Hacking Club Mate "imatate"

Read about the end result here

Join me when I start brewing my first batch of Club Mate. Inspired by a podcast from chaos radio express on the topic "Hackerbrausen" (Hacker's soda, listen here) I want to try this by myself.

So far I have bought all the necessary ingrediends and tools to get started. And with the help from Jan (@janl) I can even carbonate the end result :)

When? Where?

# Include an anonymous module

# Useful for defining a class with a base module. So, instead of:
#
#   class Foo
#     module Base
#       def bar
#         # ...
#       end
#     end

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
