Episode 15 features a topic that might sound familiar to you if you've listened to previous editions of Inside Facebook Mobile. It's a project that provides such value to developers that it keeps coming up in discussions with engineers working in many different areas at Facebook. Ezgi has a long-awaited converstion with Mihaela and Pascal about Infer, an open-source static analysis tool with support for Java and C-based languages. Ezgi joined Infer as a natural extension of her PhD in programming languages and type systems. You'll not only hear from her about writing and testing a new analyses for Infer, but also what it's like to balance academic research with having applied industry impact. We're sure you'll stay tuned until the end!
