It’d be a massive waste of electrical conductors to use 48V batteries due to ampacity. Higher voltage means lower ampacity and smaller conductors.

You’d need to use silver plated copper buss bar as conductors, 150kW @ 48VDC is 3125 Amps. I’m not familiar with DC ampacity tables, but you’d need (9) 3” conduits each containing (3) #500 MCM conductors for a three-phase 3125A alternating current circuit. One foot of #500MCM copper weighs 1.5 lbs, so each foot would have 27 times 1.5 lbs or 40.5 lbs per foot.

150kW @ 400V is 375A, a single set of #500MCM can carry the current, 4.5 lbs per foot.

The risk of being shocked by 400VDC while using the car is essentially 0, so they use higher voltage to save on conductor material.

There’s no way in hell I’d ever open up an EV battery myself and I know enough to do it safely. DC is incredibly scary, make sure to discharge your start/run caps if you replace them yourself!

That site doesn't seem to have a way of objecting to the term ''Eskimo'' to describe Inuit peoples. In Canada, that term is now seen as pejorative and linked to colonialistic abuse. It has become out-of-favour, distasteful, and essentially obsolete. In the USA it is also problematic, as described in Wikipedia's ''Eskimo'' entry.

Friend, hunter-gatherers felt more existential dread than you do, because 50% of their kids died, and they themselves would be lucky to live to the ripe old age of 40.

Every generation in history has felt that things used to be better and they got the short end of the stick. My grandparents lived through the Great Depression and World War II. My parents lived through the cold war, Watergate and Vietnam. Millennials have phones that they like too much, and it's slightly harder to buy a house, and they feel like no one has ever endured this much hardship.

We need to grow up. "Too much Instagram" is not remotely on the same level as "we need to hide in the basement during air raids."

PS, I don't buy any argument that there's more depression now than there was at an earlier point in history, because psychology does not have the most stellar track record when it comes to scientific rigor. I just don't trust any measure that's over 20 years old.

I‘m sorry but this may come across as condescending, but if you are a financial analysis, isn’t doing statistics a part of your job. And doesn’t your expertise involve knowing which kinds of statistical analysis are available to tackle a given problem? It just seems weird to me that you would opt to not use your expertise and instead use a generalized model which is both more expensive and has poorer results as traditional models.

Yes, I think when you work in implementation, it's obvious that you made a bad decision (to yourself before others see it) and you are quick to say "I made a mistake, let's fix it before the mess gets worse". Your skillset in this hypothetical I'm creating is "implementation". You decided on the implementation but that's only part of the entire thing you are responsible for (plan, build, maintain).

For execs they are responsible for monitoring key indicators and deciding on what to do.

When things go wrong it could be they weren't monitoring the right things and missed it or the direction the took initially was wrong (either right away or as things changed and they didn't see it).

That's their entire job, more or less. Not trivializing it. The stakes are high pretty often.

While I'm not sure the particular price point is the biggest problem here, the student license pricing doesn't feel seem that great either. The language is hard enough to learn, and most students won't have time to figure out if they want to buy it with a 15-day trial. They'd probably need half a semester at the very least, unless it's a required part of the curriculum. In the rare case where a student is already familiar enough to know they want it, then four years of $75/year is $300... at that point they may as well just pay $390 for a perpetual personal license, so they can at least keep opening their files in the future.

That said, the parent was talking about it being expensive for use in industry. Personal and student licenses aren't relevant there.

As I said before in another thread [0] This is the way to go, what we need are modular open standards for both hardware and software.

Imagine a phone that you can just swap and mix components from different manufacturers. You could buy the components yourself and assemble, like a standard PC. If one manufacturer tries to lock you in, or you don't like their component you simply replace them with others from a different manufacturer.

I see - thanks for the explanation. I try to filter out those sorts of ads too, because I don't want my decisions to be biased by the money someone else spends, but they certainly are less annoying than the usual sort.

I wonder whether you would consider ads for fashion houses in a fashion magazine to be "solicited" or "unsolicited"?

