is precisely the issue you are referring to (From MDN):

content-box

This is the initial and default value as specified by the CSS standard. The width and height properties are measured including only the content, but not the padding, border or margin.

border-box

The width and height properties include the content, the padding and border, but not the margin."

Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing

Compatibility for this CSS is good.

Unit Test:- Unit testing is particularly used to test the product component by component specially while the product is under development. Junit and Nunit type of tools will also help you to test the product as per the Unit. **Rather than solving the issues after the Integration it is always comfortable to get it resolved early in the development.

Functional Testing:- As for as the Testing is concerned there are two main types of Testing as 1.Functional Test 2.Non-Functional Test.

Non-Functional Test is a test where a Tester will test that The product will perform all those quality attributes that customer doesn't mention but those quality attributes should be there. Like:-Performance,Usability,Security,Load,Stress etc. but in the Functional Test:- The customer is already present with his requirements and those are properly documented,The testers task is to Cross check that whether the Application Functionality is performing according to the Proposed System or not. For that purpose Tester should test for the Implemented functionality with the proposed System.

When dealing with Uniform Resource Locator(URL) s there are certain syntax standards, in this particular situation we are dealing with Reserved Characters.

As up to RFC 3986, Reserved Characters may (or may not) be defined as delimiters by the generic syntax, by each scheme-specific syntax, or by the implementation-specific syntax of a URI's dereferencing algorithm; And asterisk(*) is a Reserved Character.

The best practice is to use Unreserved Characters in URLs or you can try encoding it.

Keep digging :

• When to Encode or Decode (RFC 3986)

This is how you use the TensorBoard callback:

from keras.callbacks import TensorBoard

tensorboard = TensorBoard(log_dir='./logs', histogram_freq=0,
                          write_graph=True, write_images=False)
# define model
model.fit(X_train, Y_train,
          batch_size=batch_size,
          epochs=nb_epoch,
          validation_data=(X_test, Y_test),
          shuffle=True,
          callbacks=[tensorboard])

For those who want to use Lodash can use the _.words function:

var str = "Random String";_x000D_
var wordCount = _.size(_.words(str));_x000D_
console.log(wordCount);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

Given that you're only converting to ints to then perform a comparison, I'd just switch the table definition around to using varchar also:

Create table #myTempTable
(
num varchar(12)
)
insert into #myTempTable (num) values (1),(2),(3),(4),(5)

and remove all of the attempted CONVERTs from the rest of the query.

 SELECT a.name, a.value AS value, COUNT(*) AS pocet   
 FROM 
 (SELECT item.name, value.value 
  FROM mdl_feedback AS feedback 
  INNER JOIN mdl_feedback_item AS item 
       ON feedback.id = item.feedback
  INNER JOIN mdl_feedback_value AS value 
       ON item.id = value.item 
   WHERE item.typ = 'multichoicerated' AND item.feedback IN (43)
 ) AS a 
 INNER JOIN #myTempTable 
     on a.value = #myTempTable.num
 GROUP BY a.name, a.value ORDER BY a.name

The easiest way to achieve this, without changing the HTML table-based structure, is to use a class-name on the tr elements containing a header, such as .header, to give:

<table border="0">
  <tr class="header">
    <td colspan="2">Header</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>
  <tr class="header">
    <td colspan="2">Header</td>
  </tr>
  <tr>
    <td>date</td>
    <td>data</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>
  <tr>
    <td>data</td>
    <td>data</td>
  </tr>
</table>

And the jQuery:

// bind a click-handler to the 'tr' elements with the 'header' class-name:
$('tr.header').click(function(){
    /* get all the subsequent 'tr' elements until the next 'tr.header',
       set the 'display' property to 'none' (if they're visible), to 'table-row'
       if they're not: */
    $(this).nextUntil('tr.header').css('display', function(i,v){
        return this.style.display === 'table-row' ? 'none' : 'table-row';
    });
});

JS Fiddle demo.

In the linked demo I've used CSS to hide the tr elements that don't have the header class-name; in practice though (despite the relative rarity of users with JavaScript disabled) I'd suggest using JavaScript to add the relevant class-names, hiding and showing as appropriate:

// hide all 'tr' elements, then filter them to find...
$('tr').hide().filter(function () {
    // only those 'tr' elements that have 'td' elements with a 'colspan' attribute:
    return $(this).find('td[colspan]').length;
    // add the 'header' class to those found 'tr' elements
}).addClass('header')
    // set the display of those elements to 'table-row':
  .css('display', 'table-row')
    // bind the click-handler (as above)
  .click(function () {
    $(this).nextUntil('tr.header').css('display', function (i, v) {
        return this.style.display === 'table-row' ? 'none' : 'table-row';
    });
});

I don't know if the location is the same for other versions.

Do you mean design as in 'graphic representation of tables' or just plain old 'engineering kind of design'. If it's the latter, use FlameRobin, version 0.9.0 has just been released.

If it's the former, then use DBDesigner. Yup, that uses Java.

Or maybe you meant something more like MS Access. Then Kexi should be right for you.

There are three possible ways to do that.

1. Option

   SELECT  lt.* FROM    table_left lt
   LEFT JOIN
       table_right rt
   ON      rt.value = lt.value
   WHERE   rt.value IS NULL
   

2. Option

   SELECT  lt.* FROM    table_left lt
   WHERE   lt.value NOT IN
   (
   SELECT  value
   FROM    table_right rt
   )
   

3. Option

   SELECT  lt.* FROM    table_left lt
   WHERE   NOT EXISTS
   (
   SELECT  NULL
   FROM    table_right rt
   WHERE   rt.value = lt.value
   )
   

I could have commented but I have less rep for that. Samrat's answer did the job for me. It's better to see the current directory path through the following code.

