Honestly, I don't believe it. My family rented a plug-in hybrid BYD car this summer in Georgia (the country). Our combined luggage was definitely more than 40kg in total, and we had zero problems with that. It also looks like there are no mass complaints about trunk panels breaking.

BTW, the car itself was fine, not the most luxurious but also not the cheapest possible box. My issues were mostly with weak USB-C ports in the front and with the sluggish cruise control.

Blade batteries are still repairable. Re-celling a Model 3 battery is $6000: https://recell-ev.com/ so BYD battery repairs will likely be in the same range.

That's assuming it's out of warranty, which is now 150k miles or 8 years for BYD in the UK.

The largest other component is the integrated motor/inverter and they should be pretty reliable. They are still repairable, although you might need to replace the entire circuit boards, rather than individual components.

We already have stats for Tesla Model 3, and they rarely have problems with the battery and propulsion. So it's a trade-off, fewer parts also mean that you can overengineer them more easily.

There are also third-party replacements available now, because it's not that hard to manufacture most EV components, outside the critical high-voltage paths.

So you don't see past the leather seats?

(That approximately nobody outside the US really cares about)

Quite possible, especially with Let's Encrypt DNS challenges.
Can, but don't. It looks like on Android it creates a temporary link to the VCF file that needs to be downloaded from Google.
I loved IR contact/note sharing! It was easy, fast, and reliable. It also worked across different types of phones.

There's still nothing comparable :(

Re:Bidirectional Charging During Grid Outages on Sunday November 01, 2026 @05:30PM (#50330606)
Yes. Typically V2G works by connecting an external inverter to the high-voltage bus.

It just needs to start a charging session, and then siphon energy _off_ instead of supplying it. People tried that before, but the firmware on Model 3/Y monitors the flow and terminates the session if the flow is negative.

> So you claim that in the last 6000 years of history we had stagnation?

Yes. That's exactly my claim. Without instruments to support growth, the pre-industrial economy did not grow.

The European Industrial Revolution was kick-started by looted gold and other precious materials (like spices) that were looted from the colonies. It provided unexpected inflation by physically increasing the amount of available currency.

> I would claim the world economy did nothing but grow on asset-backend currencies - sure, there is some localized, small (as in relative to the timeframe) outliers that don't matter.

If you are bringing up 6000 years of stagnation, then our current economic growth is nothing but an outlier.

Re:How Do You Take a Picture of a Black Hole? on Saturday October 31, 2026 @05:28PM (#50320417)
The formation of the event horizon is also nothing special. If you are hovering (in a powerful rocket) on the edge of the future event horizon, then you are seeing highly blue-shifted light hitting you from the direction of acceleration. With highly red-shifted starlight from the other direction.

An event horizon forming in front of you doesn't change anything locally. You'll just find out that however much you try, you'll be moving towards the singularity with greater and greater speed.

A point-like particle won't be able to tell that anything is strange until it hits the singularity. But an extended object will break apart due to tidal forces that become infinitely large.

This is for a non-rotating black hole. I can follow the math for it, but rotating black holes are just too math-heavy for me.

So episodes of deflation that inevitably resulted in stagnation are "outliers" and thus don't matter.

> Or do you seriously claim we had stagnation in the thousands of years of civilization, and only started to have groth since 1971?

The economic systems have not been based on precious metals for quite a while. There simply has not been enough gold (or silver) to back up the economy for at least 200-300 years. Instead, the global economy was based on the _promise_ of getting gold.

In other words, fiat money.

> I'm sure it would notice the heartrate was up, but how is it supposed to translate that into energy consumption?

Well, you need more oxygen to burn more nutrients. This means faster heart rate.

The body normally doesn't want to waste energy, so the heart rate at any given moment is just enough to cover the requirements.

Precisely calibrating that is another story. You can go into one of the places that directly measure the oxygen use and get the baseline data (e.g. https://www.dexafit.com/services/vo2-max-testing )

> That is bs.

I assume that you're just completely ignorant, and as such, you can't be educated.

> Before 1971 we had a gold-backed monetary system

We didn't.

> and no record of deflation in the history of mankind.

Germany, 1932-1933. US, 1927-1933. And so on.

I guess that they're using multiple smaller towers? This does reduce the complexity of the tracking and alignment systems.
And the advantage of inflationary currency is growth. With deflation you only get stagnation.
Do you think money is transferred by shoving bank notes into the Ethernet cables?

When you transfer a dollar from your account to Putin's account in a Russian bank, in reality your bank transfers a dollar from their account within the FRS (Federal Reserve System) to Putin's bank's account within the FRS.

It can be more complicated with more intermediaries, but it can be traced and reverted.

> Infallers are not smeared across the horizon. They are if anything asymptotically "frozen" in the distant observer's view.

They also get dimmer and dimmer. The same amount of emitted (or reflected) radiation gets spread out over longer and longer periods of time.

In reality, the light is also quantized, so it doesn't take that long for the last emitted photons to escape.

Re:How Do You Take a Picture of a Black Hole? on Friday October 30, 2026 @06:20PM (#50310879)
That's not how black holes work. It takes an infinite amount of time for the light at the event horizon to escape, true. But you can think of it as if it's an "optical effect".

If you are a free-falling observer, _nothing_ changes for you locally at the event horizon. You will cross it and reach the singularity within a finite (and quite short) time.

As someone studying for a pilot license, your take is literally ridiculous.

You should perhaps look at all the crashes where the autopilot stalled the aircraft on approach due to incorrect settings.

