Yes. Successful passive solar homes typically aren't all that passive, as they often need fans to transfer heat between the solar space and the storage medium (e.g., Hodges's house had pipes in the cement floor with fans; it was also common in other passive solar houses to have a massive rock bed beneath the foundation with air ducted through it). The traditional passive solar house where a mass floor is heated really only works in climates where it's sunny on a regular basis in winter (basically, the Plains, Rockies, and Southwest). If it can get cloudy, the house will need far more thermal storage and a means of heat transfer and control. The capital cost of the storage and system is considerable, and then operation requires maintenance. Also, the glazing typically needs to be covered overnight to keep from radiating all the heat out. It's not very passive. (I own a so-called passive solar home which is woefully lacking in storage; on a sunny day it'll heat up to 78F inside, but it will lose all the heat out the windows overnight).

Contrast with the one-two punch that is heat pumps and solar panels, each benefiting from mass manufacturing economies of scale. The heat pump can pull in 3KW of heat for every 1KW of electricity applied, and the solar panel can provide the electricity. The total cost is probably less than $20K, works just about anywhere, and provides air conditioning in the summer.

Suppose the sole developer died five years ago. Had he created an application for Windows, his users would still get to enjoy it. Had he created a FOSS application and given his users the source code, his users would still get to enjoy it. But if he created a closed source MacOS application, then his application soon joins him in death.

There is a fundamental equivalence between numbers and other concepts. Any concept can be mapped to any particular number based on the method of encoding chosen.

Intellectual property is saying that I own this particular result of turning a number into usable output regardless of starting number.

This is to say that we can't tell without actually decoding the number so we are in fact asserting that there is a chance we own any and all numbers if someone later publishes the encoding that would turn your number into a picture of a cartoon mouse.

Just pick one of your points that seems misunderstood:

> In my time, the hockey-stick would be an indication there is something wrong with the model ( instability ). "Nature does not behave this way"

But the popularly known "hockey stick" graph isn't a model prediction, it's a reconstruction of past and current temperatures. "Nature is currently behaving this way"... And as you point out, that's an indication that there's something wrong -- instability.
And because there are so many graphs, one would like to correlate.

Which is totally senseless now.

> CLEARLY, Robinhood knows about the infinite leverage bug, they have the capital, resources and engineers to fix it in a day if they want.

Not in all cases. Not all leverage is visible to them (though hiding it can certainly constitute fraud on the part of their customers). It's not possible to look at ownership of a security and conclude without error that the owner hasn't leveraged it in some other way.

I think the bigger question is whether or not Robinhood's bug constitutes an actionable enforcement action by the SEC. There are rules about how this stuff is supposed to be accounted, and I'm absolutely certain they're in violation of a bunch of them. A fine is probably the median expectation, but I wouldn't be shocked to see them fold entirely. Hell I wouldn't be shocked to see someone there end up in jail when this is all done.

While the attack is technically feasible, complexity and sophistication do not lend this to wide deployment. Someone with a lot of time, money and drive (think heist movie, or spy agency) to hack a person of interest might find this attack viable, assuming they find a line of sight to the mic. But if one's dealing with determined hackers, there is likely a multitude of other lower hanging fruit to first pick off.
This shook me. Obviously, I was on the opposite side of the opinion. I never had the experience working in a funded startup, I prepared my mind to join one (I already chose, a seed funded, likely to join in 2020) after the current company was acquired in January - Now, I'm confused. Of course, I understand the equity as a lottery ticket - I'm confident on the startup I chose will grow big, I'm interested to hear the negative side of your 12 year experience, especially the climax. Honestly, I'm in a opinion of cashing a 300K at the least after Series D or Acquisition, in 3-5 years.
There isn't an objectively correct basket of goods that is obviously the correct deflator to use, which seems to be a significant underlying assumption of your line of reasoning. The debate about which ones are the important ones to include in statistics like the US BLS CPI is a politically charged debate resolved in part by political means, not purely by the disinterested pursuit of truth. The CPI in particular eminently susceptible to drift over the years, since the goods in it change over time according to the Consumer Expenditure Survey — in 1973 people in the US were buying washing machines that are still in use today and Saran Wrap made of actual Saran, for example, and today they're buying washing machines that wear out in five years and Saran-free Saran Wrap. And of course it measures the prices of only mass-market consumer goods, not services (such as the essentials, child care and elder care) or custom or unique goods such as hand-tailored suits or buildings — a political decision, not an objective one.

