Which is why Googles system (lowering the parcel on a rope, the drone never comes even near ground) is superior to Amazons (land-and-release) system.

In general, though, I do agree with you.

The main problem with traffic is not delivery vehicles, but single-person private cars. For them, more efficient transport options (car sharing, public transport, bikes) exist. For delivery, the truck is often the most efficient solution already.

You never bought the airspace above your house.

You are wrong about that. I cannot legally build my house right over your house, even if it never touches the ground that you bought.

Clearly, airlines are flying above without considering property rights below, so somewhere "your" airspace ends, but just because it's in the air doesn't mean it doesn't touch property rights.

The number of autonomous vehicles on the road is so absurdly low that the stats are irrelevant.

Sorry, that makes no sense whatsoever. Statistics take the number of vehicles and driven kilometers, etc. into account and they are still clear as day. If anything with more autonomous vehicles, the existing ones will become more safe, because there is less unpredictability.

Recall that Airbus' fly-by-wire didn't have the greatest introduction to the world, considering they crashed a jumbo at the airshow meant to introduce the world to it.

A spectacular failure, for sure, but still FBW has become the standard today. Yes overrides exist in most airplanes, just like autonomous cars have steering wheels and pedals. I fail to see your point, especially considering that AF 269 was not the "introduction to the world" of FBW, there had been numerous other aircraft with it before. It was just the first time it was used in a series civilian jet.

At least in the near-term.

I don't expect them to become the majority of cars within five years or anything. But continued development work is exactly how all the problems will be solved. Driving, on the other hand, is not really all that difficult when you recall how many idiots manage to do it. It's just that our roads right now are designed for human drivers, from signals to line markings to unwritten rules.

For whatever reason, it isn't something there's much interest in, but it does exist. I am aware of three options:

1) The HeaDSPeaker. The cheapest option. A little device from a not very well known company called VLSI Solutions. It handles the head tracking and HRTF, you provide the headphones. Runs about 340 Euro ($450). It can take input either as a Dolby Digital stream, or directly as USB from the computer.

2) The Beyerdynamic Headzone. This is an all-in-one solution from Beyerdynamic. Has a decoder, HRTF calculations, headphone amp, head tracking, and a pair of DT 880s. Costs about $1700. Requires DTS or DD input for multi-channel input.

3) Then the grand champion, the Smyth Research Realiser A8. This thing takes measurements of your headphones, ears, speakers, and room and so accurately recreates the sound it is more or less impossible to tell it apart. The unit handles measurement, decoding, HRTF, head tracking and so on. However it costs $2900 for the unit alone, $3700 with the Stax headphones and amp they recommend for it. Oh and you need a good surround system to measure, so you either need to own one or book time on one. Needs either multi-channel analogue or HDMI input.

So it is out there... but you pay a ton for it. That's all I know of at the moment, it is a topic I keep track of because I have a lot of interest in it.

Comment That's a pretty silly statement (Score 1) 181

In computer technology, there is ALWAYS something new next year. Yes, there'll be a 14nm shrink next year (or maybe later this year)... but then just a year away will be a technology update, a new core design that is more capable, and of course they'll have more experience on the 14nm process and it'll be better... however only like a year after that 10nm will be online and that'll be more efficient.

And so on and so forth.

With computers, you buy what you need when you need it. Playing the "Oh something better is coming," game is stupid because it is always happening, generally very quickly.

So if you want a 6 or 8 core system, this is what to buy (it's cheaper than their Xeon setups). Will there be a better ones later? For sure. However sitting in neutral waiting for "the next big thing" is silly. Get a system, keep it as long as it is useful, get a new one when you need a new one.

Also hating on this for being enthusiast is silly. Ya it is expensive. So don't get it if you don't need it. However for what it does, it isn't bad. Maybe you need that kind of power. Maybe you need more. Not long ago we had a faculty member purchase workstation with 2x 12 core CPUs. These things cost about $2600 PER CPU, never mind the other hardware to support it. System was over $10,000. However, for the simulations he was doing, it was worth it. I'd never buy that for home, my workloads are much lighter, but I'm not going to hate on him needing it.

Same shit here. Do most users need this? No. Heck most users don't need a quad core. But there are uses for it.

I have never seen RAM as cheap as it is now. When you can buy a 16GB ECC DIMM for less than $200, it is rather wonderful. Our researchers that use big amounts of memory are extremely happy with how much memory they can stuff in desktops and servers for a reasonably price.

Now I'll admit, I don't have a chart of RAM prices, so I suppose I could be wrong, but then I've worked in IT for the last, oh, 20ish years on a continuous basis and spec'ing and buying hardware is a fairly common part of my job.

So please, show me some evidence from two years ago when RAM was half its current price. Right now I see a 16GB 1600MHz 2R ECC DIMM as running about $170, and a 4x4GB 1600MHz unbuffered set running about $150. So please show me some proof that two years ago I could get those for about $70-90 each.

Comment How is that surprising? (Score 1) 181

Have you looked at RAM prices? 32GB of DDR3 RAM is about $300-400 for a 4x8GB set, depending on speed and company. So $600-800 for 64GB. Ok well how about server memory, since you can get servers with 6TB of RAM if you like (really, check HP or Dell). For a 16GB DIMM, which is the largest you can get before the price per GB skyrockets, it is about $160-200. fo $640-800 for 64GB.

