Operable Software

What does it mean to make software that doesn't just run, but is operable?

Good question! This represents some current thinking on the topic; there's tons of details in each of these things, so this list is expected to change and get more detailed over time.

Operable Software seems to involve (at a minimum) thinking a lot harder about and making sure there is a strategy (and code where appropriate) for:

Metrics
Logging

	require 'open-uri'
	require 'uri'
	require 'rss/1.0'

	seconds = (Time.now - self).to_i

	hash = Hash.new{\|h,k\| h[k] = [0,0]}
	aggregate_n = (ARGV[0] \|\| 1).to_i

	STDIN.each_line do \|line\|
	parts = line.split(",")
	key = parts[2][1..-2]
	prefix = key.split(":")[0..(-1-aggregate_n)].join(":")
	size = parts[3]
