When life hands you lemons...

If you're unemployed, and want to know how many days it's been, how many years experience you have, and with which companies, this Ruby class will tell you. Basically, initialize the WorkHistoryAnalysis class, pass in each experience as "<name>, [start date], [end date]" in YYYY,MM,DD format as shown at the bottom of the file. A little report will be generated at the console.

	require 'date';
	class WorkHistoryAnalysis
	attr_accessor :total, :company, :latest
	def initialize()
	@total_days = 0
	@company = Hash.new
	@latest = Date.new
	end
	def workedFor(who, from, to)
	to_d = Date.new(to[0],to[1],to[2])
	from_d = Date.new(from[0],from[1],from[2])
	latest?(to_d)
	days = (to_d - from_d).to_i
	if (@company.has_key?(who))
	@company[who] += days
	else
	@company[who] = days
	end
	@total_days += days
	end
	def latest?(dat)
	if ((dat <=> @latest) > 0)
	@latest = dat
	else
	return false
	end
	return true
	end
	def employed
	years = days2yrs(@total_days)
	return ["Employed for:"],[" #{years} years [#{@total_days} total days]"]
	end
	def unemployed
	days = (Date.today - @latest).to_i
	years = days2yrs(days)
	return ["Currently unemployed for:"],[" #{years} years [#{days} days]"],["Last worked:"],[" #{@latest.to_s}"]
	end
	def days2yrs(days)
	years = days/365.to_f
	return (years * 100).round.to_f / 100
	end
	def list_experiences
	str = "Employment breakdown by company:\n"
	co = @company.sort_by { |k,v| v }
	co.each { |a| str += " #{a[0]} #{days2yrs(a[1])} years [#{a[1]} days]\n" }
	return str
	end
	def print
	puts employed
	puts unemployed
	puts list_experiences
	end
	end
	W = WorkHistoryAnalysis.new
	W.workedFor("NWlink",[1996,2,1],[1997,7,1])
	W.workedFor("Orrtax",[1997,8,1],[2000,1,1])
	W.workedFor("Hostpro",[2000,2,1],[2001,11,1])
	W.workedFor("College",[2002,4,1],[2005,12,16])
	W.workedFor("Microsoft",[2006,1,1],[2006,5,1])
	W.workedFor("Marchex",[2006,6,1],[2008,4,1])
	W.workedFor("Microsoft",[2008,10,1],[2009,9,26])
	W.print
