I guess I do not see this as being news for nerds but then a lot of Slashdot is not really news for Nerds anymore. I expect to see baseball scores to be the next addition to Slashdot.
Frankly I would love to see Linus have to actually deal with the real world sometime. If the biggest problem you have are unbalanced comments then you are living a charmed life.
You left out the third option. 1,100 jobs where saved by automation. Hostess went out of business and several other companies bought up the rights to the products that Hostess made.
Umm I guess the people that came up with this don't know much about aviation. Yes these would have a lot more drag and mass per payload than a regular airframe but best of all this has all been done before. https://en.wikipedia.org/wiki/...
"Yet they make it their business to collect it for their own profit, over my objections." Don't use their services. They are an advertising company and use public information plus what you give them to sell ads. So don't use Android, Chrome, Gmail, Maps, Blogger, and or GTalk. I really wonder what people are so worried about when it comes to advertising.As far as other issues I just do not send anything to private in any email system.
"Wow, your post doesn't make much sense at all." Do you have not read all of the the tread.
"Coloring the roads black won't help much when they're covered with white snow. If only we could draw electricity from somewhere else during the winter, which might be plentiful at that time if year." Except the idea I was replying to was this. "If a portion of the power might be usable to de-ice the roads? Perhaps before adoption as roadways, these panels might be put to use as sidewalks. " AKA maybe solar roads could deice themselves. Frankly the idea of wasting electricity to deice roads is just a bad one to start with since you are talking about a huge amount of power plus the cost of the heating elements. AKA you would be trying to heat the great outdoors.
"There is, however, quite a bit of solar energy available." Except that it does not follow the demand curve very well and is terrible in winter. The great plains and high plains are the best places for wind.
Wow.... Okay you want to use expensive solar power and then store it to melt ice off the roads... Since this is in winter you do understand that solar power will be in short supply right? And you want to build how many pressure tanks and turbines and pay for upkeep on the system?
Here let me make this really simple for you. Why not just make the roads black! The sun will heat them and keep them warm enough for the snow and ice to melt... Wait they are black and that is not what happens could it be that in winter not enough solar energy falls on the road to keep it above freezing?
Really people try and think WE ARE TALKING ABOUT WINTER! You have the least hours of sunlight and the sun is lowest in the sky and a flat plate collector that is probably covered with snow and ice to start with! Forget storage because it is not yet practical for large scale use yet much less for wasting it on ice removal plus it is winter when you have the least amount start with.
Solar power on roofs in Atlanta, Phoenix, and Orlando to help run ACs in the summer is a great idea. Solar roads to melt ice in winter is just DUMB.
This is almost as dumb as when someone suggested attaching a wheel with a generator to the back of an electric car to extend it's range.
"The solar panels contain a heating element, which should be able to melt ice and snow, as well as perhaps preventing damage from thermal expansion and contraction." So how much power do you think a solar panel covered with snow and ice would make?
I have a better idea. Why not make the roads black so they heat up with the sun that way you do not have cost of a solar panel heating element, Could it be that when you have ice and snow you do not have enough solar energy to melt snow and ice????
"I have solar panels that produce electricity on non-bright sunny days from morning to afternoon." Are they perfectly flat or are they at an optimal angle facing south? Also what percentage of power on a cloudy winter morning do you get vs say 7 am on cloudy winter day. And since the coldest temps at NIGHT and that ice often starts as SNOW how much would your panel make under snow and or at night... NONE.
"And I wonder if somehow the power might be stored some way. Naahhhh, that's crazy talk." Yea it pretty much is. The idea of using super expensive solar power then making it more expensive by having to store it to melt ice off a road is just dumb. It only makes sense if you have more power than you need and it would otherwise go to waste. Winter is when solar power is in shortest supply and in an area where you have iced over roads it would be in very short supply. You are without a doubt a big supporter of solar power and it some areas it does have value but you are refuse to see any of the problems and attack those that point them out. As to storage just look up a medium sized nuclear power plant and see how much power it makes in a year and then divide that out until you get how much it makes in 12 hours. Figure out how much you would have to spend on that many power walls and you will see the storage problem really quickly. then figure that you will have to replace about 5% of them every year after 5 years.