If we want to be skeptical of carefully tailored metrics with thousands of parameters produced by political appointees, what standard should we use to measure the value of the dollar? Precious metals have been the standard against which currencies have been measured for several thousand years — the gold standard for measuring the value of currencies, you could say — and by that standard the dollar's loss of value since 1973 is about a factor of 25. This compares to about a factor of 2 over the previous 40 years, since 1933, and a factor of about 1.1 over the previous 140 or so years since the dollar was introduced.

I suspect that if you compare other goods which are, like gold and crude oil, verifiably produced to the same standard of quality in 1973 and today, you will find a similar factor of 16–32 in their dollar prices. I'm thinking of the most common grades of steel, aluminum, brass, portland cement, window glass, industrial electric motors, and so on. There will definitely be some exceptions — ±1% resistors are much cheaper now, to the point where you can't even get the ±20% kind that were the norm in 1973, and I imagine the same is true of specialty steels, synthetic sapphire, and a number of other things that were barely feasible at the time; and presumably photographic film has become more expensive, as it has ceased to be a mass-market item. If you're right about the cost of electricity "staying the same" — by which I assume you mean that, in the US, it increases in line with the BLS CPI? — this suggests that my hypothesis won't be true of coal. Do you have any other ideas?

Let's take anthracite, because it's the purest grade of coal, so it should be less vulnerable to variation in value from drift in grading standards. https://www.eia.gov/totalenergy/data/annual/showtext.php?t=p... suggests that nominal anthracite coal prices have risen from US$13.65 per short ton in 1973 to US$70.99 in 2011; https://www.eia.gov/energyexplained/coal/prices-and-outlook.... says that in 2017 they were US$93.17 per short ton, FOB the mine. That's a factor of 6.8, which is a lot closer to 6 than to 25.

"What people mean when they question whether employees would quit over an issue is that, if the employees aren't willing to quit over a cause, then that puts into question the authenticity of the demands being made."

I don't understand this argument. If you genuinely care about fixing the issue, then why in the world would you quit when you can instead stay and fight and have greater impact? Actively fighting from the inside of a powerful corporation that has real power to make changes is a much bigger lever you can pull than just quitting. These people are willing to risk their jobs to fight for what they believe in; how is it reasonable to accuse them of faux activism?

Microsoft for once acted very differently from its usual self, and Windows Phone repeatedly broke backward compatibility. Arguably even more than iOS did - and this was one of the factors in its failure. So this is not the argument against backward compatibility you think it is.

Besides, if you're comparing MS and Apple, you need to include all the VMs running Windows (it's not a physical device - but MS makes the same amount of money on it), and also MS's foothold in Cloud.

Apple practically does not exist in those spaces, and Microsoft would have been in the same position had it broke compat as often as Apple does on the desktop.

The common idea is that if you have to regularly roll out all your services, then you still basically have a monolith. So if you have a lot of shared code in libaries, there are no benefits to microservices. In our case, maybe we do have core libaries like to read from Cassandra, but you don't necessarily have to roll out everything if you improve them. Some pods could be even a year old

All the services have their own keyspace in Cassandra, there is near-zero cross service data access
I don't want to sound like I'm trivializing the scope of the problem, but there are articles about it almost every single day. There's only so much we can discuss as few of these seem to present genuinely novel information. At this point we know the science; the main barriers to action are political, and politics are generally considered beyond the scope of this forum. Again, I don't mean to trivialize it as I think that the subject should be getting much more attention, but let's face it, people come here for interesting discussion first and foremost.
Given a system with irreversible transactions you can always add structure on top to support escrow, chargebacks, or whatever other protection mechanisms you deem prudent. It doesn't work so well the other way around.
You keep saying "peer review" but I'm not sure how it applies here. The main way information was distributed in the era of the Federalist Papers was through newspapers, and at the time newspapers were almost entirely enterprises set up by political activists to advance the line of their particular faction. The Federalist Papers were written by several prominent members of the Federalists (see https://en.wikipedia.org/wiki/Federalist_Party), a movement that would go on to become the first real American political party, and published anonymously in Federalist-leaning newspapers. There was no "peer review" in the sense of any of their opponents reviewing them before publication.

