While we are on the subject of funny-looking yellow busses, how about this Topsy-Turvy bus? Created by car artist Tom Kennedy, the bus toured the US last year to “dramatically depict America’s upside down budget priorities”. Link

14-year-old Sam Hawthorne was bitten by a shark in his sleep! He was sleepwalking one night and walked right into a trophy shark’s head that was hanging on his bedroom wall. His mother found him bleeding from a wound on the cheek, and the shark still imbedded in his face.

'The shark must have been embedded in Sam's cheek for about 15 minutes and he was in a lot of pain,' she said.

Fortunately, Sam escaped with just a small scar. 'It was the most frightening experience of my life,' he said.

Working from home is not easy, but it’s easier when you have an office you can use just for work. If you have a shed or room to build one, it can become a home office away from the distractions of the house. Here are twenty such shed offices that have been customized to the max. I’ll take the Manhattan rooftop shed! Pictured is a greenhouse that was converted to an office. Link

Toyota and subsidiary Hino Motors are joining forces with Japan Rail Hokkaido to develop vehicles that can drive on roads and railways. The DMV (Dual Mode Vehicle) has rubber tires and steel wheels, and can convert in about 15 seconds. They began testing the vehicles 18 months ago.

Combing the versatility of a bus with the speed of a train has allowed Japan Rail to tailor routes and services to the communities it serves. Rather than scuttling service on under-utilized lines, Japan Rail has simply switched to smaller vehicles.

Dual-mode vehicles would be a great addition to America's mass transit infrastructure. It would make rail transit feasible in those areas that don't have the population density to support a lot of stations, and make mass transit a more viable option for exurbs. Riders could simply hop on at a bus stop in their neighborhood, then ride the rails to their destination.

The new vehicles also use a lot less diesel fuel than conventional busses. http://blog.wired.com/cars/2008/05/half-bus-half-t.html

On May 27th, 1937, the new Golden Gate Bridge in San Francisco officially opened to pedestrian traffic. Vehicles weren’t allowed until the next day. Wired has a look at the bridge’s construction timeline stretching back to 1869, and some statistics.

The Golden Gate Bridge was an engineering marvel. The site alone -- buffeted by high winds and split by the swirling currents of the Golden Gate -- made construction treacherous. The sheer size of the bridge (the longest suspension bridge in the world until the Verrazano-Narrows Bridge opened in 1964) required several innovations in bridge-building technology, especially where it came to constructing the two colossal anchorages in -- and under -- turbulent water.

Of all the mind-boggling statistics surrounding the bridge's construction, and there are plenty, perhaps the most jaw-dropping involves the two main suspension cables. Each measures 7,659 feet in length and each used hundreds of pencil-thick wires bound together to make a cable just over three feet in diameter. In all, more than 80,000 miles of steel wire was needed, enough to circle the earth three times.

If you’re having a Memorial Day picnic today, you probably won’t see this in time, but the summer is long. Instructables has directions for cutting your watermelon in a way that makes it easy to remove most of the seeds. I think it may take a bit of practice, but that just means more watermelon!

Atractaspis are also called mole vipers, burrowing asps, burrowing adders, stiletto snakes, or side-stabbing snakes. They can bite without opening their mouths!

Burrowing asps have a highly reduced dentition, with just two particularly elongate maxillary fangs (up to a third of total skull length), two short, gently curved dentary teeth, and a couple of very small palatine teeth[...}. The maxillary fangs (there are two in each maxilla, one of which is a replacement tooth kept in reserve) are huge compared to the short, block-like maxilla: in fact virtually its entire length is occupied by the transversely arranged fang sockets. The maxilla articulates with the relatively immobile prefrontal by way of a saddle-shaped joint (this contrasts with the condition in viperids, where the articulatory surfaces between the maxilla and prefrontal are flat), allowing the maxilla to easily rotate posterodorsally and anteroventrally.

Rotating teeth? I didn’t need to hear that! These snakes burrow underground and live in Africa and the Middle East. Link

The New York Times posted a profile of the webcomic xkcd and its creator, Randall Munroe. They titled it “This Is Funny Only if You Know Unix”. I beg to differ, since I don’t know Unix and I find his comics hilarious almost all the time.

Mr. Munroe has become something of a cult hero. He counts himself as among the fewer than two dozen creators of comic strips on the Web who make a living at it.

At Google headquarters, a required stop on the geek-cult-hero speaking tour, he recently addressed hundreds of engineers, some of whom dutifully waited for him to sign their laptops. He said he had only wanted a tour of the place but had instead been invited to speak. The real thrill, he said, was that a hero of his, Donald Knuth, a professor emeritus of computer science at Stanford and a programming pioneer, was in the front row.

“It’s comparable to Bill Gates’s being in the front row,” he said. “I got to have lunch with him. He’s in his 70s, but people he is in touch with must have told him about it.”
