Ariel OS is a library operating system for secure, memory-safe, low-power Internet of Things, written in #RustLang.

We have published our first releases, but are constantly working toward more featurer, following our vision. Stay tuned.

During #FOSDEM, some of us bought a CDC Badge (https://github.com/riatlabs/cdc-badge) at the @fossasia booth.
The same day, @nils ported Ariel OS there – this might easily become the first e-paper kit we can support.

… and it was a success: We implemented runtime updates over #CoAP, and with our stack's access control, restricting changes to the VM code to authorized users is just a matter of four lines of config.

The Ariel OS project will be present at #EuroRust: Come talk with Nils and Antoine about anything related to #embedded development, be it Bluetooth LE, sensor integration or tiny WebAssembly containers.

#EuroRust25 #RustLang

The @RIOT_OS summit starts tomorrow in Dresden. Many presentations will be just as relevant to Ariel as they are to RIOT – including those given by Ariel OS contributors. More fun with embedded systems!

We're starting into day 2 of #FrOSCon together with our friends at the @RIOT_OS booth.
Work on Ariel is not just following the roadmap, it's also people playing around and trying new things. Here, Nils got Ariel to run on a calculator, and show graphics.
At the #IEEE DCOSS-IoT conference <https://dcoss.org/>, we present Ariel OS to the scientific community. Slides at <https://emmanuelbaccelli.com/Ariel-OS-DCOSS-2025.pdf>, pre-print at <https://arxiv.org/abs/2504.19662>.