    File directory = new File("./");
    System.out.println(directory.getAbsolutePath());

I simply used it to rectify an issue I was facing in my project. Be sure to use ./ to back to the parent directory of the current directory.

    ./test/conf/appProperties/keystore 

The approved solution doesn't work in my case, so my solution is the following one:

    ''' The column name in the example case is "Unnamed: 7"
 but it works with any other name ("Unnamed: 0" for example). '''

        df.rename({"Unnamed: 7":"a"}, axis="columns", inplace=True)

        # Then, drop the column as usual.

        df.drop(["a"], axis=1, inplace=True)

Hope it helps others.

EDIT : this answer is old. Usage of MD5 is now discouraged as it can easily be broken.

MD5 must be good enough for you I imagine? You can achieve it with MessageDigest.

MessageDigest.getInstance("MD5");

There are also other algorithms listed here.

And here's an third party version of it, if you really want: Fast MD5

As ROM size does not count one does not need any additional RAM besides the TCP buffers. Just implement a big finite-state machine. Each state represents a multi-set of numbers read in. After reading a million numbers one has just to print the numbers corresponding to the reached state.

a vue3 replacement of this answer:

// Vue3

const app = Vue.createApp({})
app.config.globalProperties.$hostname = 'http://localhost:3000'


app.component('a-child-component', {
  mounted() {
    console.log(this.$hostname) // 'http://localhost:3000'
  }
})

I avoid RegExp at all costs. Here is another thing you can do:

"good_luck_buddy".split('_').slice(1).join('_')

Sadly @Andrés Montoya answer has a flaw which is related to how he compares the obj. I found a solution here which should solve this:

const now = Date.now().valueOf() / 1000

if (typeof decoded.exp !== 'undefined' && decoded.exp < now) {
    throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}
if (typeof decoded.nbf !== 'undefined' && decoded.nbf > now) {
    throw new Error(`token expired: ${JSON.stringify(decoded)}`)
}

Can't stand aside,

So we have linear system:

A₁ * x + B₁ * y = C₁
A₂ * x + B₂ * y = C₂

let's do it with Cramer's rule, so solution can be found in determinants:

x = D_x/D
y = D_y/D

where D is main determinant of the system:

A₁ B₁
A₂ B₂

and D_x and D_y can be found from matricies:

C₁ B₁
C₂ B₂

and

A₁ C₁
A₂ C₂

(notice, as C column consequently substitues the coef. columns of x and y)

So now the python, for clarity for us, to not mess things up let's do mapping between math and python. We will use array L for storing our coefs A, B, C of the line equations and intestead of pretty x, y we'll have [0], [1], but anyway. Thus, what I wrote above will have the following form further in the code:

for D

L1[0] L1[1]
L2[0] L2[1]

for D_x

L1[2] L1[1]
L2[2] L2[1]

for D_y

L1[0] L1[2]
L2[0] L2[2]

Now go for coding:

line - produces coefs A, B, C of line equation by two points provided,
intersection - finds intersection point (if any) of two lines provided by coefs.

from __future__ import division 

def line(p1, p2):
    A = (p1[1] - p2[1])
    B = (p2[0] - p1[0])
    C = (p1[0]*p2[1] - p2[0]*p1[1])
    return A, B, -C

def intersection(L1, L2):
    D  = L1[0] * L2[1] - L1[1] * L2[0]
    Dx = L1[2] * L2[1] - L1[1] * L2[2]
    Dy = L1[0] * L2[2] - L1[2] * L2[0]
    if D != 0:
        x = Dx / D
        y = Dy / D
        return x,y
    else:
        return False

Usage example:

L1 = line([0,1], [2,3])
L2 = line([2,3], [0,4])

R = intersection(L1, L2)
if R:
    print "Intersection detected:", R
else:
    print "No single intersection point detected"

The code that is written in the question has a bug in it

Your arraylist contains strings of " 1" " 3" " 4" " 9" and " 2" (note the spaces)

So IndexOf(4) will find nothing because 4 is an int, and even "tostring" would convert it to of "4" and not " 4", and nothing will get removed.

An arraylist is the correct way to go to do what you want.

The OP says, for unknown reasons, "I prefer it without an arraylist or list."

If the type you are referring to is a primitive (you mention integers, but you don't say if you mean int or Integer), then you can use one of the NIO Buffer classes like java.nio.IntBuffer. These act a lot like StringBuffer does - they act as buffers for a list of the primitive type (buffers exist for all the primitives but not for Objects), and you can wrap a buffer around an array and/or extract an array from a buffer.

Note that the javadocs say, "The capacity of a buffer is never negative and never changes." It's still just a wrapper around an array, but one that's nicer to work with. The only way to effectively expand a buffer is to allocate() a larger one and use put() to dump the old buffer into the new one.

If it's not a primitive, you should probably just use List, or come up with a compelling reason why you can't or won't, and maybe somebody will help you work around it.

You can find a short collection of useful list functions here.

list.pop(index)

>>> l = ['a', 'b', 'c', 'd']
>>> l.pop(0)
'a'
>>> l
['b', 'c', 'd']
>>> 

del list[index]

>>> l = ['a', 'b', 'c', 'd']
>>> del l[0]
>>> l
['b', 'c', 'd']
>>> 

These both modify your original list.

