return Socialite::driver('facebook')->redirect(); This will redirect an incoming request to the appropriate URL to be authenticated. A basic example would be in a controller <?php namespace App\Http\Controllers\Auth; use Socialite; class AuthenticationController extends Controller...

/** * LoginController constructor. * @param Socialite $socialite */ public function __construct(Socialite $socialite) { $this->socialite = $socialite; } Within the constructor of your Controller, you're now able to inject the Socialite class that will help you handle login with so...

Creating a Trait trait Speak { fn speak(&self) -> String; } Implementing a Trait struct Person; struct Dog; impl Speak for Person { fn speak(&self) -> String { String::from("Hello.") } } impl Speak for Dog { fn speak(&self) ->...

Avoid destructive operations on quoted objects. Quoted objects are literal objects. They are possibly embedded in the code in some way. How this works and the effects of modifications are unspecified in the Common Lisp standard, but it can have unwanted consequences like modifying shared data, tryin...

function getContentTypes(site_url,name_of_the_library){ var ctx = new SP.ClientContext(site_url); var web = ctx.get_web(); list = web.get_lists().getByTitle(name_of_the_library); // You can include any property of the SP.ContentType object (sp.js), for this example we are just ...

$ docker run -e "ENV_VAR=foo" ubuntu /bin/bash Both -e and --env can be used to define environment variables inside of a container. It is possible to supply many environment variables using a text file: $ docker run --env-file ./env.list ubuntu /bin/bash Example environment variable...

First, remove autopublish. autopublish automatically publishes the entire database to the client-side, and so the effects of publications and subscriptions cannot be seen. To remove autopublish: $ meteor remove autopublish Then you can create publications. Below is a full example. import { Mon...

A global publication does not possess a name and does not require a subscription from the connected client and therefore it is available to the connected client as soon as the client connects to the server. To achieve this, one simply names the publication as null like so Meteor.publish(null, func...

A named publication is one that possesses a name and needs to be explicitly subscribed to from the client. Consider this server side code: Meteor.publish('somePublication', function() { return SomeCollection.find() }) The client needs to request it by: Meteor.subscribe('somePublication') ...

Meteor's default templating system Spacebars and its underlying rendering subsystem Blaze integrate seemlessly with publication lifecycle methods such that a simple piece of template code can subscribe to its own data, stop and clean up its own traces during the template tear down. In order to tap ...

Adding properties If you'd like to add properties to an existing object, you can use the Add-Member cmdlet. With PSObjects, values are kept in a type of "Note Properties" $object = New-Object -TypeName PSObject -Property @{ Name = $env:username ID = 12 Address...

Suppose you have a Dockerfile ending with ENTRYPOINT [ "nethogs"] CMD ["wlan0"] if you build this image with a docker built -t inspector . launch the image built with such a Dockerfile with a command such as docker run -it --net=host --rm inspector ,nethogs will monitor the...

If someone else wrote the code you are committing, you can give them credit with the --author option: git commit -m "msg" --author "John Smith <[email protected]>" You can also provide a pattern, which Git will use to search for previous authors: git commit -m &quo...

Users of homebrew can install gradle by running brew install gradle

Sometimes you need rewrite history with a rebase, but git push complains about doing so because you rewrote history. This can be solved with a git push --force, but consider git push --force-with-lease, indicating that you want the push to fail if the local remote-tracking branch differs from the b...

Use the rel="alternate" attribute to allow discoverability of your Atom/RSS feeds. <link rel="alternate" type="application/atom+xml" href="http://example.com/feed.xml" /> <link rel="alternate" type="application/rss+xml" href=&quo...

Date and LocalDate objects cannot be exactly converted between each other since a Date object represents both a specific day and time, while a LocalDate object does not contain time or timezone information. However, it can be useful to convert between the two if you only care about the actual date i...

Big-O notation is a notation used to talk about the long-term growth rates of functions. It's often used in the analysis of algorithms to talk about the runtime of an algorithm or related concepts like space complexity. In common usage, big-O notation is used to talk about how an algorithm's runtim...

Floating point numbers of type real cannot have any real value. They can represent real numbers up to certain amount of decimal digits. FORTRAN 77 guaranteed two floating point types and more recent standards guarantee at least two real types. Real variables may be declared as real x double prec...
