The real privacy concerns to me are whether the NSA is sharing this information to be used by others for purposes other than those used to justify the monitoring. For instance, if they hear that I have a real big order of yeast and barley malt enroute from one company, and a lot of lab equipment on order from another company, will they alert the ATF that I have just ordered the necessary ingredients and supplies to start distillng alcohol? Although illegal where I reside, a still is not a security risk, and passing on that type of information seems to me to be the greater privacy risk, and goes against the whole reason for the monitoring in the first place. Of course, others may disagree, and no, I don't have a still.
I definitely agree that it is stupid to use a chip with such a flaw.
I agree it could be deadly.
US Federal Aviation Regulations, if followed, might prevent the deaths, though. At altitude, either the pilot or copilot is supposed to be on oxygen full time. In the event of a rapid decompression, that person would be able to descend the plane to an altitude where the pressure is great enough for all to regain consciousness.
Unfortunately, at the lower altitude, the fuel flow would be a lot greater for a given distance, and if the plane is on an extended overwater flight, the plane may not make it to a safe destination, especially since the four-engine design exempts it from ETOPS.
If anyone who has their ATP license sees anything incorrect, please correct me.
But it would be a huge spike and they'd probably need to get extra staff, pay overtime, for something there is no need for such a panic.
Agreed for the most part, but I think they would increase part time hours rather than go to overtime.
More importantly, physical distribution of books is what distributors do; their costs are already paid basically -- their trucks are making deliveries on, say, a weekly basis, regardless...
And there is where the problem lies - if Fedex or UPS can deliver on a just-in-time basis, or pretty close, why should a bookseller pay for storage space that could be used for retail space just to allow book distributors to deliver at their convenience, which is a weekly basis? Is the cost advantage that great? Or, do the publishers and booksellers plan on selling such a great number of books in such a short time that UPS/Fedex just-in-time service is impractical? (Really, I don't know, please enlighten me.)
The millions of books doesn't matter as much as the thousands of locations, since all of the books going to the same location can go in one package, so we are really only talking about thousands of packages. Fedex was able to handle 800,000 packages one day during a Christmas shipping season before they bought out a ground operation to compliment their airborne delivery. I really don't think they would have a problem with the task. UPS handles the warehousing and shipping operations for several companies; I'm sure they are up to the task as well.
If you don't want a book to be sold until a particular time, don't ship it to resellers.
You hit that nail right on the head. With today's shipping services, you can pretty much guarantee a specific delivery date. Shipping early and forcing retailers to hold back stock for the sake of hyping a release date is one of marketing's most assinine (sp?) behaviors. Although I see the logic from a business point of view, (if the product sucks, you still have a large first-wave of buyers before the word gets out,) it still sucks for the retailer and the consumer - the retailer has to use more storage space, and the consumer can't buy the product which is already in the store.
If music/book/movie publishers would consistently put out a quality product, maybe this market hype wouldn't be needed. I won't hold my breath for that to happen, though.
I believe the FAA regulations involve creating the sonic boom. It would be hard to operate in controlled airspace (about 18,000 feet to 60,000 feet) at a supersonic speed due to conflicting traffic, boom or not, but above 60,000, it may be okay, provided that it could be done without the boom.
I had to do a paper (upper level undergraduate) about the costs and benefist of supersonic aircraft. From what I remember, the costs of constructing a supersonic aircraft were about 3.3 times the cost of a subsonic aircraft with the same load and range capabilities. When you consider the finance charges and risk involved, it may not be financially feasible for many carriers to invest in supersonic travel if the costs are 3.3 times as high.

