I thought there were some existing parametrics for the savings in mass fraction for a stage or a lander launched dry (versus wet), but apparently not. Is there anyone out there who whomp up a simple system in AutoCAD or Solidworks? Say 50,000 lbs of LOX/Hydrogen, launch acceleration 6 gees?
Can anyone figure out why /home is mounting read-only at boot?
Here’s my fstab:

OK, clearly the disk is getting corrupted. I put in a file check option in the fstab, and it (temporarily) mounted it read-write at boot, but after working a while it became remounted read-only.
It’s not an argument for drug prohibition; it’s a demonstration and consequence of the failure of drug prohibition.
Four questions men should ask when selecting a college:
Since most college handbooks now define sexual assault broadly to include pretty much everything, one’s best bet is to avoid sex in college altogether. Colleges have enacted policies that allow non-students to bring accusations against students, so dating off campus isn’t safe either.
There’s really nothing that can be done to protect oneself from an accusation in the current climate. Sorry to sound so dire, but when a school puts up posters suggesting that even a sip of alcohol renders a women unable to give consent, things have gotten dire.
…I apologize if this seems like fearmongering, but college campuses are no longer safe for students accused of sexual assault. Due process rights have gone out the window because, activists tell us, this issue is so important that draconian measures must be taken. Their message is clear: Due process is fine and dandy for criminal courts, but this is a college campus, damn it, due process has no place here for those accused of felonies.
This is all making on-line education look better and better. And once again kudos to Ashe for being all over this beat.
This is my shocked face.
As someone noted on Twitter, this is the equivalent of leaving a new Mercedes out on the street with the key taped to the outside of the windshield.
I’ve been looking forward to this. Some formerly classified documents from the Apollo era have emerged.
I think they should be shunned and punished for being the bigots that they are.
Thoughts on his suggested reading list:
Ideological diversity in science fiction and fantasy was a given in the seventies. We are hopelessly homogenistic in comparison to them.
The program of political correctness of the past several decades has made even writers like Ray Bradbury and C. L. Moore all but unreadable to an entire generation. The conditioning is so strong, some people have almost physical reactions to the older stories now.
All part of the reason that I don’t read anywhere near as much SF as I did as a kid.
Some perennial thoughts from Instapundit (and Jim Bennett).
I agree that Columbus gets too much credit, and I don’t disagree that his behavior was depraved by modern lights. But the Carib Arawak were hardly the noble savages that the SJWs would have us believe. They had themselves subjugated the Taino, killing, raping, assimilating, into a brutal patriarchal society that practiced human sacrifice and, by some accounts, cannibalism. So it’s amusing to see all the whining about Columbus in that context.
Gennifer Flowers is back:
Asked what she thinks of Hillary’s candidacy and her platform focusing in part on women’s issues, Flowers began by explaining, “You know, people criticize me for talking about her because I had an affair with her husband.”
“And I don’t blame them for that,” she continued. “I understand that. I understand that they can be mad at me. I get it. I accept my responsibility. … But she’s never accepted her responsibility at being an enabler. She’s been an enabler that has encouraged him to go out and do whatever he does with women.”
“Woman’s rights. Ha!” Flowers retorted. “I personally have worked my tail off to get where I am in the entertainment business, which has not been easy since the Clinton scandal, by the way. … Hillary never put up a shingle and worked for her clients and built her clientele. She always got things on the back of her husband. … I think it’s a joke that she would run on women’s issues.”
…Klein referenced an interview from this past week in which Matt Drudge of the Drudge Report asked on Alex Jones’ radio show, “Why aren’t we seeing Hillary’s lovers? … Where’s the cover-up on this? … So many issues that are suppressed on a daily basis.”
Listen to Part 2 of Gennifer Flowers talk with Aaron Klein:
Affirming comments she made in 2013 to the Daily Mail, Flowers replied to Klein, “I know that Bill acknowledged to me that he was aware that she had a propensity for women and he didn’t care.”
“I’m not saying that she is a lesbian, but he acknowledged that she, as we say down on Arkansas, took a liking to women.”
Like Drudge, Flowers also asked, “Why something hasn’t come out on that? That’s amazing.”
I wish it were. I knew about it twenty years ago.
I blame Hillary for this. If she weren’t such a power monger, we wouldn’t have to go through all this again. This time, the gatekeepers are gone, and it will come out.
