Chaospott, the Chaos Computer Club community in Essen, hosts its monthly Digital Independence Day at its hackerspace on Sibyllastraße 9. Over coffee and cake, members offer advice on all questions around getting out of the surveillance nightmare that is today's mainstream IT service landscape. Anyone who wants to set something up on the spot should bring a laptop or smartphone along with a charging cable. The open session runs from 16:00 to 18:00 and no registration is required. It is part of the nationwide DI.day initiative, which invites people to switch to privacy-respecting alternatives on the first Sunday of every month.

Identity Fabric Impact Day is a focused, one-day, in-person event taking place on September 9, 2026, bringing together IAM professionals, security leaders, architects, and solution providers to explore modern Identity Fabric architectures.

MetaRheinMain ChaosDays 2026, under the motto "Grenzen überwinden". Annual Chaos Computer Club conference held since 2004 by MRMCD e.V. with local hackerspaces and universities, covering IT security and privacy, digital sovereignty and open technologies, network policy and surveillance, plus hardware, software and protocol hacking.

A small hack and "frickel" festival on the Flensburg Fjord at Strandpavillon Solitüde, organised by Chaos Computer Club Flensburg e.V. Open to anyone interested in tinkering, programming, hacking, soldering, 3D printing and net politics, with no prior expertise required. Soldering and 3D-print stations run throughout the weekend.
Oxidize is the conference for companies and developers using Rust professionally, held at Tagungswerk in Berlin across three days: one workshop day followed by two days of talks. The workshop day covers safety-critical development with Ferrocene, making Rust and C++ get along, integrating Rust into existing embedded C applications, and embedded Rust with batteries included. The talk programme is drawn from teams shipping Rust in production — Volvo Cars on its next-generation EV battery, Quantum Systems on unmanned systems, plus Vector, JetBrains and Woven by Toyota — alongside sessions on bare-metal ESP32, Embassy, shipping native libraries, vendor drivers and high-assurance projects. Panels cover the Rust job market and the practicalities of executing safety-critical work in Rust.

Xen Summit is the annual gathering of the Xen Project community, and the 2026 edition runs for three days at the HEADS office in Aschheim, just east of Munich, hosted by Renesas. Two days of technical talks are followed by a third day given over entirely to design sessions, which are working sessions where contributors settle architecture, implementation plans and project direction face to face rather than sit through presentations. The published programme leans heavily on embedded and automotive virtualization, with talks on Xen on Renesas R-Car Gen5 silicon, mixed-criticality workloads, thermal management and the path toward safety certification, alongside a cloud and infrastructure track covering XCP-ng, XenServer nested virtualization and per-guest resource management. Other sessions cover Xen on RISC-V, Arm VHE-always hardware, formal methods, secure inter-domain communication over Argo, and compliance work against DO-178C and IEC 62443. The audience is Xen developers and maintainers, embedded and automotive engineers, cloud and infrastructure practitioners, researchers and students. The summit is hybrid, with standard in-person registration at $200 and a $20 rate for academics and for virtual attendance, plus a community social dinner on the evening of 16 September.
