Interesting Things

You can never return: ... except when you can. From a block, that is. Returning from a block rarely works:

result = ['one', 'two'].each do |x|
 return x
end
=> LocalJumpError: unexpected return

But, you can pass next and break arguments, which will allow you to assign return values from the block:

result = ['one', 'two'].each do |x|
  break(x)
end
=> "one"


result = ['one', 'two'].each do |x|
  next(x)
end
=> ["one", "two"]

You can return from a lambda, though.

Check out Google Page Speed, which is like Yahoo's YSlow, only "better."

Page Speed is an open-source Firefox/Firebug Add-on. Webmasters and web developers can use Page Speed to evaluate the performance of their web pages and to get suggestions on how to improve them.
Like chef? Love capistrano? Check out chef-deploy, which "... Uses the same directory layout as capistrano and steals the git remote cached deploy strategy from cap and adapts it to work without cap and under chef."
SFTUG FTW! Another successful SF Tracker User Group Meetup on 06/24. Watch for future events on the Meetup site.
