About
Folkert
- Systems software engineer
- folkert@tweedegolf.com
Folkert is an expert in systems programming. He has made major contributions to the creation of the (soon-to-be) friendly, fast, functional language called Roc
- in fact, he has so far written about half of the code; He co-teaches (and co-creates) the university course Rust 101
; And he is working on the Rust implementation of the Network Time Protocol, ntpd-rs
.
Difficult problems don´t rattle him. In fact, we can rely on Folkert to face them head-on and produce solid implementations in remarkably little time.
In his spare time, Folkert often continues to work on languages (natural or other) and he likes to cook or spend time in the garden.

Open-source work
ntpd-rs
ntpd-rs is an open-source implementation of the Network Time Protocol completely written in Rust, with a focus on exposing a minimal attack surface. This video explains how ntpd-rs brings NTP into the modern era.
The project was initially funded by ISRG's Prossimo, as part of their mission to achieve memory safety for the Internet's most critical infrastructure. The NTP initiative page on Prossimo's website tells the story.
ntpd-rs is part of Project Pendulum. In July of 2023 the Sovereign Tech Fund invested in Pendulum, securing development and maintenance in 2023, and maintenance and adoption work in 2024.
