It should be even easier than that.

Archive.org should archive everything, including the robot.txt contents, at each scan.

The content being displayed from the archive.org website itself however could then still honor robots.txt at the time of the scan, purely for "display" purposes.

This way changing robots.txt to block search engines would not delete or hide any previous information.
Also the new information would still be in the archive, even if not displayed due to the current robots.txt directives.

Although it would require more work to do so properly, this would potentially allow for website owners to retroactively "unhide" content in the archive in the past as well.
Proper in this case would require some way to verify the domain owner, but this could likely be as simple as creating another specifically named text file in the websites root path, with content provided by the archive.
That can be as simple as the old school "cookie" data like so many other services use such as Google, or as complex as a standard that allows date ranges specified along with directives.

But in any case, this would preserve copies of the website for future use, such as for when copyright protection expires.
Despite everyone having a differing opinion on just how long "limited time" should be in "securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries", no one who wants to be taken seriously can argue that this time of expiration must happen at some point.
Since the vast majority of authors make no considerations to protect our property, that task clearly needs to fall on us to secure.

Comment Of all the problems that needed $9 million... (Score 2) 169

...having too many credit cards in your wallet was not one of them. Can't say I'm surprised it turned out to be a scam. The latest crowdfunded crap I've seen being promoted on Facebook: some shysters trying to convince investors that a Samsung Tablet with VNC installed on it is a novel invention.

These days, crowdfunding seems to be less garage/backyard tinkerers, and more already wealthy con artists using it as an easy source of income. Can't say I blame them - if I had the means to promote and profit from some idiotic "invention", I'd probably do that shit too. Anybody want to invest in my solar powered vinyl player which automatically uploads your music to the cloud? I swear, it's going to be the next big thing!

tl;dr bitch bitch bitch--but to be honest--keep doing what y'all are doing; it's working.

Abstractions of abstractions of abstractions....you can't even see the first turtle from the top.

Yes, I understand we get some functionality for the price we pay--but it seems to be the way of the rocket--90% of your fuel is expended just accelerating your fuel.
I've got (lemme see...) 12 VMs on my laptop right now--just because things don't play nice with other things or customers want development in specific versions.
So--yeah--I have no illusions the complexity is going away.

But, for all the fancy crap, the functionality is basically the same: Operator touches the screen. Conveyor starts running and knife starts chopping.
I click "send". Couple seconds later my Dad gets an email.
Things were so much simpler back then, and we don't seem to have any real advance in function.

Of course, I don't have to install a separate print and screen driver for each program.
And spend hours tweaking the EMM386 stuff in config.sys.
and...and...and...

Well, that's the thing about nostalgia--some of our fondest memories never happened.

RP-1/HTP works fine. The British Black Knight had over 20 successful (suborbital) launches with it, and the later Black Arrow, whose first two stages were RP-1/HTP, put the UK's only independently-launched satellite into orbit, back in 1971.

Given the number of first-rocket attempts which have failed (sometimes explosively) because of things like frozen LOX valves, going non-cryogenic has a certain appeal. Especially since they can pretty much stockpile the things in a fueled state for rapid launch.

Any rocket fuel is likely to kill you if you look at them funny. Some more so than others, sure, but nobody is using liquid ozone or FLOX (liquid fluorine-oxygen) as an oxidizer any more either. (Or worse. See the book "Ignition!" for a fun look at early rocket fuel experiments.)

And for what it's worth, the mass ratio of an aluminum beer can (12 fl oz size) is a hair under 28:1. ;-)

Comment Re:Revolutionary Rocket aka aerospike engine (Score 3, Informative) 44

You're confusing aero spike engines with simpler (but heavier) spike engines.

In an aerospike, aerodynamic forces (often with the assist of gasses injected at the base of the engine) form the "pointy" part of the spike, so there's both the lighter and easier to cool aspect. Also known as a plug-nozzle, but the latter are usually (a) circular and (b) even shallower than this linear aerospike.

Spike nozzles (circular ones) have also been flight tested, but yeah, the tail of that spike is heavy -- and also not what you want if you're planning to reuse the vehicle, because it aggravates reentry heating. (Doesn't look like this is what ARCA is planning though, I guess they're just going for cheap and disposable. Maybe reusable will follow.)

NASA never had any problems with their X-33 aerospike, it was all down to the weird-ass V-shape fuel tank configuration.

Comment What in the actual fuck? (Score 1) 177

So, is this like how Barnes and Noble has a Starbucks inside? Or, is it more like how the local mall couldn't find enough individual shops to rent out the place, so they converted most of the bottom floor into a gym (ostensibly for exercise, not Pokemon)? Or, is this like when I ask the guy I think is a salesperson at Walmart to unlock the anti-theft case so I can buy something, but he can't help me because he's only there to hock DirecTV subscriptions?

The "new economy" sucks.
