The second post in a three-part series on PyCodeConf speakers highlights several influential figures in the Python community and their open-source projects. Armin Ronacher, a founding member of the Pocoo team, is known for developing Flask and Werkzeug, and his talk is titled "Cherry-picking for Huge Success." Leah Culver, co-founder of Convore and co-author of OAuth, created Django-Elsewhere and the Python-OAuth library and will speak on using Backbone.js and Django for a faster web UI. David Beazley, author of the Python Essential Reference, developed PLY, a Python Lex-Yacc parsing tool, and his presentation focuses on "Embracing the GIL." Craig Kerstiens, founder of Registry Stop, created Python Google Analytics and will discuss "The State of Packaging and Dependency Management." Kenneth Reitz, an open-source architect, developed Requests and Clint, and his talk is on "API Design and Pragmatic Python." The post encourages readers to engage with these projects and join the conference in Miami.
