CRI is next to b.s. by itself, without further qualification. This is how we get craptastic lights where socks mismatch under a CRI 90+ light but not under daylight. The whole point of CRI is to try to turn a complex evaluation into a simple one, and encourages ignoring the dirty filthy truth about certain kinds of light sources, i.e. its emission lines. If you compare the spectral power distribution of incandescent and daylight (sun light on earth filtered through the atmosphere) they don't look anything alike except that both are very smooth spectra.

Whereas LED and fluorescent have very spikey spectra. We tend to not notice these spikes, but sometimes, depending on their location and depending on the materials being viewed under such a light source, they can have a pronounced effect that isn't predicted by CRI.

CRI has been a pretty hot potato for some time with a lot of scientists trying to fix it, butting up against a lighting industry that doesn't give a flying crap about accurate color reproduction, they just want a high number CRI so they can sell their shitty lights.
> The clinical white beam of LEDs and frustrating time-delay of ‘green’ lighting has left many hankering after the instant, bright warm glow of traditional filament bulbs.

Sheer garbage. LEDs come on instantly, and are available in various color temperatures, thanks to filtering: you can have then in 2700K. If your LED isn't coming on instantly, it has some problem with the power supply, probably because you bought the lowest bargain-bin crap you could get your hands on.

I've had Phillips flood lights (3000K) in my kitchen and living room for several years. They come on instantly and put out a warmly colored light that is consistent from the center of the spot to the fringes.
Indeed it is, but that doesn't mean anything illuminated by a blackbody "match the hue of objects seen in natural daylight." CRI has much more to do with the ability to discriminate colors. The absolute hue is a strong function of the color temperature of the illumination, but the eye/brain is also very good at normalizing that away.

This is precisely why I don't think people complaining about "nasty cool light" are based in fact. The color of the environment around you will quickly be normalized to be neutral by your brain, and it will be impossible for you to tell whether you are illuminated by a 3000K or 5500K light. You can really only tell color differences accurately.

I hear a lot about the "delays" in incandescent alternatives, but all of mine are barely perceptible. My Flux bulb has like 400ms; it's palpable but how could it ever annoy me? How often were you trying to illuminate something with a light bulb within 400ms and missed it?

And of course, many of the adjustable/smart LEDs can mimic incandescent light temperature with ease. They cost more, but not necessarily over their lifetime.

As mentioned, this article was fluff.
Can those be used on arbitrary devices? If they are now, will they always be? Does this solve the initial problem anyway?

> Is that really true? I can't imagine a recruiter asking about Haskell, or a Facebook-sized company talking about their OCaml strategy, ten years ago.

I think it may have risen a tiny bit but here's why I think it appears larger than it is: I don't think a recruiter would ask about Haskell today outside a very small section of the ecosystem, but that section seems just larger than it is. What has changed in the past 20 years is the cultural prominence of the startup culture (SV startups hardly make up a minuscule percentage of the software industry, yet they get a significant portion of the media coverage), and even then only if you're involved in communities like Reddit and HN.

I think it is more an artifact of those communities that using certain languages lends a certain prestige, which is then used as a marketing effort (the CTO of a well known SV startup once told me that they have a small team using Scala only so they could attract a certain crowd). Similarly, in Facebook, it is my understanding that Haskell isn't really spreading, but is more of a marketing gimmick to developers of a certain sort in an environment with very unique characteristics. The entire software development industry consists of, I'd make an educated guess, 20 million developers or more (extrapolating from the known number of ~10M Java developers). I would be immensely surprised if more than a million of them can tell you what Haskell is (and by that I mean "a pure functional language").

So there's definitely an uptick in numbers and a rather strong uptick in exposure -- assuming you're following the right online communities -- but I don't think there's a real uptick in portion of production systems. Some people used Lisp and ML in production 20 years ago, too. They just didn't have HN to tell everyone about it. I'm not even sure we're currently at '80s level. Haskell is certainly talked about and used less than Smalltalk in the '80s, and see where it is today.

What is definitely true that some ideas that had previously been associated with functional programming, most notably higher-order functions, have now finally made it into nearly all mainstream languages.

> That feels like gerrymandering your definitions to me. GC is usually a language-level feature.

I think the distinction between language-level abstractions and something like a GC (or dynamic linking) is rather clear, but I won't insist.

> How would we tell? The productivity of the technology industry as a whole has certainly risen enormously. My general impression is that coding is the bottleneck a lot less often - even for a technology company - than it was five or ten years ago.

Is it? I've been a professional developer for 20 years and while I agree that productivity has gone up considerably (maybe 2-3x) it can be attributed nearly entirely to automated tests and GCs.

This isn't wrong, assuming that you can get the real stuff. Extra virgin olive oil (EVOO) has a higher smoke point and will survive cooking. Unfortunately, if you purchase olive oil in the US, there's a good chance that it's been processed, even if the label claims it's EVOO! A study by UC Davis found that 2/3 of oils labeled EVOO did NOT meet the standards.

