Upscale 1080p to 4k using ffmpeg

Just use the command below:

ffmpeg -i INPUT_FILE \
  -vf scale=3840x2160:flags=lanczos \
  -c:v libx264 \
  -crf 13 \
 -c:a aac -b:a 512k \

If .DS_Store was never added to your git repository, simply add it to your .gitignore file.

If you don't have one, create a file called

.gitignore

In your the root directory of your app and simply write

Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
bundle
Run RAILS_ENV=production rake db:create db:migrate db:seed
Run rake secret and copy the output
From the command line: export SECRET_KEY_BASE=output-of-rake-secret
To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.

In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So ⌘ + D does not mean hold shift. ⌘ + Shift + D does of course.

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`

	require 'openssl'

	def encrypt_string(str)
	cipher_salt1 = 'some-random-salt-'
	cipher_salt2 = 'another-random-salt-'
	cipher = OpenSSL::Cipher.new('AES-128-ECB').encrypt
	cipher.key = OpenSSL::PKCS5.pbkdf2_hmac_sha1(cipher_salt1, cipher_salt2, 20_000, cipher.key_len)
	encrypted = cipher.update(str) + cipher.final
	encrypted.unpack('H*')[0].upcase
	end
