At $0.8/gross watt and 25% capacity, solar breaks even at around 20 years at 2c/kWh. At 3c/kWh you can also cover interest and upkeep and make a net profit. Prices are falling double digit percentages every year. The story is similar for wind, although prices are no longer falling rapidly.

2-3c/kWh for nuclear takes care of your variable costs of operation. You will never pay back the building costs at 3-4c/kWh.

The financial payback time for renewables is shorter than the build time for the nuclear plant, whereas the nuclear plant will need subsidy to stay on after 20 years or so.

Ie. if I have $10 billion right now, I can spend it on nuclear. In 15-20 years I will have ~0.8-1GW of net capacity that will begin to produce energy at a marginal cost of 3 to 4 cents per kWh and nothing in the bank.

Or I can spend it on ~4GW net of solar. In 20 years I will have my original money back, a modest profit, and a mostly worn out system that will conservatively produce ~1-2GW net at a marginal cost of around 1c/kWh for another ten years. Additionally industry trends imply that half of my money will buy me 6-8GW net of capacity in the same space if I simply replace the panels with 30-40% efficient ones (as over half of the current costs are land, permiting, and frame).

The outlook is not quite so compelling for wind, or high latitudes, but it still blows nuclear out of the water.

The story also looks a little better for nuclear if you're anticipating green hydrogen or ammonia costs to be prohibitively high or you decide to bulldoze the fossil fuel plants rather than using them as part of a chemical storage system. Additionally if you are anticipating energy growth nuclear looks good in the short term (but after 60 years we're basically back at square one arguing about thermal pollution rather than CO2)
Yup, gonna be a rough night for all involved.

Why exactly are people staking then? How are they being rewarded for slashing risk? Who do you think gets the gas fees? You know ETH2 still has them, right?

> the stakers aren't paid out by future stakers, they are paid out by diluting everyone and via fees for usage.

Again, you’re absolutely misinformed here, but aren’t crypto maximalists supposed to be all about how bad inflation in fiat is? Or is that old news?

Armageddon (Nuclear Armageddon)
Nobody needs to run a local node because there are proxies like Cloudflare. You've probably "used" IPFS without knowing it.

That said, visitors/people browsing the web can run a local node. A browser add-on overwrites proxy URLs to point at your local node.

Another way to think of it is that a local node is essentially your own personal CDN edge cache. Cloudflare's closest edge cache might be 20ms away. But if you run your own, it's just 0.2ms away!

The web browsing experience, while running a local node, is virtually unchanged. You may simply notice some speed ups loading content which makes heavy use of IPFS (which I regularly do, since most DApps use IPFS extensively).

> that traditional mathematical convention requires single glyph variable names due to the unfortunate decision to save paper by denoting the product by juxtaposition.

It's not to save paper or because of the product. You don't know the solution to the problem you are working on from the beginning and most of the time is spent writing and writing and writing in a scratchpad trying to solve what you need. Anything longer than a single glyph for variables would be too tedious so everyone evolved to use single letters. And then the papers are written with the same convention since it's natural. You have variable names though with the use of subscripts with the added benefits that it can be (and is) used to elegantly group relevant variables together giving you some sort of abstraction

I once wrote a comment about it here on HN - language in maths is not a programming language used to tell a computer how to go from A to B, but a natural language used to talk about maths between peers. Every natural language have idioms, inconsistences and other quirks. Polish will not change for you so it's easier for you to learn it, it will change in the way that let's polish people communicate better with each other which also include a lot of historical and cultural happenstances. Same with maths

There are attempts like Esperanto and other artificial languages like that and I think any attempts at 'codification' of maths to use some programming language has the same chance of success of wide adoption

A lot of people still have legacy Yubikeys floating around, and these are replayable. What you need now is something like the Google Titan FIDO2 key or one of the Yubikey FIDO2 keys. Transitioning an entire company to these, getting everyone to self-enroll, and then removing the ability to use all the less safe options across the employee base, contractors, etc is not cheap nor easy, and of course requires a massive amount of retraining. It's not as trivial as just buying them, sadly.
And even when you do get it setup you end up having to make all sorts of exceptions for various people who can’t be told “no”.

The thing is, most "crypto haters" on HN are just regretful no-coiners. Crypto is exactly the type of thing you would except HN to love, it ticks the box in so many ways, except for the one where... They forgot to buy some and are forever resentful.

