openssl 1.0 + ruby-1.9.1-p378 patch (for Fedora 12)

Okay, so if you're using Fedora 12 and trying to install 1.9.1, you may be having some problems.

This is because Fedora 12 is using an openssl 1.0 beta, which requires a few changes in Ruby. (all versions)

Unfortunately the patches I've seen were for 1.8.6, as this is such a new issue.

If you're using rvm you can use openssl-0.9.8k like this:

rvm install openssl
rvm install 1.9.1 -C --with-openssl-dir=$HOME/.rvm/usr

P0W! Done.

Otherwise, you can get my updated patch at http://gist.github.com/299682
This patch is not guaranteed to work. It worked for me but YMMV and if it eats your cat don't blame me.

Rails 3 environment settings using Passenger + Apache

I had some trouble getting Passenger to run my rails 3 app in development mode today, it wanted to use production even with RailsEnv development. Turns out that while it was ignoring that, it was respecting RackEnv development. Yay! I didn't investigate further, I'm happy using RackEnv.

Basic generic products db

Here is a basic design for a generic product database using STI. This allows different kinds of things to be gropuped by class and inherited normally, and makes it easy to have different associations/association rules on similiar things. Something like a cart, is an order by another name, and just has to be re-typed into something like CompletedOrder when completed.

A handy hash method

I am testing posting code :)

def except(*arr)
hsh = self.dup
arr.each do |k|
hsh.delete(k)
end
