I don’t know how I got any performance tuning done before callgrind.

Actually, I do know: I used -pg with gprof.

SVG in Ruby vs. C++

(paraphrasing)

Ruby:

    def resolve_property(p)
      return send(p) if respond_to?(p)
      return parent.resolve_property(p) unless parent.nil?
      return class_for_property(p).new
    end

C++:

    /* 400 lines of resolve_property_ref<SvgProperty>::whatever 
       omitted.  */`

I promised myself I’d never write another line of autotools noise after an m4 explosion in the code mines a few years back.

My first thought was to see how usable Rake was in a non-Rails context. Turns out, it’s awesome for building C++ even outside of the pretty example rules in the docs.

I’ve noticed that, after a three year break in Ruby-land, my first big C++ project since uses a hell of a lot more dynamic_casts, and I’ve found a use a few real uses for typeid().
