> And flights costing 29 EUR are simply a market (and policy) failure. In no reasonable sustainably operating economy would we ever have gotten into a situation of flights being cheaper than train trips.

Mostly ... you don't.

To get that 29 EUR flight you have to book it WAY in advance, generally be on a trip that isn't super popular, and be willing to have no luggage to speak of.

When we were in England, France and Italy pre-Covid, we priced out moving around on the train vs moving around on planes.

The trains almost always won (sometimes by quite a lot) and had the advantage that you could buy the tickets with a day or two of advance rather than planes which required 2 weeks of advance to get a sane price.

Now, obviously, we were moving between big cities and didn't need a car (because "tourist"). Business travel would probably be a different beast.
I enjoyed this article, and had never heard of Bowie Bonds! But isn't the sharing of risk in exchange for value just the concept of a full time job in any country with labour laws?

I work for a large multinational in a country other than America. I put up with additional bureaucracy compared to the life of a freelancer/contractor because I know that A) The company has a high chance of existing in 12 months B) I won't be fired without cause. In exchange the company is provided value in excess of my wage, training and other overhead costs. How is this different?
I think it’s important to remember that accommodations accommodate a wide range of people and so they’re not one-size-fits all. A parking spot might have been a “bullshit” accommodation for your situation but for others it might be absolutely critical. If an accommodation isn’t necessary for someone’s disability they’re free to leave it open for someone who does.

Is absolutely awful Prolog style :)

First of all it's hard to read, not least because you have your semocilons (semicola?) formatted inconsistently: some are at the end of a line, others at the start, so it's different to follow the program flow. More importantly, it's hard to see at a glance whether some "cases" are meant to backtrack on failure or not. Normally, if you wanted to write a Big Hairy, Horrible Case Statement in Prolog then you should at least use the control flow with ->/2 which amounts to a "soft cut" after the first <condition>:

( <if-condition>
-> <then-consequence>
; <else-alternative>
)

But the recommended thing to make your code easier to read (_and debug_) and less like they do in Java is to use separate clauses to handle different "cases" of your program's logic.

Also, bad idea to interleave messages to user with "business logic" like you do, e.g. in:

lives_with_others(Person),
format(atom(LivingWithPeople), 'anyone living with ~w', Person),

It's possible with a bit of elbow grease to completely separate the I/O of communication with the user from the rules-based logic of your program.

If anyone would like to know more then read this paper from 1991 by David Goldberg What every computer scientist should know about floating-point arithmetic, very accessible content even if you are not from CS field.

http://pages.cs.wisc.edu/~david/courses/cs552/S12/handouts/g...
There was a time when I thought (like you) that everybody should be using interval arithmetic, but then I came across a counterexample that convinced me I was wrong. I don't remember the precise example, but maybe the following will do the same for you.

Say x = 4.0 ± 1.0. What is x / x?

It should be x / x = 1.0 ± 0.0, but interval arithmetic will give you [3/5, 5/3].

Notice the interval is objectively wrong, as the result cannot be anything other than 1.0. Now imagine what happens if you do this a few more iterations. Your interval will diverge to (0, +∞), becoming useless.

The moral of the story (which may be more obvious in hindsight): interval arithmetic is a local operation; error analysis is a global operation. Naturally the former cannot substitute for the latter.
Yes, something like this should exist, but its very tricky to do as this is a global resource.

There are few enough sats that it often still works as 'I know the guy who does operations at XY company or government and how to call them'.

Unfortunately there is not even a global index of all sats with an easy way to reach the operator. Such a list exists but the phone numbers are often simply the public number of the space agency of that country. And getting from the China Space Agency to the person that can actually move the Sat it can be tricky.

Not to mention that there are dead objects that simply can not be moved.

The state of the art is moving forward slowly, both in monitoring and avoidance.

> Bitcoin's rising power usage doesn't achieve a greater capacity, it's simply the result of an arms race between miners.

When the difficulty rate rises the network is more difficult to be attacked. The upper limit to the difficulty rate is the point at which the miners can be profitable. We want the network to be as secure as possible. Though, I would say that we also want the network to be as efficient as possible (ie larger block size for more tx per block) like in Bitcoin Cash.

