No previous experience necessary, just tell me what you want to talk about or suggest a range of topics if you aren't sure. The provisional list of speakers for this conference includes Guido van Rossum, David Abrahams (Boost Python), Andrew Koenig, Marc Andr=E9 Lemburg, and many more. See http://www.accuconference.co.uk/ for more about the conference. *** Call for Participation *** UK Python Conference 2003 April 2-3 2003 Holiday Inn, Oxford The UK Python Conference 2003 is being held in conjunction with the larger ACCU conference. The conference will include two days of papers arranged in 90 minute speaking slots with either one or two tracks. The audience is highly technical and will include experts in many fields of computing, some of whom may know little or nothing about Python. Talks will be welcomed on any aspect of Python, but we are especially interested in the following: - Commercial applications for Python - Cross-language talks Speakers are welcome from the UK or the rest of the world, however our budget for overseas speakers may be limited. Speakers get reasonable travel and accomodation costs paid as well as free attendance at the Python conference and the associated ACCU conference. To submit a proposal, send an email message to duncan@rcp.co.uk by 2nd October 2002. In your message, please include the following: - Speaker name and affiliation - Contact address - Presentation title - A one paragraph abstract -- Duncan Booth duncan@dales.rmplc.co.uk int month(char *p){return(124864/((p[0]+p[1]- p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure? http://dales.rmplc.co.uk/Duncan
