"range extender cells" == shorter recharge lifetime cells that are only supposed to be used in 1% of trips (long ones). I wonder if these are just experimental low-cycle cobalt/nickel or some other battery that normally isn't up to the cycle endurance of a consumer car.

LFP for an everyday usage (200 miles in a day), which are high-endurance, good temperature range, safer, etc.

I think this mixed mode is an excellent example of how "good enough"-density (200 wh/kg) LFP (and possibly even cheaper sodium) will be utilized.

All these different cell chemistries can each be combined in heterogeneous packs for different use cases. So even if a cell can't do 1000 cycles, it might be usable for the rare trips. Or maybe make that high-density module more replaceable, and the long-endurance LFP/Sodium does Cell-to-Pack and that type of stuff.

I think a typical consumer car in a few years will use a sodium or LFP for about 2/3 the cells (by weight/space) and 200 miles of range, and another higher density SSB or modern cobalt/nickel high-density cell for another 200 miles of range.

So the question is, what was the mix in this car? That's the big question.

ipv6 is hardly an abandoned standard, 35% of google users access google over ipv6, and it continues to grow every year.

https://www.google.com/intl/en/ipv6/statistics.html

IPv6 is also usually faster than ipv4 these days, because the overhead of fragmented ipv4 routing is large. In the past it was slower because of lack of understanding/support for it from larger ISPs, and consequently poor routes, or really suboptimal tunneling setups.

Let me make a point... A couple centuries ago the similar story unfolded with some Galileo fella. I understand a few chaps were even burnt at stake (yikes!). The spat was about some astrophysical matter, and it was obvious to everybody that the guy is spreading misinformation. Just a little problem - turns out Galileo dude was actually right. Sorry ¯\_(ツ)_/¯ ...

So, how do you know you are even on the right side here if instead of debating the matters you just want to shut the guy up?
Flat orgs are very popular right now, but isn’t it a huge benefit of a hierarchical organization with subparts that rather than the President of Azure getting on a VTC and telling the whole division that the goal is velocity he can explain to his reports (a small group) that they need velocity with reliability and they can explain to their reports (more small groups) and so on and so forth?

Yes, nuanced comms don’t scale so why isn’t the answer—-don’t require scaled comms?

LFP charges pretty well since it is so much safer.

I'm not sure what the point of tenured crypto researchers patenting their crypto is. The only thing it guarantees is that your crypto is barred from standards because crypto is so extremely widespread that collecting royalties is simply impossible. AES-OCB is a prime example of this. It was faster than GCM and not quite as brittle, so many people would've liked to use it - but it was patented. No one used it. It now has a non-commercial FOSS patent grant, which still means no one uses it.

> The number one complaint I hear (and have myself) is that maybe I don’t _want_ all devices on my LAN to have public IP addresses.

This isn't a goal in itself. The formerly problematic and unwanted side effects of NAT, namely a broken peer to peer relationship of hosts on the internet, are now understood as a feature. Machines were forced by this technology to be clients and the initiators of all connections to the internet. Historically this has interfered greatly with several internet protocols (ftp, IRC DCC, p2p file sharing, ...) all mostly dead now or reworked to operate in a world full of NAT gateways.

IPv6 would reverse this state of affairs. If machines need to be denied the server role, this can be enforced by a firewall. As far as tracking of clients by IP goes, dynamic address assignment via DHCP or IPv6 privacy extension take care of that.
A thirteen year old having low bone density, heart problems and degenerating joints would be strange, but for someone > 70 it’s almost expected. The car example is dumb because cars don’t have a built in mechanism for regeneration that is failing. Our bodies mechanisms for self-regeneration weaken and then we see all the symptoms of aging.

Brief-ish TLDR (note: I am summarizing what Daniel Bernstein says in the linked article, and make no comment on its correctness; this is relevant because Bernstein makes some accusations about another academic) --

Back in 2016, Google began an experiment with "post-quantum cryptography", deploying some cryptographic algorithms in Chrome and in Google's servers that should be resistant to attack by quantum computers. (Most present-day crypto would be very badly broken if non-toy quantum computing becomes practical.)

