First, you'll need to incorporate the extension:

class ApplicationRecord < ActiveRecord::Base

Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.

How to capture, stitch and publish a 360° timelapse

Consumer ready 360° cameras are becoming ever more accessible and many people are experimenting with a variety of 360° content. Out of the many cameras on the market the Ricoh Theta S is one of the most user-friendly, turn-key solutions with lots of built-in features. However, the camera's videos are limited 1920x960 resolution and the Theta+ app only lets you create a timelapse with up to 300 or 400 images. The workaround is to use interval shooting to capture as many images as you'd like at the 5376x2688 to full resolution and then stitch them together manually into an HD video. There are few GUI solutions (especially open-source/free) which let you do this with ease. Here's how you do it:

Set up interval shooting on your Ricoh Theta S

FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

  • ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file
