What I am claiming is that there's no difference in those two seats' prices at a given point in time. Yes, prices fluctuate, but that has nothing to do with the seats. When you purchase an economy ticket (assuming these two seats are both in regular economy), the prices for them is exactly the same at that moment in time. You're allowed to pick either one of them, and the price is the same. Wait a week, however, and the price will be different, but it'll still be the same for both seats.

I really don't understand why people on this forum don't understand this and why I have to spell it out in such explicit detail. It's self-evident.

Even worse, this means that, if the people in 34F and 35F purchased their tickets at different times, they could have paid different prices, but that doesn't tell us anything about which seat cost more. Either person could have paid more, depending on when they bought their ticket and how the airline adjusted pricing during that time. So, as I've been saying all along, there's no difference in value between those two seats, by virtue of their location on the plane.
it's been covered in a few documentaries (at least in Europe) but yeah it's still quite a low profile considering it's weight

We know many things in nature are fractals: coastlines, tree branches, blood vessels...

What if the Universe is one big fractal, repeating itself at different scales: electrons go around a nucleus, planets around a star, stars/galaxies around blackholes, and so on and so on, building larger and larger structures.
>I ask again: what would you use instead?

And I'll repeat what the parent said, again: decimal math.

>Most programs aren't doing "decimal math"

And yet they do. Most programs do decimal math with floats, either because the programmers don't know that's not a thing (and consider floats the same as decimals), or because the language doesn't give them anything else (e.g. Javascript up until recently), or because workarounds are cumbersome (e.g. representing as fractions or working with integers for money with a scale factor and downscaling in the end, etc).

But in almost all programs, the kind of math the program needs to be done, from money handling, to estimating distances, to layout, etc are better done as decimal.

Floating point don't represent a way to solve any kind of actual problem, except the problem of speed and memory representation. So their use is because of computer constraints, not because the problem domain requires floating calculations.
Anecdata, and unrelated to the back: With 100% correlation, anytime I start getting RSI symptoms, I can reference my training log and it turns out I haven't been diligent with the holy combination of face pulls and raw deadlifts. Data points of approx N=8, patient count only N=1.

No ergonomic chair, keyboard, mouse, etc required; just strength. And not a single orthopedist will discuss face pulls as a solution to RSI.

> IMO, if you believe in free markets, then your position is inconsistent if you also believe if you also believe in unconstrained wealth collection.

But if you believe in free markets, then your position is also inconsistent if you don't believe in unconstrained wealth collection. Because that's one of the things that the market sometimes does when it's free.

And I'm sure that someone will say "That means that the idea of a free market is self-inconsistent, and therefore we should abandon the idea." I think it is more likely that the logic in the parent's last paragraph is incorrect. Instead, one has laws to prevent wealth from distorting the market. (Tax the wealth to extinction is not the only possible form that such laws could take.)
Now THAT comment I agree with.

True story. Back in the Clinton days, there was a committee created to evaluate medical treatments and make official recommendations on which were cost effective and which were not.

Their first recommendation was that back surgery was not called for until the possibility of all other treatments had been ruled out. The data for this back in the 1990s was very strong and based on the facts, it should have been non-controversial. The data showed a fairly low success rate, and even for the short-term successes, a 10 year prognosis that was worse for equivalent patients than any alternative treatment. (Including "do nothing".)

The data notwithstanding, back surgeons as a group are very well off and tend to donate to politicians. Furthermore hospital administrators make more money off of back surgery than the others. En masse they began calling their local congress critter to say that something had to be done about this committee report. The result was that Congress got together and the committee report quickly got buried, and the committee's remit was changed so that it no longer could issue such recommendations.

As long as you can approach back problems with exercise, do so.

For my wife's problem? What worked was Valium to solve the back spasms, the disk slipped back in and luckily the nerves had not been killed while it was out, and then a slow exercise regime to stabilize her back. However until her spine was well and truly better and she had better stabilization, NOTHING to cause compression of the spine. (Which deadlifts do.)

