Imagine how much more they could save by keeping the heated mattress pad on and never leave the bed! I mostly jest..

The author seems totally unaware of the efficiency gains that a heat pump can provide. A 300W space heater will be easily outmatched by a heat pump that consumes 300W (unless we're dropping way, way below 0C). The efficiency is likely ~3x [1]. I hope the author isn't making this mistake out of disdain for centralized hvac, since window unit heat pumps are readily available for small spaces.

Define the "natural" state of affairs. Is literacy part of this "natural" state? How about real time communication across thousands of miles?

It's a lot more constructive to talk about a desirable state of affairs. And this in my mind includes easy access to information.
Isn't he aware that the device neutrality terms (which BTW i don't see as relevant, but he brought them up) dont apply to 4G unlimited plans grandfathered in after a settlement with the.. FCC? New plans have to allow tethering, grandfathered unlimited plans, under the terms of the settlement, don't. However, maybe unlimited plans that aren't on contract aren't covered by the settlement?
An interesting approach - though for contrast, a well built passivhaus or low exergy design can achieve similar savings or even net positive. At a cost, true, but at much greater convenience. I feel having to do this is basically admitting that our houses are terribly engineered. And yes, with this kind of system you get problems with damp and mold which can have some pretty serious health impacts.

I see this as one of the fundamental problems with the AGPL/Apache licensing patterns. The company can create an Apache driver, but it's not clear when a member of the community creates a driver if they can also use the Apache license. If all they do is present the driver, then presumably yes, but if they publish a service using their driver calling the AGPL licensed code, their driver should be subject to AGPL's terms which would apply the AGPL to it.

Alternatively they could assign the copyright of their code to a company? But why would they be motivated to do so?

This creates an asymmetry of rights where the company can do things that community members cannot. This seems to the very opposite of what the Open Source movement has been all about.

> > Then you use insulation. This especially is something that feels nobody in the US has heard of. At least in California.

There's lots of poorly insulated homes in California, either because they are old or cheaply-made, or because they are in places that have milder weather where it is less necessary. But there are also lots of well-insulated homes in California.

> In defense of Californians, most of us rarely, if ever, turn on a heater and most homes here don't have AC. Our heating and cooling costs are a small fraction of those of you who live in places that have seasons.

As a Central Valley resident, I think you may be falsely generalizing from "the Bay Area" to "California". Even cheap homes in the Valley usually have AC, even if its not central AC.

In Denmark it's getting pretty common to produce it via trash incinerators. They produce a kind of heat that is apparently that not great for electricity generation, but pretty good for district-heat production. So much so that the price of unsorted municipal garbage in both Denmark and Sweden has risen in the past few years, because it has become a valuable energy source.

As I said, laptops don't have the e-ink resolution. And depending on what you read, it might not even have the same contrast.

So, unless you adjust the brightness and contrast appropriately and have a hi-DPI laptop, e-ink will come on top for reading. There's also the convenience in holding the reader vs using the laptop to read.

So cannot really compare it to a common laptop. To actually compare like to like, compare an e-ink reader with a hi-dpi ("retina") tablet, with the brightness/contrast configured appropriately.
"most homes here don't have AC."

That really depends on where in the state you are. Coastal cities, generally, more so. Inland, even within the SF Bay Area or Los Angeles, you'll find a lot of AC, and in the Central Valley it's a huge determinant of load and peak load.

Then why on earth was I freezing my balls off in Menlo Park this November? The weeks before we realised our house even had heating were miserable. And even afterwards, as soon as the heaters weren't blowing hot air, or you were more than 3ft away, you were instantly cold and miserable.
The Curious Evolution of Artificial Life
Dehumidifiers are reasonably efficient, and in a cold-weather climate, the waste heat is actually a bonus as it contributes to interior heating.
Energy is abundant, there is no need to shiver in the cold. Solar forced warm air is inexpensive, simple technology that is very underutilized.

Solar photovoltaics get all the attention, but solar warm air/water is less expensive and simple to manufacture.

Why not make a housing sandwich? (of sorts)

Like this:

It costs a bit of land, but the area would be much nicer.
My 2 bed apartment, with both people working from home pretty regularly, and floor-to-ceiling windows on one side, costs < $30/mo for electric + gas except for 2-3 months in the winter, when it rises to $60 or so. Though we have no tv and no a/c. (last bill: 5.8 kWh/day)

Given those costs, it's very difficult to get a return on better insulation or insulated windows.
I'm thinking of a cross between these two iphone apps:

Well, FWIW, I for one can read a whole books, actually lots of them from both iBooks and iOS's Kindle app (read on a tablet. Heck, even on an iPhone). And don't care particularly for e-ink (I also have a kindle I don't use much).

If you can find some specific scientific argument why e-ink is "an essential requirement" (besides personal choice) then it's just cargo cult.

I listed fairly accurately were e-ink is better, namely reading in sunlight. And battery life, which I forgot.

For reading inside, it's advantages of yore, like resolution have been matched by hi-dpi screens. The only other advantage is better default contrast, which is a configurable setting on a tablet.

That can help you make more efficient use of bandwidth and TX power, but doesn't come anywhere near making a free-for-all spectrum workable.

The carrying capacity for wireless customers (and carriers) could increase to above where it is now, but not the point where frequency coordination is unnecessary.
I don't think it's about resolution. I'm comparing a 15'' 1920x1080 laptop screen to my 2nd Gen Kindle. I think it's about brightness. Light-emitting screens make it harder on the eyes to read books. An iPad's screen feels similarly uncomfortable to me. The main benefit of e-ink is that it doesn't emit light and therefore feels almost like a paper book.

