Ceiling heights of 7 feet? Are you sure? Many tall people would only just fit upright...


7' is accurate for many new Housing Estate houses eg AV Jennings. The buildings all look similar except for roof color. It's very disorientating.

My house is 1860s with a 12' ceiling. Those other places feel like claustrophobic rabbit holes in comparison.

Low ceilings minimize material costs and maximize profits.


This is exactly right - it is done to reduce the building cost.

Of course having a ceiling this low is terrible for natural cooling so you then have to run air conditioning all the time costing far more in the long run. I live in a 1920s building with 11’ ceilings and I don’t have or need air conditioning because the place stays cool enough even through the height of summer.


most places in the UK don't run AC even during the summer.


> Low ceilings minimize material costs and maximize profits.

They also minimise heat loss, which is strictly regulated in the UK. Hence that other annoying feature of many modern build - tiny windows.


Why is heat loss regulated? Shouldn't I be able to heat my home as much or as little as I want?


The regulation is about energy efficiency of new-build construction, not how much you have your heating on. Partly it's a green thing, partly it's pragmatic, in that the UK has failed to invest in serious power generation for decades and faces the real possibility of brownouts in the not too distant future.

Plants are approaching EOL and they haven't been building new capacity to replace them. They've thrown a bunch of money at wind, but I think that's been more of a handout to (traditionally Conservative-voting) landowners than a viable strategy.


UK STILL don't fixed those issues?

UK since middle ages was already infamous for having cities (specially london, but not just london) that have energetic problems and rely a lot on coal (and now other fossil fuels), leading to the infamous killer fogs, and to the victorian fashion (in victorian era, people tried to use stuff that would not have issues in a highly polluted air, for example extremely thick and dark curtains, so that people don't notice you aren't washing them a lot...)


Across Europe there are strict standards for building efficiency. This is not just about insufficient infrastructure, it's to keep energy waste in check. People want as cheap a house as possible (which I understand, it's hugely expensive and most people have to make serious sacrifices) and when having to choose between not terribly energy-inefficient and full-height bedrooms, they'll often choose the latter. Which is unsustainable in the aggregate. Hence, tight regulations on energy efficiency.


> Which is unsustainable in the aggregate.

Isn't that just implying that most energy is artificially cheap, relative to its externalities?

Why can I own two new homes with 8' ceilings and heat them both(even if I don't live at one for 90% of the time), but I can't own one new home with 12' ceilings?


"Isn't that just implying that most energy is artificially cheap, relative to its externalities?"

Yes it is. But if you're going to charge 'real' price (even assuming you can), people with the least disposable income will have to pay disproportionally more for their energy, which is a a basic need in 2015. Plus it would cause ripple effects that are impossible to predict. So the prudent way of mitigating this is with targeted policies, like building efficiency. It's a political decision. Of course one might say 'we should charge everything at the full rate and let the market sort it out', which is a fine position (one I personally lean towards, for as much as that matters) but it's irrelevant to the fact that there are many groups that don't agree. So what we have now is a system with many groups pushing in various directions, and 'patches' for situations where that causes unwanted effects that all parties can agree on (well, a majority can agree on) should be mitigated somehow.

"Why can I own two new homes with 8' ceilings and heat them both(even if I don't live at one for 90% of the time), but I can't own one new home with 12' ceilings?"

So to come back to the issue at hand, I can also buy a 10MW heater, put it outside in my garden and have it 'waste' energy 24/7. We don't have laws against that (afaik). But our policies rely partly on the assumption of economically rational actors, which to a degree and in the aggregate is the empirically verified reality.

In other words, for ever policy I'm sure one can think of 100 ways to stay within the law yet violate the spirit of the policy. That's just the nature of governance, and it works fine in the vast majority of cases. Law is not a closed rule-based system like computers are, and that's fine.

(actually that last part is up for debate; even Montesquieu (who was the guy to come up with the original theory of 'balance of three powers') was of the opinion that perfect law should be just that, and that judges should do nothing but apply rigid rules to facts. But that's getting way more off topic than is reasonable...)


It's a the result of new of building code, which has minimum energy efficiency requirements. Residential energy efficiency is projected via heat loss calculations among other things.


Not when your country imports oil and you have a negative impact on its trade deficit (and/or environment).


