2006-12-11 - Navsys rewrite in C

Writing a prototype for the navigation system in Python got me to learn quite a lot. The architecture of the application is not really set in stone yet, some more things need to be experimented, but the big parts are pretty clear on paper. The most problematic part at the moment is that the refresh rate is not as fast as the GPS points come in. guess I should use some more queues here and there so as to prevent load overrun when drawing takes longer than the time it takes for the GPS receiver to send more points.

Having a functionnal system, I decided to rewrite the whole thing in C. it should appear in CVS in a couple days when I have it to a useable state.

The music player component will have to eventually be rewritten as gstreamer 0.10 has evolved quite a lot from 0.8 that I was using earlier, but, that's what it takes to get much more power and features.

2006-11-07 - performance testing in real life

After some testing, it turns out that the work is a little too much for the tiny epia board. I had to turn displaying of the gps points off (bummer). Perhaps it's due to the architecture of the hackish python version though. This experiment showed me that the ideas in this thing are sound, and just need some refining.

2006-08-25 - Navsys is finally started

I finally have a monitor, so I can hack on the navigation system proper. after much testing, it turns out using postgresql on the carpc is probably the best way to handle data management, so I went that way. my current ideas on the program being a little hazy at the moment, I started writing it in python, so as to be able to do a quick and dirty (tm) implementation.

2005-04-26 - Ngpsd is dead

after seeing how far ESR has taken gpsd, ngpsd isn't of any use anymore. It was an ad-hoc solution as gpsd had fallen in the big pile of rusty code, but the phoenix has risen from the ashes here.

2005-04-20 - Mailing list

I managed to take the time to install mailman, and a mailing list has been set up.

2004-12-01 - CVS is back up

Ok. now that the important work at home is somewhat done (far from finished, but getting there), I took the time to put the cvs repository on the new box, and viewcvs is also back on, with cvsgraph and the ability to download the latest tarball...
Feel free to send me email and participate.

2004-10-12 - CVS is broken

cvs is broken, I know, I didn't get the time to reinstall the cvs tree on the new machine.

Note that this box is at the end of a DSL link, so, be kind :D

2004-06-29 - GUADEC

I'm currently at Guadec, and I will be doing a talk there about Navigation, Cartography and Libre Data (the slides are in the CVS for those who want to check them out).

Today is the release day of two components of the next generation NavSys, ngpsd and sound-server. A new track file format is now used, that stores the error information from certain gps receivers (currently for the Garmin PGRME proprietary sentence). MapEditor was updated accordingly with a new track format loader (we now have 2, which shows how the automatic format regognizer works)

2004-06-10 - Temporary pause

I am preparing to move from a rental appartment to a new appartment I am purchasing, and thus am packing my stuff...
I won't have any time to dedicate to NavSys during this time (from now to june 20th).

2004-05-21 - mapeditor updates (edited)

MapEditor's new version is out, that includes improvements in the track file loading department
all images now have an appropriate thumbnail

2004-05-13 - CVS and ViewCVS

A cvs repository is starting to see the light.
you can browse it through ViewCVS

2004-05-11 - New version of mapeditor

A new version of MapEditor is out, correcting some bugs that were preventing some of it's more interesting uses

2004-05-10 - New site and IRC channel

The new site is up and running, with the menu items currently pointing to the old sites.
If you are interested in NavSys, join us on irc.freenode.net channel #navsys.

currently thumbnails are not thumbnails as I have some issues with my gimp
