Interestingly enough the GPU is approximately the same speed as the upcoming (or current?) generation of Android phones with the Snapdragon 800 SOC. In the past Apple has generally held a large performance advantage in that area. There is potential that in 6 months when the next Galaxy/HTC phones are released that they will be significantly ahead of Apple for 6 or more months.

Is it the phosphors that wear out? If so, many LED bulbs uses phosphors, make it also a form of fluorescence bulb.
I'm confused. The story talks about manufacturing and transport. However, I don't care about that.

As a consumer, I want to know $/lumen. That's it.

The last time I looked, the energy savings for LED were swamped by the upfront purchase costs. CFLs were still significantly cheaper.

Of course, that's for NZ, and the US might be different.

NZ Prices from Consumers NZ (Bulb + Running over 5 years)

Incandescent: $115
CFL: $30
LED: $95 (60W equiv), or $57 (40W equiv)
Got it, thanks for the clarification. But either way, the US looks pretty bad on this metric.
While it's far from a complete measure of performance, one data point is that the PS4 GPU is capable of 1.84 tflops, the 5s GPU is capable of 76.8 gflops, only ~4.2% the throughput of the PS4.
Agreed. Take the Machine Learning class on Coursera if you need an introduction to them.
No. In fact, the LED lifetime stated on the packaging is actually the time it takes to decrease in brightness to a specified reference level -- usually 70% of initial brightness.

Since it is solid-state, though, the LED is expected to continue operating long after it reaches 70% brightness. 70% is simply the assumed reference point at which the consumer becomes annoyed and decides to replace the LED.

> the Alliance for Solid State Illumination Systems and
Technologies (ASSIST), a group led by the Lighting Research Center (LRC), recommends defining useful life as the point at which light output has declined to 70% of initial lumens (abbreviated as L70) for general lighting and 50% (L50) for LEDs used for decorative purposes.
Look at it this way:

If electricity was cheaper than oil/gas, then you wouldn't use an oil/gas furnace to begin with.

So, an efficient lighting system is saving you money.
Yup, my house is heated using an electric furnace (resistive heat). Thus the heat from incandescent lightbulbs doesn't go to waste during the winter.
> one by Philips that gets 200 lumens/watt.

The absolute theoretical max for efficiency is 251 lumens/watt. I find it incredibly unlikely that they are going to reach 200 with white light.

What I think will happen is they'll get there by having a very low CRI, with off-color light. It's already happening in the market - all the high efficiency bulbs have a CRI of 80 (the minimum needed to get an Energy Star rating). But the CFLs they are compared against often have a CRI of 90.
You think the other presidential choice would have been better?

You really only have a choice between two identical assholes. There's no point in voting unless America drastically changes its voting system to something more democratic.
Adding a ppa introduces one more point of trust. That makes it not an easy option.
Even the new generation LED lamps are like that (Cree X and such)? I read something the other day that suggested these LEDs were immune to losing efficiency over time (the efficiency would be dictated only by heat).
Are there good CFL or LED bulbs with proper color temp? I end up using halogen bulbs in every room in my house because I've not been able to find anything that's remotely as nice.
Well yes, but the thermals are less of a battery when you don't have to worry about battery condition or battery usage.

But the guy with his family out in the cold on xmas because bigcorp decided they didn't need him after 39 years and he has no other marketable skill(of whose fault is debatable)? Yeah, I'm buying that family dinner. This kind of thinking, the "them vs us" instead of _US_ as a whole. This is what keeps divisions between us. This is how racism survives, this is how people don't care for the homeless, the poor, the sick, the people in 3rd world countries suffering to provide you your fancy 1st-world luxuries. Screw 'em, right? If they weren't smart(read: lucky) enough to be successful that's their own fault. What, they didn't know enough to learn fancypants.js in 2007? Too bad! What, they thought they should be working at the corp forever and getting a nice retirement package? Pfft, whatever! What are people suppose to do? EVERYONE can't be an entrepreneur. Some(apparently a lot) of people just want to do an honest day's work for an honest day's pay.
I'm glad that I know a good term for "false proxies" now. It seems to be a problem that comes up all the time in wildly different contexts. I sometimes call it "painting a banana yellow", but that doesn't necessarily convey the meaning to someone unless I've previously explained the analogy.
“This is why I wonder, to this day, why a coalition of entrepreneurs do not support a basic income. It is the ultimate hedge against failure in a capitalistic society, and would severely curtail the risks of failed ventures for every individual.”

