Aha ok, but if I am understanding this right, the future can change the past of this graph, right? Like our hypothetical user who first appeared in 2012 and last posted in 2016 - right now they appear in the 2016 red line but if they showed up again today and you made the graph again next year, they wouldn't be in the 2016 red line anymore. Or put another way and one that you can try: What happens if you cut off the data at 2022, 2021, 2020, 2019, 2018, etc and plotted those graphs? You'd see a different (rather than merely truncated) graph, no? Maybe even a different trend. So if my understanding is right, this is a pretty wiggly metric. The history of something you want to use as a historical trend line should not change as you append more data.
Yeah; and we have plenty of other general purpose databases which can run laps around postgres and sqlite.

There's plenty of optimisations postgres and friends leave on the table. Like, the postgres client driver could precompile queries and do query planning on behalf of the database. It would introduce some complexity, because the database would need to send information about the schema and layout at startup (and any time it changed). But that would remove a lot of unnecessary, repeated makework from the database process itself. Application servers are much easier to scale than database servers. And application servers could much more easily cache the query plan.

Weirdly, I think part of the problem is economic. I think there's a lot of very smart people around with the skills to dramatically improve the performance of databases like postgresql. Across the whole economy, it would be way cheaper to pay them to optimize the code than needing companies everywhere to rent and run additional database servers. But it might not be worth it for any individual company to fund the work themselves. Without coordination (ie, opensource funding), there's not enough money to hire performance engineers, and the work just doesn't happen.

> China has the same vast distances across low density areas as the USA does so you can't blame it on Europe and Japan being higher density.

There is only one HSR line that has been built in the western half of China, a line from Lanzhou to Urumuqi. It is pretty devoid of rails of any kind on that side. It was a huge technical achievement when they were able to build just a normal rail to Lhasa.
I would recommend learning only one new tool at a time, rather than a suite of tools. It will be less onerous and scary learning the safety practices, and you will be far less likely to slip up. (Plus, it's more affordable to only buy a new tool as you need it.)

Also, some tools are a whole lot safer than others. Tools that carry a risk of flinging your project (such as table saws and lathes) are risky, but a lot of other tools (such as jig saws and tracks saws) are very unlikely to cause serious injury.

And, of course, you can do without power tools altogether. People have used hand tools exclusively for the vast majority of the history of woodworking, and many people today still primarily use hand tools because they are more precise, safer, and often easier to use (albeit slower).

Probably so the auto drivers don't get their skull cracked by a tire iron.

Auto Rickshaw unions are VERY politically powerful. One former member has become Chief Minister (Eknath Shinde) and have played a major role in swinging elections in Delhi (INC to AAP), Karnataka (BJP to INC), and Telangana (BRS to INC).

E-Rickshaws are excluded from these unions, as most e-rickshaw drivers tend to be migrant workers from poorer areas like Bihar or Eastern UP while Auto Rickshaw drivers tend to be locals of the state.

By advertising as being petrol, that means they are part of the Auto Rickshaw unions, so you as an e-rickshaw driver or police officer know not to mess with them.

Can.. CAN???

This is the sort of magical thinking that the pro nuclear crowed cant come to terms with. Yes you can, why didn't you did this hole in the ground in 1980 when the first reactor went on line... Looking for a site to dig at next year does not solve the 40 years of waste (public electric, Canada has waste going back to the 50's) sitting on the ground outside at every nuclear site out side the baltic. (they dug a hole, and guess what its filling up pretty fast cause they built more stuff after they started digging).

Who pays to clean all this up? Who is going to foot the bill for the hole? who is going to fund security for it for the rest of time. Show me that math before we build one more plant. Dig the the hole. DO IT don't TELL ME ABOUT IT.

SEE: Every project in the world that was going to do it, France, USA, USSR, Japan, Canada... and one working hole in Finland that will fill up in half the expected time.

>> It's currently not economically viable to reprocess it because uranium is so cheap, but having it available for possible future needs would be nice.

Dig it up, and then leave a mess for someone else to clean is no different than the economics of coal, it's just on a smaller scale. And thank god cause uranium has a half life.

>> You are comparing apple to orange: the above was a tiny module. Nuclear "waste" from reactors is stored in cement cylinders that weight tonnes.

