A alternative without glib dependency is pkg-config-lite.

Extract pkg-config.exe from the archive and put it in your path.

Nowdays this package is available using chocolatey, then it could be installed whith

choco install pkgconfiglite

I got the same error when trying to compile a Go package on Debian 9.8:

# pkg-config --cflags  -- libssl libcrypto
Package libssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libssl.pc'

The thing is that pkg-config searches for package meta-information in .pc files. Such files come from the dev package. So, even though I had libssl installed, I still got the error. It was resolved by running:

sudo apt-get install libssl-dev

If I'm reading this question correctly, you may be missing that a jQuery mobile "button" widget is not the same thing as an HTML button element. I think this boils down to you can't call $('input').button('disable') unless you have previously called $('input').button(); to initialize a jQuery Mobile button widget on your input.

Of course, you may not want to be using jQuery button widget functionality, in which case Alexander's answer should set you right.

I created a ~/.wgetrc file with the following content (obtained from askapache.com but with a newer user agent, because otherwise it didn’t work always):

header = Accept-Language: en-us,en;q=0.5
header = Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
header = Connection: keep-alive
user_agent = Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0
referer = /
robots = off

Now I’m able to download from most (all?) file-sharing (streaming video) sites.

The :active pseudo-class is not the same as adding a class to style the element.

The :active CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the mouse button is pressed down and ends when it is released.

What we are looking for is a class, such as .active, which we can use to style the navigation item.

For a clearer example of the difference between :active and .active see the following snippet:

li:active {_x000D_
  background-color: #35495E;_x000D_
}_x000D_
_x000D_
li.active {_x000D_
  background-color: #41B883;_x000D_
}

<ul>_x000D_
  <li>:active (pseudo-class) - Click me!</li>_x000D_
  <li class="active">.active (class)</li>_x000D_
</ul>

Vue-Router

vue-router automatically applies two active classes, .router-link-active and .router-link-exact-active, to the <router-link> component.

router-link-active

This class is applied automatically to the <router-link> component when its target route is matched.

The way this works is by using an inclusive match behavior. For example, <router-link to="/foo"> will get this class applied as long as the current path starts with /foo/ or is /foo.

So, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, both components would get the router-link-active class when the path is /foo/bar.

router-link-exact-active

This class is applied automatically to the <router-link> component when its target route is an exact match. Take into consideration that both classes, router-link-active and router-link-exact-active, will be applied to the component in this case.

Using the same example, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, the router-link-exact-activeclass would only be applied to <router-link to="/foo/bar"> when the path is /foo/bar.

The exact prop

Lets say we have <router-link to="/">, what will happen is that this component will be active for every route. This may not be something that we want, so we can use the exact prop like so: <router-link to="/" exact>. Now the component will only get the active class applied when it is an exact match at /.

CSS

We can use these classes to style our element, like so:

 nav li:hover,
 nav li.router-link-active,
 nav li.router-link-exact-active {
   background-color: indianred;
   cursor: pointer;
 }

The <router-link> tag was changed using the tag prop, <router-link tag="li" />.

Change default classes globally

If we wish to change the default classes provided by vue-router globally, we can do so by passing some options to the vue-router instance like so:

const router = new VueRouter({
  routes,
  linkActiveClass: "active",
  linkExactActiveClass: "exact-active",
})

Change default classes per component instance (<router-link>)

If instead we want to change the default classes per <router-link> and not globally, we can do so by using the active-class and exact-active-class attributes like so:

<router-link to="/foo" active-class="active">foo</router-link>

<router-link to="/bar" exact-active-class="exact-active">bar</router-link>

v-slot API

Vue Router 3.1.0+ offers low level customization through a scoped slot. This comes handy when we wish to style the wrapper element, like a list element <li>, but still keep the navigation logic in the anchor element <a>.

<router-link
  to="/foo"
  v-slot="{ href, route, navigate, isActive, isExactActive }"
>
  <li
    :class="[isActive && 'router-link-active', isExactActive && 'router-link-exact-active']"
  >
    <a :href="href" @click="navigate">{{ route.fullPath }}</a>
  </li>
</router-link>

You can use pandas.Series.map :

df['col'].map('str{}'.format)

It will apply the word "str" before all your values.

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

This is a simple solution:

Example 1

my $var1 = "123abc";
print $var1 + 0;

Result

123

Example 2

my $var2 = "abc123";
print $var2 + 0;

Result

0

I figured it out! Here's the details:

1. Add the main AutoMapper Package to your solution via NuGet.

2. Add the AutoMapper Dependency Injection Package to your solution via NuGet.

3. Create a new class for a mapping profile. (I made a class in the main solution directory called MappingProfile.cs and add the following code.) I'll use a User and UserDto object as an example.

    public class MappingProfile : Profile {
        public MappingProfile() {
            // Add as many of these lines as you need to map your objects
            CreateMap<User, UserDto>();
            CreateMap<UserDto, User>();
        }
    }
   

4. Then add the AutoMapperConfiguration in the Startup.cs as shown below:

    public void ConfigureServices(IServiceCollection services) {
        // .... Ignore code before this
   
       // Auto Mapper Configurations
        var mapperConfig = new MapperConfiguration(mc =>
        {
            mc.AddProfile(new MappingProfile());
        });
   
        IMapper mapper = mapperConfig.CreateMapper();
        services.AddSingleton(mapper);
   
        services.AddMvc();
   
    }
   

5. To invoke the mapped object in code, do something like the following:

    public class UserController : Controller {
   
        // Create a field to store the mapper object
        private readonly IMapper _mapper;
   
        // Assign the object in the constructor for dependency injection
        public UserController(IMapper mapper) {
            _mapper = mapper;
        }
   
        public async Task<IActionResult> Edit(string id) {
   
            // Instantiate source object
            // (Get it from the database or whatever your code calls for)
            var user = await _context.Users
                .SingleOrDefaultAsync(u => u.Id == id);
   
            // Instantiate the mapped data transfer object
            // using the mapper you stored in the private field.
            // The type of the source object is the first type argument
            // and the type of the destination is the second.
            // Pass the source object you just instantiated above
            // as the argument to the _mapper.Map<>() method.
            var model = _mapper.Map<UserDto>(user);
   
            // .... Do whatever you want after that!
        }
    }
   

I hope this helps someone starting fresh with ASP.NET Core! I welcome any feedback or criticisms as I'm still new to the .NET world!

Set also android:gravity parameter in TextView to center.

For testing the effects of different layout parameters I recommend to use different background color for every element, so you can see how your layout changes with parameters like gravity, layout_gravity or others.

execute below

Python manage.py makemigrations

It will show missing package.

Install missing package and again run below command to make sure if nothing is missed.

Python manage.py makemigrations

It will resolve your issue.

For me, this error came up when I was trying to rollback a transaction block after encountering an exception, inside another transaction block.

All I had to do to fix it was to remove my inner transaction block.

Things can get quite messy when using nested transactions, best to avoid this and just restructure your code.

Separate function to make adding event handlers much easier.

function addListener(event, obj, fn) {
    if (obj.addEventListener) {
        obj.addEventListener(event, fn, false);   // modern browsers
    } else {
        obj.attachEvent("on"+event, fn);          // older versions of IE
    }
}

element = document.getElementsByClassName('drill_cursor')[0];

addListener('click', element, function () {
    // Do stuff
});

The Main method is Static. You can not invoke a non-static method from a static method.

GetRandomBits()

is not a static method. Either you have to create an instance of Program

Program p = new Program();
p.GetRandomBits();

or make

GetRandomBits() static.

When you want to trigger javascript code from an anchor tag, the onclick handler should be used rather than the javascript: pseudo-protocol. The javascript code that runs within the onclick handler must return true or false (or an expression than evalues to true or false) back to the tag itself - if it returns true, then the HREF of the anchor will be followed like a normal link. If it returns false, then the HREF will be ignored. This is why "return false;" is often included at the end of the code within an onclick handler.

Here is a more generalized solution that prints all elements of x the vector x in this format:

x=randperm(3);
s = repmat('%d,',1,length(x));
s(end)=[]; %Remove trailing comma

disp(sprintf(['Answer: (' s ')'], x))

in visualstudio 2008 you could use this code :

   var _assembly = System.Reflection.Assembly
               .GetExecutingAssembly().GetName().CodeBase;

   var _path = System.IO.Path.GetDirectoryName(_assembly) ;

To install it, just run the command

npm install jquery

or

yarn add jquery

then you can import it in your file like

import $ from 'jquery';

private makes the class accessible only to the class in which it is declared. If we make entire class private no one from outside can access the class and makes it useless.

Inner class can be made private because the outer class can access inner class where as it is not the case with if you make outer class private.

//white background
canvas.drawRGB(255, 255, 255);
//border's properties
paint.setColor(Color.BLACK);
paint.setStrokeWidth(0);        
paint.setStyle(Paint.Style.STROKE);         
canvas.drawRect(100, 100, 200, 200, paint);

The reason being you can not access protected member data through the instance of the class.

Reason why it is not allowed is explained in this blog

System Preferences => Keyboard => Key Repeat Rate

This doesn't show the window:

Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
cmd.StartInfo.CreateNoWindow = true;

...
cmd.Start();

I know this is an old question, but it took me some time to sort this out given the sparse Angular documentation. The RouteProvider and routeParams is the way to go. The route wires up the URL to your Controller/View and the routeParams can be passed into the controller.

