From what I can tell, very little is actually *described* in the

Yeah, you can do all kinds of really funky stuff with systems of
differential equations, and the graphics hardware is pretty much
designed for this type of number crunching.

I can't imagine what the possible security risk could be...

Oh, yeah, I get how a graphics card works. What I can't figure out is
how some of the effects that Milkdrop generates are mathematically
possible. Figuring out the math is the hard part; actually making the
hardware do it is usually quite simple.

It's enough to get a person going with preset authoring.

Actually, I was describing what /Milkdrop/ does with a graphics card.
All VJ'ing apps are pretty similar, I think.

OK, you're going to have give me an example... give it over! Pick a
preset from Milkdrop's standard distribution that epitomizes this
nearly-impossible effect, and I'll tell you how I *think* it's done.
Maybe other, more knowledgeable people will join in as well, and we can
get to the bottom of this thing ;)

Distributing signed code via MS technologies requires you to get your
signature from MS, at least in many cases. Bascially, you buy a normal web
cert from a CA that MS trusts (any of several of the big ones), and then
sign an empty ActiveX file with it, and send that to MS along with your
public key, and MS signs the public key and sends it back. You can't just
use a self-signed cert, at least for most of the stuff I've seen that deal
with certs.

It would seem that Sun doesn't require the purchase a web certification,
which is good for me since I don't plan on selling anything.
Hey, you seem knowledgeable about these things. I'm looking into using a
file-hosting service to free up more space for my (future) site. Do you
know of a good service that will allow me to store Java applets and use
them directly in my pages? My ISP gives me a measly 5MB site space (you
would think they'd be more generous, since I'm paying $20/mo for 24Kbps
dialup), so to post more content I must rely on file-hosting services.
I'm confident that I can use Photobucket for my images, but Java applets
might be a little more difficult to get working.
I think that if I can get away with using my 5MBs for only HTML/CSS, I
can stop worrying about running out of (my preciousss) space.

Yep. It also brings up that whole responsibility thing. Why do they make you
sign it if they're not going to do even a nominal check on the signature, I
wonder? :-)

Last I looked (and that was a while ago), Java applets had to be served from
the same host the HTML that embeds them come from.
Myself, I use amazon.com's s3 service for sloshing web files around. You can
set the content type as you need it there, make stuff public or private,
etc, and it's super cheap. (I think I wind up payin <$2/month to store all
the random crap up there I have.) There's no execution, you can't easily
put a home page on it (since http://..../ doesn't default to redirecting to
http://..../index.html or anything like that), and as I said the applet
probably has to come from the same place as the html.
That said, you could put an HTML page up on your expensive host that's
simple meta-refresh redirect to an HTML page on amazon that references the
applet.

I don't really do anything web-sophisticated on my own dime any more, so I'm
kind of out of date on the options.

If you don't mind administrating your own site entirely, and having it
on a virtual machine, some people are using this:
http://www.tektonic.net/
to host their own applications even, like OpenSim, and the like, since
you can install more or less what ever you want into it.
Found it nosing around to see what sort of places out their might host a
sim, to make building easier, without paying someone else anywhere from
$40-$250 a month for it instead.

Yeah, Amazon has a lot more services than their S3 storage server, but
there's a lot of competition that is cheaper than Amazon's rates on compute
time. Amazon has a bunch of different storage and CDN and hosting and
database solutions too, but if you're just looking for plain old cycles, you
can get it cheaper than amazon these days. Their raw storage, however, is
super cheap. Like, $0.15/gig/month or some such.

I have yet to find a virtual server offering that I could even plausibly
afford. The cheapest I've seen is, like, £15/month, which is way more
than I want to pay. Any suggestions?

Not offhand. You could bid spot prices on Amazon servers for whatever pri
ce
you want to pay and see if you get any. :-) But there's a lot out there.
It's possible there's a virtual server farm that cheap.
