Lucas and Luna explore why OCaml, a language born in the 1990s, is quietly becoming the backbone of high-stakes financial systems. They examine its role at Jane Street Capital, where OCaml handles $5 trillion in daily trading volume, and contrast it with Rust's approach to safety. The episode also touches on why OCaml's strict typing catches bugs that cause billion-dollar losses in other languages. A must-listen for developers curious about functional programming in production.

Google's Carbon language was introduced in 2022 as a potential successor to C++. As of mid-2026, where does it stand? Lucas and Luna examine Carbon's design goals, its interoperability with existing C++ codebases, and the challenges it faces in gaining adoption. They discuss the open-source community's response, the role of Google's internal use, and why replacing a language as entrenched as C++ is a multi-decade project. Specific numbers: Carbon's initial announcement GitHub stars, current commit velocity, and the size of the C++ codebase it targets.

In this episode, Lucas and Luna explore why SQL remains the most underrated skill for developers in 2026. They break down how SQLite processes over one trillion queries per day, why modern tools like DuckDB are making SQL relevant for data science, and how knowing window functions can separate a junior from a senior engineer. They also discuss the rise of SQL-based analytics in fintech and how companies like Stripe use SQL to run real-time risk models. If you've been ignoring SQL, this episode will convince you to reconsider.

In this episode, Lucas and Luna explore how WebAssembly (Wasm) is moving beyond the browser to reshape cloud computing. They focus on a specific case: the rise of serverless Wasm runtimes like WasmEdge and Fermyon Spin, which are enabling faster cold starts and language-agnostic microservices. Lucas explains how WebAssembly reduces container overhead by 50-70% in certain workloads, citing a 2025 Cloud Native Computing Foundation survey showing 45% of cloud infrastructure teams now experiment with Wasm. Luna challenges whether Wasm can replace containers entirely, and they discuss real-world adoption at companies like Adobe and Shopify. The hosts also touch on the upcoming WebAssembly GC proposal and its impact on Java and Python developers. A donation segment is woven in naturally.

Episode 37 of The Programming Languages Podcast dives into Zig, a systems programming language that's gaining traction in 2026 for its simplicity, safety, and performance. Lucas and Luna explore why Zig is challenging C and Rust, its unique approach to memory management, and how it's being adopted in embedded systems, game development, and tooling. They discuss the language's zero-cost abstractions, compile-time execution, and its role in reducing undefined behavior without a garbage collector. With concrete examples from the Godot game engine and the Bun JavaScript runtime, this episode explains why developers are choosing Zig for projects requiring fine-grained control and reliability. If you're curious about the next big thing in systems programming, this conversation covers what makes Zig different from its predecessors and where it's headed.

Episode 36 of The Programming Languages Podcast examines Mojo, the new language from Modular AI that aims to combine Python's usability with C-like performance for machine learning workloads. Lucas and Luna break down Mojo's unique 'syntactic sugar plus MLIR' approach, why it's not just another Python competitor, and what the 2026 ecosystem looks like — including the just-released Mojo 1.0 standard library. They explore concrete benchmarks (up to 35000x speedup on certain matrix operations), the controversial decision to keep Mojo closed source, and whether it truly threatens Python in data science. The conversation also touches on Mojo's borrow checker (Rust-like memory safety) and how it integrates with existing Python tooling like NumPy and PyTorch.

Lucas and Luna explore why Lua, a lightweight scripting language from the 1990s, has become the secret engine behind game modding, embedded IoT, and even Redis scripting in 2026. With 1.5 billion devices running Lua via the Corona SDK alone, they break down its design philosophy of minimalism, its surprising role in the Roblox ecosystem, and why it's gaining new traction in constrained environments like ESP32 microcontrollers. They also discuss the trade-offs—why Lua isn't for large-scale applications—and where it sits alongside Python and JavaScript in the modern developer's toolkit.

Lucas and Luna drill into a single concrete number: PostgreSQL's 40 percent market share growth among new deployments in 2026. They trace how the database went from an academic underdog to the default choice for AI workloads, real-time analytics, and mission-critical OLTP. The hosts walk through three specific drivers — the pgvector extension for vector search, the rise of managed Postgres on cloud providers, and the collapse of the Oracle-to-SQL Server duopoly in enterprise. They also touch on the surprising role of Notion, which moved its entire 100-plus terabyte infrastructure from MongoDB to Postgres in 2025. If you are choosing a database for your next project, this episode gives you the specific reasons why Postgres might be the pick for 2026.

Kubernetes changed how we deploy software, but few people talk about how it changed the languages we write that software in. This episode explores Kubernetes as a language forcing function — why Go became the lingua franca of cloud-native infrastructure, how Rust carved out a niche for performance-critical components, and why Python and JavaScript had to adapt rather than lead. Lucas and Luna walk through the design decisions that made Go the default for kube-native tooling, the rise of eBPF as a Rust use case, and what the Kubernetes API design philosophy means for language adoption in 2026. They also consider whether the next wave of infrastructure languages will emerge from inside or outside the Kubernetes ecosystem. Specific examples include the Operator pattern, the contribution of projects like Krustlet and KubeVirt, and the surprising role of CUE in configuration.

Gleam is a statically typed language that compiles to Erlang's BEAM virtual machine, bringing the reliability of Erlang and Elixir to developers who prefer a Rust-like type system. In this episode, Lucas and Luna explore how Gleam's strong types and simple syntax are making BEAM languages accessible to a new generation of programmers. They examine real-world adoption at companies like Bluetau and how Gleam fits into the growing ecosystem of typed functional languages. The episode also covers the language's unique approach to pattern matching, its interop with existing Erlang and Elixir code, and why its v1.0 release in 2025 is gaining traction among developers tired of JavaScript's complexity.
