Comment Boneshakers did not have pneumatic tires (Score 1) 71

They were boneshakers because they didn't have pneumatic tires. This is not true of a modern bicycle, and we also have far more understanding of mechanical systems and materials, including wood, now.

It is a widely perpetuated myth, mostly by bicycle frame makers who are attempting to get you to spend gobs of money on special designs, frame materials, etc that are "vertically stiff and horizontally compliant" (this phrase is now such marketing cliche it's mocked a lot)...that road bicycle suspension happens in the frame. It doesn't/shouldn't. It happens almost entirely in the tire/tube; when you go over a bump, the rest of the tube+tire stretches slightly to absorb the impact, and then contracts back. Some suspension also happens in the wheel; a wheel is quite strong in part because the spokes and rim both have some give to them.

Just as with cars, the most effective suspension is the one that has the least unsprung weight. So for example, high performance cars often have suspension and brake components made out of high-strength-for-weight materials, but in general, car manufacturers try to keep the weight of the suspension down.

On a bicycle with a properly sized and inflated tire for the rider's weight and road conditions, there is very little unsprung mass

Comment Why are you a corporate shill? (Score 5, Interesting) 111

Why did you, after college, attend the National Journalism Center, a corporate-funded program created to counter the mediaâ(TM)s alleged âoeanti-business biasâ?

Why, as someone who is half-Jamaican, have you repeatedly associated yourself (and apparently continue to do so) with the white supremacist organization EPPC, which fights activists for economic justice?

Why did you write for American Spectator, which churned out anti-Clinton conspiracy theories?

Why did you recycle tobacco industry propaganda and quote lobbyists for Washington Post articles you "wrote"? Why did Phillip Morris consider you, according to their internal documents, to be a "friend" who could be counted on for pro-tobacco-industry stories?

Why did you clearly promote drugs for treating ADHD in kids, in which you heavily quoted researchers who were paid heavily by the pharma industry?

Why did you cite a pharma-industry cited study and defend the industry when it was attacked for high drug costs?

Why did you blame the victims in the Enron collapse, defending executives who committed gross fraud?

Comment projectiles are a reasonable concern (Score 1) 406

I do high performance driver education events, and you're required to empty the car of everything not bolted down to it - everything comes out and goes into a box that you leave in the pits. Video cameras have to be tethered (because tripod mounts in traditional video camcorders are designed to break off if they're stressed too much.)

Anything not bolted down can become a projectile.

Lot of people don't think about this with their cars, but at least then, you're by and large only placing yourself, and a limited number of passengers who chose to ride with you, at risk.

Comment brilliant way to hide the genuine bad reviews, too (Score 1) 249

Pay no attention to the fact that what they're really doing is strongly diluting the actual poor reviews.

Honestly, the FAQ on their website makes them sound like complete fucking assholes. You don't have to bend over backwards for customers, but you really don't need to go around insulting the hell out of them.

Comment One every 8.5 days, actually (Score 1) 51

There aren't "stories every day" about Tesla, but every time there's a Tesla story, there is someone bitching and moaning about "all" the Tesla stories.

There have been 30 stories since January 1st - that equals about one story every 8.5 days.

You can count yourself, if you like. They do get clustered a bit, probably because when one piece of Tesla news hits, everyone starts paying more attention to Tesla related topics.

Comment "more than a year" = "immediately"? (Score 1) 174

There's a problem and they're handling it immediately and responsibly,

Uh, these drivetrain failures have been happening for at least a year. Google around and you'll see reports of failures around early 2013.

Edmund's Tesla has had the drive unit replaced FOUR times since they bought it last year.

Comment Yes, for repeater modules. 3000-4000VDC (Score 2) 103

Transatlantic fiber optic cables have repeater modules spaced along the cable to re-boost/time optical signals. They're powered off several thousand volts DC; 3k-4k.

Comment Cherry picking one's evaluative criteria (Score 1) 409

Cost is not the only consideration. It also by and large doesn't matter - environmental damage does. And build time.

Nuclear power plants can only be built so fast...I believe the chief restriction at the moment is how fast the containment vessels can be manufactured, and there's already a backlog.

What's frustrating is that we're pouring billions into fusion research with virtually no evidence of payout, instead of going with the solutions we have today, and then working on fusion once we've stopped fucking over the planet quite so quickly.

Comment Re:It wasn't his fault (Score 0) 127

Haruko Obokata was the lead researcher on those, and also the person responsible for fabricating the research results. Sure, his name was on it as a co-author, but that sounds more like the result of office politics than actually believing what she was publishing.

"Who's listed as author and in what order" is full of politics and bargaining. It's extremely common for first author to be a PI (faculty member or head of a group/lab) simply because the research happened in their lab and the actual primary researcher did most/all of the work.

Sometimes one researcher gets "scooped" and in exchange for providing help/data, gets authorship on someone else's paper as a sort of last-ditch attempt to get something out of their work.

Comment they will not release the note (Score 1) 127

Especially in a country like Japan where suicide is a huge problem, the note's contents will never be released.

Reporting on suicide has serious ethical consequences, and revealing the contents of the note means others will see suicide as a valid way to bring their ideas, grievances, or innocence to public light.

In most cases suicides are not reported, and even if they are newsworthy, generally the suicide nature is downplayed as much as possible.

It's one of those really sucky problems that's hard to deal with. Few really realize how much of a problem it is, but bringing awareness often makes it worse. One of the many things insidious about mental illness.
