Open Source

Een selectie van eigen initiatieven en onze bijdrages aan open source projecten

Open source software is een cruciaal deel van al onze techniek, van web app tot embedded software. Door de jaren heen verandert onze software stack; de open source basis blijft. Waar we kunnen dragen we ons steentje bij om de open source community nog sterker te maken.


Statime is an initiative of Tweede golf, a work-in-progress implementation of the Precision Time Protocol (PTP) in Rust.

High-precision timing is part of crucial networking infrastructure. With Statime we aim to provide a memory-safe alternative for existing implementations.

The first milestones of the project were kindly co-funded by the NLnet Foundation.


An embedded-nal implementation for the nRF9160 (built on top of the nrfxlib rust crate).

Other than exposing the NAL, it also implements enabling and disabling the modem when required automatically.



A set of rust crates for making stack dumps and getting stack traces out of them.

Developed and maintained by Dion.


Developed by Ruben, RP1 is a procedural macro that generates a set of useful basic CRUD (Create-Read-Update-Delete) endpoints in a REST-like API with JSON output.

Check out the blog post RP1: an experimental Diesel-based CRUD for Rocket, for more.


Rust library for interfacing with IRMA servers.

IRMA is a set of free and open-source software projects implementing the Idemix attribute-based credential scheme, created by the Privacy by Design Foundation.

It allows users to safely and securely authenticate themselves as privacy-preserving as the situation permits.


TGuard is a web-based sending and decrypting service for irmaseal-encrypted messages that is currently in development at Tweede Golf.

TGuard utilizes IRMA to allow a user to encrypt messages client-side. These messages can be decrypted client-side once the receiver proves to be the owner of attributes the message was encrypted for, like an e-mail address, name, or an identifying number.


For ID Contact we researched the possibilities of digital identification: how can residents organize their personal government affairs in a simpler and more reliable way? By telephone, via chat or via a video call.

The ID Contact innovation pilot is a collaboration between the municipalities of Arnhem, Nijmegen and the Drechtsteden and knowledge partners such as the Tax Authorities and iHub (Radboud University).

Within the ID Contact team we developed the software that makes secure digital identification possible.


Driver crate for the Texas Instruments ADS1292 24-bit 2-channel low-power analog front end for ECG applications.


Cloud storage abstraction for Node.js

Developed by Daniel, storage-abstraction provides an abstraction layer for interacting with a storage; this storage can be a local file system or a cloud storage. Currently local disk storage, Backblaze B2, Google Cloud and Amazon S3 and compliant cloud services are supported.

Also see the related blog post, Cloud storage simplification and abstraction for Node.js or give the npm package a try.
