I see your 1970s and raise you the 1950s. I've known a professor or two with boxes of Hollerith cards containing their graduate-school era FORTRAN code.

Also, you wouldn't even have to type anything in, assuming you could find a reader or could afford a student to scan them in and write an imaging code to interpret it. Because, hey, what's more useful than Version 1.0 of the code on which you made your bones?

Comment Get Off My Lawn, Astro Division (Score 5, Interesting) 498

When I was in graduate school one of my tasks was to read old astronomical CCD images that were written on magnetic tape (and there were a lot of them, since my advisor had been testing CCDs for the Hubble). So for a couple of months I sat in a small workroom with the department's only working Kennedy drive reading tapes.

Because of age and prior use, many of the tapes were shedding oxide, making the drive rock back and forth over many segments in an attempt to retrieve the blocks thereon. After every few tapes I had to wipe the oxide from the read heads. Then, just to make the process a little more tedious, the data itself had to be byte-swapped. As a reward for all of that, I found one image to use in my dissertation.

The data was written to CD-ROM in the late 90s, so I expect there's someone right now trying to figure out how to read the data off of the decade-old, decaying archive. If they're lucky, they'll find the backup DATs in the filing cabinet and the last working drive in the department.

Have you ever seen a conservative on Olbermann? Not much balance there.

Sure — Dave Weigel. Unless you meant "conservative"-as-in-partisan-Republican, in which case, not regularly.

Have you ever watched Maddow? Nothing but shill.

She used to have Pat Buchanan on there, and and had several interesting discussions with him. Then he went completely batshit crazy (even for him) during the '08 elections and one of them decided they were no longer worth it.

Wrong. The canonical number used in galaxy modelling is 20-to-1. That number is inferred from the rotation curves of spiral galaxies, not ellipticals, but that's the ballpark. And then there' this:

"But there’s still plenty of dark matter, too, according to van Dokkum. In fact, the new stars probably won’t change the accounting of dark matter very much."

But hey, look at me being lazy and just quoting the article you cited.
