Breakfast of Champions

I hear the movie is terrible, and I can't imagine how it could not be.

Though it was sad to see Chinaski in a cage, it's always nice to visit him.
Born on a Blue Day

I've heard there is a BBC documentary that shows more detail of his mathematical methods -- I have tried to find it online, but haven't had any luck.
One thing that this book spurred me to do -- get a better handle on the calendar. I had a friend when I was a boy who had a touch of savant syndrome, and could easily tell the day of the week for any date. I would ask him how, and he would just say, "I don't know -- I just see a picture of it in my mind." Well, I figured this would be a useful skill, and I came up with a method I've been using. No, it doesn't go back in time very well, but if you want to know the day of the week for any date in the current year (or even next year) it is quite serviceable.
It works this way:
1) Memorize the "zero day" for this year. That is, the day before the first day of this year. So, January 1, 2009 was a Thursday, so the "zero day" for 2009 is a Wednesday.
2) Memorize the "offset table" of days for each month of the year. This is a simple list of numbers: (0, 3, 3, -1, 1, -3, -1, 2, -2, 0, 3, -2) that maps to the months of the year. Some are easy to remember -- "October" is 0, for instance. But really, memorizing that list of 12 numbers isn't very hard.
3) So, if you want to know what day a given date is on, simply divide 7 into the day, add the remainder to the offset, and add that to the "zero day", and you have your date.
For example: Christmas, 2009 is the 25th. 25 / 7 = 3r4. The remainder is 4. Add 4 to December's offset (-2), giving you 2. Add 2 to Wednesday (the zero day), and you get Friday. So, Christmas 2009 is on a Friday. With some practice, I find this pretty easy to do in my head, and I can answer questions about what day of the week a date is on in about 5 seconds. Unfortunately, when you tell people this, they immediately want to test you to see if you know what day of the week they were born on. Somehow, people have the idea that knowing distant days of the week is more useful than knowing upcoming ones. I mean, I can figure out the distant ones -- each year, the zero day creeps forward by one, except in leap years where it creeps forward by two (thus the "leap"), and this creates kind of regular cycles -- but it takes me almost a minute to work out a distant one. I'm sure there are better methods that my crude one for that. But I like my simple method for upcoming months!
Synecdoche, New York

More and more I wonder about art and creativity. I used to think that creating a thing for a specific audience was the best and wisest method -- but as I grow older I see more and more that creating a thing for an audience can spoil a thing, and riddle it with compromises, that ultimately make the audience turn away from it. More and more, it becomes clear that the best path is to let a thing you create be true to itself, and to focus on nothing but that. Now, sometimes, part of that involves visualization of the audience interacting with it, or observation of the audience interacting with it -- but that *only* helps in the weird context of helping the created thing be true to itself. This is very hard for me to talk about -- but more and more I think it is the only important part of any creativity. I hope I can find ways to talk about this more clearly.
PS -- Synecdoche (sin-ek-duck-ee) is a greek word meaning "shared understanding", more or less.
Fresh Air: Laughs

This strange experience aside, the interviews are excellent, and give great insight to the variety of methods of comedic process.
