Lightning can strike cars directly, and when it does, the couple inches of air and rubber between the car and the ground mean nothing (the tires sometimes explode, which looks neat when caught on video, if nothing else). Remember, the lightning travelled for thousands of metres through the air before reaching the car - another 4” of “insulator” isn’t going to stop it.

Now, if lightning were to strike the charging cabinet itself, I imagine that most of the surge current would go through the cabinet into the ground. If any were to make it to the chassis of the car through the charger, it would probably (“educated” guess) be at a low enough potential to not jump through the tires, but rather off some other low-hanging metal components. If it’s below the ~dozens of kV needed for that, charge will build up for a good fraction of a second, and dissipate over the next few seconds (or close to instantly if the ground wires don’t melt in the charging cable).

Really, the level of isolation in either the current case or proposed case doesn’t do that much to help with lightning strikes. They’re both designed to mitigate shock hazards measured in the hundreds to single-digit-thousands of volts. When the arc distance is measured in kilometres rather than centimetres, a 3” galvanic isolation transformer isn’t going to save you.

The solution for lighting is the same as it always has been: ideally, don’t get struck by lightning; otherwise, install a lightning rod nearby.

> If you read a few books on mathematics you think you're easily going to become one of the top mathematicians?

No, but so what? The guy behind 3Blue1Brown probably isn't one of the top mathematicians of his era. But he's having quite an impact. He turned explaining fairly basic math concepts in mathematics into a lucrative job.

And who wrote the textbooks you're referring to? Probably not any of the top 10 living mathematicians. That doesn't make the work less useful.

Is Linus Torvalds one of the top 10 computer scientists? He probably wouldn't describe himself that way, and respected academics mocked his work. The list goes on. I think this is compatible with the premise of the article: it's not about being best, it's about being better than the average bear - and then putting that knowledge to some productive use.
>>An unused sword rusts in its sheathe.

>>I dont think a manager of software engineers needs to code the application he manages, but he should be continually coding something to remain sharp.

I'd even go to the extreme of saying the coding skills/brains fade by inverse cube law. Skill =~ 1/t^3 (t = time since last practiced the skill). Musicians are known to say something along similar lines, like as little as a day of missed practice and they can feel it.

I used to be quite good at calculus as a teenager, and today I could look at the easiest problems there are and go blank. Only a faint echo of those days remains.

I have long suspected that Doctors suffer similar decline in ability as years go by from Medical school, and you can be sure in as little 2 - 5 years, most managers would struggle to imagine what writing code could look like.
Rockets Are Blasting the Environment

I like Michael Pettis's analysis, though I'll grant you that the distortions he cites in the Chinese economy have gone on longer than he predicted possible. But the health of the Chinese economy is not just the visible things you cite, but also the distribution of assets and balance sheets in the economy.

Per Pettis (and other sources), the banking system is dealing with a large debt overhang in society. Pettis's proposed policy fix is to assign that debt to the state, to state-owned-enterprises, or to the corporate sector. Because the long-term growth of China's economy depends on being less reliant on exports, and having a more "normal" mix of domestic demand. There are nuances there, but Pettis does a better job than I do in explaining it.

The trouble is that it's not politically expedient to assign the losses due to (unrealized) bad debt to those entities. And the result is a slow, grinding failure in the housing sector. The government does have a tight lid on dissent, but I understand that the Chinese people are in a more precarious position than they should be due to many households having overinvested in nonproductive real estate projects. How that unwinds will be fascinating to watch, and extremely relevant to world economics and geopolitics.

To be clear, I really am hoping for the best for China and its people. The right policy is sometimes well-known but hard to execute, and that's the tragedy. (It's playing out now, in spectacular style, in the US.)
Was your intention to prove the point about why it is important that more people host their own mail servers, or did you not realize you were?
Applied to ~45 jobs directly and got 2 interviews (my resume's fine, i think). posted here last month and got 8 emails within a week -> 3 offers. All at great companies/startups, uber-competent teams, and high-paying roles (like, double what public info shows). complete surprise too, since I was only looking for internships! Definitely a sample of 1, but I'm honestly completely flabbergasted by how helpful that one post was.
> Lightning strikes...how do EVs currently guard against it?

I mentioned further down-thread, but pretty much the same way everyone else does: don’t get hit by lightning, or have a lightning rod. A tiny transformer isn’t going to stop lightning, and it’s not supposed to.

Put another way, how do gas stations guard against lightning strikes? The concerns are roughly the same. The answer, in general, is “they don’t,” because they don’t need to.
The Wild West of AI Companionship
Your first paragraph is like saying "this train conductor does transportation, so we should let him fly a plane." Perhaps knowing security proves that the author is intelligent, and perhaps some of the same skills apply, but it's not a given that he will have good ideas, especially on fraught topics where it's easy to be misled by ideological bias. The author doesn't deserve any more consideration than any other outsider perspective.
Oh they would have tried if it wasn’t for that pesky commerce clause in the constitution
If it happens come back and read and think about this thread again (read my other comments in it). :) Promise I'll do the same if it doesn't happen.
Why do you think fuchsia is immature and/or experimental? It's been iterated on for nearly a decade and is deployed on millions of devices. Also why do you believe there are any MBAs involved in any decision making? Your understanding of how Google works seems to rely on faulty assumptions. It's also not clear why you seem to wish for Fuchsia to fail - having a Linux monoculture has all the same issues many folks argue against with other monocultures. Fuchsia succeeding will lead to improvements in all OS as they learn from each others advantages.
They wouldn’t
I think you are spot on. In 2022 Russia was pushed back from several areas and debating whether it would commit to a wider war. I think there were some opportunities for negotiation in early 2023 even to get favorable terms.

