The Selfish Programmer

Using Ruby at work is great… but sometimes it feels like a job!

This year, I rediscovered the joy of writing Ruby apps for nobody but myself—and you should, too! Solo development is a great way to learn skills, to find inspiration, and to distill what matters most about programming.

Building an entire app by yourself can be overwhelming, but this talk will make it easier. We'll start with a minimal toolset that one person can maintain. You'll learn how many "bad" coding practices can actually reduce complexity. You may be surprised how selfish coding can make you a better team member, too!

Details

I'd like to share some git aliases that you might find useful if you handle pull requests from others.

Add these to your ~/.gitconfig in the [alias] section:

copr = "!f() { git fetch -fu origin refs/pull/$1/head:pr-$1; git checkout pr-$1; } ; f"
prunepr = "!git for-each-ref refs/heads/pr-* --format='%(refname:short)' | while read ref ; do git branch -D $ref ; done"

Now you can "git copr #{pr_number}" (check out pull request is the mnemonic) and it will pull down the PR in a local branch of pr-#{pr_number} and check it out for you. To do it right, you must pronounce it "Copper" with a James Cagney gangster accent.

Venue Considerations Checklist

Facility
- Security/Maintenence
  - Will venue provide staff person(s) day of event for coordination?
  - Who is contact point in case of problems
- Room(s)
  - Number of individual meeting spaces
  - Capacity of each
  - Relative arrangement of rooms (are they close to each other)
Outdoor/shared space to facilitate hallway track

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.


	require 'set'
	require 'find'

	class Array
	def to_h; Hash[self]; end
	def to_set; Set.new(self); end
	def freq; group_by {\|e\| e }.map {\|k,v\| [k,v.count] }.to_h; end
	end

	[alias]
	review = log -p --reverse -M -C -C --patience
	review-topic = !sh -c 'git review ${1}^1..${1}^2' -
	view-topic = !sh -c 'git log --reverse --stat -M -C -C ${1}^1..${1}^2' -

	Interview Day
	- Set and communicate a schedule (“two-three hours, no laptop needed, we will get lunch, no need to dress up”)
	- Set expectations (“we will be writing some code together”)
	- Have a diverse set of interviewers
	- Allow for breaks

	Make a game plan
	- assign areas of focus (you do SQL, I’ll do OO)

	Deploying a Rails 3 App with EC2 + S3 + Ubuntu + Capistrano + Passenger
	=======================================================================

	EC2 Setup
	---------
	1 Launch New ec2 instance - ami-1634de7f
	2 Create elastic IP [ELASTIC_IP] and associate it with instance
	3 go to domain registrar DNS settings, @ and www to ELASTIC_IP
	4 set the `:host` in `config/deploy.rb` to ELASTIC_IP
