    We're power pigs at this house due to all the DVRs, computers, etc, something like 33kWh per day based on the month's total consumption.

    With some extensive re-wiring of the power panel to move high-load devices (AC, washer/dryer, dishwasher, possibly even the gas furnace blower motor) to another panel, the 10kW unit MIGHT be useful to keep the fridge and lights going during a short-term power outage. Sadly I think the computers would have to get shut off to even get 12 hours out of it.

    With the rewiring necessary, I'm not sure it's even cost competitive with a natural gas generator. 16kW units with automatic transfer switches are around $3600 and will run the entire house, including high power stuff, indefinitely.

    Where I live, it's all kind of moot. I can count on one hand the number of outages we've had in the last 16 years on one hand and only one was long enough to even justify a trip to the dry ice store to keep the fridge from melting.

    If it was even remotely more common (1-2 times per year, 24 hours) one of the Honda suitcase generators would probably be more effective just to keep the fridge going or maybe the gas furnace blower. Beyond that level of frequency or duration I think a natural gas generator would be useful.

    First, none of these things move forward without some enthusiast buy-in. Loads of things are stupid from a strict dollar-efficiency perspective but people still do them anyway. Computers held fairly low value in terms of dollar efficiency for decades, but enthusiasts found them worthwhile and helped move that industry forward.

    Second, you confuse cost and value. You know the cost of the utility power and the off-grid generation and storage components but you don't know the value to the consumer of being off-grid. What you see as a splurge they may see as some kind of inherent value.

    My assumption is that a level 1 employee who excels at their job gets promoted to level 2, repeating that cycle until they get to the level where they no longer excel at their job and receive no more promotions.

    I think it's debatable whether an employee at their plateau level of promotion is merely good enough or actually incompetent. It's probably both and circumstantial. Someone promoted to their plateau may be just good enough not to get terminated immediately but not good enough to retain the position long term when faced with a superior replacement.

    And its probably this kind of self-aware incompetence which traps managers into hiring underachievers. Their personal success requires their underlings to be good enough but not good enough to challenge them, which I imagine is only magnified down the line.

    How is the dollar or any currency used as a peg currency?

    I don't see why a country couldn't just say "Our currency, the fubar is pegged at the rate of 10 fubars to the bitcoin." Anyone needing to conduct transactions in fubars would have to then buy 10 fubars for one bitcoin.

    The only way this works, though, is for the government to restrict transactions in other currencies and only allow the national bank under their control buy foreign currencies. I think some get even more draconian, forcing travelers to trade all their foreign currency at entry to the local currency at the official exchange rate and then sell you your own currency back at exit.

    Of course this doesn't stop black markets for currency, every country with an official exchange rate has them, more so if the official exchange rate is greatly detached from reality. But these can be dangerous and you may find you detached from your freedom.

  8. It's the missing competition on Rand Paul Moves To Block New "Net Neutrality" Rules · · Score: 2

    While I support net neutrality as a concept and as a form of regulation (with a big dash of hope, too), none of this would be an issue if there was any competition for residential high speed internet access.

Providers who did this would be gutted by the market for vendors who didn't do these things. This is all rent-seeking behavior by monopolists, and worse, by monopolists whose business model can see its own funeral on the calendar.

    Making synthetic fuel when you have energy to spare could be a pretty smart storage mechanism.

    Wonder what the efficiency is like though.

    Since you're using "spare" energy which you can generate "for free" does the specific efficiency even matter? The efficiency of not using the energy is zero.

    The only efficiency that seems to matter is the money cost of the equipment relative to the value of the produced synthetic fuel.

    If you have 10 wind turbines and on a windy day you can only use the power from 5 of them, you would probably brake the other 5. The only cost to turning them for synthetic fuel usage is the wear associated with having them turn. I don't know how significant this is -- maybe they aren't designed for a 25 year lifespan of continuous rotation, maybe all those wind surveys and grid analysis they do get plugged into the engineering so that they can say the finished product has a 25 year lifespan because they know they will be idle/braked for 15 of those years.

    Thus the free power is a lot less free because it will wear your turbines out much faster because you're spinning them more than for grid power.

    AFAIK, artificial sweeteners trick the tongue into tasting sweet but don't contain the chemistry (namely sugar) to induce an insulin response.