Agreed about the ergonomics: it's more comfortable to hold a kindle than a laptop. However, I'm not sure I could replicate the experience with a tablet: I'd have to lower brightness a lot, increase contrast, and shine a light on it, at which point LCDs stop being comfortable to read.

You're correct about users not hovering over exactly where they are reading in order not to block their view with the cursor, but studies have shown that people do position their cursor very close to or just below where they are actually reading (there are, however, also other usage patterns such as the scroller who simply leaves his cursor in one place and scrolls down the page).

We've allowed users to create links to their projects in order to make would normally be non-interactive text blocks on a resume into something clickable.

> The powers that caused this privacy apocalypse in order to profit

Wow, such loaded terminology. Those "powers" are literally nothing more than the logical and direct evolution of digital information technology. You can point fingers at some company or technologist or other, but those are incidental actors amongst a much larger sea change in how information is stored, copied, and transmitted.

Just a very few years ago, the potential ramifications of these changes weren't really apparent to anyone. We're only just now coming to grips with it and like all periods of social change, it's not really clear how to proceed. There are significant and valid questions to be grappled with: if someone has a "right to be forgotten", what other rights and concerns must be balanced against that? Who holds responsibility for this "forgetting"? Google argues that it's unjust for it to shoulder this burden. They may be right -- this problem has so far been tackled by one branch of government in one world jurisdiction. Historically speaking, I think it unlikely this one case will be a full and fair treatment of the issue.

> without having to pay for armies of lawyers.

It may be that we've built infrastructure that makes other alternatives, all factors considered (including, but not just the rights of those who've "paid their debts"), not merely inconvenient but impossible in practice. This doesn't even mean that there may not be solutions, but that this approach to modern issues of privacy is a dead end.
Irrelevant for some TLDs that don't show the world your domain expiry date.

Not only that, but why is it reasonable to remove the choice of privacy? That's the part that concerns me the most about these discussions, is the way "the internet" should either be all one way, or the complete opposite. That will never be realistic and I feel we should be focusing on the balancing act that works the best for the majority of use-cases.

"Many very smart people who know far more than I do about Woz, Jobs, and Silicon Valley give the highest praise to Jobs."

I believe they do so because they're praising the wrong thing. Making money for investors is not all that good of an end in and of itself.

Clearly, this is subjective. But, I don't consider Jobs to have been particularly good for the world, despite his many obvious talents at directing the making and marketing of popular products. I have a quite strong anti-Apple bias, based on my belief that Apple has dragged the tech industry backward rather than forward in terms of providing more access to technology education and more access to the technology economy to more people, particularly the poorest people. Just when Open Source was pushing the world toward freely available source code for everything (and succeeding), Apple's App Store was slicing up the pie, with proprietary software effectively being required to participate (locking out all but the relatively wealthy from participating), and serving the biggest piece of that pie to themselves.

But, that's just my opinion. Many people think Jobs was great, and that Apple is good rather than a negative force.

OK, Paul Wheaton simply doesn't know what he's talking about:

"I think that this does produce some savings, but not as much as you might think. If you set your thermostat to a constant 70, the heater works a little at a time throughout the day. If you drop it to 50 at night or in the middle of the day, the heater stops working, but then when the time comes to warm the house again, the heater has to work at full power for a long time to get the temp back up - thus losing a lot of your savings."

WRONG WRONG WRONG WRONG WRONG WRONG WRONG WRONG WRONG

Heat losses are driven by two factors:

1. The temperature differential between the hot and cold sides.

2. The thermal conductivity (or exchange) between the hot and cold sides.

That's straight out of Newton's Law of Cooling / Fourier's Law:

http://en.wikipedia.org/wiki/Convective_heat_transfer#Newton...

If you're running heat constantly, you're maintaining a constant flow of heat from your interior to the exterior. That is, you're maintaining a high heat exchange rate to the exterior, and you're constantly wasting a large portion of heat.

If you're heating only while you need a warm interior, then as the interior temperature falls, the energy flux to the exterior decreases. You're no longer pumping heat into the external environment.

Yes, you'll run your furnace/heating system continuously for a while in raising the interior temperature, but that is largely adding heat to the interior space, not to the exterior.

The net is expending less energy.

Your most efficient strategy is to turn interior heat down to the minimum essential level (ultimately: enough to keep pipes from freezing), or the minimum level the thermostat allows (often ~50F in the US). My own practice is generally to turn any heating system off entirely at night.

From a moisture management perspective, you also win as cold air has a lower absolute humidity, that is, the quantity of water it can hold is lower. Heating cold humid air reduces the relative humidity, allowing walls and surfaces to dry out.

The overnight heat loss is also a very clear sign that Paul Wheaton is dealing with an exceptionally poorly insulated structure. And a very poor grasp of thermodynamics.

The same principle holds for AC as well, though here you want to increase the temperature setting at which the AC comes on, or disable AC entirely while you're out of the home.

A better way of thinking of this is to minimize the energy input (heating or cooling) when it's not needed.

Your point about fixtures and heat losses through ceilings are actually well-taken. Recessed "can" lighting is actually a huge pathway for heat loss two ways:

1. The radiant heat from bulbs which is transferred into the ceiling and attic spaces, rather than the living space.

2. Other heat flow losses, including often very significant airflow, through the lighting fixtures. Thorsten Chlupp (mentioned elsewhere) includes lighting fixtures among his anti-penetration measures. He also keeps his wiring and plumbing runways along the inner insulates spaces, rather than outside the thermal barrier (with concomitant envelope penetrations).
