Richie Jackson: Psychedelic Skater
I believe in psychedelicism. Not just psychedelic music, but everything. A psychedelic experience is characterized as the unveiling of perceptions previously unknown -- the brain unfettered from its usual constraints. To me, it's all there is, and certainly all that's worth doing. I find no worth in that which doesn't surprise. Anomalies, irregularities, deviation from the common rule -- that is all I will ever care for.

Leopard Vs. Crocodile
Leopard Vs. Crocodile
The Clash of the Titans
I shot this sequence of photos in Kruger National Park, South Africa.
It is the only time this behavior has ever been photographed. Ever.
People have witnessed crocodiles killing leopards but rarely the other way around.
This crocodile is probably about 7 feet long and therefore not even half of full size. (Nile crocodiles grow to roughly 15 feet). But still it is pretty evenly size-matched with this leopard.
For the full story about the day this happened, and what it was like to experience this once-in-history event, read my photo story The Best Day Ever.

Bletchley Park kicks so much butt
Bletchley Park kicks so much butt
Yesterday, I got one of the best and most memorable birthday presents of my life -- a trip to the legendary Bletchley Park, site of the British WWII codebreaking effort, where Turing and co invented modern computer science and cryptography. The site is just as I'd imagined it -- a rotting, lovely old mansion surrounded by modest, slope-shouldered sheds with a variety of exhibits staffed by knowledgeable, friendly geeks who clearly find it all every bit as exciting as I do.
The exhibits are a nice mix of technical and historical, ranging from a truly impressive collection of memorabilia related to Winston Churchill (who visited Bletchley and congratulated the women and men there on their excellent work), including his school report-card that makes him out to be a villainous, disruptive and scattered child; to a series of exhibits of vintage wartime toys. There's a museum of ancient cinematographic equipment complete with a beautiful little theatre that shows reels of vintage newsreels and propaganda films. And of course, there are the computers and related devices.
The cipher machines and radio equipment naturally form the centerpiece of the museum, and there's an entire computer history museum onsite (it was closed, with the strangest sign I've ever seen, words to the effect of, "This site is closed for maintenance. Enter at your own risk. You may be escorted off the grounds by security if you are caught here." Huh?) along with the notorious Nazi Enigma machine that was kidnapped in 2000 and ransomed back (the crime was never solved). The historic material on the Enigma (which began life as a commercial product before the war!) is really excellent, as are the technical explanations of how it worked.
But best of all are the "rebuilds" -- reconstructions from plans of the bombes (parallel decoding machines) and Colossus (the massive and gorgeous machine that was one of the earliest general-purpose computers. These hulking beasts are real artisanal pieces, with the hand-crafted, prideful look of devices built by loving and obsessive engineers who really, really care about their work.
Walking the grounds, I got a real sense of the lives of the people who'd worked at Bletchley, through a series of exhibitions that included quotations from oral histories about the dress, romance, food, family life and internecine conflict that characterized Bletchley Park during the war years. The exhibit on clothing was especially memorable, if only because it could bring home the gold for Britain in the 2012 Scariest Mannequin event, as was the astoundingly cool room devoted to the wartime use of messenger pigeons, including replicas of the awards given to especially brave and dedicated birds.
We spent three hours on site and barely scratched the surface. We had hardly any time to look at the war-plane, didn't get to the gigantic model railroad exhibit, didn't see the whole film presentation at the Enigma theatre, and only got the most hurried of walks around the American Gardens -- and we missed the mansion tour altogether. I could have easily spent eight or more hours there, and still wanted for more. Just the tantalizing mini-lecture I got on the Colossus rebuild from one of the electronics engineers who worked on it was enough to pique my interest, and I could have spent an hour looking at the details in Turing's office.
The Trust that runs Bletchley Park has done a really fine job, and is clearly thinking creatively about the best way to continue to fund their operations. The mansion's slate roof is in need of a multi-million-pound replacement, and they're selling "genuine fragments" of the existing slate -- holy relics of crypto's formative years, as well as soliciting donations and selling memberships. But most intriguing was the idea of renting out part or all of the site for parties and weddings -- maybe for my 40th birthday in three years...