    Now, that doesn't mean it couldn't happen (insert complex biochemistry here) and I wonder if there is possibly some kind of adaptive learned response associated with the taste of something sweet triggering it, sort of like a Pavlovian response. Or maybe there is some indirect connection with our taste buds and our insulin response -- it's not hard to see where taste and an instantaneous biological response would be beneficial, either in helping us reject poisons or in making some foods more quickly absorbed.

    It also makes me wonder if could be un-learned -- if a person never ate anything sweet tasting that had sugars, would the body stop associating the taste of something sweet with an insulin response if there wasn't a corresponding increase in blood sugar?

  17. "Need" definable for social integration? on Robots Step Into the Backbreaking Agricultural Work That Immigrants Won't Do · · Score: 5, Insightful

    It's easy to talk about material goods as being "unnecessary" especially if they do not contribute to one's physical safety or health, like shelter, food and water.

    For better or for worse, though, we are a consumer society and some things almost start to seem to become needs not because they contribute to our physical safety or health but because they contribute to our ability to integrate socially.

    You may not "need" the latest smartphone but at the same time, especially among younger people, you could almost say you need to have a smartphone capable of accessing social networks in a reasonable manner because it's extremely difficult to integrate with many peer groups without one. You will not be able to participate in group dynamics or posses the same social information as other people.

    The same thing could be said (more tentatively, because there are other outlets) about Netflix. If you're not able to engage with people socially because you are unaware of the types of programs they consume and cannot participate in discussions about them you are also hindered in group dynamics.

    Outside the electronics/media sphere, you can make similar judgements about clothes. You don't "need" clothes that fit a specific fashion or brand paradigm -- you can buy used clothes or dollar store clothes and meet the minimal functional needs for clothing. But style and manner of dress is very important for engaging in peer groups, and like it or not people are in/excluded or find it easier or harder to engage in social activities if their mode of dress is compatible with their peer groups.

    Now it's easy to make a lot of value judgements -- especially about social networking (the companies, phenomenon, etc) -- but their existence, usage and impact on social life is a reality and at some point I think some of these things become needs for reasonable social integration. Excluding them because they don't meet some minimalist description of "need" starts to sound myopic and mean spirited because I don't know anyone who just lives based on minimal need.

    The summary seems to indicate that the value of "Stellarwind" wasn't clear because it was one of many sources and few had access to it, not that all NSA spying was seen as ineffective.

    The NSA does so much spying that it seems like it would be hard to ever calculate the marginal value of each additional unit of spying. Probably more so because of the fragmentary and unreliable nature of clandestine information and the need to develop multiple sources to achieve any kind of confidence about a particular conclusion or piece of information.

    The latter bit is probably what leads to never-ending development of new data sources and methods, especially as each new spying method becomes less and less specific and requires more and more analysis to tease out information. Call metadata doesn't tell you what was discussed or necessarily who was called. You need parallel data from some other source to tell you who is associated with those numbers, where they were, etc.

  20. One 6 Plus glitch on Ask Slashdot: What Are the Most Stable Smartphones These Days? · · Score: 1

    I've had one problem with my 6 Plus which was annoying enough to care about, crashing Safari when rotating the phone from portrait to landscape once a certain amount of tabs were open. Googling the problem I found a couple of threads on Apple's support web site, so it appears not to have been just my experience.

    The fix with the initial release was to close all tabs (an annoying task in Safari), as there is no "close all tabs" function. I don't know that it's been a problem in 8.3 so far, and it seemed to be better in 8.2.

    I didn't experience the issue with Chrome or with other apps, just Safari. I suspected something wonky with the nitro js engine improvements and the 6 Plus display size as occasionally not long before crashing would occur, js-heavy apps rotated web pages would not respond to screen taps or would respond in the wrong place as if the running js code didn't have valid screen dimensions for portrait.

    I theorized that closing tabs also nuked cached nitro-compiled js code so that subsequent page views didn't have issues.

    Other than that, my 6 Plus has just worked. Historically, I've had to reboot my iPhones to fix a random issue with phone calls more than any other problem and that's been very rare and probably less often than power cycling it for other reasons, like airport security.

