  1. Win the battle, lose the war? on Fuel Efficiency and Slow Driving? · · Score: 1

    Except for a slight (~5mph) lead-foot on the freeway, I generally drive conservatively. But I decided to do some calculations based on driving from our office to our colo.

    I have a compact and can expect around 31-32 at 75. Using the most optimistic measures I could find, I could up that to 42 by slowing to 55. So on that trip I would save about 0.6 gallons at the cost of 23 minutes of time.

    If gas were up to $5/gallon, my break-even value of time would be aout $7.85/hour or about 15-cents below current California minimum wage - pretty bad ROI for someone working in high-tech.

    This, of course, ignores the potential for accident, increased wear on the car, possibility of a ticket (though I have driven for decades without a citation), environmental concerns, etc. And it assumes one is driving alone - additional passengers increase the incentive to speed.

  2. Not a real holiday on Today Is International Talk Like a Pirate Day! · · Score: 5, Funny

    I reminded my wife that today is talk like a pirate day and she said, "It's not a real holiday. If it were a real holiday I would have seen an entire section of pirate Hallmark cards at the store today."

  3. Look at the stats, again on Intel Shows Data Centers Can Get By (Mostly) With Little AC · · Score: 1

    The 0.6 percentage point increase was relative to the average at other data centers. The air-conditioned reference trailer actually did better than their average. But comparing the failure rate in the air-conditioned trailer to the non-air-conditioned failure showed that the servers failed roughly twice as often in the hot trailer.

    It's an interesting start and more work should be done. Even just raising the temperature 10 degrees in an existing facility should reduce AC power consumption tremendously. It would be interesting to see a life-cycle (typically 2-3 year) study in a more temperate climate.

  4. A critical distinction on "Mobile Plate Hunter" Cameras Raise Questions · · Score: 2, Insightful

    To me there is a critical distinction between two scenarios.

    In the first instance, the device has an on-board list of suspect plates (stolen, warrants, etc.) and alerts the officer when one is detected. Officers have lists of local stolen cars and routinely run plates of vehicles "of interest" anyway. In this use, the device would not be used to store any observed plates - it only alerts an officer of the presence of a plate already associated with a violation of the law.

    In one respect, this reduces bias. An officer can't run every plate he/she sees so there is always some conscious or sub-conscious profiling going on. My guess is that plates of cars driven by young black males are run far more often than those of middle-aged white females with a kid in the back seat. An automatic plate scanner doesn't care.

    And personally, I don't have a lot of sympathy for people who are "merely" uninsured or belching smog. I want those drivers off the road. Now.

    There was a recent crash on the corner by my house - flipped a small SUV over onto the sidewalk where I often walk with my daughter. In that case, the driver had expired registration due to lack of insurance, had actually been pulled over 5-minutes prior to the accident, but was unfortunately let off with a warning and, now running late to work, blew a stop sign causing the accident.

    In the second instance, the devices are installed on vehicles or near roadways and store all plates and a timestamp of when they passed. This type of tracking should be outlawed and if employeed despite being illegal, should not be admissable as evidence in any civil or criminal proceding.

  5. I've wanted this for a long time on Call Someone – Without Having To Talk To Them · · Score: 1

    Pretty much ever since we had answering machines I've thought it would be great to be able to leave a message without ringing the phone.

    A typical situation is that I listen to a message and want to respond but it's not an appropriate time. Instead of remembering to call the next morning, I'd much rather be able to call right then and leave a response that the person can retrieve when convenient.

  6. Taxes/fees? Hell! What about minutes? on Real-World 3G Monthly Cost With Taxes and Fees? · · Score: 3, Interesting

    You got all the way to asking about taxes and fees?!? I haven't been able to get a straight answer to (ever changing) minutes.

    What is the minimum billed increment? 6 seconds like some of our business lines? 18/6 like others we have? 60-seconds?

    When does billed time start? When the call connects? when you press send? When the phone starts ringing? And when does it end? Several companies made a subtle change and switched from connect-start to airtime-start (though still only charging if you connect) thus grabbing lots of extra minutes (but avoiding raising published rates).

