The SoCal Piggies group came into existence when Southern California-based Pythonistas responded to a "trying to organize LA/OC Python Interest Group" [http://agiletesting.blogspot.com/2005/02/la-piggies-trying-to-organize-python.html blog entry] posted in February 2005 by Grig Gheorghiu. Grig offered to host the Wiki for the group, and Titus Brown created the group's mailing list. Titus hosted the group's first two meetings at the KML Marine Lab in Newport Beach. Daniel Arbuckle has been hosting the meetings at USC.
Here are some short introductions added to the Wiki by various Piggies, along with their preferred meeting locations:
Grig Gheorghiu
I live in the LA area (Rancho PV) and work in Irvine, at Avamar, a software development company in the disk-to-disk backup/restore field. I work as a tester and I write all my automated tests in Python. I also use Python for things such as creation of large data sets to be used as inputs in my testing (mostly cross-platform, but also very specific things like Exchange folders/messages, Oracle/SQL Server databases, etc.); distributing and running the tests on multiple machines/OSes and collecting the results in a central place (via STAF/STAX); running acceptance tests (via PyFIT/FitNesse). I'm very interested in agile methodologies (AKA Extreme Programming) and I'm trying to apply some of these principles in my day-to-day work.
Titus Brown
I live & work in Pasadena. I have a car and am OK with picking up people at USC if we do something down in Irvine. Once a month sounds like a good initial frequency, since at the moment I'm trying to GRADUATE.
Re meeting location -- I have access to both the KML Marine Lab (http://www.its.caltech.edu/~mirsky/kml.htm) in Corona Del Mar/Newport Beach and several places on Caltech campus (in Pasadena). The Marine Lab has a place for BBQs, a meeting room, wireless network, parking, etc. Caltech doesn't have an obvious BBQ place ;).
Oh, and I can bring a projector in case anyone wants to do a presentation.
Greg McClure
I live and work in Newport Beach and attend UCI part-time, so I'm pretty flexible too. Obviously, Irvine/Newport/CDM is great for me. Once every other week might be good for me, but I have a funny feeling I would default to once-per-month once things got rolling, unless the group was really active about presentations or some group project or something. Thursday's almost always bad for me, but I'm flexible on other days. I like SoCalPiggies, too, or if we wanted we could all get leather jackets and call ourselves "The Southern California Pigs", and then after SCPig meetings we could all go out and rumble with Perl weenies.
Malachi Clark
I live and work in the Irvine/Costa Mesa/Newport area, so, that is the best for me. But if in the evening, I might be able to make it further north. I like the one night a month to start with idea, unless it gets really rolling. A weekday lunch could work too, but that would have to be in OC for me to make it.
Daniel Arbuckle
I live and work at the USC campus, and since I don't have a car, its important to me that the meeting place be accessible from there by bus. I've been offered a ride if the meeting place is in Irvine. It's possible I could get an on-campus meeting room for us, as well. As to meeting frequency, I would say once a month, unless the group turns out to be very active and interesting.
Lynn Blickenstaff
I live and work in NE LA -- Eagle Rock. Meeting once a month sounds good to me, although wouldn't be able to attend very often in OC.
Brian Luft
I work downtown for a small but prominent web hosting company. Most development work is being done in PHP5 but I am finding ways to infuse Python into the organization. I've always liked Python for its train-of-thought friendliness and quick turnaround time. I believe in the power of open source to expand opportunities and to provide technologies to those less fortunate (= most of the world IMHO). I'm into sports, biking/hiking/camping, music, and will always be happy to take your money at a poker table 
Steve Ruiz
I live in Fullerton and work in La Mirada. Newport or Los Angeles are equidistant from me but Santa Monica is a journey. Once a month meetings sound good. I can make evening meetings Monday though Thursday but prefer Thursday.
Steve Anderson
I live and work in the Anaheim area. I would prefer meeting some place in OC. I think once a month sounds good. Though, between travelling for work and my general laziness though, you shouldn't count on me being reliable.
Josh Lucas
I live in Monrovia and work in Pasadena but I'm more than willing to drive a bit once a month. I'm signed up with the Pasadena Meetup but that's never actually met so hopefully the SoCal Piggies will have better luck.
Manuel Garcia
I live in Fountain Valley, near Santa Ana in Orange County. Irvine is mentioned a lot as a possible meeting place, and that is pretty darn close. Once a month sounds like a good frequency.
George Bullis
I live in Glendora, and I work in Monrovia. 12 meetings a year sounds like a good start to me. Thursdays are usually booked for me.
Charles Hornberger
I live in Echo Park, near downtown LA, and work at Caltech in Pasadena. Monthly sounds good; LA is preferable to OC for me (though I'm willing to drive ... just not at rush hour).
Steve Petrovits
I am Steve Petrovits millionaire/secret agent, I own a mansion and a yacht (seriously). The reality of the situation is I'm an East coast guy, on the West coast. I'm originally from N.Y., I moved to California when I was 25. I live in Encino with my beautiful, bitchy, girlfriend Crystal. I'm a mulitasking, sarcastic, caffeine addicted, Motion Picture Set Painter by profession (not by choice, my deal with the money faerie fell through). I'm a computer hobbiest, *nix proponent, python user, and a billion other things too numerous to list. While not computing/coding/irc/sleeping I enjoy action adventure movies, trance music, scifi/fantasy paperbacks, pretending my bills didn't actually arrive in the mail, and eating. I'm not the most adept python coder, I'd evaluate my skill level to be somewhere between advanced beginner and intermediate, but I manage. I'm currently not involved with any python projects atm, although have been in the past. I'm looking forward to any social python interaction/projects/alcohol/etc.. thats all for now.
Morten Bagai
I live in Echo Park near Dodger Stadium and work as a web developer/project manager in Whittier, east of L.A. Born and raised in Denmark, but have been living in L.A. for two and a half years now. Just learned about this group here in mid November 2005, and look forward to attending upcoming events. At present I'm using Python on a daily basis for web development and various administrative tasks. Python is something that had been lingering in my mind for a long time as something I should be using, but it wasn't until I discovered the CherryPy web development framework that I really made the jump. Right now, I'm deploying a site based on the excellent Django framework, and generally working hard to advocate/implement conversion of all our web projects to Python.
Steve Wedig
In 2003 I came to LA for grad school as a phd student in UCLA's CS department. Prior to that I went to Santa Clara University up north. I'm generally interested in applying AI to the web and related stuff. Recently (2005) I was an intern at Yahoo! Research for about 6 months. Now I'm looking to continue refining my Python skills and get into Zope 3 web application development. If I had any free time I would theoretically enjoy poker, ultimate frisbee, alcohol, and most other things. My email is stevewedig at gmail dot com.
