1) it takes co2 from the air and water to produce propane hydrocarbons (mostly theory with some promising lab results)

2) not quite. Well, it is a form of carbon capture, but with the intent of releasing again soon.

3) 4% co2 is everywhere (open a window and turn on a fan and you have almost infinite). Water is everywhere humans are. I think it is a lot more an engineering problem than a feasibility problem

A proper taskbar. Needing to install a third party extension to achieve the type of taskbar that has been expected from desktop OSes for the past 20 years is lunacy.

In Australia, I'm very optimistic about Suncable[1], I just wish they were able to move faster (I do get that national coordination is slow, and that it's an enormous project).

Also did a back-of-the-envelope calculation the other day. It would cost roughly $175 billion to add solar panels and a battery to every residential dwelling in Australia (commercially priced and assuming available supply). That's a ton of money, but there are also individual people in the world that could afford that bill and change Australia, and the global power network, forever.

Building AI-powered SWE tools: Essential commercial considerations for founders
> All the more reason to set strict deadlines on all API calls!

I've seen this backfire in production though. E.g. suppose there was a 5 sec limit on an API call, but (perhaps unintentionally) that call was proportional to underlying data volumes or load. So, over time, that call time slowly creeps up. Then it gets to the 5 sec limit, and the call consistently times out. But some client process retries on failure. So, if there was no time limit, the call would complete in, say, 5.2 seconds. But now the call times out every time, so the client just continually retries. Even if the client does exponential backoff, the server is doing a ton of work (and you're getting charged a ton for lambda time), but the client never gets the data they need.

Better in my opinion to set alerts first.
Ownership of the private key proves exactly ownership of the private key. Sometimes that means you're trusted to make certain statements (e.g. about value transfers in the case of cryptocurrencies); other times that means you can identify yourself in some scheme.

What you definitely can't do with that by itself is prove that you are the author of a message signed with a given key, because anybody else could just sign the same original message with their key, and then send a follow-up message using that same key. How'd anyone know which message, and by extension which key, is the real one?

You need some extra infrastructure to pseudonymously prove authorship, e.g. a secure timestamping service.

Coal bounced back from an economic downturn in 2023. The previous peak was in 2014 at 44,858 TWh which was almost matched in 2022 and then slightly exceeded in 2023. Hardly significant growth.

It’s likely somewhere between 2023 and 2026 will be the all time peak but it’s only really dependent on the economy in the short term. Long term coal is clearly dying and looking at China’s energy policies it’s going to start dying quickly.

Until they've made a billion dollars I'd assume the situation is not that rosy. It is easy enough to do a cool science experiment for $65 million. That being said, I applaud anyone achieving any result when it comes to energy.

My first test for Chinese success is "would this have been legal in the US?". I'm not sure who regulates tokamaks but I assume they have a similar risk profile to nuclear reactors (nuclear process releases a vast amount of energy in a tiny space) and so it would be normal if building one commercially was prohibited.

Technically you're right (Bitcoin's UTXO and script model implements a general and quite flexible mechanism); practically, almost all transactions use that mechanism to implement the regular old "account a (a set of public/private keypairs) transfers money to account b (holder(s) of other keypairs)" model.

Well, mine is propane, and propane is substantially less energetic than gasoline, and is also subject to delivery fees.

The issue you really run into is that, even at idle, the generator burns a fixed amount of propane. The minimum is about 2 gallons per hour. Which is roughly $6

So you can imagine that, for 3 days of usage, $500 provides a strong incentive to seek out alternative sources of power.

We run about $1200 a year in propane costs for the generator, estimated.

Generally the answer is "we bought this product 12 years ago and it doesn't have an ARM version". Or variants like "We can't retire this set of systems which is still running the binary we blessed in this other contract".

It's true that no one writing "fairly standard software" is freaking out over the inability to work on a platform without AVX-VNNI, or deals with lockless algorithms that can't be made feasibly correct with only acquire/release memory ordering semantics. But that's not really where the friction is.
There was no reason to think that vision-based self-driving wasn't possible - many vehicles today have varying forms of self driving abilities that use only vision and have for some time now.

