Comment Re:Overboard, Sad! (Score 1) 112

The ability for something to do damage depends on it's momentum, and that is highly dependent the mass and centre of gravity of the object as it applies force against something. You do a 1kg drone a serious disservice comparing it to an iron mallet. A drone is a complex shape and its weight is distributed over a comparatively large area. While crashing it will be taking a complex path to the ground. When comparing the likelihood of it killing you remember it's far more likely to be the same as a falling iron mallet, horizontally, hitting a person by the handle rather than the iron centre part. You're far more likely to get a bruise from the mallet's handle.

Not really. The primary cause of momentum is the acceleration from gravity which is essentially constant for a falling drone, air resistance is just a counter-force proportional to the velocity squared. That is to say, the reduction from air resistance only becomes significant when you're falling very fast. A skydiver has a terminal velocity of about 195 km/h, but already a high diver from a 30m height will be close to 100km/h. I know my buddy's DJI Phantom goes up to 120m by default, at that height you'll be at 90% of terminal speed. Unless it's extremely small or light like a feather or a coin, any object dropped from a big height is a lethal weapon. When the rotors stop the body of a drone is quite compact and holds a heavy battery, it'll fall pretty much straight down. You can see a good example of a drone coming down after a complete power loss here.

As for the actual impact the higher the velocity, the less it matters how it hits you or how soft or elastic it is, a stick of butter dropped from a skyscraper will still hit you like a brick. We have a pretty thick skull but the sheer momentum will be like being hit in the head with the full swing of a baseball bat, your brain will bounce around in there like the ball in a pinball game. Sure there are arguably worse things to be hit by, but for the most part we secure tall objects. There's falling coconuts and big icicles and such we can't fully control, but drones are a new threat in the hands of idiots. They're not very dangerous, but in the hands of idiots many things are dangerous.

Liver tastes like something that spent a lifetime filtering out crap for a reason, kidneys taste like they've been marinated in piss, etc).

Organ meats contain the highest nutritional value, actually.

These statements are not mutually exclusive. Organ meats have a high chance of contamination from environmental sources because of their function. If clean, they are highly desirable. If not, you should leave them to the sled dogs. They have shorter lifespans, and are less likely to suffer the effects of bioaccumulation.

Done it on a few cars, Civic, Mustang. The worst are A arms. Two bushings, in line.

Yes, that sounds like a massive PITA. I have no experience with such things. I actually let someone change my Dana 50 ball joints, the same guy doing the alignment on my F250. On my 240SX, all the suspension links were just simple stamped steel items with one thing on each end, maybe a bolt attachment in the middle (e.g. radius rod to the front suspension arm.) The bushing in the radius rod is about the size of a subframe bushing on a german luxo barge, i.e. massive. So that's going to basically last forever. On my A8, it's all cast Aluminum members, and it's all multilink so they are all simple except the main one on the bottom to which the goodies attach. So there are just no situations like that. On the other hand, there's also not a complete kit of poly bushings available for either end of the car. There's only one poly bush shy in the front, but I think there's only one bush available for the rear. On the 240SX at least you could go full-poly, except maybe the subframe where people tended to go Aluminum anyway. And I lost track of the number of Integras I blew off due to handling differences, so meh to Honda :) I went full poly front and full spherical rear, though... And kept rubber subframe bushes for street comfort.

Is there a legal reason SpaceX can't have a lottery for tickets? Seems like a good way to fund these types of things.

Well what do you do if you don't sell all the lottery tickets, is the lottery stuck? Normally the prize pool is relative to the total paid in, but either you get a seat or you don't. Also you might end up with people that for medical or mental reasons shouldn't be trapped in a tiny little space capsule for a week with no chance of assistance, sure you can disqualify them in the terms and conditions but the whole "my number came up, but I was refused" bit would be negative PR. And it's just one lucky winner, in a regular lottery people like to win a little now and then while they hope for the jackpot. The rest will really be trinkets by comparison.

And I think this is still just a joyride, not a life changer. You take a fling around the moon and then you're right back to where you were, sure it's for space nerds but hardly the mass market appeal an ordinary lottery has. I think it would be totally different if it were say a ticket to Mars. That's the kind of thing you could probably make a living off afterwards, just from selling interviews and speaking engagements and such. Then again you'd probably want to be more selective in the selection process so... I mean it would be cool, but I understand why SpaceX wouldn't do it. And it's easy to get their lottery confused with (semi-?)scams like Mars One.