Absolutely, in fact it's pretty easy and is routinely done by amateur and professional astronomers alike. We've had satellites, airplanes, and meteors obstructing astronomical images ever since we began taking them.

A very simple and common way is to stack all of the static images aligned on top of each other such that you have a set of values for each pixel corresponding to the same region of sky. Then sort the values of each pixel by brightness and keep the median value for that pixel. Or throw out that top and bottom 10% and average the rest, or throw out the top and bottom N, etc.

This is a standard feature of essentially all astronomical image processing software and has been for a long time.

If affirmative action has such clear evidence that it works, why do not the Swedish government implement it as a general rule for all their employees? Sweden has a very high gender segregation rate, around 85% of people that has a full time employment do so in a gender segregated profession, and government work places tend to rank at the very top as the most gender segregated work places.

If it leads to more qualified employees, which I assume would correlates with their suitability, it would save money and reduce mistakes in key areas like healthcare which then would result in saved lives. A national policy would be a win-win for everyone.

A while back I looked if any municipality had a general hireing policy in order to combat gender segregation. So far I have yet to find one that even mention gender segregation as something to consider when hiring new people. There does not even seem to be one that something as vague as a goal to reduce gender segregation.

“Petulant child”
I really appreciate Taleb's ideas in general, but this one strikes me as emotionally-driven, vastly more "intuitive" than substantiated.

It's a like a world chess master or NBA player telling others "play better!" — what Taleb means here, imho, is that too many scientists fail to propose models that fits his mathematical perception, his world view, but if it were that simple, he'd have a book called "system thinking".

He touches a lot on how he views things, so you can infer a lot of his mental framework from reading e.g. the Black Swan or Antifragile — both great in their own respect. But simple rules on this topic, that would/will be groundbreaking.

I honestly pride myself as a "transdisciplinary" mind (which comes with a lot of "imposter-of-all-trades" syndrom, but meh, it's also humbling to realize the path to knowledge may not be the most rewarding short-term path). Taleb is one of those relatively "wide" minds, he's able to speak with substance on a lot of domains, but like many abstract thinkers I think he displays a lot of the casualness towards the difficulty of actual implementation.

It's great to talk about systems but the reality is often about refactoring horrible codebases and if it works you'd rather spend more money on the actual mission that making things and concepts prettier. Even, especially at the edge.

My 2 cts obviously. TL;DR, I wouldn't look much into it. It's one of those things we only hear because who says it is famous, not because there's so much velocity to the idea.
What DoorDash pays, after expenses, and what’s happening with tips
When I worked for Berkeley our bosses made it very clear: they can’t stop us from billing more than 39.5 hours in a week, but if we did, they’d have to let us go and stop offering the service we provide, because they just didn’t have the budget.

It’s not like we were providing essential services. We were doing things to make the other students’ lives better, and we were all fine with the restriction.

We were also learning a lot ourselves in the process, and valued the work experience far more than the few extra dollars.

Aside from a few industrial uses, nobody buys "Coal"; people buy power. There is no differentiation. If it's cheaper to put in a new solar array with batteries than it is to continue burning coal, then power companies will shutter the coal plants.

This isn't really analogous to tobacco because there is no direct substitute for smoking. So long as people are addicted to tobacco there is a predictable and steady decline curve which allows these guys to milk it over time.

Ironmongers are also a much smaller - less important - share of the US economic pie than they used to be, back when US manufacturing was a much larger share of the economy. Now, granted, even with their lessened share of economy, they still of course carry outsized influence politically as proxy arms of the Pentagon.

As recently as the first Gulf War, Microsoft (for example) was a tiny speck compared to the military industrial complex. In five years or so, Microsoft's annual sales will be equal to about 25% of the annual US military budget (not meant to be apples to apples, it merely points out the massively increased scale of big tech vs eg 1990; Microsoft's sales for fiscal 1990 were... $1.18 billion).