If you want a good sense for what newspapering was like in the early American republic, I highly recommend Richard Rosenfeld's book American Aurora (https://www.amazon.com/American-Aurora-Democratic-Republican...), the story of a newspaper that opposed the Federalists and the price its editor paid for that opposition.

Let's not call this "peer-review" as if it were some sort of scientific process.

What you're talking about is a social acceptability test. Now, that's fine, so far as it goes. Every society needs mores and norms to govern behavior (and speech) in order to function. But let's not suppose that suppressing an individual's freedom to express thoughts not pre-approved is going to result in a net win for truth.

Can you define this? Everything can be done more efficiently.

A real professional engineers won't do premature optimization. You won't see bridges using some amazing new carbon material, it's not only too costly for the budget, it's also not needed (the bridge does everything it has to do per the requirement).

A real professional engineers will do the most he can with the resource he has, which is pretty much what we do in software engineering.

I'm not sure what the author's target audience is, but:

> But we know from high school physics that a = v' = p''

It would be exceedingly rare to see "p" used as the position variable in high school physics - it's almost exclusively reserved for momentum.

Most high school students do 1D physics with position as "x". Those who go on to study more physics usually use "s" as their displacement function/vector and maybe "r" as a position vector.

(Also, the overwhelming majority of high school physics students never touch calculus-based physics -- only about 50-60 thousand students take the AP Physics C exam each year. 5 times that take AP Physics 1, and even more take non-AP Physics.)
That’s if you expect to be on the hook for downside risk. If you’re a teenager willing to go bankrupt (and face criminal charges) if the bet goes south then you should maximize your risk.
> When do you mean? Right now Bitcoin is US$9400, which is almost exactly half of its all-time high value of US$19891 (in 2017). There are several times it has lost more than half of its value, but I don't remember a time when it has lost 90% of its value.

Looks like I overstated it slightly. It lost 85% of its value between its all time high December 17th 2017 ($19,891) and December 16th 2018 ($3,159).

The rest of your response, in my opinion, is immaterial. I can't imagine a soul who'd prefer their money to "fluctuate wildly"—to the tune of -85% in a year—vs slowly losing 1-3% per year. Especially when there are very accessible financial instruments (e.g., TIPS) to avoid even that.
If you can halt progress, you can make any particular person's holdings impossible to spend (if you can identify them), by refusing to include any blocks that include transactions from them. That isn't quite as lucrative as simply confiscating someone's holdings, but it's close; you can demand a ransom of a sufficient fraction of their holdings, perhaps 5% to 50%, depending on human nature.

(1) I know of one problem with C++17 and old code. C++17 removed throw specifications from the language (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p000...) . We use third party libraries that contain these which keep us from using C++17.
What I would like to see is what led to the pound being so badly mispriced in the first place. Did they just price it at whatever was the prevailing price? And was that why the Bank of England ended up with such small reserves?

Presumably they could have priced it lower and bought up Deutschmarks to bring down the price of pounds and build up reserves to start with when they decided to fix it.

There is also the question of how much Germany was contributing to the problem by keeping its currency overly strong, making it harder for other countries to stay in sync. Presumably if the Germans had raised interest rates somewhat and / or bought more reserves from other countries they could have helped relieve the pressure.

Glad it's not just me. I have an HTC 10, which was a flagship phone when released 3 years ago. Every single third-party app I use, including some moderately demanding games, works perfectly fine. Every single Google app is at the very least frustratingly slow, like Gmail, if not outright unusable, like Maps. It seriously pauses for 5-10 seconds anytime anything on the screen changes. One has to tolerate several such pauses to simply search for a location. This is on their own damn platform for crying out loud.

The best part is that 10 years ago I used to have an absolute piece of dog shit WinCE phone that failed to even keep up with my typing speed in its stock SMS app. Google Maps worked perfectly on that device.

“I try to show gratitude when it is appropriate, and it’s always appropriate, but you know when people do particularly good work I want to make sure that that’s recognized.”

Especially when he says "it's always appropriate". As a leader and professional, it's SO important to make recognition a key component of your culture. As a leader of an organization, you're a big part of what shapes the culture and by instilling behaviors that bring your team up, you're fostering a more positive and collaborative company culture.
