Comment Re:So the problem with that (Score 1) 137

Is that as a business which you really want is much much higher turnover than that. You want to get your customers in and then get them out after they've giving you money.

That just means you need to change your business model to one where the longer people stay, the more they spend. In the case of services around EV chargers, the sweet spot is about 30 minutes. You want to structure your offerings so that it takes a half hour to consume most of your amenities. Have a few extra options for people who might stay longer, but 30 minutes is the target.

So, what do you offer people who are traveling (other than fuel)? Bathrooms, obviously, but that only takes five minutes and you can't charge any money for it (not in the US, anyway; people expect bathrooms to be free for paying customers). If you're selling them gasoline, there's not much time left after the bathroom break, so you offer them snacks and sodas. If you're selling them electricity, you still have them for 25 minutes, which is just about right for a fast food meal plus some snacks for the road.

Your advantage with EV chargers is that your customer base is more "captive". With gasoline cars, they'll often stop for gas, then head to a restaurant a few miles down the road, maybe in the next town. But with EVs, they eat within walking distance of the chargers. They'll often do some shopping, too, if you can find the right goods.

One option to exploit this is to build amenities around your chargers, the "travel plaza" model. Another is to find a location with good travel amenities and put your chargers there, getting local businesses to pay you for the customers you bring them.

Comment Mastodon search isn't. (Score 1) 71

Join the Fediverse. It's cooler than Bluesky both literally and figuratively.

The problem I've had with Mastodon, assuming it's representative of fediverse microblogging, is that its search relies almost completely on hashtags. Full-text search is opt-in per post, and very few users have bothered to hunt for the switch to opt in and turn it on. Posts made before the introduction can't be found at all except through tags. And the users of Mastodon think that's a good thing because it protects vulnerable members of marginalized groups from abusive bigots searching for them.

This leaves users like me to play "guess the hashtag" all the time. I search for what I think is the right tag for a topic, and all the posts I find are my own. Or I write a post and nobody else engages with it because nobody else is searching for the tags I used. What am I supposed to do to get my posts seen?

This whole debate is a little weird to me, because unassisted suicide is very easy, and cheap. Out of an abundance of caution I'll refrain from describing common cheap, painless, easy methods, but the information is very easy to obtain online. So it seems to me that the issue really only arises if the patient is already severely debilitated by their illness, such that they lack either physical capacity to carry it out. Those situations occur, of course, but they're far less common that the scope of the debate would seem to imply.

Thus, I think the first step any regulation should apply is to ask the question "Is the patient physically capable of unassisted suicide"? If the answer is yes, then no one may assist, except to provide information. This alone should filter out nearly all of the "greedy relatives" cases. If there's a case of an individual who says they want to die, and is physically capable of doing it but just can't bring themselves to... IMO that's a case of someone who hasn't really decided they want to.

there is nothing behind it

There is unbreakable cryptography behind it. Science and math. That is 'harder' currency than any fiat that will ever exist. A truly secure and sound form of money, along with the transparency to shine light on all the corporate corruption in the world. Now. Tell me again it has no value.

Happy to: It has NO VALUE.

The problem here is that your definition of "value" is invalid. Your claim is equivalent to saying that shares of Apple stock have value because we have built systems to ensure that ownership of them is unique and non-duplicable, and that the supply is finite. But that is not what makes shares of Apple stock valuable. What makes them valuable is that they represent partial ownership of a company that produces and sells hundreds of millions of useful devices every year, among other things, and generates hundreds of billions in profits.

Shares of stock, dollars and bitcoins are all non-duplicable, finite-quantity tokens, but the shares of stock and dollars are tokens that represent something in the real world, while bitcoins represent nothing beyond proof that some electricity and some hardware was diverted to create them and transact them, rather than put to a productive purpose.

