Actually a quite nice article. After also spending years as a professional physicist not understanding entropy, I finally decided that I was not necessarily the problem, and spent the last 5 years or so trying to understand it better by rewording the foundations with my research group. (I'm one of the papers the author cites is part of a series from our group developing "observational entropy" in order to do so.)

A lot of what makes this topic confusing is just that there are the two basic definitions — Gibbs (\sum p_i log l_i) and "Boltzmann" (log \Omega) — entropy, and they're really rather different. There's usually some confusing handwaving about how to relate them, but the fact is that in a closed system one of them (generally) rises and the other doesn't, and one of them depends on a coarse-graining into macrostates and the other doesn't.

The better way to relate them, I've come to believe, is to consider them both as limits of a more general entropy (the one we developed — first in fact written down in some form by von Neumann but for some reason not pursued much over the years.) There's a brief version here: https://link.springer.com/article/10.1007/s10701-021-00498-x.

This entropy has Gibbs and Bolztmann entropy as limits, is good in and out of equilibrium, is defined in quantum theory and with a very nice classical-quantum correspondence, and has been shown to reproduce thermodynamic entropy in both our papers and the elegant one by Strasberg and Winter: https://journals.aps.org/prxquantum/abstract/10.1103/PRXQuan...

After all this work I finally feel that entropy makes sense to me, which it never quite did before — so I hope this is helpful to others.

p.s. If you're not convinced a new definition of entropy is called for, ask a set of working physicists what it would mean to say "the entropy of the universe is increasing." Since von Neumann entropy is conserved in a closed system (which the universe is if anything is), and there really is no definition of a quantum Boltzmann entropy (until observational entropy), the answers you'll get will be either a mush or a properly furrowed brows.

I assume that this is why management is obsessed with hiring their competitors employees including developers. They want another but proven way of doing 'it'
I'm not sure what you're suggesting. What was the mechanism by which talk of higher rates reduced GDP? Consumer and business spending both increased. Personal consumption expenditures increased at 2.7%, and business investment increased at 2.1%.

The big drag in the report is from inventories and trade, which are being impacted by pandemic-related supply chain issues and geopolitics.

In terms of farmers retiring with a non-zero reduction of food produced but also farmers in north america getting more $ to ship their food overseas. In addition to food inflation pushing food prices up to unaffordable levels.

I agree with biden, food shortages will be happening.

The article focuses mostly on money and promotions but most of complaints I've seen at companies pressured to unionize have been around working conditions and policies. No doubt everyone would welcome more money but not all issues can simply be papered over with a bit more cash.

Where was this? I had a few trips to the grocery where specific items were out of stock or rationed (i.e. limit 2 per customer), but never saw a shortage of processed meats.
Yes, and once you manage to somehow become VP of This or Director of That, your career is pretty much self-sustaining. Your next job will be always be VP of That or Director of This, and your next job, and so on. You just have to get that title once, and then you're golden--there will always be another company looking for a VP, and you're now "qualified" by virtue of once having that title. Have you ever heard of a VP that ends up moving back into Individual Code Monkey Number 42010 because he can't find another VP position? Sure, some of these guys "Semi-Retire" and go back to a coding job for fun, but that's not what I'm talking about. I'm talking about: "Boy, the market for VPs is tough. I might have to take a lifestyle downgrade and go back to being a regular old middle-manager!"

I don't know, maybe it does happen, but I haven't seen it. The only time I've seen it is during acquisitions, where a gigantic company gobbles up a 10 person startup, where everyone at the startup gave themselves VP and Director titles, but again, not talking about that nonsense.
I love how you created a second throwaway just to further your point.

What about the PPC Macs? Yes, they were bad enough that Apple had to switch to x86—not exactly a ringing endorsement—but I'd say they were at least somewhat competitive, no?

Chrome can do the same via search engine shortcuts. This actually should be considered a basic browser feature, and as far as I can tell virtually every desktop browser since IE3 in 1996 does have it built in, it’s just not very well known.
The post opens with a false dichotomy. In general my experience has been that we hired someone that management selected because they'd "done it" before (always in very different contexts), they ramped up to our project, and it worked out pretty well. I don't think it's necessarily the best selection process, but selecting for prior experience is not a very serious problem in hiring imo.

Household debt to GDP has gone down since the low interest rate environment kicked off in 2010. Same is true for household debt as a percentage of personal income. Although I will note that its debt payments, not absolute amount of debt and obviously lower rates lower the interest portion of debt payments.

I agree there is something troubling going on but it's not a personal debt crisis

>The person who did "it" before may not actually be able to "it"; they rode the coat tails of a person who did "it". This "not it" person will often attempt to reframe the problem as one existing in one of the other areas; either as something were they are an "it" person or as "not my problem".

