"Indispensable" is the language used in the link I sent, so I was shooting for consistency. While it is possible to get what is needed through plants, obtaining protein from animal sources is far more direct, easy to digest, requires less material for the body to work with, and does not carry along the antinutrients (lectins, oxalates, etc.) plant foods so often deliver and which can be quite damaging to humans.

The argument is also not for feedlots, but for pastures — in a post below I argue for getting rid of the grains which we use to feed these animals (which isn't great for them to eat, either). There is good evidence (see Peter Ballerstedt's work for details on this) that pastured ruminants end up generating excellent soil that holds in water and is actually on the good end of things, methane emission-wise (though the problem of emissions from feedlots are greatly overblown as the pollution which comes from planting, harvesting, processing, and distributing plants rarely gets folded into the equation). Funny that.

And, finally, as for "getting enough" — getting enough to get by is not optimal for health. More & better protein is needed for that, and that comes from renewable animal sources which don't require vast expenditures of energy, processing, and which prevent the loss of topsoil while adding to the vitality of the soil. I want everyone to be healthy, and there's a path for that to happen, one which won't be taken if we go down the "plant based" path instead.

Oddly it was my calculus 1 final that clicked a lot of things for me. Turned out the authors of the test included a professor who could explain calculus much better than my lecturer for that semester. I remember feeling the most intense and lasting feeling of revelation for several days after that test.

This hand wavy advice of just going “out there” and interacting with people is unhelpful[...]

Please.

I can't speak for you and there's no way for me to know what hobbies you have in order to give you precise advice for what you should do with your life. Nor do I know exactly where you live, what your culture is like in terms of socializing, and what social opportunities you have in your area. Nor is it my responsibility to do that for you.

So my post was intentional like that as it's up to you to figure out where exactly "out there" you need to go to fulfill your goal of improving your social skills as I can't do it for you.
It wasn't designed, it was evolved. The author said as much. Evolution seldom produce clean designs.
Aside from the fact that you're arguing that "company wipes out competition, raises prices" is some sort of fantasy and not standard business practice: How is Uber not a practical example?

VC-backed startup, out-competed traditional rivals using VC cash to undercut them, jacked prices and dropped quality once they had established dominance.

Uber and Lyft decimated the taxi industry. Taxi drivers lost but so did the public; we ended up with wildly variable rates, extremely discriminatory service (virtually zero handicapped accommodations), uninspected vehicles, background checks that were a joke, no licensing, no government agency responsible for keeping an eye on them, and no accurate metering (any cyclist with a bike computer will tell you that GPS and wheel-measured distance almost never line up.) In my city, you could call up the police department's livery unit and they would investigate reports of illegal driving, unsafe vehicles, lost property, etc.

Companies like FAANG don't move in to a new tech space and succeed because of "substantially better / innovative new business models." They usually have an inferior ripoff but it dominates because they can leverage their existing infrastructure, brand recognition, PR relationships, and giant piles of cash to pump into it until it succeeds.

This Indian entrepreneur is bleeding cash undercutting these local salesmen, and if it takes long enough, someone like Amazon will come in and do the same thing to him. But if he pulls it off, he's going to drop the one-day delivery and 15% price discount like a bad habit, guaranteed.

Amazon was bad when they removed the option to filter shipped and sold by Amazon many years ago. I thought Walmart was better, and it is because they let you filter for retailer as Walmart only, but recently they made it so it resets the filter every time you search.

I cannot blame them, since retail profit margins are so low. But as a buyer, I try to direct my purchases to the retailers that make it easy for me to not deal with resellers. So I try to use Home Depot/Lowes/staples/Best Buy more often. Target is decent, but they also have more and more third party sellers now and do the same thing as Walmart.

I think as a concept they might stay and find some use. In terms of art and collectibles though, I predict a huge crash within the next 2 years.

People now pay thousands of dollars for algorithmically generated images. How many of buyers pay for the "access to the community" and how many are speculators that just want to sell them later? Most of these communities that are created around NTFs will become inactive soon and with a nearly infinite supply of new NFT series, the resale values will drop by 90%+. A limited number of communities will remain active, and maybe their NFTs will increase in value (since they offer some exclusivity).

Same with people who now support graphic artists and photographers by paying $5,000 for NFT of some photo. Why people who have never commissioned anything now are paying so much for NFTs, and will they keep supporting artists when they realize that they can't make a profit anymore?

I'm curious what will happen, as I believe we're entering the "Peak of inflated expectations" stage [0]

I second your feelings. There is a module for a switch (I got one on my air conditioner) but it's uncommon. When I need one (example: TV) either I build a cable with a switch or I plug it in a power strip (example: RPi and USB hub). I buy only ones with individual switches on every socket.

You say "There's a formula with a triangle ..." without telling me where. That's not real helpful, and you're making me do the work to find out what you're talking about. If you want assistance to get started, you need to be more explicit.

However, I have done that work, so I've looked, and in the second column of page 210 there's a "formula with a triangle":

t_c = 5 \middot 10^{-5} \sqrt( V / Dt )

... where the "D" I've used is where the triangle appears in the formula.