Check out the Angular seed project. Within the app.js you'll find an example for the route provider. To use params simply append them like this:

$routeProvider.when('/view1/:param1/:param2', {
    templateUrl: 'partials/partial1.html',    
    controller: 'MyCtrl1'
});

Then in your controller inject $routeParams:

.controller('MyCtrl1', ['$scope','$routeParams', function($scope, $routeParams) {
  var param1 = $routeParams.param1;
  var param2 = $routeParams.param2;
  ...
}]);

With this approach you can use params with a url such as: "http://www.example.com/view1/param1/param2"

Since this thread has bumped up, I have compiled few points for readers new to this topic.

How is the value of this determined?

We use this similar to the way we use pronouns in natural languages like English: “John is running fast because he is trying to catch the train.” Instead we could have written “… John is trying to catch the train”.

var person = {    
    firstName: "Penelope",
    lastName: "Barrymore",
    fullName: function () {

    // We use "this" just as in the sentence above:
       console.log(this.firstName + " " + this.lastName);

    // We could have also written:
       console.log(person.firstName + " " + person.lastName);
    }
}

this is not assigned a value until an object invokes the function where it is defined. In the global scope, all global variables and functions are defined on the window object. Therefore, this in a global function refers to (and has the value of) the global window object.

When use strict, this in global and in anonymous functions that are not bound to any object holds a value of undefined.

The this keyword is most misunderstood when: 1) we borrow a method that uses this, 2) we assign a method that uses this to a variable, 3) a function that uses this is passed as a callback function, and 4) this is used inside a closure — an inner function. ⁽²⁾

What holds the future

Defined in ECMA Script 6, arrow-functions adopt the this binding from the enclosing (function or global) scope.

function foo() {
     // return an arrow function
     return (a) => {
     // `this` here is lexically inherited from `foo()`
     console.log(this.a);
  };
}
var obj1 = { a: 2 };
var obj2 = { a: 3 };

var bar = foo.call(obj1);
bar.call( obj2 ); // 2, not 3!

While arrow-functions provide an alternative to using bind(), it’s important to note that they essentially are disabling the traditional this mechanism in favor of more widely understood lexical scoping. ⁽¹⁾

For current datetime, you can use now() function in postgresql insert query.

You can also refer following link.

insert statement in postgres for data type timestamp without time zone NOT NULL,.

Set your header and footer position to "absolute" and that should do the trick. Hope it helps and good luck with your project!

@Davy Ladman your solution with shift are corrent but only for ip starting with number less or equal 99, infact first octect must be cast up to long.

Anyway convert back with long type is quite difficult because store 64 bit (not 32 for Ip) and fill 4 bytes with zeroes

static uint ToInt(string addr)
{
   return BitConverter.ToUInt32(IPAddress.Parse(addr).GetAddressBytes(), 0);
}

static string ToAddr(uint address)
{
    return new IPAddress(address).ToString();
}

Enjoy!

If you want to export all JAR-files of a Java web-project, open the latest generated WAR-file with a ZIP-tool (e.g. 7-Zip), navigate to the /WEB-INF/lib/ folder. Here you will find all JAR-files you need for this project (as listed in "Referenced Libraries").

Im going to provide an argument against using socket.io.

I think using socket.io solely because it has fallbacks isnt a good idea. Let IE8 RIP.

In the past there have been many cases where new versions of NodeJS has broken socket.io. You can check these lists for examples... https://github.com/socketio/socket.io/issues?q=install+error

If you go to develop an Android app or something that needs to work with your existing app, you would probably be okay working with WS right away, socket.io might give you some trouble there...

Plus the WS module for Node.JS is amazingly simple to use.

Try with pip3:

sudo pip3 install pycrypto

You can use the Task Parallel Library. To be more exact, you can use Task.Wait(TimeSpan):

using System.Threading.Tasks;

var task = Task.Run(() => SomeMethod(input));
if (task.Wait(TimeSpan.FromSeconds(10)))
    return task.Result;
else
    throw new Exception("Timed out");

Since when the edit is complete the focus from the element is always lost you could simply use the onBlur hook.

<div onBlur={(e)=>{console.log(e.currentTarget.textContent)}} contentEditable suppressContentEditableWarning={true}>
     <p>Lorem ipsum dolor.</p>
</div>

Here's a bit of JavaScript and jQuery I threw together to wrap the first word of each paragraph with a <span> tag.

$(function() {
    $('#content p').each(function() {
        var text = this.innerHTML;
        var firstSpaceIndex = text.indexOf(" ");
        if (firstSpaceIndex > 0) {
            var substrBefore = text.substring(0,firstSpaceIndex);
            var substrAfter = text.substring(firstSpaceIndex, text.length)
            var newText = '<span class="firstWord">' + substrBefore + '</span>' + substrAfter;
            this.innerHTML = newText;
        } else {
            this.innerHTML = '<span class="firstWord">' + text + '</span>';
        }
    });
});

You can then use CSS to create a style for .firstWord.

It's not perfect, as it doesn't account for every type of whitespace; however, I'm sure it could accomplish what you're after with a few tweaks.

Keep in mind that this code will only execute after page load, so it may take a split second to see the effect.

To make it easier for yourself you could also create an actionfilterattribute

public class AllowJsonGetAttribute : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var jsonResult = filterContext.Result as JsonResult;

        if (jsonResult == null)
            throw new ArgumentException("Action does not return a JsonResult, 
                                                   attribute AllowJsonGet is not allowed");

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;            

        base.OnResultExecuting(filterContext);
    }
}

and use it on your action

[AllowJsonGet]
public JsonResult MyAjaxAction()
{
    return Json("this is my test");
}

The easiest way is to use LINQ's Union method:

var aUb = A.Union(B).ToList();

os.chdir(r"D:\Folder1\Folder2")
os.rename(src,dst)
#src and dst should be inside Folder2

You can add and remove classes with jQuery like so:

$(".first").addClass("second")
// remove a class
$(".first").removeClass("second")

By the way you can set multiple classes in your markup right away separated with a whitespace

<div class="second first"></div>

To enable Api do this

1. Go to API Manager
2. Click on Overview
3. Search for Google Maps JavaScript API(Under Google Maps APIs). Click on that
4. You will find Enable button there. Click to enable API.

OR You can try this url: Maps JavaScript API

Hope this will solve the problem of enabling API.

You can also use below just simple to check:

If startDate <> Nothing Then
your logic
End If

It will check that the startDate variable of DateTime datatype is null or not.

You could make the variables public fields:

  public int width;
  public int height;

  DrawFrame() {
    this.width = 400;
    this.height = 400;
  }

You could then access the variables like so:

DrawFrame frame = new DrawFrame();
int theWidth = frame.width;
int theHeight = frame.height;

A better solution, however, would be to make the variables private fields add two accessor methods to your class, keeping the data in the DrawFrame class encapsulated:

 private int width;
 private int height;

 DrawFrame() {
    this.width = 400;
    this.height = 400;
 }

  public int getWidth() {
     return this.width;
  }

  public int getHeight() {
     return this.height;
  }

Then you can get the width/height like so:

  DrawFrame frame = new DrawFrame();
  int theWidth = frame.getWidth();
  int theHeight = frame.getHeight();

I strongly suggest you use the latter method.

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

/#$/.test(str)

will work on all browsers, doesn't require monkey patching String, and doesn't require scanning the entire string as lastIndexOf does when there is no match.

If you want to match a constant string that might contain regular expression special characters, such as '$', then you can use the following:

function makeSuffixRegExp(suffix, caseInsensitive) {
  return new RegExp(
      String(suffix).replace(/[$%()*+.?\[\\\]{|}]/g, "\\$&") + "$",
      caseInsensitive ? "i" : "");
}

and then you can use it like this

makeSuffixRegExp("a[complicated]*suffix*").test(str)

The key difference between a builder and factory IMHO, is that a builder is useful when you need to do lots of things to build an object. For example imagine a DOM. You have to create plenty of nodes and attributes to get your final object. A factory is used when the factory can easily create the entire object within one method call.

One example of using a builder is a building an XML document, I've used this model when building HTML fragments for example I might have a Builder for building a specific type of table and it might have the following methods (parameters are not shown):

BuildOrderHeaderRow()
BuildLineItemSubHeaderRow()
BuildOrderRow()
BuildLineItemSubRow()

This builder would then spit out the HTML for me. This is much easier to read than walking through a large procedural method.

Check out Builder Pattern on Wikipedia.

Maybe someone will find it useful. I wanted to stay independent from X clipboard, and still be able to copy and paste some text between two running vims. This little code save the selected text in temp.txt file for copying. Put the code below into your .vimrc. Use CTRL-c CTRL-v to do the job.

vnoremap :w !cp /dev/null ~/temp.txt && cat > ~/temp.txt

noremap :r !cat ~/temp.txt

Use dev.new(). (See this related question.)

plot(1:10)
dev.new(width=5, height=4)
plot(1:20)

To be more specific which units are used:

dev.new(width=5, height=4, unit="in")
plot(1:20)
dev.new(width = 550, height = 330, unit = "px")
plot(1:15)

edit additional argument for Rstudio (May 2020), (thanks user Soren Havelund Welling)

For Rstudio, add dev.new(width=5,height=4,noRStudioGD = TRUE)

Your first suggestion works for me

from IPython.display import display, Image
display(Image(filename='path/to/image.jpg'))

If you are looking to handle the thousands separator, you should really use toLocaleString() from the JavaScript Number class since it will format the string for the user's region.

The JavaScript Date class can format localized dates and times.

Starting Git 2.0.1 (June 25th, 2014), a git mv will just work on a case insensitive OS.