If we're talking meta issues, my far bigger pet peeve is how the market only wants to people who can do "it" to the point anyone who can't is expected to learn through observation, which loops back to most people only riding others' coat tails. It's cute in theory but in practice, most people need to try it a few times before having a firm grasp on the matter. Then it turns out, most desired skills aren't so obscenely difficult and arcane you couldn't just throw in a decently smart person at it and figure it out, as most tools are designed to be picked up in a short time (you know, like good, widely adopted tools are supposed to be).

The entire thing sets up a job market which supports "fake it till you make it".
Including "(rollable)" is really misleading. The main innovation is the new subtractive color mixing technology. The rollability is nothing special.
When you say "No hard tasks" I assume you mean that the engineering is relatively straightforward.

The surface of Lake Michigan is around 650 feet above sea level. Go 50 miles due west and you are at 800-900 feet elevation. The average elevation in Kansas is around 2000 feet above sea level! If you go southwest, it is naturally downhill - the existing rivers prove that - but you run into the problem that the water is heading south more than it is heading west.

It's a serious uphill climb to get that water out west. You don't need a sloped canal, you need a sloped tunnel thousands of feet below the surface!

Sure, but what about 1-2-3 years ago? The person I responded to said they never saw the point of taking on 30 years of debt, so my response was in more general terms.

Also, 2011 was still very uncertain. Would the market continue to go down, and would I keep my job were all real questions.

Is today a questionable time to buy? Probably, but what type of correction is needed in a ~7% inflationary environment for it to shift into an ok time to buy? 10%? 20%?

The point is there is always uncertainty and only in hindsight did 2011 look like a great time.
I think that the "microstate counting" approach - if that's what you are defending - doesn't allow to understand entropy clearly because only works for the microcanonical description. It doesn't make sense to count the microstates for a volume of gas at some pressure and temperature. (Which is the standard thermodynamics problem.)

The concept of how much can we tell about the microstate given only the pressure and temperature seems quite natural and a better starting point. Boltzmann's entropy is a nice illustration but there is no reason to avoid the general concept.
Either neither party can trust the other, and you need an intermediary to at least verify who won, and possibly to transfer the money; or both people are trustworthy and you can have a simple agreement. If it’s a third party, you have to trust that third party. We can’t get rid of the trust requirement. If the third party is software, what if there is a bug ? More like, when there are bugs
> Natural gas: one of the best out there. Low emissions

Per BTU heat output, natural gas outputs more than half as much CO2 (about 60%) compared to coal. That's not "low emissions" by any stretch.

Plus, the entire natural gas distribution system is leaky to an extent that is not fully understood yet. Recent reports suggest it is very leaky. Leaking...methane, which is 80-200x worse than CO2 as a greenhouse gas.
You will use a multimeter a lot more than an oscilloscope.

An oscilloscope is invaluable if something dynamic isn't working correctly. All that LCR stuff becomes real when you can see it. SPI bus and i2c bus issues become possible to visualize - though a protocol analyzer is even nicer, a scope will do.

I don't have a solution for trading but betting can be fixed by parimutuel wagering. Since that form of betting and payout is entirely algorithmic (and not based on the event itself), it can be done safely and transparently in software.

For anyone not familiar, this style of betting (used in horse racing) pays out based on the relative amounts waged on the winners. The house takes a cut of the entire pool and (in theory) isn't interested in the outcome.
The service/app looks great! Are there any plans for 2FA on the near roadmap?
Had an internal status page that everyone in the office would refresh often; the bosses decided that was a great place to put "message of the day" texts for whatever notices they liked. Of course they started writing 500 word messages every day, din't delete anything, and people stopped refreshing the status page, never having read the "management wisdom" that was being splashed around liberally over the actual important information contained on that page.

What worked was to put a 1 day time limit on management messages, and a 200 word limit. If they wanted to keep a message up two days they had to type it in again the next morning.

Also, we put a random "fortune cookie" text on the status page that changed at every reload, under the "management message" area. That encouraged people to actually read the words under the status numbers.

Everybody but management had a very positive response to running the "management message" bit through `cowsay`; too. Dunno if the effect would have lasted, but consider it for things that are important.
Imagine if we could travel back in time and show those Babylonians an iPad. They'd think it was magic. It's incredible to think how far we've come technologically but how similar we are mentally emotionally psychologically spiritually.
You shouldn't have, including it in the title is misleading here. As I said before, the rollability is not the innovation here.
Remember that you want to fail fast. The worst thing is to gestate and think about an idea for months/years. Just get it in front of people and try to sell it. If some companies decide to implement the idea in house that's OK. There are other companies, hopefully one of them will pay you to solve their problem.