>>> The nation's spent nuclear fuel is initially stored in steel-lined concrete pools surrounded by water. It's later removed from the pools and placed into dry storage casks that are made of steel and concrete or other materials used for protective shielding.

From: https://www.energy.gov/ne/articles/5-fast-facts-about-spent-...

The waste isnt embedded in cement, Its in a cement container with a cement lid. They used to use (and may still be made by a company that makes) septic tanks. Your nuclear waste has the same protective storage as a rural house puts its shit. The only reason it goes in this sort of housing. Because it makes it hard to casually mess something up (see every pre 1970's nuclear accident, and there are LOTS OF THEM, including at the same site as the next point).

You mean this reactor that Canada shut down:

This was vital, maybe for the public good sure. And leaking heavy water. In the grand scheme of things not THAT bad, but should not be happening... was this a systemic failure or a true accident? The reality was that the the economics to run it safely weren't there.

Insightful quote:

> The fundamental question came down to economics. Almost a societal economic structure question. The CPSC says table saws result in about $4B in damage annually. The market for table saws is about $200-400M. This is a product that does almost 10x in damage as the market size. There's a disconnect—these costs are borne by individuals, the medical system, workers comp—and not paid by the power tools company. Because of that, there’s not that much incentive to improve the safety of these tools. Societally if there was an opportunity to spend $5 to save $10, we’d want to do that. But in this chain there's a break in people that can make those changes and people that are affected, so it’s not done.

> My understanding is that solar and wind are cheaper than nuclear even when accounting for storage.

In Ontario nuclear costs 10¢/kWh while wind costs 15¢ and solar 50¢ (Table 2):

And when wind goes to zero at night, then (natural/methane) gas generators are often spun up.

Which wind and solar also have. You may be able to extract some metals from solar panels, but turbine blades are not (AFAICT) recyclable.

Right in the article, it says most patents are now expired and for the final key patent that expires in 2033, the owner -- SawStop's corp parent -- has offered to donate it to the public if this rule passes.

edit: if you believe different, please share. But per this article, patents do not seem to be a reason to avoid this tech. And the SawStop v1 was introduced in 2004, so it stands to reason we can now produce patent-free equivalent tech to the 2004 machine.

Do you really have to recharge every couple hours? I use AirPods and find that they last for several (3?) hours when the mic is being used simultaneous with the speaker (zoom/phone), but much longer (5?) when just being used for playback. For me, this is plenty — especially because I don't use both ears at once. There's always way more than enough time to charge one while using the other.

What wireless 'buds have only 2 hours of battery life when for just playback?
That 60-80% number is a lie.

They are comparing 3 costs for different power sources (construction, fuel, O&M) but decommissioning for example isn’t included and it’s far high for nuclear than the others.

Risk is another. Several nuclear reactors including Three Mile Island suffered catastrophic failure and not only failed to produce power but added explosive cleanup costs.

> For example, you claim a need for "seasonal" storage out of nowhere, but do not consider the obvious (to the HN audince at least) idea of overcapacity such that there's enough generation at the seasonal minimum to cover needs, and oversupply the rest of the year.

No amount of overcapacity will make solar panels produce electricity at night. You'll at least need diurnal storage, no amount of overproduction will help solar power offset the day and night cycle. Overproduction is also not a silver bullet: solar production during cloudy days and wind production during still winds are often under 10% of average output. You'd need a massive amount of overproduction in order to avoid building large amounts of storage.

As for your battery production predictions, these seem very far-fetched given the history of lithium ion battery production. Bear in mind that production capacity is a different figure than actual production. Production capacity is what factories theoretically could make if given unlimited input materials. But that's not what matters, what matters is actual production figures - how much battery capacity was actually built.

2023 saw 680 GWh of lithium ion batteries produced worldwide: https://autovista24.autovistagroup.com/news/which-manufactur....

2021 this figure was 476 GWh: https://interactanalysis.com/insight/lithium-ion-battery-mar....

Will we actually see 7.9 TWh of batteries produced annually by the end of 2025? The growth over the last two years was only about 200 GWh of capacity, so seeing over 7,000 GWh of production increase over the next two years seems a bit far fetched.
Something doesn't match here!