Yes, it's true that the guarantees of the non-duplicability and finite quantity are stronger for the coins than the others, which could theoretically make bookkeeping easier and reduce the need for auditing of transactions, but it turns out that the cryptoasset guarantees are hugely more expensive than the old way of bookkeeping and auditing, and the non-reversibility of crypto transactions is a fatal flaw for serious real-world use (though it's a boon for scams). If cryptoassets were easier and cheaper to exchange than traditional methods, and if there were a good way to address the reversibility gap, it would make sense for countries and companies to switch to using crypto-tokens rather than audited database entries. Maybe someday someone will invent a crypto-token design that achieves that, and then we'll trade shares of Apple stock by exchanging tokens on a blockchain (or similar). But even if we do that, it will still be the case that it's the ownership of a productive enterprise that provides value, not the token, no matter how elegant the cryptography.

Note that I'm not saying this because I don't understand the cryptography behind cryptoassets. I'm a mathematician and a professional cryptographic security engineer; this stuff is literally my day job, and has been for most of my 35-year career. I deeply understand the (actually quite simple, though cleverly assembled) cryptography and precisely what it does and doesn't do. It strongly ensures that there is a limited supply and that coins cannot be double-spent, and it does this in a decentralized way. That's it. The limited supply and non-duplicability are properties required of any asset, but aren't what give an asset value.

Most people fundamentally don't believe in markets. Look at how they react when prices rise due to a supply bottleneck or similar. They shout "Greed, we're being gouged!", even when there's plenty of competition to keep prices down and rising prices is actually the optimal solution to suppress demand in the short term and encourage increases in supply in the long term. Conservatives are worse than liberals these days, since conservatism/liberalism has evolved to be divided in large part by education level, and market mechanics are really non-obvious and counterintuitive unless you've had at least some level of formal (even if auto-didactic) education in basic economics.

I think markets are, to a first approximation, the ideal solution for every problem that involves optimization of large-group human behavior. Only when markets clearly don't or can't work should you even start to think about non-market alternatives, such as direct regulation, or even subsidies.

But shockingly few people agree. Carbon pricing immediately makes them want to know who's getting the money and why they should get it, even though that question is irrelevant to the primary goal.

I have great confidence in market-based solutions to rapidly move us toward optimal solutions to the climate problem. I have near-zero confidence that it's what we'll do. Heavy-handed, imprecise and mildly counter-productive regulation is the strategy we'll take, if anything.

99% of everything I type ends with a semicolon.

The other 1% are comments.

More like 80% for me. I use Rust.

(In Rust, an expression without a semi-colon at the end of a block -- including at the end of a function -- is the return value for that block. This is used heavily in idiomatic Rust, which means there are lots of lines that do not end with semi-colons. The more you use short, single-purpose functions and the more you program in a functional style, the fewer semi-colons you use.)

Someone has to pay for geoengineering as well. So if you ask people if they prefer to pay $1000/year in carbon tax or pay $10000/year in geoengineering fees to get the same results, the choice is pretty simple.

I think you present a false dichotomy. Several of the proposed geoengineering schemes are relatively inexpensive, though of course a lot of investment will be needed to demonstrate their practicality and effectiveness. I expect that geoengineering will be much cheaper than getting to net zero.

However, that doesn't mean we don't also need to get to net zero, because the geoengineering proposals only address warming, not the other effects of high atmospheric CO2. Ocean acidification and whatever is downstream of that is probably the biggest one, but there are others.

Geoengineering should be viewed as a short-term mitigation strategy, not a long-term solution. I think we'll need that mitigation, though. Assuming AI doesn't kill us all and render the whole question moot :-).

Comment Re:Oil companies' role in decline of transit (Score 2) 130

The alternative to diesel and petrol doesn't have to produce zero pollution. It can produce substantially less pollution. It's a lot easier to scrub a handful of power plants than to scrub millions of tailpipes. Not to mention that if the USA still had electric light rail in this century, a lot of it would run on wind and solar.

Remind me again who burns hydrocarbons. Is it the oil industry or the industries customers?

Think back to 1940, just before the United States got dragged into World War II. Chevron and Phillips Petroleum were among the investors in an joint venture to put the electric streetcars of California out of business in favor of fossil-powered buses. Others included Firestone Tire and Mack Trucks.
