カークサミュエルソン.com?

Internet addresses set for change

’bout time. All hail unicode.

UPDATE: This is wrong. It’s long been possible to have domain names like the one in the subject (which is my name in Japanese Katakana, BTW). The technical method that allows this (a ToASCII conversion algorithm) has been around for several years. I had the impression that this was becoming an official ICANN implementation at the root name servers. Not so. It’s been official for a long time. But only for certain top level domains. The only thing that is changing is now non-Roman alpabet TLDs (top level domains like com, net, edu, org, jp and so on may be created. They were already possible in theory using the ToASCII method but ICANN had never approved any for actual use.

In short, this is a pretty boring story but the details of IDN implementation are pretty interesting. As usual, the Wikipedia page provides the best overview.

So, カークサミュエルソン.com is NOT possible but カークサミュエルソン.jp most certainly is. Not only that, it’s still available.

Executed Today

Thursday, October 29th, 2009

Wow. If you’re a fan of history and are interested in state justice (and injustice) and have a taste for the macabre (not incompatible with the previous two avocations) Executed Today is your new thing. This blog covered the state murder of Cameron Todd Willingham a year and a half before the excellent New Yorker piece.

There’s been a single execution in all of New England since 1960, in Connecticut. The large majority of executions are in the South, but particularly in Texas.

The most recent execution in the US was yesterday. Reginald Blanton was executed in Texas. There is some question as to his guilt.

I don’t know why we continue to “tinker with the machinery of death” in the words of Justice Blackmun. Really, it just seems so unwise.

The Atlantic Takes a Dive

Wednesday, October 28th, 2009

Hey, The Atlantic has lost it. At least for me. The evidence is in two parts. First, the flu vaccine. I kind of hate this topic. But I’m going to write about it anyway because it is upsetting me.

Until not many years ago I had never had the flu vaccine and didn’t really understand much about it. Maybe I still don’t but I think I’ve gathered this much – the flu vaccine, as vaccines go, sucks. It’s pretty hit and miss year to year because of inaccuracies in predicting what strains will be prevalent and it doesn’t help old people, who really need it, as much as the young and healthy (because it depends on a strong antibody response). But saying the flu vaccine sucks compared to other vaccines isn’t saying much because vaccines have contributed more to human health and happiness more than any other feature of modern medicine except perhaps antibiotics. The flu vaccine, while imperfect, is probably a really good idea. Certainly it is safe compared to getting the flu. It’s safe compared to leaving your house, for that matter. This topic upsets me right now for  few reasons, one of which I’ll share. This week I overheard a conversation between a mother of two young kids and a pregnant woman. The mother said she was going to the store after work to get some “Airborne” because there was no way she was going to let her kids get the flu vaccine. The pregnant woman concurred saying that she wouldn’t get it either even though her doctor really wants her to. Well, fuck. Her doctor wants her to get vaccinated for a very good reason – it could be because he’s a tool of the medical industrial complex but it’s more likely because pregnant women are much more likely to die from influenza than the normal, unpregnant population. And, yes, so are young kids more likely to die from it too. I’m not going to provide any references for that assertion because they are easy enough to find.

So, on to the stupid Atlantic article.

Does the Vaccine Matter?

“Tom Jefferson has taken a lot of heat just for saying, ‘Here’s the evidence: it’s not very good,’” says Majumdar. “The reaction has been so dogmatic and even hysterical that you’d think he was advocating stealing babies.” Yet while other flu researchers may not like what Jefferson has to say, they cannot ignore the fact that he knows the flu-vaccine literature better than anyone else on the planet.

The article paints Jefferson as a brave maverick fighting against conformity and complacency. It’s more likely that he’s kind of a crank. Or at least flirts with them. Two Science Blogs, by separate authors, do the take down.

Journalists sink in The Atlantic article on vaccines

There is nothing judicious about Jefferson, whose problem was described by one of my colleagues as “methodolatry,” the profane worship of the randomized clinical trial as the only valid method of investigation. In this case his evidence base isn’t even relevant, because we aren’t dealing with seasonal flu but pandemic flu.

Vaccination for H1N1 “swine” flu: Do The Atlantic, Shannon Brownlee, and Jeanne Lenzer matter?
Vaccination for H1N1 “swine” flu: Do The Atlantic, Shannon Brownlee, and Jeanne Lenzer matter?
Framing an issue as arguing that conventional wisdom is wrong and highlighting a couple of “lone voices in the wilderness” warning, Cassandra-like, of impending disaster represent a time-honored journalistic trope, not to mention a story structure that goes back thousands of years to, well, Cassandra at least. Add a healthy dollop of “skepticism” about big pharma and the government, and you definitely have a winner. I can see why the editors of The Atlantic bit.

Also, there is the pure goodness that is Mark Crislip writing on the efficacy of the flu vaccine. You don’t even need to read to enjoy Dr. Crislip – he’s fighting the good fight on his podcast Quackcast too.

This post is not what you think!!!

Tuesday, October 20th, 2009

Man, I’m trying to dig into the whole Super-freaking-nomics (misspelling intentional) climate change dust up and am feeling worn out. These guys, the freakonomics guys, play these games where logic and knowledge and analysis all get thrown around in the most unserious way. It’s maddening. Here’s what I’m talking about.

