  1. Tankless heater on Ask Slashdot: Shortcuts To a High Tech House · · Score: 1

    I too have a Tankless; in my case Rinnai for 6 years.

    My biggest negative is that my (large) family likes it too much, resulting in long showers and high water bills.

    This happens because the output temperature is thermostatically controlled (it blends in cold water) so my hot water is always 120 degrees, no more, no less. My shower stays exactly where I set it, the entire time. Since it never runs out of hot water, the "but my sister used all the hot water" fights are non-existant.

    Oh, another "odd" benefit is that I can turn its temperature down to 104 when I refill my hot tub, resulting in it being ready for use the moment it is full.

    If mine were to die today, I would put another one in its place. I can not imagine going back to a tank heater with a permanent pilot light and that would not let me take a shower after my kids get out.

    Keep in mind that they need to be installed on an outside wall because the exhaust pipe is expensive and they need a nearby electric outlet.

  2. College on Ask Slashdot: Store Umbilical Cord Blood — and If So, Where? · · Score: 3, Interesting

    Take the money you would have spent on this and putit into a college fund. Odds of seeing a return on your investment are much greater.

  3. Menubar position on Windows 8 and Screen Resolution: WXGA Still Most Popular · · Score: 1

    I find a 16:9 much more useful if I move the menubar onto the left-hand side. This makes the "usable rectangle" somewhat similar to what I had on a 4:3 with the menubar at the bottom.

    Or with any luck, perhaps it will encourage public transportation. I personally do not see much of an issue with "texting while riding a train".

  5. more firewall granularity on Defending Your Cellphone Against Malware · · Score: 1

    I've often wished the android permission model considered "phone home" and "access the Internet" separately. It seems much less risky to me to allow an application to access a predefined small set of sites than to access "everything".

  6. Wi-Fi vs wifi on Super Wi-Fi Isn't Really Wi-Fi · · Score: 2

    Seems like a lawyer either will be explaining the concept of trademark to his client or will be defending the claim that "Wi-Fi" and "wifi" are not "confusingly similar" to a judge.

    The Wi-Fi Alliance's only real next step is to defend their trademark in an attempt to prevent it from becoming genericized.

  7. Former Congressman on White House Petition To Investigate Dodd For Bribery · · Score: 2

    What makes this particularly interesting is that Chris Dodd is a former US Senator. Shortly before he left the senate, he vowed not to lobby congress, a vow that now appears questionable. Within a few months of leaving the senate, he was hired as the head of MPAA (Motion Picture Association of America), causing some controversy in the process.

  8. Re:Doesn't matter on DynDNS Cuts Back Free DNS Options · · Score: 1

    The ancient PC I was using for a firewall had a sticker rating of 720 watts. The Buffalo router that replaced it is rated at 24 watts and also allowed me to turn off my old WiFi access point. Although there is no question that both stickers overstate usage significantly, I have to believe the general notion that the router is significantly more power efficient and willl pay for itself simply in power-savings. DD-WRT is pretty good at adding back the "customizability".

    The glass ceiling will allow people walking through the plaza to enjoy the artifacts below as well.

    The geologic forces in an earthquake would pale compared to the crushing force of the first skirt-wearing female in the approval chain.

  12. Re:Civil and criminal liability on FBI Seizes Servers In Virginia · · Score: 1

    If you were an impacted client, your next course of action is to file a claim against your business interruption insurance and to locate your off-site backup tapes.

    Given the fact that defense attorneys exist, my bet is that the FBI went through the proper channels (getting a warrant) and followed well-established procedures that are geared towards preventing the destruction of evidence and towards maintaining the chain of evidence.

    Attempting to sue the FBI would likely result in a lecture on sovereign immunity. Even if a miracle happened and you were to prevail, the settlement money would really just comes from the taxpayers, which would have the effect of punishing you and me, not the government employees (other than the fact that they too are taxpayers :-).

  13. convergence ? on Win 7's Malware Infection Rate Climbs, XP's Falls · · Score: 1

    Summarizing TFA ....

    Windows 7 32 bit was 3 PCs per 1000, now 4 PCs per 1000.
    Windows XP, was 18 PCs per 1,000, now 14 PCs per 1,000

    This could easily be interpreted as the infection rates converging together as common tools are used to measure both OSs.

    MSRT only "counts" that which it knows about and it only knows about that which has existed long enough and is wide-spread enough to gather the interest of its programmers. Therefore, one would completely expect it to be "better" at cleaning older things than newer things, which would cause the two numbers to converge.

  16. filters and location. on What To Load On a 4-Year-Old's Netbook? · · Score: 1

    I recommend installing a web filter, such as http://www1.k9webprotection.com/ (commercial but free) and using the filtering categories based on the parent's personal beliefs. Also, I recommend that computers be kept in a "public" place where you can see the screen. To accomplish this, our kids' laptops do not work with wireless until they turn 18. The network jacks are in locations where we want them to use the computer. With a netbook, this is may be a bit difficult as it may not have a wired network jack.

