I may be full of crap, it's been over 15 years since I worked on this stuff. You have been warned.

The systems I worked on used multiple deep discharge, cold weather hardened lead acid batteries.

Deep discharge batteries have an important distinction from automotive batteries. They tolerate significantly more deep discharge cycles but can't produce as many amps. If you're just trickling a more or less steady amount of power into some electronics, you don't need massive amounts of cranking amps that an auto battery provide.

Solar PV and battery tech have definitely improved quite a bit since then, so were I now building these same installations, I might do something entirely different. But "back in the day" your advice of "buy another battery" was more or less exactly how we handled charge rate limitations.
No, it just signals that Kodi is unsuitable for the task at hand. Generalizing the capabilities of a decidedly non-mainstream application like Kodi to what is technically feasible is a bit daft.

No, not at all.

The reason it's expensive in the US is all regulatory, and because of the ever changing patchwork of utility rules that make it economical or not to attach your own generation to the grid.

Last I heard, roughly 30% of the cost of solar in the US is spent merely on customer acquisition. Because the only forms that survive are those that swoop in when there's a window of economic plausibility for solar to work for homeowners, before the utility in a particular small area changes their mind and buys off the regulators to make it cost infeasible for homeowners to generate.

There's a huge advantage to the grid of having generation be more local: more than half of energy costs are transmission and distribution, and these are costs that utilities can reliable charge a profit for, so they try to make these costs as high as possible. When customers install their own solar, this reduces the peak daytime need for T&D, and the grid is sized for peak usage. So everyone would be better off with far more local solar, except for the utility.

And to the extent it’s true it’s because they’ve been allowed to circumvent laws that were deliberately setup to limit the number of cabs on the street, and by flooding those streets with Ubers and Lyfts there’s a lot of research that shows that congestion and traffic has gotten much worse.

So even if a specific Uber/Lyft ride might be better, the residents of a city have a much worse overall experience.

And that’s without getting into how many of these drivers barely make ends meet, whereas driving a cab was a path to the middle class for millions of cab drivers for decades.
> Everyone is where they want to be, so of course they like working there.

This reminds me of the joke where the economist sees the $100 bill on the ground and says if it were real, someone would have grabbed it already. It assumes that the market is perfectly efficient when it is not. There are tons of reasons why someone would work at one job when they would prefer another job:

Maybe the local job market is poor, but the worker can't move.

Maybe their spouse has a medical condition that requires really good health insurance, and moving to another job would lose that coverage.

Maybe the worker has been job-hopping too much and has to stay at this job for another year or whatever.

etc., etc.

Point being, it's stupid to refrain from building new nuclear plants because they're "dangerous", because that forces the old plants to be operated far past their intended service life. Better to replace the rope before it breaks, so to speak.

In a rational world, those who believe atomic energy is inherently scary would be the first ones demanding that the old plants be replaced.

I support the post author's position completely. It's incredibly clear to me now after using social media for about a decade that it's not something healthy to participate in, and I shouldn't use it beyond a few really specific scenarios, like communicating with a business.

I've watched it destroy relationships, including some of mine, and turn people into psychopaths. When I meet someone new I can observe a pretty consistent correlation between how heavily they use the major social media platforms and how awful of a human being they are.

This type of innumeracy from nuclear advocates is rampant. It's not insane, you just put out a number that seems big, to you, and said "wow this must be impossible!"

Meanwhile, we deploy that all the time.

If nuclear advocates were better at numbers, maybe all the nuclear projects wouldn't be 2x-3x over budget and off schedule, and there would be more nuclear built.
> But oh, hey, you just bought a vacuum cleaner? I know what you would really like! MORE VACUUMS!

Amazon did literally this to me just a couple days ago.

I'd bought a vacuum cleaner on Amazon a week earlier, and, when doing an Amazon checkout of a cart with one item, it threw up a list of consumable items that I'd bought in the past, to possibly add to the order... including another one of those $120 upright vacuum cleaners.

(Maybe they have data that says this makes them more money, even though I'd guess it might hurt customer confidence in the site.)

> That works out to 16 hours / day $15 / hour * 365 days/year = $87600/year.*

True, but they also have to pay the staff who is monitoring the cars. Maybe 10 cars have one staff? For 250 cars, there should be a team of 25. Maybe they earn a year as much as one car saves? i.e. nearly 90k/year. So, that still works out profitable.
But you can't run the grid on 50% renewables without solving storage. It's just not possible: the grid has to run. Peak usage isn't in the middle of the day, it's around 6-8pm when people are home. In winter that's pitch black, in summer depending where you are there's still very little solar output, so you better hope the wind is blowing. And it is...mostly, but not on demand.

Germany's power grid has started to struggle because they're at 30+% solar capacity, but not reliability - the grid can't sustain losing large swathes of generation capacity suddenly because a cloud passed overhead, or if a region is overcast that day then you've got to make up that shortfall - which you can do so long as you have basically the same installed capacity of gas, coal and oil on standby where they can just turn on an extra-turbine or boiler on demand.

