On OS X the Packed Pixels display won't automatically show up as "Retina" or "HiDPI" resolution, instead the OS will use the full resolution of the display making everything tiny. This can be changed using the 3rd party app (non-free) SwitchResX.

First, download SwitchResX.

You can play with the resolutions for the Packed Pixels which is probably listed as Color LCD (2). However not all of the HiDPI resolutions work due to an OS X bug. If you are happy with any of the ones that do work then stop here, else continue.

If you're on El Capitan or later you need to disable System Integrity Protection (temporarily) to add a custom resolution for Packed Pixels. Follow the instructions from SwitchResX creator.

Now add a Custom Resolution that is "scaled". It must be 2 pixels bigger or smaller than the native resolution in one direction (this is the OS X quirk). I found bigger makes it slightly blurry so go w

Example Blog App with Auth

Pure Rails compared to Hyperloop

The purpose here is to show a high level overview of how Rails concepts map to Hyperloop concepts. It's not a full tutorial (I started doing that but it was way too long), but examples of key points.

Auth

Here's a simple auth example, with a comment showing all you have to add to hook it up to Hyperloop. In a production app you'd probably use Devise, but the Hyperloop acting_user bit would be the same!
