They try to tell SpaceX how hard reusability is.
I’ve got to run some errands, but I’ll have some comments later. Briefly, though, Dumbacher’s comparison with the SSME is pretty much worthless.

as Electronic Frontier Foundation’s Parker Higgins convincingly argues, it’s not the justices’ lack of personal experience with technology that’s the problem; it’s their tendency to not understand how people use it. Returning to Justice Roberts’s concerns about villains with two phones: if he is in fact unaware of how common that behavior is – he certainly didn’t watch Breaking Bad – then that suggests a major gap in his understanding of society.
This lack of basic understanding is alarming, because the supreme court is really the only branch of power poised to confront one of the great challenges of our time: catching up our laws to the pace of innovation, defending our privacy against the sprint of surveillance. The NSA is “training more cyberwarriors” as fast as it can, but our elected representatives move at a snail’s pace when it comes to the internet. The US Congress has proven itself unable to pass even the most uncontroversial proposals, let alone comprehensive NSA reforms: the legislative branch can’t even get its act together long enough to pass an update our primary email privacy law, which was written in 1986 – before the World Wide Web had been invented.
So the future of our privacy, of our technology – these problems land at the feet of a handful of tech-unsavvy judges.
Kind of scary.
“Robert Heinlein, call your office.”
Would that he could. I wonder if it would be possible to get the same effect with stem cells from your own body?
I’ve asked this question before, but don’t recall if it was ever resolved. Just before the Shuttle flight one pad rat was killed and others injured from hypoxia when they entered an area with a nitrogen purge:
When the workers stepped into the compartment, they would not have smelled anything peculiar or have had any other warning that they were entering a deadly area. All five men were reported to have passed out almost immediately, and soon afterward they were evacuated from the compartment. Dies Aboard Helicopter
John Bjornstad, a 50-year-old senior chemical technician, died aboard a helicopter that was carrying him to a hospital in nearby Titusville. The medical authorities explained that the nitrogen itself was not poisonous – it makes up nearly 80 percent of ordinary air – but such an exposure deprives a person of all oxygen. He dies of what is known as hypoxia, which is lack of oxygen.
Seems like a pretty painless way to go to me. Why not just a gas chamber and run nitrogen through it until brain death?
Joe Pappalardo: “Why I feel bad about them (sort of).”
Stem cells may make them obsolete.
Faster, please.
Why you should be one.
The danger of killing too many of them.
Rogozin is threatening to cut off US access to the ISS, on the same day that the House space subcommittee marks up a bill declaring that “safety is the highest priority.”
Idiots.
Matt Ridley says “no”:
I have lived among both tribes. I studied various forms of ecology in an academic setting for seven years and then worked at the Economist magazine for eight years. When I was an ecologist (in the academic sense of the word, not the political one, though I also had antinuclear stickers on my car), I very much espoused the carrying-capacity viewpoint—that there were limits to growth. I nowadays lean to the view that there are no limits because we can invent new ways of doing more with less.
This disagreement goes to the heart of many current political issues and explains much about why people disagree about environmental policy. In the climate debate, for example, pessimists see a limit to the atmosphere’s capacity to cope with extra carbon dioxide without rapid warming. So a continuing increase in emissions if economic growth continues will eventually accelerate warming to dangerous rates. But optimists see economic growth leading to technological change that would result in the use of lower-carbon energy. That would allow warming to level off long before it does much harm.
I made a similar point about nine years ago:
The only hope for the planet is to get more of it to operate on the principles of the market, and individual choice. There are two competing approaches. The first is responding hysterically to problems that won’t occur for many decades (Kyoto being a prime example) which will reduce current wealth to the point that if and when those problems actually occur, we won’t have the financial wherewithal to be able to deal with them. The second is to use those resources wisely, per their most productive uses (i.e., responding to market pricing) to create the wealth necessary to create new resources.
There are many things wrong with our current approach to such things (e.g., the fishery problem), but the nostrums proposed by most “environmentalists” (who tend to be socialists and command economists in green clothing, even if many don’t recognize that) would make things worse, not better. Headlines like that in the Guardian article, implying that resources are a static quantity, of which we’ve already used two thirds, are just the kinds of misinformation that lead to flawed policy decisions, and reduction of wealth, and ultimately reductions of “resources.”
The problem is that the environmental movement has been hijacked by socialists and others completely ignorant of technology and economics.
