I tried this one (the .armel.db) but got the message 'incompatible application'.
Is there a working version of this app ?

skatebiker:

I don't know what 'this one' is that you are referring to. On my own N800, when I query for 'gpsbt' I get:

ii libgpsbt 0.2-42 Library for finding paired GPS BT device and
ii python2.5-gpsbt 0.1-18osso2 Python bindings for osso-gpsd lib.

Is this the one that you are attempting to install? Do you already have python2.5 on your tablet? Which version of the OS are you trying to run?

Super....
did that and got

Traceback (most recent call last):
File "/usr/lib/mephemeris/mephemeris.py", line 43, in <module>
import xml.dom.minidom


Found it by searching...
installed Python2.5-xml and I got Mephemeris to launch!

Thanks!

Now I have to read the docs..great start. I am looking forward to using this! Thanks so much for your effort!

Glad to hear that you got Mephemeris off the ground!

The problem with the missing 'minidom' is strange to me -- I do not recall such a problem myself -- I think when I installed python2.5, all that 'extra' stuff (like minidom)was brought in for me automatically. In any case, if anyone else runs into this, your posting will help them.

Maybe you can even help the others (like 'skatebiker' above), if you ran into the same problem as he did with 'python2.5-gpsbt' i.e. where did you get it from?

Hey...
It took a while to find it and I don't recall which repository it was in and my battery just died. I will try to figure out which repo it was and post tomorrow.

The app looks great!
Wish it was a bit faster but certainly and awesome effort!

- It was this one which I tried to install
-rw-r--r-- 1 user root 38746 Nov 3 19:43 python2.5-gpsbt_0.1-18osso2_armel.deb
- I have python (as I have pyDesktop running successfully) but don't know what version and how to find out

skatebiker:

Well, your question is not so much about 'mephemeris' as it is a question about the packages you have installed, and the respositories you have configured (or not) -- so you may want to post your question in a new thread (or perhaps there is a good answer out there already).

However, out of curiosity, do you know if you also have 'python2.5-runtime' installed? When I run the following command on my tablet (in a terminal session, of course):

dpkg -l|grep python2.5

...I get the following output, which shows me all the 'pieces' of python2.5 that I have installed:

ii python2.5 2.5.2-1osso3 An interactive high-level object-oriented la
ii python2.5-bluez 0.9.1-1osso2 Python wrappers around BlueZ

ii python2.5-xml 0.8.4-1osso9 XML tools for Python

Yea, I wish it was faster as well But to be honest with you, I am impressed about two things:

1) That such a highly number-crunching application like this can be written in 'python' (instead of 'C') and perform reasonably

2) That python can calculate the positions of hundreds/thousands of astronomical objects on our tablets in just a few seconds

The 'optimizations' that I had already done to improve performance (where I could) included:

- sorting (and plotting) the data in 'magnitude' order, to eliminate calculations for objects that the user didn't want to see anyways

- store planet orbit calculations in an array, rather than re-calculate them each time the person wanted to zoom in/out (this dramatically sped up screen refreshes)

Yes, if I was really the 'expert' programmer that I have always dreamed of being, Mephemeris would be a LOT faster and cooler, but I decided that people might want a feeble app rather than none at all

Where do I get 'python2.5-runtime' ?

skatebiker:

Again, I am not the best person to tell you where to download stuff from, or what repositories to set up. All I can do is tell you what *I* have set up on my own N800. Apparently, the repositories that I have configured in application manager are:

deb http://repository.maemo.org/extras/ chinook free non-free
deb http://packages.collabora.co.uk/maemo chinook haze salut idle
deb http://www.fbreader.org/maemo chinook user
deb http://repository.maemo.org/ chinook free non-free
deb http://maemo-hackers.org/apt chinook main
deb http://elkins.org/packages chinook main
deb http://catalogue.tableteer.nokia.com/certified/ diablo user
deb http://catalogue.tableteer.nokia.com/non-certified/ diablo user
deb http://catalogue.tableteer.nokia.com/updates/diablo-1/ ./

Did you run the command in the previous email on your own tablet to see what python2.5 libraries you have installed? How did it compare to mine? Did you have the 'runtime' one installed? What repositories do you have configured?

Although I occasionally use 'application manager' to install stuff, more often than not I use 'apt get' (in a terminal) instead.
