Jeff Erickson's Publications

It is true that systems that people use today would be much better if their builders had read the papers published by academicians in the 1960s and 70s. This is a little unfair to the practitioners, though, because nobody has ever shown that academic computer science journal articles have any effect on either practical computer programs or even on academic computer science research.

- Philip Greenspun, "We Have Chosen Shame and Will Get War."

I do remember one thing.
It took hours and hours,
But by the time I was done with it,
I was so involved,
I didn't know what to think.
I carried it around with me for days and days,
Playing little games,
Like not looking at it for a whole day,
And then looking at it,
To see if I still liked it.
I did!

- King Crimson, "Indiscipline", Discipline

I wish I had learned about decision trees in high school. Decision trees taught me to think. Decision trees are useful. Geometry is not.
