We, at some point, had a Knowledge Sharing event every week. The goal was just go round the table and every developer would share something they learned that week. As I was the senior developer at the time I would usually bring something that I learned or from CS, like a nifty algorithm or how Hashmaps are implemented in C#. Other people would share some bugs or unexpected behaviour. I liked it a lot and I felt that the team did as well. Sadly we stopped doing it, as there was a reorganisation that impacted our ability to do it.