    I don't disagree that blocking was the right choice. What I question was whether Comcast's current monopoly practices in the face of pressure across all business sectors (some more than others) are enough to make this merger make sense as a strategic business decision.

    2-3 years ago where I live, you had a "choice" of high speed Internet -- DSL from CenturyLink, permanently stuck in the sub-2 Mbit/sec range or Comcast at 10+. A local Internet provider has been wiring part of the city for fiber -- it's a pretty small area now, but they just announced an expansion and are even offer 10 gig. CenturyLink has been running fiber in residential neighborhoods over the past month.

    So by the end of the year, it's possible that there will be far better choices than Comcast for high speed Internet. Obviously this isn't enough, only one place, limited availability, etc, but it shows that other providers "get it" and see that Comcast is ripe for the picking.

    I think the pressures on Comcast's cable TV service are even greater from Netflix, Amazon, HBO's new streaming option, selective download services like iTunes, Roku "channels" and so on. You can get most content now without cable.

    I'd be most worried if I was Comcast about the original content. Most of what underpins cable is having content, and it may not be unlikely that in the near future the content people want isn't even available on Comcast or any other cable service at all.

    My sense is that it maybe wasn't good business.

    The sectors represented by Comcast (content, cable, internet) all face a ton of pressure from various competition. Amazon and Netflix are actively creating content and building alliances with production companies. Cable is being decimated by streaming and downloadable content (accelerated by excessive cable pricing and poor customer service). Even Internet is showing signs of competition from municipal broadband and other providers -- CenturyLink, who is just about as awful as Comcast from a customer service perspective, just ran fiber optic cable down the poles behind my residential address. The utility guy I quizzed said it was for residential high speed internet.

    The only way this deal made any sense was as a holding action -- give Comcast a bigger local monopoly slice and hope that they can milk the customer base and Netflix, et al, for enough cash that they can keep the wheel turning. Regulatory pressure, net neutrality, etc may even have limited that strategy, at least on the milk-the-content-providers department.

    Mergers are expensive, from the deal costs to the business integration side and I really question whether at the speed their markets are changing that they can maintain customers and margins long enough to profit from the merger.

    It also makes the business a lot bigger, which makes it slower to adapt and innovate, especially when it represents a sector that has traditionally relied on monopoly power and not innovation. Being a bigger dinosaur didn't help the dinosaurs.

    I had a friend who worked at a local hospital system's IT department. About 3/4 of the workforce was native born Americans of various ages and genders and about 1/4 were south Asians. More than a few of the south asians had simply awful personal hygiene -- they smelled like bathing was only an occasional afterthought.

    Numerous employees complained to line management and then HR. Line management ignored it because the employees were OK producers and apparently inexpensive. HR tried to gloss it over until one of the employees brought in some kind of note from a doctor who said that she was extra sensitive to odors. HR finally came up with a list of the worst offenders hygiene wise and told them there had been complaints and that "as a hospital system, we have a vested interest in cleanliness and hygiene and expect employees to respect the standards of cleanliness."

    I think about half "cleaned up" their act and the rest just got moved to some corner of the office.

    I've also seen kind of the reverse, at a college I did some consulting at there was a "clique" of Vietnamese employees there with long tenure but awful skills. They often spoke to each other in Vietnamese and seemed to use their tenure/culture as a way to edge out other employees despite the total lack of skills and abilities. The result was the other employees (mostly white, but one hispanic) ALSO cliqued up and these two groups did not cooperate well at all -- there was often real hostility between the two. When one of the Vietnamese fucked up a wireless config and blackholed half the wireless traffic, one of the non-Vietnamese taunted her verbally about fixing the problem "So are you buying us all lunch if you can't fix this in an hour?"

And even NBCUniversal's strength in content creation is under assault by Netflix and Amazon original productions.

    Even if you assume greater profits from increased monopoly abuse by a combined Comcast/TWC, huge mergers face big costs internally and I'd question whether they will have time enough even as a monopoly to recoup those costs and the investment expenses of the merger deal itself.

    Plus, the larger the entity, the less it is able to adapt to the huge changes sweeping the video content and Internet markets. Cable is already a dinosaur, being a bigger dinosaur has never proven helpful.