See commit baa37bf by David Turner (dturner-tw).

mv: allow renaming to fix case on case insensitive filesystems

"git mv hello.txt Hello.txt" on a case insensitive filesystem always triggers "destination already exists" error, because these two names refer to the same path from the filesystem's point of view and requires the user to give "--force" when correcting the case of the path recorded in the index and in the next commit.

Detect this case and allow it without requiring "--force".

git mv hello.txt Hello.txt just works (no --force required anymore).

The other alternative is:

git config --global core.ignorecase false

And rename the file directly; git add and commit.

Everything in python is considered as object so functions are also objects. So you can use this method as well.

def fun1():
    fun1.var = 100
    print(fun1.var)

def fun2():
    print(fun1.var)

fun1()
fun2()

print(fun1.var)

For the second part of your question, you can also use shift, for example:

df['t-1'] = df['t'].shift(1)

t-1 would then contain the values from t one row above.

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.shift.html

One can simply retrieve view object as mentioned below

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

View view = DataBindingUtil.inflate(inflater, R.layout.layout_file, container, false).getRoot();

return view;

}

raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], format='%d%b%Y:%H:%M:%S.%f')

works, however it results in a Python warning of A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead

I would guess this is due to some chaining indexing.

Without the 0b in front:

"{0:b}".format(int)

Starting with Python 3.6 you can also use formatted string literal or f-string, --- PEP:

f"{int:b}"

This target can achieve through different method,

1. Using BaseController

The way I like to set things up, I make a BaseController class that extends Laravel’s own Controller, and set up various global things there. All other controllers then extend from BaseController rather than Laravel’s Controller.

class BaseController extends Controller
{
  public function __construct()
  {
    //its just a dummy data object.
    $user = User::all();

    // Sharing is caring
    View::share('user', $user);
  }
}

2. Using Filter

If you know for a fact that you want something set up for views on every request throughout the entire application, you can also do it via a filter that runs before the request — this is how I deal with the User object in Laravel.

App::before(function($request)
{
  // Set up global user object for views
  View::share('user', User::all());
});

OR

You can define your own filter

Route::filter('user-filter', function() {
    View::share('user', User::all());
});

and call it through simple filter calling.

Update According to Version 5.*

3. Using Middleware

Using the View::share with middleware

Route::group(['middleware' => 'SomeMiddleware'], function(){
  // routes
});



class SomeMiddleware {
  public function handle($request)
  {
    \View::share('user', auth()->user());
  }

4. Using View Composer

View Composer also help to bind specific data to view in different ways. You can directly bind variable to specific view or to all views. For Example you can create your own directory to store your view composer file according to requirement. and these view composer file through Service provide interact with view.

View composer method can use different way, First example can look alike:

You could create an App\Http\ViewComposers directory.

Service Provider

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("ViewName","App\Http\ViewComposers\TestViewComposer");
    }
}

After that, add this provider to config/app.php under "providers" section.

TestViewComposer

namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;

class TestViewComposer {

    public function compose(View $view) {
        $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
    }
}

ViewName.blade.php

Here you are... {{$ViewComposerTestVariable}}

This method could help for only specific View. But if you want trigger ViewComposer to all views, we have to apply this single change to ServiceProvider.

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer('*',"App\Http\ViewComposers\TestViewComposer");
    }
}

Laravel Documentation

For Further Clarification Laracast Episode

If still something unclear from my side, let me know.

Since Symfony 3.3 you can use binding, like

services:
_defaults:
    autowire: true      
    autoconfigure: true
    bind:
        $kernelProjectDir: '%kernel.project_dir%'

After that you can use parameter $kernelProjectDir in any controller OR service. Just like

class SomeControllerOrService
{
    public function someAction(...., $kernelProjectDir)
    {
          .....

You just need Visual C++ runtime 2015 installed, if you change your php version to the newest version you will get the error for it. this is why apache has php dependency error.

Use:

function getvalues(){
var inps = document.getElementsByName('pname[]');
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
    alert("pname["+i+"].value="+inp.value);
}
}

Here is Demo.

Want HEAD detached mode?

If you wish to rollback X time to a certain commit with a DETACHED HEAD (meaning you can't mess up anything), then by all means, use the following:

(replace X with how many commits you wish to go back)

git checkout HEAD~X

I.E. to go back one commit:

git checkout HEAD~1

SET TERMOUT

SET TERMOUT OFF suppresses the display so that you can spool output from a script without seeing it on the screen.

If both spooling to file and writing to terminal are not required, use SET TERMOUT OFF in >SQL scripts to disable terminal output.

Why don't you try sudo with the H flag? This should do the trick.

sudo -H pip install flake8

A regular sudo pip install flake8 will try to use your own home directory. The -H instructs it to use the system's home directory. More info at https://stackoverflow.com/a/43623102/

As of PHP 5.5, PHP has simple, secure functions for hashing and verifying passwords, password_hash() and password_verify()

$password = 'anna';
$hash = password_hash($password, PASSWORD_DEFAULT);
$expensiveHash = password_hash($password, PASSWORD_DEFAULT, array('cost' => 20));

password_verify('anna', $hash); //Returns true
password_verify('anna', $expensiveHash); //Also returns true
password_verify('elsa', $hash); //Returns false

When password_hash() is used, it generates a random salt and includes it in the outputted hash (along with the the cost and algorithm used.) password_verify() then reads that hash and determines the salt and encryption method used, and verifies it against the provided plaintext password.

Providing the PASSWORD_DEFAULT instructs PHP to use the default hashing algorithm of the installed version of PHP. Exactly which algorithm that means is intended to change over time in future versions, so that it will always be one of the strongest available algorithms.

Increasing cost (which defaults to 10) makes the hash harder to brute-force but also means generating hashes and verifying passwords against them will be more work for your server's CPU.

Note that even though the default hashing algorithm may change, old hashes will continue to verify just fine because the algorithm used is stored in the hash and password_verify() picks up on it.

Give Safe User Permission To Use Port 80

Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/

Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port - where port number > 1024.

A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:

sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

Now, when you tell a Node application that you want it to run on port 80, it will not complain.

Lower your gulp version in package.json file to 3.9.1-

This is what I use, but it is slow on large text files.

get-content $pathToFile | % { $_ -replace $stringToReplace, $replaceWith } | set-content $pathToFile

If you are going to be replacing strings in large text files and speed is a concern, look into using System.IO.StreamReader and System.IO.StreamWriter.

try
{
   $reader = [System.IO.StreamReader] $pathToFile
   $data = $reader.ReadToEnd()
   $reader.close()
}
finally
{
   if ($reader -ne $null)
   {
       $reader.dispose()
   }
}

$data = $data -replace $stringToReplace, $replaceWith

try
{
   $writer = [System.IO.StreamWriter] $pathToFile
   $writer.write($data)
   $writer.close()
}
finally
{
   if ($writer -ne $null)
   {
       $writer.dispose()
   }
}

(The code above has not been tested.)

There is probably a more elegant way to use StreamReader and StreamWriter for replacing text in a document, but that should give you a good starting point.

"o" format is different for DateTime vs DateTimeOffset :(

DateTime.UtcNow.ToString("o") -> "2016-03-09T03:30:25.1263499Z"

DateTimeOffset.UtcNow.ToString("o") -> "2016-03-09T03:30:46.7775027+00:00"

My final answer is

DateTimeOffset.UtcDateTime.ToString("o")   //for DateTimeOffset type
DateTime.UtcNow.ToString("o")              //for DateTime type

I think this gives you the total list of all files in the repo history:

git rev-list --objects --all | git cat-file --batch-check="%(objectsize) %(rest)" | cut -d" " -f1 | paste -s -d + - | bc

You can replace --all with a treeish (HEAD, origin/master, etc.) to calculate the size of a branch.

Attempt 2 was close to perfect. Just modify it slightly:

RewriteEngine On
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

This thread seems unnecessarily controversial.

If you really want to solve this question correctly, using jQuery, please see the solution below.

The question is "jQuery How do you get an image to fade in on load?"

First, a quick note.

This is not a good candidate for $(document).ready...

Why? Because the document is ready when the HTML DOM is loaded. The logo image will not be ready at this point - it may still be downloading in fact!

So to answer first the general question "jQuery How do you get an image to fade in on load?" - the image in this example has an id="logo" attribute:

$("#logo").bind("load", function () { $(this).fadeIn(); });

This does exactly what the question asks. When the image has loaded, it will fade in. If you change the source of the image, when the new source has loaded, it will fade in.

There is a comment about using window.onload alongside jQuery. This is perfectly possible. It works. It can be done. However, the window.onload event needs a particular bit of care. This is because if you use it more than once, you overwrite your previous events. Example (feel free to try it...).

function SaySomething(words) {
    alert(words);
}
window.onload = function () { SaySomething("Hello"); };
window.onload = function () { SaySomething("Everyone"); };
window.onload = function () { SaySomething("Oh!"); };

Of course, you wouldn't have three onload events so close together in your code. You would most likely have a script that does something onload, and then add your window.onload handler to fade in your image - "why has my slide show stopped working!!?" - because of the window.onload problem.

One great feature of jQuery is that when you bind events using jQuery, they ALL get added.

So there you have it - the question has already been marked as answered, but the answer seems to be insufficient based on all the comments. I hope this helps anyone arriving from the world's search engines!

What would be useful here would be a LIKE ANY predicate as is available in PostgreSQL

SELECT * 
FROM tbl
WHERE my_col LIKE ANY (ARRAY['%val1%', '%val2%', '%val3%', ...])

