Singapore appears to have killed more than just half my skin

Heh, this holiday has so far cost me £2998.65, excluding cash

Probably about £4000 if you include cash and incidentals, like passport, and those speakers I bought at Challenger.

So right on track for double my intended budget. Just like every time -_-

@HackToHell hah! AMD said they are already on 14nm FinFET

also, "similar to 6 Titan X"... that's gonna get expensive fast

That sounds dangerous.

I want my self-driving car to be predictable, tyvm

@Bob luddite

qasdfdsaq

@PatoSáinz Not really. It's only 6x the Titan X's GFLOPs rating because the Titan X's GFLOPs rating is artificially crippled

A £50, 6 year old GPU has more GFLOPs than a Titan X.

Bob

@PatoSáinz oh, sure. break out the meaningless insults.

maybe an opportunity for AMD, with their faster FP

HackToHell

@Bob Elon Musk in a blog mentioned that the system was 99% accurate but a car not detected at 70mph is very bad. That's why the cars need more computing power I suppose.

qasdfdsaq

Also, typical nVidia number bending... where exactly did they get the fact that 8 TFLOPS is similar to 6x 6.6 TFLOPs?

@Bob Self driving cars are already too predictable

@HackToHell it's ISM band

qasdfdsaq

> It doesn't matter how well we program a car's maps and sensors -- it also needs to know how to deal with changes on the fly, like when a child jumps out on the road.

Err, Google's self driving car already handles all obstacles perfectly well. Stop.

ChatBot John Cavil

HAMMERTIME!

Bob

s/child/object/

There's only so many actions you can take anyway.

qasdfdsaq

@Bob And computers are already far better at choosing the best one than humans are.

HackToHell

5:17 PM

@PatoSáinz and that band is used for GSM-900

@qasdfdsaq Still not good enough

Bob

Machine learning for decision making in a car seems fairly pointless at best, outright dangerous at worst.

qasdfdsaq

@HackToHell Far better than good enough

Within a few milliseconds it can detect the obstacle, determine its size and direction, as well as calculate the car's speed, heading, traction, and stopping distance, along with swerving distance and determine the optimal course of action, based on the location and velocity of all objects around it.

Bob

Machine learning necessitates a fair bit of trial-and-error... what, you're going to crash into 10 trees before you figure out that, maybe, you shouldn't do that?

qasdfdsaq

A human takes over 200ms to just notice the obstacle in the first place.

@Bob LOL

HackToHell

@Bob It's all deep learning and neural networks these days

Bob

5:18 PM

It makes even less sense on a per-car basis. But spread across a connected network might work better.

qasdfdsaq

@HackToHell It's a load of shit to sell overpriced hardware.

Bob

If you can learn from accidents of other vehicles.

qasdfdsaq

So far self-driving cars have not been responsible for any accidents...

HackToHell

@qasdfdsaq Uh, neural networks are far better at object recognition

And they do use a lot of computational power

Bob

@HackToHell What kind of object recognition do you really need for a self-driving car, though?

qasdfdsaq

5:20 PM

@HackToHell A car couldn't give a damn about advanced object recognition.

Bob

You need to know what other vehicles are. You need to know obstacles. You need to know speeds.

qasdfdsaq

It can recognize every kind of object it needs to already.

Bob

You don't need to know if it's cat, dog or child.

qasdfdsaq

@Bob I suspect the deep-learning aspect and adaptability is not really in order to avoid accidents

Bob

It doesn't matter if it's a bed or a cardboard box.

You just need to know (a) it's in front of you and (b) you don't want to hit it. And you can stop or move around it. Not much else to do.

qasdfdsaq

5:20 PM

More to cope with unusual road conditions - unpaved roads, boarding a ferry, diversions, etc.

HackToHell

The entire terrain is fed onto the neural network with variables and the network itself segregates what causes the actions

qasdfdsaq

Crossing a field... water on the road, etc.

Bob

@qasdfdsaq Then we get back to the tradeoff between trial-and-error vs a human programming the best response in.

qasdfdsaq

@HackToHell You really should watch some demo videos about how self-driving cars actually work.

Bob

What does it take to figure out how to board a ferry? How many times are you going to drive into the water?

qasdfdsaq

5:22 PM

@Bob That's the thing - machine learning removes the need for humans to program the best response in. The whole point is to figure out the correct course of action the first time

Simple trial and error... isn't "deep learning", it's dumb learning.

Bob

@qasdfdsaq But you need prior experience of some sort.

Whether that's someone programming in "water = bad" or it somehow learning that beforehand.

qasdfdsaq

We don't need 8 teraflops and deep-learning AI to figure out driving into a tree is bad after several attempts.

Or water.

Or anything else you shouldn't drive into

Bob

Without experience, whether by programmed rule or by experimental results, you can't judge any choice as better than others.

Obviously not having those would be absurd.

So the real question is how much the adaptability can really help above the core rules.

