In 1683, Hooke proposed a solution to the nonuniform rotary speed of the universal joint: a pair of Hooke's joints 90 out of phase at either end of an intermediate shaft, an arrangement that is now known as a type of constant-velocity joint.
The art of using a 400 year old invention, in ways it has been used for a very long time... interesting.

I've dropped the handset on more than one occasion, slammed it in fits of rage, etc...
Of course the old Western Electric phones didn't care... Sometimes I think the abuse made them perform better. They performed double duty as a bludgeoning tool, too, if people were hassling you while you were on the phone.
Funny how that works. When AT&T leased land phones, they made them like a brick shithouse to avoid service calls... Now if you break a (essentially) leased (mobile) phone, it prints money for them and the manufacturer.
I've never had a 'protection plan' for anything worth less than a car... the premiums for these sorts of things are terrible. Like $20k/yr car insurance.
This has been done since the 1920's and the dawn of talking film.
Back then the signal was from a light passing through film, and the receiver was a special vacuum tube - a "phototube". The plate is coated with.. Caesium and something else, that makes a minute voltage when struck with light. Then you boost it with a few more tubes and play it on a speaker - synchronized sound.
'modern' photomultipliers are a boosted version of this (many internal stages of gain, so much so that a single photon will fire it).
IBM made small arms for the American side. M1 carbines, IIRC... among other things.
If the nazis did one thing right, partnering with hugo boss might have been it. As much as I hate fascists, I have to admit that the black SS uniforms looked pretty sharp.
But yeah, war is a racket. Even the cold war, 'humanitarian missions' and non-war are big money for the military industrial complex. Wonder what sort of ROI they get on their lobby dollars. Quite the setup... Unless of course, you're the taxpayer footing the bill.
Feral pigs get fur via interbreeding with wild boars, AFAIK.
That's akin to saying - domestic dogs have floppy ears because stress, if you let a chihuahua loose in the wild, it turns back into a wolf. The subspecies has permanent changes, not just environmental things.
But yeah, pigs weren't really designed to eat corn.
You can hunt deer just fine in Canada. You just need to take a firearms safety test and fill out a form to get a licence before you can buy guns. (which involves a background check, cops checking if you've threatened your ex-wives and they think you will kill them, etc).
However, handguns, while legal, are essentially useless. You need to phone the cops before you move them from your house to the range, etc. So unless you live on a farm, they're more of a pain than anything.
The mental deal around guns here is different. Guns are tools for sporting and sustenance only. Even pointing a gun at a person is a criminal offence, never mind shooting them. (law enforcement excluded, naturally).
You can technically be allowed to carry handguns in areas of 'extreme wildlife danger' or something like this, but it is very uncommon.
I kind of think the laws might be a little too strong in some regards, but it's been pretty effective, and people can still hunt and such.
Yeah, I think rover should be independent - this is more of a movable sensor for the probe really, as opposed to some sort of autonomous rover... It doesn't need to carry it's own power source, or communications, etc.
lunokhod series was a real rover though, first, no less. I guess the progenitor of all of them.
There's a documentary called 'tank on the moon' about the development of them. It shows footage of them trying various mechanisms - some including this 'walker' style - but ultimately they went for wheels on them.
Soviets definitely got their probe on before the west, and probed repeatedly, both Mars and Venus.
The probes on Venus had really short lives, due to the inhospitable conditions.. lot of cash for a little bit of observations. (I think the longest living one made two hours? forget now).
Yeah, shaking your head will allow you to see pulsed/multiplexed stuff, but I'd think a few kHz is really stretching it. I wouldn't think much more than a couple hundred Hz at the most?
Guess it depends on the duty cycle too. I'd imagine 5% duty would be more obvious than 50% or 95% for a given (fixed) frequency.
Guess I'll have to write some LED blinkin' when I get home and see at what speed flailing the LED quits working. (yeah, I suppose speed of the person moving relative to the light matters, also - not to mention persistence of the phosphor, or filament, or (lack of persistence) for LEDs.)
I like using NC for images, and I think people are a lot more likely to release their images under this (without this clause they may be less likely release them as CC at all, and just keep them closed).
I really dislike that wikipedia won't accept NC stuff, though.

It's real goal was to transfer money from the American people to military contractors.
It would have been amazingly successful at doing that.
I heard he is going to dress up like the moon, and orbit around it a few times.
Then he will lead the moon home to it's rightful spot - in the perpetually fog shrouded wasteland below the arctic peaks of Zokov island.

ok. Not longer than humans
Calling it a moon rock is kind of cheating, as it's probably been on earth longer than humans have. (uh.. right?)
Moon rock makes me think brought by humans, or something like this. Really neat, though.

It's roughly two furlongs...
(~400m).

Seems kind of disingenuous to include aluminium smelters that use more power than a small city, in 'personal consumption'.
but yeah, per capita total consumption, sure.

I seem to recall that the cuyahaga(sp?) river caught on fire 10+ times before they did much about it, around the early 70s. Pretty sick, really.
So many tons of toxic shit dumped into the rivers and great lakes...

They certainly have a patent on not including standard features.
Perhaps they can get Lucas involved. Then it can leak oil and release magic smoke at the same time.
Mineral oil is generally used as a laxative, so unless they are cooling with vegetable oil, I'd advise against this. :-p
Mineral oil is combustible in the same way that wax, sugar, wood, etc, are. It burns, but it isn't flammable, as the flashpoint is way too high.
You need to hold it at a high temperature to sustain combustion (like a wick, for example).
I've always heard the (presumably apocryphal) stories of pigs eating trabants; they supposedly have a taste for them.
If they said goats, I'd might have believed it. :)

That's interesting. I live in a city, and so do most people I know.
I wonder if we're both suffering with some sort of selection bias. Hmmm... :-p

I would like to contribute photos to wikipedia, however I don't want Monsanto or Raytheon using them for an ad campaign. Something like this, anyway.

Yep, printing the body is neat, but wake me up when they print the drivetrain.
