As an economist with a background in mathematics and physics I very much appreciated ‘econophysics’ and associated efforts, but a short while into my foray I began to realize that economics is afflicted with a dearth of conserved quantities. Physics has plenty of these (sometimes absolute, sometimes approximate) laws of conservation (conservation of energy, conservation of mass-energy, conservation of linear/angular momentum, et cetera) and these laws of conservation are critically important in constraining the dynamics a system can adhere to and thus constitute a kind of ‘shortcut’ that allows apparently intractable problems to be deftly solved by putting these constraints to masterful use. Economics has none of this. Even the apparently solid concept of ‘wealth’ (even in its weaker relative form) upon closer inspection has no fundamental basis: transactions between two parties can affect the market value of an asset and therefore increase or decrease the wealth of all of those who own (or owe) such assets.

The field therefore rapidly decayed into a form of “computational economics”. This might appear similar to “computational physics” and its use of finite element models and massively parallel simulations of particle systems to solve fluid dynamics problems. Trouble is, those systems are built up from elements that respond to the net of extant forces acting upon them, whereas in economics agents can and do act on the basis of what they expect those forces might be in the future. Self-fulfilling prophecies are “very much a thing” in economic and financial phenomenology: bubbles, crashes, recessions, booms, the whole business cycle itself...

Add to that that some actors, even very significant ones, in those markets might have really weird utility functions — for example, central banks seek not to maximise their utility — and that some agents are not rational at all (noise-traders, entrepreneurs misreading trends, & cetera) and you have another big flaw in the framework.

Addicting behaviour is dangerous, but you can get addicted to TV shows just as well. Gaming tends to be more addictive because it actively engages your brain, compared with traditional entertainment (movies, theatre, concerts) which are static, you just sit and watch.

As graphics keep improving I would argue that it might even replace cinema in the future, to some degree.

Also, gaming is just a vast area that it's hard to generalize the whole thing as "scourge". Some games improve critical thinking and can actually be great educational tools. Would you just read a boring history book or activelly engage in the political situation of medieval Europe by playing something like Europa Universalis.

Personal experience is that high intensity exercise mixed with a comforting ritual was what broke me out of a couple bouts of severe depression. When the streak was broken by an event or travel, and several days missing out on exercise followed, I would fall back into the depressive mood.

The most recent depressive bout was probably the most extreme I've gone through, and required a couple close friends to jump in, but again, routine exercise with comfortable bits of a routine mixed in - like making a cup of tea, making sure I have a podcast queued up, a book to read, and a handful of songs I like - has seemed to help pull me from the brink.

Now that I have eclipsed thirty years and I still am over 300 lbs, and some of the recent depression-like feelings, I am making a more of a cognisant action to keep working at this and to journal how I feel before, during, and after the routine.

I look forward to seeing this kind of work being taken a little more seriously as a means to treat depression as opposed to only medication and therapy.
Not that they don't make mistakes, but trains are another thing China got right and get very little credit for internationally. 25 year plan, baby. In the words of Bezos: Still day 1. Ha!
My biggest issue is train costs. I live in Edinburgh, and I can fly to London in 6 weeks for £19, or I can get the train for £160. The overall travel time is roughly the same, but at 6 times the price it can be very hard to justify. Especially when you have to travel with more than one person.

I'm a Viet, born and raised. My country is blessed with incredible scenery, diverse and natural. The coast line is as long as the country itself ffs. Now I won't claim that I'm an avid traveler, but from my limited traveling experience (only been to Australia, Korea, Japan and Hongkong on vacation, nothing too fancy), I have never been to a place that I would rank higher in terms of beautiful, natural scenery.

However, the one thing that always caught me off guard from the few oversea trips that I've taken is that _everything is so clean over there_. That's literally the first thing that I always noticed when I get there and when I came back. Makes me feel sad, envious, and shameful.
Wealth is most definitely not a conserved quantity.

