  • Why OCaml Powers Financial Trading Systems in 2026

    Why OCaml Powers Financial Trading Systems in 2026
    Aug 29 2026
    Lucas and Luna explore why OCaml, a 30-year-old functional programming language, has become a quiet powerhouse in financial trading systems. From Jane Street's massive adoption to its role in high-frequency trading, they unpack the language's unique strengths: strong static typing, immutability, and a pragmatic approach that balances safety with performance. This episode dives into how OCaml's type system catches bugs before they happen, why its performance rivals C++, and how it manages the complexity of modern trading infrastructure. With a look at real-world use cases and the trade-offs that come with choosing functional programming, the hosts discuss why OCaml is gaining traction beyond finance, in areas like compilers and formal verification. If you're curious about languages that prioritize correctness without sacrificing speed, this conversation is for you. #OCaml #FunctionalProgramming #TradingSystems #JaneStreet #HighFrequencyTrading #FinancialTechnology #ProgrammingLanguages #TechPodcast #SoftwareEngineering #TypeSystems #ImmutableProgramming #PerformanceComputing #CompilerDesign #FexingoBusiness #BusinessPodcast #TechnologyPodcast #Coding #Developer Keep every episode free: buymeacoffee.com/fexingo

  • Why Vala Is the Unexpected Glue of Modern Linux Apps

    Why Vala Is the Unexpected Glue of Modern Linux Apps
    Aug 28 2026
    On this episode, Lucas and Luna take a close look at Vala, the language that has quietly been powering GNOME apps for years, and why it's seeing renewed interest in 2026. With the rise of system programming alternatives and the push for faster, more memory-safe code, Vala offers a unique middle ground: it compiles to C, integrates natively with GObject, and feels like a higher-level language. The hosts drill into a concrete example: how a modern GTK app like the new Ambitious Notes app uses Vala to cut boilerplate, and how its C-generated output keeps performance predictable. They also unpack Vala's controversial history—its ties to GNOME, its near-death moments, and the community that kept it alive. If you're curious about a language that's both pragmatic and powerful, this episode gives you a clear sense of why Vala might be worth a second look in your next Linux project. Plus, a quick note on supporting the show with a coffee. #ValaLang #GNOME #GTK #Linux #SystemProgramming #CProgramming #GObject #MemorySafe #DeveloperTools #OpenSource #ProgrammingLanguages #Technology #FexingoBusiness #BusinessPodcast #Coding #SoftwareDevelopment #TechPodcast #LinuxApps Keep every episode free: buymeacoffee.com/fexingo

  • Why Ada Is Back in Critical Systems

    Why Ada Is Back in Critical Systems
    Aug 27 2026
    In the summer of 2026, Ada—a language many programmers wrote off as a relic of the 1980s—is quietly becoming the backbone of aerospace, defense, and even autonomous rail systems. In this episode, Lucas and Luna explore how Ada's unapologetic focus on safety and correctness is making it the go-to choice for projects where a single bug could cost billions or lives. They dig into the upcoming Ada 202x standard, the rise of open-source compilers like GNAT, and the growing demand for Ada developers in Europe's defense industry. They also look at how Ada's approach to formal verification is influencing modern languages like Rust, and why the language's steep learning curve is becoming its biggest selling point. If you've ever wondered whether 'old' languages can still define the future, this episode makes the case that Ada is doing exactly that. #Ada #CriticalSystems #SafetyCritical #FormalVerification #GNAT #Avionics #DefenseIndustry #EuropeanDefense #RailwaySignaling #Ada202x #Rust #ProgrammingLanguages #SoftwareEngineering #LegacyCode #OpenSourceCompiler #TechPodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • Why Julia Is the Language of Scientific Computing in 2026

    Why Julia Is the Language of Scientific Computing in 2026
    Aug 26 2026
    In this episode, Lucas and Luna explore why Julia, the dynamic language born at MIT, has become the unexpected powerhouse in scientific computing by 2026. They dive into Julia's unique multiple dispatch system, which lets you write generic code that runs as fast as C, and how it's replacing Python in fields like climate modeling and genomics. They also discuss the recent surge in Julia's adoption among researchers and the growing ecosystem of packages, from differential equations to machine learning. With a focus on the practical, they look at a specific case: how a pharma company used Julia to slash a drug discovery simulation from days to hours. If you're curious about a language that's making scientists' lives easier, this episode is for you. #JuliaLang #ScientificComputing #ProgrammingLanguages #TechPodcast #MultipleDispatch #MIT #DrugDiscovery #ClimateModeling #HighPerformanceComputing #OpenSource #DeveloperTools #TechTrends #FexingoBusiness #BusinessPodcast #Technology #Coding #DataScience #Research Keep every episode free: buymeacoffee.com/fexingo

  • Why Janet Is the Surprising Language of 2026

    Why Janet Is the Surprising Language of 2026
    Aug 25 2026
    In this episode, Lucas and Luna explore Janet, the Lisp-like language that's quietly becoming a favorite for scripting, systems, and AI glue code. They discuss its minimalist core, its powerful macro system, its built-in support for parallel processing and networking, and why it's gaining traction among developers who want the expressiveness of Lisp without the parentheses baggage. With concrete examples and a look at its growing ecosystem, they make a case for why Janet deserves a spot in every developer's toolkit. Plus, they explain why its small footprint and fast startup make it ideal for embedded and edge applications. If you've ever wondered about the future of programming languages beyond the mainstream, this episode is for you. #JanetLang #LispDialects #FunctionalProgramming #ScriptingLanguage #SystemsProgramming #AIProgramming #DeveloperTools #TechPodcast #ProgrammingLanguages #CodeCraft #FexingoBusiness #BusinessPodcast #FexingoTechnology #ModernCoding #OpenSource #EmbeddedSystems #EdgeComputing #LanguageDesign Keep every episode free: buymeacoffee.com/fexingo
