It seems complex because it IS complex. You've boiled an extremely complex problem down to "all you have to do" and "simply"! I'm sure Argonne National Lab would love to hire you.
This has been a topic of research for over a decade at ANL, and they publish their work as the "GREET" model.
The industry term you're looking for is "MPPGE" or miles per gallon gas equivalent, which is a best-effort to compare different drivetrains with a common number. It's far from accurate because there are a vast number of variables that can be taken into account, but it's a starting point, at least.
Simple, diesels are dirty by nature and are expensive to make clean and acceptable for California emissions standards. Dollars per horsepower, once you factor in emissions, gasoline still wins on the up-front costs, by a lot. Newer direct-injection engines are approaching diesel efficiencies, too.
Depends on how you define Green. California has for the past 30 years been focusing on Air Quality ("Smog"), which actually has less to do with fuel economy and CO2 emissions and more to do with the other combustion byproducts. From California's perspective, a 2-stroke moped is orders of magnitude worse a polluter than a Prius.
Passenger cars are held to much higher emission standards than trucks. California has the strictest air quality standards in the world. (Air Quality != CO2 emissions).
Diesel cars that are sold in Europe do not usually have expensive exhaust after-treatments, and those models are too dirty for California's emissions regulations. From an air quality perspective, diesels are orders of magnitude worse than hybrids. In particular, NOx (Nitrous Oxide, smog public enemy #1) and particulate emissions are the problem. Once you add the equipment required to meet those regulations, the cost far exceeds any fuel benefits you'll see, coupled with higher-than-average Diesel fuel prices here.
What doesn't sell in California doesn't get made for the US, since Cali is more or less the top car market in the country.
There's been some advances on clean passenger diesel engines--the VW Jetta is available now in the US market with their TDI diesel engine (for a $5,000 premium on the base model). I think it was the first passenger car to meet this, not sure about the other makes...
NOx is a major source of smog problems; VOCs are extremely common in nature as most plants give them off to some degree. Ever smell a cut fruit? Those are VOCs, too. California has enough VOCs that NOx is directly responsible for the smog. Not to mention its other problems, including its role as a greenhouse gas and in acid rain production...
Consider this case. Say you're a company that needs to invest in 200 copies of a high-end piece of software that costs $5000 a seat. You're now looking down the mouth of a $1,000,000 bill that needs to be paid off in 30 days. This can be upsetting to your accounting folks. Now consider the lease option. Microsoft basically lets you finance your software licenses at a cost of something on the order of $10,000 a month, which is much more palatable for your accountants to manage throughout the year. Best part is, if you hire an additional 50 workers, you can just bump up the lease instead of paying out another increment of $250k.
Also, sometimes leasing things works out more favorably than owning in accounting.
This type of licensing makes no sense for personal use or small quantities of licenses, but on a large scale, there are potential benefits for customers over paying the full price up front.
Wrong. Diesel gets higher mileage because 1) It has more heat content 128,700 Btu/gal (net) vs gasoline 115,400 Btu/gal(net) (~10%) and a more efficient combustion cycle that wastes less heat (while the gasoline Otto cycle could theoretically be more efficient, current practical Diesel engines are several percent more efficient because of their very high compression ratios). The high torque at low revs is a nice side effect.
Diesel still has the emissions problem of higher Nitrous Oxide (high compression ratios = higher heat = more oxygen binding to nitrogen) and particulate emissions (smoke) than gasoline. Diesels contribute far more to smog than any modern gas engine. The new US 2008 Diesel standards will help with this, but the required after treatments are adding cost and problems to production vehicles for no tangible benefit to the consumer.
Apple and Bose maintain tight control over their distribution. As such, they control directly the price the retailer pays for the goods. Other companies use third party distributors which introduce more padding into the pricing, and as such more flexibility. If you violate Apple's pricing policies, well, no more iPods for you to sell, and you can't get them anywhere else for less than the retail price. With other companies, you could simply call up another distributor and continue selling the goods for whatever price you wanted (even if it's below retail).