But if you want to actually decarbonize, then you need to solve that problem. Otherwise you end up with the perverse situation that increased renewable investment necessitates new fossil fuel power plants, because you still need to backstop the intermittent sources.

The NSW Australian power grid has this problem right now: the reality is that no one wants to invest in fossil fuel power plants. Great! You'd say. But the grid actually does need a new reliable generator and power price pressure is a big political issue. Getting reliable watt-hours onto the grid - not more intermittents - needs to happen. The catch-22 is people rightly don't want to subsidize more fossil fuels, but the available renewable options are being installed anyway - but they won't solve the actual availability problem we have (and in a country with bush fires it's a big one - 3 months of summer with overcast skies along the east coast from smoke means no one's solar panels were working well, and grid-interconnects have limited capacity).

The odds only sound equal/the details irrelevant because you are only looking at one outcome from the set. In reality, the email will resolve the probabilities to: (BB: 1/3 BG:2/3 GG:0/3} or {BB:0/3 BG:2/3 GG:1/3}. Although the BG values are the same, the rest of the probabilities are not. Therefore, the details are relevant.

I don't have a great explanation as to why that's intuitively true, but it is. I can try again if things are still confusing. But if so it would help to know if you understand the Monty Hall problem.
> Satellite terminals donated by Mr Musk's SpaceX, as well as the US government and private donors

To this day the number of terminals supposedly _donated_ by Musk, that means not paid for by State Dep, is unknown. We do have this tho https://www.washingtonpost.com/politics/2022/04/08/us-quietl...

As of October 2022 there were 18k Starlink terminals in Ukraine. At the time State Department (USAID) paid for ~2K units, Poland paid for >12K units - over half of all terminals came from one relatively poor EU country, curious how this is omitted by Telegram :)

December 2022 number rose to 22K. Apparently as of June 2023 there are >40K terminals in use, with USAID share rising to at least ~5K.

So the suggestion was untenable from the start.

Driving drunk should be penalized, even harshly. But people should have a chance at rehabilitation.

In a car dependent society/region, a permanent ban without an opportunity for reform is cruel and unusual punishment.

If self driving cars were 100% here right now, or if we had better public transportation, I think it’d be a different story.
The desktop application is the easiest way to get up and running on Mac or Windows where a VM is necessary. Of course you can still set up docker engine manually in a VM, but even then it doesn't offer the same level of integration, like host mounts, Rosetta on Mac. Desktop Linux is the only environment where the desktop app offers little benefit over just running the engine.
You know what is more controversial than letting robot cars drive around? Trying to make a new train line literally anywhere in the US.

You are better off buying a bunch of robot cars, tying them together with a rope, and starting a company to run hacker trains on city streets and charge money.

In fact, in SF, if the protestors were clever, they'd just get together tie a bunch of cars together and create their own train. What are they going to do, arrest you?
Imagine being a human driver who has to constantly change routes based on what the computer tells you, switch vehicles based on demand, and not make any mistakes. That sounds exhausting. You're also occupying a seat which could be used by a passenger.

A centrally-directed autonomous fleet of vehicles would be genuinely revolutionary for public transit, replacing everything from taxis to buses with a beautifully efficient system. I can't imagine not being excited by that.
Have any of these modern cost effective designs been built yet?

All of the third generation EPR projects being built in Europe have run hugely over budget. I really thought if anyone could build nuclear plants cost effectively it would have been France so it's really made me lose hope in nuclear power.
Not to mention anti-competitive behavior (which used to get you hauled in front of Congress).
Not sure why you are downvoted, other than you used numbers and real data which contradicts a nuclear narrative.

The EIA can be trusted with their reports on actual numbers. But their projections are absolutely embarrassing and underestimate solar deployments so much that they have completely discredited the entire enterprise of projections. The graphics showing how embarrassing they are all use the IEA numbers, but the EIA projections are just as bad

Its a popular design for SQL Data warehouses. I think almost all of them (snowflake, redshift, etc.) store cold data in S3 and hot data on local disk[1][2].

It works well if the data is stored as immutable files (i.e., A log structure merge tree) or is not index at all (classical columnstores). S3 doesn't provide an efficient way to update a file.

> I can't help but wonder how people making substantially less are managing, especially in the cities.

The way we manage is to make a lot out of (what you would probably consider to be) a little.

For reference, I live in a country with living costs comparable to the US, and my wife & I's combined annual income is about $30K USD, or around one-fifth of yours.

Our only vehicle is worth less than what you just paid your plumber, and my house's hot water system is coming up on 70 years old, but the thought of replacing it for nicety is out-of-the-question. If it blows up one day, then that's an emergency we'll wail about when it happens.

We pay a much smaller mortgage on a smaller house in a remoter location, we have no children, and that whole "vacations, sports teams, extra car for the wife, buying clothes, etc etc" mainstream paradigm is just ... not in the picture. We live differently, yet still, funnily enough (considering the salary disparity) fairly happily and comfortably. I want for little - assuming we put aside large existential things like 'end of your bloodline', which I try not to dwell upon.

Among many other things, I spent part of the past few years figuring out how to significantly reduce our food bills, basically by learning to purchase smart, cook well, and waste little. I equate that to somebody working extra-hard in the office to earn a salary raise.