Shouldn't I be regulated as to when I can open my windows then too? (as in, not in winter)


Well, "should" or "shouldn't" can get too complex to analyze.

There's no god given set of rights -- what we get to do is what the era/society/legal system we live in allows us.

And what's moral/good to do even outside or against what's allowed, is a matter of philosophy.

People expected to be able to smoke even on an airplane in the 70s. Nowadays not so much. Asking someone not to smoke "within 30 ft of this building's entrance" (a common sign), would seem as ridiculous to them as the regulation of heating to you.


The difference being that I don't pay a tax to the people who are inconvenienced when I smoke. Suppose everyone in an area set a price that they would be willing to smell cigarette smoke during their meal. If I pay them all that price, why shouldn't I be allowed to smoke? And some people would set it at +infinity, which is fine too, which would mean I don't get to smoke.

With heating, the government is placing a +infinity price on heat retention for buildings(with ceilings > 8'), but isn't actually enforcing that price in any other manner. Why not just charge progressively increasing amounts for electricity/gas expenditure? Right now, I can have a 100% legal, heat-efficient home, and heat it day and night by leaving the windows open. I wouldn't do that because I don't like to waste money, but that is just like I would not live in a house that was extremely energy inefficient.

Basically, if I want to pay for tall ceilings in my house, shouldn't I be able to, assuming I pay the appropriate amount?


>With heating, the government is placing a +infinity price on heat retention for buildings(with ceilings > 8'), but isn't actually enforcing that price in any other manner. Why not just charge progressively increasing amounts for electricity/gas expenditure?

Because they just want to impose a rule for what they believe is better for the environment.

They don't want to make it into a market product.

>Basically, if I want to pay for tall ceilings in my house, shouldn't I be able to, assuming I pay the appropriate amount?

That just makes it into something the rich can do while the poor can't. While indeed it also servers to lower the number of people doing't it -- it's not what any society that holds to high esteem any values besides net worth would want to do.

And I'm not just talking about the "tall ceilings" thing here, which might or might not be reasonable, but the more general question "shouldn't I pollute/waste as much energy as I want if I pay enough for it?".

Somethings we don't allow people to do at any price. Like kill people. Even if the victim also agrees. I, for one, don't believe payment trumps any morals in principle, and I wouldn't want that to be the case.

Whether it happens in practice (e.g. bribery etc), that's OK. But I wouldn't design a system where that's accepted and celebrated too.


Mate, this is bloody Oz. It hit nearly 46C (114F) last year in my city. Last thing I'm trying to do is minimize heat loss.


UK tenements had few or no windows due to the perverse tax formula.


Yep it totally claustrophobic if you are over 5’ in height. I really, really hate low ceilings.


Huh, I grew up in a house with ceilings no higher than maybe 7'2" (though that was not usual for buildings) and am 5'11" and wouldn't dream of calling it "claustrophobic". My father is even a couple inches taller. I guess it depends a lot on what you're used to.

Meanwhile my current residence has ceilings so high that I haven't bothered to install some LED bulbs that I have lying around since I don't have an easy safe way to reach the light fixtures.


I am sure different people feel differently, but for me low ceilings are a non-option. In a climate like mine high ceilings avoid the need for air conditioning.

You can get special poles for changing high bulbs. I have seen them before, but I can't remember what they are called.


Ah you must mean the good old "ceiling puncher". :)

Actually I think the pole is just the regular extension pole you'd use with a paint roller. You get a light bulb changing attachment instead.


Statistician here with experience in the financial world: you're wrong. Don't confuse the existence of Wikipedia pages and books written by people wanting to make money with actual science.

Moving averages have a function in statistics. But there is no evidence that they can be used to time the markets. If they could, it would be done algorithmically by hedge funds, closing the possibility.

Please show actual analysis of market data (i.e. recent published scientific papers) supporting your positions. Without those, it's quackery.


I've been working in hedge funds for over a decade, and it's interesting what the variety of opinions is. There's a great deal of secrecy, and good reasons for it, so getting to know how other quants do things has been quite informative.

On the one hand, your arbitrage argument makes sense. If there existed a simple strategy that made money, it would be traded out of existence.

On the other hand, I happen to know how the major quantitative funds allocate their money. It is a simple formula, with a number of small twists. (Yes, people will not believe you if you claim this. Rightly so.)

