As you listed it's in #5 worst in 27 in the EU. How it ends up being the darling "sucess" case from the numbers beats me.

There are not that many countries that are worse than Sweden in the pandemic numbers. And Sweden's neighbors have all done much better. Economically everyone in the EU is similar. There's still quite a bit to study but this fixa

Teslas work exactly like this without Autopilot. It's one of the assistance features, just like warning if someone stops in front of you and you don't seem to be reacting. These features also get better as Autopilot gets improved

Per-distance statistics may stretch the risk perception as people use planes for different trips than cars. But per journey statistics seems a much bigger error in the other direction. Fatalities with airliners are pretty close to 0 per yea

Something here is unrealistic, that's the point. I'm not so sure it's the reliability threshold for self-driving cars though. I'm more amazed at our continuing acceptance of the risks in driving. Having two pilots, air t

The Wikipedia article is just for the fatality statistics. The expectation of airliner reliability for self-driving cars is what I get from the discussions around this. Here on HN and in other places. Maybe it will be lower and the uncanny

by pedrocr 6y ago
That rate is on the order of 1000x worse than airliners which was the comparison as that's the level of reliability people are expecting from self-driving cars. A self-driving car that's 100x worse than the airliner standard would

I agree completely. My take from the situation is much more that we are far far too lenient with our standards for cars, roads, and particularly drivers. We've set the bar so low that the technology has a good chance of clearing it soo

I can see it being possible to "average out" the mortality of self-driving cars when you consider how high road mortality is. But they won't be the same deaths, some would be things a human driver would avoid. We generally de

Yes, that's the suggested fix. My question is if treating this like a CPU branch predictor and keeping some state that needs to be updated is too expensive or not. The packet pipeline is very performance sensitive.

So the kernel is using a static decision that's really bad sometimes? Would it be too expensive to treat this like a branch predictor and keep some state to have the kernel enable/disable the delayed ACK dynamically depending on h

They've already announced it. You're assuming the retail availability will take a while?

What would be the 2 good die release? They've already announced the line-topping AM4 part that uses all the cores from the two dies. Isn't the next step up a four die part in a Threadripper packaging on a different socket with som

Linus Tech Tips did it with an aquarium cooler: https://www.youtube.com/watch?v=HMtvEbD2MQo It looks like quite a straightforward setup actually. But a custom water cooling loop is almost surely a better solution.

The IPC increase seems to be coming from the microarchitecture, not the process. The Anandtech article includes a breakdown: https://images.anandtech.com/doci/16148/1%20Slide%206_575px.... +2.7% Cache Prefet

Amazon already operates EU-wide both on their Logistics (there's only one shared by all) and their frontends (all of them work for all countries and share the same code and login). They've already achieved a superset of what amazo

Note that most of the energy in gasoline gets wasted as heat in a car, only a part gets used in winter to heat the cabin. So there's a factor of ~3 that you get back in that comparison. So the more comparable number is more like 3-4%.

It's one of the ways Amazon screwed up in the EU, probably the main one. They don't have a EU-wide site but do ship EU-wide. So you end up shopping across 5+ different Amazon stores, with slightly different prices and offers, all

I know that motivation but I'm more curious about the hardware architecture angle. Integrating the memory controller in the CPU was supposedly a big gain at the time. Now it's in a different chip and multi-socket motherboards alre

So AMD is back to having a northbridge again but it's on the same package instead of the motherboard for latency reasons? Or could we actually get away with a northbridge on the motherboard again?

by pedrocr 6y ago
ECC on AMD seems quite hard in practice even though the CPU support isn't artificially limited like with Intel. Making sure the motherboard supports it is hard and then the RAM options are extremely limited and generally quite slow and