But yeah in 2024-2025 the tide has turned significantly toward Russia so it will be hard to get favorable terms. The challenge is that 2026 and on isn't likely to be different. Ukrainian Intelligence Head Budanov warned that Ukraine could collapse in 2025 if peace isn't negotiated.
I don't disagree. I definitely wouldn't want to be invested (or living) there.

But the point is that "collapse" is very different from "spent a ton of money on stuff that got destroyed."

The economic pain just isn't that high to force capitulation.
Well, I'm addressing the "real issue" part of your comment. Whether people switch over it is their choice (I've already switched to another browser as my primary years ago, and it's not Gecko, Blink, or WebKit). But just because other bad, worse stuff exist doesn't mean Mozilla gets a pass on trying to sneak in a license over people's own content as well as going back on their promise of not selling users' data. Or the history of terrible decisions they made.
Unless Europe steps in, or a peace is negotiated.

Responding to what I thought the parent comment was saying.

A more succinct point: the US economy looked really strong in mid-2008. Consumption was very strong, but it turns out that consumption was fueled by unsustainable debt.

China has a serious debt problem in its economy. Not government debt like in the US, but shadow banking debt. My fear, based on reading Pettis primarily, is that the Chinese people will end up paying for that debt. Households that have expensive second homes as investment vehicles will suffer those losses (since there isn't sufficient population to fill those homes), unless those losses are socialized or redistributed.
Yeah I just could not afford this stuff (debt) and I bought it used, $2K for a body, $2K for a G lens ... Then you get the urge to start buying all the primes...

I'm back to the basics now trying to produce videos with an Nex-5n it's not 4K but very cheap.

I follow the same policy as you do with all non-open-source software.

(With open source software, it's generally straightforward or at least possible to downgrade if something breaks… and I'm usually very confident that the software isn't being intentionally degraded on purpose.)

But folks like you and me are few and far between, and vendors and IT departments tend to be incredibly hostile to this approach.

The major proxy wars against the USSR were Korea, Vietnam, and Afghanistan. Korea was a stale mate, Vietnam was a loss, and then there's Afghanistan. It was certainly a victory, but I think that was more about the Afghans than us - the same reason we'd also go on to lose to them. They are one ridiculously hard and hardy people with completely unbreakable spirits. And of course the exact people we trained there would go on to form Al Qaeda, and generally form the backbone of radical Islam, which adds some further asterisks to that 'victory.'

Similarly the Soviets have pretty much always sucked at propaganda. The idea of a worldwide worker revolution attracted no more than fringe contingents. But US 'propaganda' of freedom of speech, capitalism, and so on played a key role in the eventual decline of the USSR. I remember listening to an ostensibly stoic Russian chess grandmaster who lived through the fall of the USSR. Him slightly choking up while talking about how grown men were tearing up over Donald Duck media, which had become a symbol of the end of one era and the beginning of another, was extremely memorable. Similarly this [1] is media from the opening of the first McDonalds in the USSR. They served some 30,000 people on day 1 at exceptionally high (relative) costs, with McDonalds flags working as thinly veiled proxies for flags of capitalism.

You still need to understand what you are selling, like in a very deep sense. Even if not at the technical levels, you need to understand how the financials of it all works, how to take product and sales roadmap forward. How to hire, fire, how to spend and on what to spend.

All this involves understanding the product in a very deep way, and a good deal of technical details as well. Else your staff will play you like a violin.

Absolute hands off abstract management by words won't cut it anywhere.

Coderag-Bench: Can Retrieval Augment Code Generation?
I love it. I have this whole system set up where each desktop gets its own session. So, any time I open a terminal on desktop 2, I get session 2. Then I can make all the windows I need (I very rarely split anything, but cool to be able to) and close the terminal when I’m done. When I open it again later, it’s all still there. I used to absolute overwhelm myself with terminal windows; now it’s all organized.
When it is blacklisted, the user/owner of the IP must go to each "anti spam" provider that blacklisted the IP. I.e. spamhaus, they have a page[1] to check if an IP is blacklisted as well as asking to remove the IP from blacklist.

When a fault occurs (say a battery fluid leak to the chassis) and is detected, a mechanical relay has to open to disconnect the power from the grid. That can take 200 ms or so, which is a long time to have 400v flowing through you.
I don’t floss every day but I do floss and frequently dislodge food caught between teeth or whatever. No one will convince me that leaving it to rot inside my gums and teeth is good. At the very minimum, it’ll stink.

