    Episode 23: Tales of Shiny in production with Pedro Silva

    One of the common themes seen throughout the Shiny Developer Series is that effective Shiny development is much more than just getting an application to work! Other important considerations include applying Shiny to high-profile projects, ensuring a production-grade code base, and even building robust tooling to assist with development. I have the pleasure of discussing these with Appsilon software engineer and Shiny frontend developer Pedro da Silva! You will hear Pedro's practical advice on the many developer-friendly packages and tools he uses for production Shiny development, a detailed walkthrough of his (Shiny contest) award-winning Shiny Decisions application, and his recommendations for taking your Shiny development skills to the next level.

    Episode 29: Playing fair with the FairSplit Shiny App

    Whether in a sports pickup game or a different friendly competition, we often strive for balancing the distributions of skills so everyone can have fun. What does this have to do with Shiny? In episode 29, our coverage of the 2021 Shiny contest continues as I am joined by Douglas Mesquita and Luis Gustavo Silve e Silve who created the novel FairSplit Shiny application! Motivated by regular football pickup games, Douglas and Luis developed a novel algorithm to balance the distribution of individuals incorporating multiple traits that eventually wound up into a snazzy Shiny app that easily has something for everyone. This is yet another example of the many use cases Shiny brings at your fingertips.
