Codetown ::: a software developer's community
Every Java developer, in fact every software developer should have the opportunity to attend a technical conference every year or so. Increasingly, software conferences like Java One (now Code One) are becoming more broad and including multiple technologies. Ian Darwin is now publishing a great calendar of Java-related conferences. Here's the link: https://darwinsys.com/java/conferences.web Thanks, Ian!
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.

According to the study, this insight could pave the way for new techniques to reduce hallucinations and build more trustworthy AI systems, but not all agree on what hallucinations are in the first place.