Others have suggested using slicing:

• Copies the list
• Can return a subset

Also, if you are performing many pop(0), you should look at collections.deque

from collections import deque
>>> l = deque(['a', 'b', 'c', 'd'])
>>> l.popleft()
'a'
>>> l
deque(['b', 'c', 'd'])

• Provides higher performance popping from left end of the list

Based off Simon McKenzie's answer to this question, I'd suggest using a pair of methods like this:

    public static void ZipFolder(string sourceFolder, string zipFile)
    {
        if (!System.IO.Directory.Exists(sourceFolder))
            throw new ArgumentException("sourceDirectory");

        byte[] zipHeader = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

        using (System.IO.FileStream fs = System.IO.File.Create(zipFile))
        {
            fs.Write(zipHeader, 0, zipHeader.Length);
        }

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic source = shellApplication.NameSpace(sourceFolder);
        dynamic destination = shellApplication.NameSpace(zipFile);

        destination.CopyHere(source.Items(), 20);
    }

    public static void UnzipFile(string zipFile, string targetFolder)
    {
        if (!System.IO.Directory.Exists(targetFolder))
            System.IO.Directory.CreateDirectory(targetFolder);

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic compressedFolderContents = shellApplication.NameSpace(zipFile).Items;
        dynamic destinationFolder = shellApplication.NameSpace(targetFolder);

        destinationFolder.CopyHere(compressedFolderContents);
    }
}

Simple :

    <div style='overflow-x:scroll;overflow-y:scroll;width:100%;height:100%'>

Refer this link Get Keycode from key press and char value for any key code

$('input#inp').keyup(function(e){
   $(this).val(String.fromCharCode(e.keyCode)); 
   $('div#output').html('Keycode : ' + e.keyCode);  
});

You could also wrap the transaction up into it's own stored procedure and handle it that way instead of doing transactions in C# itself.

If your goal is to keep a local copy of the repository for easy backup or for sticking onto an external drive or sharing via cloud storage (Dropbox, etc) you may want to use a bare repository. This allows you to create a copy of the repository without a working directory, optimized for sharing.

For example:

$ git init --bare ~/repos/myproject.git
$ cd /path/to/existing/repo
$ git remote add origin ~/repos/myproject.git
$ git push origin master

Similarly you can clone as if this were a remote repo:

$ git clone ~/repos/myproject.git

You can import them like this:

In [7]: import scipy, numpy, math                                                          

In [8]: scipy.math.factorial, numpy.math.factorial, math.factorial
Out[8]: 
(<function math.factorial>,                                                                
 <function math.factorial>,                                                                
 <function math.factorial>)

scipy.math.factorial and numpy.math.factorial seem to simply be aliases/references for/to math.factorial, that is scipy.math.factorial is math.factorial and numpy.math.factorial is math.factorial should both give True.

I know this basic method:

1)

<input type=”image” src=”submit.png”> (in any place)

2)

<form name=”print”>
<input type=”hidden” name=”a” value=”<?= $a ?>”>
<input type=”hidden” name=”b” value=”<?= $b ?>”>
<input type=”hidden” name=”c” value=”<?= $c ?>”>
</form>

3)

<script>
$(‘#submit’).click(function(){
    open(”,”results”);
    with(document.print)
    {
        method = “POST”;
        action = “results.php”;
        target = “results”;
        submit();
    }
});
</script>

Works!

I also have a site that has numerous urls with urlencoded characters. I am finding that many web APIs (including Google webmaster tools and several Drupal modules) trip over urlencoded characters. Many APIs automatically decode urls at some point in their process and then use the result as a URL or HTML. When I find one of these problems, I usually double encode the results (which turns %2f into %252f) for that API. However, this will break other APIs which are not expecting double encoding, so this is not a universal solution.

Personally I am getting rid of as many special characters in my URLs as possible.

Also, I am using id numbers in my URLs which do not depend on urldecoding:

example.com/blog/my-amazing-blog%2fstory/yesterday

becomes:

example.com/blog/12354/my-amazing-blog%2fstory/yesterday

in this case, my code only uses 12354 to look for the article, and the rest of the URL gets ignored by my system (but is still used for SEO.) Also, this number should appear BEFORE the unused URL components. that way, the url will still work, even if the %2f gets decoded incorrectly.

Also, be sure to use canonical tags to ensure that url mistakes don't translate into duplicate content.

It should also be noted that it might also be important to analyze the results of the micro benchmark when comparing different implementations. Therefore a significance test should be made.

This is because implementation A might be faster during most of the runs of the benchmark than implementation B. But A might also have a higher spread, so the measured performance benefit of A won't be of any significance when compared with B.

So it is also important to write and run a micro benchmark correctly, but also to analyze it correctly.

In your Installer class, add a handler for the AfterInstall event. You can then call the ServiceController in the event handler to start the service.

using System.ServiceProcess;
public ServiceInstaller()
{
    //... Installer code here
    this.AfterInstall += new InstallEventHandler(ServiceInstaller_AfterInstall);
}

void ServiceInstaller_AfterInstall(object sender, InstallEventArgs e)
{
    ServiceInstaller serviceInstaller = (ServiceInstaller)sender;

    using (ServiceController sc = new ServiceController(serviceInstaller.ServiceName))
    {
             sc.Start();
    }
}

Now when you run InstallUtil on your installer, it will install and then start up the service automatically.

If you are using OpenLDAP (i.e. slapd) which is common on Linux servers, then you must enable the memberof overlay to be able to match against a filter using the (memberOf=XXX) attribute.

Also, once you enable the overlay, it does not update the memberOf attributes for existing groups (you will need to delete out the existing groups and add them back in again). If you enabled the overlay to start with, when the database was empty then you should be OK.

According to Yashu's instructions, I wrote the following function (it's PL/SQL code, but it should be easily adaptable to any other language).

