Description

Heroku is a simple way to publish your Rails app, and a powerful platform that will allow it to scale. In this episode, Jay McGavren gets you started with your first Heroku app.

Set up your Rails app

Isolate your gem environment

• You WANT Rails to fail locally if a gem isn't in your Gemfile

// Create a factory object that can be used to swap out the prototype used

    Greybeard
     
    An aging [unix hacker] type with an impressive [unix beard] that has now turned grey. Originally a young [neckbeard], these [Gandalf] resembling [curmudgeons] are renowned for their knowledge of theoretical computer science, arcane unix and complete inability to use a remotely contemporary computer.
     
    Typically employed in academia, they are a dying breed from an antediluvian age of 8" [floppies], magnetic tape and timeshared computing. Despite having invented multiuser OSes and the internet, Greybeards prefer to live in the past, where they consider [Fortran] to be a high level programming language. Typical Greybeard computers are dated [Sun workstations] or old PCs running a command line only [BSD] variant, Greybeards shun GUIs, unless they're horrible and dated, like CDE or [Amiga] Workbench.
     
    Some, like Edsger Dijkstra do most of their computer science as entirely theoretical exercises on paper and haven't programmed a computer since 1972.

(That's my attempt to understand what problem Impulse solves and how. I am not a designer/developer of this scheme.)

Problem

Regular Bitcoin transactions are not guaranteed until mined sufficiently deep in the blockchain. Unconfirmed transactions can be observed nearly instantly, but they cannot be trusted (could drop out because of insufficient fees, or double-spent).

Interface Versioning (InterVer)

Never break backcompat, keep the API nimble

An extension of SemVer with a stricter (yet more realistic) backcompat guarantee, that provides more flexibility to change the API, for libraries that are packaged and downloaded (not services accessed remotely over the Internet (see Note 4)).
