  1. Re:Try an ice pond on IBM Deploys Hot-Water Cooled Supercomputer · · Score: 1

    The problem with the ice slush pond is two fold:

    1) they're in contact with the soil which limits the lower temperature due to ground heat. The economics of insulating the bottom of a pond this difficult.

    2) they're not going down to as low a temperature as we can with the saline batteries. Salt solutions freeze at a much lower temperature. For the pond they want to shoot the ice water out over the slopes when this is used as ski areas. For environmental considerations salt water ponds are frowned on in most places since salt is highly corrosive and kills plants and animals. Big issue so it must be handled with care.

    Our closed loop in a box solves these. We actually have boxes in boxes so that each box is at the right temperature for its function.

    These are all ideas that could be used by a lot of industries and for home use too. Little ways that greening not only helps the environment but saves money. I suspect there will be a blooming in the interest in these sorts of things as the cost of energy goes up. Free energy could change that though. :)

    *grin* That's why we have Kita and friends. See:

    Raven Baiting

    In addition to the avian missiles they've captured there is one raven flying around with a big chunk of it's left wing missing - a perfect bite mark care of Kita. It makes a very distinctive silhouette in the sky. That raven now stays up valley of us.

  3. MSucks can suck iEggs.

    My web site stat counter proves that Macintosh PowerBooks running Safari 4.1.1 are the most common machines and browser combination. The evidence is right there in the logs. Virtually no IE usage at all. Just once in a while when I test that a new page renders properly in IE.

    Statistically significant sample sets are raaather important. :)

  4. Might be storing the heat on IBM Deploys Hot-Water Cooled Supercomputer · · Score: 5, Interesting

    "Rather than simply being dumped, SuperMUC's waste heat is designed to be converted into building heat during winter. Presumably it is mostly radiated away in summer"

    They might be storing the heat rather than dumping it in the summer.

    We are building a meat processing facility. Meat processing facilities use a lot of energy for heating water, cooling carcasses, freezing and general storage & air conditioning. To reduce our energy needs we're storing winter in thermal mass so that we can use it during the warm seasons. We're also using the 'waste heat' from our refrigeration compressors to heat water in addition to solar hot water and the backup of propane heating for the water. All of this will save us enormous amounts of money since we won't have to buy as much energy. Good for our carbon foot print and even better for our bottom line as more money will stay in our pockets rather than being dumped into the environment. IBM could do the same.

  5. How odd on Do It Yourself Biology Research, Past and Present · · Score: 1

    What an odd idea that one wouldn't do D-I-Y research. There is a long, long history of research outside of academia and outside of the big labs. I do a lot of research, some of which I've published - on my blog. The Internet has made it easier to publish, and getting peer reviewed, outside of the strangle hold of universities and the journals. This sharing of knowledge is the real boon of the Internet. The games and other entertainment are just sideshows.

  6. How to keep the poor poor. on The U.N.'s Push for Power Over the Internet · · Score: 1

    "new rules to measure Internet traffic along national borders and bill the originator of the traffic, as with international phone calls."

    Wow, what a great idea for continuing to oppress people. This way I won't share my wonderful ideas with people in their countries. I'll just setup a filter so they can't access my content. They lose and will stay back in the dark ages. How about we also build a brick wall around them?

  10. Farms on 64 Drone Bases Located On American Soil · · Score: 1

    "may also serve as imagery analysis depots."

    Cool! Drones would be a wonderful way of doing orthophoto mapping. I have been using orthophotos in our forestry and farm work for planning. The problem is resolution and infrequent flights due to the high expense of manned photo mapping flights. With unarmed computer controlled drones we could have much higher resolution, more frequent orthophotos made which would be very useful. This greatly cut the cost producing these useful photo tools. I want a drone!

  11. Lack of responsibility - Insurance Companies Pay on Ask Slashdot: Why Are Hearing Aids So Expensive? · · Score: 1

    When a buyer has to pay for things they shop around which drives prices down. When anything goes, as with insurance, then the prices go up. This is the same with all medical care, auto repairs are like this to a large degree, etc.

    Solution? Get rid of insurance payments for things like this.

  12. No Classic or Rosetta on Apple News From WWDC and iPhone 5 Rumors · · Score: 1, Interesting

    Apple has abandoned Classic and Rosetta so now there is a tremendous amount of software, and the data accessed by said software, that can't run on the new machines. This means I can't upgrade all our machines as we still need access to our old data. Their hardware is plenty fast enough to perform the emulation. The only excuse for Apple's dropping Classic and Rosetta is greed. But the result is lost sales of Apple.

    Gladwell doesn't get it: Gates is like the robber barons who realized that after all the evil they have done they now need to spend a portion of their fortune, just a small part, on buying back their soul. He is not doing charity work. He is buying publicity and he hopes his soul with it. Think Rockefeller. Think great Evil.

  16. Not real world on How Many Seconds Would It Take To Crack Your Password? · · Score: 1

    Dumb theory. In the real world the cracker has to wait for a response from the system. If the cracker tries too many times, too fast or such then the system just locks the cracker's IP out and if this keeps happening locks the account out for a timeout. This makes it take centuries instead of seconds.

  17. Oppression on UN To Debate Taxing Internet Data · · Score: 1

    What a beautiful way to oppress more people. I already block a lot of countries from my web sites because they are the source of too much spam. If the politicians, add taxes and I'll block their countries too. This will result in lost opportunity to their citizens, depress their knowledge base and crush their economies. Brilliant.

  19. Not strange, better. on Odd Laptop-Tablet Hybrids Show PC Makers' Panic · · Score: 1

    This is how tablets were envisioned before and frankly it is better. The iPad allows a remote keyboard, we have one. Some vendors make keyboards for the iPad that snap on. Frankly, this is what I want in a device. I use a real keyboard for input most of the time and it is far faster than the onscreen keyboard. Being able to combine a touch screen with a keyboard is ideal. At the desk or in one's lap one has a notebook computer's advantages. While walking around with it in the crook of your arm, reading at the table or in bed one has the advantages of just the screen. (Sure, there are other things to do in bed but how many times a night?)

  20. Huh? on Ask Slashdot: Teaching Chemistry To Home-Schooled Kids? · · Score: 1

    "He is home educated and doesn't read as well as schooled kids of his age."

    That is unusual. Homeschooled kids are typically far ahead of public schooled kids. This is a well documented fact plus I've observed it in all the homeschooled kids I know, including our three. You need to address this issue before worrying about the chemistry issue. Something else is going on.

  21. So Global Warming is good? on Earth Approaching Tipping Point Say Scientists · · Score: 2

    "Humans have already converted about 43 percent of the ice-free land surface of the planet"

    So if we have global warming that will free up more land from the ice reducing the percentage making Global Warming a good thing... Hmmm. Okay.

    But seriously folks, to give a historical example, here in Vermont and New Hampshire almost all the forests had been cut back in the 1700's and 1800's to make land for agriculture. Then due to the mini-ice age of the 1800's people left this area and the farms grew up to be forests again. This is real. Nature recovers the land if you don't keep it as grass lands. The beavers know all about this.

    I'll bet that effect will vanish in the future. People used to gravitate to the university towns for resources that are now available no matter where you live. We live way the heck out in the countryside and can get the same intellectual resources via the Internet that we used to have to go to the university towns to get.