The processing step that the fake oils use will degrade the antioxidant capacity that you'd get from real, cold-pressed oil.

So, in summary:

PUFA's go rancid easily in absence of antioxidants.

Pure EVOO, though PUFA, has antioxidants that protect it.

If you buy "EVOO" in the US, it has possibly undergone processing (despite the label!), which means that it will have lower antioxidative capacity

It can double the gadgets, but it doesn't necessarily have to. If the reduction in total income leads to less demand for (other people's) labor, then people could just work less in total and consume the same. They're better off, but have the same GDP.

Alternatively, imagine that someone makes a universal bot-slave that provides for all of your needs, manufacturing as necessary from raw inputs. It just buys the natural resources for pennies and makes them for you. The only inter-human commerce is for the natural resources (delegated through the bot-slave).

In that case, almost none of the production shows up in GDP accounting (because the bot just makes it and gives it to you), yet people are much better off.

Doesn't work out when heating wouldn't be used, or AC would be.

Heating isn't always electric.

Using electricity for heating is an egregious waste of a high quality energy source which can do all sorts of useful things besides generating heat.
This news article doesn't even mention the article's name, the authors, or when it was published.

It was actually published in January, and has just now been picked up by the Telegraph.

Here is the citation:

Ognjen Ilic, Peter Bermel, Gang Chen, John D. Joannopoulos, Ivan
Celanovic, Marin Soljačić. Tailoring high-temperature radiation and
the resurrection of the incandescent source. Nature Nanotechnology,
2016; DOI: 10.1038/nnano.2015.309

And here is the actual paper, via Sci-Hub: http://sci-hub.cc/10.1038/nnano.2015.309

The Telegraph's explanation is terrible: "with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through."

The tungsten filament is sandwiched between two plates made up of layers of oxides, designed to selectively reflect infrared radiation and transmit visible light.

They used a numerical model to design and evaluate various candidate compositions for these plates. For a proof-of-concept, they chose one which uses layers of silicon oxide and tantalum oxide, with 90 layers in total per plate. This reflected about 90% of infrared radiation, producing a luminous efficiency of about 6.6%. This is comparable to commercial LEDs and compact fluorescents, though far from state-of-the-art.

However, the results closely matched their numerical model, and a more complex structure comprised of layers of silicon dioxide, aluminium oxide, tantalum oxide and titanium dioxide, with 300 layers in total, should produce a luminous efficiency of 40%. This is significantly better than the state-of-the-art in LEDs (about 15-30%). They did not, however, actually build that one.

I have no idea how expensive this would be to commercialise. It doesn't sound like the physics is particularly complex, but manufacturing costs could be prohibitive. I think it's safe to say we won't be seeing it outside the laboratory any time soon.
Direct electric is a really inefficient way of heating anything. I ripped out a direct electric heater system and replaced it with a ground source heat pump which is giving 4KW heat for every 1KW electricity (used to run the pump and compressor etc) even in the cold depths of the Swedish winter.
It's a bit more complex. The licensing restriction is really just a restriction that data you mix with OSM data also needs to be ODbL, because other data under ODbL can't be incorporated back into OSM. Mixing two geodata sets is a pretty common thing to do, but you can't do that as easily with OSM data because of ODbL (I think it has something to do with the crediting).

Some companies have been interested in using and contributing back to OSM data, but didn't go further, because of the license.

Why do you think a fork that lacks the advantage of a free license can become a threat to the continued existence of a project?
At least in the Middle Ages, there were algorithms that reigned over the king. A king had an executive role (comparable to a US president, greater than a parliamentary prime minister), but was constrained by customary law -- which is fancy-speak for "the way we've always done things," but even so, it meant there were things a king couldn't do. One of the issues Barbara Tuchman mentions in _A Distant Mirror_ is the way in which the French king could only levy a tax on the whole realm when at war, and even then couldn't continue it after the war ended -- the expectation being that "the king will live of his own," i.e. support himself from his personal estates, at peace.

Going forward in history, that's why the Carlists in 19th-century Spain were both pro-autocracy and fighting for their liberties: they preferred a king who was the absolute monarch of a half-dozen countries (Castile, Leon, Navarre, Galicia, Aragon, and Andalusia), instead of a centralized federal government in which none of the kingdoms had special privileges (note that Carlism was strongest in the northern parts of Spain) and all kingdoms' subjects were administered impartially from Madrid.

Anecdote time. Those evil flourescent bulbs have made my life miserable.

They don't last substantially longer in the real world. I am routinely replacing them within 12 months.

They cost an order of magnitude more.

They are considered toxic waste with special clean-up and disposal considerations.

The amount of energy they save as a fraction of my total electric bill is inconsequential.

> I never write JS > ECMAScript 5. Why?

That's a bold statement. Why EcmaScript 5 and not JavaScript 1.4 for that matter?