But Musk regularly made wild claims about how they already had it working and it was going to be released within the next two years. He convinced a lot of people to pay a premium for the FSD beta that only now is capable of driving along a well maintained city street on a dry, sunny day.

Tesla certainly wasn't the only one working on vision-based driving assistance technologies, nor the only to succeed at various aspects of it.

Musk loves to speak about himself and his work as if he is some pariah suffering at the hands of the establishment, but nothing could be further from the truth. The hard working folks at Tesla have moved mountains and would have done so with or without his endless tweet storms. The rest of the industry has pressed on too, and as the technology improved, they too would have moved closer towards full FSD if Tesla didn't get there first.

Elon Musk's greatest trick is convincing millions of people that he is a genius that is responsible for all the technological success that his thousands of employees have worked hard for.

> Grid scale battery storage has recently become economic in lots of cases and is ramping up quickly

Being economic and being cheapest are worlds apart.

Solar or wind + utility-scale storage come in at 46 to 102 and 42 to 114 $/MWh, respectively, in terms of LCOE [1]. That does not include grid firming costs [2], which could raise the upper end of those figures to $120 or more, and is based on current storage prices; if everyone tries to build at once, it rises. (On the other hand, there are further economies of scale to be realised.)

Fission clocks in around 141 to 221 $/MWh, which is why we aren’t building it, but $31 at the margin, which is why closing working plants is stupid. SMR focus on lowering capital costs through economies of scale. Fusion by reducing compliance costs. In all likelihood, the solution is fusion SMRs baseloading solar, wind and geothermal energy with peaker industrial processes running during the day. (Hydro can come too.)

that looks a heck of a lot like a rebranded Trinitron. (I bought a super nice Sony Trinitron from BestBuy in fall 1994 to get a better screen for a second hand Sparcstation 1+ i had.)
This could be that you just noticed it? Panasonic plasma cells brightness is controlled by PWM off a 600 Hz carrier (it's even proudly advertised as "600 Hz!" on the TV box and stickers). While the number is quite big and stands out nicely against "240 Hz" advertised as refresh rate for the competing LCD TVs, it did not provide many different brightness levels per pixel (keep in mind that it's divided by 60 Hz or higher frame refresh) so those TVs were running temporal stochastic dithering to create more levels. If you looked closely at a new plasma TV screen it was very noisy with random pixels firing up at high frequency.

This is very well written. I enjoy the style of tbe prose.

Incidentally, I agree with the approach: I too write to reveal my ignorance and incongruencies. And then I work to learn, revise and improve my understanding. Writing is a humbling process.
It’s refreshing in its stripped down aesthetic, but I missed where it tells potential users what Cognate is especially good at, who it’s for, why it was developed, or why I should devote the time and effort to learning it?

Rather, it makes cute remarks about how little it cares for how math works…well if it doesn’t care, why reinvent basic mathematical syntax? It goes out of its way to be confusing, and then flips you off for asking why. I must be missing the larger point of this project.
The heat! Many plasma displays had a faint heat you would feel on your face if you were near that I found uncomfortable. I am not sure if others felt the same.

There are inverters with a power outlet that can be used in case of a grid outage. Supplying your whole home with power when the grid goes down is possible too with the right hardware.
I already addressed that situation.

In this situation, ownership of the private key is proof you could have written the message (and no one else could have, unless the key was compromised).

Which from the point of de-anonymizing yourself intentionally is more than good enough.

If you copy and pasted the original from someone else, that doesn’t matter in this situation no? You still ‘reposted’ it as your own.

Since the scenario is someone going after the authors of a post. Or someone who posted showing they were the ones who did the post.

Any timestamps would be provided by the forum the posts are in.

During the early Covid period there was a general sense that “the rules don’t apply” or “the rules are insufficient” for this crisis and therefore can be safely ignored when they conflict with Covid counter-measures. Even those in authority were breaking some laws to respond to it. In addition any action that could be perceived as “combating Covid” was seen as an automatic good. Combine all that with the extreme fear and uncertainty and you have the perfect environment to make a stupid move. The IA should just admit the “emergency library” was a mistake, move on and stop wasting money and risking the entire project on this.
Funny. It used to be if you received that sort of response, you might imagine the author being pressed for time and giving a sort of prewritten/canned copy response.

