#systemsprogramming — Public Fediverse posts

Most C++ codebases aren't getting rewritten in Rust - but that doesn't mean the two can't work together.

At Oxidize 2026, @nicofee and Nicolas Qiu Guichard (@kdab) run a practical workshop on Rust/C++ interop using CXX: calling Rust from C++ and vice versa, integrating a Rust library into a CMake project, and pulling a C++ library into a Cargo build.

Specs drift. Handwritten code doesn't keep up. What if JSON, INI Mermaid diagrams, and Markdown were your source of truth - and Rust macros handled the rest?

Tao Liu demonstrates exactly that: a workflow where structured, human-readable documents are transformed at compile time into strongly typed Rust code, applied to a working RISC-V assembler and linker.

📣 Florian Gilcher joined 𝘉𝘌𝘈𝘔 𝘛𝘩𝘦𝘳𝘦, 𝘋𝘰𝘯𝘦 𝘛𝘩𝘢𝘵 co-hosts and Elixir engineer Leandro Pereira to discuss when #Rust is the right fit in modern system architectures, especially where performance and safety are critical.

This episode explores when to stay on the #BEAM, when to reach for Rust, and how combining the two can enable powerful hybrid architectures.

Just discovered a minimal async executor for Rust 🦀

🌀 **pollster** — Block a thread until a future completes.

💯 No dependencies, ~100 lines, just `.block_on()` and done
