4chan’s guide to converting GIF to WebM - https://boards.4chan.org/g/res/41212767
View webm.md

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
  • -crf values can go from 4 to 63. Lower values mean better quality.
  • -b:v is the maximum allowed bitrate. Higher means better quality.

Lambda: standard

# Creating a lambda
l = lambda { |name| "Hi #{name}!" }

# Executing the lambda
l.call("foo") # => Hi foo!

Notes From "Practical Object-Oriented Design In Ruby" by Sandi Metz
View poodir-notes.md

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

  • Single Responsibility Principle: a class should have only a single responsibility
  • Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
  • Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
  • Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

Self

In Ruby, self is a special variable that always references the current object.

  • Inside class or module definition, self refer to the Class or Module object.
  • Inside instance method, self refer to future instance object.
  • Inside class method, self refer to the class.i

Rails 4 Standard CRUD Controller

# No flash messages are set with this controller.

You can’t perform that action at this time.