FUNCTION field(str IN VARCHAR2) RETURN VARCHAR2 IS
    C_NEWLINE CONSTANT CHAR(1) := '
'; -- newline is intentional

    v_aux VARCHAR2(32000);
    v_has_double_quotes BOOLEAN;
    v_has_comma BOOLEAN;
    v_has_newline BOOLEAN;
BEGIN
    v_has_double_quotes := instr(str, '"') > 0;
    v_has_comma := instr(str,',') > 0;
    v_has_newline := instr(str, C_NEWLINE) > 0;

    IF v_has_double_quotes OR v_has_comma OR v_has_newline THEN
        IF v_has_double_quotes THEN
            v_aux := replace(str,'"','""');
        ELSE
            v_aux := str;
        END IF;
        return '"'||v_aux||'"';
    ELSE
        return str;
    END IF;
END;

You can not give order by because order by does a "full scan" on a table.

The following query is better:

SELECT * FROM table WHERE id = (SELECT MAX(id) FROM table);

write return(secondmethod) inside of the first method

I had same issue before: the server name was not appearing in server while configuring with eclipse

I tried all the solutions which are provided over here, but they didn't work for me.

I resolved it, by simply following these simple tips

Step1: Windows --> Preferences --> Server --> Run time Environments --> Add --> select the tomcat version which was unavailable before --> next --> browse the location of your server with same version

Step2: go to servers and select your server version --> next --> Finish

Issue resolved!!! :)

var input = "12342";
var output = input.Substring(0, input.Length - 1); 

or

var output = input.Remove(input.Length - 1);

createOrReplaceTempView creates (or replaces if that view name already exists) a lazily evaluated "view" that you can then use like a hive table in Spark SQL. It does not persist to memory unless you cache the dataset that underpins the view.

scala> val s = Seq(1,2,3).toDF("num")
s: org.apache.spark.sql.DataFrame = [num: int]

scala> s.createOrReplaceTempView("nums")

scala> spark.table("nums")
res22: org.apache.spark.sql.DataFrame = [num: int]

scala> spark.table("nums").cache
res23: org.apache.spark.sql.Dataset[org.apache.spark.sql.Row] = [num: int]

scala> spark.table("nums").count
res24: Long = 3

The data is cached fully only after the .count call. Here's proof it's been cached:

Related SO: spark createOrReplaceTempView vs createGlobalTempView

Relevant quote (comparing to persistent table): "Unlike the createOrReplaceTempView command, saveAsTable will materialize the contents of the DataFrame and create a pointer to the data in the Hive metastore." from https://spark.apache.org/docs/latest/sql-programming-guide.html#saving-to-persistent-tables

Note : createOrReplaceTempView was formerly registerTempTable

Add a <version> element after the <plugin> <artifactId> in your pom.xml file. Find the following text:

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>

Add the version tag to it:

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>2.3.2</version>

The warning should be resolved.

Regarding this:

'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing

Many people have mentioned why the issue is happening, but fail to suggest a fix. All I needed to do was to go into my POM file for my project, and add the <version> tag as shown above.

To discover the version number, one way is to look in Maven's output after it finishes running. Where you are missing version numbers, Maven will display its default version:

[INFO] --- maven-compiler-plugin:2.3.2:compile (default-compile) @ entities ---

Take that version number (as in the 2.3.2 above) and add it to your POM, as shown.

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

How can I roll back my previous 4 commits locally in a branch?

Which means, you are not creating new branch and going into detached state. New way of doing that is:

git switch --detach revison

The modulo operator % in C and C++ is defined for two integers, however, there is an fmod() function available for usage with doubles.

os.path.splitext() won't work if there are multiple dots in the extension.

For example, images.tar.gz

>>> import os
>>> file_path = '/home/dc/images.tar.gz'
>>> file_name = os.path.basename(file_path)
>>> print os.path.splitext(file_name)[0]
images.tar

You can just find the index of the first dot in the basename and then slice the basename to get just the filename without extension.

>>> import os
>>> file_path = '/home/dc/images.tar.gz'
>>> file_name = os.path.basename(file_path)
>>> index_of_dot = file_name.index('.')
>>> file_name_without_extension = file_name[:index_of_dot]
>>> print file_name_without_extension
images

You need to do:

import sqlitedbx

def main():
    db = sqlitedbx.SqliteDBzz()
    db.connect()

if __name__ == "__main__":
    main()

Example:

$number = 4;
print "You have the {$number}th edition book";
//output: "You have the 4th edition book";

Without curly braces PHP would try to find a variable named $numberth, that doesn't exist!

I wanted to post a quick answer that while using source ~/.bash_profile or the answers mentioned above works, one thing to mention is that this only reloads your bash profile in the current tab or session you are viewing. If you wish to reload your bash profile on every tab/shell, you need to enter this command manually in each of them.

If you use iTerm, you can use CMD?+Shift+I to enter a command into all current tabs. For terminal it may be useful to reference this issue;

The ToString function has many overloads - the method group would be the group consisting of all the different overloads for that function.

await setTimeout(()=>{}, 200);

Will work if your Node version is 15 and above.

Use docker inspect.

$ docker ps # get conteiner id
$ docker inspect 4abbef615af7
[{
    "ID": "4abbef615af780f24991ccdca946cd50d2422e75f53fb15f578e14167c365989",
    "Created": "2014-01-08T07:13:32.765612597Z",
    "Path": "/bin/bash",
    "Args": [
        "-c",
        "/start web"
    ],
    "Config": {
        "Hostname": "4abbef615af7",
...

Can get ip as follows.

