WebAssembly, or Wasm, is no longer just a niche tool for browser gaming. In 2026, it's running server-side functions, powering edge computing, and even replacing containers in some deployments. Lucas and Luna dive into the specific numbers: over 70% of cloud providers now support Wasm runtime, and how companies like Cloudflare and Fastly are using it to reduce cold-start latency from hundreds of milliseconds to under 10. They discuss the security advantages of sandboxed execution and how languages like Rust, C, and Go are compiling to Wasm for portable, high-performance code. If you've been hearing about WebAssembly but aren't sure why it matters, this episode breaks down the concrete shifts driving its adoption right now.

In this episode of The Programming Languages Podcast, Lucas and Luna dive into Julia — the high-performance language that's quietly reshaping scientific computing, data science, and machine learning. They explore why Julia's just-in-time compilation and multiple dispatch make it a compelling alternative to Python for numerical work, and discuss how the Pumas project is using Julia for pharmaceutical modeling at scale. They also touch on Julia's growing package ecosystem and its adoption in fields like climate science and quantitative finance. If you're a developer curious about where scientific computing is heading, this episode offers a concrete look at one language leading the charge.

Episode 78 of The Programming Languages Podcast explores Haskell's unexpected resurgence in production environments. Lucas and Luna break down why companies like GitHub, JPMorgan Chase, and a European airline are adopting this purely functional language for critical systems. We focus on the concrete case of a legacy Spark pipeline at a major bank being rewritten in Haskell — cutting infrastructure costs by 40% and eliminating runtime exceptions. We discuss how Haskell's strong type system, laziness, and purity reduce debugging time and enable safer concurrency. We also touch on the rise of the Haskell IDE, GHC 9.12's performance improvements, and the growing adoption in fintech, healthcare, and blockchain. No theoretical jargon — just the real reasons developers are giving Haskell a second look in 2026.

In this episode of The Programming Languages Podcast with Fexingo, Lucas and Luna explore why Lua, a lightweight scripting language created in 1993, remains the hidden backbone of modern game development. They discuss how game engines like Roblox and World of Warcraft embed Lua for modding and customization, the language's unique design trade-offs (no native classes, 1-based indexing), and why its performance profile makes it ideal for real-time interactive systems. Lucas breaks down the technical reasons behind Lua's popularity—its C API, tiny footprint (under 300KB), and incremental garbage collector—while Luna questions whether newer alternatives like Python or JavaScript could replace it. The hosts also touch on Lua's use in non-game contexts like Redis scripting and embedded devices. A donation segment highlights how listener support keeps the podcast ad-free.

In this episode, Lucas and Luna dive into Elixir—a language that's quietly becoming the go-to for building fault-tolerant, real-time systems. They explore how Elixir's actor model, built on the Erlang VM, allows companies like Discord and Pinterest to handle millions of concurrent users with minimal downtime. The conversation focuses on Discord's migration from Go to Elixir in 2023 and how that decision shaped their architecture for handling 25 million daily voice users. Lucas breaks down the technical specifics: how Elixir's lightweight processes, OTP (Open Telecom Platform), and supervised trees enable self-healing systems. Luna challenges whether Elixir's niche is too narrow outside of messaging and gaming, and Lucas counters with its growing adoption in fintech and IoT. The episode closes by considering whether Elixir will remain a specialist tool or break into mainstream enterprise development. No ads—listener support keeps this show independent.

Lucas and Luna dive into Apache Kafka's evolution from a LinkedIn messaging system to the de facto standard for event-driven architecture in 2026. They unpack how Kafka's log-based design handles millions of events per second at companies like Uber and Netflix, why its ecosystem has grown to include Kafka Connect and Kafka Streams, and how new tiered storage and KRaft consensus are reshaping its future. The hosts also discuss the trade-offs between Kafka and alternatives like Redpanda and Pulsar, and why event-driven architecture is now a core pattern for real-time data pipelines, microservices, and AI training data ingestion.
