Let's do some more math

From the article, this new reactor is "estimated to cost more than $30 Billion." (Let's call it 30) & It generates 1,114 Mega Watts.

This article [1] says solar panels cost between $0.90 and $1.50 per watt. Let's go with $1/watt to keep the math easy, though I bet it's much cheaper by now, and especially at the scale we'll be buying them at.

So for $30 billion dollars, we can have 30 billion watts of solar, which is 30,000 mega watts, or 27x the amount of power of the new nuke. Obviously solar doesn't produce at night and it's seasonal.

So let's make it more useful.

I saw elsewhere in this thread to get an actual output number from solar you have to divide by 6 to account for night and seasonality. So that means to equal the 1,114 mega watts from the nuke, we need 6,6684 mega watts of solar. call it 7mW to keep the math easy.

So we use 7 billion dollars buying 7mW of solar.

We have a tidy $23 billion dollars left over to spend on storage.

This site [2] says grid scale storage costs something like $300/kWh. (I bet it's cheaper now, and cheaper at massive scale, but we'll go with that.)

So with our $23 billion left over dollars we go and buy 76.6 million kWh of storage (which is 76,666 MWh). So even when there is no sun coming in, our storage can maintain the 1,114 mega watts of output for something around 68 hours. That sounds like overkill, so it probably makes sense to spend more of the money on solar and less on storage, but you get the idea.

Also note for the same $30 billion dollars our solar + storage setup now has no running costs, no refuelling costs, no downtime due to refuelling and maintenance and no radioactive waste disposal problem.

Also note the $30 billion nuke plant is a single point of failure, and needs big lossy power transmission lines coming in/out to go useful places. I would be interested to see the numbers on how much of that 1,114 mW of nuke power winds up lost in transmission. The solar setup can be distributed all over, and can generate and store the power right where it's needed - on factories, houses, schools and where ever else needs power. Transmission loss of close to zero.

Nukes are awesome, but they're not even in the realm of making sense financially.
Year after year the price of solar and storage will go down again, then again, then again.

This is not a fair fight.

(Please point out any holes / problems in my math)

EDIT: as pointed out below the cost for grid scale storage is more like $500/kWh.
So for our $23 billion we can buy 46 million kWh of storage (46,000 mWh). So we can equal the nukes 1,114 mW output for about 41 hours. Still plenty

I think you are giving Russia too much credit. This is the same doctrine Russia used when invading Ukraine. I am sure all those agents and paid propagandists told their FSB and GRU superiors whatever they wanted to hear while pocketing most money for themself.

Putin is a gambler that has inherited lots of resources and wants to make high probability low risk bets. If he loses a round he goes double or nothing since he can do that a few times. Of course that potentially opens him up to ruinous catastrophic losses if confronted by a competent adversary. Then he will cry: "but my nukes....." and hopes everybody backs off.

As for propaganda I think they just throw everything at the wall and see what sticks. All is reactive post hoc information warfare unless there are meaningful consequences.

Btw to think that Russia would have taken any statement regarding NATO expansion seriously without it being written and ratified in a treaty is beyond comical.

Thanks for the longer writeup, I appreciate it. It'll take me some time to digest the concepts.
I read them differently.

>> I have a feeling that such a system would grind to a halt even with clever optimizations.

I took this to mean that they thought there was no falloff calculated at all. If there is, I don't see why substituting a different function, e.g. cube vs square, would be significantly more CPU-intensive.
So they simply launch rockets and then it rains down on their population with pollutants, I wonder what will happen after all that space junk will expire and it is time to decommission.

Idk who Mike Hearn is, and I'm always hesitant to call people out on HN for exactly this reason... but I think OP's airbag analogy was perfectly fair, since it was referring to the Apple bug where you could become root by simply clicking "okay" instead of entering a password. [0] It was comical in its simplicity.

But that said, overall I agree with Mike, in that Apple is clearly committed to security of their users. It's one of the main reasons I buy Apple hardware for my mobile, personal and work devices. Nobody is forcing them to put so much effort into that security, either - they do it largely by choice, and it distinguishes them from other vendors whose business models are inherently in conflict with their customers (I don't want to buy a phone from a company that derives most of its revenue from facilitating psychological warfare between advertisers and me.)

But I've always found this security to come with interesting tradeoffs. On the one hand, I'm pro-privacy and pro-user. But certain security objectives can't be achieved without reducing privacy or increasing restrictions on the user. Over the years I've come to appreciate this tradeoff, and I think Apple does a good job of balancing it. While I certainly don't feel like the device is "fully mine," I do feel like I'm getting some extra security in exchange for giving up some freedom to tinker.

Linux is of course very impressive and most Ethereum nodes run on Linux. But you can peg a machine to a specific version of Linux and never have to upgrade if you desire. Your machine is ultimately independent of other Linux machines. The key challenge with a blockchain is that you have to keep what amounts to a globally distributed and permissionless data center in sync with protocol upgrades and the cost of making a critical mistake can be in the billions of dollars. You have to account for not just technical vulnerabilities but game theory vulnerabilities.