Think of the equity of a typical household. It includes some equity in their flat, which has a current market value. Down the street a developer buys a whole building block at a slight premium to rid itself of extant tenants and in so doing drives up the estimated value of local real-estate, including our household's equity. They've just gotten richer. They could even remortgage their house and monetise that increase in wealth. They could sell it and buy a bigger flat in another part of town.

So no: wealth is not conserved. Quantified (maybe), but definitely not conserved.

Probably not terribly bloated, just old. The language (C), features (probably K&R C), libraries (pitiful compared to today), and portability concerns (nethack was ported to many platforms, DF comparatively few) it originally had to contend with made for a very different world back then. While I'm sure it's been updated/cleaned up over the decades, it probably still carries a lot of that design/baggage from the time it was written in.
Totally agree! Subtome was a great project but it lack updates. I talked weeks ago with @julien51, it's creator, and he told me that it didn't have time maintaining it but he would integer contributions.
You can find that in pretty much any underdeveloped area in the world. Not sure what exactly is the socio-psychological explanation for that, but poor societies usually just don't have interest/time/energy to take care about nature or even their surroundings when they have to work hard to survive.
Yeah, 20 hours for Rimworld seems impossible. I never got to the endgame, and I think on one playthrough I had something like 70+ hours before my colony collapsed. The game is hard.

That advice has a Michael Pollan (eat food, mostly plants, not too much) or Paleo Diet vibe to it. Perhaps a better term would be closer to what we would have encountered through most of the evolutionary history of our digestive system. In that time, nature hasn't generally been full of fatty meat. I don't know if that's actually true or if the theory of the diet is correct, but it is intuitive.

FP languages tend to consider correctness first, but treat performance, and predictability of performance, as second grade citizens. By performance, I mean both time and space, aka cpu and memory. Cpu is bad, but Memory is by far more critical.

This makes it tricky to correctly anticipate the outcome of a bunch of lines of code. One also needs to worry about the compiler, how it will interpret that, and this can be hard. Worse, the compiler's interpretation can change with a different version, or following a tiny source code modification that looked harmless. No one likes wild performance swings for no good reasons.

Add to that picture layers of abstraction that make debugging an executable more difficult, lack of choice and capabilities in said debugging tools (generally justified by "my code never has any bug!"), and it makes developing a headache, at least when things start to go awry. I haven't even started with 3rd party library supports, etc.

On top of that, one rarely codes in the void : a source code is going to be shared with a "community", so it's not a solo choice. One cannot impose a rarely used FP language to a team that know another language very well, and has never asked to change that.

Don't get me wrong, I love FP languages, and I can even see how some of their best concepts are being "borrowed" (ha!) by more declarative languages. That may be the best outcome. Maybe in the future, the differences will be less pronounced, the same way as RISC and CISC architecture have largely merged nowadays to inherit the best parts of both sides.

This isn't true.

There are sites that have public domain images and google has easy to use tools that sort images by licensing types. I make art and when I do need a reference picture, I use these tools. Most folks can do these things easily.

What Getty images does is sleazy because it makes it so that some of the tools available won't show a picture. Getty is charging for it and licensing it. This is different than them doing the work - they are taking it away.

He was really just having a dig at some colleagues, it wasn't meant as a serious proposition. In any case he's not talking about productive practical programming.

I learned the ropes on BASIC in the 80s as well and it was a fine introduction to programming as a practical task but e.g. is in no way any kind of preparation to understand theoretical computer science topics like algorithm verification and provably correct programs. They're different worlds and that's really all he was saying. He'd get students come into his classes who thought they already knew all about programming and hit a brick wall when they had to deal with the level of analytical rigour his classes required.

I hit this problem myself when I try to learn functional programming. I've had a go at Haskell a few times and got nowhere. I had a similar problem getting my head around object oriented programming. Switching theoretical domains can be a significant issue.

And what a world we would live in!
I also appreciate any methodological approach, if it seemed otherwise people excuse this.
But I am reasonably disappointed by the progress of econophysics given its implied ambition back then.

If there are physicists or mathematicians interested in economics, I would recommend two things.