Put yourself in their place for a minute. There's a thousand to-dos, including this Bluetooth pass-through feature. If you try to get around to all of them, you need to hire more people, either telling them up front that you won't be able to pay their salary or just not mentioning that until after they've done the work. Or you need to find more paying customers, but you're already trying to do that. Every minute spent on that also is a minute lost on making a better product. How to allocate the available time optimally? It's not as simple as "they're ignoring the community completely".

Saying that this is not a product for you because there's other devices out there without this problem: entirely fair, but that's not the same thing

> This is a very strange failure of reading comprehension. I think you're trying to write "I will only give you food if you're white."

No. I am exactly pointing out why your example, which would be analogous to "I will only give you food if you're white", is not comparable to "I will give you food, on the condition that I can punch you in the face".

Anyway, you are still missing the point. You cannot cause harm to someone by offering a bad option. These are not the same kind of statement. The race-based one is not an offer. It does not involve any possibility of food being given to the black person, because the black person cannot become white. It is not comparable to the offer to be punched in the face, because the offer to be punched in the face is an offer.

> If that's your ethical standard, I have nothing more to say.

The failure of reading comprehension is yours.

> If so, that would be why. A lot of places here get quite cold.

Heat pumps in Alaska:

* https://www.adn.com/business-economy/energy/2024/09/01/energ...

However, before spending money on new mechanical units, it's usually better to improve insulation and air tightness first: there's no sense heating (or cooling) and then have the conditioned air leak in/out of the house.

Further, there are hybrid / dual-fuel systems: you operate the heat pump down to X ˚C and at that point switch over to burning something.

All that said, heat pumps can be used up to at least IECC Zone 5, and with a decently insulated house in Zone 6 (you probably need pretty good insulation to get into Z7):

* https://basc.pnnl.gov/images/iecc-climate-zone-map

* https://basc.pnnl.gov/resource-guides/cold-climate-heat-pump...

* https://heatpumpdata.energy.gov/data/studies/nrel-field-vali...

There are certification for working down to -15C/5F:

* https://neep.org/heating-electrification/ccashp-specificatio...

And while there are areas of the world where it gets that cold, how many people live there (relatively speaking)? I would hazard to guess that large portions of the human population (even in the US) do not live in areas that get much worse (on average) than -20C/-5F, and so large portions of the population are eligible for HP use. (And I'm saying this as a Canadian.)

When deciding on what kind of heating/mechanical system to get, many building codes dictate that you have to design around how much energy you house will need for you area. The historical data is readily available (left-click to scroll, right-click to choose):

* https://ashrae-meteo.info/v3.0/

For heating see "Heating DB 99%" (which means that historically the temperature has been warmer than the listed value 99% of the time, i.e., except for ~4 days out of any year (on average)); for cooling, "Cooling DB 1%" (historical temps have been lower except for 1% of the time).

This is great! Especially nice to hear as I'd been all to aware of the advice to not rewrite your whole codebase once you raise some money as that's an easy way to tank the company. As a result I have probably erred to much on the type of refactoring he compares this to.

More recently I have been more aligned with the shredding approach. I think one of the reasons that it works that isn't mentioned here, is that often you only really know what's needed after finishing the first implementation and/or using it for a while.

I'm also reminded me of the Japanese practice of rebuilding a temple every 20 years: https://longnow.org/ideas/long-term-building-in-japan/

You can specify a commit, yes, but how do you remember your set of unnamed commits? Once HEAD no longer points to a commit, it will not show up in `git log`.

I agree that Git could gain an operation log. I haven't thought much about it but it feels like it could be done in a backwards-compatible way. It sounds like a ton of work, though, especially if it's going to be a transition from having the current ref storage be the source of truth to making the operation log the source of truth.

On the other hand, "slow is smooth, smooth is fast". Which strategy is optimal depends on the nature of the product and the cost of iteration.

In software, optimizing for speed works best in cases where architecture has minimal relevance for product outcomes. If I am writing a Python library then I typically iterate very quickly. Swapping out bits of implementation has low cost.

