• Performance oriented programming. For example low-latency schedulers, some lockfree algos.
• Integration with REPL tools. Author of various scheme-based DSLs, more recently working with pybind11.

• XO: a set of cooperating c++ libraries, with python bindings, for simuation and complex event processing.
• cmake-examples: progressive series of cmake examples, starting from hello world.
