Comment Re:How much to re-create Apollo? (Score 1) 221

If you can get - for the same launch cost - not 70 tons, but 1400 tons to orbit, even if they are in 54 ton, not 70 ton lumps - it starts being really questionable what the benefit of the 'shuttle derived' heritage is buying you.

It stops being questionable when you stop comparing prices - and start comparing what you get for those prices. Splitting the payload increases the amount of parasitic mass, I.E. non payload mass such as the support systems the payload requires until joined up in the final assembly. Splitting the payload also considerably increases the total risk of the mission - both by increasing the number of launches required and by adding rendezvous, docking, and assembly steps not required by a unitary payload.
Seriously, while I can't and won't argue the SLS is a good idea - there's a lot more to the equation than simply price. My minivan is much cheaper than a full sized pickup truck, but nobody sober and in full possession of his senses would ever confuse one for the other. No sane person would ever send one to do the other's job.

How expensive would it be to re-create the Apollo program?

Outrageously expensive - because pretty much every piece would have to be re- or reverse- engineered, production facilities established and qualified, all of the production and part QA processes and procedures re-established and re-validated, etc... etc...

In other words, would we save $BIGBUCKS by building on what we have instead of starting nearly from scratch?

The problem is... there's nothing to build on. Apollo is over forty years in the past, and there's nothing left of it. Zip, zilch, NADA. Pretty much very manufacturing process has changed (they welded together parts we'd machine in one piece out of a single block nowadays for example). A good chunk of it's electronics were analog - and used very low part count IC's (for both digital and analog) that were manufactured using processes that haven't been used in decades. Etc... etc...

Beside which - what makes you think an Apollo-Saturn launch was cheap? In current year dollars, they cost over a billion a pop out of pocket. (I.E. not considering sunk costs or amortization.)

"Death to All Jews" one in particular is not remotely anti-semitic.

I don't know what planet you're from or what your native language is - but here on Earth, in English, "Death to All Jews" is about as anti-semitic as it gets.

But I do rather fear the consequences of proving Trump right, of validating the echo chambers of tens of millions of people who were right-leaning fence sitters until they saw the proof stack up that the mainstream media really is full of hysterical, baldfaced lies.

First, present me with evidence that they lied. (And I think that's the real problem here - you don't even begin to grasp what PewDiePie did and why it's objectionable.)

Comment Re:Never Fails (Score 2) 131

Someone comes up with an idea that's pretty good, is designed for people to work part time to pick up some cash, minimal regulations, etc. and it's a pretty good thing for everyone all around.

I think you're posting in the wrong discussion - because there's considerable regulation both when it comes to hiring labor and when comes to transporting paying passengers. Regulation that Uber has consistently tried to circumvent, first with their nonsensical "ride sharing" claims, then with their equally nonsensical "we're just a tech company" claims. The only people it's "pretty good" for are Uber's investors, because they collect all the profit and shove all the risk onto the drivers.

So much this. To take the actions he did, PewDiePie had to be either supremely ignorant of the world around him, or supremely egotistical (I'm so big they won't dare take any action against me), or both. (Or, well, an actual anti-Semite but that's also covered by the earlier cases.)

A poster elsethread is trying to make the case that he actually didn't mean it... But misses that "not meaning it" doesn't absolve of him of responsibility for actually doing it. YouTube and Disney rightfully don't care whether he meant it or not - because he actually did it.

Comment Re:Dogfish Head - Chateau Jiahu (Score 1) 109

In keeping with historic evidence, Dogfish brewers use brown rice syrup, orange blossom honey, muscat grape, barley malt and hawthorn berry. The wort is fermented for about a month with sake yeast until the beer is ready for packaging.

So you have evidence of the fermenting time? And the yeast strain? No, you don't. So, no, you don't have a historical beer. (And that's setting aside the fact that 'brown rice syrup' isn't brown rice. Etc... etc..)

The GPS in my Honda Odyssey also tries to eliminate left turns. I turned that feature off because it was sometimes doing a ridiculous amount of re-routing to avoid a single left turn.

But you aren't a UPS driver, you're going to a single destination. A UPS driver is going to multiple destinations, which means the algorithm can use a trick you cant's - sequencing destinations. What's a "ridiculous" detour to you is an opportunity to deliver package "B" while avoiding a left turn on the way to delivering package "A". UPS's algorithms don't just arbitrarily eliminate left turns, they sequence the route (and choose which truck which package goes onto) so as to reduce the need for left turns and reduce the total number of miles traveled per package.

Comment Re:If your personal emails are released... (Score 3, Insightful) 102

and there's nothing unprofessional in them, the more embarrassing some personal stuff may be the more sympathy you'll get from the public and against the hackers.

Hardly. The embarrassing personal stuff will be turned into evidence that the journalist is unprofessional - or at least undesirable. ("Scott Mediapersonality is into $kink, how can we trust him!".) The goal here, on the part of the hacker's Masters is weaponize the email - and that's terrifyingly easy.

"If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him."

Dig into my email, and you'll find nothing unethical... But you will find a lot of otaku/anime material. A couple of quotes from those emails, put into an article with plenty of fanservice and hentai screenshots... and there's a lot of people who don't know who'll willingly believe I'm a rapist, a pervert, a pedophile. Hell, if they really wanted to, my SCA emails could be similiary spun - "here's a guy who gives fealty to a King! How can he believe in democracy!".

Etc... etc...

People in general won't believe the facts. They aren't even interested in the facts. All they know and think is what their Masters tell them to know and think.

Comment Re:Who would sink a nuclear ship? (Score 2) 203

Nine nuclear ships have sunk at sea. None of them resulted in significant radiation release.

And precisely none of them were sunk under attack. (And two of them aren't even in the ocean any more - they are salvaged.) That's an awful thin experience base on which to make long term judgements.

Comment Re:Gratuitous speculation (Score 1) 216

I'm reluctant to decry the science behind that evidence, but I'm much more reluctant to allow prosecution on the grounds, "You should have had a heart attack and you didn't"

Why? How is this different from any other kind of evidence that shows a defendant's claim to be physically impossible? Say a defendant claims to have been thirty miles away from the scene of a crime - when eyewitness accounts place him a mile away five minutes before (or after) the crime?