You can't upgrade it if payment systems change.

It's impossible for an implant to be 0 risk.

Removal is more complicated than implanting.

You can't change the data on it, so if you get skimmed you need a new implant.

However if it is re-writable (some are) you'll need to know someone/buy expensive specialized hardware.

I say all the above as someone with a magnet implant in my finger for the past 6 years. I still love having done it. But for practical uses like payment systems in an implant sounds like a horrible idea. (https://en.wikipedia.org/wiki/Magnetic_implant)

The problem is that the source is generalizing, which is fine for saying beta has usually shorter range and is less dangerous than gamma, but is too general to be applicable here.

Beta radiation just describes a certain kind of radiation, namely emitting an electron (or positron). However it doesn't directly tell you how much energy that electron has.

Wikipedia on Beta particles says that "Beta particles with an energy of 0.5 MeV have a range of about one metre in air; the distance is dependent on the particle energy." [1] Tritium beta decay just has an energy of 0.018590 MeV [2] and I wouldn't be surprised if reach isn't proportional but for example cubic (I don't know the formula) thus the huge difference in reach.

What I'm describing is an accounting trick. If you take an average, then make it smaller, then compare it back to the original average, there will be a difference.

Not clear how you are connecting this to the broken window theory, which as a side note, while often used fallaciously is not a fallacy in itself.
It’s not complicated at all. You are insinuating that Iran is a complex of nationalities which is patent nonsense. Iran’s culture is so dominant, so well defined, and has been so long before some Europeans got together after dealing with Bonaparte and coming up with “Nation State”.
That's why the idea presented - the idea that we can keep people awake 24/7 without negative consequences (or at least not enough of them to warrant alarm) - is so insidious.

It doesn't require anyone to subjugate or enslave anyone else.

Nor think of them as "sub-human" or try to convince a larger population that their exploitation is warranted. All it takes is for the substance or technology that allows for this 24/7 waking state to become legal and you're done.

The moment it's legal, warehouses, factories, the service industry, will start looking for people who can pull 10 hour shifts. If you can't do that then you can't have a job (or you lose an existing one.)

Then it goes from 10 to 15 hours. If you can't keep up, perhaps be cause you refuse to "augment" yourself, then you're unable to find work or loose your existing one.

This really isn't that far stretched.

Do you really think Bezos and his lot wouldn't be willing to invest in technologies that allowed an already underpaid workforce to go from 8 hour shifts to 15, 18 or 24 hours?

Of course they would.
I don't believe this is correct. The tritium is constantly being made. They are pumping water into a highly radioactivity area to cool the rods, but making tritium in the process.

> [0] Note that switching modes always costs time, sometimes significant amounts of time. In some cases it's time you may not have or may not be able to easily find.

When I land at SFO from an international flight, I’m on BART way before anyone could board a second flight after clearing customs.

Switching modes doesn’t have to cost any more time than switching vehicles within the same mode. You just have to design the systems to do it well. Train to bus isn’t magically less efficient than bus to bus. Neither is Airbus to train.

Switching to and from cars is pretty bad and usually inefficient though, that I think we can all agree on.

It would be foolish, of course, to blame hippies either for producing the misinformation, and, to a lesser degree, to pin the subsequent bad policy choices directly on them. They play a role in the latter, they do vote sometimes; a prominent role even, but not of course exclusive.

> higher vol [...] makes the option worth more.
> Similarly having more time to expiry makes the option worth more [...]

These two observations become unified when one observes that the two variables sigma (vol) and (T-t) (time to expiry) only ever enter the Black-Scholes formula together, as sigma^2 (T-t) (which is the variance of the log return to expiry).

(That leads to the observation that the unit of vol is 1/sqrt(time), normally a^(-1/2) [a=annum=year]).

