An animal after my own heart

Is this bird the coolest in existence? Maybe, maybe.

Our host calls it an interior designer, but I was more torn between a collection development and a cataloging librarian. I guess more collection development, because I didn’t see any surrogates for the items. Maybe it works on an OPAC in its spare time?

the process of learning

When I take a class, I take notes in that class. I write down interesting things; I try to replicate the structure of the lecture; I add my own thoughts when they come up (in boldface, since I type). I rarely ever look over my notes again. They simply allow me to commit to memory the content of a lecture by the act of typing them down.

I’ve been trying to learn scheme, and more importantly larger program design principles. I have not taken any notes. Why? Because there is no “big person” some 10-30 feet in front of me telling me all about these things. That situation does not sufficiently change my need to write down what I learn so I remember it. Duh.

I’m taking notes now. Here.

Part 4: Conditional Expressions and Functions

boolean values = truth values = true or false responses to conditions
think of x < y , x > y , x = y . these can be combined into compound claims

Scheme has:
= , < , > , <= , >=

(< 4 5)
[not a number!]

(and (= 5 5) (<5 6))
(and true true)
[for and, all conditions must be true for the whole expression to be evaluated as true. or and not follow like you’d think]

I’m getting used to (define). Yay!

Intervals (between 6 and 7) and combinations/unions of intervals (between 6 and 7 or over 10)

I need to remember that contracts and purpose statements clean up my thinking. Very useful to write.

not reverses the > and < signs (when writing on a number line)

(more to follow)


I’m not well trained in statistical methods for social research. But I can recognize a poorly designed survey instrument, and I can definitely recognize horridly (under)analyzed data. These things make me angry. Well, they don’t make me angry on their own; I get angry when work of this caliber gets published.

More on this later.

Only rotated sometimes?

While allowing myself to be distracted from writing an altogether too lengthy set of requirements for what’s looking to be a PIM system, I saw on Pandora that the music I was listening to had the artists’ names rotated. I selected the Classical genre station (Chamber, Baroque to be precise), and all the artists look like Bach, Johann Sebastian and Corelli, Archangelo. But on other stations I have, the names aren’t rotated. At first I thought maybe I’m thinking of bands, whose names shouldn’t be rotated. (I mean, Punk, Daft? No.) But I looked and saw that specific people’s names aren’t rotated either. (Bob Dylan, for example.)

Is this a function of the genre stations in general? Is it because of the specific genre I’m listening to now? Is this more about how the metadata is captured? (I think this has at least a healthy chunk to do with it.) Should I get back to my paper?

I know the answer to one of these questions!

Also, damn Trent for introducing Pandora into my cognitive life. I get so OCD-fixated on it!
