Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)

Deploying Rails app using Docker and Capistrano

Concept

Remote server:

• Docker container with Passenger

• Data volume (directory on the remote host) to store files for the app

• Directory structure in data volume (directory /data/apps/app1):

This template is supposed to be applied to rails 5.

run with:

rails new <application_name> --template=https://gist.githubusercontent.com/karloku/edd6a158e275fdefa334/raw/b56175bee5b45d32310aeb620e23be44e3c2a56d/graphql_template.rb -T

using gems:

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

See question on stack overflow: http://stackoverflow.com/questions/28595636/rails-4-how-to-give-alias-names-to-includes-and-joins-in-active-record-que

- Model Student and model Teacher are both STI models with super class model User
- Model Story is a STI model with super class model Task
- includes() and joins(), both fails

Rails alias naming convention (includes() and joins())

- One model as parameter
  - is base model (includes(:users))