I guess LLMs have removed some of the tedium from the process while making it more tedious for the recipient. That's annoying.
Eh. Its a tool, just like a calculator, a computer or a drug. Just like everything else that has potency, you can use it well or poorly.

I got some help from ChatGPT while writing a recent paper. At one point while writing, I couldn't find a straightforward way to express myself. I was stuck - and then every attempt at writing the same paragraph came out worse than the last. Eventually I gave my draft to chatgpt and asked it to come up with a few suggestions on how to express my ideas more clearly. That really helped. I adapted some of its writing and ended up with a better final result.

I'm not sure if anything chatgpt wrote is in the final paper. But I really appreciated the LLM assistance to help me express myself.

I'm sure there's a lot of much more egregious examples where chatgpt wholesale wrote large sections of some papers.

But its really not the tool that's at fault. Its how the tool is being used. And we simply don't have social norms around that yet, because figuring out norms takes time.

The calculator was the same. When is a calculator acceptable in a classroom? In an exam? Our teachers at the time justified "no calculator" policies by saying "You won't have a calculator in your pocket when you're going through life!". And, well, that turned out to be very wrong.

I knew some acquaintances back in the day (late 80s/early 90s) who had a company selling X servers. It wasn't a big operation (maybe half a dozen people total) and it worked out of a small office in the industrial section of Ft. Lauderdale (a fairly seedy looking neighborhood to say the least). But they made a decent living for maybe a decade or so and had some fairly big customers.

Depends on your local grid reliability.

It would have been foolish to have a whole house generator where (and when) I lived before I moved where I am. Where I live now, utility power is less than three nines, and some years doesn't quite make it to two.

Solar without storage usually is grid tied, but even if it runs isolated, it doesn't help overnight. Batteries for a multiday outage are still quite expensive compared to a generator.

A whole house battery would be nice though, at least some of the systems can switch power quick enough that I wouldn't need UPSes at all my computers, and the battery maintenance that requires (of course, the large system would probanly require maintenance)
Yes, but the public key does not actually, contrary to its name, have to be known to the entire world.

As the article shows, in many signature primitives it's necessary to assume it is (or at least visible to everybody able to view plaintext message-signature pairs signed by the corresponding private key), but primitives that don't have this property might be usable as native (and by extension more efficient) designated verifier signature schemes.
Memory is a weird thing.

He's mocked because he has lied about it constantly for a decade.

In 2016 Tesla claimed "as of today, all Tesla vehicles produced in our factory – including Model 3 – will have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver." That was a lie: https://www.tesla.com/blog/all-tesla-cars-being-produced-now...

They faked the full self-driving demo video: https://www.motortrend.com/news/tesla-full-self-driving-vide...

Musk promised 1 million Tesla robotaxis on the road by the end of 2020. That was a lie: https://www.thedrive.com/news/38129/elon-musk-promised-1-mil...

Musk is plainly not interested in credibility. He'll keep lying for as long as the lies keep working. True believers like Whole Mars Catalog will always find a way to rationalize the lies to themselves.

This seems to be overlooking the largest factor, which is that "renewables are cheaper!" has been a claim in the discourse for something like 20+ years and was a lie for most of that time. It is taking people a while to come around to the idea that this time the claim is serious.

There are obvious failures from pushing renewables - Germany springing to mind, or any number of solar subsidies that proved uneconomic - and it was completely reasonable to wait for some demonstrated successes.
I don't believe I made any implications about how the world should act, or whether peace is possible. I made a point about a major motivating factor. That isn't to say it's the only one.
BTW, what is the new word to use when one literally means literally?
> As more and more intermittent renewables get pushed onto grids, they become more reliable

This is called grid firming, and it’s massively expensive.
There have been some great responses that cover the gist of it, but to add a couple more mundane specifics:

- Build up the thinnest abstraction that lets you express a solution in the problem domain.

- Allow the API user to express their intent, and not be focused on mechanics they don't need to understand to get the job done.

- Focus on getting the interfaces right before the implementation is perfect.

- A clean interface will allow you to make drastic changes to the implementation without the API consumer becoming aware.