I hope this gives some little context.
Not exactly. Most states, 0.08 or above is presumed guilty of DUI without any other impairment detected. You can still get a DUI with a BAC below 0.08 but it becomes a bit harder to convict since it becomes a function of the officer’s testimony and any physical tests administered before your arrest.
I think the state requires all the cars you are likely to drive to get whiskey plates. So it's possible the managers wife was the drunk driver.

I was reminded of another recent HN post (Suppose I wanted to kill a lot of pilots) https://news.ycombinator.com/item?id=37209309 after I read that comment. Whatever he's doing, do the exact opposite.

I have a family of 4 and I can feed the entire family for one meal for $10. For example, pasta ($2), sauce ($3), and a protein ($5). Rice ($1), protein ($5), and a veggie ($4). For breakfast, milk ($1) and cereal ($1).

On the other hand I took the family out to sushi yesterday which cost $100 and was admittedly more delicious than a home-cooked pasta meal.
My mother and her husband still use AOL email, which I thought was bad enough, I managed to persuade them some years ago that they didn't need to use the AOL portal to get at the internet.

I still haven't managed to persuade them to change ISP though, even though AOL removed themselves from the broadband ISP business in the UK, what, 20 years ago? And their connection had been bought and sold by different providers multiple times over those years, my stepfather is concerned that if he changes ISP then the email will no longer know how to find his house.

In the face of this sort of argument, I crumble. They could be paying less for a faster service with better support than they get now, but I guess that's never going to happen.
I think there was no realtime CC processing back then. In my last job I found artefacts like fax forms where they would write down collected credit card data (from online subscriptions) to be sent to their processor. To have at least _some_ safety they would just check [1] if the CC number is sound.

I think the comment was that if they buy a vacuum and don’t like it, they return it and buy a different one.
So if that happens 20% of the time, that next month has a much higher chance of buying “another vacuum” than the average month.

Also, I bought my parents a Roomba because I liked mine, so that can happen too.
> Capacity factor is an energy 101 concept, and evaluating energy based on overnight capital costs plus capacity factor misses out on the an exceptional number of crucial factors: lifetime of capital, O&M, cost of capital, and these days, dispatchability and time of delivery.

Oh, so like maybe throwing a quote about the cost of solar around without considering storage, capacity factor etc. you know - the $/kW numbers being cited above unsourced...might not be an honest way to talk about costs?

> dispatchability and time of delivery.

Seriously? You're going to argue that these aren't being fairly considered when I express skepticism that solar is "cheaper"?

> Then do a perpetual lease, or 999 year lease, or pay every year, or [...]

A perpetual or 99 year or 999 year lease is constructively a sale. Anything which is constructively a sale is banned.

Anything which is not constructively a sale will be rejected by the buyer, because they actually want to own the domain and not pay the danegeld to the squatter in perpetuity or be subject to extortionate price increases after they've committed to using the domain by publishing it in their advertising etc.

> How would you enforce a prohibition of leases?

If you offer to provide someone with use of a domain name in exchange for more money than you pay to the registrar to register it, you lose the domain name.

> Plus, the tricky bit here is there are lots of reasons for a domain owned by entity A to be used by entity B (companies might be related, might just be allowing a friend to use a domain, etc.)

You can use it all you want as long as you never pay them for it.

It doesn't matter if you can get around this with complicated corporate shenanigans because you can't sell that to arbitrary strangers who don't actually want to pay a premium for an unused domain.

If you advertise it in such a way that strangers understand you to be constructively selling the domain then they report you to the registry and you lose the domain, which then becomes unregistered and they can go register it for the ordinary nominal fee. If you don't advertise it in such a way that strangers understand you to be constructively selling the domain then you will have a much harder time finding anyone to pay you for it, as intended.

This isn't like drugs where both the buyer and seller want the transaction to happen. The seller wants the transaction to happen and the buyer wants the seller to go out of business and DIAF so the domain will be unregistered and they don't have to pay a shakedown tax for it. It's optimized for putting the sellers out of business because that's what the buyers want -- because the sellers provide no value to anybody and nobody but themselves wants them to exist.
It was not big oil that pushed the anti-nuclear campaign. It was environmentalists. And they're still active today, sometimes pushing for solar. Sometimes fighting solar and windmills to protect wildlife.

Now I'm sure some oil and gas companies decided to fund some of these groups because they saw these people could be useful, but that doesn't mean the movement was astroturfing.

China is not building nearly as much nuclear as they are solar, wind, and storage.

A reactor a year is a pathetic pace! 1GW/year! Even I f the US matched that, we will see most of our nuclear fleet age out before it was replaced.

For contrast, China is expected to be able to produce 6TWh/year of batteries in 2030, ~260 "gigafactories" worth:

https://source.benchmarkminerals.com/article/over-400-gigafa...

China's reluctance to invest as heavily in nuclear should be a clear sign that even with great competence at building nuclear, it's just not that attractive of a tech. It's barely functioning as a hedge, and is probably only being used for its side industries rather than as a serious power source.
