Optimizing is a podcast produced by Professor Barry Dwolatzky (also known as "The Grand Geek"). Season 2 features Prof Barry and Kerryn Gammie in conversation with thought leaders and role models in the South African and African digital community. Each conversation is based on the metaphor of a relay race in which the guest is asked to reflect on how they received the baton and what they will pass on to Kerryn and her generation [Evan Wigdorowitz (Edit and Logo Design); Callum Kuhl (Music )]
S2:Ep13 - Epilogue
Season 2 of the Optimizing podcast has come to an end. Prof Barry Dwolatzky and his co-host Kerryn Gammie have presented 12 episodes in which they have conversations with leaders, role models and influencers in the Digital Economy in South Africa, Africa and the World. The metaphor in this season is "life as a relay race" and each guest was asked to pass "batons" to Kerryn and her generation of future leaders. In the epilogue Prof Barry and Kerryn reflect on these conversations and review the batons that were passed on.

Customer ReviewsSee All
so far so good
Full disclosure, I know Prof. Barry and consider him a good friend. But that is how I trust the podcast will hit listeners. He will quickly become a good and wise friend. Barry is every bit as kind, thoughtful and direct in every day situations as presented here. I’m an even older computer scientist. I lived the world of computing he describes in episode one. Episode two made me proud to count Barry among my friends. Heroes and resistance, heinous brutality and death are a part of the lives of too many South Africans of my generation. I am glad that Barry told his story. I can’t wait for what comes next.
