Re: ANNOUNCE: Mephemeris - Astronomy Program
tz1:
You didn't make it clear what your goals were for your own astronomy program. Are you working on it? When do you intend to release something for us to try out? I need some 'role models' out there so that I can learn from what other people have done re: astronomy programs, especially for our tablets. :) I wish the author the 'Stars' port for Maemo would pick it up again, since I like the slick 'rotating sphere' look of it. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Hello again, darethehair. Well, once again this is a truly amazing effort. I have just scratched the surface of the update, but I like many of the new GUI options (show hide columns,etc), the amazing amount of downloadable web info (including the satellite elements info), etc. Now I understand that TZ1 has some good points and that the overall GUI may be a little funky, but it does work well! I am not quite to the point of either criticizing or offering good suggestions yet. But you get an A+ for effort and usefulness.
I would like to hear a bit more about your development environment and methods (when you have time) and how you packaged it into an armel debian package. Also, since this is Python, how and where could I get information that would allow Mepheremis to run under Python on OSX on an intel macintosh system. That is all for now. I will check it out thoroughly when I have time and ask more questions and offer suggestions at that time. Thanks again for a great piece of work! P.S. - Can you (and will the maemo powers allow you) to put this someplace where it will trigger the update notification icon under N800 OS2008 diablo? |
Re: ANNOUNCE: Mephemeris - Astronomy Program
The goals were merely a compass like viewer. Eventually to Aho's planetarium (link in the earlier post). I.e. if the dot representing the sun is at 135 degrees, I should be able to find true north by aligning the dot for the sun so it points that way. If I point north (or use GPS heading to turn) I can find the direction for the planet or stars, and the elevation.

I know absolutely nothing about Mac OSX, other than it is based on BSD (?) and is therefore theoretically more capable of easily running unix-ish stuff than WinXP is (?). Strangely, although it appears that PyGTK is 'standard' for Linux distributions, and nicely packaged for WinXP, that it is still 'in development' for OSX. Here are a few Google hits that I found: http://developer.imendio.com/projects/gtk-macosx http://wiki.laptop.org/go/Sugar_on_MacOS_X http://py25-gtk.darwinports.com/ http://www.gossamer-threads.com/list...7647?page=last I don't see a 'consistent' message here, but I suggest that you inquire within the Python and/or OSX community for more info. As for how I packaged this, well, like the README says, PyPackager comes to the rescue when I need to do that. As for setting up the context to actually use PyPackager, well, I guess that can be a different thread :) I am not sure about the 'update notification' thing, but I doubt that it would do much good for Mephemeris, since I don't see myself doing a lot more development and releases for a while :) |

