My plans at FOSDEM: SourceHut, Hare, and Helios January 24, 2023 on Drew DeVault's blog

FOSDEM is right around the corner, and finally in person after long years of dealing with COVID. I’ll be there again this year, and I’m looking forward to it! I have four slots on the schedule (wow! Thanks for arranging these, FOSDEM team) and I’ll be talking about several projects. There is a quick lightning talk on Saturday to introduce Helios and tease a full-length talk on Sunday, a meetup for the Hare community, and a meetup for the SourceHut community. I hope to see you there!

Lightning talk: Introducing Helios

Saturday 12:00 at H.2215 (Ferrer)

Helios is a simple microkernel written in part to demonstrate the applicability of the Hare programming language to kernels. This talk briefly explains why Helios is interesting and is a teaser for a more in-depth talk in the microkernel room tomorrow.

Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level, high performance tasks. Helios uses Hare to implement a microkernel, largely inspired by seL4.

BoF: The Hare programming language

Saturday 15:00 at UB2.147

Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level, high performance tasks.

At this meeting we’ll sum up the state of affairs with Hare, our plans for the future, and encourage discussions with the community. We’ll also demonstrate a few interesting Hare projects, including Helios, a micro-kernel written in Hare, and encourage each other to work on interesting projects in the Hare community.

BoF: SourceHut meetup

Saturday 16:00 at UB2.147

SourceHut is a free software forge for developing software projects, providing git and mercurial hosting, continuous integration, mailing lists, and more. We’ll be meeting here again in 2023 to discuss the platform and its community, the completion of the GraphQL rollout and the migration to the EU, and any other topics on the minds of the attendees.

Introducing Helios

Sunday 13:00 at H.1308 (Rolin)

Helios is a simple microkernel written in part to demonstrate the applicability of the Hare programming language to kernels. This talk will introduce the design and rationale for Helios, address some details of its implementation, compare it with seL4, and elaborate on the broader plans for the system.

Disappointing phones

Since 2019, my phone has been a OnePlus 5T running LineageOS, and I've loved it.Unfortunately, it uses 3G for calls, and all New Zealand networks plan to turn off their 3G network in early 2026. I would still be able to use this phone for taking photo…

Trudging Through Nonsense

Last week Anthropic released a report on disempowerment patterns in real-world AI usage which finds that roughly one in 1,000 to one in 10,000 conversations with their LLM, Claude, fundamentally compromises the user’s beliefs, values, or actions. They not…

Binary Dependencies: Identifying the Hidden Packages We All Depend On

We need better tools for uncovering phantom binary dependencies. Not having these tools makes our global tech infrastructure less secure, and puts a strain on the Open Source maintainers we rely on.
