Thanks, our beta customers love them so far! Regarding price, each occupancy sensor is $79. These are high accuracy thermal sensors with local machine learning that can count occupancy. For comparison, a standard PIR motion sensor that can only tell you if there was motion in the last 30 seconds costs around $50 from Philips Hue or Eve. We think the price is very fair! :)

Hm, if you consider storing something for a timeframe that well exceeds everything we are possible to plan ahead "safe". We simply put it in underground storages we consider "safe" for the time being. We have no idea what will happen with this deposits considering such a long timespan.

And this storage does not come for free. All these sites are maintained and must be. Just as much as the (very complicated) transport of the material. Every single castor transport in Germany and France is a huge operation.

And "Nobody has ever died from" is such a great argument. "Nobody has ever died from radiation in space" does not mean we should ignore it, does it?
> Nuclear power plants built in the 1970’s used 40 metric tons of steel, and 190 cubic meters of concrete, for each megawatt of average capacity.

> Modern wind energy systems, with good wind conditions, take 460 metric tons of steel and 870 cubic meters of concrete per megawatt.

First source I found.

Wind turbine lifetimes are 20 to 25 years at the best.

I agree for solar panels, they don't need lots of concrete and only loose efficiency over time. But you would need lots of them + a complete power storage system behind. So the cost and material used to have a similar power output is still order of magnitude higher.
The problem is the kind of nuclear reaction used. Fission reactors are bad, but once we got fusion reactors, we'll have an almost perfect energy source: clean, reliable and cheap.

The project Iter (http://iter.org/) is building the first fusion reactor. It's a big challenge but I'm glade that this project exists at all.
The graph of global emissions is a nearly flat line, we will be able to look back at any decade and say it could've bended there...ultimately, we just have decisions day to day that will bend it or not.
If we do get serious about intermittent renewable scale-ups without fracked gas backup we will have to build giant energy storage systems that the nukes will be able to feed into just like the solar PV and wind.

Additionally, nukes can be used for district heating, seawater desalination, hydrogen production, and lots of other non-electric things when the electricity demand is low by using steam bypass techniques.

Regarding correction: I meant to say that but thank you for pointing out that it made no sense as written. I have edited accordingly.
>The nasdaq 100 leveraged x3 on a daily basis returned like 50%+ YoY during the last decade.

And from 2000 to 2010, it was down 23%.

>there’s no reason why with $10B trading all asset classes one can’t return 70% YoY

There are plenty of reasons. First, if you have a small amount of money, it remains liquid. This is why HFT firms can have Sharpes around 8 - they can move the money fast because they are smaller firms.

If you have 10B USD you cannot respond to the market. You have to trade slowly and choose your positions to last a while. This leaves you with a Sharpe of around 1 if you're optimistic. Otherwise in your fantasy, you could turn 10B into 1T in 8 years.

Another reason is that as your portfolio scales, it becomes harder and harder to find uncorrelated returns.
Because they will persuade people who don't know any better.

9% interest! Buffet thinks the industry is toast, Lee is making a huge gamble (betting against someone who is known to make good predictions) and Buffet might never see that money again if the business goes bankrupt. Pretty odd transaction, maybe someone can explain how it is mutually beneficial.
Of the wild theories I've heard to explain the Medallion Fund, my favorite is the "money wormhole." I have no finance qualifications whatsoever -- I just stick my money in index funds -- but I love a good conspiracy theory, so here goes.

The idea is that you have two theoretically unrelated funds that take complementary positions with uneven odds. One sacrifices performance for the other, effectively transmitting money. The trick, of course, is doing this in a manner so that you have plausible deniability with regulators and, more importantly, so that other market players don't grab the money in flight, because that's what an efficient market would do. Still, consistently creating and hiding complementary pairs of good/bad opportunities is a much easier problem than consistently beating the market.

OK, so you've got a way to transmit money from a "sucker fund" to a "winner's fund" with plausible deniability, what do you do with this ability? In reality you'd probably have many "sucker funds," rotate the one that gets sucked, and limit the extent to which it gets sucked, but still, nobody's going to just buy the sucker fund, not for long, anyway. That's how efficient markets work. Well, one major, well-known, boring inefficiency is the principal agent problem: trusting others to invest your money. They can't just steal it, because that's illegal. They can't just invest in a private fund that they just happen to oversee and which just happens to pay them an enormous salary, because that's illegal. However, if they were to invest in one side of a money wormhole, which is designed to look like a perfectly reasonable investment on its own, in exchange for a cut of the proceeds from the other side of the money wormhole, who's to say the theft even happened? Such an accusation would need to untangle the coordination behavior of the money wormhole to make its case, and those inner workings could be made very convoluted indeed, hidden deep inside complementary pseudorandom behavior.