To put it into tangible dollar terms:

Apple, by itself, generates approximately twice the annual operating profit of all US defense contractors combined.

Apple benefits from calm globalization, not war.

Big tech humiliates the military industrial complex on generating profits. And big tech is still expanding, whereas most major sectors are not. Which is to say, big tech money looks like it's going to double in size again in the next ten years (7% * 10 years).

AAPL + MSFT + GOOGL + FB + INTC + AMZN = ~$220-$230 billion in annual operating profit for 2020.

There are three trillion dollar corporations in there (Amazon is just shy of it; and FB will join them in that club within a few years). The rest of the world has one, which isn't really a corporation, in Aramco. It's $5.5 trillion in combined market cap. The Tokyo stock exchange is the third most valuable exchange by total market cap in the world, at about $5.5 to $5.7 trillion (the next two are US exchanges).

Same thing with Theranos. It was people on the internet who discovered theranos was shady and WSJ was the one that "broke the story". At least the WSJ acknowledged and credited the people on the internet who first pointed out the shadiness at theranos.

I think of it as less ironic, and more "There is a union constantly fighting to get Berkeley TAs paid more, and that union is more successful than no union at all, so Berkeley TAs are paid more."

It's a weird situation, since they are paid better than most TAs, but worse than a computer science instructor with that level of experience generally would be paid.
Carbon needs to be taxed to create incentives to reduce use, and for society to capture the externality cost of burning fossil fuels.
Elon seems to think so. He knows more about this than many of us. He may have reasons to hype the story a bit but I do think he’s sincere.

He also says there is another generation of hardware in the works. Not sure where that fits in. But if they can roll out a 2.5 -> 3.0 hardware upgrade, as they are doing, I don’t see what prevents them from doing that for 3.0 -> 4.0 hardware when the time comes.

Although I don’t know where that fits in, I do know where it does not fit in, which is into a made up narrative which falsely claims that Elon promised the hardware would never change and never be upgraded.

I realize that’s not quite in the spirit of your question but I’m also pointing out that the question may be moot.

Also the qualifier “major” is up for discussion. A replacement of the main computer motherboard certainly seems major on its face, but if it can be done by a mobile service tech in half an hour at a location of your choosing without you even needing to be there, then it’s not so major, in an important sense.
In case of war it can be forced to, the question is whether it is competitive with TSMC in medium/long run?
In reinforcement learning problems, significant improvement has been found from approximating the distribution of rewards for a particular action, rather than just estimating the mean reward.

DeepMind's research suggests that a similar model is at work in the brains of mice, mediated by dopamine. Each neuron has a different level of optimism/pessimism when interpreting new data, which leads them to capture different part of the reward distribution. Roughly, one neuron will converge on the 20th percentile reward, while another converges on the 90th percentile (technically, each neuron tracks an expectile rather than a percentile, but the intuition is the same).

This is a significant break from the previous model, which said that all dopamine neurons roughly just estimate the mean.
correct - I didn't think I meant Starlink would kill astronomy (I thought I was addressing some of the hyperbole rather than extending it) - but probably even at the level to be deployed in the near future we would see severely degraded quality of observations for solar system objects. Furthermore - I do think SpaceX is the "good citizen" here.

I don't think the next 5-10 companies launching constellation satellites will be quite as considerate, so one order of magnitude could creep on to two over 15 years.

I think image stacking has been simulated to work somewhere from okay to unusable even for 15s exposures - I think the trails are actually pretty bad due both due to quantity, velocity in the sky, and brighter-fatter.
indeed, but I wouldn't say "then again": I'd say that teaching kids Word isn't giving them any kind of computational thinking. Teaching them to write a small piece of code (and that exquisite feeling when you finally get it working) is very powerful.