$ docker inspect -format="{{ .NetworkSettings.IPAddress }}" 2a5624c52119
172.17.0.24

I know this is an old question but according what @mikejones1477 said, modern front end libraries and frameworks escape the text giving you protection against XSS. The reason why cookies are not a secure method using credentials is that cookies doesn't prevent CSRF when localStorage does (also remember that cookies are accessible by javascript too, so XSS isn't the big problem here), this answer resume why.

The reason storing an authentication token in local storage and manually adding it to each request protects against CSRF is that key word: manual. Since the browser is not automatically sending that auth token, if I visit evil.com and it manages to send a POST http://example.com/delete-my-account, it will not be able to send my authn token, so the request is ignored.

Of course httpOnly is the holy grail but you can't access from reactjs or any js framework beside you still have CSRF vulnerability. My recommendation would be localstorage or if you want to use cookies make sure implemeting some solution to your CSRF problem like django does.

Regarding with the CDN's make sure you're not using some weird CDN, for example CDN like google or bootstrap provide, are maintained by the community and doesn't contain malicious code, if you are not sure, you're free to review.

I had the same problem. Open the cmd and type:

python -m pip install pylint

XSD is to validate the document, and contains metadata about the XML whereas WSDL is to describe the webservice location and operations.

When I used the code mysqld_safe --skip-grant-tables & but I get the error:

mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.

$ systemctl stop  mysql.service
$ ps -eaf|grep mysql
$ mysqld_safe --skip-grant-tables &

I solved:

$ mkdir -p /var/run/mysqld
$ chown mysql:mysql /var/run/mysqld

Now I use the same code mysqld_safe --skip-grant-tables & and get

mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

If I use $ mysql -u root I'll get :

mysql>

Now time to change password:

mysql> use mysql
mysql> describe user;

Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A

Database changed

mysql> FLUSH PRIVILEGES;
mysql> SET PASSWORD FOR root@'localhost' = PASSWORD('newpwd');

or If you have a mysql root account that can connect from everywhere, you should also do:

UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';

Alternate Method:

   USE mysql
   UPDATE user SET Password = PASSWORD('newpwd')
   WHERE Host = 'localhost' AND User = 'root';

And if you have a root account that can access from everywhere:

 USE mysql
 UPDATE user SET Password = PASSWORD('newpwd')
 WHERE Host = '%' AND User = 'root';`enter code here

now need to quit from mysql and stop/start

FLUSH PRIVILEGES;
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

now again ` mysql -u root -p' and use the new password to get

mysql>

Try this one :

var time = new Date().toJSON();

Any Class that implements System.Web.IHttpHandler Interface becomes HttpHandler. And this class run as processes in response to a request made to the ASP.NET Site.

The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler(The Class that implements System.Web.IHttpHandler Interface).

You can create your own custom HTTP handlers that render custom output to the browser.

Some ASP.NET default handlers are:

1. Page Handler (.aspx) – Handles Web pages
2. User Control Handler (.ascx) – Handles Web user control pages
3. Web Service Handler (.asmx) – Handles Web service pages
4. Trace Handler (trace.axd) – Handles trace functionality

If you search the first char of string in Sql string

SELECT CHARINDEX('char', 'my char')

=> return 4

Assuming the type in your example, definitely prefer to initialize fields in the constructor. The exceptional cases are:

• Fields in static classes/methods
• Fields typed as static/final/et al

I always think of the field listing at the top of a class as the table of contents (what is contained herein, not how it is used), and the constructor as the introduction. Methods of course are chapters.

Something none of the other answers touch on is that your first loop is indexing though the list. Whereas the for-each loop is using an Iterator. Some lists like LinkedList will iterate faster with an Iterator versus get(i). This is because because link list's iterator keeps track of the current pointer. Whereas each get in your for i=0 to 9 has to recompute the offset into the linked list. In general, its better to use for-each or an Iterator because it will be using Collections iterator, which in theory is optimized for the collection type.

Pass by value for small types.

Pass by const references for big types (the definition of big can vary between machines) BUT, in C++11, pass by value if you are going to consume the data, since you can exploit move semantics. For example:

class Person {
 public:
  Person(std::string name) : name_(std::move(name)) {}
 private:
  std::string name_;
};

Now the calling code would do:

Person p(std::string("Albert"));

And only one object would be created and moved directly into member name_ in class Person. If you pass by const reference, a copy will have to be made for putting it into name_.

It's compiled to bytecode which can be used much, much, much faster.

The reason some files aren't compiled is that the main script, which you invoke with python main.py is recompiled every time you run the script. All imported scripts will be compiled and stored on the disk.

Important addition by Ben Blank:

It's worth noting that while running a compiled script has a faster startup time (as it doesn't need to be compiled), it doesn't run any faster.

If you want to work with python 3, it's very simple:

print("If there was a birth every 7 second, there would be %d births." % (births))

From the Google Font Directory examples:

@font-face {
  font-family: 'Tangerine';
  font-style: normal;
  font-weight: normal;
  src: local('Tangerine'), url('http://example.com/tangerine.ttf') format('truetype');
}
body {
  font-family: 'Tangerine', serif;
  font-size: 48px;
}

This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf

Here are some good sites:

• Good primer:

I have a simpler and elegant solution that doesn't mess up with classes, styles, opacities and stuff.

For the draggable element - you add 'start' event which will execute every time you try to move the element somewhere. You will have a condition which move is not legal. For the moves that are illegal - prevent them with 'e.preventDefault();' like in the code below.

