In this episode, Tom and Sherif cover a few housekeeping items, offer a quick update about Ukraine that will soon be supplemented by the tardy publication of a previously recorded episode, and discuss the deterrent impact of the Biden White House's new export controls on cutting edge semiconductors. We also stumble upon a joke of opportunity related to fine Champagne.