I honestly struggle to believe this group of people truly care that much about crypto's effects on the environment; from the people I've spoken about this with personally, they always come across as hyperbolic and dishonest.

To some degree I believe it is their brain subconsciously trying to justify their hared because they were "left out," the same way some people, for example, irrationally hate The Avengers because they never saw it and got sick of hearing people talk so much about it around its release. Each reminder of being left out burns you just that little bit more, and it's hard to be objective and come around to something once you feel that way about it.

I'm not surprised this "ya but, crypto still bad" comment is the top comment here on HN. It's pretty funny to me.
Transactions are not finalized for 30-60 days at banks and even longer for payment cards. This is why you can charge-back. 'Time to usable funds' and finality are not the same thing. And no, Eth2 reaches finality in 12 seconds.

Note I'm comparing digital collectibles with provenance determined by WotC servers to digital collectibles issued on the blockchain, i.e. NFTs. I'm suggesting the latter could prove to be more valuable than the former. I am not comparing digital collectibles to physical collectibles.

>>With the way NFTs work, the blockchain version of one would be an infinitely copyable file that just happens to have a scoreboard somewhere that says that only one person can "own" it in some very specific sense.

There are already NFTs worth tens and in some cases hundreds of thousands of dollars of ETH (see CryptoPunks NFTs) so we know people are willing to pay for something where the image is copyable, but the original can still be authenticated.

In the case of the physical copies, people can easily photocopy them or share their images digitally, yet the verifiable original still retains its value. I don't believe inability to copy the image associated with a physical or digital collectible is what imparts the collectible with value.

For the most part they already do what you suggest.

Companies are required to have plans for save disposal. The problem is currently if you have a total failure, you are not required to pay for removal. This could be added as a law and then it would just be part of the insurance package.

Also, most actual space junk in LEO are government sats or parts of rockets that launched government sats.

Commercial stuff is mostly in GEO and there you also have a disposal problem but its quite a different problem then LEO.

This seems to be a very bad approach. Amount of launch does not have much to do with how much debris exists.

You would need to modify the execve system call (or equivalent non-Linux OS's) to take in the 4th json arg for the shell to pass when it exec's the new process. And then of course modify the OS kernel to parse/deal with it. But in reality, since you can't break the ABI like that for all existing software, it would end up being execve_2 or something and you'd have to both convince everyone else it's worth using, and deal with the inevitable incompatibilities when not everyone does. Not impossible perhaps, but certainly an uphill battle.

>You could get shot down 50 times in a row

You're treating it here like this is no issue, but do you actually know anyone that can take that many rejections in a row and not have it impact their mental state? Even if you know it's not a judgement on you etc. etc., it is hard for any human to continue in the face of so many rejections. It's not just about dating -- successful entrepreneurs are often those people that can take rejection after rejection and continue going. But it's very hard and very rare.

In general I am on the same side -- you can get much better success approaching in real life vs. on the apps. But what the apps abstract away is that rejection which you feel very intimately when in person.

The open source API Gateway project, APISIX, was open sourced and donated to Apache Software Foundation by API7.ai[1] in 2019, many people asked why not use Kong, AWS or other products? The main reason was Kong relies on PostgreSQL and AWS Gateway is vendor locked, now Kong has supported the DB less deployment mode, Apache APISIX also supports this way, this mode is easy to maintain with GitOps.

The age difference, rather. (Measured not in years but in percents. 15% max is a good rule of thumb.)
As someone who is 6' 4", I agree. Not that I'm complaining, but given the choice to pick my height, I'd opt for 6' 2". For pretty much all the reasons you mentioned but also because the world is built for people closer to average height. Think kitchen counters, plane/bus seats, stairwell ceiling clearance, etc. I'm relatively young but have back problems that I partially attribute to my height.
In the context of "turn the most gas and coal plants off per dollar ASAP", I think 80% is pretty reasonable. Especially when you include things like plants that were paid for but never opened and various safety shutdowns.

Similarly 25-30% for solar and 60% for wind with them being anticorrelated enough that you can call an equal mix ~40% over all.

The other benefit is solar+wind incentivises storage development in a way that nuclear does not. Cost-wise, for many applications it's optimal to overbuild by a factor of 2 or 3 just to get energy in the sides of the energy curve. This results in energy that has been paid for, and can be turned on or off in milliseconds but has no value at 11am.

Many storage technologies become viable at $10-20/MWh that need further development to be viable at higher price.