    What calls are free and what cost extra? 611? 911? 511? 311? 411?

    When someone leaves a voicemail, does that count as usage? What about fetching voicemail? From a landline?

    Calls on hold with call-waiting? Both legs of 3-way?

    Many years ago a TV show grabbed a rocket-scientist and a brain-surgeon, gave each a phone bill and asked them to explain all the charges. Neither came close.

    It's high time the government set standard definitions (i.e. minutes start when the call connects and end when either party terminates the call. Billing increments shall be 0.1 minutes. Or whatever.) Let the companies set their own rates but conform to standard definitions and bill formats.

    Of course some recent attempts to make phone bills understandable were shot down because then the terrorists win or some such crap.

    Well, its guts, at least.

    I was visiting a friend a short while back and he was doing some development on it. It was sans-case - just some cardboard to hold up the screen above a bare motherboard sitting on the desk.

    Couldn't determine a whole lot but it was running Ubuntu, had solid-state drives and used the Atom chips.

    I was getting ready to buy an eee (finally time to upgrade from my Poqet) but his advice was to absolutely wait till the Dell is out since I would probably change my mind.

  11. Edubuntu? on GPL Edutainment Software · · Score: 3, Interesting

    I'd find a machine and see what you think of Edubuntu ("Linux for Young Human Beings").

    http://www.edubuntu.org/UsingEdubuntu

    My daughter is 3-1/2 and loves the stuff on Linux. She was typing her name on TuxPaint before she turned three but we had to click on the icons for her to set it to text or other modes since the mouse was too big and unwieldy.

    So I bought her a laptop mouse which is perfect for her small hand. Big mistake. She will now sneak into the computer and start up "Paint Penguins" (TuxPaint), draw something, print it and come show us.

    If she's bored with that she plays "Running Penguins" (SuperTux) or "Bubble Penguins" (Frozen Bubbles) or steals my Blackberry to show where Nana lives on Google Maps.

    If she finds my bank-account numbers I'm in trouble. But seriously, Linux has plenty of edutainment software available and Edubuntu packages it in one place. It it also designed for classroom (and therefore, I suppose, library) use with features like centralized-management (LTSP) and such.

  12. Do it like the colos do on What Kind of Alternate Business Models Could ISPs Use? · · Score: 1

    Once you have ponied up for the gear, it pretty much costs the same whether you use it to push one bit or billions. That is how the colos typically charge - by the size of the pipe.

    Put 5mb/s for a few minutes and you will pay the same as running 5mb/s 24x7.

    I would like to see the consumer ISPs be required to adhere to uniform standards for service description - sort of like cars and mileage. My preference is that if they specify performance levels they must specify:
    Bandwidth: 99.9% of the time the data transfer rate will exceed X bits-per-second
    Latency: 99.9% of the time the round-trip delay to the ISPs upstream provider will be lower than X ms.

    And since network neutrality should be the law, traffic-blocking games a-la Comcast should not be an issue.

    Of course the regulation would have to prohibit making up your own measures and hiding the required ones in the fine print. The standard measures would be the only allowed measures.

  15. Could go either way on Encryption Passphrase Protected by the 5th Amendment · · Score: 1

    Ultimately courts could decide that the the key constitutes being a "witness against himself" and entitled to protection.

    Or it could decide it is the equivalent of a lock. I know that the police can force a door for a search warrant - and they are trying to force the key to this drive. But according to the article, a defendant can be compelled to reveal a combination to a safe - basically the same thing: an item in memory that allows access to evidence.

    Stickier is the issue of additional evidence.

    Search warrants must specify what is being searched for. But if I reasonably run across something else, that's fair game. Say that the warrant is for a 60" flat-screen TV. I could reasonably look in the garage, under beds, and such. But I couldn't look in a shoebox, desk drawer or other area too small for the TV. So nearly all search-warrants also specify "indicia of residency". Phone bills, rent/mortgage payments, electric bills and such help prove the residence was used by the suspect. But more insidiously, such documents could be almost anywhere greatly expanding the "reasonable" search to drawers, files, shoeboxes - anywhere someone might keep documents. "I was looking in a shoebox and found a stolen gun and meth." Score! If someone were compelled to reveal their encryption key it's likely that anything revealed by the key would be fair game.

