Also good for delivering stuff into the Moon's gravity well... which is something you'll want to be doing from time to time. Delivery vehicle stays well out in space, doesn't have to waste energy getting down and getting up again. More efficient than parachutes.
Better still (and requiring no reprogramming): create a separate contact list with a million random email addresses and never use it yourself. [Either use a separate category, or create an Outlook Express list when you never actually use Outlook Express yourself or a Eudora list if you never actually use Eudora].
If it gets harvested then it reduces the value of the harvested list (arbitrarily close to zero, if enough people do this).
If a worm on your own computer tries to use the list then there are all sorts of possibilities: you may just reckon on noticing if that many emails are being sent; you may find a way of monitoring outgoing emails and immediately halting transmission if one of the addresses gets used (a good new feature to add to antivirus software); or you may include "canary" addresses in that list that will cause you to be alerted when they're used.
No, the market wasn't inelastic (zero elasticity). The elasticity was negative: the higher price increased demand. This is actually quite common, and not only in software, since price is a principal indicator of quality. Double your price and you will quite often increase your unit sales.
What puzzles me about this beautiful and concise explanation is that there is no such thing as a field line: they are mere abstractions. And yet your description (which is in line what physicists generally tell us) talks as if they were material objects under tension, with elasticity and so on. Naturally this metaphor must be justifiable by reference to the underlying electromagnetic theory, but is there any concise justification of this anywhere?
The procedures have evolved over the years as follows:
There's a fire in the left engine and you have to shut it down in a hurry. So you yell LEFT. You thump the LEFT side of your head. You wave your LEFT arm. Pilot and co-pilot both.
Even so, there have been times when the left engine was on fire and they shut down the right one.
... divided people into "honestiores" and "humiliores": penalties were greater for the former.
In fact this is surprisingly common throughout history: a correlative of the variation of weregild depending on the status of the person harmed/killed. Until the professionals got in on the act, justice did more or less mean justice.
Mainstream operating systems were designed when electronics were expensive and programs had to treat the computer system as a shared resource. Hence timesharing, multitasking, shared filesystems, and the rest, with all the combinatorial problems of N programs interacting with N other programs.
Now that CPU-plus-memory is so much cheaper, do you see a phase change coming where it is better/more secure/simpler to have one CPU per application? What impact would this have on operating system design?
How much energy would the USA save by switching from 110VAC to 220VAC power distribution? It would halve the ohmic losses in local wiring and would also reduce the amount of copper used. Since the rest of the world uses 220V, it would also simplify equipment design.

There is actually nothing in SR to stop you travelling to Prox. Centauri in a week. The catch is, it would have to be your week, not ours.
In our rest frame, your journey would take over 3 years and be over 3 light years long; in your frame (travelling at a speed, relative to us, of close to c) your journey time would be a week (time dilation) but also, in your frame, the distance to Prox. Centauri would be less than a light-week (space contraction). "How much of your time will it take to travel X light years if you accelerate at 30ft/sec2?" is a standard undergraduate exam question.
The constraints are really energy (getting a rocket powerful enough) and not relativity. Science fiction writers tend to use hyperdrives because even if travel takes only a short time for the traveller it's difficult to get a plot working if the travel takes years or centuries for people in rest frames.
... when any scientist could publish to more people, faster, cheaper? Because Nature does the work for the reader of selecting what is worth looking at-- both by peer review and by editorial policy. That's what you're paying for: not the actual printed text. So how about this: publish all papers free on the Web but ban any mention of whether they're also published in Nature? [since it's not fair to freeload on the value that the journal has added] A different Modest Proposal: use Slashdot to publish scientific papers. It already has an incorruptible peer review system after all.
Not true that requiring a reboot means the installer is doing something dodgy - at least, not true when you're upgrading already installed software. Windows (EXPLORER.EXE) regularly holds application program files open for no reason at all (I suspect it's something to do with displaying icons), so a reboot is the only way to replace an out-of-date file.
260 sq.km = an area 10 miles square. So don't drink the water and stay out of the area. Bingo, you have a nice big nature reserve that you can guarantee won't be invaded or built over by people. What could be better for wildlife and the environment?
I sell Windows software. Microsoft is dying and I want to get out. I will port my software to the Linux GUI when such a thing exists. Gnome isn't the Linux GUI, because there's KDE, KDE isn't the Linux GUI because there's Gnome. As a user, I will move to Linux when there is such a thing as Linux software. Linux software is something that runs on the Linux GUI. But until there's such a thing as the Linux GUI...
It wasn't safe to be a Jew in Muslim Spain either. The philosopher Moses Maimonides had to flee Spain to avoid attempts to convert him by force. He fled to Cairo (1159) where he became head of the Jewish community in Egypt. On the other hand, Avicenna (Abu Ibn-Sina, the greatest mediaeval Muslim philosopher) had his books burned and barely escaped with his life... because if something's already in the Koran, there's no need to say it again, and if it isn't, then it's false and mustn't be said. See (eg.) Huff, The Rise of Early Modern Science.
So how much copper, approximately, would the USA save by moving from 110V to 230V? And how many MWH of power would be saved, per year, by the reduced resistive losses?
Bring the USA into line with the rest of the world and use 230VAC instead of 110V. This halves the current through the wiring, thus halving the power wasted. And cables need only half the copper for the lower current, saving raw materials into the bargain.
If you use your own SMTP server, you get rational standard 3-digit error responses when (eg) the recipient's email is invalid, mailbox full, whatever.
If you use a smarthost, the error response is wrapped up in a verbose email, so you have to implement automated handling, parsing, error code extraction, working out which email address it refer to, and all the rest.
If you could scan & post (with lossless compression eg. GIF) a couple of vaguely typical pages then we could all try our favorite compression software on it & get some idea of how much storage could be saved.
Secret algorithm, "unbreakable cipher", "unprecedented levels of security", irrelevant details but no relevant ones, all the rest that you expect from crypto snake oil. No apparent knowledge of or reference to the state of the art; no understanding of why "keyless" encryption might be a bad thing; no apparent advantage over Diffie-Hellman key exchange (and D-H doesn't expand messages by a factor of 50). This is not to say that their other products might not be worth something.

No. Viruses are small. Applications are big. It's easy to write bug-free small programs.

I remember reading an article about ELF in Wireless World in 1970 - but it could have been VLF, I suppose. Anyone on here old enough to comment?
Hidden away in the article is a discovery that will revolutionize our understanding of particle physics and cosmology:
This must imply that there exists a lighter lepton than the electron. Goodbye, Standard Model!How much energy would the USA save by switching from 110VAC to 220VAC power distribution? It would halve the ohmic losses in local wiring and would also reduce the amount of copper used. Since the rest of the world uses 220V, it would also simplify equipment design.

If you can save Word documents in XML nowadays, doesn't that mean you can manually look at the XML file and see what is "hidden" in your document?

The things you list didn't happen live on television and they didn't involve Americans.
You could add the current genocide in Sudan to the list. Sudan has no oil.
Bring the USA into line with the rest of the world and use 230VAC instead of 110V. This halves the current through the wiring, thus halving the power wasted. And cables need only half the copper for the lower current, saving raw materials into the bargain.
