Github Questions

Q1:

Knowing what you know about GitHub, how would you design the high level infrastructure for github.com? What sequence of steps would happen when loading http://www.github.com in a browser? Don't worry about describing the specific libraries and services that handle each step.

A1:

Assumptions

Well, let's start with a few assumptions so we're on the same page:

marksim

require 'rspec'

def next_server_number(server_numbers)
  server_numbers.sort.each.with_index do |s, i|
    return i+1 if s > i+1
  end
  return server_numbers.count + 1
end

describe 'next_server_number' do

#!/usr/bin/ruby
version = ARGV.first

if version
  releases = `heroku releases -n 50 --remote=production | grep Deploy | grep -A1 #{ARGV.first}`
  commits = releases.split("\n").reverse.map {|r| r.split(/\s/)[3] }.join('..')
  command = 'git log --pretty=format:"%h - %an, %ar : %s" ' + commits
  puts `#{command}`
else
  puts "A version is required:  ex: release_notes v191"
