There is a place - somewhere in Ukraine, I believe - wich was visited every summer during the previous 'ice age' (yes, there was still summer and winter and the low parts, depending on latitude melted and had grass and trees)
That place was basically occupied _every_ summer for over 60,000 years. It was a hunting place where they hunted horses (very small, as big as a big dog) and left a pile of horse bones and others, over that extreme long period.
The people lived in winter some 5 km more south, and walked there in spring and reached it in summer, spending about 3 month there.
It is supposed that the "red hair" genes are Neanderthal genomes, and probably many others too. The interesting question is, if Asian or African people have also Neanderthal genes.
I'm sailing about once a year, most of the time we don't spent the night at sea, but even inside of a small towns harbour at the mediterranean sea, you see stars over stars over stars. The term Milkyway suddenly makes sense...
Venus is one of the brightest objects on the sky, unless it is clouded, you should always be able to see it. (I mean when it is possible to see it, ofc.) However if you have a bright light source in front of it, then you can't (you could try to shadow it, though)
As long as we have recorded history, that means written, and still available to read: mankind was interested in stars. Basically everything we have in our days time in measuring of time and geometry comes from observing the stars and the sun. So yes: I'm pretty confident that early humans at that time cared about the sky, noticed the star, and probably made cave drawings of it. But: we likely never find any evidence for that.
Mankind at that time was primitive in tools, for some reason finding stone that bleed metal and makes them wonder what to do with it, seems to be a rare event. However they where a smart as we are, our brains are still the same like some 400,000 years ago.
Most comets are part of the solar system in the sense that they simply orbit the sun, the rest are in the Kuiper belt. If there is a Oort cloud (we actually don't know that) objects from there only get kicked closer to sun when their orbits are changed by a passing big object. Claiming that objects that are a light year away belong to our solar system is rather esoteric, don't you think so? The solar system is traveling with about 83000 km/h or 52000mph through the galaxy. If the Oort cloud would be similar fast going the same course, I would agree it belongs to the solar system. If the objects have their own idea where they move to, then they don't belong to the solar system.
most of which were not related to anti-government expressions but rather for "speech" that was offensive to some portion of the community. And that is not protected by the first amendment, that was one of my points.
Sorry, your interpretation of the "Bill of Rights" makes no sense. Obviously the whole bill only covers people. Does not matter if they are explicitly mentioned or not.
For funk sake. And no disrespect intended. That driver is a convicted robber, a simple $9 per hour "emergency driver".
In Germany such a position would be hold by a $100,000 per year Electric Engineer or Software Engineer or Physicist. Actually you usually have 3 or 4 of them in a test car!!!
No one would put a former unemployed into a autonomous test driving car and expect him "not to text" and "pay attention".
That only shows how fucked up your "capitalism" idea is to take the cheapest bloke you can find to do a job. You have an "emergency driver" earning about $1500 a month in a car worth a million... how retarded is that?
And you now try to turn it down to "normal"... no one can do that...
It is the same principle as in "bearing", but you use the intersecting spheres they "produce". And obviously instead of aiming towards the satellite as in "bearing" the satellite tells you where it is, so: it is exactly the same principle as "bearing".
Corporations have no free speech "rights", check your constitution. And then again "free speech" is not what you think it is. It only means the government can not harass/punish/imprison you for what you said AGAINST that government. You still are not free to insult other citizens or call for violence, your legislation who has to file a case and who can prosecute it, may vary.
The only thing that is truee that you need more hardware to track up to the maximum of sattelites over the horizon. The rest is simply false, sorry. Already the 'precission' claim is false. If you track more then the minimum required satellites the GPS, choses the ones with the clearest signal, or those with clear enouh signal, that have the biggest angle towards each other in the sky. And that is the only reason why you want more than 3. Having more than 3 does not add the singlest bit of precission. How would even the math work, to jump from 3 sattelites to 4?
You can easy check that on paper in 2D.
Make some crosses somewhere as refernce points assuming you are in a boat somewhere in the center. Use two of the crosses and draw lines to the center that intersect. "You are somewhere there". Call this point A. Now we know we have an inaccuracy of lets say +/- 5degrees. Draw for each line two dotted lines in -/+ 5 degrees angle. Where your boat is, you have now an irregular quad-angle. It is somewhat safe to assume your boat is inside there. Now look how big that area is in comparision to the original intersection of the first two bearings.
Anyway: now take a third X to find a bearing, keep in mind, it won't intersect with the forst two... in other words the straight line bearings will form a tri-angle where they meet. Now we could assume that the ship is somewhere inside of that triangle. But look at point A. carefully.