Next, you alluded to it, but let's make explicit the way to trade implied vol: Suppose (WLOG) that you think implied vol is too low. Then you buy it (buy cheap, sell expensive...) in the market (buy buying calls and/or puts). Now you're long gamma, but short theta, and long vol in two senses: a) if the stock doesn't move, but implied vol goes up, you can turn around and sell the option back for a profit. b) you can delta hedge the option. Every day, you lose money on theta, but gain money on the movements of the stock. If it doesn't move at all, you lose the theta. If the stock moves "as expected" (=as implied by the implied vol), you'll just break even. But if the stock moves more than expected (that is, realised vol is higher than the implied you bought it at), then you make money. If the market comes around to your estimate of the future vol, you can then sell the option at a profit, or you can hold it to the end and keep delta hedging, and that will be profitable if realised vol turns out to be higher than implied.
Why would Japan being an island nation prevent it from handling this situation?
That would be a correct theory if you assumed that Iran is a rational actor. There is no evidence this is the case.

I would actually argue that NK is a fairly rational actor, if a slightly volatile one. Their "enemy" is Emmanuel Goldstein, they understand the US won't invade them but it is useful for them to pretend they will.

If Iran got a nuclear weapon, they would use it. No questions, they used chemical weapons before, they have gassed and bombed civilians, they don't care anymore (btw, the theory you are proposing was suggested before...Boris Johnson suggested it, he proposed giving a nuclear weapon to Iran, I studied IR, I am aware of the theory...it only works when a country has an incentive to not use nuclear weapons).
To be fair they are probably used to similar situations. Plenty of metal fixings in people today.

I've always been surprised that Reno isn't mentioned as a place for Silicon Valley to go to. It's only a 4 hour drive/1 hour flight to SF, near Tahoe, no income tax, and drastically lower property taxes than Texas. Couple that with the increase in remote work, and it seems like a no brainer.

That being said, I can't deny that I've been thinking about moving to Austin myself. The job ecosystem is there, housing prices are still cheaper than NYC, SF, or Seattle, and I personally like warmer weather.
> For now, the cost of Bitcoin is on top of the cost of the existing system, not instead of it.

You can have a closed loop of exchanging Bitcoin for goods and services without any legacy financial system involved. Just because you prefer to exchange your Bitcoins for your local currency does not imply that the cost of maintaining your local currency should be added on top of Bitcoins own.

Well which is it, then? You say Java is slower, the benchmarks say otherwise. What other benchmark would you accept?

I hate autoboxing as much as the next numerical processor, and I avoid JPA whenever I can, but that doesn't change that Java is plenty fast on a variety of workloads. It's typically only beaten by the hardest of the hardcore Rust and C++ implementations.

If options pricing is largely solved, do you think exchanges could provide an API where instead of specifying the price and quantity for hundreds or thousands of options on a stock, market makers could send a much smaller message containing their latest risk and model parameters, and have the exchange run a standard model internally to generate the quotes?

Since the model to convert parameters to prices and quantities would be known in advance to all traders, the next step could be providing a feed of current parameters which traders could use to build their own view of the public book. They'd still need plenty of quotes published piecemeal as now (as not all quotes would be model-generated) but the messaging could be much more efficient, and that could lead to more options trading.

I find this argument a little odd:-

"Frameworks do not keep retro-compatibility"

I would argue that is a good thing and in the case of Spring, doesn't feel true. In part, Spring is so hard to learn because it has too much support for legacy stuff (though this may have changed in the last few years).

The only issue with not supporting retro-compatibility is because the JVM doesn't support retro compatibility. I recently tried to upgrade an application to the latest version of Java (I think it was Java 12) and found that date formaters were completely changed to match an ISO standard which broke a lot of code. We also found a similar problem with the Java 8 transition as well forcing a huge upgrades to our libraries.

I am of the view that libraries and frameworks should support not support retro compatibility but the language should. This way, if you don't want to upgrade your library then you don't have to.

Using the web as an example, old Angular JS applications still work today as they did back when they were first written. I doubt applications written in the first version of Spring will work with the latest version of the JVM.
working outside of modern js ecosystem (react, node etc) would be my nightmare. There are tons of resources, best DX, continuous new features which actually make web performance better, and a vibrant community around it.