    $(".disc").draggable({
        revert: "invalid", 
        cursor: "move",
        start: function(e, ui){                
            console.log("element is moving");

            if(SOME_CONDITION_FOR_ILLEGAL_MOVE){
                console.log("illegal move");
                //This will prevent moving the element from it's position
                e.preventDefault();
            }    

        }
    });

You are welcome :)

first, you need to find the toolbox that you need. There are many people developing 3rd party toolboxes for Matlab, so there isn't just one single place where you can find "the image processing toolbox". That said, a good place to start looking is the Matlab Central which is a Mathworks-run site for exchanging all kinds of Matlab-related material.

Once you find a toolbox you want, it will be in some compressed format, and its developers might have a "readme" file that details on how to install it. If it isn't the case, a generic way to attempt installation is to place the toolbox in any directory on your drive, and then add it to Matlab path, e.g., going to File -> Set Path... -> Add Folder or Add with Subfolders (I'm writing for memory but this is definitely close).

Otherwise, you can extract all .m files in your working directory, if you don't want to use downloaded toolbox in more than one project.

For those who still have problems (Cannot pass parameter 2 by reference), define a variable with null value, not just pass null to PDO:

bindValue(':param', $n = null, PDO::PARAM_INT);

Hope this helps.

It can be because you have jpa dependendencies and plugins...

just comment it if not use(build.gradle or pom file)

e. g.

// kotlin("plugin.jpa") version "1.3.61"

// implementation("org.springframework.boot:spring-boot-starter-data-jpa")

Shefali's solution for UIImageView works great, but it needs a little modification:

- (void)pinch:(UIPinchGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateEnded
        || gesture.state == UIGestureRecognizerStateChanged) {
        NSLog(@"gesture.scale = %f", gesture.scale);

        CGFloat currentScale = self.frame.size.width / self.bounds.size.width;
        CGFloat newScale = currentScale * gesture.scale;

        if (newScale < MINIMUM_SCALE) {
            newScale = MINIMUM_SCALE;
        }
        if (newScale > MAXIMUM_SCALE) {
            newScale = MAXIMUM_SCALE;
        }

        CGAffineTransform transform = CGAffineTransformMakeScale(newScale, newScale);
        self.transform = transform;
        gesture.scale = 1;
    }
}

(Shefali's solution had the downside that it did not scale continuously while pinching. Furthermore, when starting a new pinch, the current image scale was reset.)

Here is the Swift 4 version

extension NSDictionary{

func toString() throws -> String? {
    do {
        let data = try JSONSerialization.data(withJSONObject: self, options: .prettyPrinted)
        return String(data: data, encoding: .utf8)
    }
    catch (let error){
        throw error
    }
}

}

Usage Example

do{
    let jsonString = try dic.toString()
    }
    catch( let error){
        print(error.localizedDescription)
    }

Or if you are sure it is valid dictionary then you can use

let jsonString = try? dic.toString()

You can do like this, to get the currently selected value:

$('#myDropdownID').val();

& to get the currently selected text:

$('#myDropdownID:selected').text();

View this web: http://www.w3resource.com/sql/subqueries/multiplee-row-column-subqueries.php

Use example

select ord_num, agent_code, ord_date, ord_amount  
from orders  
where(agent_code, ord_amount) IN  
(SELECT agent_code, MIN(ord_amount)  
FROM orders   
GROUP BY agent_code);    

For components inside *ngIf, another approach:

The component I wanted to select was inside a div's *ngIf statement, and @jsgoupil's answer above probably works (Thanks @jsgoupil!), but I ended up finding a way to avoid using *ngIf, by using CSS to hide the element.

When the condition in the [className] is true, the div gets displayed, and naming the component using # works and it can be selected from within the typescript code. When the condition is false, it's not displayed, and I don't need to select it anyway.

Component:

@Component({
    selector: 'bla',
    templateUrl: 'bla.component.html',
    styleUrls: ['bla.component.scss']
})
export class BlaComponent implements OnInit, OnDestroy {
    @ViewChild('myComponentWidget', {static: true}) public myComponentWidget: any;
    @Input('action') action: ActionType; // an enum defined in our code. (action could also be declared locally)

constructor() {
   etc;
}

// this lets you use an enum in the HMTL (ActionType.SomeType)
public get actionTypeEnum(): typeOf ActionType {
    return ActionType;
}

public someMethodXYZ: void {
    this.myComponentWidget.someMethod(); // use it like that, assuming the method exists
}

and then in the bla.component.html file:

<div [className]="action === actionTypeEnum.SomeType ? 'show-it' : 'do-not-show'">

    <my-component #myComponentWidget etc></my-component>
</div>
<div>
    <button type="reset" class="bunch-of-classes" (click)="someMethodXYZ()">
        <span>XYZ</span>
    </button>
</div>   

and the CSS file:

 ::ng-deep {
    .show-it {
         display: block;   // example, actually a lot more css in our code
    }
    .do-not-show {
        display: none'; 
    }
}

You can use Calendar.

     Calendar rightNow = Calendar.getInstance();

Calendar

Date4j alternative to Date, Calendar, and related Java classes

Also there is mongoexport for that, but I'm not sure since which version it is available.

Example:

mongoexport -d dbname -c collection --jsonArray --pretty --quiet --out output.json

int sign(float n)
{     
  union { float f; std::uint32_t i; } u { n };
  return 1 - ((u.i >> 31) << 1);
}

This function assumes:

• binary32 representation of floating point numbers
• a compiler that make an exception about the strict aliasing rule when using a named union

Here are some Tips:

DELETE

• 200 (if you want send some additional data in the Response) or 204 (recommended).

• 202 Operation deleted has not been committed yet.

