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

Lucas and Luna dive into Svelte's rising developer satisfaction scores and its unique compile-time approach that eliminates the virtual DOM. They examine how Svelte 5's runes syntax is reshaping reactive state management, and why companies like Apple, Spotify, and The New York Times have adopted it for certain projects. With specific benchmarks showing 2x faster initial render times compared to React, this episode explores whether Svelte's leaner architecture is the key to solving frontend bloat. The hosts also discuss the trade-offs: a smaller ecosystem, fewer job listings, and the learning curve for traditional React developers. Ultimately, they look at what Svelte's growth says about the industry's hunger for simplicity and performance in 2026.

Lucas and Luna dive into TypeScript's explosive growth in 2026. With over 60% of JavaScript developers now using TypeScript in production, and major frameworks like React, Vue, and Svelte shipping first-class TypeScript support, the language has become the de facto standard for large-scale web development. They explore why TypeScript's gradual typing, rich IDE support, and ecosystem maturity have made it a must-learn for front-end and back-end developers alike, and discuss the controversial rise of 'TypeScript-Only' frameworks like Deno and Bun. This episode covers the numbers, the tooling revolution, and what it means for developers sticking with plain JavaScript.

This episode explores why Lua remains a dominant scripting language in gaming and embedded systems in 2026. Lucas and Luna dive into Lua's lightweight design, its role in game engines like Roblox and World of Warcraft, and its surprising use in IoT devices. They discuss LuaJIT's performance advantages, the trade-offs between Lua and Python for embedded scripting, and why Lua's simplicity makes it a favorite for modding communities. The conversation also touches on Lua's adoption in Redis and Nginx for extending functionality. A concrete example: how a small team at a smart-home startup used Lua to script device behavior with minimal memory footprint. No fluff, just the story of a language that quietly runs a huge chunk of the digital world.

Episode 108 of The Programming Languages Podcast dives into Haskell's role in the financial industry. Lucas and Luna explore how banks and trading firms use Haskell for high-stakes systems that demand correctness and reliability. They discuss Jane Street's trading infrastructure, the use of Haskell in smart contracts for blockchain, and why functional programming reduces bugs in critical code. The episode also covers the practical challenges of adopting Haskell, including hiring and ecosystem maturity. With real-world examples and concrete numbers, this is a look at a language that thrives where failure is not an option.

When we think of modern programming, Fortran doesn't come to mind. But in 2026, Fortran remains a cornerstone of high-performance computing, especially in weather simulation, physics modeling, and scientific research. Lucas and Luna dive into why Fortran persists: its unmatched array syntax, decades of optimized libraries, and the sheer cost of rewriting validated code. They discuss real examples like the ECMWF weather model and the U.S. National Weather Service, where Fortran code from the 1970s still runs in production. They also cover modernization efforts like Fortran 2018 and Coarray Fortran for parallel computing. If you think Fortran is dead, this episode will change your mind.

Episode 106 explores how Erlang and the OTP framework continue to underpin the world's most reliable telecommunication systems. Lucas and Luna break down the actor model, hot code swapping, and the 'let it crash' philosophy, using Ericsson's AXD301 as a concrete case study. They discuss why modern cloud-native platforms like WhatsApp still lean on Erlang's decades-old design for fault tolerance, and what the rise of Elixir means for the ecosystem. A deep dive into the language that delivers nine nines of reliability.

Most developers have heard of Rust. Fewer have heard of Zig. Lucas and Luna explore why Zig—a small, unassuming systems language without a garbage collector or a borrow checker—is quietly gaining traction in performance-critical niches like game engines, embedded firmware, and build tooling. They walk through a concrete example: a game studio that dropped its custom C++ build system for Zig's comptime and cross-compilation features, cutting compile times by 40 percent and halving their CI pipeline. Lucas explains how Zig's manual memory management model appeals to developers who find Rust's borrow checker too restrictive yet want more safety than raw C. Luna pushes back on Zig's lack of a mature standard library and package manager. The episode closes with the question: will Zig remain a specialist tool or evolve into a broader contender?

SQLite is everywhere—in your phone, browser, and car—yet it rarely gets the spotlight. In this episode of The Programming Languages Podcast, Lucas and Luna explore why SQLite's zero-configuration, serverless design makes it the world's most deployed database engine. They dive into its unique architecture: a single-file database that uses B-tree storage and a carefully designed locking protocol to handle concurrency without a separate server process. Lucas explains how SQLite's atomic commit and rollback work via a journal file, and why its decision to eschew client-server networking makes it incredibly reliable for embedded systems. They also discuss the surprising scale—SQLite can handle terabytes of data and hundreds of concurrent readers—and its role in mobile apps, aviation software, and even space probes like NASA's Mars rovers. The episode addresses common criticisms, like limited write concurrency, and clarifies where SQLite shines versus PostgreSQL or MySQL. Listeners will walk away understanding why SQLite is the unsung hero of modern data management.

Lucas and Luna break down the SAFE note—the Simple Agreement for Future Equity—and why it has become the go-to instrument for early-stage startup funding in 2026. They walk through a real case: a $2.5 million seed round for a fintech startup using a SAFE with a $15 million valuation cap and no discount. Lucas explains the mechanics, the recent SEC rule changes that made SAFEs more standardized, and how they compare to convertible notes. Luna probes the risks for founders and the common negotiation pitfalls around valuation caps and most-favored-nation clauses. They also touch on how the SAFE's simplicity reduced legal costs for seed rounds from $50,000 to under $10,000. By the end, listeners will understand exactly how a SAFE works, when to use one, and what to watch out for.

Lucas and Luna dive into WebAssembly (Wasm) as it hits a critical inflection point in mid-2026. They explore how Wasm is moving beyond the browser into server-side runtimes, edge computing, and plugin systems—with concrete examples like Figma's use of Wasm for Photoshop-level performance in the browser and Docker's integration of Wasm modules. They break down the 2025 Wasm GC spec adoption, the rise of the Component Model, and why companies like Fastly and Cloudflare are betting on Wasm for serverless. The conversation also touches on the 'Wasm vs. container' debate, and whether Wasm can dethrone JavaScript as the universal runtime. No hype—just the numbers and the real use cases.