When you chat to them get them talking about how bad the problem is, and all of the things that they have tried. 95% of the time they should be talking and you should listen.
I played around a lot and never got it to improve. I think it's just limited compute resources on the Pi and the fact that web browsers and websites have become massive. It takes a lot to a render a webpage these days.

It might have been lack of GPU. Moving windows around the screen was also really painful, probably 1-2 fps render rate as I dragged. I know browsers off-load a lot to GPUs these days too, so that could explain the slow browser rendering.
we recently redid authentication in our app - was told to do it exactly like Chase did theirs which I thought was an odd requirement. Come to find out the corporate executives get Chase credit cards so they were all using the Chase app and familiar with it and essentially told the products owners to build it just like the Chase and then told me/us the developers to build it exactly like the Chase app. Shaking my head. How dumb.

Anyhow come to find out Chase does this weird thing were even if you press sign out in app it essentially keeps you logged in and if you're using biometrics you can effectively unlock the app and get right back in w/ Face/Touch ID. We didn't implement that but apparently this executive clicks sign out when their done using the app and still expected to get right back in so we had to rebuild that part. F my life.
I use Pi 4 with 8GB of Ram and 1TB SSD (in a Argon ONE M.2 case) as the main local linux server but not for desktop/web. Access it from an iPad pro usually (the whole combo is extremely portable) and use remote/cloud servers when processing power is needed.
We seem to be stuck in a loop of explaining basic first-year statistical mechanics back and forth to each other repeatedly. I'm not sure why.

I'm making a pedagogical point. The OP addresses how difficult entropy is to understand. I'm responding to that. We don't need to talk about "knowledge" when you define entropy, or in an initial explanation of entropy. We could, but we could decide not to.

The log(x) example is a good one. First-time students who are learning about logarithms don't need to be told that a logarithm depends on 'knowledge' or on 'information.' It's ok to just tell them how logarithm is defined.

Sure, there is information. I'm saying it's confusing and unnecessary to introduce more big ideas like information, when the topic is "entropy is difficult to understand" or "logarithms are difficult to understand."

The Republican Party would like to "capture" whites the way blacks are captured, which would be good for them because there are more whites. It is one reason why the dems want to downplay race because if it really comes down to race than the majority wins.

It's a very bad thing when most people are choosing a party based on racial or ethnic identity because it turns a two-party system into two one-party systems. If you feel you have to vote for one party so the other won't win there is no competition to provide better public services, efficient government, peace, prosperity, etc.

> Some people really need to take a chill pill.

People can't take a chill pill because as we look around all the low hanging fruits of technological progress which bring about quality of life have been exploited.

We are in the refinement and small improvement part of the S-curve. Saturation.

Fracking wasn't as big as striking oil for the first time. EVs won't be like re-discovering the car all over again.

Conflicts and fear arise from scarcity or perceived scarcity. They will only go up as perception of scarcity rises among the population. When I say scarcity I also mean diminished rate of improvement, not just plain scarcity of oil, food , land etc.

Looking back at the late 1990s there were some quarters when the US economy grew at 7% YoY. Of course peple were chill back then, with that rate of improvement in quality of life everybody would be.

It's confirmed by the fact that the chillest and most loose countries today are Nigeria, Ethiopia, the usual suspects which grow at 9% YoY
Maybe also losing 1.1 million people (according to the CDC's "excess deaths" website) wasn't that good for our economy either.

The generics problem isn't solved with the introduction of generics either. What they have introduced feels limiting in ways that will solve none of the problems that I have had to deal with by using large amounts of code replication to avoid having to use reflection.

I like go because it provides a good WebServer STL, besides that, for my next web project I'm going back to using C++ or Erlang.
Isn't it 40 years??

My understanding is prices crashed hard in the 70s, there was a slight decline in 1990 and 2008, and other than that they've been going up 5-10% per year.
Very interesting work. Visual and diagrammatic reasoning are part of this problem, yes. It might turn out that some proofs that might be generally thought of as hard are actually "visually" justified, in a way that could even perhaps increase our power to justify mathematical statements. The extended paper Gowers links in his blogpost discusses one such case in depth, namely the well-known problem of whether a chessboard with two opposite corners removed can be tiled by two-square dominoes.
That seems like an odd mismatch between Biden and Psaki. Do you think it's possible Biden was speaking about the World, more specifically Europe, and Psaki was speaking about the US?
If not, I am curious as to why you think there is a mismatch between them on this issue.