• If there's nothing to delete, use 204 or 404 (DELETE operation is idempotent, delete an already deleted item is operation successful, so you can return 204, but it's true that idempotent doesn't necessarily imply the same response)

Other errors:

• 400 Bad Request (Malformed syntax or a bad query is strange but possible).
• 401 Unauthorized Authentication failure
• 403 Forbidden: Authorization failure or invalid Application ID.
• 405 Not Allowed. Sure.
• 409 Resource Conflict can be possible in complex systems.
• And 501, 502 in case of errors.

PUT

If you're updating an element of a collection

• 200/204 with the same reasons as DELETE above.
• 202 if the operation has not been commited yet.

The referenced element doesn't exists:

• PUT can be 201 (if you created the element because that is your behaviour)

• 404 If you don't want to create elements via PUT.

• 400 Bad Request (Malformed syntax or a bad query more common than in case of DELETE).

• 401 Unauthorized

• 403 Forbidden: Authentication failure or invalid Application ID.

• 405 Not Allowed. Sure.

• 409 Resource Conflict can be possible in complex systems, as in DELETE.

• 422 Unprocessable entity It helps to distinguish between a "Bad request" (e.g. malformed XML/JSON) and invalid field values

• And 501, 502 in case of errors.

Just append() the text nodes:

$('#replyBox').append(quote); 

http://jsfiddle.net/nQErc/

As said by others, RowDataBound or RowCreated event should work but if you want to avoid events declaration and put the whole code just below DataBind function call, you can do the following:

GridView1.DataBind()
If GridView1.Rows.Count > 0 Then
    GridView1.HeaderRow.Cells(0).Visible = False
    For i As Integer = 0 To GridView1.Rows.Count - 1
        GridView1.Rows(i).Cells(0).Visible = False
    Next
End If

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>

$q=$_GET["q"];

$con = mysql_connect('localhost', 'peter', 'abc123');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());

mysql_select_db("ajax_demo", $con);

$sql="SELECT * FROM user WHERE id = '".$q."'";

$result = mysql_query($sql);

echo "<table border='1'>

mysql_close($con);

To resolve this issue follow the below given steps-

1). In inteli Go to File> Setting Option and Search for Vm Option In the field of Vm Option for Importer give value -Xmx512m. Intelij Setting Options

2). Go to Control Pannel Select View by :Large icons then Go to Java one promp window will appear with name java control pannel then go to java Java VM Options

select view option. java view options

In Java Run time Environment Setting pass Run time Parameters as -Xmx1024m.

3). If above given options does not work then change the size of pom.xml

As others pointed out, the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install. Another option would be to use the manager application if it is installed (this is not always the case), if it's properly configured (i.e. if you have the credentials of a user assigned to the appropriate group) and if it you can access it over an insecure network like Internet (but this is very unlikely and you didn't mention any VPN access). So this leaves you with the webappdirectory.

Now, if Tomcat is installed and running on bilgin.ath.cx (as this is the machine where you uploaded the files), I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache. In that case, I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files (mod_jk?, mod_proxy?). You should either give us more details or discuss this with your hosting provider.

Update: As expected, the bilgin.ath.cx is using Apache Tomcat + Apache HTTPD + mod_jk. The configuration usually involves two files: the worker.properties file to configure the workers and the httpd.conf for Apache. Now, without seeing the current configuration, it's not easy to give a definitive answer but, basically, you may have to add a JkMount directive in Apache httpd.conf for your new webapp¹. Refer to the mod_jk documentation, it has a simple configuration example. Note that modifying httpd.conf will require access to (obviously) and proper rights and that you'll have to restart Apache after the modifications.

_{¹ I don't think you'll need to define a new worker if you are deploying to an already used Tomcat instance, especially if this sounds like Chinese for you :)}

Antonio's answer

CONCAT(REPLACE(FORMAT(number,0),',','.'),',',SUBSTRING_INDEX(FORMAT(number,2),'.',-1))

is wrong; it may produce incorrect results!

For example, if "number" is 12345.67, the resulting string would be:

'12.346,67'

instead of

'12.345,67'

because FORMAT(number,0) rounds "number" up if fractional part is greater or equal than 0.5 (as it is in my example)!

What you COULD use is

CONCAT(REPLACE(FORMAT(FLOOR(number),0),',','.'),',',SUBSTRING_INDEX(FORMAT(number,2),'.',-1))

if your MySQL/MariaDB's FORMAT doesn't support "locale_name" (see MindStalker's post - Thx 4 that, pal). Note the FLOOR function I've added.

You can also watch the output like this:

final Process p = Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");

new Thread(new Runnable() {
    public void run() {
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line = null;

        try {
            while ((line = input.readLine()) != null)
                System.out.println(line);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}).start();

p.waitFor();

And don't forget, if you are running a windows command, you need to put cmd /c in front of your command.

EDIT: And for bonus points, you can also use ProcessBuilder to pass input to a program:

String[] command = new String[] {
        "choice",
        "/C",
        "YN",
        "/M",
        "\"Press Y if you're cool\""
};
String inputLine = "Y";

ProcessBuilder pb = new ProcessBuilder(command);
pb.redirectErrorStream(true);
Process p = pb.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));

writer.write(inputLine);
writer.newLine();
writer.close();

String line;

while ((line = reader.readLine()) != null) {
    System.out.println(line);
}

This will run the windows command choice /C YN /M "Press Y if you're cool" and respond with a Y. So, the output will be:

Press Y if you're cool [Y,N]?Y

Use the gca ("get current axes") helper function:

ax = plt.gca()

Example:

import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()

The inbuilt function abs() would do the trick.

positivenum = abs(negativenum)

Visual Studio 2015:

Project => Your Application Properties. Each argument can be separated using space. If you have a space in between for the same argument, put double quotes as shown in the example below.

        static void Main(string[] args)
        {
            if(args == null || args.Length == 0)
            {
                Console.WriteLine("Please specify arguments!");
            }
            else
            {
                Console.WriteLine(args[0]);     // First
                Console.WriteLine(args[1]);     // Second Argument
            }
        }

(This answer is from years ago, when it was the best answer. There is now a better answer below this. I haven't kept up with node.js, and I cannot delete this answer because it is marked "correct on this question". If you are thinking of down clicking, what do you want me to do?)