Re: ANNOUNCE: Mephemeris - Astronomy Program
Thank you darethehair for the PyGTK and Pyackager info (mea culpa, I read all of the Mephemeris usage info, but not ALL of your history info where you mentioned PyPackager, etc.).
I do have Python 2.5 and Python 2.6 running on my Intel Mac-mini under OSX. So I guess I will have to check out PyGTK, etc. (Of course now I am just starting some consulting work so I will be too busy for a while to do it!). Also, thanks for the "deb" package information. I had no idea it was a special version of a tar file. Anyway, thanks again for such a fun app and all of the useful information. -Ken (kapresley) |
Re: ANNOUNCE: Mephemeris - Astronomy Program
kapresley:
I wish you success in getting a 'full' GUI (PyGTK) development/operational environment running on your Mac OSX :) Also, I think that I was a bit too flippant in my description of what a 'deb' file is. Here is a better explanation: http://en.wikipedia.org/wiki/Debian_package Sure enough, under linux the 'ar' command is what you need first in order to 'peel apart' a Debian 'deb' file without using 'dpkg' (the natural choice). Like my README says, I am much more comfortable with 'RPM' files, but was forced to learn a tiny bit about 'deb' due to Maemo. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Hello again folks:
New version released, with only a tiny handful of changes: 2008/10/10 = version 0.99 - implement PyGTK 'toggle' buttons on 'sky plot' window - implement PyGTK 'radio' buttons on 'sky plot' window - fix bug of constellation lines getting dim when grid was activated Yes, I surprised the heck out myself by deciding to finally attack the 'button' issue on the 'sky plot' window -- to eliminate the 'funky' factor :) The result is 'proper' (?) button techniques on that window i.e. 'toggle' and 'radio' buttons. I also changed the wording/labelling a bit. The 'equirectangular' projection sounded too much like the 'equatorial' coordinate system (especially when abbreviated as 'EQU'), so I cheated a bit and have renamed 'equirectangular' into simply 'rectangular'. Sorry for releasing this version so quickly, but when I found out how much it annoyed everyone, and how (relatively) simple it was to deal with it, I decided not to wait. http://darethehair.googlepages.com/software.html P.S. Remember that every update wipes out your custom 'ini' file settings. As well, any custom 'xxx_url.dat' file changes are also vulnerable now. P.P.S. Using toggle/radio buttons instead of my original technique actually *reduced* the the size of the program by 400 lines of code. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Hello again, darethehair! Thanks for the additional "deb" info and clarification.
Oh, yeah, the GUI improvement with version 0.99 with the "real" toggle and radio buttons is definitely much better. I do have one interface question I forgot to ask. If I "dismiss" one of the columns in the sky window (to increase sky viewing area) is there a simple way to bring it back (sorry, I just don't see it mentioned in the docs). Thanks again for all of your great work! See ya around... Ken |
Re: ANNOUNCE: Mephemeris - Astronomy Program
kapresley:
Yes, the 'menu' button toggles the various modes of those controls, so at the beginning of the cycle, all the 'columns' are back again: - Menu (F4) = toggle on-screen controls verbose/spartan/off |
Re: ANNOUNCE: Mephemeris - Astronomy Program

on Mephemeris have a dependancy on python2.5-pgsbt where might I find that? Thanks! |
Re: ANNOUNCE: Mephemeris - Astronomy Program
ebridle:
I am definitely *not* an expert on installing 'gpsbt'. I know that a few people asked and commented on it within this very 'Mephemeris' thread -- have you seen those? There is talk of 'red pill' mode, but I myself used a different technique (it has been a long time since I flashed). If you solve this, let everyone else know too :) |
Re: ANNOUNCE: Mephemeris - Astronomy Program
One version of python2.5-gpsbt is at http://repository.maemo.org/extras/p.../python-gpsbt/
|
Re: ANNOUNCE: Mephemeris - Astronomy Progra
Oops, that got sent too soon. I would think that as long as you have the extras repository, apt-get python2.5-gpsbt would work. I think I downloaded it and either used "install from file" with the application manager or "dpkg -i filename" as root.

Re: ANNOUNCE: Mephemeris - Astronomy Program
Very nice program. I find it handy to have co-ordinates for the planets when observing. I should of picked up this utility earlier.
Is there a way to display the RA in hours instead of degrees? Yes, it's simple math, I just perfer hours. Also, in the sky view none of the toggles seem to work, such as 'names'. Should these buttons work? Again, thanks for the handy program. Now I just need to figure out the satellites feature to keep tabs on the ISS. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Astroguy:
Well, the default mode uses 'horizon' coordinates (degrees), but if you switch to 'equatorial' mode you will get RA in 'hours'. Is that what you meant? The 'toggle' buttons are 'queued'. See the README for clarification (or a few messages back in this thread). It is when you click on the plot to 'refresh' it -- that is when the 'toggle/radio' settings take visible effect. The case of 'names' is also special i.e. it is ignored unless you also have the 'object' toggled on. Note that the 'web window' has a 'satellite position' plot that is, by default, set to the ISS. No, none of the 'web' apps are mine, but this makes it easy to show them :) |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Thanks for the responce.
ah, okay. I was just being dumb and not reading alt/az on the screen! whoops. My brain is hardwired in RA/Dec and that what I saw I was reading. I also saw the post earlier which really helps with usage. Where is the 'readme' file located? I should read that before I ask more questions (and give my head a shake about the alt/az stuff.. doh!) Thanks again. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Astroguy:
There is a link to the 'README' file on the website where the actual program is downloaded. As well, once downloaded, the README file is present in the '/usr/lib/mephemeris/doc' subdirectory. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Gee I feel late to the party here...I have been hoping to see something like this for a while. but I have been obsessing on Ubuntu lately and not paying much attention to the tablet....but thanks very much for this effort!.
I had a nice Astonomy app on my pocketpc prior to retiring it and switching to the N800 and I really missed having something like this. I found the dependencies and got the deb to install. When I try to launch the app it doesn't start up...no flash, no screens nothing. Any thoughts? i just installed the latest version of Diablo and have been getting my favorite apps loaded so things are pretty clean at the moment. Any thoughts would be appreciated. thanks |
Re: ANNOUNCE: Mephemeris - Astronomy Program
kamishki:
I hope that you can try out Mephemeris, so that you can share your thoughts about it later :) Actually, I have no idea why your app doesn't start up properly. No one (including myself) has reported running into such a problem. My suggestion -- if you are able -- is to start it from a shell command line, so that you can view any messages produced. Do you know how to do so -- either on the tablet itself, or remotely connected to a shell via ssh? |

