Pain In Childbirth
Can be reduced with Vitamin D?
News I can’t use, but perhaps some of my younger female readers can.
Safe Is Not An Option: A Review
Finally, someone at NASA is willing to take the book seriously enough to critically review it. Obviously, I will respond at some point (TL;DR version, he cherry picks and ignores much of what I have to say, but that’s to be expected, given his NASA-centric viewpoint), but it’s a bad week between taxes and ISPCS. Anyway, despite my disagreement with the review itself, I’m sincerely grateful to Mr. Fodrocci for finally acknowledging the book’s existence, rather than (as much of the industry, including IAASS, has) pretending it doesn’t exist and hoping it will just go away.
Sierra Nevada’s Bid
Although the document praises Sierra’s “strong management approach to ensure the technical work and schedule are accomplished,” it cautions that the company’s Dream Chaser had “the longest schedule for completing certification.” The letter also states that “it also has the most work to accomplish which is likely to further extend its schedule beyond 2017, and is most likely to reach certification and begin service missions later than the other ‘Offerors’.”
Discussing costs, Gerstenmaier says that “although SNC’s price is lower than Boeing’s price, its technical and management approaches and its past performance are not as high and I see considerably more schedule risk with its proposal. Both SNC and SpaceX had high past performance, and very good technical and management approaches, but SNC’s price is significantly higher than SpaceX’s price.”
Touching on why Boeing received a $4.2 billion contract, versus $2.6 billion for SpaceX, he adds “I consider Boeing’s superior proposal, with regard to both its technical and management approach and its past performance, to be worth the additional price in comparison to the SNC proposal.”
Given how subjective such evaluation processes are, it’s not an implausible story.
Is There An Open-Source Doctor In The House?
OK, so I installed Gnucash on my machine last week, and it worked like a charm. I rebooted over the weekend after a yum update (which included a kernel rebuild I think) and now when I try to load the program, it crashes, with this response:

Any ideas from anyone what the problem might be? I’ve tried uninstalling/reinstalling, with no joy.
[Update a few minutes later]
Someone else seems to have the same problem, or a very similar one. I’ve emailed Mssr. Villemont.
Also, I’ve come up with a temporary fix to let me get taxes done. Skrooge seems to be able to import the data. It’s more of a personal finance app than for business, but it will let me do what I need to do until I get Gnucash fixed.
[Update a few minutes later]
Great. I can import my personal finances, but it fails when it tries to bring in the business books.
[Update a while later]
Good news. I deleted the file recommended at that page, and Gnucash seems to load properly now.
Five Years After Augustine
James Dean has an interview with the man himself.
This is the essay I wrote the previous summer as an input to the committee.
The Chairman Of The House Science Committee
“If Orion could provide a redundant capability as a fallback for the commercial crew partners, why is it necessary to carry two partners to ensure competition in the constrained budget environment?” Smith asked NASA Administrator Charles Bolden in an Oct. 7 letter co-signed by Rep. Steven Palazzo (R-Miss.), chairman of the House Science space subcommittee.
So as a bonus, the chairman of the space subcommittee is an idiot, too.
The country’s in the very best of hands.
Bias In Academia
…is destroying scientific integrity:
OK, it’s not exactly a “Sopranos” plot. But it’s pretty shady for the world of higher education. Chen went to great lengths to make up fake email addresses and even assume the names of other scientists to write approvingly of his own research.
In a sense, though, he was just exploiting the deep flaws of the peer review system. The academy has become a kind of club where friends give friends flattering assessments of research, which essentially guarantees promotions and tenure.
Here’s how the former editor of the British Medical Journal explained peer review:
“The editor looks at the title of the paper and sends it to two friends whom the editor thinks know something about the subject. If both advise publication the editor sends it to the printers. If both advise against publication the editor rejects the paper. If the reviewers disagree the editor sends it to a third reviewer and does whatever he or she advises. This … is little better than tossing a coin.”
But it’s not just the clubbiness of academia that is to blame. There is such ideological uniformity in the ivory tower that no one ever questions the important assumptions behind anyone else’s research.
Gee, where have we seen that sort of thing before?
I’d note, though, that contra the headline, it’s not a “liberal” bias. It’s a leftist bias.
Of Machines And Men
An interesting interview with Robin Hanson on brain emulation, AI, and the flaws of humanity.
Firefox
Great. Now not only is it refusing to restore tabs after it crashes (even though that’s what my preferences tell it to do), but this morning it came to with total amnesia of every page I’ve ever visited.
[Update Monday morning]
OK, I’ve installed Pale Moon 24.6.0, which seems to be the most recent version for which there’s a Linux tarball. It seems to run quickly so far, but I haven’t done much with it, or opened many tabs.