"College kids were out protesting the war in Vietnam, not buggy rides on the moon." College kids don't vote that much. It is not opposition that kills programs it is lack of support. When people started to complain that their soaps where being interrupted by coverage of moon landings it was all over. The issue was spending in general between the great society and Vietnam spending was out of control. Most people today don't really know history all that well but believe it or not Kennedy ran under the Missile gap. The DNC kept pushing for more spending for defense and weapons system and for running up a deficit. The republicans where trying to cut unnecessary military programs. For example the Air Force and the Army where developing almost identical IRBMs the Thor and the Jupiter. The Republicans told the Army that it was going to limited to short range 200 mile missiles and that the Air Force was responsible for the long range missiles. So the Jupiter was going to be cut but congress had a fit so the Air Force ended up with both! You can argue if long range missiles fit better with the Army or the Air Force but two almost identical systems that where both going to be very short lived is just dumb. You had huge spending on the military, huge spending on social programs, and huge spending on space. You cut the one that people will complain the least about. It became so bad that a common complaint became, "we can put a man on the moon but we can't..."
Solar in general is not where the funding should be going. Without storage solar will always be a highly opportunistic supplement. In the south of the US in summer it could help with AC loads but will still need to backed by lots of peaking plants powered by natural gas. Wind is better but the real investment should be in the next generation nuclear plants and honestly I would like to see more funding for some of the innovative fusion designs like the Lockheed high beta and the Polywell. Yes they are long shots but the pay off would be huge.
" but the 6502 was by all accounts just as good as the 6809." I suggest you take a look again. The 6809 was a much better cpu than the 6502. Just take a look at OS/9.
The Commodore 64 and the Atari where very good because of the advanced sound a graphics chips that they use. The Coco was stuck with less advanced sound and graphics chips but a better CPU so the sort of equalled out. The Apple II had the Woz.
The Apple II gs and the Commodore 128 where the ultimate 8 bit machines I would not call the IIgs and dead end as much as the end of the line. I would have liked to see a Commodore 256? that used the 65816 and HD64180 CPUs. No one would have bought it but it would have been cool. Maybe someday someone will make one using an FPGA.
Actually you should seek out Kennedy and Johnson. They got the US into Vietnam and before anyone posts how Kennedy would have gotten us out of Vietnam the facts are that at no time during the Kennedy administration did the number of US military in Vietnam go down. Nixon got the US out of Vietnam and as far as I know Reagan Except for some small actions did not start a war killing brown people as you put it. https://www.google.com/imgres?...
If you take a look yes Nixon and congress made massive cuts after Apollo because of the cost of the Vietnam war started by Kennedy and Johnson but it was still higher then Clinton and Obama. Reagan's funding level was also higher than Obama. Why the venom for those people?
Not really fair since the Itanium had lots of performance issues from the start. It depended on smart compilers that just did not work. It's one advantage was a large memory space and AMD took that away. It was one of two big fumbles that Intel made at the time, the other was Netburst. Yes people and companies usually want to buy a computer to run software, not software that may more may not exist in the future. I would love to see Intel for their Atoms drop the x86/286 support just to clean things up but I hear that really will not save much space on the die so it may not be worth it. Of course if Motorla had an inexpensive 68000 available and IBM had used it in the PC we would all have been much better off. The same is true if Apple, Atari, and Commodore had use the 6809 but the 6502 was also cheaper.
Would it actually be a lot longer? Often airliners will do a great circle route and stop in Alaska when going to Japan or Korea. It would be easier to maintain but I wonder if it would be any cheaper to run. After all the bottom of the ocean is free and you just need a ship to spool it out. It might be cheaper then running it over land.
I have to say that I do hate the reboots. Dear CBS Paramount you killed Star Trek but the fans kept it alive and ended up making it a cash cow for you. You blew it with ST:ENG. The reboots are terrible. You made the crew of the USS Enterprise into a bunch wack jobs and the new ship looks like crap. You better hope that the Fans save your cash cow for you again or just sell Star Trek to Disney they actually seem to know how to keep a franchise working.

Still? Maybe back in the 70s but today I doubt that most people know anything about it.

So from your data the idea of using a solar road to deice it's self is in technical terms dumb as a box of rocks.
The paying it to Google doesn't bother me at all. They offer great services I use everyday and I know how to control my own privacy,
"Yet they make it their business to collect it for their own profit, over my objections."
Don't use their services. They are an advertising company and use public information plus what you give them to sell ads.

Sure because ice always forms on roads on bright sunny days right around solar noon.

You don't know that you will hate them until you watched them. But I did not buy or rent the DVDs.

Makes me wonder why they do not run the cable up to Alaska and then to Japan. The total cable would be longer but less of it would be at sea.