Doesn’t that kind of sound like “privatize the gains, socialize the losses”? I don‘t really see how entrepreneurs would benefit overall from a basic income; successful individuals would have to pay for this through higher taxes, which would probably disincentivize risk-taking overall. Intuitively, it seems to me that any sort of scheme that tries to cheat the free market by subsidizing people who take risks and fail at the expense of those who either succeed or avoid risks probably overincentivizes risk-taking. Why should someone who doesn’t think their idea is good enough to put their own money at risk and can’t find anyone else who wants to invest and put their money at risk either get a taxpayer subsidy?

This makes especially little sense in Silicon Valley:
“OK, I quit my well-paying tech job with health insurance and free food because I thought I could successfully bootstrap the next big social media blogging platform with my entire life savings, and now I’m somehow unemployable, bankrupt, and homeless, I deserve a bailout!”

Obviously, there needs to be some amount of risk-taking, but I’m extremely doubtful that it makes sense in general for the government to subsidize starting tech companies, especially when there are so many willing private investors. I agree that having health insurance be largely the employer’s responsibility does complicate switching jobs and starting companies.
I assume his "basic level of support" was at least at, if not higher than, the USA-defined "poverty line" ... which is above 87% of world incomes (PPP adjusted). He wants others to, under implied or actual threat of gunpoint, be compelled to provide for what he considers basic needs (and much of the world considers luxury) with no consideration of impact on their lives. This because he chose a life of debt and rent, most likely in an area most others could not afford to live in. Am I wrong?
If you have not already and can do so, I highly recommend adding Dtrace to your C development toolkit. Dtrace, Valgrind, and GDB make rooting out C runtime issues a lot more pleasant and complement one another well.

The statement "cheap energy" is really hard to quantify (like 'largest integer') you can say "Gee Coal is really Cheap and there is tons and tons of it!" Except that coal smoke is killing people, contaminating large swaths of land etc. But at $100 a barrel you can gasify coal and make clean gas power plants cost effectively, but what is the $100 really mean? Its local currency (US Dollars) in a world economy. At a high enough price you can build nuclear plants and fast breeder reactors that eat all their own fuel. And use that energy to make long chain hydrocarbons (aka oil) out of CO2 and electrolisys of water [1]. Politically nonviable but that too is a system, what do people vote for energy and synthesize oil for plastics or a degenerating quality of life? There is some thoughts that you can run F-T reactors using concentrated solar in the desert.

But to you point of 'running out of cheap energy' what does that mean if the economy has adjusted to the cost of that energy? Look at electric cars as a prime example, sure they are expensive today but what happens 10 years from now when they are everywhere? Now $200/barrel oil, converted into electricity at a fossil fuel plant is give you the same miles per $ as burning it as gasoline used to do in your internal combustion engine.

Constant adaptation by the system to the constraints applied to it.

An investment thesis is basically a hypothesis about what sort of companies will do well as investments. Some investors don't have a specific thesis, and will invest in any company that looks good to them. Others have a specific take on the startup ecosystem. For example an investor might believe that infrastructure companies are a great bet going forward, or they might think that the sharing economy is the right bet, or, as in case of my fund, they might think that companies building valuable and proprietary datasets (and tools for working with those datasets) present the best opportunities. If an investor has a thesis, they will invest exclusively or mostly in companies that fall within that thesis.

What year are the numbers from? I have a hard time believing that New Zealand pays 3x as much for its LEDs as the United States does.

800-lumen LEDs are already down to $15-20 unsubsidized in the United States. Some utilities also provide a subsidy for each LED.

Granted, the 10-watt LED does not save you much in power costs over the 13-watt CFL of equivalent brightness. However, the LED is already cheap enough to be a viable replacement for incandescents in bathrooms, and other areas where high cycling rates will kill CFLs.

Yes it does, and it exists for ventures above a certain size, such as banks. Why not democratize that policy? The free market you mention and defend does not actually exist.

Your argument essentially boils down to "taxation is a violation of individual rights", since a democratic government tasked with feeding its people would obviously fund production of the food, rather than needlessly trample property rights.
> Provide jobs to the unemployed through farming...

It's actually possible to earn more than minimum wage as a farm laborer, yet there is a farm labor shortage and a drive by the UFW to recruit the unemployed met with astonishingly poor results. See http://www.sfgate.com/politics/article/Berry-growers-UFW-beg....

> Take their rights away? No. Destroy their income earning ability? Probably.

That's a great idea. I'm not sure why I didn't think of it. I guess I forgot that no doctors have ever opted not to accept Medicare.

Taking your epiphany a step further, since software is such an important part of life and the economy, maybe we can destroy the income earning ability of software engineers too while we're at it. I'm sure everybody around here would be happy with the arrangement.

