"Life and fitness used to be deeply intertwined. You could not live without fitness. Now they are separate"

Say that to a Vizier in 700 AD. He was very flabby, no doubt.


I wanted RTL support (e.g. Arabic) with the new update and got this instead :(


Isn't modeling turbulence in two-dimensional completely different phenomena from (real-life) three-dimensional turbulence?

I thought this is why it's impossible to simplify turbulence models by 'ignoring a dimension'?


for taking a computational fluids approach, I think yes, you're largely correct. Hurricanes have a class of models that are parametric, where you can get a 2 dimensional wind footprint based on some initial conditions; primarily central pressure, size (radius of max wind), and location. These models rely on empirical measurements to get simpler. NWS 23 (0) is an old model, it's the one I've implemented before. But there's been more refined parametric models that have come out, and updates to older ones, for example the work by Holland (1) and Wiloughby (2). Take this with a grain of salt, since I'm no expert in this field.

This 'article' is a joke, just baseless fearmongering.


Is it factually incorrect?


Baseless?


I don't think reading one book is enough to learn linear algebra given its breadth and applicability. However the approach used in that one is very helpful if you want to learn functional analysis later on. But still, it probably should be read with other books that have more geometric flavour. Determinants are also a big magical topic of their own and show up in many areas of mathematics, so it would be a shame to banish them from the start like that.


A machine gun on wheels, really? Hope it doesn't accidently shoot one of those amazing super-charged engineers and creatives.


Actually medical students have the most loans, so unless you think that medical professionals are useless or that medicine should only be practiced by the rich, you should reconsider your views.

In most countries around the world higher education is free (or almost free) if you have the grades to be admitted, it's very a natural process. The fact that you have to take enormous debts to be allowed to study (which is your only hope for social mobility) in the U.S is the exception and is honestly crazy to me. How can you even speak of 'merit' in such society?


> so unless you think that medical professionals are useless or that medicine should only be practiced by the rich, you should reconsider your views.

Doctors and medical professionals are among the highest paid in this country[1]. Paying off their student loans makes the least sense.

> The fact that you have to take enormous debts to be allowed to study (which is your only hope for social mobility)

This is so absurdly false. It's a false narrative that's been pushed by higher-learning institutions for decades, and now regular people believe it. You do not need a piece of paper to earn a tremendous amount in this country. So very many blue-collar jobs earn six figures annually.

What's required to have social and economic mobility is a work ethic and skill. It's that simple.

Cite your sources about all those six figure blue collar jobs.


One google search turned up a bunch[1]. The thing they all have in common? Hard work, and skill. If you're skill-less, you aren't going to earn well, ie. if someone else can be trained to do your job in a day, you are not going to earn well.

It's a myth you need a piece of paper to earn well and live well. It needs to die.

We puppy-mill thousands of useless graduates each year and then are shocked they earn so little doing basic office work. In some cases, it's a complete inversion of what people expect - more degree less pay.

Only one of those jobs listed gets six figures and I’ll bet you need a degree or nuke sub background. The only other thing that gets close is police work, a career known for siphoning money from communities by doing bogus OT. Did you even read the link? Nice little ideological rant though, bet that made you feel good.


How about trying to do some of your own research, before you offer a false condemnation of someone's argument? This isn't reddit...

https://www.gobankingrates.com/money/jobs/working-class-jobs...

It's easy. I clicked the 3rd link on google.

If you live in a world where you believe you must have a piece of paper to earn six figures - then you've been lied to and you've bought into the lie. In other words, you've been made the fool.

There's so much evidence a degree is not necessary to have a very good life with a great income. You just choose to ignore it because it does not fit into whatever false-truth you've chosen to believe.


How about you come correct with evidence when you make bold statements that are trying to push some ideology you have. This isn’t Reddit.

That link, which is funny because it’s basically blog spam, lists: ATC(school and years of experience required), pilot(school and years of crap pay to break into those numbers), and then lists a bunch of other careers that don’t pay six figures or still require a degree (and you’ll be competing against people who have degrees to get).

Perhaps you are the one who should stop ignoring reality and update your beliefs. Best of luck with that!


It's amazing to me how you've put zero effort into your argument, yet remain staggeringly incorrect.

You do not seem to believe hard work and skill development leads to higher pay.

If you flip burgers at In-n-Out, you will not earn much ($15-20 per hour). If you manage an In-n-Out after putting in years of learning the business and working your way up - you earn close to, and more than often exceed, six figures.

Go ahead - look it up. Place some effort into your argument.

The point being - if someone can be trained to replace you in a day or less, you are not worth much.

ATC does not require a degree either [1]. I'm not sure what gave you that idea.

You don't have to believe me - you just have to put effort into your arguments. Careful - it might shatter your perceived reality.

There's no shortcuts in life. Hard work and developed skills earn big bucks no matter the field.

So your proof of six figure blue collar jobs being abundant is: a fast food chain, that isn’t even a national chain, where you have to work at garbage pay for years to MAYBE get a manager position (for which there are few and I bet they have degrees) where you might possibly get near six figure pay (in what are most likely high COL areas). Are you serious right now?

And the ATC not needing schooling is misleading. You’re only getting accepted via experience if you’ve served in the military as an ATC. Otherwise you need a degree. Go read the BLS overview: https://www.bls.gov/ooh/transportation-and-material-moving/a...

Also I’ve put effort into my argument, not that it required much. You’ve moved the goalposts from oh so many six figure blue collar jobs to maybe you can be a manager at in and out. Which just confirms the OPs point of a degree being necessary for real social mobility. Unless you think everyone in the country can be an in and out manager.

And finally, hard work doesn’t always earn big bucks. Plenty of people work grueling jobs and get paid crap. The break their bodies for nothing. You are just spouting more ideological garbage.


> Plenty of people work grueling jobs and get paid crap

Grueling has nothing to do with developing skills. You do not seem to comprehend this.

You need to develop skills that are not trainable in short duration.

What do all of the job types in the provides sources require? Hard work to develop skills that are not easily replaceable. That is what earns the big bucks. It's so simple, it's bewildering it needs to be said.

Your BLS link states "typical" - ie. not required, and only mentions associates degrees from community colleges. Additionally, the link to the actual agency itself, the FAA, as provided above, clearly indicates no higher education required. I don't understand how you cannot comprehend this.

You seem to think a piece of paper is somehow a shortcut to earning a large income - completely forgetting earning that piece of paper takes at a minimum 4 years - and often much longer.

You also seem to ignore majority of college graduates do not earn six figures straight out of school either. In fact, majority of college graduates do not earn anywhere near six figures[1].

In short, you are ignorant of the realities around you, and choose not to educate yourself on the facts presented and with minimal effort, available in abundance.

Minimal effort in life will cause you to have this outlook. It's disappointing you cannot understand the basic realities at play here. Work hard, develop skills, earn more. It cannot be any more simple.

With a little more effort, you too can be a high earner.

Well, you just learnt something about yourself from a HN article which pushed you towards a new resolution so it can't be a waste after all..


This is one of the first books I read when learning how to code :)


This narrative, i.e that the global plastic pollution in the ocean is primarily caused by a handful of Asian countries is misleading. It ignores the role of countries in the global north for overproduction of plastic and for exporting plastic waste to developing countries in the guise of trade. It also frames the problem as a "problem elsewhere", as if there is little a consumer or their local congress for that matter in global north can do.
