Tech Talks

CED Tech Talks focus on development technology and its application. They are a way to make CED’s internal technical knowledge available to our members and supporters, as well as potential members and others outside our organisation.

They consist of a 45-minute talk followed by about 30 minutes of questions and answers and subsequent discussion, recorded from the initial Zoom meeting. Contact us if you would like to attend future Tech Talks with us on Zoom.