HackToHell

@qasdfdsaq that's not machine learning

-.-

qasdfdsaq

@HackToHell No shit, that's what I just said

Anyway, off to bed. I've got 27 hours of travelling to do tomorrow.

Bob

5:26 PM

Maybe you can improve fuel efficiency by moving slightly differently in different conditions.

Small things like that.

Safety decisions are rare (and varying) enough that it wouldn't be as much use.

HackToHell

spectrum.ieee.org/cars-that-think/transportation/self-driving/…

Bob

@qasdfdsaq 'night. Have fun on the flight(s) :P

Oh, don't forget to reclaim your headphones?

qasdfdsaq

@Bob Safety decisions are so deceptively simple I could do it with a bash script.

@Bob Heh, yeah. Flying from tiny back-end of nowhere town in Thailand to tiny back-end of nowhere town in Aberdeen is going to require four changes...

Also I got a (seemingly half broken) spare set of headphones off a mate here, though now that you reminded me I should check if Singapore airport has my glasses. If not, they're probably not worth reclaiming from Sydney.

Bob

@qasdfdsaq Until someone installs zsh and your script errors out :D

@qasdfdsaq Do you swap planes on that flight? Or did the people stopping in Singapore just get off?

Hm. Probably the former for such a long-distance flight.

qasdfdsaq

Just don't start programming computers to make decisions based on moral grounds or the fat man/trolley problem.

@Bob Through flight on the same plane.

Bob

5:32 PM

@qasdfdsaq Then is it everyone off => rest, stretch legs => back on, or do the continuing passengers stay on the plane?

You can probably tell I've been on more long-distance bus rides than planes :P

Hm. Thought you were in a larger city in Thailand.

qasdfdsaq

@Bob I hear it's everyone off => back on, but I've never had to do it myself. In the old days people didn't have to get off, now they do (some weird regulations)

Bob

@qasdfdsaq One thing that's annoyed me whenever someone talks about AI utopias and morals. They never seem to consider that the AI will largely get its morals from either the programmer or whatever material it learns from. And if that's the internet then god help us all.

Hmm, seems even the 777-300ER can't fly London to Sydney non-stop

ChatBot John Cavil

HAMMERTIME!

Bob

Cavil just loves you :P

@qasdfdsaq I'd be more surprised if it could.

qasdfdsaq

5:37 PM

@Bob Well the 777-200LR could... almost

Bob

o.O

That's a damn long way.

@qasdfdsaq Is that an almost with or without safety margins?

qasdfdsaq

I don't know if the range ratings usually include safety margins or not

But I'm pretty sure I recently read that there was at least one airliner, either recently released or in development to be released in the near future that could do the trip non-stop

ChatBot John Cavil

HAMMERTIME!

Bob

@qasdfdsaq Hm. Standard turbofan engine?

I remember seeing a lot about ramjets, etc., no close plans.

qasdfdsaq

I'm guessing the range ratings do include safety margins, as the A380 is rated for 8500 nautical miles, and is in actual commercial service on a route of 8581+ miles from Dallas to Sydney

Bob

5:44 PM

Ah.

Next step: check what the safety margins are :P

qasdfdsaq

Oh wait, nautical miles vs. non-nautical miles

My bad.

Rated at 15,700km, route length is 13,800km+

A350-900ULR will be rated for 16,112km though, just barely under the 16,884km distance from London to Sydney.

Huh weird

Boeing 777

The Boeing 777 is a family of long-range wide-body twin-engine jet airliners developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and has a typical seating capacity for 314 to 451 passengers, with a range of 5,235 to 9,500 nautical miles (9,695 to 17,594 km). Commonly referred to as the "Triple Seven", its distinguishing features include the largest-diameter turbofan engines of any aircraft, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone. Developed in consultation with eight major airlines, the 777...

Bob

@qasdfdsaq So they could probably stretch it.

qasdfdsaq

^^ This claims that at least one variant of the triple-7 is rated for 17,594km, but doesn't say which one, and never mentions that distance anywhere else on the page.

Ah, 777-200LR, 17,600 km.

Could most certainly do London to Sydney non-stop, as that's the distance achievable with maximum payload.

Bob

@qasdfdsaq 777-200LR

I'm too slow :P

qasdfdsaq

Ah, 777-8(X):

> The 777-8's length is between the 777-200ER and 777-300ER with seating for about 350 passengers in a three-class configuration and has a range of 9,300 nmi (17,200 km) or more.

Bob

5:50 PM

Huh. They gave up on the triple-digit numbers? :P

qasdfdsaq

Anyway, enough aircraft talk. I'm off to bed.

Really this time.

Bob

It's unlikely. You may be able to take a Verizon Wireless device to another carrier and get a new SIM card with that carrier. However, you would have to check compatibility with the carrier first."

So Verizon defines "Bring your own" as "Bring your own as long as it's a Verizon device" :/
