17. MY NEEDS
• Minimally Invasive
• do not unpack to a temporary location
• small as can be
• Wide deployment capabilities
• more than linux, mac, windows, cygwin
18. Statically Compile
embedded Ruby
C + ruby extensions
+ main wrapper
+ standard library
Ruby + application code
Crate based application
Pack into Amalgalite
20. Inexact Size Measurements
Executable + C
Ruby libs
extensions
Ruby 1.8.6 2.4 M 8.4 M
Crate/ruby 1.8.6 2.9 M 1.9 M

12 if load_error.message =~ /#{Regexp.escape filename}z/ then

25. ISSUE #1 - AUTOLOAD
• Problem
• bypasses the require chain setup by amalgalite
• used by rack, active_support, active_record
• Solution
• Port tree style patches?
• custom gem builds?
26. ISSUE #2 - VIEWS IN WEB
FRAMEWORKS
• Problem
• layout and templates loaded from disk
• Solution
• wait for Rails 3
• sinatra, others, make patches for upstream, if needed.
27. ISSUE #3 - CLASS RELOADING
• Problem
• Development mode reloads classes
• Solution ( for now )
• production mode when running as crate based apps
