That's a great way to lose your ACLs and xattrs including SELinux contexts and exe capabilities. The strings "attr" and "selinux" are not present in "man cpio" in RHEL6.
I used cpio on advice to move my installation from an HD to an SSD in Arch and it tossed all my capabilities attributes. Suddenly, ping would only work for root. It also reset the mod times on all my directories (files were preserved).
tar and rsync will do it right, though. In the version of tar from RHEL6, creating an archive:
--selinux save the SElinux context
--acl save the ACLs
--xattrs saves all user/root extended attributes including ACLs and SELinux context You can output the data from tar to stdout, piping it into another tar command to extract it to a different desitnation. For the extraction, no special switches are necessary to include the extra stuff archived.
In the version of rsync included with RHEL6:
-A preserves ACLs
-X preserves extended attributes including SELinux context
Note: I haven't personally verified the results in detail, but I sure as hell know from experience that cpio sucks donkey balls at this point.
Back in ancient history, cpio could copy stuff nothing else could (notably "special" files such as device nodes), but now the opposite is the case. The special files don't really matter any more, with udev and the like building them on demand.
When the justice system is no longer interested in enforcing the clear spirit and intent of the US Constitution
Are you kidding? Never mind the spirit and intent. They are violating the PLAIN PAINSTAKING WORDS of the Constitution! What we have is a system infested with maggots from top to bottom. These maggots either don't quite have the power (yet) or the inclination to actually change the Constitution, so they are cynically just altogether ignoring that piece of paper. The safeguards, such as the Supreme Court, to curtail such tyrrany are still in place, but they themselves have become just a part of the general infestation of maggots.
Add to that the level of care and dedication of the voting public to the ideals surrounding the establishment of their shining Camelot - it is about on the level of a mass of cockroaches.
If this state of affairs were fiction, no one could suspend their disbelief far enough to get any enjoyment or edification from it. No one would believe a whole nation of voters would ever put themselves in this situation, or having done so by some incredible sequence of unintended consequences, that they would continue putting up with it.
Star Trek would have needed a considerably bigger budget to have all the actors suspended on wires all the time to simulate zero gee. It's pretty difficult and demanding to give a convincing illusion.
Also with no controlled gravity field, changing warp speed would have had to be a very slow process, and the they would have had to show everyone taking to restraints every time the speed or direction was varied.
Star Trek was much less lame than crap like Star Wars or 99% of all productions involving space travel. Just how do you maneuver in space? Certainly not with wings and aerodynamic surfaces like a Tie Fighter! Then there are the insultingly stupid sound effects usually present where there is NO MEDIUM to carry sound. I know Star Trek exterior shots had a swishing sound, but I always considered that an artistic license to satisfy viewers who had little understanding of science.
2001 got it all stunningly, and practically uniquely, right.
There is no such thing as centrifugal force; only centripetal force. It takes a force (gravity or mechanical connection) to keep an object accelerating at a constant right angle to its path as a circular path demands.
What is thought of as "centrifugal" force is actually nothing but inertia.
Because it costs a significant amount of money to come up with these things in the first place. It does not cost a significant amount of money to copy them though. The result is that by elimination of dominated strategies, the best strategy in a world without patents is to not actually come up with anything new, but instead to just copy what everyone else is doing, as it gets you the same result with much lower cost.
That's not something the government wants to promote, for obvious reasons.
A spectacular example of backward thinking. If the government took its grimy hands off, it wouldn't be PROMOTING anything; it would remove an artificial suppression of free trade.
Look up "design patents". They are completely different animals from "utility patents". There are also abortions called "plant patents" (yeah, plant as in green growing thing), and "defensive publications", the latter now superseded by "statutory invention registrations". See this.
The court is doing its job. If a design patent is infringed, what else can the court do? The contemptible lunacy of design patents is on the heads of the legislature.
So fucking what? Yes, I said it. So what if Company B makes something that has a look and feel like Company A's something? Why should any benighted festering authoritarian hellhole stick its nose in and hinder competition and betterment?
Not really. Casting is a LOT more like 3D printing than extruding is. Both casting and 3D printing are additive and arbitrary shaping. Extruding (and forging) is neither additive nor subtractive, and is only 2D. Machining is subtractive, but it is 3D.
Did you never get instructed in operating a manual transmission? Starting on a hill without rolling back is what the handbrake is for. It can hardly be accomplished absolutely reliably without using the handbrake, but if you do use the handbrake there is but little drama or trick to it.
If you're stuck with a piece of crap manual transmission car that has a foot pedal parking brake, well, bad choice. You'd never get me in one of those.
Yes, an automatic is still much easier in the hill situation, and if you train yourself in proper left foot braking it is also safer, because you can cover the brake with your left foot a fraction of an inch above the pedal during situations that look like they could turn dicey fast.
To forestall someone objecting to left foot braking, note I said proper technique. With proper technique you never ever ride the brake, and your left foot is trained to use the right amount of pressure.
2) Anyway you look at it, not everyone has the same build. A great many cars have tilt and telescoping steering wheels. Essentially all of them have fore-aft driver's seat adjustment. Maybe more of them should have adequate driver's seat vertical adjustment for the ladies who cant see over the wheel, and apropos the current discussion, maybe more of them should have adjustable pedal separation.