Unfortunately, that syntax is not available in Oracle. You can expand the quantified comparison predicate using OR, however:

SELECT * 
FROM tbl
WHERE my_col LIKE '%val1%' OR my_col LIKE '%val2%' OR my_col LIKE '%val3%', ...

Or alternatively, create a semi join using an EXISTS predicate and an auxiliary array data structure (see this question for details):

SELECT *
FROM tbl t
WHERE EXISTS (
  SELECT 1
  -- Alternatively, store those values in a temp table:
  FROM TABLE (sys.ora_mining_varchar2_nt('%val1%', '%val2%', '%val3%'/*, ...*/))
  WHERE t.my_col LIKE column_value
)

For true full-text search, you might want to look at Oracle Text: http://www.oracle.com/technetwork/database/enterprise-edition/index-098492.html

functional requirements are the main things that the user expects from the software for example if the application is a banking application that application should be able to create a new account, update the account, delete an account, etc. functional requirements are detailed and are specified in the system design

Non-functional requirement are not straight forward the requirement of the system rather it is related to usability( in some way ) for example for a banking application a major non-functional requirement will be available the application should be available 24/7 with no downtime if possible.

   buildscript { repositories { jcenter() mavenCentral() maven { url 'https://maven.google.com/' name 'Google' } google() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' } } allprojects { repositories { jcenter() google() } }

In order to remove a row from a JTable, you need to remove the target row from the underlying TableModel. If, for instance, your TableModel is an instance of DefaultTableModel, you can remove a row by doing the following:

((DefaultTableModel)myJTable.getModel()).removeRow(rowToRemove);

Why so complicated? just put this :

data-html='true'

Use is_null or === operator.

is_null($result['column'])

$result['column'] === NULL

Concise if you are just interested in the time elapsed that is under 24 hours. You can format the output as needed in the return statement :

import datetime
def elapsed_interval(start,end):
    elapsed = end - start
    min,secs=divmod(elapsed.days * 86400 + elapsed.seconds, 60)
    hour, minutes = divmod(min, 60)
    return '%.2d:%.2d:%.2d' % (hour,minutes,secs)

if __name__ == '__main__':
    time_start=datetime.datetime.now()
    """ do your process """
    time_end=datetime.datetime.now()
    total_time=elapsed_interval(time_start,time_end)

Try this

$('.slidingDiv').toggle("slide", {direction: "right" }, 1000);

I apologise for replying to a super old question but after spending an hour wrestling with the above solutions I opted for simpler stuff.

<script src=".." one="1" two="2"></script>

Inside above script:

document.currentScript.getAttribute('one'); //1
document.currentScript.getAttribute('two'); //2

Much easier than jquery OR url parsing.

You might need the polyfil for doucment.currentScript from @Yared Rodriguez's answer for IE:

document.currentScript = document.currentScript || (function() {
  var scripts = document.getElementsByTagName('script');
  return scripts[scripts.length - 1];
})();

From the Project Explorer, expand the project you want to hook up to a remote site (or just right click and create a new Web project that's empty if you just want to explore a remote site from there). There's a "Connections" node, right click it and select "Add New connection...". A dialog will appear, at bottom you can select the destination as Remote and then click the "New..." button. There you can set up an FTP/FTPS/SFTP connection.

That's how you set up a connection that's tied to a project, typically for upload/download/sync between it and a project.

You can also do Window > Show View > Remote. From that view, you can click the globe icon in the upper right to add connections and in this view you can just browse your remote connections.

Try this one:

class test {
     public function newTest(){
          $this->bigTest();
          $this->smallTest();
     }

     private function bigTest(){
          //Big Test Here
     }

     private function smallTest(){
          //Small Test Here
     }

     public function scoreTest(){
          //Scoring code here;
     }
}

$testObject = new test();

$testObject->newTest();

$testObject->scoreTest();

Not the best way, but at lease does not need external tools (except grep, which is standard on *nix boxes anyway)

sqlite3 database.db3 .dump | grep '^INSERT INTO "tablename"'

but you do need to do this command for each table you are looking for though.

Note that this does not include schema.

There are multiple reasons for this error.

One of the reason where i encountered this error is while building for linux and windows.

I have a filename with caps BaseClass.h SubClass.h Unix maintains has case-sensitive filenaming convention and windows is case-insensitive.

C++ why people don't use uppercase in name of header files?

Try compiling clean build using gmake clean if you are using gmake

Some text editors has default settings to ignore case-sensitive filenames. This could also lead to the same error.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

Definitely a late answer to this question. One possibility is to use the ListIterator in a for loop. It's not as clean as colon-syntax, but it works.

List<String> exampleList = new ArrayList<>();
exampleList.add("One");
exampleList.add("Two");
exampleList.add("Three");

//Forward iteration
for (String currentString : exampleList) {
    System.out.println(currentString); 
}

//Reverse iteration
for (ListIterator<String> itr = exampleList.listIterator(exampleList.size()); itr.hasPrevious(); /*no-op*/ ) {
    String currentString = itr.previous();
    System.out.println(currentString); 
}

Credit for the ListIterator syntax goes to "Ways to iterate over a list in Java"

I'm a bit reluctant to suggest UDP when TCP could possibly work. The problem is that if TCP isn't working for some reason, because the connection is too laggy or congested, changing the application to use UDP is unlikely to help. A bad connection is bad for UDP too. TCP already does a very good job of minimizing congestion.

The only case I can think of where UDP is required is for broadcast protocols. In cases where an application involves two, known hosts, UDP will likely only offer marginal performance benefits for substantially increased costs of code complexity.

Simple-read but precise solution would be:

func nowAsUnixMilliseconds(){
    return time.Now().Round(time.Millisecond).UnixNano() / 1e6
}

This function:

1. Correctly rounds the value to the nearest millisecond (compare with integer division: it just discards decimal part of the resulting value);
2. Does not dive into Go-specifics of time.Duration coercion — since it uses a numerical constant that represents absolute millisecond/nanosecond divider.

P.S. I've run benchmarks with constant and composite dividers, they showed almost no difference, so feel free to use more readable or more language-strict solution.

Just add the parameter "origin" with the URL of your site in the paramVars attribute of the player, like this:

this.player = new window['YT'].Player('player', {
    videoId: this.mediaid,
    width: '100%',
    playerVars: { 
        'autoplay': 1,
        'controls': 0,
        'autohide': 1,
        'wmode': 'opaque',
        'origin': 'http://localhost:8100' 
    },
}

I think you will have fewer problems if you declared a Property that implements INotifyPropertyChanged, then databind IsChecked, SelectedIndex(using IValueConverter) and Fill(using IValueConverter) to it instead of using the Checked Event to toggle SelectedIndex and Fill.

Before MySQL 5.6 Full-Text Search is supported only with MyISAM Engine.

Therefore either change the engine for your table to MyISAM

CREATE TABLE gamemech_chat (
  id bigint(20) unsigned NOT NULL auto_increment,
  from_userid varchar(50) NOT NULL default '0',
  to_userid varchar(50) NOT NULL default '0',
  text text NOT NULL,
  systemtext text NOT NULL,
  timestamp datetime NOT NULL default '0000-00-00 00:00:00',
  chatroom bigint(20) NOT NULL default '0',
  PRIMARY KEY  (id),
  KEY from_userid (from_userid),
  FULLTEXT KEY from_userid_2 (from_userid),
  KEY chatroom (chatroom),
  KEY timestamp (timestamp)
) ENGINE=MyISAM;

Here is SQLFiddle demo

Code sample:

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("colBestBefore", typeof(DateTime)));
dt.Columns.Add(new DataColumn("colStatus", typeof(string)));

dt.Columns["colStatus"].Expression = String.Format("IIF(colBestBefore < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

dt.Rows.Add(DateTime.Now.AddDays(-1));
dt.Rows.Add(DateTime.Now.AddDays(1));
dt.Rows.Add(DateTime.Now.AddDays(2));
dt.Rows.Add(DateTime.Now.AddDays(-2));

demoGridView.DataSource = dt;

UPDATE #2

dt.Columns["colStatus"].Expression = String.Format("IIF(CONVERT(colBestBefore, 'System.DateTime') < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

private DummyUser[] arrDummyUser = new DummyUser[]
{
    new DummyUser{
       email = "[email protected]",
       language = "English"
    },
    new DummyUser{

    }
}


<iframe id="theiframe" src="youriframe.html" style="width: 100px; height: 100px;" onload="iframeclick()"></iframe>

I was going to use clipboard.js, but it doesn't have any mobile solution in place (yet) ... so I wrote a super small library:

Cheval

This will either copy the text (desktop, Android, and Safari 10+), or at the very least, select the text (older versions of iOS). Minified it is just over 1 kB. In desktop Safari (before version 10) it tells the user to "Press Command + C to copy". You also don't need to write any JavaScript to use it.

LLVM is basically a library used to build compilers and/or language oriented software. The basic gist is although you have gcc which is probably the most common suite of compilers, it is not built to be re-usable ie. it is difficult to take components from gcc and use it to build your own application. LLVM addresses this issue well by building a set of "modular and reusable compiler and toolchain technologies" which anyone could use to build compilers and language oriented software.

The problem is that once the IsUserNameFocused is set to true, it will never be false. This solves it by handling the GotFocus and LostFocus for the FrameworkElement.

When creating a JQuery Dialog window, JQuery inserts a ui-widget-overlay class. If you bind a click function to that class to close the dialog, it should provide the functionality you are looking for.