The challenges are of course, entirely different in OS kernel land. All of them are impressive.
If I may recommend OsmAnd~ (https://f-droid.org/packages/net.osmand.plus/) on F-Droid if you're on Android (unlimited free maps), or Osmand+ (10 free maps) on iOS. It allows setting roads that you want to avoid generally.

It's a FOSS alternative to Google Maps, it uses OpenStreetMap for cartography data, in my experience it's pretty reliable and actually much better for certain use cases (like forest paths, in my region). It also has much better offline abilities.

I'm fully aware of Linux... It's also a very impressive open-source project. To elaborate, reason I consider Ethereum to be more impressive is the collaboration between maintainers and releases of different clients and client versions in different languages. This happens with different packages in Linux to some degree but on Ethereum it's a different ballgame because it's a live system, it's not like you can just let some users upgrade to beta versions and fix bugs as you go, everything has to work together perfectly with a system-wide change happening in under 12 seconds globally with billions of dollars on the line. There are testnets but no true analogue for mainnet. (Edit: chrisco255 below said it better)

Innovative Features in LuaJIT (2009)
> Maybe the trace amounts aren't enough to matter, but the consequences can be dire so they're cautious. Isn't this supposed to be about safety?

Safety should be about safe outcomes, not about maximising the number of warnings.

> They only added nuts to the product after you prohibited them from being conservative. And they're being atypically conservative because the "dangerous" label isn't applicable to most of their customers who they then don't have to worry about being deterred.

There's nothing atypical about it. They're finding the cheapest way to avoid liability and they genuinely don't care whether that means "being conservative" or poisoning their customers, and it's not going to result in good outcomes for the customers.

> Why is the company even involved in the process? They produce a new product and it initially gets a label that says it hasn't been tested, which will rightfully deter customers when most existing products don't have that label. The government performs its testing to check if it's harmful, prioritizing based on which new products are expected to be popular, and once published their results go on the label one way or the other.

Presumably you're going to campaign for the massive increase in taxation that would be necessary to enable the government to do testing comparable to what's currently done in any remotely reasonable timeframe? (And some kinds of testing simply can't be done fast - if you want to test for negative after-effects that may take years to show up, there's no way to make that not take years).

> As compared to the times when we've prohibited other substances and people all stopped using them immediately?

As opposed to market consensus on what was expected. And yeah, frankly, banning substances generally does reduce consumption; not to zero, but to significantly less than without the ban.
It's crazy reading the back and forth in these comments. It seems each side (pro-X11, pro-Wayland) always gets something wrong about the other. Makes it hard as an outsider to figure out what's true.

FWIW as a regular user of Linux desktops, fractional dpi scaling is very good on Wayland and sucks on X11. That's been the main thing driving me to want to use Wayland.

I've been toying with the idea of adding a tracing JIT to arc (https://news.ycombinator.com/item?id=38586832). I started off by trying to eliminate the call overhead compared to plain racket. I realized that I could generate optimal racket code for each loop by tracing hot spots at runtime.

I'm not quite sure how to go from "generating Racket code" to "generating actual native code", especially because I'd need to figure out how to interface with it via racket's FFI. It's an interesting question how fast a JIT for Racket could run. But for now, I'm more interested in the underlying techniques in LuaJIT.

> My problem with Xiaomi is the absolutely crazy data gathering. [...] On the other hand, all modern cars seem to be pretty bad at this.

Exactly. We'll hardly find one car, or for that matter any object with enough electronics on board which is both closed and connected, that doesn't use the technology to gather data on the user. Spying is a profitable business nobody in the industry can resist to.
Is this because of the data quality and difficulties with merging across CRSes or otherwise slightly differently aligned datasets?

I dabble in geospatial data for my work in air quality modelling, accuracy for me means being within approximately 10-50 meters. Even under those very loose constraints I find the data handed to me by clients is often not good enough. Incomplete AutoCad dxfs, PDFs, and dubious SHPs all make the work much harder than it needs to be.

Mr. Frakfurt would be proud.
For one no cryptocurrency is really designed to be used for actual payments. They all are deflationary by design so the future value of cyber bucks will be higher than today's value. If you spend cyber bucks today you're losing out on those future gains. It's irrational then to ever spend cyber bucks.

Unless cyber bucks are accepted to pay taxes in your jurisdiction (they're not) they need to be converted to a currency that is accepted. Thanks to the deflationary nature of cyber bucks, their conversion rates fluctuate wildly and constantly. The conversion rate can even change while waiting for a transaction to complete.

To boot every transaction is caveat emptor, there's no protections against fraud or even simple errors. Access to a wallet's private keys (even if they're not your keys) confers access to the wallet and all of its cyber bucks.

If the goal of cryptocurrency is to replace fiat currency transactions it's like the worst possible design for the task.
Anytime I try to organize my budget in a meaningful way through an app, spreadsheet, or dashboard, I end up departing away from it after the initial rush of enthusiasm wears off I have for using it.

This might not be the best system, but it works for me. I simply take 70% of my income and deposit it in another account with a seperate bank (it's like a vault, i never really check on this account ~maybe once a month) as soon as my paycheck clears and then just make sure to make do with the other 30%, which includes one-off discrete purchases, emergencies, etc.

I have no visibility on my purchases. I am sure I would be alarmed at my monthly expenses for specific things, but on net, I think I am on the lower end of frugality.