  17. Use the phone's GPS? on US May Disable All Car Phones, Says Trans. Secretary · · Score: 2, Interesting

    What about the house next to the highway? Would the occupants lose their signal every time one of these mobile signal jammers came barreling down the road? Seems like it would be more flexible to require the phone to detect motion using the built in GPS and disable certain features based on speed. For example, texting only works at 4 MPH or less (walking), voice conversations at 65 MPH or less, keypad dialing at ????, emergency calls always permitted, etc.

  18. Delay? on UK Police Force Posts All Its Calls On Twitter · · Score: 1

    TFA does not mention it, but I hope the tweets are delayed from real time. After all, one would not want to give a thief advance notice that the police are on the way. Pretty obvious and I'm sure it occurred to the police, but I am a little disappointed (but not surprised) that the reporter did not mention this aspect.

  21. Re:Let's see if I've got this right on 'Leap Seconds' May Be Eliminated From UTC · · Score: 2, Informative

    If you can't answer "When will each of the next 10 leap seconds be?" and "When were the last 10 leap seconds?" then you are pretty much fucked from a programming standpoint of 'handling' it in any sane manner using common time encodings, which use a count of intervals (usually seconds, or milliseconds) since some specific date and time.

    ftp://time.nist.gov/pub/leap-seconds.list is a publicly available file that lists all announced leap seconds (past and future), designed for use in time conversion functions. And yes, it does need to be periodically refreshed, just like the zoneinfo database.

    Life would be much easier if all manufacturers adjusted for leap seconds in their localtime() and gmtime() functions, rather than in the hardware clocks and their time() functions.

  22. Re:Let's see if I've got this right on 'Leap Seconds' May Be Eliminated From UTC · · Score: 1

    The reason for leap seconds occurring at unpredictable times is that the earth slows down and speeds up over time, just like an ice skater does as they extend and retract their arms. Any activity that moves mass closer or further from the polar axis (upon which the earth rotates) will impact its rotational speed.

    Possible causes for this are changing wave heights (due to the moon or passing asteroids), tectonic plate shifts, volcanoes, erosion, vacationing in the mountains, etc.

    Global warming could potentially even be blamed for longer days because melting polar icecaps would cause global sea level rises, increasing the "width" of the earth at the expense of the "height".

    This sort of reminds me of the old adage that "In theory, there is no difference between theory and practice, but in practice, there is".

  23. Re:Recycling is Bullshit on Smart Trash Carts Tell If You Haven't Been Recycling · · Score: 1

    Not true. Glass is generally profitable to recycle, and is in significant demand.

    This depends entirely on how far away the glass plant is. Glass is heavy, has low value per ton and tends to cause lots of equipment damage due to laceration and abrasion.

  24. Re:Recycling is Bullshit on Smart Trash Carts Tell If You Haven't Been Recycling · · Score: 1

    Pretty much anything can be recycled if you can get the purity high enough and the volumes high enough (e.g. fill a semi trailer a week) while keeping the handling costs low enough, including transportation to market. The recycling industry has developed automated sorting equipment that is pretty slick, but unfortunately expensive in an industry that has low-margins .

    The coolest technique I have seen is done by this machine: http://bulkhandlingsystems.com/product/80?60 . It has a precisely sloped surface that "bounces" the materials. Fibers float uphill and containers fall downhill. Watch the video. It is almost as cool as it is in real life.

    Following closely behind in the coolness factor, http://www.magsep.com/taxonomy/term/2 uses cameras to identify materials and air puffs to move the materials into separate streams.

    Sorting recyclables from trash (it is called a Materials Recovery Facility) results in a low purity product that is hard to sell. It also has lower recovery percentages, because no-one wants to recycle the box that touched the animal waste. MRFs offer household and transportation advantages, but little else.

    Source-Separation (e.g. at the Curb or inside the house) results in the highest purity and highest recovery percentages, but has increased transportation costs and puts greater demands on the haulers and homeowners, particularly when separating into a half-dozen categories.

  25. The math behind cash-for-clunkers on 2 In 3 Misunderstand Gas Mileage; Here's Why · · Score: 1

    And finally, we all begin to understand why cash-for-clunkers program focused so much more on how "bad" the old vehicle was, rather than how "good" the new vehicle is. When you look at replacing millions of cars, the greatest consumption decrease comes from getting the worst of the worst off the road forever, even if they are not replaced with 50MPG cars.

    The TFA claims that

    There are now a few moves toward putting consumption on window stickers, right next to mileage.

    The silly thing is that fuel consumption is already on the labels and has been for years. Look for "estimated annual fuel cost".
