Re: Flat out wrong
Damn it. I like your explanation better. I was taking their word for it re lack of friction. Well done.

From the overhead view, the centre of mass moves toward the 'gate post' when the vertical weights move as far as they can from each other..
So, if the centre of mass is near the post, when the horizontal masses move to the right and then stop, they will have applied a force on the horizontal arm, moving it left in proportion to the relative mass of the horizontal mass...
What I am struggling to convey is an idea of the leverage of the horizontal arm.
Stand on some ice next to a child's roundabou and hold the outside edge of it.t . Have a friend stand near the centre of the roundabout. Now use your arms to slide yourself a quarter of the way round the outside of the roundabout. If this crap analogy works, you will have moved relative to the ground and the roundabout will have moved the opposite way relative to the ground. The amount the roundabout and your friend have rotated will be proportional to the centre of mass of the roundabout and the leverage you get from the radius of the roundabout. Now get your freind to move tt the edge of the roundabout in a straight line so any newtonian opposite force he generates will be directed through the axis of the roundabout and so it will not cause the roundabout to rotate.
Now, if you pull yourself back around that quarter of the roundabout. Because the mass of your friend is now at the edge of the roundabout , you have less leverage to move him, so the roundabout will move less relative to the ground and you will move further relative to the ground.
Get your friend to move back to the centre of the roundabout and you, the roundabout and friend are now all back in your relative positions to each other, but the whole apparatus has eotated from it's initial position relative to the floor.
Sorry if your feet got cold.
Beta testing normally means we're pretty damn close and just ironing out the last few wrinkles?
Observation of the industry leaders indicate.
Alpha :It compiles.
Beta : It compiles and doesn't crash much.
Release : It compiles and doesn't crash much and we put splash screens on it.
Updates: It compiles and doesn't crash much and maybe we tweaked the splash screens and we have increased telemetry.
EOL : The frameworks and libraries have altered enough that it no longer compiles.
Would the Airbus have detected a child on the runway? Or any other obstacle?
Not saying that a pilot would have done any better at landing a plane blind in fog, but I am sure the autopilot was not relying only on its own sensors to land the aircraft and was making a lot of assumptions .
Yeah, I think that the nerds at Tesla chose the name Autopilot because its functions and limitations are very similar to that of an autopilot on an aircraft. They didn't take into account that most of the public imagine that autopilot is a magical intelligent robot that can do anything a human pilot can do
Heck, most of the public probably have no idea how the car they themselves drive every day does anything it does.
Hmmm. Not sure you can resolve every pistcode to a geographic position within 3 feet. Some postcode areas are geographically quite large. the last 3 characters of a postcode give about 7000 permutations, which would be about 7000 square yards or a square of, er, less than a hundred yards on a side.
I can see the postcodes being distributed in some manner and the centres of each postcode being specified to within three feet.
I see they plan to use AI to alter traffic light timing to reduce congestion.
Hahahaha! Silly Chinese! The UK has the only valid plan for reducing congestion, namely an ever-increasing population, closing or narrowing of existing roads, convoluted one-way systems and reducing speed limits.
I am eager to buy a new, fancy mobile phone and will gladly pay £2000 for a really really shiny one.
I am just waiting for the rest of the team to come up with their share of the money. You know, the phone manufacturer who gets all the telemetry, the phone company who snoop everything I do, the websites who track and profile me. Those guys.
Let's face it, they are the ones who benefit from all the clock cycles and bandwidth, so only fair they should contribute.
Sorry, Justthefacts, but it seems to me that you are conflating many job roles.
"we want you to do *less work*, while still achieving the output we care about" sounds like the workers are actually using their knowledge to create products. These people are not permitted to schedule meetings in person or on zoom, also the management above them does not care at all about their "output" .
" the job of your team is coming up with the *next* great product." is not a team that will be creating a product, but is a team which always measured time in meetings as productivity.
" the remote workers have completed the work in pipeline, while shirking the *responsibility* to ensure their company has an ongoing business " seems like you are blaming the pit ponies for the mine's unfavourable contract negotiations with its customers.
If the AV is to outperform a meatbag at high speed driving, it will have to be monitoring events much further in front of it in much more detail than current lidar and camera setups. I have yet to see any AV demonstrating awareness of a vehicle a quarter of a mile away, and with half a dozen vehicles between it and the AV, changing lanes or beginning to brake or both.
You say that driving better than a human will be easily achievable. They were saying that ten years ago and haven't managed it yet.
Adapting the roads and highway code to accomodate self driving cars is just admitting that self driving cars can't do the same job as a human.
The website designers are the ones who put up the dialog which you need to click 'accept' to use the site.They could design the website without tracking cookies, but they choose to indulge in shitty practices.
The EU wonks are just raising awareness of the shitty practices of the website designers.
What is needed is fewer humans. Demolish the low-rise buildings to build high density housing and in a few years you will need to demolish the high density housing to build ultra density housing and then a few years later demolish the ultra density housing to build infinity-plus density housing.
The person had almost completed crossing a three lane road before impact. The car was probably not in sight on the empty road when the person began crossing. The published logs of the car have it first detect the person over five seconds before impact. Plenty of time to either fully stop or change lanes to go behind the person.
I agree that the car was not trying to track possible threats before trying to identify them, I contend that the sensory input has not the resolution nor accuracy to reveal the course and speed of the possible threats and that sufficiently sensitive input would give too much data to process in real time with computational resources that would be practical to fit in a car.
Well put. I would add that the AI seems quite relaxed about vaious objects teleporting into existance near it while it is travelling at 44mph. "Pfft, that thing that I have only just become aware of will probably stay out of my way. Oh, I can't see it any more, maybe the road is haunted or something. Ooh, a different thing has appeared even closer to me, well it might stay where it is or something, oh good it seems to have vanished again so i can just forget about it, hey another thing has appeared even closer to me and even closer to my path, i assume it is nothing to worry about..."
The person was pushing a bicycle across the street, thus the bicycle and its shiny hard metal surfaces was broadside on to the car's sensors, giving the best possible chance for detection.
A cynic might think that the problem is data processing. If you give the car enough sensors to give a detailed and accurate picture of its environment, the computers needed to interpret all that information in real time won't fit in a car (or maybe cannot be built).
"building roads tends not to decrease traffic congestion. All it does is increase traffic"
I think it more a case of building roads at a slower rate than the population increases tends not to decrease traffic congestion. All it does is increase traffic .
Inrcementally increasing bandwidth on a saturated channel will not eliminate contentiion when the demand is also inrcementing.