Uhh.... What? The wheel diameters for cars and trains are similar. The amount of slippage also seems to be the same.

You also can get periodic absolute fixes to correct for the accumulated drift.

Re:If IPv4 Were Land on Thursday October 29, 2026 @09:53PM (#50298935)
> The only ways you'll get multiple addresses for a given host are to either hard-code them, or use DNS

mDNS exists. As does SIP and SMB.

I first discovered the ULA/GUA issue when my TimeMachine backup dropped mid-session when I was testing Internet connection failover. Apple later fixed it by allowing multiple SMB sessions in parallel and preferring IPv4 connections. I have a pure IPv6-only network, as I said.

The same issue happens with SIP, as phones send their own addresses during the media connection negotiation.

(I have another funny story about SIP: Asterisk used to send a Cartesian product of available codecs and IP addresses, so if you had IPv6 privacy addresses on, it eventually accumulated enough of them to overflow the MTU, causing connections to silently drop)

> Does your phone's GPS work in a tunnel?

My car's GPS does, using dead reckoning.

Trains can also use dead reckoning.

/me checks notes, I've heard that they move on inflexible things called "rails" that almost never change the location.

Ah, brings back memories. We did a New Year's school theater presentation in the third grade, playing out the "painting the fence" scene from the book.

In English, which is NOT my native language. I had to memorize my lines without understanding half of them :)

Re:If IPv4 Were Land on Thursday October 29, 2026 @08:23PM (#50298249)
I'd argue that it's still not mature. ULA/GUA mess is one example, I recommend reading this delightful thread with beer and popcorn: https://mailarchive.ietf.org/arch/msg/v6ops/7-SuigPyP0R-C6ZC...

Having to waste 64 bits for the local part of the address is another one. There's an RFC in progress to allow neighbor discovery with shorter prefixes, so we might be able to use it by 2045.

And Android _still_ doesn't support DHCPv6.

Re:If IPv4 Were Land on Thursday October 29, 2026 @07:00PM (#50297453)
> Why isn't your DHCPv6 server putting either both the GUA and ULA, or -better- only the ULA addresses in your LAN's DNS server?

I don't have a LAN's DNS server or a DHCPv6. BTW, I have had an IPv6-only home network for 10 years, with NAT64 and 464XLAT.

You still haven't solved my puzzle or even understood what's happening. The current source address selection rules result in hosts prefering a GUA address pair over ULA. This _will_ result in broken connectivity when GUA addresses change.

There is currently no standards-compliant way to solve my challenge, except getting an ASN, an IPv6 assignment, and announcing it through your uplinks. Which I've also done in my home network, btw.

There's an in-progress RFC to change this, by preferring ULA-ULA address pairs over GUA-GUA. So it might be usable some time in the 2030-s ( https://www.ietf.org/archive/id/draft-ietf-6man-rfc6724-upda... ).

And no, this is not a theoretic problem. It affects protocols like SIP or even mDNS that exchange the IP addresses. They will consistently prefer unstable GUAs over ULAs.

Re:If IPv4 Were Land on Thursday October 29, 2026 @05:55PM (#50296683)
ULA are useless for most practical purposes because of the source address selection rules.
Re:If IPv4 Were Land on Thursday October 29, 2026 @05:40PM (#50296481)
OK, do you _think_ my questions were that easy?

> Advertise the addresses offered by the primary uplink, then retire those addresses

Prefix withdrawal doesn't work reliably on Android. And neither is it required to work, btw. Neither does this solution allow for load balancing, as all traffic will just go through one connection.

Bonus points: triangular routing to your local NAS through the router.

> How do you prevent your printer from "breaking" when its ISP-provided DHCP lease on its globally-routable IPv4 address expires? How about when the ISP refuses to renew the lease on the printer's current globally-routable IPv4 address and forces it to get a new one?

Printers get an RFC1918 address and don't care about global connectivity.

> How to solve this with IPv6? Use ULAs! They're the equivalent of 1918 space in the IPv6 world.

They're not. IPv6 is nothing like IPv4 operationally. Back to my challenge, ULA will NOT work.

The scenario is very simple: the printer gets a ULA prefix and a GUA prefix. Your computer also gets a GUA and a ULA from the same router.

So far so good.

Now the uplink goes down, and the router withdraws the prefix. The printer sees the withdrawal and removes its GUA address. Your computer misses it, and still has the GUA and the ULA addresses.

Whoops. The printing is now broken somehow. Why?

Re:If IPv4 Were Land on Thursday October 29, 2026 @05:06PM (#50295988)
You're welcome to try to solve the challenges from my sibling post. Both of them are solved in IPv4 by a $100 router from a nearby store and with zero configuration.

> I don't get your point. IPv6 is at "boring, just works". The majority of the worlds devices run on it dual-stack and it handles a considerable amount of traffic.

Most of the world runs on IPv4. If we shut down IPv6 on the core routers tomorrow, pretty much nobody is going to blink an eye. And now I believe that we should do it and start again.

The 50% stat is really mostly mobile phones on cellular networks, which remain the _only_ major success story for IPv6. Mostly because there's not enough private or even squattable IPv4 space available for many large mobile phone operators.

> IPv6 is very much alive. And it's so boring and working so well, that you don't even notice it.

Sigh. No, it's not. In a thread a couple of weeks ago, I gave several examples:

1. You're a SOHO-type business. How can you do multiple WAN uplinks with IPv6 without NAT?

2. How do you prevent your printer on IPv6 from breaking when your Internet connection goes down?

For context: I deployed IPv6 in my networks in 2006. I have war stories.
