> it makes a philosophical error in that it assumes people and economic agents are inert objects to be studied as you would chemicals or atoms, without the capacity to react and respond to economic "laws" thereby changing them.

This is literally the foundation of macroeconomics AFTER Keynes. This is (one of several) reasons why Keynesianism was rejected.

Every single macroeconomist in every mainstream department in the country (and everyone in a central bank anywhere) would agree with exactly what you said AND say that it is precisely that fact which makes macroeconomics really hard.

This is why, for example, even the bare-bones simplest macroeconomic model you learn in your first year graduate macro class must include some notion of the agents' expectations.

It would be an error if we didn't do that. But fortunately, it's been at least 50 years since we started thinking about exactly that problem.
If they are shady, then it's high time to employ and enforce regulations - if they can't regulate themselves, then someone else has to.

Arguing that this is old news, and that a small minority has been "in the know" doesn't hold much water either - the crypto scene has long since become mainstream, and as such, attracted regular masses.

That's exactly what Tether has done?

Large sums? Check - tens of billions.

Gave out little? Check - https://cointelegraph.com/news/tether-explains-why-it-hasnt-....

Lied about solvency? They admit in this suit that they weren't 1:1 backed, despite asserting it on their website. They also claimed to be regularly audited, until they had to admit they'd never completed one. (Still haven't, to my knowledge?)
I'm surprised that you read a settlement narrowly focused on activities in 2017-2018 and apply it to today.

Tether was nearing a lifetime market cap of two billion when investigated. Their "100% backed!" claim at two billion turned out to be 13.8% backed.

They printed two billion USDT over the course of six days earlier this month. Wonder how backed that is.
I am not conflating trade with capitalism. I am explaining that the “feudal mode of production” was at best localized and relatively short period in the history of mankind. So contrasting capitalism with it is disingenuous because many periods in human history were more similar to what we have today than feudalism but there is often an implication that feudalism is the closest in time and place to the rise of capitalism and therefore it is the most similar one which is simply not true. If you look at the history of Rome it is much closer to what we have now in terms of its legal system, government expenditure, private relations, etc than feudalism. And they even had a similar sort of “capital” like private ships they used for trade that were very expensive, even though they didn’t have a modern idea of a corporation.

Indeed, exchange is not always capitalistic exchange. Capitalism can be analyzed as a system defined by 3 core properties: (1) private ownership of the means of production (2) labor market (3) commodity market. This is what Adam Smith called “the system of natural liberty” and what Marx called “capitalism” (I am not sure he coined it, but he certainly popularized it). Hence, when the government uses spends money on big infrastructure projects or hires people to work on a mine, it has little to do with capitalism, thinks like that existed in Ancient Rome and even Ancient Greece!

Compare our modern world to what we had 100-300 years ago when companies had personal armies. I don’t see how we are live in anything close to “hyper capitalism”.
It's a heat recovery ventilator, with a heat pump to move heat from the air into water.
From the marketing page:

> Compact P recovers the energy from the extracted air using a highly efficient counter flow heat exchanger. The remaining energy that is not utilised by the counter flow heat exchanger is used by the heat pump to produce hot water, and to further heat the supply air.

https://en.nilan.dk/en-gb/frontpage/solutions/domestic-solut...

HRVs take out stale air, bring in fresh air, and pass both streams through a heat exchanger to heat up the cold air coming in (or vice versa in the summer) with efficiencies of up to 95%. This is a purely mechanical system - the only moving parts are two fans.

HRVs need a preheater in cold weather, so you don't have condensation or ice form inside the unit, however if your climate isn't that cold (and most importantly your home is well enough insulated), that heat can be more than enough to maintain your home at a comfortable temperature without additional heat sources.