Now, how can these facts coexist? The answer is that the formula "sort of works". There are long periods where it doesn't work, and periods where the returns are phenomenal. If someone were to start a new fund, they would have a number of issues:

- It is just not quite believable that such a simple formula is profitable. What are those hordes of phds actually doing? (Squeezing a lemon actually). Surely someone else would have found it?

- Institutional investors have all sorts of issues with investing. It's done by committee. They need you to have a long track record. They want all the right boxes checked.

- What happens if you launch and you start with a fallow period?

- Even if a simple formula works, why does it work? Are you happy to trade something that you don't really understand?


I've been on the hedge fund algo side for years. You're spot on and it's what a lot of these guys on this thread are clueless about.

Basic or simple approaches can be combined with others and be statistically/mathematically sound and robust.

Some work for periods of time, some don't, some stop working. Algorithms degrade over time and that's continued optimization is a must.

Case and point: LTCM and the story behind black scholes algo running up against a black swan.

I'd highly recommend watching this for the others reading this thread that really just are familiar with the whole space:

> black scholes algo

Black Scholes isn't an "algo". Sweet mother of god...


No need in explaining the difference between an algorithm that wraps around an equation or to call an equation a "model" or to call a model a "formula". Take your pick but focus on the meat of the discussion if possible.


Hedge fund algorithm developer here. You misread:

1. The existence of mathematica was quoted first.

2. Moving averages are a "lagging indicator", which I stated, not a predictive indicator which I did not state.

3. I develop hedge fund algorithms.

References to papers include this most important one: "Contagious Speculation and a Cure for Cancer: A Non-Event that Made Stock Prices Soar," https://www0.gsb.columbia.edu/faculty/ghuberman/research.htm...


> 3. I develop hedge fund algorithms.

Do the hedge funds know? ;P


Our bank accounts do.


Until they don't. As a group, hedge funds far underperform index funds.


Algorithms degrade, we optimize. We're in the top 25. They last longer than more full time jobs.


Presumably the advantage of this over a standard filter is that blocking (hopefully!) checks SPF/DKIM and verifies that the person being blocked is actually the sender of the email. Simply blocking a From-address would not be effective.


(Heavy metal or other) contamination of the drugs you receive could be an issue. Who's testing the India-/China-produced drug?

You might receive an Official batch that may or may not be checked by their local governments, but it might also be from a more shady source.


If you got paid as an employee to build the app, his position isn't as weird as it seems (ignoring verbal promises). After all, he had already borne most of the risk at that point.


Source for the 0.8% for local bank card payment? Last I read it was a fixed 4-6 cents per payment. See [1], for example.

[1] https://www.abnamro.nl/nl/zakelijk/betalen/tarieven/sepa-bet...


Given that a huge number of transactions will be near 1-2 euros, the average cost in terms of percent could really be 0.8%. Not that I've seen the numbers mind you.


I too use Gandi, but am not as happy as I used to be with them.

I bought a domain from them a while back with private registration; a few weeks later I found out that private registration was not available for that TLD, and my details were publicly visible, making the domain unusable to me. I emailed Gandi, and they told me there was nothing they could do; they were not willing to refund my money, even though their site said private whois was possible for that TLD.


Hi, AJ from Gandi here. Do you have the ticket number from the subject line of the support email? If we made a mistake like that, we should make it right.


Please see #4837764.


Thanks. I just looked at your situation, and you're right, that was our mistake. I took action and replied to your ticket with details; hope that helps.


Thank you!


I have some questions about the legality: Since the miners mine this contract (or include it in the blockchain, or whatever it is for Ether), does that make them violate the UIGEA [1] or other gambling laws? And since the OP lives in NY, does creating & posting this violate, for example, "promotion of gambling"-laws? [2]

I think this would be illegal. Could this be considered a raffle?


You speak about "Europe" like it's a country with a single set of regulations. It's not-- it's a continent. Even for the European Union, the rules are actually extremely varied:

http://www.worker-participation.eu/National-Industrial-Relat...

And even those countries with councils have (as the link also mentions) very varying rules on exactly what the councils do. Please don't say "Europe" when you mean "some European country".


so Germany has not taken over all of Europia? color me surprised.

oder aber du checker überlegst mal, für wen die simplifizierung 'Europa' gedacht war.