3) If the objection is that everybody can see where the steering wheel is adjusted, but nobody stares at the pedals to check their position when they get in the car to drive it, you could program the car so the starter is only enabled after the driver cycles the accelerator, brake, accelerator, brake.
4) Yes, I realize everyday things will never work rationally enough to pleae me.
Half-life is half-life; there isn't a process we can use to change that
OK, to begin, the following is simplified to skip some points of extreme nuisance, and to be suitable for non nuclear engineers (like me).
Radioactive decay isn't as simple as one might be forgiven for thinking given the simplistic concept "half-life". You might ideally start off with a pure form of a single isotope of a single element. In practice, you never do. Reactor fuel as it goes into the reactor is about 5% U235, 95% U238, with traces of other elements and isotopes. When it comes out of the reactor, it is a lesser percentage of U235, still a bunch of U238 left, plus a bunch of plutonium and a witch's brew of other isotopes of elements resulting from the nuclear "cooking" in the reactor involving neutron bombardment.
But for simplicity, let's take an imaginary bunch of U235.
The U235 decays to Th231 in a decay process with a half-life of 704 million years The Th231 decays to Pa231 in a decay process with a half-life of 25.5 hours The Pa231 decays to Ac227 in a decay process with a half-life of 32,500 years The Ac227 decays to 98.6% Th227 and 1.4% Fr223 in a decay process with a half-life of 21.6 years The Th227 decays to Ra223 in a decay process with a half-life of 18.2 days The Ra223 decays to Rn219 in a decay process with a half-life of 11.4 days The Rn219 decays to Po215 in a decay process with a half-life of 4.00 seconds The Po215 decays to Pb211 in a decay process with a half-life of 1.78 milliseconds The Pb211 decays to Bi211 in a decay process with a half-life of 36.1 minutes The Bi211 decays to 99.7% Tl207 and 0.3% Po211 in a decay process with a half-life of 2.15 minutes The Tl207 decays to Pb207 in a decay process with a half-life of 4.79 minutes The Pb207 is stable and hangs around for the balance of eternity
The first thing to realize is that an instant after the imaginary start with pure Uranium235, and continuing for many billions of years, we have a constantly changing mix of various isotopes of elements, shading from pure U235, and asymptotically approaching (but never mathematically quite reaching) pure Lead207.
The constituents of that mix are busy decaying all at their own rates.
But the individual decay rates are mathematical models. A tiny little bit of that U235 has already changed all the way to Pb207 within the first hour, and a tiny little bit is still stuck at U235 after some billions of years. The rate of each individual decay process averages out to the half-life given by the particular model for that process.
So to get all the way to the point: yes, you actually can effectively change the rate of transmutation of the stuff that comes out of the reactor. You can re-enrich it back to a sufficiently rich mixture of uranium and plutonium oxides (and do some other reprocessing chores, such as cleaning out the fission poisons so it's usable again) and put it back in a reactor. Or you can separate out the plutonium and put it in a nuclear bomb and that will transmute really fast if you set it off. After you take out the plutonium it is at least theoretiucally possible to re-enrich the remainder back to 5% U235 and put THAT back in a reactor.
Note that the process during reactor operation is not the same as the decay process. In the reactor, you can "use up" a substantial percentage of the starting U235 in just a few years, in the process "creating" a bunch of plutonium (more than one isotope!) where there was none.
The Flight 1549 Hudson Miracle was helped considerably by the fact that (1) there are no massive ocean waves in a river, and (2) people knew very precisely in real time where the event occured and were extremely close by to respond.
And plenty of space for submarines to hide in. Since Nautilus in the 1950s, aircraft carriers have been nothing but targets for nuclear submarines. Time after time the latter have proved they can move at will in the heart of a carrier battle group undetected.
Battleships had lots of armor but carried their own destructive charges with them, known as magazines. Many of them blew up spectacularly from a single hit.
Aircraft carriers also carry their own destructive charges with them (bigger magazines than any battleship). Supposedly their airplanes and defensive screen protect them, except both have shown themselves to be little better than magic incantations.
an apple is worth 1 dollar from year to year, not 1 dollar today, then 10 dollars next week
Actually, capitalism only works because inflation is built in. An apple that is $1 this year, under GOOD conditions, will be ariund $1.05 next year, $1.10 the year after, year after year after year. There are variations. And sometimes hyperinflation, when there are times an apple is worth $1 this year and $1 million next year. Don't be so sure hyperinflation won't hit your home.
See if any of these mean anything to you: Weimar Republic 1923, Bolivia 1985, Greece 1944, Hungary 1946, Ukraine 1995. I could go on. The list is long.
The last US aircraft carrier with any armor at all (and it was not even as thick as a main battle tank's) was designed in WW2 and retired decades ago. None of our naval vessels has armor. Something as shitty as the small craft that devastated USS Cole would blast a hole just as big in a carrier, only there are 20 times as many crew standing behind a shell of about the same thickness - essentially an egg shell.
