Richard Feldman hosts Software Unscripted, a weekly podcast that feels like pulling up a chair next to a fellow developer who’s seen it all. The conversations here are off-the-cuff and genuine, delving into the realities of writing code, navigating tech trends, and the often-unspoken challenges of building software. Rather than rigid interviews or dry lectures, each episode unfolds as a natural dialogue, exploring the intersection of technology, continuous learning, and the news shaping our digital tools. You’ll hear discussions that range from practical programming techniques and language debates to broader observations about the industry’s direction, all through a lens of lived experience. This isn't about polished presentations; it's about the authentic, sometimes messy, process of thinking through problems and sharing insights. For anyone who spends their days deep in logic and syntax, this podcast offers a relatable and thoughtful space to reflect on the craft. Tune in for a candid and engaging take on the world of software, one unscripted conversation at a time.
