Remove moving objects such as tourists or passing cars from your photos. Take multiple photos from the same scene and the «Tourist Remover» blends them into a composite photo without any interfering elements.
A free service from snampmania.com. I’ve not tried this yet as I don’t have a suitable set to use, but if it works, and I can download the resultant composite image again at decent resolution, I think I’ll be using this a lot.

The Unevenness of Space-Time Convergence « Strange Maps:
How long does it take to travel from London to elsewhere? The answer is provided by this map, showing a set of expanding circles centered on the British capital, each bigger one delineating two extra hours of travel time.
The familiar shape of the world is morphed into grotesque, contorted shapes as these isotemporal lines replace the usual lines of longitude and latitude for frame of reference.
This is from 1981, so it’s not quite as accurate any more. I’d love to see it redrawn.

British Standards Institute introduces Standard British Idiots:
Following a 30 percent increase in domestic accidents, the British Standards Institute has recruited 1000 Standard British Idiots (SBIs) to perform safety tests on a range of appliances. A spokesperson explained: ‘For years we have worked on the assumption that nobody in their right mind would stick a spoon into a live socket, but they do. We have recruited this calibre of person: someone who will look for a gas leak with a match, or set off across the channel on a lilo.’
I’m thinking of setting up a nomination web page for them.
The Evolution of House Cats: Scientific American:
[genetic analysis] revealed five genetic clusters, or lineages, of wildcats. Four of these lineages corresponded neatly with four of the known subspecies of wildcat and dwelled in specific places: F. silvestris silvestris in Europe, F. s. bieti in China, F. s. ornata in Central Asia and F. s. cafra in southern Africa. The fifth lineage, however, included not only the fifth known subspecies of wildcat — F. s. lybica in the Middle East—but also the hundreds of domestic cats that were sampled, including purebred and mixed-breed felines from the U.S., the U.K. and Japan. In fact, genetically, F. s. lybica wildcats collected in remote deserts of Israel, the United Arab Emirates and Saudi Arabia were virtually indistinguishable from domestic cats. That the domestic cats grouped with F. s. lybica alone among wildcats meant that domestic cats arose in a single locale, the Middle East, and not in other places where wildcats are common.
The article goes on to postulate that wildcats took advantage of increased rodent populations in proximity to humans, caused by the commencement of agriculture approximately 10,000 years ago in the Middle East’s Fertile Crescent — much earlier and in a different location to the established wisdom of where the relationship between man and cat started. Makes sense though.

Nothing to see here. Just testing.
I’m glad to see that finally, some scientific investigation is being done on this old canard. And it turns out you don’t need to drink litres of water per day at all:
According to Heinz Valtin, a retired professor of physiology from Dartmouth Medical School who specialized in kidney research and spent 45 years studying the biological system that keeps the water in our bodies in balance, the answer is no.
The National Academy of Sciences’s Institute of Medicine also researched this in 2004:
Its panel on “dietary preference intakes for electrolytes and water” noted that women who appear adequately hydrated consume about 91 ounces (2.7 liters) of water a day and men about 125 ounces (3.7 liters). These seemingly large quantities come from a variety of sources—including coffee, tea, milk, soda, juice, fruits, vegetables and other foods. Instead of recommending how much extra water a person should drink to maintain health, the panel simply concluded that “the vast majority of healthy people adequately meet their daily hydration needs by letting thirst be their guide.”
So there you go. Your body has a perfectly good way of telling you it needs a bit of topping up. Short of an illness that requires you to over-hydrate, or weather requiring the same, drink when you’re thirsty and stop worrying.
