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! Please do send us feedback! You can reach us via email mobilepodcasts@fb.com, Twitter (@insidefbmobile) or Instagram (insidefbmobile).