So, in short, the conspiracy theory says it's a heist -- but one that's well hidden under the veil of statistics and plausible deniability. It provides investment managers looking to monetize the confidence placed in them a way to make that happen without getting caught.

It's probably a dumb theory, but it's enough to entertain someone who knows as little about finance as I do :)

See that's where I have problem with this. Isn't data just _data_?

Lets draw some pararells to real life. If I go to public space like town square - can't I take pictures, notes and records then go home and draw my analytics from it? What if I read something in a book I bought, can't I quote it?

Same thing should be with web resources even if they are creative - as long as I don't publish them I should be able to scrape whatever public resources I want and use them in my analytics, machine learning or whatever.
This wouldn't supersede any violations of the ToS, though. I guess it would mean they can't sue you (maybe?) but they could still kick you off their service. Could they still go after you for breach of contract?

> We can use any and all power sources that are clean.

I would prefer if we did not use use any power source that is dirty. It might sound similar but the outcome is very different. A ban against fossil fuels would prevent countries from relying on fossil fuels for base load when wind or solar can't fulfill demand.

This only affects the ninth circuit—which includes the tech hubs San Francisco, Seattle, LA, and Portland. It would only apply to the rest of the country if the Supreme Court affirmed it. Even then, a well-funded company or zealous prosecutor could say that it doesn’t apply in your case because of some technicality. In that case you would need hundreds of thousands or millions of dollars and a few years to litigate the issue with no guarantee of the outcome.

Where do you think the money comes to fund those prisons? Taxation of everyone which is definitely society and not an individual.
EU calls for a common charger for all phones
The caliber is completely subjective, and Fantastic Mr. Fox made 1.16x box office / budget, so total flop. I’m not sure I understand how the fact that a different film that flopped made 10 years ago by a different company has a different budget demonstrates anything at all?

Lots of good films are made for less money, and lots of bad films are made for more money. Many many movies lose money. That’s the reality of movie making, it’s risky. Many many businesses lose money, those are also risky. That’s the extent of what you’re arguing here. If you really want to understand how easy it is to spend a lot of money and lose it, all you need to do is make a movie or start your own company, and witness first hand how good ideas and business plans that seem strong at the time fail to make returns.

It’s not weird or hard to understand when big projects lose money. It’s weird when they make money.

According to Plato, Socrates himself defended "noble lie" as in lie that "to maintain social harmony or to advance an agenda".

Besides, "ancient historians" were not historians in our sense of the word at all, so I don't understand why are you asking for historian specifically. They wrote a lot of obvious myths (falus appearing out of fire) and there is no expectation for those texts to be accurate.

Ancient texts were written for purpose and with limited knowledge (just like any contemporary text) and it would be oddly naive to think anything else.
Don't we already weigh trucks as they enter and leave the state, as well as sometimes in the middle of the state? I don't know what goes on there already, but we could certainly charge trucks based on loaded miles in the state, which should be pretty easy to calculate since they have very predictable driving patterns and take fairly detailed logs. For local deliveries, we could just charge based on the max load and allow drivers to prove anything otherwise.

And yes, consumers will pay regardless, but at least the difference is reflected in the cost of goods. It could very well be that certain local goods are cheaper than imported goods after road costs are properly factored in, which could change how much is imported.

However, this feels a bit regressive since poorer people will pay more of the cost since roads are largely funded by income tax, but that can be accounted for by shifting other taxes. The idea isn't too punish poor people or shipping customers, but to allow the market to work more efficiently.
If I'm doing my math right, and your two sick days aren't correlated with each other, I think you would have had a 16% chance of one or both of them occurring during a random 90-day period. Multiply out a few hundred of you, and that 30% in the study would be about 16%.

So no, doesn't seem like an overly high rate at all to me.

(4 sick days in 3 years would jump to 29%)
BenchmarkDotNet looks cool, thanks for that!

