1. Fascinating story from Reuters about the rise of high-speed stock trading, where success is measured in nanoseconds and profit is accumulated one-tenth of a penny at a time.
Lotus Capital Management LP of New York earlier this year realized that a competitor was beating it to a trade it had programed by exactly 3 microseconds, day after day. The loss meant Lotus was forfeiting about $1,000 in daily revenue on that particular trading strategy.
Lotus, a quantitative trading firm that uses high-frequency strategies, invested and tinkered, eventually shaving five microseconds from the router and two microseconds from the execution server.
This is quite long and detailed for Reuters, which typically caps features at 800-1,000 words.
2. I’ve been checking the Top 100 best-selling video-game items on Amazon. This morning, the top game was New Super Mario Bros. for Wii, while the top console was the Wii, occupying the No. 2 slot. The PlayStation 3 appeared at No. 19 (120 GB model) and No. 72 (250 GB model). The Xbox 360 was not on the list. The list featured 30 Wii games, 15 PS3 games and 12 Xbox 360 games.
3. More on space travel from from Charles Stross and why the word “starship” is misleading.
Such an interstellar capability isn’t going to look much like a “ship”. It’s going to look more like a DVD balanced on a microwave beam, or a can of beans hanging below a light sail energized by lasers powered by huge orbiting solar power stations. There won’t be any biological agencies aboard: just AGIs (artificial general intellgences) or something equivalent ported out of a fleshbody’s cranium. No hands, only nanotech assemblers. And after a voyage of decades or centuries it’s going to have to stop — somehow braking at the other end — then spend more decades farming rocks, slush and sunlight to build ever-bigger physical structures until it can build the equipment with which to phone home.
If anything, it’s going to resemble a seed pod for a different kind of life, and on arrival it’s going to hatch and grow into a tree, or a forest, or a manufacturing-industrial complex. Finally, long after arrival, it might have sufficient resources to divert from homeostasis and growth to construct a biosphere, open communications with home, and prepare to download digitized colonists — if the whole uploading concept doesn’t prove to be chimerical, and if there’s something to be done with the serialized primate core-dumps at the other end.
4. Here’s the scene from “The Matrix” where Neo dodges bullets on the rooftop. Only this one’s been done in Lego.
5. On an open thread on Kotaku, commenter Danarcho voices concerns about the tight collaboration between the military and the video-game industry. I take a more sanguine view.
