Now I know how to set up a LAN in an unwired munitions bunker...
As long as you are not planning to store munitions in the bunker....
While a lot of attention has been paid to safety in PoE, I'd want to make damn sure the implementation was sane before using it in a bunker. FWIW, I've actually worked in a couple of similar facilities.
Switch-mode power supplies are just as efficient with DC as with AC.
Switch mode supplies can be made to run more efficiently on DC than AC since rectification isn't required. Additional losses in an AC supply include diode forward voltage drops and ripple current losses in the input filter capacitor. Granted the difference isn't very big.
She is where she is because of her brains not looks.
She comes across as being unpretentious - more of the kind of woman that I'd like to get to know rather than a woman that I would be showing off to the guys.
Would you almost rather have the radioactive waste repository in your back yard as well?
Why not?
Properly done, the repository is far less obtrusive (mostly underground) and may present less of a safety hazard than a wind farm (think blades coming off the hubs).
The containment structure for the nuke plants also can be quite charming to look at - imagine the domes at San Onofre with the "caps" painted a nice pinkish red color.
Going back to an earlier analogy somebody made - when the USA asked the Afghanistan government to extradite people they claimed were responsible for the 9-11 attacks, they didn't offer any evidence and there are good reasons not to do so anyway - capital punishment, like you mention, and also barbaric treament like the running joke on this site, prison rape.
The 9-11 attacks were an act of war - there was a clear intent to kill and directed by people sponsored by the Afghan government. There was good reason to beleive that further attacks were coming (which did in fact happen in other countries).
Of course, it's not like India would be capable or justified in invading the USA, but it's a nasty case of double-standards, don't you think?
It would be a double standard if there was evidence that UC deliberately set out to create the disaster - by your reasoning several countries that had SARS deaths would have grounds for extraditing members of the Chinese government for suppressing news about the problem. It would have been a double standard had India prosecuted the people in UC of India and the local governments for their role in the disaster.
No. It's the
chairman that we are talking about here, and there's nothing stopping the government of India also holding the individual responsible in the government accountable.
Has the government of Bhopal provided sufficient evidence that the chairman of UC was legally culpable? Especially since UC is claiming that the release may have been due to an act of sabotage - a worker putting too much water into the methyl isocyanate tank.
Countries have the right to refuse to extradite one of their citizens for a variety of reasons - one would be the concern that the person would not receive a fair trial or face excessive punishment (e.g. many countries not willing to extradite to the US due to capital punishment). And many countries will refuse to extradite someone when the charges are not something that is a criminal offense in that country.
Has anyone in India been prosecuted for their part in the disaster?
Can anyone explain to me how Sun can open source Solaris which was licensed from SCO
Maybe because what Sun licensed from SCO was code for drivers and not for the Solaris Kernel?
ISTR that Sun had a much more generous license for the SysV stuff than IBM and I'd be really surprised if there was much of the AT&T SysV code left in the Solaris kernel.
The unofficial word from Sun employees (mentioned on Sun related usenet newsgroups) is that the money went to buy x86 drivers for Solaris. Since Solaris is SysV based, the drivers would be easy to rewrite for Solaris.
Perhaps the number 1 reason that Sun released the "Java" desktop system to run on Linux and not Solaris was the wider availability of drivers for Linux than Solaris.
Actually, in terms of the overall thermodynamic efficiency, they aren't all that great. 40% efficiency is *very* good for a Brayton cycle (i.e. turbine engine) system, but is fairly easily done with a large-scale steam system.
GE has an industrial turbine with a 46% thermal efficiency - this is a straight turbine, not a combined cycle. Solar has one model with a claimed 44% efficiency, achieved with the help of a regenerator. The high efficiency of the GE design is due to the compressor - an industrial turbine does not have to be as small as an aircraft engine with the attendant compromises in compressor design.
The best steam plants are barely over 40% (typical coal plant is now 33% due to emissions controls). They do have the advantage of maintaining high efficiency at low output levels. Steam plant efficiency has not improved since the 1950's when the supercritical cycle was introduced - steam becomes too corrosive when heated above 1100F.
I picked up a Gateway DVD burner in January - the i-Link just plugs in 1394 port. Cool thing about it is if there is a blank spot on the tape, the DVD recorder stops recording and picks up again when the signal returns.
The only thing new about the Sony box is handling two layer disks.
Air travel was well established by the time the Comet appeared on the scene, but the Comet crashes essentially pushed the Brits out of the commercial jet market.
The US had considerable experience with pressurized aircraft before the Boeing 707 - Boeing had the 307 (airliner conversion of the B-17), the B-29 and the 377 (airliner version of the B-50, which was a B-29 with P&W Wasp Majors) getting flight experience even before starting the design of the 707. Similarly, Douglas had considerable experience with the DC-6 and DC-7 before embarking on the DC-8.