First, delve deep into equilibrium analysis under uncertainty, game theory and mechanisms design and strategic interaction with externalities (e.g. social networks), to understand the "mathematical" and mechanical difficulties of modeling strategic human behavior under limited information. Pay ESPECIALLY attention to aggregation, e.g. when an outcome distribution implies behavior that we can influence, or when such behavior actually aggregates to overall outcomes.

Second, actually read into sociology and perhaps psychology. Here, you want to see how history dependence, the fluidity of meaning, institutions and the endogeneity of goals, may influence behavior. Behavioral econ and some experiments also.

If you, with these difficulties in mind, want to improve upon economic modeling, you are more than welcome.

But please, don't just rename the variables in a physics model.
> Although according to Google Washington DC has 700,000 people and Baltimore 600,000. Probably a more realistic comparison would be Bristol and Southampton/Portsmouth where there is realistically 1 train an hour (technically 2, but the second one has a change and runs 8 minutes after the first one).

OTOH between Macon (pop 34000) and Lyon (pop 500000) there is up to 4 trains / hour at commute times (1 an hour otherwise), over a slightly longer distance.

Blocking materials is the incorrect way to deradicalize people. I would further argue that by blocking it, the material is made to seem more scarce, and even more desirable for those who would otherwise not have been interested if it hadn't been blocked!

Outreach from social workers and societal safety net is the best way to prevent radicalization. I see legalization of drugs as an example.

I had a similar impression there too.

I think they have a difficult decision to make in terms of balancing raising the quality of life of the people through industrialization and tourism against preserving their natural heritage.

Here in the UK, it's easy to chastise Vietnam for not preserving their wildlife when we have nothing left to destroy. We already have a developed economy and we did destroy all the habitats in the process.

I don't think there is an easy answer for Vietnam and other places in a similar situation such as Borneo. I just hope the next generation have some natural beauty left in the world.
They can make them available through a paid portal, exactly like Red Hat or Canonical does with updates. But they can't license something that they does not own. Specially when they mix those images with others that they own and which they can sue you for large sums of money if you use them without license.

I can use CentOS workout pay dime to Red Hat.

I had an old contact there that was way up the food chain and he contacted her boss on my behalf -- who called and apologized and took the idiot woman off the case.

Big tech absolutely should be broken up. There is no such thing as Amazon -- well, there's Amazon the monopoly, but the Amazon you deal with is one of a 100 rent-seeking fiefdoms staffed with people who got picked last in school.

Collectively they do much more harm than good. (And that's ignoring the more pressing problem of political bias and censorship.)

Experiments. Try Them
That's true depending on the definition of money you use. Commercial banks can't create central bank money (M0). But they can create credit, and convert it to central bank money at will. And credit counts into M1+, one of the common money supply indicators.

I'd say "money" in common usage is only M0 (central bank lines) and MB (notes and coin), and the others are only technical indicators used by economists. But that's debatable.

> Those 2 libraries are the closest thing to the modern internet equivalent of the "Library of Alexandria". I hope they don't manage to burn in down.

This just reminds of how in the late nineties and early 2000s we used to have torrent sites for music enthusiasts with an archive of all the different versions, editions, bootlegs, all painstakingly added and catalogued, representing tens if not hundreds of man-hours worth of work by people who simply love music and wanted to share that love with other enthusiasts, creating some of the richest catalogues of music and music metadata the world has ever seen. And then it all was destroyed.

And this was true for many other topics of interest too.

We have burned many digital libraries in the last few decades, and we will probably continue to do so for a while longer.
Right, I found a couple inside the "3rd party" tab in ublock. This is great! Thanks.

From certain point of view, it has. When I started learning programming in mid 2000, closest thing I would use is anonymous implementations of runable in Java?

These days, I don't think there is a main-stream language in use, that wouldn't have functions as values, anonymous function declarations, closure scoped variables and at least the standard battery of higher order function utilities, like map, fold/reduce, filter, e.t.c.