Code will be something like this (untested):

$('.ui-widget-overlay').click(function() { $("#dialog").dialog("close"); });

Edit: The following has been tested for Kendo as well:

$('.k-overlay').click(function () {
            var popup = $("#dialogId").data("kendoWindow");
            if (popup)
                popup.close();
        });

I've found this question by trying to change the Log output of the DataContext to the output window. So to anyone else trying to do the same, what I've done was create this:

class DebugTextWriter : System.IO.TextWriter {
   public override void Write(char[] buffer, int index, int count) {
       System.Diagnostics.Debug.Write(new String(buffer, index, count));
   }

   public override void Write(string value) {
       System.Diagnostics.Debug.Write(value);
   }

   public override Encoding Encoding {
       get { return System.Text.Encoding.Default; }
   }
}

Annd after that: dc.Log = new DebugTextWriter() and I can see all the queries in the output window (dc is the DataContext).

Have a look at this for more info: http://damieng.com/blog/2008/07/30/linq-to-sql-log-to-debug-window-file-memory-or-multiple-writers

Well, no. Why there should be? Just discard the string if you don't need it anymore.

&str is more useful than String when you need to only read a string, because it is only a view into the original piece of data, not its owner. You can pass it around more easily than String, and it is copyable, so it is not consumed by the invoked methods. In this regard it is more general: if you have a String, you can pass it to where an &str is expected, but if you have &str, you can only pass it to functions expecting String if you make a new allocation.

You can find more on the differences between these two and when to use them in the official strings guide.

If you're dividing positive integers you can shift it up, do the division and then check the bit to the right of the real b0. In other words, 100/8 is 12.5 but would return 12. If you do (100<<1)/8, you can check b0 and then round up after you shift the result back down.

Merge - HEAD branch will generate a new commit, preserving the ancestry of each commit history. History can become polluted if merge commits are made by multiple people who work on the same branch in parallel.

Rebase - Re-writes the changes of one branch onto another without creating a new commit. The code history is simplified, linear and readable but it doesn't work with pull requests, because you can't see what minor changes someone made.

I would use git merge when dealing with feature-based workflow or if I am not familiar with rebase. But, if I want a more a clean, linear history then git rebase is more appropriate. For more details be sure to check out this merge or rebase article.

Or you can use unescapeHtml4:

    String miCadena="GUÍA TELEFÓNICA";
    System.out.println(StringEscapeUtils.unescapeHtml4(miCadena));

This code print the line: GUÍA TELEFÓNICA

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

mandatory parts:

tbody {
    overflow-y: scroll;  (could be: 'overflow: scroll' for the two axes)
    display: block;
    with: xxx (a number or 100%)
}

thead {
    display: inline-block;
}

Use the javascript Date object.

$(document).ready(function()  {
    $('#calendar').datepicker({
      dateFormat: 'yy-m-d',
      inline: true,
      onSelect: function(dateText, inst) { 
            var date = new Date(dateText);
            // change date.GetDay() to date.GetDate()
            alert(date.getDate() + date.getMonth() + date.getFullYear());
     } 
    });
});

There is no Pair in the standard framework, but the Apache Commons Lang, which comes quite close to “standard”, has a Pair.

Here's a trick to easily check if the schema already exists, and then create it, in it's own batch, to avoid the error message of trying to create a schema when it's not the only command in a batch.

IF NOT EXISTS (SELECT schema_name 
    FROM information_schema.schemata 
    WHERE schema_name = 'newSchemaName' )
BEGIN
    EXEC sp_executesql N'CREATE SCHEMA NewSchemaName;';
END

The best way I can think of to answer this is to make a custom jquery plugin to do this:

jQuery.fn.getIdArray = function() {
  var ret = [];
  $('[id]', this).each(function() {
    ret.push(this.id);
  });
  return ret;
};

Then do something like

var array = $("#mydiv").getIdArray();

The cor function will use the columns of the matrix in the calculation of correlation. So, the number of rows must be the same between your matrix x and matrix y. Ex.:

set.seed(1)
x <- matrix(rnorm(20), nrow=5, ncol=4)
y <- matrix(rnorm(15), nrow=5, ncol=3)
COR <- cor(x,y)
COR
image(x=seq(dim(x)[2]), y=seq(dim(y)[2]), z=COR, xlab="x column", ylab="y column")
text(expand.grid(x=seq(dim(x)[2]), y=seq(dim(y)[2])), labels=round(c(COR),2))

Edit:

Here is an example of custom row and column labels on a correlation matrix calculated with a single matrix:

png("corplot.png", width=5, height=5, units="in", res=200)
op <- par(mar=c(6,6,1,1), ps=10)
COR <- cor(iris[,1:4])
image(x=seq(nrow(COR)), y=seq(ncol(COR)), z=cor(iris[,1:4]), axes=F, xlab="", ylab="")
text(expand.grid(x=seq(dim(COR)[1]), y=seq(dim(COR)[2])), labels=round(c(COR),2))
box()
axis(1, at=seq(nrow(COR)), labels = rownames(COR), las=2)
axis(2, at=seq(ncol(COR)), labels = colnames(COR), las=1)
par(op)
dev.off()

In addition to the angular json filter already mentioned, there is also the angular toJson() function.

angular.toJson(obj, pretty);

The second param of this function lets you switch on pretty printing and set the number of spaces to use.

If set to true, the JSON output will contain newlines and whitespace. If set to an integer, the JSON output will contain that many spaces per indentation.

(default: 2)

you can add a condition to the after_update like so:

class SomeModel < ActiveRecord::Base
  after_update :send_notification, if: :published_changed?

  ...
end

there's no need to add a condition within the send_notification method itself.

You can write like this:

img{
    width:100%;
    max-width:600px;
}

jsonweb seems to be the best solution for me. See http://www.jsonweb.info/en/latest/

from jsonweb.encode import to_object, dumper

@to_object()
class DataModel(object):
  def __init__(self, id, value):
   self.id = id
   self.value = value

>>> data = DataModel(5, "foo")
>>> dumper(data)
'{"__type__": "DataModel", "id": 5, "value": "foo"}'

Simple answer to this; I was trying to figure out the same thing, and it just hit me.

GitHub IS a program installed on your computer, and when it runs, it WILL use threads and RAM. So that makes it a process. All you have to do is open Task Manager, click the Processes tab, find 'Github.exe', right click, Open File Location. Voila! Mine is in some App folder in Local, about 4 layers deep.

Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.

I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.

The API appears to have changed (or at least, it doesn't work for me).

Running the following in the Package Manager Console works as expected:

Update-Database -Script -SourceMigration:0

This will drop the outermost level from the hierarchical column index:

df = data.groupby(...).agg(...)
df.columns = df.columns.droplevel(0)

If you'd like to keep the outermost level, you can use the ravel() function on the multi-level column to form new labels:

df.columns = ["_".join(x) for x in df.columns.ravel()]

For example:

import pandas as pd
import pandas.rpy.common as com
import numpy as np

data = com.load_data('Loblolly')
print(data.head())
#     height  age Seed
# 1     4.51    3  301
# 15   10.89    5  301
# 29   28.72   10  301
# 43   41.74   15  301
# 57   52.70   20  301

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
print(df.head())
#       age     height           
#       sum        std       mean
# Seed                           
# 301    78  22.638417  33.246667
# 303    78  23.499706  34.106667
# 305    78  23.927090  35.115000
# 307    78  22.222266  31.328333
# 309    78  23.132574  33.781667

df.columns = df.columns.droplevel(0)
print(df.head())

yields

      sum        std       mean
Seed                           
301    78  22.638417  33.246667
303    78  23.499706  34.106667
305    78  23.927090  35.115000
307    78  22.222266  31.328333
309    78  23.132574  33.781667

Alternatively, to keep the first level of the index:

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
df.columns = ["_".join(x) for x in df.columns.ravel()]

yields

      age_sum   height_std  height_mean
Seed                           
301        78    22.638417    33.246667
303        78    23.499706    34.106667
305        78    23.927090    35.115000
307        78    22.222266    31.328333
309        78    23.132574    33.781667

You need to wrap the text in a div element and include the absolutely positioned element inside of it.

<div class="container">
    <div class="inner">
        <div class="full-height"></div>
        [Your text here]
    </div>
</div>

Css:

.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }

Setting the inner div's position to relative makes the absolutely position elements inside of it base their position and height on it rather than on the .container div, which has a fixed height. Without the inner, relatively positioned div, the .full-height div will always calculate its dimensions and position based on .container.

When I want to split the screens I usually do one of the following:

1. open new window with: Ctrl+Shift+N
   and after that I drag the current file I want to the new window.
2. on the File explorer - I hit Ctrl+Enter on the file I want - and then this file and the other file open together in the same screen but in split mode, so you can see the two files together. If the screen is wide enough this is not a bad solution at all that you can get used to.

Maybe because other languages do this as well, so it is generally-accepted behavior. (For good reasons, as shown in the other answers)

I believe that using "cbind" is the simplest way to add a column to a data frame in R. Below an example:

    myDf = data.frame(index=seq(1,10,1), Val=seq(1,10,1))
    newCol= seq(2,20,2)
    myDf = cbind(myDf,newCol)

For me I usually send back an HttpResponseException and set the status code accordingly depending on the exception thrown and if the exception is fatal or not will determine whether I send back the HttpResponseException immediately.

