The Story of Visual Studio Code
We’re back in NYC at Microsoft Connect(); talking about the backstory of Visual Studio Code with Julia Liuson (Corporate Vice President of Visual Studio), Chris Dias (Principal Program Manager of Visual Studio and .NET), and PJ Meyer (Product Manager).
We talk about the beginnings of the Visual Studio product line, how Microsoft missed the internet, how the community is judging Microsoft and looking at them with a very old lense, how Visual Studio Code evolved from lessons learned with their cloud based editor called Monaco, how they had to radically change to reach developers beyond Windows, and how this open source project is thriving.

Bisq, the decentralized Bitcoin exchange
Chris Beams joins the show to talk about Bisq, the P2P decentralized Bitcoin exchange and open-source desktop application that allows you to buy and sell bitcoins in exchange for national currencies, or alternative crypto currencies. We get some background on the issues faced by crypto exchanges like CoinBase, and the now defunkt Mt. Gox. We discuss whether or not Bitcoin is a censorship resistant payment system and what it means to have anonymous transaction currency options. Bisq also has an interesting white paper about its own DAO (Decentralized Autonomous Organization) to support its contributors and we discuss that in detail at the end of the episode.