In OPs case the preheater is using an electric resistance heater, but as they said there are options to buy a heat pump preheater, using the ground as a heat source but it was too expensive (they are typically more than the heat exchanger itself, plus the cost of installing the ground pipes). Using the miners as a preheater just reduces the work of the electric resistant preheater. If you take into account the value of the crypto currency produced, then yes it is better than using the built in preheater, but using the ground source heat pump preheater would result in an overall lower electricity consumption.

The heat pump part is purely on the exhaust air. There is always some loss in the heat exchanger, so if the incoming air from outside is 5c, the exhaust air to the outside may be 10c. This unit runs the exhaust air through a heat exchanger to produce hot water for taps, and if that is already satisfied, to attempt to preheat the incoming air to reduce the work of the preheater. (There's probably also an electric resistance heater for the hot water, in case demand is greater than what the heat pump alone can provide).
This is a pretty useless metric for anything other than shock value.

We have driven our Teslas tens of thousands of miles and have never once been in fear of running out of juice. I can even charge at any 120V outlet in a pinch with the mobile connector [1]. In the very unlikely event of running the car down to 0% SOC, AAA will tow me to the nearest Supercharger [2], J1772 charger [3], 220V outlet, or our high power wall charger at home.

Range anxiety is overblown and well past its expiration date as a concern for EV uptake. Tesla is selling half a million vehicles a year, and yet, we hear very little of folks running out of power on the side of the road. Go figure.

> I don't understand the insistence on being "fully EV." Just toss a 5 gallon tank and a small gas engine and generator in in every electric vehicle until batteries have a chance to iterate a generation or two.

Tesla is trying to say the computers parts in their cars are actually consumables that need to be replaced. They argued eMMCs were consumables and would require a $2000 fix. The regulators had to step in and fore their hand to do recalls.

Car manufacturers will need to keep their service centers happy by putting in serviceable parts. Tesla’s the only large exception since they lack a dealer network but they will eventually play the same game.

Let's be clear, here: There's a substantial difference between Bitfinex engaging in outright financial fraud vs a bunch of people buying into the value of a virtual currency for reasons no one can understand.

BTC is not a ponzi. It's just a long-running speculative bubble. A collective delusion. You can disagree with that, sure, but it's certainly no more a fraud than Beanie Babies or tulip bulbs.
As long as there's a vote/like/share/other counter, people are going to be incentivized to act like that. It's the part of our monkey brains that are desperate for approval from others.

I wonder if the solution to that problem is better education, like we teach kids not to do drugs. Both drugs and internet points activate chemicals in our brains that make us feel good, and both fuck us up if we do them too much. Yet we're able to coexist with drugs, but having problems with social networks.

Maybe we need PSAs and cheesy slogans with mascots to tell us that "cool kids don't dopa-meme!", and hip celebrities kids can identify with (Youtubers?) to casually mention that they don't use gamified social networks, etc.

That's simply your white fragility speaking. For those with experience speaking on the subject, it is simply another (rather crucial) aspect of the science as it applies to our contemporary society.

The article was sufficiently neutral; your hysteria is the only issue.

Food is politics. Until we're back to scavenging from the nutrient-supporting biome in our immediate vicinity - as long as diet is subject to policy and public sentiment - what is and isn't available to eat and how it interacts with our bodies is inherently both scientific and political, and both deserve mention at points of intersection like this.
Then it's totally fine to pick another commonly used data exchange format which is better defined, that's still much better than hiding the data format behind an SDK.

However, we're coming from XML, which was better defined, and there are also binary "quasi standard" formats like protobuf, so those problems had already been solved.

Yet still "the world" has moved to JSON, which seems to indicate that those problems probably were not all that important for most use cases.

> What exactly is wrong with the notion of having technology companies pay for links? The links and content are a form of intellectual property that is collectively produced by users and firms in a nation, and a law like the one passed in Australia effectively just functions as a form of collective bargaining over that information with Google or Facebook.

A link is how the web has decided to say "go here if you want to learn more". It doesn't make any sense to me to make people pay to tell you where you can go find out more about something. It becomes a tax on the transfer of knowledge, which is the worst tax idea I have ever heard in my life.