Europe and the US has a history of never using each other standards. Just look at PAL/NTSC, NMT/APMS, GSM/DAMPS, Metric/Imperial, 110V60Hz/230V50Hz.
The US 110V standard was in place in 1882 when Edison set up the Pearl Street station in NYC - however it was DC not 60Hz (the last vestige of DC distribution disappeared a couple of years ago). I have seen a reference stating that the US picked 60Hz to be specifically incompatible with the European 50 Hz system - from a book on Southern California Edison, which was a 50 Hz utility until 1948! BTW, 25Hz was the standard frequency in the US for railroad electrification and found considreable industrial use.
This is more like a proposal from John Kraus (W8JK) of Ohio State - where he did propose making antennas for optical frequencies. In this case, Kraus was extending the rectantenna design for microwave power transmission to optical wavelengths.
Heinlein's idea was more along a generic resonator - in some ways he predicted LED's some 25 years before they were first made (Man who sold the moon ca 1940, LED's ca 1965). It is depressing to think that about the same amount of time has elapsed since the last moon landing and now as between when "The Man who sold the Moon" was written and the last moon landing.
An AC was nice enough to find this link for me that explained when the hull number was changed to CV(N)-6. The current Enterprise is simply CVN-65 with the "N" standing for Nuclear rather than Night.
I checked up on Friedman's Naval Institute Press book "Carrier" and much to my chagrin found that the original hull number for the Big-E was CV-6 and was the second Yorktown class ship. Interestingly enough, the Forrestal through the JFK were given CVA hull numbers, and the 'A' was dropped with the Nimitz. The Midway class were originally CVB...
No, I meant CVN-65. AFAIK, the Big-E always carried the hull number of CVA-6 - will check that out when I get access to my NIP book on carriers.
The first reference I saw for the Big-E was America Heritage's book "Carrier War in the Pacific" which I first read in 64 or 65 - it was also my first source for learning about the light carriers and escort carriers (the latter playing an important role in the Battle for Leyte Gulf).
FWIW, Roddenberry named the NCC-1701 after the Big-E as it had a record unmatched by any warship in history.
Bonus points in remembering when the Big-E was due into Pearl on the first weekend of Dec 41.
The USS Enterprise was originally given the CV-6 designation to demonstrate that she was a "Carrier Vessel"
Ummmm. The 'C' in CV originally stood for Cruiser, in part since the Lexington and Saratoga were modified Battle Cruisers. After the 1922 Naval treaty, the US scrapped a bunch of battleships and battle cruisers under construction, but did get to convert two into carriers. Incidentally, CVA-2 and CVA-3 had turbo-electric drives.
The Enterprise's were CVA-6 and CVA(N)-65 ('A' was for Attack), and the latter was changed to CVN-65 when the Light (CVL) and Escort (CVE) carriers were no longer part of the USN's plans.
Yes, but the $20 to $50 per foot of wiring has generally already been installed.
True for power wiring but not sensor wiring. As someone else pointed out, the main cost is the labor of installation.
Existing process control systems are concerned with the process and not necessarily the equipment - you may have transducers to report motor power consumption, but those won't necessarily tell if the increase was due to process problems or a motor bearing about to fail.
The folks working on this are very aware of the problems with interference - DOE has been working on factory floor networking for several years (Wayne Manges from ORNL). In addition to interference, you have to contend with Dopler shift and fading as a result of objects moving aroound the floor (variable multipath). For those with radio experience (e.g hams) signal propagation starts to look more like HF (shortwave) than microwave.
but retrofitting is going to be a big flop
Actually the whole point of this work is to retrofit the factory floors (or other places using large motors). According to Wayne Manges, you're looking at $20 to $50 per foot to install wiring, so a $200 wireless sensor would be cost effective compared to running wire. The system could pay for itself by flagging one motor that is having problems before it fails - DOE's hope is that you can also tell tha the motor is chewing up electricity at an excessive rate.
One big difference between running Linux binaries on Solaris and Windoze binaries on OS/2 - Microsoft changed the Windoze ABI slightly after the agreement with IBM ran out - so that it was possible to write an application for Win 3.11 that would not run on OS/2. Since the Linux API and ABI is open, Sun is free to modify the Linux translation layer as necessary to maintain compatibility. Also remember that the whole reason for "Linux Standard Base" was to have a common ABI for LSB compliant distro's.
The benefit for Sun is that there are a significant number of Linux applications that do not come with source.

Extra points if you remember the short story published in Analog about 15 years ago.

And... How about being subject to property tax? California, for one, could use the extra tax revenue.
Don't you mean that Microsoft Windows has been around almost excatly as long as GNU.org???
Microsoft started ca 1976, MS-Windows 1.0 announced late 1983, GNU manifesto published in Dr Dobbs in 1984.
And Sun isn't??

Umm, don't you mean filing 10 patent applications a day?
I would hope the US PTO isn't so hard up as to automatically grant every application filed by M$.
