The ASAP

…is finally coming around on Commercial Crew:

VADM Dyer also appeared to be against the notion of downselecting to one partner ahead of time, as has been intimated as a cost-saving option by some lawmakers.

“The thinking there is: If you need a house, why would you want to build two houses? Why not select one?” added the minutes. “VADM Dyer opined that it is a ‘very complicated house.’ The ASAP believes that competition brings the best of both providers to the fore.

“It also allows NASA to watch these two approaches and companies mature before making a downselect. The Panel stands foursquare in support of competition, as does NASA.”

It was also notable that NASA managers responded by stressing the ongoing discrepancy between the requested budgets for the Program and what has been appropriated.

With the two companies under fixed-price contracts, it was noted that it is important for all to recognize that if NASA does not receive the appropriations that it is counting on, it will have a very significant impact on schedule, and we will end up relying on the Russians beyond the 2017 target.

You don’t say.

Tulip Subsidies

A parable:

Higher education is in a bubble much like the old tulip bubble. In the past forty years, the price of college has dectupled (quadrupled when adjusting for inflation). It used to be easy to pay for college with a summer job; now it is impossible. At the same time, the unemployment rate of people without college degrees is twice that of people who have them. Things are clearly very bad and Senator Sanders is right to be concerned.

But, well, when we require doctors to get a college degree before they can go to medical school, we’re throwing out a mere $5 billion, barely enough to house all the homeless people in the country. But Senator Sanders admits that his plan would cost $70 billion per year. That’s about the size of the entire economy of Hawaii. It’s enough to give $2000 every year to every American in poverty.

At what point do we say “Actually, no, let’s not do that, and just let people hold basic jobs even if they don’t cough up a a hundred thousand dollars from somewhere to get a degree in Medieval History”?

I’m afraid that Sanders’ plan is a lot like the tulip subsidy idea that started off this post. It would subsidize the continuation of a useless tradition that has turned into a speculation bubble, prevent the bubble from ever popping, and disincentivize people from figuring out a way to route around the problem, eg replacing the tulips with daffodils.

(yes, it is nice to have college for non-economic reasons too, but let’s be honest – if there were no such institution as college, would you, totally for non-economic reasons, suggest the government pay poor people $100,000 to get a degree in Medieval History? Also, anything not related to job-getting can be done three times as quickly by just reading a book.)

If I were Sanders, I’d propose a different strategy. Make “college degree” a protected characteristic, like race and religion and sexuality. If you’re not allowed to ask a job candidate whether they’re gay, you’re not allowed to ask them whether they’re a college graduate or not. You can give them all sorts of examinations, you can ask them their high school grades and SAT scores, you can ask their work history, but if you ask them if they have a degree then that’s illegal class-based discrimination and you’re going to jail. I realize this is a blatant violation of my usual semi-libertarian principles, but at this point I don’t care.

Never happen. It makes too much sense.

[Afternoon update]

“College is not a commodity. Stop treating it like one“:

A college education, then, if it is a commodity, is no car. The courses the student decides to take (and not take), the amount of work the student does, the intellectual curiosity the student exhibits, her participation in class, his focus and determination — all contribute far more to her educational “outcome” than the college’s overall curriculum, much less its amenities and social life. Yet most public discussion of higher ed today pretends that students simply receive their education from colleges the way a person walks out of Best Buy with a television.

The results of this kind of thinking are pernicious. Governors and legislators, as well as the media, treat colleges as purveyors of goods, students as consumers and degrees as products. Students get the message. If colleges are responsible for outcomes, then students can feel entitled to classes that do not push them too hard, to high grades and to material that does not challenge their assumptions or make them uncomfortable. Hence colleges too often cater to student demands for trigger warnings, “safe rooms,” and canceled commencement speakers. When rating colleges, as everyone from the president to weekly magazines insist on doing nowadays, people use performance measures such as graduation rates and time to degree as though those figures depended entirely upon the colleges and not at all upon the students.

What a government-driven disaster.

Climate-Change Communications

moving beyond certainty:

The strategy of hyping certainty and a scientific consensus and dismissing decadal variability is a bad move for communicating a very complex, wicked problem such as climate change. Apart from the ‘meaningful’ issue, its an issue of trust – hyping certainty and a premature consensus does not help the issue of public trust in the science.

This new paper is especially interesting in context of the Karl et al paper, that ‘disappears’ the hiatus. I suspect that the main take home message for the public (those paying attention, anyways) is that the data is really really uncertain and there is plenty of opportunity for scientists to ‘cherry pick’ methods to get desired results.

Apart from the issue of how IPCC leaders communicate the science to the public, this paper also has important implications for journalists. The paper has a vindication of sorts for David Rose, who asked hard hitting questions about the pause at the Stockholm press conference.

It’s a good, and necessary first step.

OK, Different Computer Question

I’ve got her machine set up as Windows native, installed on SSD. Her old Windows drive, with her old files, is hooked up to it. She can see it fine from Windows. But while she was using Linux, she’d been writing to an LVM drive, which was originally a backup, but now has some changes on it from the old drive.

I’m running Fedora as a virtual machine, and it seems to be running fine (so far). I’ve attached the old Windows drive to the physical machine, and it shows up in Nautilus and other file managers. But when I try to access it, I get a message that it’s an NTFS drive with problems, and I can only mount it read-only. It suggests I repair.

So, is this caused by the fact that its already mounted and in use by Windows? Seems a little strange, since the virtual machine probably wouldn’t know that. Windows doesn’t have a problem with it. Bigger question: Can/should I try to repair it as an unmounted drive from the virtual machine using e2fsck? That is, does e2fsck repair NTFS drives? And what is the risk if I don’t attempt to back it up first?
