Firmware for crack gauges
Geosciences Survey has developed IoT hardware that measures cracks in buildings. When flaws in the hardware were found, they were mitigated in the firmware and we helped them develop new embedded Rust firmware to replace it. We focused on reliability and power efficiency so the device would report its measurements for multiple years over LTE.
Open Device Partnership
ODP is an industry-wide, open-source initiative focused on advancing security, fundamentals, and standardization in device software. As part of this initiative, we're helping the Microsoft Surface team to develop firmware for their devices, particularly the fundamentals like a HAL, secure boot and storage.
Rocsys hands-free charging
Rocsys is the leading platform for hands-free, effortless charging solutions. We've collaborated with their team to develop crucial embedded software in Rust, sharing knowledge through pair programming sessions and code reviews and building expertise along to the way.
Charging station controller
BlueBird Power is innovating the consumer home energy system with its home charging station. They paired up with our embedded team to develop the charging control firmware that interfaces with the car. The firmware meets the time and safety-critical requirements of working with high power.
IoT tracking sensor
Dutch IoT Solutions build asset trackers. They are very low power and water resistant, with LTE Cat M1, NB-IoT and Wi-Fi connectivity. Due to its unique algorithm the tracker has a lifetime of over 5 years on the same batteries. Our joint team developed the firmware and backend services for the platform these devices run on.
Satellite firmware
Our team supported the developers at Gama Space with their on-board solar sail satellite firmware, which deploys the sail and facilitates communication to the ground station. Gama Space works on solar sailing to enable deep space exploration and chose Rust as their core technology to ensure maximal reliability of their software systems.
Web engineering
Demand Response implementation
OpenADR is a protocol for automatic demand-response in electricity grids, used, for example, for dynamic pricing or load shedding. We built Openleadr-rs, an opinionated, open-source Rust implementation of the OpenADR 3.0 protocol, for ElaadNL.
openleadr-rs is part of the OpenLEADR project, governed by the Linux Energy Foundation.
Election software
The Dutch Electoral Council is building Abacus, the new application to support the paper-based vote counting process for all Dutch election results and distribution of seats. In line with the Council's mission to ensure a fair, transparent and verifiable electoral process, the application is built in-house and open-source. Our engineers have joined the Electoral Council developer team for both frontend and backend development.
Trust Spanning Protocol
The Trust Spanning Protocol provides encrypted-and-authenticated communication between parties that use various identity providers, and can also be used to establish private identities and relationships between parties. We developed the Rust SDK for TSP together with Futurewei Technologies, based on the first draft of the Trust over IP Foundation.
Gamified learning tool
For researchers at the Donders Institute for Brain, Cognition, and Behaviour, our team developed MindSort, an educational game and a web-based language learning tool. Users can choose to share their data for neuro-linguistic research purposes.
EV communications platform
Lightyear developed a revolutionary solar-powered EV. Our Rust experts were part of the team that built Lightyear's Core Platform: the cloud-hosted platform that connects customers, vehicles, and backend systems. Our devs did engineering work as well as training of (new) team members on the job.
Digital identity verification
Our team developed the Verder Helpen platform, which allows goverments to verify the identity of citizens during digital communication, such as video calls and chat applications. The platform was created for Dutch local governments, is DigiD-compliant, and works with various wallets as well.
Systems engineering
Stabilizing Rust support for TrustZone
TrustZone is a hardware feature on Arm devices that ensures that secrets (e.g. encryption keys) are not leaked to applications. This mechanism statically rules out whole classes of security vulnerabilities.
Funded by Microsoft and Infineon, we are working towards stabilizing Rust compiler support for TrustZone.
Emergency response
Dutch emergency services (fire brigade, (air) ambulance, police, etc) depend on the P2000 paging system to respond to alarms. This system is from the 90s, making resources and bandwidth extremely limited. We worked on a new Rust implementation, including scheduling and encoding messages for the pagers, in collaboration with our client's engineers, Technolution.
Time synchronization
Running on millions of devices and servers, NTP and PTP are vital building blocks of the Internet and other critical infrastructure. Our initiative, Project Pendulum, provides memory-safe time synchronization.
Funded by Sovereign Tech Fund, Prossimo and NLnet Foundation.
Sudo and su
For the ISRG, the creators of Let's Encrypt, we implemented sudo-rs, a Rust implementation of the ubiquitous Linux 'sudo' command, critical on open-source operating systems that power the Internet.
The project is a joint effort with Ferrous Systems.
