It's the wettest July in ages. You might think that that is good weather for hacking, but no. I did discover that my raincoat is less waterproof than it ought to be. That shorted out my n900 in my pocket. It gives the kind of bing-bing sound of a low battery, then some high-pitched beeps and switches off. After shaking the water out and leaving it to dry overnight, things are fine again. Good engineering! On the other hand, if the phone had perished, I would have been looking hard at the N9.

My GPS logger, allegedly waterproof and floatable, also got waterlogged and did not fare nearly so well. I think the case developed a tiny crack when the kids dropped it and enough rain fell on it to flood it. It no longer charges.

Without my logger - I bought it some years ago after Robert Scott's talk on Open Street Map in Glasgow, Curly-Wurlies were involved, but I never got around to actually contributing to OSM, which already has good material on Nijmegen - I am now looking for something on my phone to do the same. Marble? I see it updating regularly, but I find I haven't used it for much, ever. Any other tips for a track-logging, export to useful formats (KML or UMEA sentences), doesn't-eat-batteries GPS app for the n900? Comments welcome.
