I am fortunate enough to attend an IT conference related to Java developers called Geecon.
I attended it a few years back thanks to my previous employer, and I was equally excited to visit it again.
The first day turned out to be a catch-up event with people I know from the past and who work now in different company.
The point is, always make the time to network and meet other people during a conference.
Learning is great, but also networking can help you go further.
