Metal Halide light outdoors (available at Lowes, but not Home Depot, last I checked) make good outdoor driveway lights and the light with much better color rendering than the old sodium light and excellent energy efficiency as well. It would be nice to get LEDS, no doubt, but the lumens output and price just ain't there yet. Hopefully these type of developments will change that.

    While all the hoopla is around lighting these days, that only comprises about 10% of a houses electrical energy use these days, IIRC. So your max savings is 10% -- a good and worthy start but not enough. Many electrical devices are already operating at high efficiency (electrical motors for instance) so many appliances can't be improved. Other devices just need to be used less (washer, dishwasher) through conscientous use, and things like Computers just need to be set correctly for energy savings on the software level (or make sure things like Printers come with their own print server rather than have a computer act as one... sometimes it's good to get a router with a harddrive as well...

    But all this doesn't change the fact that most houses themselves are built to use way too much energy. Until that is solved, the other problems are at least orders of a magnitude smaller:

    Windows does not compete with Linux distros like Ubuntu (for example, as being the friendliest to newbs) in many areas.

    The one inherent advantage Windows has is in the big name and industry niche applications written for it (Linux wins hands down on small size apps normal people use day to day - for instance k3b > nero). If the big name apps were ever to migrate their software, I could forsee big troubles for Microsoft. Today looking for tax software at Walmart, I saw a dozen different packages produced by 3 competing reputable companies (Intuit, H&R Block, forget the third). It would take only one of those companies to see Linux desktop as a great untapped market and transfer their product to it to start the slide in that area.

    And with Walmart sucessfully selling low end Linux PCs, I could see that happening. When? I don't know. But Vista helped. I have it, I run it. It's okay on a powerful machine but it uses too many resources out of the box compared to Ubuntu. Thus people can get cheaper machines to check their email and surf with Ubuntu on it.

    So many small businesses/people tend to stick to Windows because of just one or two apps as well. I know several business that just used Quickbooks and/or ebay's Blackthorne that would love to get off of windows if a decent alternative was present. For some, that alternative is available today (not true many years ago when websites were IE only). For others, they'll have to wait.

    Hmmm....

    I don't know if it's getting smaller. The notebook market is increasing every year. Although I'm sure a lot of those are low-end laptops that trend won't hurt the high-end ones except marketshare % - Apple supplies about 15% of the notebooks sold in the US and their cheapest is over a grand.

    It's not that I disagree with you. But the reason I don't buy multiple computers as you suggest is because of power consumption - even 24/7, laptops use much less than the traditional PC. Since I live in an area with one of the nation's highest electrical costs (close to 20 cents a kwh after all the surcharges tacked on) it is a longer term concern for me beyond just initial costs.

    Once I'm done with the notebook, it will get passed on to others in the family and having 5 laptops with correctly programmed sleep/hibernate is much less of an electrical hit than 5 PCs where those are afterthoughts (at least years back).

  15. Older recruits? on Ask the Air Force Cyber Command General About War in Cyberspace · · Score: 5, Interesting

    It seems that in the military traditionally it was always looking for people fresh out of highschool for EMs and if you wanted to get anywhere in the military you had to be either college educated or, to really have a high end military career, start really young in something like the Valley Forge Military Academy and work from there.

    In a traditional branch of the army/navy/airforce that is probably as it should be.

    But in this area people have to be trained for years, still not know as much as the older hands in the private industry, and before they really know enough their enlistment would be over. Also, it would be unacceptable for an older IT person to join but take a pay cut to a Private's level or perhaps even a Lieutenant's -- so I imagine this branch would have to be somewhat different.

    Is the military going to do to reach out toward the older folks who have extensive experience and knowledge outside the military?

    The same way a chef may buy a set of knives that cost several hundred dollars instead of a set that cost $50 - because it's worth it to them. The better knives may cut marginally better at first but the real secret is that they hold their edge a lot longer.

    I would conjecture is that it's not a plan from top, it's just a result of there being a nice, proper way to do things and a quick n' dirty way and Apple engineers have the quick n' dirty way down in the few parts due to access to the code. That's all.

    I hate the idea because the idea of property taxes are repugnant to me to begin with. Look, not all your property gets taxed either - would you like having to pay yearly for the stuff you own? I don't like the idea that the government so thoroughly owns everything that they can even take what you "own" for ransom and make you pay a yearly rent on it. It makes me sick to my stomach when I think about all the elderly people I knew who had to move out of the home they owned for XX years just because they didn't have the income to pay property/school taxes.

    I much prefer an excise tax to pay for things.

    However, another tax is not the answer here either. A massive bureacracy will have to be built up to keep track of these thing and calculate the taxes - I mean how do you even begin to calculate such a thing to meet the propose purpose of the summary? - which I assure you the major corporations will find the right accountants/lawyers to underpay while the small business owner suffers under more paperwork.

    A bad, stupid idea. Only the government would love it where it decides it will tax others to fix the failings of its own original bad system it imposes on the rest of us.

    Isn't that the draw only in idle mode? That, when active, it's slightly higher?

    Still, when running I read the screen uses 2W instead of the typical notebook LCD 25-35W. And it's also readable in daylight (alas in B/W). The rest of the savings come from it being a relatively low performance CPU and the SSD harddrive.

    Why can't the 2 grand Macbook Pros have this screen? Or any notebook for that matter? I read that the OLPC leader refuses to commercialize the patents, but that seems myopic on his part -- he could be doing something for the environment (less electrical use all around) while directly financing his project and making the economies of scale really work if everyone starts producing these for notebooks/desktops/TVs/etcetera.

    A green PC would be okay but for many cases it saves more overall energy if people stick with their current PCs as long as they can instead of throwing them out after a few years. For the typical home user, strategies as setting them to go on standby or, better yet, hibernation after 1/2 hour helps a lot. Unless it's a server of a type, there is no need to keep any of them running 24/7. Try consolidating several servers onto one computer. These also can be set to go off and on at certain times in the BIOS. No need to keep a file or print server running in middle of the night in most cases. Most modern printers also connect to ethernet directly these days which can completely cut out a print server and some routers have harddrives that act as file servers that use much less energy than an entire computer.

    Anyway, most home users will probably affect the environment more if they switch from incandescent bulbs to CFL bulbs. It's cheaper too, and you recoup your investment between 2 months to a year.

    Notice that music didn't move to Music DVDs. It went straight to digital.

    If HD-DVD were serious about winning the format wars, they should have tried getting a burner to the market as fast and cheaply as possible. Hi-end computers would have started shipping with them and people with money to burn would be buying HD-DVD that they could rip to their harddrive as well.

    Even though I can get a HD-DVD/Blu-Ray drive, there is absolutely no incentive for me. I'm sure DVDs are good enough for the vast majority of the audience as well for the time being.

    If Blu-ray will win for any reason at all, it was because people would have bought PS3 anyway. Otherwise it would have stayed a niche product like Laserdisc.

    And DVD would have kept it spot (is keeping its spot) and 5-10 years down the line some digital/internet solution would have been agreed upon by the major studios. Itunes is attempting it already.

It's seen in many rich families too - the 1st generation works hard and brings in the billions, the second generation generally doesn't have to work quite as hard but enough to keep the empire afloat, and the 3rd generation tends to squander the luxury they grew up with. You can see the same trend in successful immigrant families as well.

    Nationwide -- just look at the deficits being run up this year (3 trillion dollar budget!) -- the politicians are directly mortgaging our and our children's future for some frivolous spending today -- and there will be consequences even though they seem distant -- extremely high taxes or high inflation wiping out the middle class.
