Adam Warski, the co-founder and CTO of SoftwareMill, discusses Scala programming and the Tapir library. Scala is a general-purpose JVM language, and Tapir is a back-end library used to describe HTTP API endpoints as immutable Scala values. Host Philip Winston speaks with Warski about the implications of Scala being a JVM language, the Scala type system, the Scala community's view of functional vs. object-oriented programming, and the transition of the ecosystem from Scala 2 to Scala 3. The Tapir discussion explores why Tapir is a library and not a framework, how server interpreters work in Tapir, how interceptors work, and what observability features are included with Tapir.

Dan Lorenc, CEO of Chainguard, a software supply chain security company, joins SE Radio editor Robert Blumen to talk about software supply chain attacks. They start with a review of software supply chain basics; how outputs become inputs of someone else's supply chain; techniques for attacking the supply chain, including compromising the compilers, injecting code into installers, dependency confusion, and typo squatting. They also consider Ken Thompson's paper on injecting a backdoor into the C compiler. The episode then considers some well-known supply chain attacks: researcher Alex Birsan's dependency confusion attack; the log4shell attack on the Java Virtual Machine; the pervasiveness of compilers and interpreters where you don't expect them; the SolarWinds attack on a network security product; and CodeCov compromising the installer with code to insert exfiltration of environment variables into the installer. The conversation ends with some lessons learned, including how to protect your supply chain and the challenge of dependencies with modern languages.

Jeff Perry, career coach with experience in multiple engineering and technology fields discusses how software engineers can be intentional and proactive in evaluating and pursuing career options, with host Kanchan Shringi. Perry shares examples of how engineers have made shifts to opportunities that took advantage of their skill sets. The conversation then tackles the importance of building a personal brand and the role of mentors and coaches.

Jonathan Shariat, coauthor of the book Tragic Design, discusses harmful software design. SE Radio host Jeremy Jung speaks with Shariat about how poor design can kill in the medical industry, accidentally causing harm with features meant to bring joy, what to consider during the product development cycle, industry-specific checklists and testing requirements, creating guiding principles for a team, why medical software often has poor UX, designing for crisis situations, and why employing deceptive design patterns (also known as "dark patterns") can be bad for products in the long term.