The instructions supplied explain how Pocket Enigma works and take the user step-by-step through the process of coding and decoding. Worked examples and carefully annotated figures illustrate how the Key and Message Setting are used, and there is a trouble-shooting table to help with common errors. For young readers there is also a simplified way of using it called Junior Pocket Enigma making it suitable for all ages who can read and write their own messages.
Computer mouse heading for extinction
Are the Wii MotionPlus and iPhone examples of how we'll be using PCs in years to come? Experts say the humble input device is being usurped by touch screens and facial recognition.
Gartner said that innovations from electronics firms creating new interactive interfaces for gaming and smartphones are driving the demise of the mouse.
Steven Prentice, vice president and Gartner Fellow, told the BBC that devices such as Nintendo's MotionPlus for the Wii and Apple's iPhone point the way to the future, offering greater accuracy in motion detection.
"With the Wii you point and shake and it vibrates back at you so you have a two-way relationship," said the analyst.
"The new generation of smartphones like the iPhone all now have tilting mechanisms or you can shake the device to do one or more things."
Prentice also highlighted home entertainment efforts from Panasonic which employ hand and facial recognition techniques to display information in place of a conventional remote control.
However, while the mouse's 40 year-old reign is coming to an end, the keyboard is here to stay, according to the analyst.
"For all its faults, the keyboard will remain the primary text input device. Nothing is easily going to replace it," he said. "But the idea of a keyboard with a mouse as a control interface is breaking down."

Heart surgery for 100-year-olds
Heart surgery for 100-year-olds
Not all doctors approve of increasingly common aggressive treatments for 'late-elderly' patients
July 20, 2008Anemona Hartocollis
NEW YORK TIMES
When Hazel Homer was 99, more than one doctor advised that there was little to be done about her failing heart except wait for it to fail a final time. But Homer was not interested in waiting to die.
Now, at 104, her heart is still ticking, thanks to a specialized pacemaker and defibrillator that synchronizes her heartbeat and can administer a slight shock to revive her if her heart falters.
Her operation, a month shy of her 100th birthday, reflects what some doctors are hailing as a new frontier in medicine: successful surgery for centenarians. But others say such aggressive treatment for what are euphemistically known as the "late elderly" can be wasteful and barbaric, warning that the rush to test the limits of technology can give patients false hope and compound their health challenges with surgical complications.
"She's just a peek into the future," said Dr. Steven Greenberg, a Long Island, N.Y., cardiologist who performed Homer's surgery, for which the average Medicare reimbursement at the time was $35,000.
It's hard to track, since people over 75 are scarcely represented in clinical trials, but several geriatricians said procedures that two decades ago were seldom considered for people in their 90s are now increasingly commonplace. They include hip and knee replacement, cataract surgery, heart valve replacement, bypass operations, pacemaker implantation and treatment for slow-growing cancers that afflict areas like the prostate.
The Census Bureau says there were 90,422 centenarians in America in June, up from 50,454 in 2000. Demographers project there could be 1.1 million by 2050.
With such rapid growth of centenarians, debate has mounted over how far to go in providing major medical services to extend already very long lives.
Dr. David Goodman, a co-author of the Dartmouth Atlas of Health Care, said there is much research suggesting most aggressive treatment of late-stage chronic diseases doesn't actually prolong life and can actually decrease its quality.
Of Homer, Goodman said: "The odds are that she's really an amazing exception. The question is not a relatively healthy, smart, sensible 99-year-old getting a life-prolonging procedure, one that prolongs the quality of life. The question becomes the 82-year-old with dementia who has cancer or congestive heart failure."
Greenberg, a cardiologist at St. Francis Hospital in Roslyn, N.Y., said Homer is his oldest patient, and one of a handful of people nationwide her age who have received this type of heart device. But he has implanted about two dozen devices like hers in patients 90 or older over the past five years and he counts among his patients a 93-year-old "with a full head of hair" who got a defibrillator in his 80s and is still practising law.
Then there's Dr. Michael DeBakey, the pioneering heart surgeon who died July 11 at age 99. Two years ago, DeBakey underwent an aortic-dissection repair procedure that he himself had long before devised – but only after doctors convened an ethics committee to decide whether it was appropriate.
Homer did not receive a regular pacemaker but rather a biventricular defibrillator, which synchronizes her heartbeat and can automatically shock her to save her from a fatal arrhythmia. In 2007, about 55,000 people received such combination devices according to Greenberg, a consultant to the three main manufacturers of the device, who estimated that people 90 or older accounted for fewer than 100 of the devices.
Dr. Karen Alexander, an associate professor of cardiology at Duke University, said the defibrillator might go too far. "Many people say that would be a nice way to go when you're 100: to be sleeping and have your heart stop. The defibrillator component would very possibly prevent that."
Greenberg admits he "wouldn't have wanted to advertise" the operation on Homer when it was unclear how long she would survive. Now, he argues that the operation cost less than repeated hospitalizations for heart failure.
"People pay more for their BMW, which will not save their life," he said.Lawn Chair Balloonist Makes It to Idaho
