[gentoo-user] a star-map wallpaper?

[张 韡武]

Hello. Sorry for my English if there is a more correct way of saying "Star
map". By Star Map I mean something that shows the position of starts, as
well as brightness. The more like photo, the better.

Star moves in the sky all the time:
1) the star map in 20:00 is different from 21:00
2) the star map in today 20:00 is different from what it was yesterday 20:00
3) the star map in one city is different from in another city at the same
time

I am looking for an application dynamically change the backgroup of my gnome
desktop, showing the correct starmap of the very city I am in, of the very
day and correct moment. That might require the desktop image being replaced
once 15 miniutes, that doesn't matter, that's what I need.

Just U am too stupid to find it on the google, have anyone heard of such
application before?

The cloeset I could find is "nightfall"
http://www.hs.uni-hamburg.de/DE/Ins/Per/Wichmann/Nightfall.html
But still, that is too complicated and very accurite, what I really want is
some fancy desktop decoration, and it's so much of a waste not having such a
tool in an office that can see part of the sky.

KStars (http://edu.kde.org/kstars/) has a command line mode for image
generation.
It should not be difficult to script that to generate an image, then
set it as the background.

You can do the scripting using DCOP to change the background.
Here's an intro:

I recall of a wall paper/screen saver, which would fetch satellite images of
the globe and update your desktop (almost) in real time.

I think it used this link.

http://meteosat.e-technik.uni-ulm.de/meteosat/index-latest.html

The same script with a satellite that captures and feeds images away from
Earth as opposed towards it should come close enough to what you're after.
Not sure if this helps.  If it does, unlike a simulator like Kstars it will
of course show all the latest supernova and eclipses of planets, more or
less as they occur in Earth time.

I always hoped for Celestia to have this functionality. It would be
wonderful to follow, let's say, Cassini from my desktop :)

I think the keyword to google at is "planetarium". I woulsd be
interested to hear of your final solution, even if I'm too lazy to do it
myself.

The word you are looking for is 'chart', as in 'star chart'. Google
for 'star chart wallpaper linux' or some phrase like that.

I don't know if any program of your specification is available, but
for KDE at least you can run a graphic program in the root window and
use that as a desktop image, thought I don't know about gnome. 
 
Try looking at some of the following to see if you can at least use it
to meet your needs:
  xephem:  http://www.clearskyinstitute.com/xephem/
  pp3: http://pp3.sourceforge.net/
  kstars (yes, I know you are running gnome):
       http://edu.kde.org/kstars/
  Mag 7 star charts: http://www.cloudynights.com/item.php?item_id=1052

If you don't care too much about accuracy, some elementary mathematics
plus the Mag 7 star charts, a cron job, and an image viewer with
ability to set the background image (like qiv or xli) should allow you
to dynamically switch the background image to the roughly correct star
chart.
