Hopefully before next century, but yes. Past a certain distance from the sun (somewhere around the asteroid belt, or a bit further), solar cells don't do much for you, and uranium or thorium are hard to come by. Lots of deuterium-laden hydrogen, however.
If (when?) we get to the point of manufacturing things as complex as fusion reactors in space, we can go interstellar -- one Oort cloud object at a time, like the polynesian islanders in their canoes.
(Yeah, I'd rather have warp drives, but working fusion reactors are more likely.)
No. If you have physical access to a Mac, it is trivial to reboot it into single user (ie root) mode. No extra equipment required, and only as long as the boot time. Unlike other *nix systems, MacOS doesn't require that you login with the root password in single user mode. (Or didn't last time I tried.)
What this bug does is give the casual passerby root access without having to reboot, therefore making it less obvious that it was tampered with.
On the contrary. He'd read Dirk Pearson and Sandy Shaw's stuff, among others, and followed much of the advice. He was 84 when he died, not bad at all -- although we could have wished for more.
Problem with most anti-aging/life extension techniques is that they work best if started early (ie twenties). He was probably 50 when Pearson & Shaw's first book came out.
I read Jerry's science fiction back when he was writing for Analog Science Fiction magazine, and later had the opportunity to work with him at Byte magazine. Byte even flew me out to Chaos Manor to get him up to speed on their new BIX system, a computer conferencing system (a pre-Web forerunner to systems like/., Ars Technica, etc.) based on software I wrote. He invited me to a party where I met the likes of Larry Niven, Bob Silverberg and Poul Anderson.
I later worked with him, Niven, Anderson and a number of other writers, scientists and astronauts as part of the Citizens Advisory Council on National Space Policy. We (mostly he) helped get the DC-X project started -- reusable, vertical-takeoff-and-landing rocket technology that SpaceX built on for their Falcon launcher.
He inspired me to start selling my writing, both non-fiction and later fiction. In fact, by a series of events I won't go into here (but involving the Council and an International Space Development Conference) he led to me meeting the woman I later married. When we had twin boys, we briefly (very briefly) considered naming them Jerry and Larry.
His passing isn't a complete surprise; he was getting on in years and he had had health issues in recent years, but it is still sad to see him gone. My condolences to his family, who were all very gracious when I visited his home.
Courts generally interpret contracts as narrowly as possible.
Good thing the GPL isn't a contract, then. It's a license that grants permission to distribute somebody else's copyright code.
court is going to rule that the term is too broad and like violates Grsecurities civil rights.
Grsecurity has no right to distribute anyone else's code. If they don't like that term in the license, they don't have permission to violate the Linux copyright holders' rights. Grsecurity's civil rights are not affected at all.
Geez, this same stupid argument every time someone tries to violate the GPL. Sooner or later it sinks in that if they do manage to get the GPL struck down in court, they'll have to shut down their business or face a massive copyright infringement suit. At which point they usually settle.
Without that license, if you distribute someone else's GPL'd code, you are violating their copyright. You can't distribute something somebody else has a copyright on without a license from them.
Now, in other cases, a contract may grant a license. But a contract is not itself a license, and vice versa. Only the owner of a copyright has the right to distribute that work. Everyone else requires a license. The license does not confer a right, it grants permission.
(It's also possible to transfer a copyright, in which case the transferor loses that right. That requires paperwork to be registered with the Copyright Office.)
Your "if" evaluates to false. The (very) early universe expanded far faster than the speed of light. This is possible because it was spacetime itself expanding FTL, not something trying to travel through it.
I wouldn't be so sure that they will be cheaper to rent than it is to own a car.
Of course they won't be. Somebody has to own that car (ie, the car rental company) and they're going to want to make a profit on their investment. Per mile, it will always cost more to rent than to own.
Now, an individual might -- by restricting the amount that they drive -- not pay as much out of pocket for that car, because they're sharing the miles with other renters. And for some people that might make sense. But generally not for folks who don't live in extensive densely populated conurbations (aka, "targets", for those who remember the Cold War).
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.;-)
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.

More likely the real bug was in letting the users download these videos a part of their archives, instead of paying attention to the "deleted" flag.

Wait, what? He's married to his daughter?

"regarding the Dieselgate scandal"
It's been more than 45 years since the Watergate break-in. Can we give the "-gate" suffix a rest already?

Exactly. That's what he meant by "filing off the serial numbers". The characters, locations, actions and dialog are the serial numbers.
(He was also generally referring to works that would have been out of copyright, e.g. the classics.)
Systemd or not?
Fortunately, there are still Linux distros available that don't use systemd. I'll take sysv init any day.
No. If you have physical access to a Mac, it is trivial to reboot it into single user (ie root) mode. No extra equipment required, and only as long as the boot time.

Hey Bruce! Sorry that it's under such circumstances, but it's good to hear (if indirectly) from you again. Your post is spot on.

Why the hell does an init system need a built-in DNS resolver anyway?
Going from 1 threat to 3 is a 300% increase. Going from 1000 to 999 is a decrease. (Numbers arbitrary)
Guess which one I'd prefer?
Once is happenstance. Twice is coincidence. Three times is enemy action.
What's Microsoft's count up to now? ;)

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.

No one ever said that.
Sure they did. Lumpy said it in the post just above yours. I'm not sure I'd call him one of the wisest men in the country, but hey.
Who is this Juan, and why does everybody need to worry about his safety belt?
"It" is not only gender-neutral, it is also species-neutral and even animate-vs-inanimate neutral.
The latter two have a tendency to offend humans of whatever gender (or sex).