The problem is that I never had problems! (With LINQ-to-Objects performance.) That’s why I’m asking in the first place. Maybe I intuitively avoided all the pitfalls, who knows. It would be cool if you could share some (abstract) operator chains that caused problems in whatever you’re working on.

Is that the same Lee Publications that makes trade publications for agriculture and similar sectors?
We keep our house at 17C/62F. I also have wood instruments, some quite expensive, for which I track humidity with a slight bit of obsession. I say “slight bit” because in the Seattle area the indoor humidity of our house rarely exceeds 50%, usually 35-45% in winter. That’s about perfect for wood instruments, and it rarely varies much, so no need to get too obsessive about it. And our house doesn’t have a mold problem.

Point is, depends on where one lives, I guess. It’s odd that you call out Britain, as that’s about the same latitude and same rainy winter weather as Seattle, but our humidity stays within a reasonable range.
Both in the python version and so far in c++, I am using my own forward mode implementation in Numpy and Eigen, respectively. (Why? Well, it was easy, I wanted to learn, it’s been fast enough, and most critically, allowed me to extend it by using interval valued numbers underneath the AD variables)
Here’s where I do something kind of funny In the AD implementation: Basically just write a class that overloads all the basic math ops with a structure containing the computations of the value, the gradient, and the hessian. The trick, if there is any, is to have the basic AD variables store gradient vectors with a “1” in a unique spot for each separate variable. (And a zero elsewhere). Hessians of these essential variables are zero matrices. Mathematical combinations of the AD variables automatically accrue the gradient and hessian of ...whatever the expression is. Lagrange multipliers are AD variables which extend the size of your gradient. Oh, and each “point” in, say 3D, is actually 3 variables so your space (and size of gradient) is 3N + number is constraints in size. Write a newton solver and you are off and running.

This would be pretty hefty (Expensive) for a mesh. I’ve used it successfully for splines where a smaller set of control points controls a surface. Mesh direct sounds expensive to me. I assume you looked at constrained mesh smoothers? (E.g. old stuff like transfinite interpolation, Laplacian smoothing, etc?). Maybe newer stuff in discrete differential geometry can extend some of those old capabilities? What is the state of the art? I have a general impression the field “went another way” but not sure what that way is.

As for the auto diff, I’ve also got a version that does reverse mode via expression trees, but the fwd mode has been fast enough so far and is very simple. Nice thing here is that overloading can be used to construct the expression tree.

Of course if you do only gradient optimization you may not need the hessian. It’s there for Newton’s method.
Not really. Both are correct, and paradox fits better in OPs context,

Semiconductor process waste is a real problem (I used to work in an office where the old Fairchild Semiconductor plant had been, which I was told was the first Superfund site, though it wasn't) but it's actually a very manageable problem. It isn't inherent to the process in the way that CO₂ emission is inherent to burning coal, smelting steel, or making concrete, and it's orders of magnitude better than it used to be.

"public" is not the right concept here I think. E.g. imagine a composer conducting a public airing of some work of music (e.g. on some festival). That you were able to hear the music in public doesn't mean the {composer,artists,...} give up their copyrights.
Wasn't the point that they were scraping public profiles, i.e. they never signed up and thereby never signed any ToS?
I remember my dad being fed up with me asking "hey dad, can I play Woffenstone?" (yes, I pronounced it like that since I was a 11 year old kid from sweden back then) so he gave me the DOS 5.0 manual and said "here you go kiddo, you can play as much as you want when you've learned how to start the game by yourself).

That's where it all started for me and I was always on the computer whenever I could until my dad got fed up with me installing games and uninstalling his stuff so he password locked it in the BIOS.

So I had to figure out how to bypass the BIOS password which I eventually did by just guessing the password. Now I could play games and mess around on the computer whenever he wasn't at home but I had to hide all my games so that he didn't realize that I was using the computer whenever he wasn't at home. Eventually he did realize that so he changed the password and uninstalled all my games so once again I had to guess the password and this time I put my own BIOS password on it and all hell broke loose.

And that's where the hacker mentality started and sooner than later my dad bought a new computer and gave the old one to me.

Good times.

I'm not at all disagreeing. The coal phase-out should have happened a) before the nuclear phase-out and b) decades earlier. Processes like these tend to be pretty sluggish, the political discussions for both date back to the 1970s.

The actual health problems were negligible, but this isn't how politics work.