Again add two dotted lines for a +/-5degree error margin. So, why would you conclude now, your boat is inside of the triangle, when your new error margins for the last bearing, clearly indicate it could be outside 'behind point A' somewhere?
It is just psychology that you believe you are inside of the triangle... the third bearing did not add any more accuracy. It only showed you how improbal your first two bearings were.
Now do it with an board radar to two solid objects and you know your position up to a few cms.. no need to use a third bearing.
Same with GPS. You need as many bearings as you have dimensions, and thats it.
More sattelites only give you more options to pick 3 which will give you a perfect 'bearing'. (in 2D a perfect environment for bearings would be two easy to pinpoint objeccts that have roughly a 90degrees angle to each other, two objects that are close to 180 degrees to eacch other are obviously a poor choice)
A crypto currency, does not need to be mined, it simply can be minted, so no particular cost in energy. Most actual cryptocurrencies, most notable bitcoin, are not anonymous at all. A government e.g. could even go so far to actually back the currency... which would probably not make much sense, because of the involved costs.
Well, there is lots of literature about usage of neuronal networks in self driving cars. But I assumed we agreed 15 - 20 years ago, that they are not suitable.
The self driving cars, I was invloved with run on 3 or 4 ARMs with standard algorithms in C++, I doubt in Europe anyone uses ANNs for self driving... what would be the point?
ANNs are extremely good for classifications of input, and generating a suitable output, like in Go or Chess. But a decission to switch lane is much more complex (in relation to a simple classification of an image) and requires much more output then simply a single decission which piece to move to where.
If Uber still thinks they can use ANNs (google prooved 15 years ago, it makes no sense) then they are far astray from getting a self driving car in the near future.
Why should the feet of the drivers not be on the pedals? Well, mine are always. So if I have to brake, I release the throttle and put it on the brake. My other foot usually is always on the clutch... on the other hand, I have no automatic speed holding, so.k have to be on the pedals.
The onservation about Olympics is actually slightly more complicated. While they have a true reaction time around 0.1sec, some years ago it was decided that reacting so fast is cheating. So they have actually to wait a very brief moment before starting.
Regarding driving, if you look ahead and pay attention, there should not be many surprises anyway, as you usually can slow down long ahead of a problem.
LIDAR systems are basicaly infra red laser scanners. They should be immune to most bad weather situations, and most importantly: a huge red flashlight should be in the cockpit when the LIDAR realizes it only scans bogus.
Planes would not fly if a pilot had a 3 seconds reaction time. Nor would you drive your car. It is a no brainer that reaction times are not that long.
And as I mentioned before, my reaction time is close to optimum, which is 0..1 seoncs. It is hard to believe that the average person would be 35times slower than me.
Actually I do martial arts, look at boxing, how should that work if people need 3 seconds to decide if they take the arm up, or move to the left or to the right or counter with a hook etc. ?
With 3 seconds reaction time you could not evven play baseball or soccer... that should be common sense:)
I agree with most. However regarding Java: if you want your own memory management, you can 'disable the GC' in the sense that it only gets triggered when you are really out of memory and manage your 'released' objects in free lists for later reallocation. Most embedded JVMs make hard guaranties how much time they spent allocating an object, and use that time for a mini GC period. There are commercial JVMs that have similar options, or run on custom hardware which is much faster than an x86 anyway.
The idea that you can assign an int to a boolean is deliberatly not in Java (and its sister languages), so bugs like this can not happen: if (a=b)// should be ==....
Of course a matter of taste, I like it though.
Maven sucks, that is true. Some idiots who only had the basic grasp about how to write a build system/build tool invented it and called it maven. Maven as in Magician. Probably the name fits... magically it somehow works, and no one knows why or how:) And they settled on XML as description language... but still don't check if the XML is valid... Gradle however I like, it is basically a fancy make file.
Java does not require one class per source file. It only requires one public class per source file, and of course you can use nested top level classes (via static).
Yes, being forced to unsigned ints is/was extremely limitating. I once wrote a kind of SWEET16 emulator (same idea, but different hex codes for the instructions), it was a pain in the ass...
I mean in C/C++ it would have been a quick hack, so it took me 4 days (but it includes a goovy DSL for the mnemonics to have a kind of real assembler)
There is not enough gold on the world (including the not mined one) to "back" the world trade. World GDP:$107.5 trillion Total amount of gold: $8.1 trillion
Bitcoin is designed to be deflationess and not inflationess.
