I have totally lacked the combination of energy, free time and the right mood to get going with my new code project until the last few days, but now I've finally gotten that round tuit I've been missing.
First step is to make a ruby parser for Polar HRM and PWD/PDD files, then graphing the data with scruffy in SVG and see what I can do with that and jQuery. Then, as the last step, roll it into some form of Rails training blog or something. Or perhaps just a static site generated with webby. I'll be a lot wiser when that time comes, so it makes no sense deciding anything now.
It's great just spending some hours happily hacking away at some code again. I've missed it.