But that can't be it, because just two lines above it we have:

"For a pulse of width Dt, the critical time ..."

So that's stating that "Dt" is the width of the pulse, and should be thought of as a single term.

So maybe that's the wrong formula, or maybe it was just a bad example. So trying to be more helpful, the "triangle" is a Greek capital delta and means different things in different places. However, it is often used to mean "a small change in".

FWIW ... at a glance I can't see where that result is derived, it appears simply to be stated without explanation. I might be wrong, I've not read the rest of the paper.

The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful, and document what you wrote so you don't have to answer so many questions about it. Hence, the first great virtue of a programmer. Also hence, this book."

As a starting point you can check out the notation appendices from my books:
https://minireference.com/static/excerpts/noBSmathphys_v5_pr...
https://minireference.com/static/excerpts/noBSLA_v2_preview....
You can also see this excerpt here on set notation https://minireference.com/static/excerpts/set_notation.pdf

That covers most of the basics, but I think your real question is how to learn all those concepts, not just the notation for them, which will require learning/reviewing relevant math topics. If you're interested in post-high-school topics, I would highly recommend linear algebra, since it is a very versatile subject with lots of applications (more so than calculus).

As ColinWright pointed out, there is no one true notation and sometimes authors of textbooks will use slightly different notation for the same concepts, especially for more advanced topics. For basic stuff though, there is kind of a "most common" notation, that most books use and in fact there is a related ISO standard you can check out: https://people.engr.ncsu.edu/jwilson/files/mathsigns.pdf#pag...

Good luck on your math studies. There's a lot of stuff to pick up, but most of it has "nice APIs" and will be fun to learn.

As a side note, and essentially reserved to EU/Italian nostalgics, there is now a small firm retrofitting the Piaggio Ciao as an e-bike:

https://www.ambraitalia.it/cosa-facciamo

For those too young to remember the times, in the '70's the Ciao had become a synonym of "moped" as much as Vespa was a synonym of "scooter" and was ubiquitous.

The finally assembled thing will probably be way too heavy if seen as a bike, but on the other hand the original Ciao was designed for 40 km/h speed, so at 25 km/h body, wheels and brakes should be "safer".

I read the whole article, and I don't understand.

Coding theory is hard enough, but when it buried under layer after layer of analogy to make it more digestible by non-mathematicians I can't see what the author is talking about. I know that it's challenging to make a field like coding theory understandable, but is it worth it? Who benefits from this article.

The non-mathematician basically sees that some kind of a thing makes sending correct messages easier and that there has been a revolutionary breakthrough because of something to do with "rate", "locality", and some other kind of squares connected to squares in a graph that's not a graph or whatever. But whatever it is, its a breakthrough. Why is it a breakthrough, I'm not sure but it's amazing or something.

The person with some idea of coding theory likewise doesn't get anything out of this article unless they are already familiar with the C^3 question (i.e. Is there a locally testable code with constant rate, distance, and locality). This is an area of research in coding theory and thus understood by very few readers even amongst those that have been exposed to codes as a student or computer scientist.

Consider the concept of locally testable codes, this is what the research is all about. The author of the article explains it:

> What if you could encode a message so that it would be obvious if it had been garbled before your recipient even read it? A book can’t be judged by its cover, but this message could. They called this property local testability, because such a message can be tested super-fast in just a few spots to ascertain its correctness.

That's it. That's the definition of an LTC given in this article. I'm sure the writer in trying and likely fighting with his editor who is saying "That's too complicated, our readers think a string is used on kites and a bit is used to control a horse, so dumb it down for our readers and bring it back to me."

HN readers that would like to know why the reported results are interesting or want to dive into the results can look up LTC on Wikipedia where you will learn that a LTC is: "A locally testable code is a type of error-correcting code for which it can be determined if a string is a word in that code by looking at a small (frequently constant) number of bits of the string.", see [1]. The mathematically inclined can then look to a lecture prepared by the original researchers, see [2].

The immediate point that you are obviously ignoring is that no one you are replying to has even suggested anything that you seem to be arguing against.

It looks like you are responding to someone saying "ban all cars, anyone living somewhere unwalkable just has to suck it up, regardless of any extenuating circumstances"

What was actually said was "LET people run errands by foot and by car", and "I'd like more awnings"

Basically - make places more walkable. "Low hanging fruit" meaning focus on making nearly walkable places into very walkable places.

I am a parent with small children. We walk to school. With a baby, I would walk to the supermarket, no one got ill any more than the occasional sniffle. Combining a pram and a backpack meant I could easily bring home the weekly shop, much easier than I can now that I have to carry everything.

It's also about places that are wantonly and deliberately hostile to pedestrians. Don't make people drive between adjacent destinations, don't force people to walk 2 miles to get somewhere half a mile away.

If you live in a village with a baby and an elderly parent and your nearest city is Timbuktu or Nuuk, this is not about you.

After that system was obsolete I threw it away but now I miss it because it would make a great Win XP retro gaming system.
