- I'm Roland Conybeare, a software developer engaged in continuous learning.
- Several decades of experience in the financial industry, working mostly in c++
- Trying to solve problems so that they "stay solved" -- easier said than done!
- Developer productivity. Member of the church of emacs. Trying to write better documentation.
- Numerical programming. Kalman filters, PDE solvers, stochastic processes etc.
- 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.
