  1. Re:Same reason blu-ray didn't take off on Dell Demos 5K Display · · Score: 1

    "The real question is, where are you going to get 4k sources from..."

    I'd like it for my home video. I've been taking 1080p @ 60 fps for 3 years and it's definitely worth the extra required space. The extra framerate makes it much more realistic. I noticed when shopping for a new video camera there are quite a few that shoot 4K.

    "Up-Converting" is just a marketing term for scaling and scaling is a techy phrase for stretching. Of course 4K should look better. You can't magically add (real) information that isn't there to begin with.

  3. Re:flywheel on Power Grids: The Huge Battery Market You Never Knew Existed · · Score: 1

    While the cost of pumped storage is not going to change, battery costs can and likely will come down. One example http://www.technologyreview.co... would cost about $30,000 per MWh, 1/6 or less of current tech. That's $30 million per GWh, almost 10 times cheaper than pumped storage.

    I know battery breakthrough stories are a dime a dozen, but progress in this area is quite likely since you don't have the power density constraint of small devices. The primary driver is material cost, not power density. The amount of energy stored is arbitrary as these batteries consist of components which can be individually adjusted (e.g. use larger tanks for liquids).

  4. Lean Muscle Mass on Low-Carb Diet Trumps Low-Fat Diet In Major New Study · · Score: 1

    The low(er) carbohydrate group had more muscle, which translates into a higher metabolism. They also, by nature of the diet, avoided highly processed foods.

    """
    The high-fat group followed something of a modified Atkins diet. They were told to eat mostly protein and fat, and to choose foods with primarily unsaturated fats, like fish, olive oil and nuts. But they were allowed to eat foods higher in saturated fat as well, including cheese and red meat.

    The low-fat group included more grains, cereals and starches in their diet. They reduced their total fat intake to less than 30 percent of their daily calories, which is in line with the federal governmentÃ(TM)s dietary guidelines.
    """

    The low carbohydrate group ate more protein, which is essential to maintaining muscle. Also, knocking out "cereals and starches" probably knocked out highly processed grains and sugars. I think it's not so much what they're eating but what they're NOT eating: highly processed CRAP.

    Lookup Clarence Bass. The guy looks GREAT at 75 and has maintained (and written about) a moderate diet and exercise plan since 40. I'm nearly 40. I love being active. I've competed in many sports including soccer, football, track and bodybuilding. I still have a good metabolism, good muscle mass and low body fat. Through variations of my diet I've found that a moderate diet including unprocessed or minimally-processed and uncooked foods is the best diet for me. Whole milk, nuts, avocados, fruits, brown rice, beans, salmon, lean beef or turkey, steamed broccoli, etc. A low carbohydrate diet makes me weak. I can't muster the explosive energy for an intense exercise session while carbohydrate depleted. When in ketosis (completely carb depleted), my breath smells like alcohol, my joints ache, I'm irritable and generally feel like crap. Maybe I'm different. My favorite pre-workout meal is a bowl of rice about an hour before. Carbs are fine. Just not the super-processed stuff.

    According to Honda's website, the Clarity has a range of 240 miles, less than Tesla's EPA range of 265. Definitely not costs seeing as how the hydrogen costs more than gasoline. But you do have fueling time, assuming you can find a hydrogen fueling station.

  10. Safe Routes on FAA Bans Delivering Packages With Drones · · Score: 1

    As a compromise, the regulators should approve routes that avoid populated areas. This would minimize risks in the event of a crash. Also they may need some sort of traffic monitoring and control infrastructure to handle multiple companies performing deliveries.

  12. Re:Why would I buy a Prius on Are US Hybrid Sales Peaking Already? · · Score: 1

    Most car enthusiasts get a manual in a sports car for control, not "engagement". Triptronic is just the old style automatic with options to "slowly" select gears. This is not the same as Porche's PDK and the likes.

    If you've payed attention, all the high end sports cars are going to automatics in the form of "automated manuals" such as Porche's PDK. They're superior to traditional manual transmissions in all ways. Shifts in these advanced transmissions happen in about a tenth of a second. I've driven a Porche Panamera and a Mclaren MP4-C and had no want for a "stick shift" in either one. I think some Lamborghini and Ferraris don't even offer stick shifts any more.

    As for noise, that's just baseball cards in the spokes. If see Mustangs and Pickups making lots of noise while hardly accelerating. And as a tech, you should know that sound is wasted energy. I'm over it. Give me instant torque all the time and great handling. That's the real fun.

    Set a parity ratio depending on risk vs. space loss tolerance. Say it is 1000. You can lose any of 1000 bytes in a parity group and recover while only giving up .1% of your disk space to parity.

  14. Re:Neither of the above, it will be CNG on Future of Cars: Hydrogen Fuel Cells, Or Electric? · · Score: 1

    The only production CNG vehicle in the U.S. is the Honda Civic GX, which has a range of 250 miles, 200 miles less than its gasoline counterparts. It also has a $10,000 premium price tag at $29,000. And as for fueling at home, Honda recommends against it to fuel quality concerns and will void your warranty if you do. That means we need an entirely new fuel infrastructure.

    So we roll out CNG fueling stations. Maybe doable in 10-15 years. Then what happens when we run out of NG? We have 11 years (http://en.wikipedia.org/wiki/Shale_gas_in_the_United_States) of proven reserves and 100 years of "postulated" reserves. I'll bet those numbers drop quickly when we switch out gasoline for CNG. On the other hand, electrified vehicles are immune to fuel changes so our investment in infrastructure has 0 risk.

    A large part of that energy you are counting comes from oxygen in the air, not the gasoline. A fair comparison would be to lithium-air, which has 5-10x the energy density of standard Li-Ion.

  17. Re:Nuclear? on UN: Renewables, Nuclear Must Triple To Save Climate · · Score: 1

    "When are you environmentalist nuts start studying how the electrical grid actually works instead of having fantasies about how it should work."

    While a agree with your sentiment about anit-nuke positions, I think your "study the grid" viewpoint is narrow-minded.

    Power demand (and thus supply) fluctuates greatly throughout the day. I'm an M.E. I worked for FPL, who know runs three solar power plants. I know how the grid works and it's sad that we still have to match production to demand. Energy storage systems are long overdue. There are some in place including uphill reservoirs, flywheels and thermal salt storage, but we haven't arrived yet. Though I'm not sure if centralized or decentralized (panels on houses) is best, it's clear that grid storage is a necessary step that will enable much needed flexibility on our power grid.

    Grid storage is no more a "fantasy" than splitting atoms. I personally like nuclear. And I like wind and solar. And geothermal. They could work together nicely as base plus spike production. After we move to grid storage and look back, our current system of ramp production to meet demand will seem ridiculous and truly ancient.

  18. Re:Hardware requirements on Meet the Diehards Who Refuse To Move On From Windows XP · · Score: 1

    XP has been used as an embedded system on some large format scanners, printers, lab machines and other specialized hardware where I work. Other machines such as digital copiers have their own OS providing services such as SMB, FTP and other network services. Do you think these other OS's are somehow inherently secure and free of security holes? Why require embedded XP to have current updates and not the other embedded OS systems?
