I read somewhere before that you should only ever optimise code during development if it produces a ten fold performance gain and that during maintainance optimisation should be done if it provides a two-fold increase in performance.

It’s likely that I read it in some eXtreme Programming book as this is the kind of gross generalisations that XP practitioners make (thought they generally have a large grain of truth). However, I can’t find or remember the reference to the paraphrased quote. If anyone on planet MiNDS> or in the general blogsphere could remember the source I’d be greatful.

Laptop sleep and hibernate work under Ubuntu out-of -the-box on my Dell C640. Also there’s this nice little update app that negates the need to type “apt-get update && apt-get upgrade”. It’s a nice little GUI that works.

I’ve also been using Muine instead of Rhythmbox to play my Ogg Vorbis collection. It’s a really nice app with a very simple but clean and effective UI.

It also looks like the Ubuntu people are picking up the NetworkManager technology that I like in Fedora. I’ve also had two patches acceted into the Gnome 2.10 release of Metacity. They’re trivial patches, but it’s a start. I intend to do more Metacity hacking in the future, the codebase is remarkably clean and easy to understand.

I think I’ll be sticking with Ubuntu for a while. I really like Fedora but the availability of Mono, Evince and proper laptop suspend support on Ubuntu are killer features for me.