Who Causes Cyclists’ Deaths?

More than 52,000 bicyclists have been killed in bicycle traffic accidents in the U.S. over the 80 years the federal government has been keeping records. When it comes to sharing the road with cars, many people seem to assume that such accidents are usually the cyclist’s fault — a result of reckless or aggressive riding.

Who are these many people” who think bicycles are to blame in traffic accidents? You hear a lot about cars hitting cyclists but not a lot about it happening the other way around. The Freakonomics blog stands common sense on it’s head and then declares that the real answer isn’t the one you expect! I call bullshit. It’s just a stunt. There is nothing surprising about the fact that cars hit bikes.

Here is an example on the topic of climate change. Dubner is talking about how climate change will affect poor nations the most. That, perhaps, is true. The muddle comes at the end of this quote.

A Different Climate Change Apocalypse Than the One You Were Envisioning

In other words: the likeliest victims are, once again, the poorest people. Which means that if the relatively rich people who are currently most vocal about climate change are also the people who stand in the least danger, there may come a point where they realize that their concern is not so much an act of self-preservation as an act of altruism. Considering how impure much of our altruism is, that could be the most dangerous news of all.

Altruism is dangerous!@! More dangerous than global warming!! But the link, if you click through, says no such thing, of course. Rather, it tells us that altruism isn’t based on rational decision making. Not very shocking!!!

When the Freakonomics blog was new, I read it a bit. So, I was clued in to their climate change cluelessness long ago. Here’s a post I remember.

Are Man-Made Tornadoes the Answer to Global Warming?

This is probably too good to be true, but all you need is one big idea like this to work. If that happens, all the gloom and doom and real economic sacrifice associated with global warming becomes a small footnote in the history books. Technology and human ingenuity have solved just about every problem we’ve faced so far; there is no obvious reason why global warming shouldn’t succumb as well.

I’m a big fan of technology but who can seriously suggest that it has “solved just about every problem we’ve faced so far”? Also, we won’t have to make economic sacrifices because these geo-engineering projects, none of which have gotten past the fanciful idea stage, will be, um, free? How’s that?

These guys aren’t evil. They aren’t out to screw anybody. I think their problem is that they’ve developed this contrarianism-as-entertainment niche and they apply that thinking to every topic that comes their way. They are following their own noses instead of than following the facts.

New Seatpost

Tuesday, October 20th, 2009

My new seatpost arrived today. For this photo, I removed the top brackets which clamp onto the seat rails to show off the one-piece design of the post and crown. The post is slightly ribbed – there are very fine grooves on the surface. I presume this is to help prevent slippage in the seat tube. Or perhaps it’s just because it looks awesome up close.

I’m considering now that the seatpost may be the nicest component on my bike. Hmm.

Carbon Fiber Seatposts

Tuesday, October 13th, 2009

Carbon fiber has been increasing used in bicycle frames and components in recent years. It’s very lightweight and still reasonably strong. It also allows framemakers, on the high end, to create areas of varying stiffness by altering the direction of the weave. The area where the down tube, seat tube, and chainstays meet the bottom bracket can be make very stiff, for optimal power transfer, and more compliant in other areas to lessen road vibration.  That’s the theory anyway. There is a lot of marketing hype in the cycling world but there’s also a lot of hardcore bike engineering geekery. I find it credible to a degree. I have changed my mind about carbon seatposts, however.

Thomson, maker of fine aluminum seatposts and stems, has this to say about carbon:

Hoop strength refers to a materials ability to resist damage when clamped. Carbon fiber is notoriously weak in this regard. We feel it illogical to use a material that is not made for being clamped around its circumference in a seatpost. Clamping forces can lead to fiber shearing and/or delamination of carbon fiber.

I think this is precisely what happened in my case: I had raised my seatpost a bit recently after developing a bit of knee pain. It’s the place where it was previously clamped that failed yesterday. I’d ridden a few hundred miles after raising the post. No hard impact  was involved – I was cooling down on my way home when this happened. All I did was sit down after a standing climb and crunch.

I’m convinced. I don’t like buying throwaway stuff. I’d rather spend more money up front for parts that will last a long time. So I went ahead and bought a Thomson aluminum post. It’s lightweight, has good reviews from other cyclists, and has a lot of bling factor to boot. I guess I’m lucky I passed on the Jamestown Classic race yesterday. Having your seat fall off could be a bit of a hazard when going 30 mph.

Costs vs. outcomes, people!

Sunday, October 11th, 2009

Let’s face it. You don’t know shit about what’s wrong with the health care system and what needs to be done to fix it. You think it has something to do with the personal stories people tell about being denied coverage – greedy insurance companies getting between patients and their doctors. This is mostly bullshit.
Or you think it’s about socialism and long waiting lists. If you’re really a nutjob, by which I mean a Republican, you think it has something to do with radical left wing African American nazi abortionists. Whatever.

The reality is that it is mostly about economics. Don’t listen to personal anecdotes – look at data. Costs vs. outcomes. Competition vs. regulation. Inefficiency and waste. It’s all about money and it’s really important that the focus be on money.

This American Life gets it. Every so often, between all their shows on the travails of the upper middle class, this radio show knocks it out of the park. This is one of those times. Listen to it.
