Invitation - Lucky Number Slevin

I think this is my first free saturday since nearly christmas :) I would quite like to see Lucky Number Slevin. It has Bruce Willis, Lucy Liu, and Morgan Freeman, is generally reviewed as rather violent but very good, and a supposedly intricate plot compared to the sting.

The only showing on sat is 9.25 at cineworld. I'd probably like to go for pizza first. Does anyone else want to come along?

Alternatively, Inside Man had the same reviews and is on in the early evening at Cineworld or Vue.

Email as account id

Generally I like email as identifying my account on a website. I have a couple of email addresses, but can manage to identify one primary one, and it (a) aknowledges that I want to log in with the minimum of fuss (b) avoids having to choose a name that obeys their restrictions (c) yet is easily unique (d) and you have to enter your email *anyway*.

Though I embarassingly discovered a dark side to this approach: I managed to sign up to two amazon accounts with the same email, and it looked like my account history had vanished. I was quite cross with them, until a nice rep emailed and explained what had gone wrong. Then I felt really stupid, though kind of peeved that it had happened.

But I'm not sure what the right approach *is*.

(a) Restrict to one account per email. This is probably simplest, but annoying for places where I would like to keep things separate. I might want a CTS account and my account, but not want to set up a separate email address for the other.

(b) Log in to whichever account's password is given. This is what happened here, and is the quickest to use, but as I found, rather unhelpful. I click on a link saying "leave seller feedback" and it doesn't go anywhere, because I'm logged in to the wrong one.

(c) Allow two accounts, where it has a little drop down list on which you can choose a description you entered (but are not required to retype). This is probably best, but gets as complex as the original sysetm to implement.

What's best?

ETA: For that matter, could we have a unified email authentication scheme? My email account could be integrated with a little list of sites that have requested me to confirm that I signed up to them, initially via a standard email layout, later via some less profligate protocol, and I could hit 'ok' to them all quickly. And my browser could have a 'confirm' button plugin that did it automatically after I filled in the form :)

Epistemology #0

Recently I saw discussions on AI, and the possibilities of representing its knowledge by assinging % confidences (subjective probabilities) to statements, and the problems where a belief in one part of the brain didn't match that in another. I've read a lot around the topic, and Hempel's paradox, and Bayesian reasoning, and upper-and-lower probabilities, and may follow up with some contentful posts, but I experienced that cognitive dissonance today, and thought I'd record it.

Me: Ooh, there's another Cat wizard book by Diane Duane. It's being partially published online, it's really interesting to see professional authors continuing to investigate that. And she says "beta readers".
Me: Hold on, *have* I read the first one?
Me: I ordered it from amazon marketplace, I was excited about that.
Me: The books arrived.
Me: I've read all of them but [other name] and [other other name].
Me: So why don't I remember it?
Me: Checks autoconfirm email. Paid for.
Me: Doh! Goes to write previous post. Emails amazon. Checks bank statement and sees refund.
Me: Hmmm. Apparently that chain of 95% certainties was weaker than all the links, and something fell into the 1-0.95^n gap. "The" books arrived, I didn't stop to think if that was "every" book...