> I would provide more rights to nurse practitioners, subsidize their training with job guarantees...I would invest heavily (through DARPA and the NIH) in continuing the development of vaccines and protocols for chronic illnesses (thereby providing STEM jobs), and leveraging DARPA (again), continue to invest in robotics for robotic surgery apparatus (a la DiVinci Surgical System).

Thank goodness the United States government doesn't have a problem with debt. If it did, all of your investments and guarantees might be impossible to make.
I was born '80 and consider myself to be in the nebulous area. My sister is '83 and is firmly 'Y'.

I saw the college bubble popping. It's why I went to night school and graduated debt free from a state in-state urban public university with a solid, practical program and a degree in business. It was a tough few years, but it also set the expectation that life would suck for a few years and then would get better, and I would find a way to do what I wanted after I met the goal.

Too many people, the author of the linked rant (I won't dignify it by calling it an article) seem to have been sold a promise of a fulfilling fun college experience and fulfilling fun career if only they mortgaged themselves. Mortgaging yourself never is a good idea. That is a horrible approach. I hope that the generation now in high school learns from their errors.

Total employee compensation does (i.e. you have to include taxes, benefits, etc.). It's easy to see why - if someone produces way more than they cost, then employers will be lining up to hire them.

It's like as if you could buy widgets for $.10 and sell them for $1.00. You'd buy as many as possible!

Yeah, that's a surprise. Increasing RAM would surely have been an easy way to speed up video editing. What else are we to do with the fancy camera?!
DRAM requires periodic refreshing or the cells lose their memory. This refreshing uses energy. More bits, more energy. You get the same issue with SRAM (think CPU caches) though without the refreshing.

There's just one problem: the cost of providing your social safety net can't exceed what you can reasonably/realistically collect in taxes.

Tax revenue, when it's growing, grows linearly. Debt, however, grows exponentially. That explains why the total debt burden of the federal government, if you include unfunded liabilities, exceeds $70 trillion even though federal tax receipts last year were above $2.5 trillion.
It also has to do with increased global competition. In the wake of World War II, much of Europe and Asia was destroyed and in turmoil and had a lot of rebuilding to do. By the 1970s and 80s many countries had caught up and started seriously competing with the US in things like automobile manufacturing.

I agree it is far from cut and dry. I have lived in Africa and Asia for 5 years - the rest in USA. Billions of people today do not have electricity and clean running water in their house.

Air conditioning, that many in the USA act like is necessary wasn't available in 1950 in the USA (in any significant way) and in much of the world until fairly recently.

Even things like access to a library and school is far from universal today. The internet is a great boon in providing access (and is available to more than have access to a library).

I don't see any quick and decent way to compare making $40,000 in the USA today with making 1/2 that much somewhere else. But I do know that what you can live on for $40,000 in the USA today provides luxuries most people today, and in all of human history, could never have afforded (electricity, indoor plumbing, heat, air conditioning, TV, car, cell phone, internet, food, clothes...). Yes you don't have as fancy stuff as you can see other people have. But you have a ton of great stuff.

Getting into debt is a huge issue - as it can really get you into financial trouble. And the current options for going to college are not easy. But it isn't like it was super easy before either. Both my parents had to get scholarships. I would have been out of luck probably.

We often are comparing our "shortfall" to this tiny little stretch of time and location that was great and worrying that it isn't fair it isn't quite as great as that.

I agree there are quality of life issues in the USA that are obscured by cash wealth. I also agree that those in the USA often create a much worse financial situation for themselves by taking on debt for useless junk and then complaining they can't afford to live on so little... (this even happens to rich people in the USA making over $100,000 a year).
Isn't that rather much a false dichotomy? A person with a journalism degree should be able to figure out several ways in which to provide themselves beyond the immediate-but-inadequate burger-flipping versus delayed-and-maybe-still-inadequate that unpaid internships provide.
Yes, DRAM requires power to refresh its memory. That's why computers can't use DRAM as permanent storage.
The CFL works by exciting the mercury vapor in the tube to give off UV, which then strikes the phosphor coating, emitting light in the visible spectrum. This UV radiation wears the coating over time.

I'm not aware of the design of these LED bulbs you mention, but they might work under the same principles, the LED just replaces the mercury as the UV source.

Ancient religious rules required farmers to not take everything from their fields, instead leaving whatever was missed/fallen for the poor to gather for themselves. Notice that it involved the able-bodied poor making the effort to take advantage of benign neglect, and not idly waiting for the farmer to dole out a significant fraction of what he reaped. Contrast this with the modern "basic income guarantee" movement, which requires nothing of the able-bodied "poor" yet requires productive workers hand over a good chunk of their earnings; this new notion is hardly pragmatic and reasonable save to those who would benefit from it (aye, many would be quite satisfied living thereon).
