Installation

Go to the official website and choose your OS.

MacOS

Docker for Mac has a problem is the disk IO performance (see docker/for-mac#77).

There is a fix (https://github.com/IFSight/d4m-nfs) which makes Docker use NFS instead of OSXFS.

os6sense

add to gemfile :

gem 'memory_profiler', require: true, github: 'SamSaffron/memory_profiler'

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:

• graphql
• graphql-mutable_type

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?