If I am writing a database kernel then designing any part of it poorly has a high chance of permanently crippling the implementation. Iterating is often tantamount to a major rewrite and extremely costly. You can only afford a very small number of rewrites before the iteration time stretches into years, so it is actually faster to spend much more time thinking through details that may seem unimportant.

> Or just buying from the existing European providers? Most American gear has a (sometimes better, cf. all the stuff even the US buys from European companies) European based equivalent.

That might happen over the long term (I still have doubts given that whenever a joint EU project is formed between two countries with vendors, they inevitabely end up collapsing due to domestic political considerations such as the European MBT and FCAS - no leader wants to be the leader who shut down a factory with 1200 high paying unionized jobs for the greater good), but cannot happen in the 1 year timeframe given.

The reality is, if we the US make a deal with Russia over the Russian invasion of Ukraine in the next 12 months, the EU will have no choice but to accept it if you do not put boots on the ground and if you do not expropriate Russian government assets in the EU. But your leadership class has rejected [2] both [3].

> European manufacturers need to increase output, and they have been working on it and have done so quite a lot already.

Not enough for the 1 year time frame needed

> how the DSA is supposedly a negotiating tactic from the EU any more than you could say that about GDPR

We view the DSA as a non-tariff barrier to American services companies. This is both a Trump admin view [0] as well as a Biden-era admin view [1].

We held similarly negative views about the GDPR until Ireland, Czechia, Poland, and Luxembourg accommodated us by hiring our lobbyists as their commissioners.

And this is why every single pan-EU project fails - every major country like the US (previously listed) and China [4][5] cultivated economic and political ties with members that act as vetos in decisions that have a unanimity requirements.

This is why I gave the comparison to the Qing and Mughal Empire - the English, French, and other European nations broke both empires by leveraging one-sided economic deals with subnational units (eg. the Bengal Subah in the Mughal Empire and the unequal treaties in the Qing Empire), which slowly gnawed away at unity.

We in the US, China, Russia, India, and others are starting to do the same to you - not out of explicit strategy, but due to the return of multipolarity and most European state's failure to recover from the Eurozone crisis.

I don't think HTML is the right approach. HTML is better than PDF, but it is still a format for displaying/rendering.

the actual paper content format should be separated from its rendering.

i.e. it should contain abstract, sections, equations, figures, citations etc. but it shouldn't have font sizes, layout etc.

the viewer platforms then should be able to style the content differently.

I also don't see a reason to get one as an average commuter driver. But if you have a fleet of cars as a business: delivery, in-home nursing, cleaning services, etc, then the fleet owner can use stats about their drivers and routes for optimization (or micromanaging their employees to death) or use the driver safety data and presence of reliable dash cams to negotiate better insurance policies. Meanwhile Bee Maps profits off your subscription and selling the map data to third parties.

Also porn is related to free speech.

There is no need to be a puritan against any form of pornography to expect consensus against having most addictive/eye-catching porn ostensibly displayed everywhere in the public sphere. And it’s perfectly clear that it’s actually possible to be simultaneously fine with people watching all the porn they want in their private sphere if they are warned willing adults.

IMNSHO she didn't admit and correct the mistake — yet. She admitted one mistake and has corrected none, and the one she admitted was IMNSHO not the severe one.

She made several mistakes, of which I'll describe two. One (modestly serious) was to confuse units and compute the wrong number. The second (against my religion) was to publish without sanity-checking. You and I both know she didn't check, because her estimate for the average water use of one building was 20% of the water use of the continent. Any sort of check would uncover that mistake.

We in the rational camp are supposed to behave differently from Alex Jones, and part of that is to check before we publish.

She's "making arrangements with her editor to rectify the situation". If she fixes every reported error, not just one of them, I'll have a lot of respect for her.

What separates capitalism from earlier forms, e.g. guilds in the middle ages is that every person can decide to make their own business at any time. Nobody is predestined to a specific profession or estate. That not everyone has its one business is because not everyone wants to do that managing work, some people want to do productive work and a lot of projects are larger than a single person could do.