At the end of the day it's an API sending back responses and not views, so I think it's fine to send back a message with the exception and status code to the consumer. I currently haven't needed to accumulate errors and send them back as most exceptions are usually due to incorrect parameters or calls etc.

An example in my app is that sometimes the client will ask for data, but there isn't any data available so I throw a custom NoDataAvailableException and let it bubble to the Web API app, where then in my custom filter which captures it sending back a relevant message along with the correct status code.

I am not 100% sure on what's the best practice for this, but this is working for me currently so that's what I'm doing.

Update:

Since I answered this question a few blog posts have been written on the topic:

https://weblogs.asp.net/fredriknormen/asp-net-web-api-exception-handling

(this one has some new features in the nightly builds) https://docs.microsoft.com/archive/blogs/youssefm/error-handling-in-asp-net-webapi

Update 2

Update to our error handling process, we have two cases:

1. For general errors like not found, or invalid parameters being passed to an action we return a HttpResponseException to stop processing immediately. Additionally for model errors in our actions we will hand the model state dictionary to the Request.CreateErrorResponse extension and wrap it in a HttpResponseException. Adding the model state dictionary results in a list of the model errors sent in the response body.

2. For errors that occur in higher layers, server errors, we let the exception bubble to the Web API app, here we have a global exception filter which looks at the exception, logs it with ELMAH and tries to make sense of it setting the correct HTTP status code and a relevant friendly error message as the body again in a HttpResponseException. For exceptions that we aren't expecting the client will receive the default 500 internal server error, but a generic message due to security reasons.

Update 3

Recently, after picking up Web API 2, for sending back general errors we now use the IHttpActionResult interface, specifically the built in classes for in the System.Web.Http.Results namespace such as NotFound, BadRequest when they fit, if they don't we extend them, for example a NotFound result with a response message:

public class NotFoundWithMessageResult : IHttpActionResult
{
    private string message;

    public NotFoundWithMessageResult(string message)
    {
        this.message = message;
    }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var response = new HttpResponseMessage(HttpStatusCode.NotFound);
        response.Content = new StringContent(message);
        return Task.FromResult(response);
    }
}

For me, the below code worked well:

import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;

With the (xml file):

androidx.constraintlayout.widget.ConstraintLayout xmlns:android="...."

I just had a quick look at your example, but if i understood it the right way you're trying to add 404 routes to dynamic segments. I had the same issue a couple of days ago, found #458 and #1103 and ended up with a hand made check within the render function:

if (!place) return <NotFound />;

hope that helps!

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?

The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)

def doAppend( size=10000 ):
    result = []
    for i in range(size):
        message= "some unique object %d" % ( i, )
        result.append(message)
    return result

def doAllocate( size=10000 ):
    result=size*[None]
    for i in range(size):
        message= "some unique object %d" % ( i, )
        result[i]= message
    return result

Results. (evaluate each function 144 times and average the duration)

simple append 0.0102
pre-allocate  0.0098

Conclusion. It barely matters.

Premature optimization is the root of all evil.

In Java 9, you can now use Matcher#results() to get a Stream<MatchResult> which you can use to get a list/array of matches.

import java.util.regex.Pattern;
import java.util.regex.MatchResult;

String[] matches = Pattern.compile("your regex here")
                          .matcher("string to search from here")
                          .results()
                          .map(MatchResult::group)
                          .toArray(String[]::new);
                    // or .collect(Collectors.toList())

Java has a method for this, "convertStringArrayToIntArray".

String numbers = sc.nextLine();
int[] intArray = convertStringArrayToIntArray(numbers.split(", "));

Here you can find a complete guide for MySQL case statements in SQL.

CASE
     WHEN some_condition THEN return_some_value
     ELSE return_some_other_value
END

For deleting use http://www.php.net/manual/en/function.unlink.php Hope you'll can to write logic?

The script below allows having a single handler for all exit conditions. It uses an app specific callback function to perform custom cleanup code.

cleanup.js

// Object to capture process exits and call app specific cleanup function

function noOp() {};

exports.Cleanup = function Cleanup(callback) {

  // attach user callback to the process event emitter
  // if no callback, it will still exit gracefully on Ctrl-C
  callback = callback || noOp;
  process.on('cleanup',callback);

  // do app specific cleaning before exiting
  process.on('exit', function () {
    process.emit('cleanup');
  });

  // catch ctrl+c event and exit normally
  process.on('SIGINT', function () {
    console.log('Ctrl-C...');
    process.exit(2);
  });

  //catch uncaught exceptions, trace, then exit normally
  process.on('uncaughtException', function(e) {
    console.log('Uncaught Exception...');
    console.log(e.stack);
    process.exit(99);
  });
};

This code intercepts uncaught exceptions, Ctrl+C and normal exit events. It then calls a single optional user cleanup callback function before exiting, handling all exit conditions with a single object.

The module simply extends the process object instead of defining another event emitter. Without an app specific callback the cleanup defaults to a no op function. This was sufficient for my use where child processes were left running when exiting by Ctrl+C.

You can easily add other exit events such as SIGHUP as desired. Note: per NodeJS manual, SIGKILL cannot have a listener. The test code below demonstrates various ways of using cleanup.js

// test cleanup.js on version 0.10.21

// loads module and registers app specific cleanup callback...
var cleanup = require('./cleanup').Cleanup(myCleanup);
//var cleanup = require('./cleanup').Cleanup(); // will call noOp

// defines app specific callback...
function myCleanup() {
  console.log('App specific cleanup code...');
};

// All of the following code is only needed for test demo

// Prevents the program from closing instantly
process.stdin.resume();

// Emits an uncaught exception when called because module does not exist
function error() {
  console.log('error');
  var x = require('');
};

// Try each of the following one at a time:

// Uncomment the next line to test exiting on an uncaught exception
//setTimeout(error,2000);

// Uncomment the next line to test exiting normally
//setTimeout(function(){process.exit(3)}, 2000);

// Type Ctrl-C to test forced exit 

You just have to change to a Custom format - right click and select format and at the bottom of the list is custom.

 0.00##\%;[Red](0.00##\%)

The first part of custom format is your defined format you posted. Everything after the semicolon is for negative numbers. [RED] tells Excel to make the negative numbers red and the () make sure that negative number is in parentheses.

Make sure that your permissions are correct on the folder.As i faced same problem and after changing the ownership of the folder and files the problem was solved.

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

To list local packages with the version number use:

npm ls --depth=0

To list global packages with the version number use:

npm ls -g --depth=0

I think you need something like:

var text= data.response.venue.tips.groups[0].items[1].text;

If file really exists and you want to replace it use below code:

string file = "c:\test\SomeFile.txt"
string moveTo = "c:\test\test\SomeFile.txt"

if (File.Exists(moveTo))
{
    File.Delete(moveTo);
}

File.Move(file, moveTo);

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

http://docs.scipy.org/doc/numpy/user/basics.indexing.html#boolean-or-mask-index-arrays

You need to put the "\n" in the strings.xml file not within the page layout.

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

[A1].End(xlUp)
[A1].End(xlDown)
[A1].End(xlToLeft)
[A1].End(xlToRight)

is the VBA equivalent of being in Cell A1 and pressing Ctrl + Any arrow key. It will continue to travel in that direction until it hits the last cell of data, or if you use this command to move from a cell that is the last cell of data it will travel until it hits the next cell containing data.

If you wanted to find that last "used" cell in Column A, you could go to A65536 (for example, in an XL93-97 workbook) and press Ctrl + Up to "snap" to the last used cell. Or in VBA you would write:

Range("A65536").End(xlUp) which again can be re-written as Range("A" & Rows.Count).End(xlUp) for compatibility reasons across workbooks with different numbers of rows.

For me, the problem was that I copied something from an example and used

<item name="android:windowTranslucentStatus">true</item>

just removing this fixed my problem.

Well you can simply use Math.pow(a,b) as you have used earlier and just convert its value by using (int) before it. Below could be used as an example to it.

int x = (int) Math.pow(a,b);

where a and b could be double or int values as you want. This will simply convert its output to an integer value as you required.

After writing

header('HTTP/1.0 404 Not Found');

add one more header for any inexisting page on your site. It works, for sure.

header("Location: http://yoursite/nowhere");
die;

If you are running in a local server, such as wamp or xampp, make sure it's using the php.ini you think it is. These servers usually default to a php.ini that's not in your html docs folder.

In my case i had to load images on radio button click, I just uses the regular onclick event and it worked for me.

 <input type="radio" name="colors" value="{{color.id}}" id="{{color.id}}-option" class="color_radion"  onclick="return get_images(this, {{color.id}})">

<script>
  function get_images(obj, color){
    console.log($("input[type='radio'][name='colors']:checked").val());

  }
  </script>

Use children() and each(), you can optionally pass a selector to children

$('#mydiv').children('input').each(function () {
    alert(this.value); // "this" is the current element in the loop
});

You could also just use the immediate child selector:

$('#mydiv > input').each(function () { /* ... */ });

I hope this is one of the basic conditional classes

Solution: 1

<section [ngClass]="(condition)? 'class1 class2 ... classN' : 'another class1 ... classN' ">

Solution 2

<section [ngClass]="(condition)? 'class1 class2 ... classN' : '(condition)? 'class1 class2 ... classN':'another class' ">

Solution 3

<section [ngClass]="'myclass': condition, 'className2': condition2">

I know this question is very old, but just came up with the same problem and solved it myself, so I'm answering in case anyone finds this through google as I did. I based my solution on @Andrew's one, but basically modified everything afterwards.

