You still can type x^2 right-arrow y^2 right-arrow z^2 right-arrow if
you like.

I understand. The fingers are on their own at this point, there's not
talking to them. But they should be happy, ^ still works.

My audience is compelled to do problems like 3a^2b^2+5a^2b^2=8a^2b^2
twenty at a time. I do not think they would be my audience very long
without a smart editor.

Thx. Now let me see if I can get it working again, tried to edit it in
emacs on the AWS Ubuntu machine. Or is it Fedora?

At a complete tangent - how hard is it to get AWS EC2 (which is what I
assume you're using) to work? If there is persistent state needed but
you don't want the instanc(es) all the time, is that easy?

I'm asking out of pure laziness, I haven't tried this at all (I use S3
a lot, but other than vaguely looking at manuals I've not looked at EC2
at all)

You'll need to click on about a dozen buttons.

I thought you said you used S3 a lot. S3? State? Hello?

Yeah, you can shut instances down and bring them up and clone them. I'd
go with s3 for shared state, of course.

Do you have a mouse? Any way to access the interwebby? I might be
exaggerating, you might need a keyboard, too.

Getting a nice Gnome desktop eluded me, but it seems possible. I just
need to run a web server, so I can get buy with Stallman's Great
Contribution: ascii interfaces.

What I meant really was "bootable disk image with whatever
configuration is needed" - if the instances can boot from S3 that's
ideal. Obviously one could write stuff to take a fresh unconfigured
instance and put on whatever things you need, and you'd do that if you
wanted lots of them, but for a small number (one, really) it's often
easier just to have a sacred boot image.

Oh. Yes. They have images, snapshots of images, and volumes. Fair
warning: you'll need a two-button mouse because options like "Launch
more instances like this" are only available via the context menu.

It's way cool.
