Well, that is of course total bullshit. With that title I will conduct a small experiment.
I found that the least informative of my blog posts attract the most readers. So if this stays true with that post (and a title like that should attract at least some attention) I will add more noise here. Promise!
It is not chrismas, hence no quiz, but this was strangely surprising:
class A
@@t = "A::@@t"
T="A::T"
def self.s1; @@t; end
def self.s2; T; end
end
class B < A
def self.s1; @@t; end
def self.s2; T; end
end
class C < A
@@t = "C::@@t"
T="C::T"
def self.s1; @@t; [...]
class Array
def to_proc
proc do |obj|
self.map { |sym| obj.send(sym) }
end
end
end
gives you
Account.all.map(&%w(id email))

While some of my 5 readers on average (per day) might already know, for everyone else: CouchDB will be part of the next Ubuntu release. And that one comes with long time support.
Congratulations, Couchies.
