    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.

Steps for Hosting a Website on GitHub

1. Create a GitHub account on github.com.
2. Download either [GitHub for Mac][1] or [GitHub for Windows][2], depending on your operating system. Open the app and log in using the account you just created.
3. (On Mac): After you login, click advanced and make sure that your name and email are correct. Then, click "Install Command Line Tools", just in case you want to start using the command line later in life.
4. Create a new repository in your GitHub application. Name it your-username.github.io. The name is very important. Note the folder that GitHub is saving the repository to. Make sure the "Push to GitHub?" box is checked.
5. Move your website's files into the folder that GitHub just created when you made the repository. IMPORTANT: Your homepage HTML file must be called "index.html", and it must exist in the top-level

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault
