Comment Re:So you want a tax on wind and solar. (Score 4, Interesting) 390

You're missing the point of a carbon tax. The tax is meant to speed the end of fossil fuel use. And really it's natural gas that killed coal, so you're going after the wrong target.

The current market forces point to a direction of renewables, natural gas, and whatever nuclear remains operational (with no new nuclear plants). That's not a bad plan for the US for right now. However, natural gas in the US is currently 1/3 to 1/4 the cost of any other natural gas in the world. It is exceptionally, and historically cheap. Various people estimate that this low-pricing situation will last between 15 and 100 years. My personal opinion is that it is difficult to make estimates on that kind of timeframe.

Regardless, if natural gas in the US ever approaches the cost of natural gas elsewhere in the world, US consumers would be in for a very rude awakening on their utility bills. My personal opinion is that we should not eliminate these plants entirely. It isn't wrong to let market forces dictate our choices, but we should hedge against unfavorable market changes in the future.

Disclaimer- I'm "in the industry", my customers are roughly 60% gas and 40% coal.

How is that ratio modified by the electrical costs of running an 8 core FX chip? They consume like twice the power that zen does for like half the performance.

The Ryzen 1700 is a 65W chip, the FX-8300 is a 95W chip. Assuming you are running the machine at 100% load 24/7, and these ratings are accurate, the FX-8300 will cost you $1.75 extra per month at $0.08/kW-hr. If you want to consider the added AC load, you can round up to $2.50 per month. Given the price difference between the chips (currently ~$310+ vs ~$120), it would take more than 6 years to get to the electricity cost breakeven point.

Turkey is a bit like North Korea. The dedication to the country is absolute and the country can do no wrong, not in history, not in the future. Turkey wants to be a member of the EU. Yay Turkey. Turkey thinks the EU is an evil institution against everything Turkey stands for. Yay Turkey. Turkey doesn't have a dark and evil past, anyone saying otherwise is just trying to re-write history. Turkey's current supreme leader is nothing like a dictator. Anyone saying otherwise is just a supporter of Fethullah Gulen who had the audacity to try and overthrow the Turkish government by coupe ... while not even in the country.

All over Europe, the only foreign flags I see waved at protests are for Turkey, the greatest country in the world. We don't want to live there, but don't you dare tell us they aren't the greatest. Yay Turkey.

Also genocide didn't happen.

Everyone else's propaganda is easy to dismiss except your own. Our reality is defined by our experiences, and we have different experiences. Therefore one person's "Absolute Truth" can easily be another person's "Propaganda not based on reality". The USA (and your country, if it is not the USA) blows a lot of smoke, stretches the truth, and perpetuates outright lies for political reasons too.

The demo is interesting, but the results look bad to me. Cropped for sure, but also looks blurry and lots of parallax. I'd rather watch the original, but it is interesting.

Youtube has had image stabilization for some time, and I always prefer the original video. The added blurriness is too much to justify it. You could argue that removing the shakes alters the artistic character of the film as well (for better or worse). In the article's example (following a skier), removing the shakes makes the video feel like it was shot from a drone. The original video is more realistic representation of a first-person view.

Comment Re:NES Classic 2 (Score 1) 104

I'm guessing Nintendo stopped manufacturing the NES Classic BECAUSE it was such a huge hit. They were probably expecting modest sales far lower than what they were, so they outsourced as much as they could, half-assing the device. Thus why it's not (officially) expandable, has no internet connectivity etc.

The NES classic sold around 1.5 million units. The Wii U sold 13.56 million over its lifetime. Arguably the Wii U had a much longer lifetime, and you could actually buy one for a larger % of that lifetime. But I wouldn't say the NES classic was a huge success, for Nintendo. It had no continuing revenue stream after sale, was found to be easily hacked to play other NES, SNES, and even N64 games. From an accountant's perspective, that's a negative revenue stream since it may erode Virtual Console sales. Accountants run the show nowadays, so it is not surprising they killed it.

Comment Re:So you exclude half the taxes and what you get? (Score 1) 903

By the time you take all that stuff into account the US is likely to be *way* further down the list. Property tax isn't high in the US (typically around 1.5% of the value of the property, which is similar to, or lower than council tax rates in the UK). Sales tax is typically extremely low (typically less than 6%), compared to the UK's 20% VAT. Taxes on fuel are typically extremely low 18.4/gal, compared to the UK's £2.19/gal (273/gal).

Property tax in the US can be misleading. The average in Texas is supposedly 1.9%, but many communities have municipal utility districts added on for things like hospitals, fire stations, water supply, sewer, flood mitigation, schools, etc. The effective rate in the neighborhood I live in is between 2.5 and 3% of the assessed value, which is close enough to market value for discussion purposes.

Comment Re:Wait wot? What about the Nexus 4? (Score 1) 92

Because despite the terrible summary, the claim isn't about Apple hindering the performance of its chips. It's about Apple claiming there's no discernible difference between Intel & Qualcomm iPhones. The section about hindering performance is a couple of paragraphs of background in a multi-hundred page document, but for some reason the press has latched onto it.

The relative performance of Qualcomm vs Intel chips may be interesting to you and me. And the lawyers are more interested in that, since Apple may be making false claims which harm Qualcomm. However, It's more interesting to the average person that Apple may be deliberately slowing their phone down.

Comment Re:3d Printing Profitable (Score 3, Interesting) 73

Titanium scraps can be recycled, although there is a cost in doing so. I think an additional reason is 3D printing may allow parts to be created with less titanium. They can have hollow areas or achieve shapes that milling can't.

My concern would be in part strength. AFAIK, 3D printed metal is typically weaker than forged and milled metal. Maybe things have progressed or these particular parts don't need "full titanium" strength.

Titanium is also a pain in the butt to machine. We figure 2-3x more machining cost compared to the same part made of 403/420/422 stainless.

This part of the article is particularly informative-
General Electric Co is already printing metal fuel nozzles for aircraft engines. But Norsk and Boeing said the titanium parts are the first printed structural components designed to bear the stress of an airframe in flight.

Gas turbine fuel nozzles are a very complicated shape and have relatively thin walls. In other words, a nightmare to machine conventionally. They have to withstand very high temperatures, but mechanical stress is low. Additive manufacturing makes a lot of sense for these parts.

Load bearing parts, on the other hand, will have higher mechanical stress, and traditionally this is where additive manufacturing is vastly inferior to traditional manufacturing. It may also prove much more difficult to inspect the parts. You can 3d print a beautiful part with a complex hollow or honeycomb shape designed to keep material costs to the absolute minimum, but how do you inspect it? Magnetic particle Nondestructive examination (NDE) is not viable, since titanium isn't magnetic. Ultrasonic NDE inspection doesn't do well with complex shapes due to all the odd reflections generated. Dye Penetrant NDE will only find surface defects. The only other reasonable option is Xray NDE, which is fine for some parts, but very difficult if the geometry is too complex.

With a conventionally manufactured part, you normally inspect the billet or bar before starting machining. With additive manufactured load bearing parts, there is no easy inspection method, either during manufacture or in-service, for complex geometries.

Comment Re:To the college student who wrote this (Score 1) 364

The headline is referring to the total amount of student loan debt, which isn't totally related to the per-person amount of debt at graduation -- for instance, if more people are going to school and taking out loans; or if people are taking longer to repay their loans, the total amount of debt will increase even without the initial per-person amount increasing.

Of course, the way that the headline and summary were written were obviously going to cause confusion. Too bad that apparently stories are posted by retarded baboons here on Slashdot.

I'm only one datapoint, but my loan servicer for my government loans (I did not take private loans) reduced the interest rate by some % for every year that I paid on time. Near the end, I was paying 2% and even 0% interest on some of my loan groups. I was in no rush to pay them back early since every other loan I had was at a higher rate.

Comment Re:Remake of old movie (Score 1) 106

This is a remake of a 1999 movie. Plot summary: AMD had a chronically weak offering, Intel was in the habit of dribbling out the performance gains. AMD suddenly came on very strong with Athlon, a completely new chip which was arguably faster than Intel and definitely cheaper. Almost overnight, Intel suddenly figured out how to make much faster chips, and so did AMD. Performance doubled, tripled, with AMD being the first to crack the 1GHz barrier the next year. That spiral continued for a few years and the users were happy, but AMD ultimately fell behind and Intel went back to their old tick-tock.

Obtaining higher and higher chip performance seems analogous to natural resource extraction. If it is harder and harder to keep getting the same gains, let those gains sit in the ground until they are actually needed.

One really sneaky way they do this is by giving a large price range on their website for different apartment floor plans. You have to choose a floorplan type, then a floorplan subtype. Depending on what options you choose, they can narrow down exactly how much an individual is willing to pay.

Comment Re:All I can say is good luck (Score 1) 100

As a nerd who is insistent on trying out the myriad of this-and-that technologies, I had a Windows phone a couple years ago. It was a fairly high end HTC device. While the interface is unique, the more I began to use it, the more it became obfuscated. It reached a point where it went from fairly cool and useable to finding myself lost on my own phone. Here I speak of the tiles and such. One thing I have noticed over the years, is that the elderly, who expect and do much less with and from their phones than myself, seem to have become the dominate user base. And yes, I do peek over shoulders just to see what platform different demographics are using. For me, Windows phone lasted a good couple months before going back to Android. I do not regret the experiment. But whatever they are planning with this surface phone, it had better be.... different in a good way. I will say this: I have a Windows 10 tablet. It is running a quad-core Cherry Trail with 4 gigs of ram. Quite simply, it is the best tablet experience I have ever had. It has a "tablet mode", but just using regular old Windows 10 on a tablet is pretty nice. Disclaimer: I own several tablets and they all have their uses (security cameras, persistent weather info, etc...) but my next favorite tablet is my Amazon Fire. It is simply the best for content consumption. It plays in my shop all day. I do not expect this post to be popular.

I completely agree, I have a Windows 8 tablet with a 10" screen, a low-power atom processor and 2gb of ram. I run it in Classic shell mode 99% of the time. It was less than $400 new, and is lacking performance, but is still the best tablet experience I have ever had. It's too bad that Microsoft hasn't figured out how to make a decent platform for a screen. Backwards compatibility with the x86 ecosystem is the best Microsoft feature and their phone OS doesn't have it. If they had a classic shell mode with x86 compatibility (by emulation or otherwise) on a Windows phone, I would probably buy it. It looks from some old news stories last fall that the new Windows Phone OS might get x86 emulation. Maybe they can pull it off. But they will probably fall on their face again somehow.

Comment Re:Law mandated technology (Score 1) 269

I love how political types think that we just need to mandate using less power, oh and this time at ever increasing rates because that worked for a few decades for transistors.

Ironically, computers are one of the least regulated industries on the planet.

If you want to see what mandated goals do, check out your health insurance bill, the government has been regulating that industry for 40 years.

The government doesn't have that much to do with US health insurance costs, in my opinion.

Today, March 25, 2017, the population of the USA has access to the most advanced medical care in history. And tomorrow it will be even more advanced. The advancements in medical science in the past 10 years, let alone 50, are absolutely staggering. The government meddling in the healthcare market is only part of the picture. There is simply a lot more procedures, medicines, and devices on the market than there were last year. And the same will be true next year. The USA has figured out how to advance medical technology reasonably well. Now we have to figure out how to provide value for the dollars spent. That isn't an easy thing in an industry that is primarily for profit.

Even in a 100% cash-based, market type solution with no insurance whatsoever, you'll still have the problem of the dentist/doctor/surgeon who recommends fixing 15 problems when a value-based approach would recommend that 3 be addressed. I know this to be true because I have been with and without dental insurance during my career and it made no difference in the value basis of the recommendations that I received.
