Apache NuttX is a real-time operating system (RTOS) built around standards compliance. Because it’s POSIX compliant, code moves easily between a Linux development environment and an embedded runtime. Recorded at Community Over Code in Glasgow, this conversation with Alin Jerpelea (NuttX PMC Chair, Sony) covers why NuttX feels familiar to Linux kernel developers, how a volunteer community supports 15 architectures and more than 400 boards, and why the hackathon is porting Doom from the Raspberry Pi 4 down to Sony Spresense microcontrollers. We also talk about how the PMC stays vendor-neutral with Sony, Xiaomi, and Espressif all involved, where the project is headed after nearly 20 years (including small-footprint machine learning for IoT), and its policy on AI-assisted contributions: they’re welcome as long as they’re marked, but purely machine-generated code is rejected.

Apache BuildStream is a software integration tool that orchestrates the building of entire Linux operating systems from source — assembling hundreds of components, each with its own build system and programming language, into reproducible outputs. Sam Thursfield from Codethink joins the show to explain how BuildStream differs from tools like Bazel, Nix, and traditional distro package managers, how it grew out of an R&D project to become the build engine behind GNOME OS and the Freedesktop SDK Flatpak runtime, and why the project chose the Apache Software Foundation as its long-term home. We also talk about the relationship with BuildGrid, the Bloomberg connection, the plugin architecture that keeps the core stable, and where new contributors can get involved.
Apache Polaris is the open source metadata catalog for the data lakehouse — a vendor-neutral implementation of the Iceberg REST Catalog spec. In this episode, Rich Bowen speaks with PMC members Jean-Baptiste Onofré (Dremio) and Yufei Gu (Snowflake) about how two competing companies came together under Apache governance to build a shared standard, the project’s extraordinary release velocity since graduating as a TLP in February 2026, and where the roadmap is headed — including multi-format support, AI use cases, and fine-grained access control.
Rich Bowen speaks with Jinwoo Hwang about Apache Geode, the distributed in-memory data management platform that delivers low-latency, scalable data access for high-performance applications. In a rare story of open source revival, Jinwoo describes how Geode — originally born as GemFire in 2002 and donated to the ASF in 2015 — declined into inactivity by 2023 and was voted for retirement, only to be brought back to life with a major 2.0 release in December 2025. They discuss the massive modernization effort required (Java 21, Spring Framework 6, Jakarta EE), the personal cost of that work, and what’s next for the project’s security and stability roadmap.
Tim Saucer, PMC member and primary maintainer of Apache DataFusion’s Python bindings, joins PlusOne to talk about how he went from frustrated Spark user to open source maintainer — and how the project is using LLM-powered “skills” to keep its Python API in full parity with the upstream Rust library. He walks through the three developer-facing skills they’ve built (expose new APIs, make them Pythonic, audit the user-facing docs) and shares practical advice for other projects looking to adopt a similar approach: treat your skills like test-driven software, constrain the agent to one shot, and use your existing examples as the ground truth.
Andrew Lamb, PMC Chair of Apache DataFusion, explains how this open source query engine lets teams build specialized analytic databases without reinventing SQL from scratch. We cover how DataFusion grew out of Apache Arrow, why it split into its own top-level project, how it attracted nearly 1,000 contributors, and what the rise of AI coding agents means for an embeddable database engine. If you’ve ever wondered what sits under the hood of the modern data stack — and how open source communities form around infrastructure no end user ever sees — this is the conversation.
In the March board meeting, the Apache Software Foundation seated a new board of directors, which included three new members. Emmanuel Lecharny has been around the ASF for a long time, but this is his first term on the board. He discusses some of his backstory, and his priorities for this board term.
In the March board meeting, the Apache Software Foundation seated a new board of directors, which included three new members. One of them, Chris Dutz, had served a few terms before. In this interview, he talks about his priorities for the coming year on the board.