I love my polyurethane. But they aren't for everyone and they don't last forever. Life is actually shorter than stock,

What? Shorter than stock? That's goofy. That outright shouldn't be happening. Did you forget to grease the bores before installing the inserts?

the ride is much better IMHO. Some people like mush...different bores and strokes for different folks. In a cab, some people would claim the car's ride was 'harsh'.

You can design the bushing for different characteristics. Right now all the offerings are solid bushings designed as ultra-durable replacements for the OE bushing, but if you design the car to use poly bushes from the beginning, you can design as much squish into them as you like.

Bushings are a bitch of a job, even with a hydraulic press. You'll need some steel stock, a band saw and welder to make a custom drift before you are done.

I use a miter saw with a grinding wheel to chop metal stock. It has kind of a wide kerf but it's not really a practical problem. You can use sockets to push poly bushings (they come in a variety of sizes and have a nice rounded edge which won't chew the bushing) and I have a pretty comprehensive set all the way from the itsy bitsy ones up through 3/4" so that provides for installation of most bushings. I also have the HF 4x4 ball joint kit, which can be used in a pinch, if clamped into a vise. My vise is mounted on a pedestal made from a Chevy astro axle shaft and brake drum. And I do have a hydraulic press. The only poly bushes I ever pressed in, though, were big ones from whiteline for the radius rod on the 240SX S13 front suspension. Maybe those were easy.

as far as I understand AI, it's basically plugging the program to a (insanely huge) database about the subject and help him interpolate the input and it's own data. That's computer program getting better, not getting "intelligent". Or is my definition of "AI" that off the mark?

Well it depends on how much you consider "MacGyver" style problem solving to be intelligent. As in I have a task to complete, I have a bunch of random items that can be combined/used in some way to produce a non-obvious result. Computers are great a combinatorics even to the point where they might do something that's original and never been done by a human. A lot of what humans consider creative is putting together known things in unexpected ways, or at least that this particular person has never done before. You might say that the computer is always in the box but we're trying to expanding it while at the same time guiding it so it doesn't get lost in an endless number of possibilities.

Maybe it's easier to explain with a practical example, before you gave the computer a toolbox and taught the computer that the the hammer could hammer, the saw could cut and the screwdriver screw and that was the box. Then we gave it free roam as a few hunks of wood and metal and it got totally lost. Now we give it examples of people hammering and cutting and screwing which guide it, but doesn't bind it. And we find that sometimes it does things in novel ways because nobody told it that it couldn't. The goal is to make "the box" the laws of nature, physics, chemistry, gravity, optics and so on. That we stop defining for the computer what something is and what it can do.

So your argument is that Uber is better than a taxi company that employs serial rapists? Does that also mean that Uber will lose that accolade if they ever employ (sorry, contract) a serial rapist?

Actually, my real argument is that while Uber may be shit, taxis are also often shit. Suggesting that Uber is worse than taxis is dumb. The women I know who have been raped by taxi drivers (two of them, now) use Uber because there is at least some accountability and it's convenient.

Intel appears to edge out in single core performance, but by less than 5-10% depending on processor and we still haven't seen single core performance of Ryzen 5 or 3.

Well so far AMD has intentionally only compared their own 8C chips with Intel's 8C desktop chips that have been clocked very conservatively, all the good chips go to the way more profitable server market and not against the far more price-similar quads. So the quad core i7-7700k is still king of the hill in single threaded with Ryzen 1800X trailing offering about 80% performance (2.02 vs 1.62) in Cinebench single threaded. Of course 8x80% is much more than 4x100% so if your applications use multithreading well Ryzen leaves the 7700k in the dust by a substantial margin. It will be interesting to see if they can bump frequency further on quads, it's a bit the Phenom x6 again with more cores at lower speeds. But a much better attempt at that.

They're not cheap, but they're getting cheaper every year.

I'm just saying driving for Uber under their original/current model is unsustainable. Their drivers are thinking "hey this is better than minimum wage!" but these are people who do not understand capital amortization.

Yeah, by the time you can buy a car with poly bushes (automakers hate them like that one simple trick, because they last forever... no, but really, they pretty much do) it'll probably be self-driving. It'll be the automakers' way of reducing fleet maintenance costs — because they will own the fleets.