First,

> The Japanese and Germans are not known for their wildly emotional thinking

Okay. But the French, uh, sorry, but IMHO, the French are "known for their wildly emotional thinking", e.g., French music, painting, cooking, ballet, wines, architecture, perfume, women's fashions?

Second, it's the French who have done especially well with nuclear power!

Doesn't match!

How? Why? How could that be?

Uh, a guess: From the old French kings to Napoleon and DeGaulle, the French have had, have put up with, relatively strong, maybe autocratic, governments.

So, the difference might be that the French have autocratic governments. Uh, right, Japan and Germany have had governments that were even more autocratic, that is, until the end of WWII. Since then, maybe France has been the more autocratic.

So, why might autocracy help in being successful with nuclear power and, in the US, our democracy has fumbled, dropped, tripped over, kicked, fell over the ball?

Obvious suspicion: The US has had (A) too many politicians, lawyers, and news journalists causing trouble just because they like causing trouble and (B) too little strong leadership, e.g., autocracies, able to make the decisions mostly via the science and engineering to get the real work done without being blocked, attacked, misled, dragged around, kicked, etc. by (A).

Just a guess, guys!

The evidence is sitting there: Emotional France has done well. Rational Japan and Germany, not so good. US, with plenty of science and engineering smarts, fell over the ball, might have been cheaper to generate the energy just by burning dollar bills in a coal plant! WHY??? Got a better explanation?

The big problem is that nobody wants yet another platform-specific UI framework. Even Microsoft is using electron (or something like it) to build Microsoft Teams.

If you build a cross-platform UI framework, it'll probably end up looking a bit ugly and custom on every platform (eg Java Swing). Making a cross-platform UI toolkit that looks native everywhere is an insane amount of work, because different platforms have very different UI toolkits, with different built-in components and different platform conventions. This problem becomes 10x harder if you want to make it work on mobile as well.

Some people try anyway - and bless their cotton socks. But electron (and arguably Qt) are the closest we've got. And even then, most electron apps seem to be full of custom components.

Decommissioning is not a major cost factor, amounting to a single digit percentage of the total cost. 400 million dollars may be a lot in nominal terms, but compared to nuclear plant costing tens of billions it's not a major factor [1]. Furthermore, in the US nuclear power plant operators are required to deposit into a fund to pay for future decommissioning [2]. It's factored into the cost, contrary to your assertions otherwise.

I'm in the UK, I used a tablesaw professionally for some years, often in very basic circumstances. I have never ever come close to an accident with a tablesaw. The reason:

1) UK tablesaws all come with a top-guard and a riving-knife fitted. The riving knife stops the timber from closing on the back of the blade, causing a kick back. In many designs it also holds the top guard up.

2) During my apprenticeship training there was a mandatory table saw course. We were taught how to set the guards and safely use the machine.

3) a riving knife based guard gets in the way of cutting grooves and rebates. If you take it off to do this then you replace it with a guard or jig to keep it safe. Then you put it straight back on.

4) I sometimes watch American 'makers' on YouTube and they terrify me with their working practice. My hands never went closer than the edge of the saw table. I used push sticks and jigs to handle everything close to the blade

5) I have never seen a sawstop over here, and it looks like a stupid hitech solution to a problem better solved by guards.
> It's whether the research should be done/allowed at all if it could harm a particular political ideology.

I think we can agree that it would not be responsible. So where does the line get drawn? I don't know--I'm not going to draw it.

Vogtle is $170-$180/MWh. https://www.powermag.com/blog/plant-vogtle-not-a-star-but-a-...

New solar is on average $40/MWh: https://emp.lbl.gov/sites/default/files/utility_scale_solar_...

Back in 2022 when prices were higher, NREL put batteries at $482/kWh:

https://www.nrel.gov/docs/fy23osti/85332.pdf

That's $87/MWh for storage, backing out the battery lifetime and round trip efficiency from the same report.

So depending on the time usage of electricity, the average solar+battery installation will have an averaging of $40/MWh and $127/Mwh electricity.

That's using old prices. It's cheaper today, and will get cheaper in the future.
This is a power, not capacity though. Real power plants could produce that many GWs continiously, but battery storage can only do for a limited time.

I could not find GWh figures for that particular install, but other grid-scale battery storage systems only has 1-2 hours of capacity, a far cry from real power plants.