EDIT: seeing how popular this has been lately, I decided to update also the styles to make it look more like 2014 and less like windows 95. I fixed the bugs @Quantico and @Trengot spotted so now it's a more solid answer.

EDIT 2: I set it up with StackSnippets as they're a really cool new feature. I leave the good jsfiddle here for reference thought (click on the 4th panel to see them work).

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

You will need to do:

$boot2docker init
$boot2docker start

The following settings fixed the issue:

$export DOCKER_HOST=tcp://192.168.59.103:2376
$export DOCKER_CERT_PATH=/Users/{profileName}/.boot2docker/certs/boot2docker-vm
$export DOCKER_TLS_VERIFY=1

Buffers can be used for taking a string or piece of data and doing base64 encoding of the result. For example:

You can install Buffer via npm like :- npm i buffer --save

you can use this in your js file like this :-

var buffer = require('buffer/').Buffer;

->> console.log(buffer.from("Hello Vishal Thakur").toString('base64'));
SGVsbG8gVmlzaGFsIFRoYWt1cg==  // Result

->> console.log(buffer.from("SGVsbG8gVmlzaGFsIFRoYWt1cg==", 'base64').toString('ascii'))
Hello Vishal Thakur   // Result

Compare outer and inner height/widths to get the total margin and padding:

var that = $("#myId");
alert(that.outerHeight(true) - that.innerHeight());

}

<div class="showhim">HOVER ME_x000D_
  <div class="showme">hai</div>_x000D_
</div>

jsfiddle

Since this answer is popular I think a small explanation is needed. Using this method when you hover on the internal element, it wont disappear. Because the .showme is inside .showhim it will not disappear when you move your mouse between the two lines of text (or whatever it is).

These are example of quirqs you need to take care of when implementing such behavior.

It all depends what you need this for. This method is better for a menu style scenario, while Yi Jiang's is better for tooltips.

I prefer this simple XML hack which makes columns clickable in SSMS on a cell-by-cell basis. With this method, you can view your data quickly in SSMS’s tabular view and click on particular cells to see the full value when they are interesting. This is identical to the OP’s technique except that it avoids the XML errors.

SELECT
     e.EventID
    ,CAST(REPLACE(REPLACE(e.Details, '&', '&amp;'), '<', '&lt;') AS XML) Details
FROM Events e
WHERE 1=1
AND e.EventID BETWEEN 13920 AND 13930
;

This should give you a list of all the tables in your database

SELECT Distinct TABLE_NAME FROM information_schema.TABLES

So you can use it similar to your database check.

If NOT EXISTS(SELECT Distinct TABLE_NAME FROM information_schema.TABLES Where TABLE_NAME = 'Your_Table')
BEGIN
    --CREATE TABLE Your_Table
END
GO

If you have a std::wstring object, you can call c_str() on it to get a wchar_t*:

std::wstring name( L"Steve Nash" );
const wchar_t* szName = name.c_str();

Since you are operating on a narrow string, however, you would first need to widen it. There are various options here; one is to use Windows' built-in MultiByteToWideChar routine. That will give you an LPWSTR, which is equivalent to wchar_t*.

Use this code in sub Fragment of MainActivity to call the method on it.

((MainActivity) getActivity()).startChronometer();

Designated initializes will be supported in c++2a, but you don't have to wait, because they are officialy supported by GCC, Clang and MSVC.

    const char* world;
};

int main () 
{
    hello_world hw = {
        .hello = "hello, ",
        .world = "world!"
    };
    
    std::cout << hw.hello << hw.world << std::endl;
    return 0;
}

There is a major error in the tutorials destined for newbies here: http://developer.android.com/training/basics/actionbar/styling.html

It is major because it is almost impossible to detect cause of error for a newbie.

The error is that this tutorial explicitly states that the tutorial is valid for api level 11 (Android 3.0), while in reality this is only true for the theme Theme.Holo (without further extensions and variants)

But this tutorial uses the the theme Theme.holo.Light.DarkActionBar which is only a valid theme from api level 14 (Android 4.0) and above.

This is only one of many examples on errors found in these tutorials (which are great in other regards). Somebody should correct these errors this weekend because they are really costly and annoying timethieves. If there is a way I can send this info to the Android team, then please tell me and I will do it. Hopefully, however, they read Stackoverflow. (let me suggest: The Android team should consider to put someone newbie to try out all tutorials as a qualification that they are valid).

Another error I (and countless other people) have found is that the appcombat backward compliance module really is not working if you strictly follow the tutorials. Error unknown. I had to give up.

Regarding the error in this thread, here is a quote from the tutorial text with italics on the mismatch:

" For Android 3.0 and higher only

When supporting Android 3.0 and higher only, you can define the action bar's background like this:

    <resources>
        <!-- the theme applied to the application or activity -->
        <style name="CustomActionBarTheme"
        parent="@style/Theme.Holo.Light.DarkActionBar"> 

ERROR1: Only Theme.Holo can be used with Android 3.0. Therefore, remove the "Light.DarkActionBar etc.

ERROR2: @style/Theme.Holo"> will not work. It is necessary to write @android:style/Theme.Holo">in order to indicate that it is a built in Theme that is being referenced. (A bit strange that "built in" is not the default, but needs to be stated?)

The compiler advice for error correction is to define api level 14 as minimum sdk. This is not optimal because it creates incompliance to Andreoid 3.0 (api level 11). Therefore, I use Theme.Holo only and this seems to work fine (a fresh finding, though).

I am using Netbeans with Android support. Works nicely.

The ConnectTimeout option allows you to tell your ssh client how long you're willing to wait for a connection before returning an error. By setting ConnectTimeout to 1, you're effectively saying "try for at most 1 second and then fail if you haven't connected yet".

The problem is that when you connect by name, the DNS lookup can take several seconds. Connecting by IP address is much faster, and may actually work in one second or less. What sinelaw is experiencing is that every attempt to connect by DNS name is failing to occur within one second. The default setting of ConnectTimeout defers to the linux kernel connect timeout, which is usually pretty long.

To follow up on Rachel's answer.
Here's two ways in which you can get Mouse Screen Coordinates in WPF.

1.Using Windows Forms. Add a reference to System.Windows.Forms

public static Point GetMousePositionWindowsForms()
{
    var point = Control.MousePosition;
    return new Point(point.X, point.Y);
}

2.Using Win32

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool GetCursorPos(ref Win32Point pt);

[StructLayout(LayoutKind.Sequential)]
internal struct Win32Point
{
    public Int32 X;
    public Int32 Y;
};
public static Point GetMousePosition()
{
    var w32Mouse = new Win32Point();
    GetCursorPos(ref w32Mouse);

    return new Point(w32Mouse.X, w32Mouse.Y);
}

If the code in your question doesn't work, you probably have not implemented equals(Object) on the Customer class appropriately.

Presumably there is some key (let us call it customerId) that uniquely identifies a customer; e.g.

class Customer {
    private String customerId;
    ...

An appropriate definition of equals(Object) would look like this:

    public boolean equals(Object obj) {
        if (obj == this) {
            return true;
        }
        if (!(obj instanceof Customer)) {
            return false;
        }
        Customer other = (Customer) obj;
        return this.customerId.equals(other.customerId);
    }

For completeness, you should also implement hashCode so that two Customer objects that are equal will return the same hash value. A matching hashCode for the above definition of equals would be:

    public int hashCode() {
        return customerId.hashCode();
    }

It is also worth noting that this is not an efficient way to remove duplicates if the list is large. (For a list with N customers, you will need to perform N*(N-1)/2 comparisons in the worst case; i.e. when there are no duplicates.) For a more efficient solution you should use something like a HashSet to do the duplicate checking.

I'm resurrecting the dead here, but because a range can be defined as "A:A", using a for each loop ends up with a potential infinite loop. The solution, as far as I know, is to use the Do Until loop.

Do Until Selection.Value = ""
  Rem Do things here...
Loop

I think you'd be interested in the H1 debate. It's a debate about whether to use the h1 element for the page's title or for the logo.

Personally I'd go with your first suggestion, something along these lines:

<div id="header">
    <a href="http://example.com/"><img src="images/logo.png" id="site-logo" alt="MyCorp" /></a>
</div>

<!-- or alternatively (with css in a stylesheet ofc-->
<div id="header">
    <div id="logo" style="background: url('logo.png'); display: block; 
        float: left; width: 100px; height: 50px;">
        <a href="#" style="display: block; height: 50px; width: 100px;">
            <span style="visibility: hidden;">Homepage</span>
        </a>
    </div>
    <!-- with css in a stylesheet: -->
    <div id="logo"><a href="#"><span>Homepage</span></a></div>
</div>


<div id="body">
    <h1>About Us</h1>
    <p>MyCorp has been dealing in narcotics for over nine-thousand years...</p>
</div>

Of course this depends on whether your design uses page titles but this is my stance on this issue.

JSONArray objects have a function getJSONObject(int index), you can loop through all of the JSONObjects by writing a simple for-loop:

JSONArray array;
for(int n = 0; n < array.length(); n++)
{
    JSONObject object = array.getJSONObject(n);
    // do some stuff....
}

$(OBJDIR):
    mkdir $@

Which also works for multiple directories, e.g..

OBJDIRS := $(sort $(dir $(OBJECTS)))

$(OBJDIRS):
    mkdir $@

Adding $(OBJDIR) as the first target works well.

