Making the most of the Google Maps API – Keeping the user on the map
Now that we have our map added to the webpage, centered on our desired location, and it takes the entire screen real estate we may want to customize it. Let us say that the application revolves around a particular city. We may want to show where the user is located in that city. For this purpose, we will just add a marker representing the user on the map. We will get the user’s location using HTML5’s Geolocation API and we will refresh his/her location on regular intervals so that his/her location stays updated. When refreshing, we may want to remove the old marker because the user may already be in a different location and we do not want thousands of markers appearing as the user moves around the map.

Creating your first middleware in Laravel 5
Middlewares can help us execute different application logic in numerous routes so that we do not repeat ourselves.They are good for filtering HTTP requests. For example, you can create a middleware which redirects user that are not authorized to view a page to another page or you can create a middleware which disallows guests from accessing pages (in fact, Laravel has such a middleware built-in). You can create a middleware which sets some HTTP headers. For example, you can enable CORS so that AJAX requests can be made from everywhere to some particular routes.
