Modern schemes wouldn't be necessary because quantum cryptography would become the standard and is proven to be unbreakable by the laws of quantum mechanics. Any interaction (malicious or otherwise) of a third party is noticable to the proper parties and the message/key transmission is just repeated until a clean send is achieved.
Well, that's fine for communications, but what about data stored on your computer's hard drive? How will you be able to encrypt your illegal pr0n^W^W personal data so that only you can access it?
If you don't know how to do all your own repairs, you don't deserve to have a car.
If you can't install it yourself, you shouldn't have cable.
If you can't put it together yourself, you don't deserve to have a computer.
If you can't build it yourself, you don't deserve to have a house.
If you can't cook it yourself, you don't deserve a gourmet meal.

Today's WYSIWYG editors are equivalent to an automatic mechanic, automatic cable installer, etc., in your examples, which are poor analogies. I'm not saying that there is no place for WYSIWYG editors; it's just that you aren't going to get quality web pages with them. To modify one of your examples, it's like "If you can't cook it yourself, pop a TV dinner in the microwave". The current crop of WYSIWYG editors (that I've seen) are the TV dinners of the web world.
This is not to say that WYSIWYG editors are always going to be bad. An editor that I might use would have at least three windows:
Raw HTML/XHTML/XML with syntax highlighting, a vi/vim/gvim interface, and semi-automatic validation.
CSS/XSL style sheet.
The graphical output (or audio output for the visually impaired, etc.).
Other handy windows would be DTD/XSSL, plug-ins for an SVG graphic editor (plus source window), etc.

This is all speculation on my part, but...
Your email address begins with "anonymous". Some SPAM software may not mail to "anonymous", or remove the "anonymous" from the address.
Your email address ends with several digits. It's possible that some SPAM software drops the digits and mails to "anonymous@..." instead.
Put the above two together, and your email addres becomes null.
On a slightly different note, I've read somewhere that most SPAM software doesn't send mail to "abuse@...", so if you have your own domain, use "abuse@..." as your email address, and you will rarely get SPAM.
I once posted to a newsgroup using the address "xyz-dont-spam@...", and started receiving SPAM at "xyz-dont-@...", so some SPAM software does play with email addresses.

My newest machine is a P2/300 with a Permedia 2 3D graphics card and 128 MB of RAM. I bought it around 1997. The only hardware upgrades have been additional disk (now about 60 GB) and disc (CD-RW) drives, and I replaced the original monitor only last month. I use it 10-20 hours/day, and rarely turn it off.
My other machine, which I still use occasionally, is a P1/75 with 16 MB of RAM and no 3D accelerator card at all. It's from around the late 1980s or early 1990s.
I also have a Commodore Amiga 2000 that I use very infrequently. Its only upgrade is a 40 MB (that's MB) hard drive. I bought that around 1985.
If templates & the STL are such gigantic points of productivity in C++, why were they not part of the original C++ specification?
Maybe because they weren't invented yet? Maybe because the original C++ compilers compiled to C (cfront, ugh), and so templates were very inefficient at the time?
C++ has evolved over the years. New things get added. Python only recently got generators. LISP has been around since the 1950's, but it didn't get CLOS until sometime in the 1980's.
Just because something isn't in the original language doesn't mean it's not useful. Many times various extensions to languages/standards are tried. Those that are successful may make it into subsequent definitions of a language/standard; those that aren't tend not to.
Re: Soft vs Hard G

I was under the impression that the "g" used in words like "gimp" and "give" (and "go" and "gate") is called a *hard* g, and "gin" and "gip" use what's called a *soft* g.
You are correct (except that it's spelled "gyp" here in the USA (derogatorily derived from "gypsy")). A hard G is like the G in "garage", whereas a soft G is like the G in "garage".
Hand tools were first developed for the Apollo space missions.
That's just not true. My grandfather made things out of wood, and he sometimes held pieces of wood together using little tapered cylinders of iron or steel called "nails" and "screws". It was very difficult to cause these cylinders to enter the wood simply by pressing on them, so he used hand tools called "hammers" and "screw drivers". All of this occured long before Apollo.
Yeah, I followed the link. No, I didn't get it until I read the solution. Even now, I recognize the shape only vaguely. If I looked at it a month or so down the road, after I forgot about it, I probably wouldn't be able to recognize it. I still think that rectangular boxes would be esier to decipher.
Why should it increase its angular velocity. At lower orbits (ie shuttle) you have to have higher angular velocity to maintain orbit.
OK, don't look at the orbit with respect to the ground. Assume that the Earth doesn't rotate at all, and you have a cable that is hanging from 36,000 miles, but not touching the ground.
Now, an object in higher orbit will orbit the planet more slowly than one in a lower orbit. (For example, the space shuttle, in LEO, orbits about once every 90 minutes.) What about an object in a severely elliptical orbit? Its orbital period will be somewhere in between.
What causes an orbit? The gravitational attraction of the planet pulls an object down. The object is traveling forward. The deflection of the forward velocity makes its path circular.
Take a rocket sitting in high Earth orbit. Fire the rocket directly toward the Earth. (This will be equivalent to the lower parts of the cable pulling on the upper parts.) The rocket will travel toward the Earth, but it still has its forward velocity. It will thus be deflected into a lower Earth orbit. An object in a lower orbit travels faster than an object in a higher orbit, so the new (now elliptical) orbital period must be smaller (i.e., faster).
But, let's assume that this doesn't happen. Let's assume that the cable falls straight down. When it hits the lower atmosphere, it will start to flutter. As it does this, it will be traveling at great velocity. Friction with the lower atmosphere will heat it up, and it will burn up.
I guess the point is, now matter how it falls, most of the cable will be traveling at such a high velocity when it hits the atmosphere that it will burn up.
One final thing: Most pictures of the space elevator show the cable hanging straight down from its upper base. I don't see how this is possible. I think that the cable will hang down in an arc, and the base of the elevator will not be directly below its top. But I don't know much about orbital mechanics, so I could be wrong.
This thing is in GeoSynch orbit. It has 0 lateral motion relative to surface and hence 0 motion relative to air that causes friction) it would not burn-up, Right?
Wrong. While it has 0 lateral motion WRT the surface, it is still in orbit. As sections of the cable drop lower, their orbital velocity will increase WRT the ground, and the cable will try to "wrap" itself around the planet. By the time that most of the cable hits thicker atmosphere, it will be going at a pretty good clip, and will burn up (even the light, "fluttery" ribbon sections).
Here is an experiment that you can try in the safety of your own home to verify this:
Evacuate all of the air from a room (to prevent stray air currents from skewing the results).
Drop a ball from a height of, say, 6-10 ft or so.
Note where the ball landed WRT its release point.
You will see that the ball landed several microns East of its release point (and a few microns toward the equator, as well). A few microns might not sound like much, but multiplied out to 36,000 miles, that's a lot of microns.
