Forty six years later, Trenton Computer Festival (TCF) returns. It’s still free, and still welcomes all levels of expertise, and still run by Allen Katz. Yet again for another year, it is online.

New this year: an environmental theme, as arranged by Karen Johnson, co-program chair. Frank Niepold of NOAA speaks at 10:15 a.m and Bob Kopp, co-director of Rutgers Climate Impact Lab, speaks at 3:40, but as before – a dizzying array of workshops are available.

Go to the TCF website to choose from 50 workshops including “How Computing is Changing Photography” to “How to Communicate for Climate Change — Challenges.” One of the names I recognize is John LeMasney, who is known for explaining tough technical skills to novices like me. On March 19 he speaks at 12:25 on a topic that continues to plague many of us — how to recycle electronic waste.