Programming languages change and evolve. EcmaScript 6 introduces a lot of features, including some that greatly improve the readability, maintainability, and cleanliness of the code. Sure, right now you may need to hold back on some features if supporting legacy Internet Explorer versions is your goal and you don't use a preprocessor such as BabelJs, but at some point the only browsers that don't support ES6 will be browsers that are unsupported by their vendors and inherently unsafe; so why stick with ES5 in particular? Or are you simply waiting for the moment all current browsers support ES6?

I get not wanting to use bleeding edge features supported only in the latest developer edition of Chrome or Firefox, but at some point ES6 is supported in 100% of the browsers people can safely use, and a few years after that ES7, and so on.
Of course, the bulbs would add 97% waste heat if heat isn't wanted. But most places here in the US have some soft of heating system for the winter. That would pretty much require changing out the bulbs for the winter.

I never said that incandescents would eliminate heating, only that it is 100% efficient when used appropriately.
Right. Households often have multiple incomes. That doesn't help the OP's point, though, since people in Ohio are more likely to live in a multi-income household than people in California.

If you look at per capita income instead of household, Ohio gives $135,500/$26,937 ~= 5, and California gives $405,000/$30,441 = 13 By that standard, California is 2.6 times more expensive instead of only 2.

Indeed. I recently replaced all the incandescent cans in my house with LED cans and was very certain to specify a color temperature. I've also got "LED filament" bulbs in one room at 2200K (designed to replace those clear 'vintage' bulbs), which give a really cozy feel, if a little too yellow. Yet for my garage, I love the high color temperature bulbs.

bad reporting.
You could use the 97% of electricity that was lost to heat to power a heat pump. Heat pumps beat 100% efficiency. [1]

> In heating mode, heat pumps are three to four times more efficient in their use of electric power than simple electrical resistance heaters.

Instead of just generating waste heat, you generate waste heat and move heat around in a desired way.

I used to live in London (England) and walk and tube everywhere. My first trip to the US was LA. I parked at a cafe and bought a coffee. We saw a store across the street so crossed it. Even though traffic was light and it was easy to do so without causing it to slow down the cars honked us for doing so. Jaywalking. I'd never really thought of Jaywalking outside of movies.

So we go in the store and afterwards make an effort to walk a couple of blocks down to the crossing so we don't get arrested or run down. When we get back to the car there's a tow truck trying to take it away because we were shopping across the street and no longer customers of this strip.

It was pretty amazing to us. We spent the rest of the trip driving everywhere, no matter how small the journey.

I've looked at it before, in the context of R/C aircraft (my hobby). The problem is the same one everyone else has named: airplanes need to maximize power-to-weight ratio and hybrid-electric systems are heavier for a given power output.

My conclusion was that a battery-based system was a bad approach. Instead you would want to use a hybrid motor/generator approach - you can use a glow motor to spin an electric motor, and if you couple the electric motor to another identical motor they will spin lockstep. It's like a diesel-electric transmission on a ship or locomotive. And the funny thing is glow engines are actually a kind of diesel engine too.

https://youtu.be/6kgzrXFSDwA?t=13

This would be most advantageous for multi-engine setups because you would be able to use more energy-dense liquid fuels instead of batteries, use a single larger/more efficient motor as the prime mover, and avoid the complexity of multi-engine operation. With gas engines, you need to tune each engine to perform similarly, have a throttle servo with identical/aligned travel for each, independent fuel supplies (or at least header tanks), etc. Whereas electric motors are dead simple, but the problem is the batteries are hard to lift. So instead of batteries you have a prime mover - and on top of that you get liquid fuels too.

Ideally you'd probably want a single larger generator-motor attached to multiple small drive motors, but they would need to be chosen so that the electrical characteristics of the motors were appropriate for each other throughout the RPM range.

The downside is that it probably doesn't scale well to full-size aircraft - many small aircraft are relatively underpowered even with gas engines. And in both cases, having multiple independent power sources enhances safety, as this creates a single point-of-failure.
Traditional incandescent lights have terrible efficiency 2.5% or so. The benefit from Old Incandescent vs LED's is huge (5x to 10+x), but there is just not much room from the best LED's to 100% efficiency making the remaining gains less important. https://en.wikipedia.org/wiki/Luminous_efficacy

PS: Power is kind of an odd thing. Direct costs are so cheap most people ignore it, but the external costs are high enough to push efficiency gains. Taxes would be the best solution, but politics is odd.
The utility tool has OSS equivalents but we've evaluated them all. None of them have the features we need, and adding them would be person-years of work we can't afford.

My hope is to some day open source our internal tool, but we have to wait until the OSS features we need catch up. Until then, we aren't willing to pay the high license fee to redistribute this utility freely.

I'm speaking a little cryptically because I'd rather not have this tied directly to any particular company (neither mine nor the one we license this code from). I'm not speaking on their behalves officially; only my own.