The practice of selling things too cheap will lessen as more and more companies take control of their distribution, cut out distributors, and enforce their pricing policies.
MSN cheats a lot -- every time you type a wrong URL into an IE browser, it brings up an error page served from MSN by default. Not sure what percentage of traffic this accounts for, but I bet it overinflates the figures by at least 100% from users actually wanting to go to MSN.
Perhaps attendence is down because of the internet -- not piracy, but word about crappy movies gets around a lot faster than it used to, so people avoid them more readily.
Am I alone here in thinking that this article is written by a 13-year old? While I respect the fact it's an "editorial", it is riddled with name calling, over-used cliches, and a dire lack of supporting facts. It seems the author is beginning from the "I HATE INTEL AND EVERYTHING NOT LINUX!" stance and going from there. Could someone point us toward a more objective evaluation, or at least a less childish editoral of this new platform?
If you're buying just plane tickets from Expidea, Travelocity, or Orbitz, 9 times out of 10 it's cheaper to buy the ticket directly from the airline in question. Cut out the middleman.
I can't help but recall the movie Running Man when reading this... Next thing you know, the bracelets will blow your head off if you try to remove them. Now THAT's a detterent!
$1 BILLION though? Gimme a break. Put the money toward drug rehab programs and decriminalize lighter drugs. Save everyone some cash.
Ah! There is one CRUCIAL difference between internet radio and traditonal broadcast: there is no limited bandwidth for Internet radio. There CAN be 10,000 stations coming into your computer, and none of them are using a public resource -- airwaves in this case, therefore they SHOULDN'T be regulated.
Old radio had to be regulated because there was only room for 20-30 stations in each market. If a new station popped up, and broadcasted over the old one, then that station is essentially put out of business. Meanwhile, on the internet, a new station pops up, and affects nobody else's station. Therefore, regulation is not needed.
The airwaves are one of the few cases where government regulation is truly needed to maintain order and "fairness". The internet does NOT need regulation.
God help us if they do attempt to regulate internet radio, (or any internet service for that matter) but it's an impossible task. Everyone will simply move off-shore to where it's "legal".
What are the costs of impementing this system and maintaining it? I suspect they are a heckuva lot higher than the current tax system where you just get your check from the oil distributors. So, once you implement it, you're actually making LESS money and have to charge even higher taxes to pay for the damn system and the burearucrats to run it.
Idiotic and stupid. Keep it the way it is. This flies in the face of California's environmental policies. Why not spend a few minutes and see where you can cut back spending (hint: stop giving non-taxpayers any money at all (read: illegal immigrants)) instead of wasting time AND money figuring out how to cripple your citizen's income?
I hope Arnie squashes this before it gets out of hand.
My immediate guess is that the vast majority, if not all of these balls would fall out of orbit and either burn up in the atmosphere or fling out into space, depending on which direction they leave the bomb...
Unfortunately, the issue of contamination remains. If a Columbia-like incident happens and this thing disintigrates mid-air, you've just scattered radiactive material over hundreds of miles in the atmosphere. This is why most nuclear space projects haven't been pursued.
I'd imagine this system would only catch / bring attention to small timers and reckless teenagers who probably don't pose much threat to the government. Any group that is serious about inflicting harm would probably meet in person and work out a simple code system to make their conversations slip through the cracks of this system (ie: "Monkey" for "President", "Birthday cake" for 'bomb', etc).
I'd really love to see a listing where the budgets of these movies are factored in, for bost best and worst. I think that would yield some interesting results.
I tried gaim for windows a while back, but the performance of the app is pretty rough. Very slow screen updates, and lots of bugs, especially on a machine that's not a multi-gigahertz one.

This might be obvious, but take a close look at the authors of the article:
Dr. Robert B.K. Dewar, AdaCore Inc. (President)
Dr. Edmond Schonberg, AdaCore Inc. (Vice President).
The article by some weird coincidence slams Java and praises Ada.
Salt, please...
PS, Ada is mainly alive in the Military/Aerospace industries where projects can last 20+ years.