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? |
Re: ANNOUNCE: Mephemeris - Astronomy Program
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! K |
Re: ANNOUNCE: Mephemeris - Astronomy Program
kamishki:
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? |
Re: ANNOUNCE: Mephemeris - Astronomy Program
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! k |

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 :) |

Well, to configure repositories, you need to run: Settings/Application manager Then pick from the menu: Tools/Application catalog Then create/edit as you see fit.

Re: ANNOUNCE: Mephemeris - Astronomy Program
skatebiker:
1) Just so that we are comparing apples-to-apples, provide the repository listing the same way that I did -- what I did (in a terminal) was this command: cat /etc/apt/sources.list.d/hildon-application-manager.list I notice from the Gronmayer repository searcher (http://www.gronmayer.com/it/index.php) that 'python2.5-gpsbt' is in *both* the 'chinook' and 'diablo' repositories, and that (I think) that I only have the 'chinook' one enabled, even though I am running 'diablo'. 2) I am confused -- if you don't have 'python2.5-gpsbt' installed, then there should be no risk of disrupting any applications if you attempt to remove it (in fact you don't even need to try if that is true), so why not go ahead and try the 'install' that I suggested. Are you worried that might disrupt as well? Sorry, I don't know how to 'backup' in case that occurs, but it seems unlikely to me! |

You are still giving me more credit than I deserve to solving problems like you are experiencing :) I was hoping to actually see the 'messages' produced by your attempt to install 'python2.5-gpsbt' from the command line. In any case, three things that I notice about your repository listing that *might* cause trouble (hey, I am just a user like you!) are: 1) You have the 'repository.maemo.org/extras' for *both* chinook and diablo -- maybe try temporarily getting rid of the diablo one (I don't have that one) 2) You have those repositories mentioned *twice* (two for chinook, and two for diablo) -- I think this might be asking for trouble 3) You have the 'repository.maemo.org/extra-devel' for diablo, but I do not (this might be OK) I am personally running out of ideas to help -- like I said earlier, you may want to post your question to a different thread, since this is not directly related to Mephemeris -- simply to your (legitimate) desire to install 'python2.5-gpsbt' on your tablet. |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Folks:
Small changes to the release of version 1.00 of Mephemeris: 2008/11/24 = version 1.00 - add new 'ini' file option to control the resolution of the solar system orbit plot window - add horizontal/vertical pan/tilt option to solar system plot window - fix bug in user-controlled timeout option for 'gpsbt' I have been sitting on these changes for a while, but once I found the small bug mentioned above, it provided sufficient incentive to include the pan/tilt option to the solar system orbit plot window. As before, all your customizations are wiped out when you upgrade. Package and README is still on the same web page: http://darethehair.googlepages.com/software.html Enjoy! I am still curious to know if anyone is actually using it, or it is just a novelty... |
Re: ANNOUNCE: Mephemeris - Astronomy Program
Hello again, darethehair. I am very busy lately, but yes indeed, I still use Mephemeris quite often. I admit, mostly for fun/astronomy hobby, but I often just sit in my easy chair and use it to lookup planet rise/set/info, star information, APOD/other web images, etc. I always check for updates when I get some spare time (scarce lately).
Thanks again and see ya... -Ken |