The key is to use the data and end events of a Readable Stream. Listen to these events:

stream.on('data', (chunk) => { ... });
stream.on('end', () => { ... });

When you receive the data event, add the new chunk of data to a Buffer created to collect the data.

When you receive the end event, convert the completed Buffer into a string, if necessary. Then do what you need to do with it.

I think you should append .value in IF statement:

If Cells(i, "A").Value <> "Miami" And Cells(i, "D").Value <> "Florida" Then
    Cells(i, "C").Value = "BA"
End IF

Ideally you should do both.

First Hash the pass password for the one way security. Use a salt for extra security.

Then encrypt the hash to defend against dictionary attacks if your database of password hashes is compromised.

A bit late, but perhaps someone will find it useful.

Links that fix the problem (you must be logged into google account):

https://security.google.com/settings/security/activity?hl=en&pli=1

https://www.google.com/settings/u/1/security/lesssecureapps

https://accounts.google.com/b/0/DisplayUnlockCaptcha

Some explanation of what happens:

This problem can be caused by either 'less secure' applications trying to use the email account (this is according to google help, not sure how they judge what is secure and what is not) OR if you are trying to login several time in a row OR if you change countries (for example use VPN, move code to different server or actually try to login from different part of the world).

To resolve I had to: (first time)

• login to my account via web
• view recent attempts to use the account and accept suspicious access: THIS LINK
• disable the feature of blocking suspicious apps/technologies: THIS LINK

This worked the first time, but few hours later, probably because I was doing a lot of testing the problem reappeared and was not fixable using the above method. In addition I had to clear the captcha (the funny picture, which asks you to rewrite a word or a sentence when logging into any account nowadays too many times) :

• after login to my account I went HERE
• Clicked continue

Hope this helps.

First to set group_concat_max_len, otherwise it will not give you all the result:

SET GLOBAL  group_concat_max_len = 999999;
SELECT GROUP_CONCAT(id)  FROM table_level where parent_id=4 group by parent_id;

Here is a basic example of how an image file with certain restrictions (listed below) can be uploaded to the server.

• Existence of the image.
• Image extension validation

• Checks for image size.

  <?php
     $newfilename = "newfilename";
  
     if(isset($_FILES['image'])){
        $errors= array();
        $file_name = $_FILES['image']['name'];
        $file_size =$_FILES['image']['size'];
        $file_tmp =$_FILES['image']['tmp_name'];
        $file_type=$_FILES['image']['type'];
        $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
  
        $expensions= array("jpeg","jpg","png");
        if(file_exists($file_name)) {
          echo "Sorry, file already exists.";
          }
        if(in_array($file_ext,$expensions)=== false){
           $errors[]="extension not allowed, please choose a JPEG or PNG file.";
        }
  
        if($file_size > 2097152){
           $errors[]='File size must be excately 2 MB';
        }
  
        if(empty($errors)==true){
          move_uploaded_file($file_tmp,"images/".$newfilename.".".$file_ext);
          echo "Success";
          echo "<script>window.close();</script>";
  
        }
  
        else{
           print_r($errors);
        }
     }
  ?>
  <html>
     <body>
  
        <form action="" method="POST" enctype="multipart/form-data">

Intent sendIntent = new Intent();

You can use the following steps:

Step 1: Create a requirements.txt with list of packages to be installed. If you want to copy packages in a particular environment, do this

pip freeze >> requirements.txt

else store package names in a file named requirements.txt

Step 2: Execute pip command with this file

pip install -r requirements.txt

For a small set of short strings (i.e. 2 or 3 strings of no more than a few characters), plus is still way faster. Using mkoistinen's wonderful script in Python 2 and 3:

plus 2.679107467004 (100.00% as fast)
join 3.653773699996 (73.32% as fast)
form 6.594011374000 (40.63% as fast)
intp 4.568015249999 (58.65% as fast)

So when your code is doing a huge number of separate small concatenations, plus is the preferred way if speed is crucial.

Try something like this:

foreach (ListItem listItem in clbIncludes.Items)
{
    if (listItem.Selected) { 
        //do some work 
    }
    else { 
        //do something else 
    }
}

Simply wrap the content using RecyclerView with the Grid Layout

Image: Recycler as GridView layout

Just use the GridLayoutManager like this:

RecyclerView.LayoutManager mRecyclerGrid=new GridLayoutManager(this,3,LinearLayoutManager.VERTICAL,false);
mRecyclerView.setLayoutManager(mRecyclerGrid);

You can set how many items should appear on a row (replace the 3).

If you want to align various items and you like to have same margin around all sides, you can use the following. Each element withing container, regardless of type, will receive the same surrounding margin.

.container {
  display: flex;
}
.container > * {
  margin: 5px;
}

If you wish to align items in a row, but have the first element touch the leftmost edge of container, and have all other elements be equally spaced, you can use this:

.container {
  display: flex;
}
.container > :first-child {
  margin-right: 5px;
}
.container > *:not(:first-child) {
  margin: 5px;
}

Look for assigning the output to Clipboard (in your first script) and then in second script parse Clipboard value.
