Today started out stunning - sun, no wind, not a cloud in the sky - but as normal this state of affairs declined to persist and faded away into a mediocre cloudy afternoon. I hence decided to spend my Saturday afternoon pursuing that rather superb collection of museums out in South Kensington (V & A, Natural History and, my choice of the day, the Science Museum).

Unfortunately everyone with children within the M25 had decided on the same course of action. The tube station was chaos, the stairs packed with prams and the tickets barriers stuffed with tourists deciding at the very last moment to hand out tickets to everyone. And the museums superb exhibits were unfortunately punctuated by a horde or children (or more likely one or two very loud individuals). At one point a parent could be heard encouraging one to shout for their missing sibling. Honestly, if they must leave the interactive galleries is it so hard to at least stop their children playing hide and seek among the models of maritime steam engines?

But nevertheless the museum is excellent. And not only excellent, but free. And it's not the only one, which is one of the better highlights of living in London.

Coming home I was struck with the optimisation bug. And hence my tube map will now only draw the stations currently in the view. However, the lines draw for the entire map. Why? Because otherwise it gets rather hard to follow a line when scrolling the map.

The one vexation of the Google Maps API is that they require a key for access, which they issue for a particular hostname. This means I need different keys for development and deployment and I keep forgetting to swap them before uploading. Sigh. The terrible tribulations of life. On the other hand, if that's the worst thing then I don't have much to complain about.
