extropy··on Tesla remotely converts battery pack, cutting 1/3 of range
Offering a choice is tricky here. Since failures are significantly affected by the software ability to properly manage the device (and needs to be updated periodically to keep that up to date).

So yeah you can choose to keep the old version and loose warranty, cheers!

Im not sure what the legal side of warranty conditions is. But outdated software is potentially a very real cost to the manufacturer in therms of extra warranty work.

extropy··on BMW introduces new heated seat subscription in UK
I think there is none, except you loose some warranty and access to BMW digital services, like updates.

As I see this, you are buying two pieces of stuff - the physical car and a software subscription service. Maybe we need to split the two out? Like on PCs you can install any OS you want.

extropy··on Former U.S. congressman, operative pleads guilty to election fraud charges
The machine prints a paper ballot that is considered the actual vote. Any electronic copy is just a counting optimization.

extropy··on In Defense of OpenStreetMap's Data Model
Only for the ones trying to write it down as 32 bit signed int.

Nothing wrong with the format itself.

extropy··on In defense of coding interviews
To add some thought to this.

The interview results need to be reasonably repeatable and comparable to assess interviewer skew and bias.

The result is that the interviews themselves inevitably end up being somewhat predicable. And what is predicable you can prepare for, giving you predictably better results.

If you are top 0.1%, sure you will nail them without much prep, but most of the candidates would spend some time preparing.

extropy··on Judge orders trial in Tesla autopilot manslaughter case
I'm confused - what allows the victims to sue Tesla directly? Legally the driver bears the responsibility, no? I can see driver suing tesla for a malfunction.

Can my neighbor below sue my washer manufacturer if they got flooded?

extropy··on Judge orders trial in Tesla autopilot manslaughter case
Not really. That a human driving in conjunction with autopilot enabled is far safer.

If anyone would read that as the car driving autonomy being far safer we would have fatal crashes every day.

extropy··on Ask HN: Why is Google Premium not a thing?
I spend way more time in YouTube than in search. If anything it should be the other way around.

There is the argument that many shopping decisions start with the search, but not sure if there is an order of magnitude difference.

extropy··on Will Hare replace C? Or Rust? Or Zig? Or anything else?
Does someone know how the str type works? From lang reference it's pointer/size/capacity struct but none of the examples does any freeing of strings.

What kind of magic is this?

extropy··on Will Hare replace C? Or Rust? Or Zig? Or anything else?
I lost the humble part at variable re-binding and automagical str type.

And does the job well at implementation-defined int size and a char = u8 (there is a rune type, so why bother?)

extropy··on Will Hare replace C? Or Rust? Or Zig? Or anything else?
Just a nitpick Clang is a specific C/C++ compiler implementation using LLVM, not the C language. Names are hard :)

extropy··on Gnome patent troll stripped of patent rights
Currently there exists a widely used "being used with hardware" hoophole that allows taking pure maths and adding a bit of hardware in there "a memory unit" "a processing unit" "I/O unit" and have a valid patent.
extropy··on I stopped advertising and nothing happened
Your time and mental effort are limited. And your own research is not that effective in areas you have little working experience.

In my experience a lot of older people (40+) increasingly rely on advice/influencers to drive their product decisions.

extropy··on Epic Games to donate all Fortnite proceeds for 2 weeks to Ukraine relief
3.8% of annual revenue that was ~5B in 2020. So somewhere in the 200 Million range.
extropy··on 1.0 USD = 158.3 Rub
Could be that the marked is getting split because of the sanctions and internal prices are diverging.

Similar in Soviet times there was a special internal rate that was very disconnected from international.

extropy··on Passwordle
No, winners never quit. Have to be true to your axioms.
extropy··on Developing a new app is unreasonable condition that Apple imposes on dating apps
Fair question.

If apple charged for the actual costs it would be a non issue.

Instead they charge 10x the industry fees for credit card transactions and gives the rest for "free". And that puts any app that has considerable running costs at disadvantage.

And gives competitive disadvantage to Apple's own products that get to pay for the actual costs.

extropy··on Swisscom to discontinue MMS service
Swisscom launched RCS a year ago. That is the next gen beyond MMS.

Also no sign up, no extra costs, handled by the carrier, needs a data plan though.

extropy··on Major breakthrough on nuclear fusion energy
Anything that is warmer than liquid nitrogen is room temp for scientists.

It's easy to produce, handling is well understood and cheap.

extropy··on Tesla cut a steering component from some cars, didn’t tell customers
That was never really a thing. More like a hope.

There was V2, v2.5, V3. With both compute and camera improvements. It's pretty much expected that you will need some form of hw upgrade if your car is >2 years old when the FSD becomes a thing. And it's included in the pricing.

extropy··on Microsoft Says Windows May Need Up to 8 Hours to Update
Oh no, laptops thermal throttle all the time. As do most of the desktops.

It's part of normal operation for any CPU/GPU released in last 10 or so years.

There is a reason why intel advertises a regular and "Boost" clock speeds. Boost clock is not sustainable without heavy duty cooling and the CPU will throttle down once it's heated up.

Kilo is always 1000. Kibi is 1024.

extropy··on 5.5 mm in 1.25 nanoseconds
Interesting. From what I could gather, latency in ICs is dominated by the time it takes for a voltage to build up at the sink, which is dominated by the resistances and capacitances along the way, makes sense.
extropy··on Google says iMessage is too powerful
Can I have WhatsApp that fallbacks to SMS though? Genuinely curious.
extropy··on PCI-Sig Releases 256GBps PCIe 6.0 X16 Spec
Yeah, using significantly cheaper but just somewhat slower hardware works great if you can parallelize.

Also cutting edge is usually very power hungry and power/cooling costs are majority of your expenses at data center scale.

extropy··on Speeding up my Advent of Code solution with Dijkstra's Algorithm
Fibonacci queue is a bit special that insertion is constant but extraction is log.

A-star is very insertion heavy. In easy cases with a factor of 5, so using Fib gives significant boost in performance.

extropy··on The software that flies SpaceX rockets and starships
Not mass, size.

You can still have a small but massive flying device and would end up with the same acceleration and jerk because need more thrust to zero the gravity out.

The bigger your thing is the relatively smaller the 9.8 m/s^2 is.

extropy··on The software that flies SpaceX rockets and starships
The manual controls are a separate system and would still work. And you can peer out of the window for navigation, Apollo style.
extropy··on Video of Tesla on Autopilot Crashing into Stopped Truck at 75mph
All radar based braking systems in the market filter out stationary objects because too many false positives.

To my knowledge there is no AEB system in production that could reliably avoided this.

extropy··on Man to sue parents for giving birth to him
Only if you have other income.
