Zoran Perkov is one of the heroes portrayed in Flash Boys. Someone liked my review of the book, which made me re-read the review and setup a Google alert on him. This video was one of the first hits on a search for him. His thing is:
Failure is feature of complex systems.
Basically when you build a complex system, you risk failure. Complexity allows us to more easily adapt to customer need. Complexity also increases the risk of novel failure. Things we did not even know could go wrong (unknown unknowns) probably will. The trick is, responding to them.
Basically, we should have mechanisms in place which act to reduce the effect of performance spikes. The more options we have to deal with these events, the better we will be able to handle them. The smaller the toolkit, the less capable we are to respond.
The delivery is not that great, but the ideas behind it is something I’ve agreed with for a long time.
I first encountered the Fibonacci number series around 10 or 11 taking a class at the university offered to kids to make them excited about learning. In addition to math, I took rocket building, speed reading, and others. About this time I hated school, but I really enjoyed these because those teaching it always approached the material like Arthur Benjamin in this video: Look at this amazing thing!
Deep Blue versus Kasparov was an pivotal moment for me. At the time I was playing lots of chess on the computer. (And usually losing.) So the prospect the best player in the world cannot beat a computer was a depressing prospect. Maybe it is a sign of how much I had matured (or immatured) to think a computer could beat someone better than me at trivia. Maybe it has something to do with routinely using computers to compile things for me in minutes that would take me days.
Kudos to Lindsey for recommending this. I had watched it before he said something, but I was surprised that I had not posted it on this blog because…
I’m not this obsessive when I get interested in something. Like Adam though, I never feel I know have or done enough.
MythBusters co-host Adam Savage gives a fast-paced presentation on personal obsessions. Savage explains how his fascination with dodo bird skeletons eventually led to his designing of an exact bronze-cast replica of the titular statue from the 1941 Humphrey Bogart movie, “The Maltese Falcon.”
Fifty years ago today, John Glenn was the first American to orbit the Earth. For some reason, Alan Shepard, Jr. being the first American in space did not impress me as a kid. Going up and coming back down did not count. Achieving orbit was realer space. Glenn was the American response to Yuri Gagarin being the first human to orbit the Earth on 12 April 1961.
Stephen Hawking missed his 70th birthday party this past weekend. He was not feeling well. There has been quite a bit floating around the Internet about how he as survived decades after getting an estimated months to live. Even Intel talked up how they are working on a way to help him speak faster.
Speaking late Sunday on the sidelines of a conference celebrating Hawking’s 70th birthday in the English city of Cambridge, Intel Chief Technology Officer Justin Rattner said his company had a team in England to explore ways to help the celebrity scientist communicate more quickly.
Given research into thought powered devices, I would really like to see a cyborg Stephen Hawking controlling things digitally. There are some cool bio feedback techniques to control cursors and pick out items from a screen. From what I understand, picking out the word he wants with where he looks from choices is getting slower from missing. Bypassing the eyes which used to be fast and going straight to the brain through electrodes could be very cool.
The problem is… Electrodes are invasive, often heal very slowly, and get infections. Too bad helmets which read our brain waves a la Macross proved much less effective. (Accuracy is paramount and anything sitting on a head is likely to miss.)
I was sequestered in a war room for a month during which the Japanese earthquake and tsunami happened as well as the meltdown of the nuclear power plant at Fukushima. We projected on the wall video of the stories over and over.
It just occurred to me each of the Empedocles classical elements (air, fire, earth, and water) have threatened a nuclear power plant this year. True, only the one event resulted in a melt down. Still, it is interesting how a bit of everything has been a problem.
Fire: “A raging wildfire in Los Alamos on Monday briefly entered the property of the nation’s preeminent nuclear facility, Los Alamos National Laboratory, a vast complex that houses research laboratories and a plutonium facility.”
Water: “The head of the Nuclear Regulatory Commission has been dispatched to a nuclear power plant in Fort Calhoun, Neb., where a berm collapsed Sunday…. The breach allowed Missouri River flood waters to reach containment buildings and transformers and forcing the shutdown of electrical power.”
Before you ask, no, the classical elements are not fighting back against the modern elements (Uranium and Plutonium).
“U.S. nuclear facilities remain safe,” Mr. Jaczko told two House Energy and Commerce subcommittees, which had originally planned to consider his agency’s budget for the coming fiscal year at the hearing. “We will continue to work to maintain that level of protection.” Reactors are designed to meet the challenges of “the most severe natural phenomena historically reported,” he said. For earthquakes, that means any that occur within 200 miles of the reactor, and a margin of error, he said.
Jaczko sounds similar to the planning the Japanese did. Earlier I read a Wired Science article, Japan Quake Epicenter Was in Unexpected Location, which said the Japanese looked to patterns in the past to determine the future. Therefore they expected a strong earthquake in the south where the Phillipine plate is overdue for a massive event.
Japan has been expecting and preparing for the “big one” for more than 30 years. But the magnitude-9.0 temblor that struck March 11 — the world’s fourth biggest quake since 1900 — wasn’t the catastrophe the island nation had in mind. The epicenter of the quake was about 80 miles east of the city of Sendai, in a strip of ocean crust previously thought unlikely to be capable of unleashing such energy. “This area has a long history of earthquakes, but [the Sendai earthquake] doesn’t fit the pattern,” says Harold Tobin, a marine geophysicist at the University of Wisconsin-Madison. “The expectation was high for a 7.5, but that’s a hundred times smaller than a 9.0.”
It sounds to me like, if in the United States the most powerful earthquake in the area of a nuclear reactor was a 7.5 magnitude event, then a 9.0 could surprise those running it. Given a 9.0 is a hundred times more powerful and a broken reactor so dangerous, I would hope the preparedness is for the larger even where seemingly unlikely.
The Haiti quake was “expected“. However the Chilean, both New Zealand, and the Sendai earthquakes have all sounded unexpected. Of course, living on the Ring of Fire, how can any earthquake be unexpected?
These people can help you out! How to Build a Container City I ran across this briefly while flipping channels. Very interesting. I mean, people live in trailers which are really fairly similar. However, I am guess these are very upscale and hundreds of pounds per unit.
