Hey! Less of the "went"! :-) The OpenSkills SkillsBase uses a Smalltalk OODB called GemStone in production, and as it happens I will be giving a talk about this at Linux World / Smalltalk Solutions in Toronto in a couple of weeks time: http://www.lwnwexpo.plumcom.ca/smalltalk.cfm ... and because of my current interest in OODBs I'm very much looking forward to hearing what Christof has to say on Wednesday.

I met him when he was in Sydney in January. I got word that he's going to be back in town this week, and a few weeks back asked Lindsay if he was looking for a topic for DebSIG this month. Not every day a businessman decides to GPL his product. OODBMSes came and went as a technology in the late 80s/early 90s, so you might be saying WTF? Those efforts largely face planted because they tried to create a generic object syntax and a complicated meta query structure rather than working in the native syntax of {insert your OO language here}. db4o is really rather different. It is trivially easy to use and surprisingly robust. For me, working in Java on Linux as I do, it has given me a reliable persistence store for my applications without any of the usual object-relational mapping nightmare that would crop up if I were to try and use a more traditional RDBMS. While their primary market is embedded devices, this is not limited to phones and what not like you might think. I gather that one of their earliest clients uses db4o as the live datastore underneath the signalling system for an entire metropolitan railway, which I gather involves insane numbers of objects per second. Pretty cool - and if it does that then I'm quite certain it can handle the stuff I throw at it. Anyway, Christof is a lovely fellow and presents well. You should enjoy his chat so I encourage you to stop by the new debsig location. And thanks to openskills for gatecrashing their party.

Hey Ashley, Really sorry about the clash. Unfortunately the speaker was only in the country this week, so we had to hold the meeting out of the normal timeslot. I'm still going to organise a meeting for the 3rd Wednesday, so you're not going to miss out on your DebSIG goodness. :-) Cheers, Lindsay -- http://slug.org.au/ http://lca2007.linux.org.au/ http://holmwood.id.au/~lindsay/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

OpenSkills is the 2nd Wednesday of the month so this will clash, for those of us who like to attend both.