So hmmm, looks like DDR4 is right in what other ram costs, plus a bit of a premium since it is brand new tech. What a shock! Who would have every thought it would cost about what RAM costs!

Get off it. Also it is stupid to act like everyone would need to buy the max amount of RAM. That the system SUPPORTS 64GB doesn't mean you have to BUY 64GB. It means that if you need that much, you can have it. If you need less, get less. Most desktops sold today support 32GB in the form of 4 sticks of 8GB DDR3 RAM. Most systems ship with only 4-8GB of RAM, in 1 or 2 sticks. There is nothing stopping you from using less.

You see this even more on the server market. We like Dell R720XDs at work. They support 768GB of RAM. However 0 out of 5 that we have purchased have that much RAM. It is exceedingly expensive, since it needs 32GB DIMMS. However it also means that getting 384GB is much cheaper, since it has the ability to do that on 16GB DIMMS. That said, we have only one system that needs that much RAM. The rest? Between 128-256GB. The rest of the slots sit empty, ready to be filled as our needs grow. Two of the 128GB servers will probably be getting more memory soon.

So seriously, get off it. DDR4 really isn't much more expensive than DDR3, much less than I thought, and memory is cheaper than ever. All these boards mean is if you need a lot of RAM, you can have it.

Comment Because people can twist religion as they like (Score 4, Insightful) 369

The thing is, religious texts say a lot of shit, particularly the major religions which often have a whole lot of text including not just their "official" book but all kinds of other documents that have some measure of authority in their belief system for various reasons. Also because the documents are old, and composed of various collected stories of various authorships, there are generally plenty of contradictions, things that have been shown to be untrue, and so on.

So what really happens is people choose to believe the parts they like, and ignore or reinterpret the rest. They follow the parts they wish and find justifications for not following the others. This happens all the time in all religions. Generally, religious ideology is an excuse, a justification, for a behaviour, not the case. People don't read a holy text and say "Oh, well I have to follow this to the letter!" Rather they have something they want to do and they find a way to make their belief system justify it.

You can see it with things like the "prosperity gospel" Christians and so on. Any even somewhat literal reading of Jesus's teachings shows the guy was the ultimate hippy. All about helping the poor, against material wealth, etc, etc. However, they find a way to justify their views in the bible.

Or the crazy things Orthodox Jews go through to supposedly obey arbitrary restrictions in the torah, while then skirting around them. Like they believe that the prohibition on making fire on the sabbath applies to electricity. However then there are things like ovens with timers greater than 24 hours, so you can have it come on automatically on the sabbath and that's ok. Oh Shabbos Goys, non-Jewish individuals you can hire to do things for you that you are not allowed to do on the sabbath.

Same shit with any of the variants of Islam. What the Koran says isn't really relevant. They'll find a way to make it justify what they want to believe. They can find a way to twist it to allow things that are specifically forbidden, or to ignore things that are required, or whatever.

Comment Something many forget (Score 1) 848

Is that when you buy US Treasuries, you don't actually get anything. They don't send you a magic stone with powers to call in a debt. What happens is there's an entry made in a computer database, a computer that is in the US.

What this means is that the US ultimately has control over the repayment. Now both legally and practically the US is obligated to repay their securities per the agreed upon terms. However, that goes out the window in the case of a war. US law allows the freezing/seizing of assets, and other countries would have no problem with the idea.

So a situation could arise where the US simply declares China's holdings to be invalid and null. So long as the other bond holders are ok with this, and the (US) courts see it as legal, then China suddenly loses over a trillion dollars in investments. They can't just run off and sell them or something, they have nothing to sell. This would tank the renminbi and really screw China over. It actually could have a positive impact on the US, particularly if the other bond holders saw this as a positive (because the US owes less) and trusted that it wouldn't happen to them.

A country selling treasury notes isn't like taking out a loan with a loan shark. It works really different. US securities are:

1) Denominated in US dollars, and thus only worth something if the dollar is.

2) Payable on defined schedules, with no ability to "call in" the loan early.

3) Nothing more than promises to pay from the US government, and thus only valid if the government decides they will pay.

Putin is pushing, because the West is pulling back. Some blame can be laid at Obama's feet, though I don't think anyone would want a President who went around making threats of open warfare. A lot of blame can be laid at the EU's feet, for inspiring the revolution, and then getting weak-kneed when the Russians became belligerent.

One thing is awfully clear. If you're an Eastern European nation with even a handful of ethnic Russians in your territory, you have a serious problem.

I don't trust software to take control away from the driver.

While I completely agree, subjectively, I also understand enough psychology and statistics to know that a) the feeling of control is mostly emotional, not rational. It's why your mother in the passenger seat is scared in situations where you as the driver are completely cool - you are in control, she is not. That she's more easily agitated only makes it more visible. It's a well-documented fact that experiencing the same situation once in control, or even just seemingly in control, and once not in control is experienced very differently.

Statistics, on the other hand, show that even at this early stage, autonomous vehicles have a better-than-average track record. So while you may feel less safe, the numbers say that you are actually more safe.

etc that won't be participating in this V2V conversation.

Which is why autonomous or semi-autonomous (assisted driving) vehicles do not rely on one input source alone. V2V is not intended to replace all the sensors and stuff, it's one more input source.

Great, but that doesn't mean you're now free to be inattentive! If anything, cars should be less safe and speed limits higher to force people to pay attention, or else.

Humans are really, really bad at paying attention to monotonous tasks for extended periods of time. The sooner our cars drive themselves completely, the better.
