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...

public function facebook() { return $this->socialite->driver('facebook')->stateless()->redirect()->getTargetUrl(); } This will return the URL that the consumer of the API must provide to the end user to get authorization from Facebook.

EXPOSE <port> [<port>...] From Docker's documentation: The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. EXPOSE does not make the ports of the container accessible to the host. To do that, you must use either the -p flag to ...

The notation 'thing is equal to (quote thing). The reader will do the expansion: > (read-from-string "'a") (QUOTE A) Quoting is used to prevent further evaluation. The quoted object evaluates to itself. > 'a A > (eval '+ 1 2) 3

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...

// Using Visual Format Language requires a special look-up dictionary of names<->views. var views = new NSDictionary( nameof(someLabel), someLabel, nameof(anotherLabel), anotherLabel, nameof(oneMoreLabel), oneMoreLabel ); // It can also take a look-up dictionary for metrics (...

It is possible to mount a host directory to a specific path in your container using the -v or --volume command line option. The following example will mount /etc on the host to /mnt/etc in the container: (on linux) docker run -v "/etc:/mnt/etc" alpine cat /mnt/etc/passwd (on windows) do...

By default, containers created with docker run are given a random hostname. You can give the container a different hostname by passing the --hostname flag: docker run --hostname redbox -d ubuntu:14.04

git diff myfile.txt Shows the changes between the previous commit of the specified file (myfile.txt) and the locally-modified version that has not yet been staged. This also works for directories: git diff documentation The above shows the changes between the previous commit of all files in ...

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...

To temporarily mark a file as ignored (pass file as parameter to alias) - type: unwatch = update-index --assume-unchanged To start tracking file again - type: watch = update-index --no-assume-unchanged To list all files that has been temporarily ignored - type: unwatched = "!git ls-fil...

To get all the information for a container you can run: docker inspect <container>

You can get an specific information from a container by running: docker inspect -f '<format>' <container> For instance, you can get the Network Settings by running: docker inspect -f '{{ .NetworkSettings }}' <container> You can also get just the IP address: docker inspect ...

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...

Compiling C programs requires you to work with five kinds of files: Source files: These files contain function definitions, and have names which end in .c by convention. Note: .cc and .cpp are C++ files; not C files. e.g., foo.c Header files: These files contain function prototypes and va...

Sometimes it's necessary to convert a Discriminated Union to and from a string: module UnionConversion open Microsoft.FSharp.Reflection let toString (x: 'a) = match FSharpValue.GetUnionFields(x, typeof<'a>) with | case, _ -> case.Name let fromStri...
