Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

Cassie Shum discusses the architectural evolution of GraphRAG and why data foundations are critical for advanced AI workflows.

Congrats, Jack! I bet you have some great stories to tell about your company being acquired by Microsoft. Microsoft has changed so much. Now, they're involved in open source. And, how about the free upgrade to Windows 10! Puget Sound must be a wonderful area to live. I see you're involved in theater. Would you consider giving a video talk and posting it on YouTube with a link here?
Nice site, By the way! http://www.jackpines.info/
Chris Schaefer is the new JUG leader in Sarasota and he's a nice guy who knows his stuff, especially about Spring. Plus, he's a brewmaster. Look forward to lots of good times.
Hi Jack, Glad you could join us. OJUG meets every 4th Th except this month. I'll put meeting announcements in the Codetown Events section. BTW, tonight is a fun event to take the place of this month's local meeting - a beer and meetup night in Sarasota.
Life's better without braces,
Mike
