I did an online presentation about PCI and Credit Card Security for BSSUG last night and it went pretty well, with one minor pain point – at very points in the presentation I was hearing myself on about a 1 second (or it seemed) delay. I was using my phone and a Bluetooth headset and thought maybe it was the room acoustic on my side but we finally figured out it was the open microphone in the room on the other side. No audio issues for them, just for me. When we finally muted that…nice to only hear myself once! One more lesson learned.
