If you want a similar solution but are more comfortable in python then also check out hyde: http://ringce.com/hyde

It's very similar in spirit but uses python and the corresponding tools to get the job done.

Another Python blog engine: https://github.com/ametaireau/pelican

I'm using it for a new-baby-picture-proud-parents blog (which I won't link to due to its private nature). It's not very feature-rich, but it gets the job done.

For Node.js there is DocPad: https://github.com/balupton/docpad
