The Programming Languages Podcast with Fexingo: Python, Rust, JavaScript, and Modern Coding

Go, the language born at Google in 2009, has become the backbone of cloud-native infrastructure. In 2026, Go's adoption for building microservices, CLI tools, and Kubernetes controllers is at an all-time high. Lucas and Luna explore why Go's simplicity, goroutines, and powerful standard library make it a top choice for backend developers, even as Rust gains traction for performance-critical systems. They break down the latest CNCF survey showing Go's dominance among Kubernetes developers, compare its approach to error handling with Rust's, and discuss how Go's generics (introduced in 1.18) have matured. This episode also looks at the future of Go: can it maintain its position as the default cloud language, or will newer languages like Zig or Carbon challenge it? A must-hear for any developer choosing their next backend stack.

In this episode of The Programming Languages Podcast, Lucas and Luna dive into COBOL — the old-school language that still processes trillions of dollars in transactions daily. They explore why COBOL remains crucial in banking, insurance, and government systems, and examine the 2026 modernization trend where new tools like AWS Mainframe Modernization and IBM's Watsonx are bridging old and new code. Learn why 'extend and embrace' is the strategy, why COBOL programmers are still in high demand, and how open-source initiatives like GnuCOBOL are keeping the language alive. A must-hear for any developer curious about the backbone of global finance.

Swift has long been seen as Apple's language for iOS and macOS apps, but in 2026 it's breaking out of that bubble. According to the 2026 Stack Overflow Developer Survey, Swift server-side usage jumped 40% year over year, and the TIOBE index placed it in the top ten for the first time. In this episode, Lucas and Luna explore how open-source efforts, frameworks like Vapor, and initiatives like Swift on AWS Lambda are driving adoption beyond Apple's ecosystem. They discuss real-world cases — from Airbnb's backend to serverless functions — and weigh Swift's performance, concurrency model, and memory safety against rivals like Go and Rust. The conversation also touches on the challenges: remaining developer skepticism, Apple's influence, and the need for a wider community. If you're a developer curious about where to invest your learning time, this episode gives you the concrete data and context to decide whether Swift is more than a niche language in 2026.

In this episode of The Programming Languages Podcast, Lucas and Luna dive into why Dart and Flutter have become a dominant force in cross-platform development by mid-2026. They start with a surprising stat from the latest Stack Overflow survey: Flutter has overtaken React Native in developer satisfaction and is now used by over 15 million developers worldwide. Lucas explores how Google's investment in Dart, originally launched as a JavaScript alternative, paid off by creating a seamless mobile-web-desktop experience. They discuss a case study of a startup that migrated from React Native to Flutter and reduced app size by 30 percent while improving performance. Luna explains why Dart's just-in-time compilation during development and ahead-of-time compilation for production sets it apart. They also cover the challenges of learning Dart for developers coming from JavaScript or Java. The episode wraps with a look at Flutter's expanding role beyond mobile, into embedded systems and desktop apps. Plus, a brief listener support mention. Specific, actionable insights for developers evaluating cross-platform frameworks.

In this episode, Lucas and Luna dive into Mojo, the new programming language from Modular that promises to combine Python's ease of use with C-like performance for AI workloads. They discuss a benchmark showing a 3000x speedup over pure Python on matrix multiplication, the auto-tuning compiler that optimizes kernels for specific hardware, and the challenges of ecosystem maturity. Featuring insights from founder Chris Lattner, the episode explores whether Mojo can become the go-to language for machine learning engineers who want to avoid writing CUDA.

In March 2026, the White House Office of the National Cyber Director released a report urging the shift to memory-safe languages for critical infrastructure. Rust, with its borrow checker and zero-cost abstractions, is leading the charge. This episode explores how Rust is being adopted in the Linux kernel, by major tech companies like Google and Microsoft, and by the Department of Defense. We discuss the learning curve, the growing ecosystem, and why Rust is poised to become the default for systems programming. If you've been curious about Rust's real-world impact, this episode gives you the concrete numbers and case studies to understand its rise.

In this episode of The Programming Languages Podcast with Fexingo, Lucas and Luna explore the rise of polyglot programming—where developers use multiple languages in a single project or career. Anchoring on the 2026 Stack Overflow survey showing 62% of professional developers now use more than one language, they discuss the drivers behind this shift: the need for performance and productivity trade-offs, the impact of containerization and language interop tools like PyO3, and the growing salary premium for polyglots. They also examine how modern computer science curricula and bootcamps are adapting, and whether AI-assisted coding will reduce or accelerate the trend. The episode includes a real-world example of a fintech app combining Rust, Python, and JavaScript, and ends with a reflection on the future of the 'language orchestrator' developer.

In 2026, R has climbed back into the TIOBE top 10 and its package repository CRAN now hosts over 23,000 packages. Lucas and Luna explore why this 30-year-old language is still essential for data science, from the tidyverse and Shiny dashboards to its dominance in biostatistics and academic research. They discuss the role of Posit (formerly RStudio) in building a reproducible ecosystem, and how R's unique strengths—like native data frames and built-in statistical modeling—keep it relevant even as Python expands. If you thought R was fading, this episode will change your mind.

Python 3.13’s free-threading experiment has become production-ready in 2026, and early adopters like Dropbox and Reddit are reporting 3x–4x throughput gains on server-side workloads. This episode breaks down how the Global Interpreter Lock was finally made optional, what it means for existing single-threaded code, and why the biggest impact isn’t on AI models but on everyday web services. We also look at the tooling caveats – C extensions, thread safety, and the mental shift required to write truly concurrent Python. For tech leads evaluating Python for 2026 projects, this is the one change that could tip the balance.
