Of course, despite the results, she gets “warned” by “nutritionists.”

CPU Fan
The noise is driving me nuts. It rattles and ticks, and sounds like it’s about to fail. It’s just a few months old. I pulled the cooler assembly off, and removed the fan, and replaced it with an older one. I kept the heat sink, because the older one was about half the size and cooling capacity. But the old fan makes similar noises. I’ll go buy a new one at Fry’s, but I wonder if something else is going on.
[Update a while later]
OK, it’s not the fan. I stopped it momentarily, and there was no change. The question is: What is it? I can’t figure out exactly where it’s coming from. I only have one physical hard drive hooked up, and it’s not in the case.
[Update a while later]
OK, I changed power supplies. It’s better, though the noise is still there, and it’s not coming from the power supply. Still can’t quite isolate it. It’s now more of a steady ticking. It was doing it at 2 Hz or so, and now sounds like maybe 10, and not as loud.

This makes me wish I had a stethoscope.
[Sunday-afternoon update]
OK, got a stethoscope. The sound is not coming from anywhere or anything on the motherboard. I only hear it when I touch the case itself, and it seems to be being transferred through the metal. Still no clear where it’s coming from.

[Update a while later]
I picked the case up off the desk, and the sound changed slightly. I set it back down, and it’s changed a little again. But whatever was rattling is still rattling. I feel like I may have to pull the board and reinstall. Part of the problem is that the front edge of the board doesn’t have much support, due to configuration.
[Monday-morning update]
OK, when I push the case away from the motherboard, it gets a little quieter.
[Early afternoon update]
OK, starting to think it is supernatural. I tried recording it, so people could hear what I’m talking about, but nothing came out. It was like that old tape in The Sixth Sense. But I upped the mike gain, and aimed it better (it’s my headset, which is pretty directional), and now you can hear it, if you crank up speakers. It’s about a 3Hz resonance.
[Wednesday-afternoon update]
I FOUND IT!
There is a huge case fan in the front that I had previously been unaware existed. It turned out to be impossible to R&R, due to being trapped behind a riveted drive cage. So I just unplugged it. The bad news is that I now know how loud my PSU and CPU fans are. But it’s still a huge improvement. White noise instead of rattling.

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.
The Court “Victory” For The EPA
This doesn’t sound like a huge legal victory for the administration. It only postpones an actual ruling until later this summer.

The Senate NASA Mark Up
The Space Access Society has a legislative alert, to try to fix the budget on the Senate side, than fix the whole thing in conference.
How Much Money Would It Take To Launch Free Enterprise Into Space?
Some thoughts from Sam Dinkin over at The Space Review, with a plug for the Kickstarter, which has slowed since the burst last week. About half way to the goal, with a little over half the time left. Spread the word, at Facebook and other places, if you haven’t already.
Climate-Change Communications
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.