But they shut it down after a few months, even though it seemed to be working well. They'd originally said that if it went well they'd find a better algorithm and switch to it in a couple of years. So what happened?

Plausible answer: shortly after beginning this experiment they were contacted by a cryptography researcher (Jintai Ding) who holds a patent that allegedly covers the algorithm they were using. The easiest course of action when this happens is just to shut the thing down.

So how come they didn't know about this patent?

Plausible answer: because another cryptography researcher (Chris Peikert) deliberately and systematically misled the academic community in order to avoid them noticing Ding's work -- because Ding did an important thing in 2012, and Peikert did essentially the same thing in 2014, and Peikert wanted to take credit for inventing it. Peikert succeeded, everyone thinks he invented the relevant things first, and no one thought to check whether Ding might have patents on it.

(I reiterate that I am summarizing Bernstein's claims, and I do not know whether they are right or not.)

TLDR of the TLDR: according to Bernstein, a dishonest academic cryptographer went out of his way to deceive his colleagues into ignoring earlier work by another cryptographer, so as to get the credit for it himself, this led to an important patent being overlooked by Google, and this has been a completely unnecessary stumbling block in the way of getting post-quantum cryptography deployed, so that Peikert's (alleged) selfishness and dishonesty have made everyone's data much less safe against future quantum-computer-based attacks.

Why should the battery in the Dacia be so much worse than that in a Leaf or Tesla. Surely there can't be that much variation in battery quality within the major Western manufacturers (Dacia is a Renault subsidiary I think).

My 2015 Model S 70D which has done over 160 thousand km seems to have pretty much the same range as it had when it was delivered (about 330 km) so if the decline is more or less linear from the start then the lifetime is actually rather longer than the manufacturers expected. Of course I suppose it is just possible that it will die on the day after the eight year warranty is over or perhaps drop to 70%! But how likely is that?

And surely once there are a lot of old EVs on the road there will be a big market for replacement batteries and competition will drive the prices down.

I work at an ayahuasca retreat center in Peru, and childhood abuse is one of the more common things people come here to work on. Often people will arrive with rather "generic" intentions for their stay (e.g. anxiety or depression) and will often discover after a couple ceremonies that childhood wounds had created broken patterns that have governed their whole lives. It's often shocking, but once the realization is there the healing work can begin. IMO, the traumas don't have to be permanent, as the intro to the article says. Ayahuasca isn't necessary (though I do think it's quite a boon to this work!), therapy can be sufficient for many. Don't be afraid to get help.

> Some features might be around support for things like Unicode where a tool could work 90% of the time but that extra 10% of support requires implementing a lot of additional logic that slows the routine down for the other 90% of use cases too.

This kind of thing is where Rust really shines. The ecosystem was built post-unicode, so things tend to support it by default. Ripgrep for example has been unicode aware from the beginning, and you have to opt-out if you don't want that.
Haskell automatically imports all typeclass definitions (equivalent to traits) when you import a module, so you sometimes see lines like

`import Foo.Bar ()`

Which looks like it's just importing nothing at all (`()`) but is actually pulling in some traits and nothing else.

You don't see this often because "orphan instances" (instances defined in a file besides the location of the trait definition or the type definition) are discouraged, but they do occur.
It's "perfectly valid, fine" with the exception that it's different from how the vast majority of Rust programmers write code. That in itself is a problem. Rust has two widely-used tools that enforce style: `rustfmt` and `clippy`. The former enforces formatting style and the latter general programming style, such as whether or not to use a `return` statement (`clippy` also does non-style lints).

For many of these formatting/stylistic lints, there are valid arguments to be made for an alternative choice. I personally often disagree with one or both tools. I still follow them.