  16. Lots o' problems on FCC Requires Backup Power For 210K Cell Towers · · Score: 1

    Having gone through pager/cellular outages in the almost-all-California almost-all-day power outage a few years back as well as through rolling blackouts I applaud this effort. It's even more important as more and more people go wireless only. But it's gonna hoit...

    There are already plenty of hand-wringers who try to block any cell site due to "harmful radiation". Now that same group is going to be heading to city hall to complain about noisy/polluting/etc. generators and stacks of batteries full of lead and sulphuric acid.

    And to some extent they will have a point. Emergency generators need regular testing - some critical units have weekly test requirements. It might fly in the office complex or industrial area but there are plenty of cell towers hidden in church steeples and residential areas. Others are in the middle of the desert. And no matter where they are, they will need to be regularly tested, maintained and fueled. For some sites like those covering desert areas, solar may prove attractive. In other cases it may be cheaper to just rip out the site if it only provides coverage in some desolate spot.

    And where you might get away with a small/medium cabinet for your equipment, now you need to have more space for batteries and easy access for regular replacement or, alternately, a site for a generator, noise enclosure, fuel tank, and access for refuling and maintenance. Rent costs are likely to rise.

    It's all going to be passed on to us users anyway. But I would far prefer to pay a tad more for reliability than for cool wallpaper and rad ringtones. Guess I'm getting old.

  18. Misinformation on The Last DC Power Grid Shut Down in NYC · · Score: 5, Informative

    It keeps being repeated, even in this article which says "it can be transmitted long distances far more economically than direct current", that AC is more efficient. This is not really true. The advantage (and pretty much the only advantage) that AC has over DC is that it is relatively simple to change voltages.

    Over the short-haul, this is good since losses are primarily resistive and losses are related to the amount of current flowing in the conductors. Power in my neighborhood is delivered at 12,000V and down-converted to 120/240 by transformers located every few houses. Delivering power at 120V would require 100 times the current and massively larger conductors. Once it gets to my house, with the exception of some motors and some lights, everything from TV to stereo to computer ends up having to take that power and reconvert it to DC.

    But AC has far higher losses through capacitance and inductance which become severe over long distances. This is why some current and other planned long-haul transmission routes use DC. A good example of this is the 800-kilovolt DC line that connects into the Sylmar Terminal Station near Los Angeles.

    Apparently, the use of Extra High Voltage DC is being proposed for a number of new long-haul transmission systems and it is the high losses incurred by AC over long distances that is driving the use of DC.

  24. We need "lightbulb" computers on Internet Uses 9.4% of Electricity In the US · · Score: 2, Interesting

    Trouble is that leaving computers running is arguably a rational business tradeoff. If a desktop computer draws 250 watts (and most don't average that high), and is left on during all non-business hours (assume one works only an 8-hour day and no weekends) that is 128 hours or 32 kWh or, at $0.10/kWh, $3.20.

    If your entire employee cost (pay, bonus, worker's comp, medical, office-space, etc.) is only $60,000/year, an employee needs to save less than 10-minutes/week to break even.

    One coder measured his own pretty high-end machine (including support for 3 monitors) at less than 140 watts when not doing heavy processing. This doesn't include the monitor which in most systems sleeps after a short period anyway. If we use 150 watts, a 9 hour day, and $100,000 employee cost then break-even happens by the time you have saved 2 minutes 15 seconds per week or less than 30 seconds per day.

    Now if it takes 2 watts cooling per watt of usage then the benefits of shutting down are greater. But on the other hand, none of the office buildings where I've worked have metered power or cooling (except for custom auxiliary units) so from the tenant perspective, leaving the machine running has no impact on power or cooling costs.

    Sure, for many, waiting for a computer to boot is part of the morning routine and provides an excuse to go fill the coffee cup. But if buildings metered power and cooling usage and if computers were made to save-state and swich off and back on like a light - or at least in just 1-2 seconds - people would be much more willing to power down not only at night but at lunch and whenever they aren't using the machine.