I came up with some kind of solution to the problem. It involves jquery and css. This works like toggle but instead of toggling the display of elements it just changes its properties upon alternate clicks. Upon clicking the div it rotates the element with tag 180 degrees and when you click it again the element with tag returns to its original position. If you want to change the animation duration just change transition-duration property.

CSS

#example1{
transition-duration:1s;
}

jQuery

$(document).ready( function ()  {  var toggle = 1;
  $('div').click( function () {
      toggle++;
      if ( (toggle%2)==0){
          $('#example1').css( {'transform': 'rotate(180deg)'});
      }
      else{
          $('#example1').css({'transform': 'rotate(0deg)'});
      }
  });

});

My version is I think a little more understandable because my C# knowledge is not so high. I'm using this algorithm: http://easyguyevo.hubpages.com/hub/Convert-Hex-to-Decimal (The Example 2)

Late reading this, but.. The way I read your question, you only need to change two lines of code:

Accept user input, function writes back on screen.

<input type="text" id="userInput"=> give me input</input>
<button onclick="test()">Submit</button>

<!-- add this line for function to write into -->
<p id="demo"></p>   

<script type="text/javascript">
function test(){
    var userInput = document.getElementById("userInput").value;
    document.getElementById("demo").innerHTML = userInput;
}
</script>

You can as long as

• The value is unique
• No existing foreign keys are violated

oninput event is very useful to track input fields changes.

However it is not supported in IE version < 9. But older IE versions has its own proprietary event onpropertychange that does the same as oninput.

So you can use it this way:

$(':input').on('input propertychange');

To have a full crossbrowser support.

Since the propertychange can be triggered for ANY property change, for example, the disabled property is changed, then you want to do include this:

$(':input').on('propertychange input', function (e) {
    var valueChanged = false;

    if (e.type=='propertychange') {
        valueChanged = e.originalEvent.propertyName=='value';
    } else {
        valueChanged = true;
    }
    if (valueChanged) {
        /* Code goes here */
    }
});

I don't think you properly understood what you read. If it gets compiled to the correct type, then there is no difference. When I do this:

var i = 42;

The compiler knows it's an int, and generate code as if I had written

int i = 42;

As the post you linked to says, it gets compiled to the same type. It's not a runtime check or anything else requiring extra code. The compiler just figures out what the type must be, and uses that.

In case it helps somebody else, I got this error message after accidentally deleting .git/objects/

fatal: Not a git repository (or any of the parent directories): .git

Restoring it solved the problem.

TypeScript 0.9+ has a specification for enums:

enum AnimationType {
    BOUNCE,
    DROP,
}

The final comma is optional.

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

Try this explanation on...

TypeSafe means that variables are statically checked for appropriate assignment at compile time. For example, consder a string or an integer. These two different data types cannot be cross-assigned (ie, you can't assign an integer to a string nor can you assign a string to an integer).

For non-typesafe behavior, consider this:

object x = 89;
int y;

if you attempt to do this:

y = x;

the compiler throws an error that says it can't convert a System.Object to an Integer. You need to do that explicitly. One way would be:

y = Convert.ToInt32( x );

The assignment above is not typesafe. A typesafe assignement is where the types can directly be assigned to each other.

Non typesafe collections abound in ASP.NET (eg, the application, session, and viewstate collections). The good news about these collections is that (minimizing multiple server state management considerations) you can put pretty much any data type in any of the three collections. The bad news: because these collections aren't typesafe, you'll need to cast the values appropriately when you fetch them back out.

For example:

Session[ "x" ] = 34;

works fine. But to assign the integer value back, you'll need to:

int i = Convert.ToInt32( Session[ "x" ] );

Read about generics for ways that facility helps you easily implement typesafe collections.

C# is a typesafe language but watch for articles about C# 4.0; interesting dynamic possibilities loom (is it a good thing that C# is essentially getting Option Strict: Off... we'll see).

use zzz instead of TZD

Example:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

On a native Windows install, you can either use batch(cmd.exe) or vbscript without the need to get external tools. Here's an example in vbscript:

Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
Set objFile = objFS.OpenTextFile(strFile)
Do Until objFile.AtEndOfStream
    strLine = objFile.ReadLine
    If InStr(strLine,"ex3")> 0 Then
        strLine = Replace(strLine,"ex3","ex5")
    End If 
    WScript.Echo strLine
Loop    

Save as myreplace.vbs and on the command line:

c:\test> cscript /nologo myreplace.vbs  > newfile
c:\test> ren newfile file.txt

For Mojave users, I found this page very useful, particularly this suggestion:

/usr/bin/wish $(which gitk)

...without that, the window did not display correctly!

If you're on Windows, you may find the config file my.ini it in this directory

C:\ProgramData\MySQL\MySQL Server 5.7\

You open this file in a text editor and look for this section:

# The TCP/IP Port the MySQL Server will listen on
port=3306

Then you change the number of the port, save the file. Find the service MYSQL57 under Task Manager > Services and restart it.

Lazy Loading? Well, it simply means that child records are not fetched immediately, but automatically as soon as you try to access them.

Use a boolean:

let prevent_touch = true;
document.documentElement.addEventListener('touchmove', touchMove, false);
function touchMove(event) { 
    if (prevent_touch) event.preventDefault(); 
}

I use this in a Progressive Web App to prevent scrolling/zooming on some 'pages' while allowing on others.

import json

if json.dumps(dict1) == json.dumps(dict2):
    print("Equal")

if you do this: sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6. You may get this error:

E: Unable to locate package lib32bz2-1.0

E: Couldn't find any package by glob 'lib32bz2-1.0'

E: Couldn't find any package by regex 'lib32bz2-1.0'

So i suggest just doing this:

sudo apt-get install lib32stdc++6

And also, the AOSP should look for how while installing Android-Studio, that is installed too.

Please post your Model Class.

To check the errors in your ModelState use the following code:

var errors = ModelState
    .Where(x => x.Value.Errors.Count > 0)
    .Select(x => new { x.Key, x.Value.Errors })
    .ToArray();

OR: You can also use

var errors = ModelState.Values.SelectMany(v => v.Errors);

Place a break point at the above line and see what are the errors in your ModelState.

The problem was solved by reinstalling Visual Studio 2015.

The following example is from the Code Project article, (Almost) Everything In Active Directory via C#:

// userDn is a Distinguished Name such as:
// "LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com"
public ArrayList Groups(string userDn, bool recursive)
{
    ArrayList groupMemberships = new ArrayList();
    return AttributeValuesMultiString("memberOf", userDn,
        groupMemberships, recursive);
}

public ArrayList AttributeValuesMultiString(string attributeName,
     string objectDn, ArrayList valuesCollection, bool recursive)
{
    DirectoryEntry ent = new DirectoryEntry(objectDn);
    PropertyValueCollection ValueCollection = ent.Properties[attributeName];
    IEnumerator en = ValueCollection.GetEnumerator();

    while (en.MoveNext())
    {
        if (en.Current != null)
        {
            if (!valuesCollection.Contains(en.Current.ToString()))
            {
                valuesCollection.Add(en.Current.ToString());
                if (recursive)
                {
                    AttributeValuesMultiString(attributeName, "LDAP://" +
                    en.Current.ToString(), valuesCollection, true);
                }
            }
        }
    }
    ent.Close();
    ent.Dispose();
    return valuesCollection;
}

Just call the Groups method with the Distinguished Name for the user, and pass in the bool flag to indicate if you want to include nested / child groups memberships in your resulting ArrayList:

ArrayList groups = Groups("LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com", true);
foreach (string groupName in groups)
{
    Console.WriteLine(groupName);
}

If you need to do any serious level of Active Directory programming in .NET I highly recommend bookmarking & reviewing the Code Project article I mentioned above.

If we are use chosen dropdown list, then we can use below css(No JS/JQuery require)

<select chosen="{width: '100%'}" ng- 
   model="modelName" class="form-control input- 
   sm"
   ng- 
   options="persons.persons as 
   persons.persons for persons in 
   jsonData"
   ng- 
   change="anyFunction(anyParam)" 
   required>
   <option value=""> </option>
</select>
<style>   
.chosen-container .chosen-drop {
    border-bottom: 0;
    border-top: 1px solid #aaa;
    top: auto;
    bottom: 40px;
}

.chosen-container.chosen-with-drop .chosen-single {
    border-top-left-radius: 0px;
    border-top-right-radius: 0px;

    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;

    background-image: none;
}

.chosen-container.chosen-with-drop .chosen-drop {
    border-bottom-left-radius: 0px;
    border-bottom-right-radius: 0px;

    border-top-left-radius: 5px;
    border-top-right-radius: 5px;

    box-shadow: none;

    margin-bottom: -16px;
}
</style>

Although the answers are 100% correct, a small suggestion to improve null case handling of the list itself with Optional:

 List<String> listOfStuffFiltered = Optional.ofNullable(listOfStuff)
                .orElseGet(Collections::emptyList)
                .stream()
                .filter(Objects::nonNull)
                .collect(Collectors.toList());

The part Optional.ofNullable(listOfStuff).orElseGet(Collections::emptyList) will allow you to handle nicely the case when listOfStuff is null and return an emptyList instead of failing with NullPointerException.

You also get this error when expecting something in the beforeAll function!

describe('...', function () {

    beforeAll(function () {
        ...

        expect(element(by.css('[id="title"]')).isDisplayed()).toBe(true);
    });

    it('should successfully ...', function () {

    }
}

u can call event function like (focusout) or (blur) then u put your code

<div tabindex=0 (blur)="outsideClick()">raw data </div>
 

 outsideClick() {
  alert('put your condition here');
   }
