Re: [Java-player-users] Second bug in FiducialInterface.java in javaclient 1.6.4

[Radu B. R. <ru...@cs...>]

Hey Shane,

Wow, you were really fast at reporting, identifying and correcting the 
problem. :) Sorry, but I just managed to read my e-mail. I wish I could 
have done it sooner to help you out.

Anyway, it seems that you got that one sorted out. Can you please send 
me a diff file so I can commit it to the CVS repository ?

Yes, I totally agree that we should have more examples on how to use 
Player/Stage with or without Javaclient. I am willing to help anyone who 
wants to write some with technical aspects, but I just don't seem to 
have the time to sit down and do it myself :(

We could also use ideas and/or code contributions for the other parts of 
the client.

PS. I just realized that I have some old hacked code lying around on 
some of my web pages. Maybe it could be useful for any of you who are 
using Javaclient and want to get into neural networks as well (Joone). 
The source codes are really crappy because I had to move and didn't get 
around to fix them, but if somebody wants to actually clean them up, we 
could post them on the Javaclient examples web page (which is empty 
right now - I think). Anyway, the URL for the source codes (including a 
small tutorial) is 
http://www.robotux.info/ai/included/read.php?cat=neural&article=Radu%20Bogdan%20Rusu_On%20Data%20Fusion%20Methods%20Using%20Neural%20Networks,%20From%20a%20Practical%20Implementation%20POV


Thanks,
Radu.
