Just as the subject says... you guys (everyone involved with TM) are my heroes. Problem: I needed to develop a TCP server that could serve multiple GPS tracking devices over GPRS. These devices uses a multi-level (structures within structures) style binary protocol. I looked at various possible solutions which handled the complex asynchronous processing while I could concentrate on implementing the protocol. Time was of the essence (as it always is). Solution: I finally ran into Twisted Matrix and it immediately looked very promising. Only problem was that I didn't know Python at the time and looking at it for the first time I couldn't make heads or tails out of it. (I come from a Delphi background but knows a bit of C, PHP and Java as well). Anyway, after about a week of straining the old brain I not only managed to learn the basics of Python, but wrote my first concept server in TM and through it all learned to come to love both of these solutions very much! Final Verdict: About a month down the line my now completed server is running as smooth as butter handling an ever growing number of unit's just lovely. The data, once parsed is all pushed to a Apache/PHP based server via XML-RPC which in turn performs all the database related stuff. Thanks for all your hard work guys, it is noticed and deeply, deeply appreciated! Kind Regards, Don Schoeman