It's similar to how mathematics is typically taught to kids in the systems I'm familiar with (US, DE, AU): mostly as syntactic transformations unattached to anything useful. Apparently the teachers have a propensity to be "afraid" of maths which is one reason they might choose to go into early education. The kids may be able to pass a simple maths test but not really have and feel for what it is.

You make some very broad statements here...

Cloud ERPs stay up to day whether you are ready for the change or not, it is not all rosy when they break important things at critical times of year. Traditional ERPs often don't get upgraded because there is no need. It is simply not worth the testing for the new 'features'. Lots of managers value the stability.

TCO is certainly not necessarily less, it is common for a company to move onto an ERP and stick with it for a decade or so. One off licensing can be much cheaper over this period than some cloud systems. I saw a system where TCO of was cheaper with the trad system after only 4 years.

Why? It wouldn't be able to cause you any harm, if true (according to our understanding of physics).
I also wonder if we'll see a greater push toward remote-first work, given the high carbon costs of physical facilities.

I wonder if there may also be a push to reduce some compute-intensive workloads, like training/scoring ML models or refreshing analytics dashboards that are not mission-critical and maybe not even actively being used.
Calling this a "glitch" is disingenuous. It (is/was) an open secret for my entire undergrad. There were plenty of professors who would encourage students on 8-hour appointments to work 20~30 hours/wk with no overtime pay. Professors control access to valuable research positions and grad school applications so if you wanted to have a career in academia there wasn't anything you could do about it.

I found a cure for my own lower back pain last year.

I had dealt with back pain throughout most of my 30s, and had self-diagnosed it as a bulging disc. Every few months I would lean over while brushing my teeth, or sneeze weirdly, or bend over to tie my shoes, and my lower back muscles would spasm and I'd be laid up on the couch for a week, taking muscle relaxants.

Early last year, I slowly came to realize that I had an unconscious habit of constantly holding my stomach in and tensing my abs. After unlearning this habit, my back pain is almost completely gone, and I haven't pulled a lower back muscle in about a year.
I do the exact same thing with Prettier. I get a little spark of joy every time my code snaps back into place :)
How is it inconsistent? You simply have to constrain wealth collection to ensure free markets.
That's awesome!

Although, all copyrights are Apple's on that particular file. I wonder if everything's been done by the book.
The variety of solutions people have mentioned in this topic is a testament to the complex and varying nature of back pain (and the body in general, if you'd like to go there).

I would therefore like to add my personal savior: Hamstring stretches.

Changing your lifestyle (not necessarily drastically) and excercising/stretching in general is the solution in most cases, yes, but for me the single greatest contributor was the hamstring stretch. Lie flat on your back, keep your legs straight and raise one until you feel its back sides burn. Strain it a little; using a towel, rope, bedsheet or spare pair of pants to pull on your heel if necessary. IANAD, but I hear it's pretty hard to injure your spine this way.
Yes, I remember this strategy from the 80s (Sematech). This kind of industrial policy didn't help anything.
You should visit indiehackers.com and see if anyone has advice on this there.

This would not surprise me, especially considering just how little you would need to catastrophically disable one of these factories. That said, I don't think this is a very practicable angle to worry about, since it's not just the factory you need to make the products. It's also the people, experience, and massive logistical octopus the factory is hooked into that makes it able to produce these incredibly valuable products. One minor deviation in a supply chain (i.e. a vendor switch) can mean millions of dollars in scrapped wafers. Just having the factory and its tools doesn't mean anything for an invader. It would simply become the most expensive waste of space on the planet.
Or you could pay works more so that, in their role as consumers, they can buy more.
It worries me that “artificial personas” are being systematically vilified. We don’t have AGI; these personas are created by humans running software, publishing content also made by humans running software. It is stereotypical pseudonymous publishing. That is legal and encouraged and explicitly protected.

Until computers can decide to publish by themselves, this is just another form of human publishing. Calling them “bots” is a slur. They are pseudonyms of the real live human running the software that posts under these names.
