Just Moon

It's still very experimental, but it's getting to the point where it's actually useful. It's a bit slow to draw objects, so I'll probably work on speeding it up a bit. Note: you can tap and hold (on the Zaurus) or doubleclick (on a workstation) to get a dialog with a little more information (not much yet). It knows the roughly 2000 lunar features from the official USGS list; it has two zoom levels (full and half) and can mirror left/right.

Platforms and downloading

To run any of the binaries except the Zaurus package (which is self contained), you'll need the data files and images from the source tarball (justmoon-0.3.3.tar.gz, even if you don't build the binary. Unpack the tarball with
tar xzvf justmoon-0.3.3.tar.gz
then run make installdata as root to install them.
(See the file named INSTALL for more information.)

I'll make Just Moon linux binary packages (RPM and deb) eventually -- watch this space (or pester me if you want one sooner).

Download a Zaurus/Opie package here (somewhat older version): qmoon_0.2_arm.ipk.

The gtk version also runs on Mac OS X, under XFree86. Here's a mac binary, compiled on OS X 10.2.2. You'll need XFree86, gtk+, and gdk-pixbuf, available as fink packages: fink install gdk-pixbuf will get all of it, but it may take quite a while if you don't already have the gnome libraries.

In theory, both the gtk and qt versions should run on Windows, but no one with Windows and a compiler has expressed interest in trying.

Source Change Log (and tarballs)

• 8/20/2003: 0.3.3 Use /usr/local as the root instead of /opt/qtopia. Minor code cleanup.
• 11/15/2002: 0.3.2 Fix a crash in qmoon (image wasn't being initialized properly) and rename the directory to justmoon-version.
• 10/15/2002: 0.3.1 Introduce gmoon, the gtk front end.
• 10/1/2002: 0.3 Factor front-end and back-end code, and move all the qt code off into a subdirectory, to facilitate (1) smarter makefiles (easier to switch between qt build modes) and (2) alternate front ends (gtk, mac, whatever).
• 9/25/2002: 0.2.1 Fixed icon handling on the Zaurus; made separate .pro files for tmake/qpe vs. qmake.
• 9/22/2002: 0.2 Fix (I think!) the mysterious disappearing image problem. Improve image rotations, and tune offsets for zoomed images.
• 9/8/2002: 0.1.9 Add zoom feature.
• 9/7/2002: 0.1.8 Shift labels so they're not drawn offscreen; draw mountains and rilles as "X" if we don't know their orientation.
• 9/6/2002: 0.1.7 Add larger-size image, for running on a workstation. Code cleanup; have objects draw themselves.
• 9/5/2002: 0.1.6, 0.1.5, 0.1.4, 0.1.2 Add more data types (Rilles, Mountains, etc.) and ways of drawing.

I also have some Astronomy Java applets (with Zaurus packages), and some PalmOS astronomy software.
