Re: Immutability in Ruby Part 2: Domain Models

Just ran across this. Thanks for the post.

You mentioned dkubb's ice_nine for deep freezing values, but he's also got Adamantium for creating classes whose instances are immutable. Check it out!:

Exactly. Even worse, the extra work that OO creates obscures what the code is actually doing.

"Private means you can not call a method with an explicit object
reference. This ensures that private methods can only be called within
the class that defined them."

Or from subclasses:

class Human

private
def eat
puts "yum... twinkies"
end
end

class Male < Human
def eat_meal
5.times { eat }
end
end

# outputs "yum... twinkies" five times
Male.new.eat_meal

"On step one you don’t want to cloud your head with excessive concerns about elegance, speed, or security"

This is by far the hardest part for me. I can't keep future concerns from slowing down the development of my first version, even if I've just decided to make it a "proof." Got any pearls of wisdom on how keep your mind on just-making-it-work?

Re: Database Versioning

I like this idea, but I'm wondering something: are there problems with migrating a schema just by looking at the diffs between two schema files? I would think that the DataMapper's column definitions in the model would have obviated schema migrations altogether if it was possible to reliably migrate a schema just by looking at the difference between the current schema and the desired one...

Re: Heroku | Why Instant Deployment Matters

Another variable that should be taken into account: time learning how best to deploy. Someone could be the god of web programming and still have to spend a lot of time fumbling around with Apache configs and linux file permissions.

I totally agree. Obviously the time it takes and the ease with which it can be done go hand-in-hand. Nevertheless, it is not having to think about deployment that's important to me more than deployment taking less time.

That's great news. I had a suspicion that there was a rewrite in the works since you guys have been a little quiet. I can't wait to try out the new version.