I have noticed the same thing that you have, (married generally more productive than single,) but when I look at age instead of marital status, I notice the older folks are generally married, and the younger folks are less likely to be married.
If I look at it as an age issue rather than a marital status issue, I get a better correlation, (older more productive at a given job than younger,) with young married folks being the least productive. Young singles tend to have the greatest deviation (occasionally the most productive, but also occasionally the least productive,) but on average rate better than young married folks.
The above observations are just my personal experience, and others may have a broader database to analyze.
I agree with you. Unfortunately, many public schools in the US fund/budget the programs for all disorders of this type as Autistic Spectrum disorders, even if the symptoms of that child's disorder are the exact opposite of true autism. This creates problems when the few uninformed/unaware educators in the system are assigned to work with special needs children, as they may treat all kids being treated under Autistic Spectrum disorder programs as Autistic. Luckily, educators usually assigned to work with special needs children know the difference. When they do not, it can be frustrating to try to explain that what works for an autistic child does not necessarily work for a given child with an autistic spectrum disorder.
...but I really have a hard time believing that by "rather different from the TV version" he meant "absent of the type of humour that is normally associated with the Hitchhiker series". I could be wrong, though, since I am not a clairvoyant.
If the reviewer is accurate, (and I have no reason to doubt it,) this movie is nothing like Mr. Adams would have wanted.
I believe Douglas Adams once made a comment about how good humor was a gift to the intelligent - those that weren't intelligent really didn't understand it. Judging from the long review, this movie isn't aimed at an intelligent audience.
I guess I'll wait for it to hit video (maybe late May,) and rent it on a day when I want to punish myself and feel bad.
I understand that the marginal cost of putting an object into space would be lower once the elevator is constructed. I haven't seen anything that addresses the costs of construction divided among the number of expected launches, however.
For example, if the space elevator would last 100 years, and it cost $36,525,000,000 to construct, (probably a low estimate, but I am no expert on costs to transport masses to geostationary orbit or the required mass of the space elevator,) and could perform one lauch per day, that would mean the construction costs would add $1,000,000 per launch, which would still be a bargain. If their are not enough customers to support one launch per day, the allocated construction costs per launch rise. If the total construction costs are greater, allocated construction costs per launch rise. If the life span is shorter than 100 years, allocated construction costs per launch rise.
I believe that these economic aspects will doom the space elevator. I could be wrong, though.
I think this is where the problem comes in. It is not an inexpensive task to construct something from a point in geostationary orbit. All materials would have to be put in an orbit at that point, as well as crew/robots etc for construction. For the cost of construction and operation over the expected life of the space elevator, could we put the same objects in orbit using convential methods cheaper? If so, why bother building the space elevator? I am by no means an expert on the space elevator, but considering the physics of construction, I don't believe it will work out to be cheaper on a per launch basis.
Of course, others' opinions may vary, and I am sure some will have methods to ignore conservation of angular momentum and orbital mechanics to come up with construction techniques that do not require a geostationary orbit starting point. Unfortunately for me, I am not educated enough yet to figure out how to construct a space-elevator without starting at the geostationary orbit. Please enlighten me if you know how to do this.
4. Subject Vonage and other VoIP services to the same QoS minimums that ILECs are currently subject to
I have a home in Texas with SBC providing phone lines (most of the time - sometimes we have to go without). Still no DSL service to that area, and it isn't forecast to be installed anytime soon. It takes a couple of days for crews to check on line problems if it is a single home, during which time that home has no 911 service. I have had to jump into neighbors's yards to repair lines that came out of the ground and were weed-wacked to be able to use my own phone. The only company with worse service was Charter Cable, who took a month to fix a problem when an improperly installed line-filter took out cable internet for the whole neighborhood.
With this in mind, it is my opinion that making other providers meet the same quality of service as SBC is like making all operating system software meet the same security level as Windows 98 with Outlook and Internet Explorer, but without antivirus. Others may have different experiences with Windows 98 or SBC, but I hope you understand my point.
Maybe a better idea would be to make all providers, SBC especially, meet a higher minimum level of service. 911 doesn't do any good if you can't call them, and it is severely degraded if they can't figure out where you are when you do call.
From the Article: "Server operating systems are largely commoditized," DiDio said, adding that many companies were not tracking their operating costs closely enough to base their decisions on total cost of ownership, or TCO, the main cost metric when comparing Linux and Windows.
So, they ask the bosses "What is the TCO for Windows-based servers?" "I don't know"
Then, they ask the bosses "What is the TCO for Linux-based servers?" "I don't know"
Since "I don't know" equals "I don't know", the conclusion is that the operating systems have equal TCOs, at least in the eyes of the business managers.
He didn't like UNIX much in the service because he said their equipment didn't work well often.
It may be that the applications written for the UNIX boxes were the problem. Windows doesn't have a monopoly on poorly written applications. If a application uses a lot of the memory and dives into a memory hogging infinite loop, it isn't pretty, whether it is a Windows box or UNIX box.
It could possibly be the hardware itself. The military often has their computers in places that aren't the most hardware-friendly environments.
It could also be poor documentation. If the documentation is written for a comp-sci grad, assuming that obvious points that would be obvious to a comp-sci grad are known, the rifleman fresh out of high school/boot camp will probably have a few problems with getting the software to do what he wants.
I couldn't find a good linkable reference, but I think the 25 fatalities on an Ilyushin 18B at Guangzhou-Baiyun airport in 1982 was also caused by a fire started by a cigarette.

The statistics in the news article show time online in February 2005. I would expect a decline in time online compared to February 2004, since February 2004 had 29 days and February 2005 had 28 days.

BOOM occurs continuously as the craft is traveling at speeds greater than Mach 1, not just when the craft first exceeds Mach 1. It is not unusual to hear BOOM BOOM or BOOM BOOM BOOM if the craft is low enough.
Now retailers can build boxes that can be sold to the public with either Intel or AMD CPUs without having to carry different motherboards for each. This would be great for the places that make low-end to mid-price systems for those who are afraid to open their cases.
I don't think most folks don't know as much about the branding of their motherboard as they do their chipset. With this motherboard, the customer can come in and say "I want AMD" or "I want Intel" and get basically the same setup. This reduces the inventory of the retailer without reducing sales, which would theoretically increase profit, all else being equal.
