Thoughts on data-saving
I wouldn't say I'm against IDE drives, just that whatever system we choose makes sense in terms of scalability and reliability. The problem with IDE isn't the speed or capacity, but rather the limit on number of devices -- namely 4. The system drive takes one spot, leaving 3. I'm not sure the case a...

Argh... goofed my math.

That should be better.
Thanks,
Dave

predicting image timestamps
The schedule is predictable, and the filenames used to match that. Images are taken on a sidereal-based schedule. (every 3:56 from midnight). However, it looks like the filenames are off by a second or two for lots of images. Ideally, the algorithm you'd use is: stamp = seconds since 00:00:00 GMT de...

Re: Yes
Well, the world map is indeed highly non-intuitive, but it makes one think about it, eventually realizing that NSL "looks" from earth up. I'm not quite sure about this, but the reversed map might make visitors try to figure out what NSL actually is. Perhaps my argument is rather weak, but...
