I'm starting an experiment today. The program is Everyman: 3 20 min naps at midday, the afternoon and the evening with core sleep gradually decreasing, hopefully to a small number of hours. I have early morning lectures and function well at night, so short of being nocturnal decreasing my core sleep looks the best way to be efficient. Will keep this tread updated with results.

Optimizing Sleep
Update. I've discovered I dont function nearly so well at night as I had anticipated. I was running with core sleep 4-8, after shifting this to 2-6 I can see an improvement.
Also notable features: I can shift the naps around a fair amount, but too much core sleep, or hitting the snooze button after waking from core sleep throws me off for a long time after. The amount of sleep in each session doesn't seem as important in how I feel afterwards as how I wake up. Waking up in the middle of deep sleep going blurg and snoozing for 10 mins is followed by feeling awful. Being in light enough sleep that my phone screen turning back on before the alarm goes off is enough to wake me and then getting straight out of bed is followed by feeling really energetic.
It's incredible how much sleep I'm able to get in the naps. Sometimes schedules mean I can only really afford 10/15 mins, and I feel myself waking up from real sleep after this.

I take it the four posts are a mistake?
Sorry, trying to be cunning and failing.

Sorry for confusion. Mistyped the date. The meeting is on Sunday not Saturday.

Dutch Books and Decision Theory: An Introduction to a Long Conversation
The question that needs answering isn't "What bets do I take?" but "What is the justification for Bayesian epistemology?".

I'd always thought "What bets do I take" was the justification for Bayesian epistemology. Every policy decision (every decision of any kind) is a statement of the form "I'm prepared to accept these costs to receive these outcomes given these events", this is a bet. If Bayesian epistemology lets you win bets then that's all the justification it could ever need.
Are you tracking your sleep with a Zeo or at least a cellphone accelerometer?
How are you benchmarking your mental state? Memory may take a serious hit, are you using something like Anki which records statistics on forgetting/memory performance? (Working memory and executive function are also issues, so I would suggest dual n-back.)
At the moment I'm tracking sleep with a pen and paper, just started with an Android app. Zeo was totally unknown to me. Thankyou, will investigate this.
My plan is to go by the metric that matters to me, university work. I get enough data there to notice something going wrong. Not the same detail as proper Anki-style benchmarking, however there is an extra variable in my case (resulting in high variance on the day/week scale), that would spoil such results.

There were certainly enough people interested to make this regular. To get involved if you weren't here today join the google group at http://groups.google.com/group/cambridgelesswrong

Wow I didn't realize this was happening! I'm super busy tomorrow but will try to come for at least some of it. When was the last meetup?

I'll be there. Also, "Meet at the Great Gate" is a bit uninformative to people who aren't from Cambridge. Meet at the gate on St. John's Street that is pretty much opposite the bookshop "Heffers".

My impression was that the problem with Babbage was largely that he was a terrible manager (like Einstein and many other scientists) and thus failed to deliver what he promised even though it was a reasonable proposition given the tech of the day (as Myhrvold demonstrated).
He was also horrific at politics. Nobody with half a political brain writes this: http://books.google.co.uk/books/reader?id=3bgPAAAAMAAJ&printsec=frontcover&output=reader