I also occasionally develop a minor infection in my gums if I’ve not flossed in a while that flossing the area relieves. As a sample of one, it’s effective. If I do it it relieves the infection, if I don’t it doesn’t. Maybe my experiences don’t generalize but I suspect I’m not that rare of a human being. I generally have healthy teeth and gums, never have had cavities, and my dentist says she’s rarely seen healthier teeth especially at around 50. YMMV.
Would you do it if it was cheaper per kwh? Say you have an EV where any battery you get from the swap station is better than 90% degradation, and you pay $0.40 per kwh for the electricity in the battery- but you get the option to take a battery between 80% and 90% degradation, in which case you get the battery all filled up, but only pay $0.35 per kwh for the electricity in that battery.
I like the look of those minimal split setups. I'm currently using a planck half the time and an ergodox the other half. But because my brain has moved into the planck, more than 50% of the keys on the ergodox are just gathering dust.

My next step on this path, if I ever take it, probably resembles your setup. If/when I take it, I'll explore the modifiers on home row approach, it does sound nice :)

>Do you think people in Sweden or Denmark are upset their countries aren't hegemons?

Funny that you chose those two countries. Denmark is a founding member of NATO. Sweden is one of the two most recent admitted, almost a year ago.

My point is that it's U.S. hegemony that has protected its own democracy and that of liberal democratic Europe to a large extent.

Sweden and Denmark haven't been hegemons because they haven't needed to be.
This is on-par with asking how to keep using your 32-bit and PowerPC apps on MacOS. Not even OSX, but modern MacOS. The OEM is actively pulling support and working against you. There is no stable solution; at best you can have "This week we're doing X", and the correct solution is to move away from the unsupported software that depends on depreciated APIs that are being actively ripped out.

Having "no alternative" is one of the many reasons the open ecosystem we call the web, matters. Why having a single choice, especially one run by an ad agency, is a shite spot to be in. Unless you are willing to do your web browsing on an unpatched version of Chrome, or a fork run by a smaller team that "can totally keep up with Google's pace of development, trust us, those security patches made it in", you're kind of hooped.

Contaminants in fuel can cause damage to cars. I don't know if retailers tend to carry insurance for this but typically they are responsible, although proving it may not be easy. I imagine the risk would be quite rare and fairly well handled with insurance.

What's patented? Seems like a ridiculous patent if it entirely covered all practical manner of swapping batteries to recharge an EV.
Yeah, there's a known problem with smart, technical people approaching fields about which they know very little. The analysis, to a third party, often sounds smart (the author is undeniably smart!), but without having expert context, you miss why it's so, so, so wrong.

And I'm not even an economics expert. I've just read more about it, or read more critically, than geohot. And I can tell you he's wrong, not because he's an outsider but because his analysis does not make sense.

Copernicus had well-reasoned, self-consistent arguments that incorporated previous models, and produced better results. This doesn't. There is a rubric for how one should score outsider contributions, even if you want to allow for revolutions in a particular field. This essay doesn't rise to that level.

In fact, it matches the first pattern -- smart person outside their field, makes ass of self -- much better.

I was selected as one of the testers for MS Copilot for a large hospital in Florida after tested Microsoft DAX for a while (dog shit). Copilot has nice features, like customization of the sections, but I doubt anybody would spend time playing with that too much.

I tested 5 other Ambient AI tools in the past 6 months. All of them can extract the Chief Complaint and do a decent job with the HPI, but as soon as you get a more complicated case, they all fell apart. Sections like Physical Exam became a mess and I have to rewrite the whole thing.

So far the best, in my opinion, is still LucasAI by Lucas Health. Super simple to use, very basic interface. It just works and produces the best notes. I barely touch them. With the ICD10 codes, sometimes it doesn't pick the very best. This thing has been improved over the past month, but it's always much better than Copilot.

The AVS are both good, but with LucasAI I can translate immediately in Spanish and send it over to the patient via email/sms.

I haven't explored the integration with Copilot. Bad news, I know for a fact LucasAI is not fully integrated with Meditech yet, but I just copy and paste the whole note in 10 seconds. Not a problem. My buddy is using ECW and he said it's integrated. Haven't seen with my eyes.

Arc-fault protections are required primarily due to lobbying by receptacle and panel manufactures, not because they provide a real benefit. The number of people injured due to arc faults is vanishingly low, and a better solution to the majority of applications is to replace the NEMA 5-15 receptacle with almost literally any other (or at least improve upon the design). A more fitting comparison might be ground-fault circuit protections, which do very much have real benefits in all required situations without any drawbacks, while being very cheap to implement (effectively, a current clamp driving a relay).

On the other hand, feeding 7.2kV down a wire handled by very normal people in very normal (read: adverse; wet, humid, non-careful) conditions without any passive protections, relying on the portable (car) end to perform all of the shock safety is laughable at best. A bug in the car’s charging circuit (hardware, firmware, or software) and whoops, the chassis has 7200V to ground when the cable gets plugged in during a rainstorm.

Engineering safety regulations and guidelines are written in blood. Anyone who doesn’t understand that is either ignorant of the dangers involved, or narcissistic to the point of believing they are immune to danger.