The huge benefit here is that most Rust codebases look identical. I can open up burntsushi's regex crate and see code that is formatted and styled exactly like mine. It makes reading new code a lot easier.
>Is that "a" caretaker, or a team?

Like anything else, the team size would vary, based on workload.

When I was a kid, the big guy would approach me and pretend to hit me in the face, but stopping a fist an inch from my face. He was saying: "what am I - not supposed to move my hands?

Half the discussion is FUD that a consumer router wouldn't have an IPv6 firewall.

Your router, like every other, has a default deny firewall for IPv6. You'll find the settings near to where you set up IPv4 port forwarding. My router calls it "pinholing" or something.

Then you can SSH directly to the servers you allow access to, using port 22 for all of them if you wish.

I experienced extreme physical abuse when I was 3 (my babysitter used to shot put me across the living room when I wouldn't take naps.)

A lot of what is in this article, I can attest to firsthand. I didn't realize I had been abused until I was 15, as I had stifled the memory, and though I remembered it, it never "clicked" as abuse before then. I've had a host of mental health problems that have led to me being diagnosed ADHD/bi-polar in my early teens, with the latter being renegged as too hasty of a diagnosis.

Today, I can't get a diagnosis, as I don't have enough symptoms in each category to fulfill any one (BPD vs DID vs PTSD). It feels like I have some kind of grab-bag illness of all three. What's more, the medicinal options available to me are awful, and cause me a whole host of different problems, both physical and mental.

What I'm trying to say is that - as someone dealing with these problems - it still feels like there's a long way to go before I have any real options towards improving my mental health. I'm very hopeful for the increasing popularity of THC/CBD for the treatment of trauma, as I've found that to work wonders for stopping/avoiding psychosis. I've communicated this too all my doctors, but it's never been taken seriously. I am "prone to drug abuse" after all.

Got me wondering how this compares with neural efficiency, realizing ofc that there's nothing really apples-to-apples here.

Training one of these big models takes 100kWh for 1e19 flops, so that's 100k Wh, 360M Ws, or 360MJ or 3.6 1e8J. 1e8Joules/1e19flops = 1e-11J/flop

Neurons take 1e-8J/spike.[1]

Math check appreciated :)

Does seem plausible to think of a single neuron spike (hodgkin-huxley cable model) being modeled with ~1k flops. Though I'm firmly of the opinion that nobody really knows how the brain works.. the neural spike activity could be pure epiphenomenon.. who knows!

[1] “Finally, the energy supply to a neuron by ATP is 8.31 × 10−9 J. Meanwhile, integrating the total power with respect to time we will get the consumed electric power, which is 8.75 × 10−9 J. This is more energy than the ATP supplied. The energy efficiency is 105.3%. This is an anomaly…” - 2017 Feb 16 Wang, Xu, Institute for Cognitive Neurodynamics, East China University of Science and Technology

Totally agree. The UX for IPv6 sucks. Every time I poke with it I get worried I'm exposing the guts of my internal network onto the internet. With NAT, at least I know nothing is getting in without me intentionally punching a hole. With IPv6 to do the same I have to go fiddle with the router's command line interface and rules by hand. And even then who knows if I fucked something up or missed something... its just a lot of work.

There is no web UI for managing IPv6 firewall rules but there is for IPv4. On the consumer grade routers I've touched there isn't even a way to configure the IPv6 firewall rules (and again, they all offer web UX for IPv4 rules).

Does that explain the level of nuance around public health policy?

Covid policy for example. Some countries take into account natural immunity (more nuance). Others don't and simply require everyone to be vaccinated regardless (less nuance). Some recommend or even require kids to get the Covid vaccine (less nuance - everyone take it), other countries recommend against (more nuance - some should, some shouldn't). They all have access to the same data. Is this simply reflective of a different approach in communication? Or a different level of confidence or respect for the population to grok nuance?
If I provided users with an IPv6 block to allowlist for my apps, I think most IT directors' heads would explode, but _everything_ works with 32 bit CIDR ranges.