It also creates perverse incentives. If Google and Facebook have to pay to show you the news, then their obvious incentive is to either not show you news, or make you uninterested in the news. Do you really want a world where Google and Facebook are motivated to convince everyone that the news is a lie, or that it's not interesting, or that the best sources of news are tiny conspiracy theory outlets that are too small to actually have to pay for news?

Also consider that most people use the news as part of their decision on how they vote. Having "the most powerful and profitable technology companies" in the world motivated to mess around with something that directly feeds into the voting process sounds like something that will inevitably lead to a crisis. They helped create the Capital invasion on accident. I shudder to think what will happen when they really start tinkering with the news.

> Why do we need to accept the logic that the most powerful and profitable technology companies in the world get to utilise our data for free?

Because knowledge should always be free. No one should ever be too poor to learn. I accept that sometimes other people will do things I don't love with that knowledge.

> Why do we need to accept the logic that the most powerful and profitable technology companies in the world get to utilise our data for free?

Also, I can see at least 3 other potential solutions in that sentence that don't involve changing the word "free".

"powerful" - use some of your anti-monopoly laws then. They're meant to break up companies that become too powerful.

"profitable" - cool, tax them then. That seems to be the route France is going, and closing down the loopholes where they shift money around.

"world" - if they're that bad, then ban them in your country. I'd rather live in a world without the conveniences of Google than a world where someone can be too poor to know what's going on in the world.

Hi HN,

I’m Justin, and I’d like to get some feedback on Indie Adviser. It’s a web app I initially built to support my own independent state-registered investment adviser (RIA) business. I’m now planning to market it to other financial advisers. I’ve set up a dummy login button for HN visitors, so there is no need to create a real account.

It’s designed to complement an adviser’s existing brokerage portal, adding portfolio optimization and cashflow projection tools, as well as some client recordkeeping that I think is specifically useful to RIAs. These are modules typically included in a big-box wealth management firm’s proprietary toolkit. The idea is to help financial advisers go independent using a modular toolkit that can work alongside any brokerage portal. I personally use Interactive Brokers, and that’s the only brokerage connection currently implemented.

The modern portfolio theory optimizer generates mean-risk efficient portfolios (https://en.wikipedia.org/wiki/Modern_portfolio_theory). Modern portfolio theory has been criticized for 1) relying on variance as a risk metric and 2) forcing an assumption that asset returns are normally distributed.
The portfolio optimizer solves the first problem by allowing for alternative risk measures such as semi-variance and loss thresholds. I prefer semi-variance as a risk measure because it doesn’t count upside movement as risk. Semi-variance has been traditionally omitted from portfolio optimizers due to the simplicity of calculating plain-old portfolio variance. Portfolio variance doesn’t require a full calculation of the weighted portfolio returns distribution, as long as the covariance matrix of the individual assets is known. But with modern computing, I don’t see any reason to not “upgrade” risk measures. Note: the frontend only has the typical variance risk measure implemented.

To solve the second problem, I use a vine copula model for asset interrelatedness rather than the typical joint normal return distribution assumption. The joint return distribution generated with the copula model is the input to the portfolio optimizer algorithm.

I would very much appreciate any feedback. I’m particularly interested in feedback from any other financial advisers, especially those who do their own portfolio models. I’m also interested in feedback on the web app itself—I’m not a professional so I’m mostly learning as I go. And finally, if you work in institutional portfolio management and are interested in bespoke MPT optimizations, contact me!

Thanks very much!

You can inflate the money supply and still be "deflationary" if the convenience yield of holding the money (tokens, UTXOs, or whatnot) exceeds or neutralize that inflation rate. You make an excellent point, Bitcoin doesn't have to overtake gold or become a global-reserve to change the world. It just has to be a plausible alternative that enables people to opt-in or out of the system. It has largely already achieved that and I'm hopeful for a future of monetary pluralism.