That work can be exchanged for money predates (the current form of) capitalism and depends fundamentally only on the concept of money alone. I fail to see how that is exploitation per se. You choose to trade something you have for something you want. That's freedom. Taking that away means slavery or starving people.

> The state maintains this exploitation of workers’ productivity through so-called property rights - the “rights” of the business owner over the worker.

What are you talking about? What "rights" of a business owner? The only thing they make are voluntary contracts. You are doing the same when you buy groceries, you are trading money you have for the work of others. What you describe is (wage) slavery, which we claim to have abolished.

Yes they are property rights, but show me the person who doesn't have property. I bet even the homeless person doesn't want it to be legal that the few processions he has can be taken away by anybody, because they just want it.

In civilized countries employees also have more rights than employers e.g. for notice periods, precisely because the working market is often in a state where the employee has less negotiation power. The contract drafter is also the disfavoured party in court.

It is, and intentionally so.

NiCd batteries could also sit on a shelf forever, holding their charge. They had virtually no self-discharge, which was super-convenient.

They came in standard form factors (AA, AAA, 9V, etc.).

I really liked NiCd batteries.

But realistically, you couldn't sell a phone or laptop in 2025 which ran on them.

So, I wanted to use tailscale for a few local services in my home, but I run a few of them on the same device, and have a simple reverse proxy that switches based on hostname.

Afaict I can't use a tailnet address to talk to that (or is it magic dns I'm thinking about? it was a while since I dug in). I suppose I could have a different device be an exit node on my internal network, but at that point I figure I may as well just keep using my wireguard vpn into my home network. I'm not sure if tailscale wins me anything.

Do other people have a solution for this? (I definitely don't want to use tailscale funnel or anything. I still want all this traffic to be restricted like a vpn.)

Let me empathize but say, to put it bluntly, they do not have qualified IT Staff. They have 1 or 2 people who understand only basic web server stuff and nothing else. Thus the two week outage.

Paying LearnWorlds + Shopify $30K a year, if it were even that extreme, is cheaper than an engineer and certainly cheaper than an outage over Giving Tuesday, as they found out the hard way. They got hacked and were down for the most high-traffic nonprofit donor day of the year in their effort to save a few bucks. It wasn’t even the plugins, but the instance underlying the shared hosting.

> It's literally always the same. They get you running in no time, and in no time you're locked into their ecosystem: No customization if they don't want it; pricing won't scale and just randomly changes without any justification; if you do something they don't like they'll just shut you down.

You’re also locked into an ecosystem. It’s called Stripe or PayPal. Almost all of that applies anyway. Don’t forget that significant amount of customizations are restricted to streamline PCI compliance, you can do illegal things very easily. Install an analytics script that accidentally captures their credit card numbers, and suddenly you’re in hot water.

> Leading to huge dependencies, vendor lock ins, monopolies, price gauging

Have you analyzed how many dependencies are in your self hosted projects? What happens to them if maintainers retire? How long did it take your self hosted projects to resolve the 10/10 CVE in NextJS? And as for price gouging, if it’s cheaper than an engineer to properly support a self-hosted solution, I’ll still make that trade as even $80K for software is cheaper than $120K to support it. If you’re at the scale where you don’t have a proper engineer to manage it, do not self host. Business downtime is always more expensive than software (in this case, 5 salaries for 2 weeks to do absolutely nothing + lost donations + reputational damage + customer damages, because “self hosting is easy and cheaper”).

Mostly, yes. It also covers changes to the working copy (because jj automatically snapshots changes in the working copy). It's also much easier to use, especially when many refs were updated together. But, to be fair, it's kind of hard to update many refs at once with Git in the first place (there's `git rebase --update-refs` but not much else?), so undoing multiple ref-updates is not as relevant there.

AV2's mission is to nip VVC in the bud. They seem to be more or less at parity, and given that, why would anyone want to use a royalty-based codec when they could could use an essentially equivalent free one? There's no massive hurry to implement either - we have existing codecs that are largely good enough for now - this is technology which take 5 to 10 years to fully deploy, as has been seen with other codecs.

If you have skills and see opportunity then going for that may result in nice outcomes :)
