I’m hooked on the APOD

I’m hooked on the APOD site now. It’s a real wonder. First I went to gawk at the pictures, then I discovered that the prose and links at the bottom are also very good. For instance, I found this cool Soviet propaganda booklet about Yuri Gagarin. Ever wonder why stars in astronomical photographs look like they have four spikes sticking out of them? Find out why: APOD: 2001 April 15 – Diffraction Spikes: When Stars Look Like Crosses. The spikes article led me to the Nobel Prize site, which has some tasty articles about physics: Nobel e-Museum.

Google is doing newsgroups now,

Google is doing newsgroups now, and with Deja.com’s database behind them, they’re going to do a damn good job of it. For instance, here’s comp.soft-sys.matlab, the newsgroup devoted to the product I work on, MATLAB.

It’s exactly the kind of mind-numbing, brain-sapping, brute force mud-wrestling with gigabytes of unruly data challenge that we enjoy.” Amen.

I was reading something (can’t

I was reading something (can’t remember where) about why people write open-source code. It used the word “reputationism” (as opposed to capitalism) as the motivating force. I think there’s something to that. The author mentioned Advogato’s trust metric as an example of how trust and reputation can be automatically tracked in large communities. If this kind of thing works, it really does make new social structures and kinds of work possible. This is related to Francis Fukuyama’s concept of social capital.
