Yah, but automakers are very cost-sensitive, and flash memory/NVM is one of the easiest places to penny-pinch. I get crap about 2kB payloads.

Car companies, both electric and non-electric, frequently advertise rated horsepower of their vehicles, even non-performance vehicles. In the US, horsepower is one of the key metrics for a vehicle overall.

As somebody currently working at an automaker on software systems, the amazing thing to me is that a mess up of this level doesn’t happen weekly. It’s rough out here.

Sure, but that’s a lot different from not being able to see them at all.

Do you have a source for this? There’s a gap between semi wheels, sure, but the deck height of a semi trailer in North America is about 48”. If automotive radars weren’t able to detect objects above this height, they would miss a lot of obs

What?? Yes, there absolutely were people who were run out of town for being gay. There was indeed rampant homophobia. What world were you living in?

I work in the space and I have not been impressed by the quality of Thatcham’s requirements once you get past the physical domain (door handle pull force, steering column locks, etc).

Yep - and not just between automakers, the security model varies wildly between different electrical architectures from the same manufacturer. Like any industry, there are hard problems, some of which are technically difficult, and some of

I work at Ford on vehicle access and security and I’m quite familiar with CAN security challenges and solutions. (Of course, I don’t speak for my employer here.) Without speaking specifically to Ford’s plans, authenticated CAN communication

This comment touched on a lot of the wrestling that I’ve been doing for the past couple of years with my relationships to productivity, intentionality, and fulfillment. It’s a really useful perspective and validated some of my feelings. Tha

That’s exactly what they’ve been adding, actually. You can also set a schedule for which mode is active or trigger them with automations.

They control the heat input, too. Software fixes: * limit max current (dumbest) * limit max current based on moving average of current over last N seconds * limit max current based on experimentally validated thermal model of contactors (cl

Pretty difficult to get a “wallpaper” fix through the processes at an OEM like Ford. (I work there but I’m not involved in this issue.) Automakers have lots of experience making painful and expensive fixes to resolve recall issues, and NHTS

I live in a major US city and my power goes out at least once every couple of months, sometimes for hours at a time. I have installed several UPSes on important electrical things (servers, routers, modem) to avoid the hassles that come with

I live in Detroit, a couple of miles north of downtown. I wouldn’t think twice about wandering around downtown, anywhere downtown, at any hour of the day or night. It’s just not dangerous at all. There are certainly neighborhoods where I wo

Dude, your argument is “yeah, but what if the Aboriginal Australians actually deserved to be ground into dust”?? The hell?

Sure, maybe there’s less need for charge balancing in a smartphone battery, but the rest of the constraints still apply - fast charging is hard!

by aaronbeekay 5y ago
Yes, it’s true that you can implement a pretty simple generic lithium-ion cell charging algorithm that will get the job done for most cells. But that’s not a “modern battery pack”. If you’re trying to eke hundreds or thousands of charge cy

Hasn’t somebody who is born free and then later purchased and sold as a slave been kidnapped at some point, even if not by the person who is selling them at the international border? I’m not well versed in the history of slave trade, but I

Firstly, regardless of where a person ends up, if they get there by having several generations of their family kidnapped, enslaved, and systematically mistreated, I think it counts as “a hell of a hand”. Secondly, it sounds like your thinki

I work at a major American automotive OEM on entry and starting systems. Yes, many passive-entry/passive-start systems (like those that use door handle sensors to trigger an unlock) are vulnerable to relay attacks. Relay attacks are se

Agree with this broadly, but also CAFE (corporate average fuel economy) standards in the US mean that it likely was not possible for Ford to eliminate sedans before CUV fuel economy increased to a comparable point. (I work at Ford, but in a

I work in product development at a major global automaker. I have never heard somebody call a BEV program “simple”, and if somebody is trying to sabotage BEV projects, they’re doing a very, very bad job of it.

Firstly, I think there’s a pretty clear difference between enslavement, which is a practice that intentionally deprives human beings of their rights, often violently and often en masse, and beef, coffee, and chocolate, which are food produc

The automotive industry has standards that govern the systematic development of safety-critical systems (hardware and software). The most significant is probably ISO 26262, which defines an “Automotive Safety Integrity Level” and methods fo

Hmm, not us! We were there in '13 and '14, and our bike was built on a CBR1000RR chassis. I can't remember who had a yellow bike, although it sounds familiar... it may have been a bit before my time if they were talking about

I work on a team that designed two electric motorcycles for the IOM TT Zero. Yes, it's a very different game from the gas races. Aero and energy storage on board are the primary concerns - the top team for the past several years has be
