Finally, an actually interactive workshop, but this one was also with my mentoring, as the speakers are no less than our [GSoC](#google-summer-of-code-2024) team for [deploying OSS Fuzz on the OpenPrinting repositories](https://github.com/OpenPrinting/fuzzing/wiki/Integrating-C%E2%80%90based-OpenPrinting-Projects-in-OSS%E2%80%90Fuzz-Testing-(GSoC-2024)), contributor Jiongchi Yu and mentors George-Andrei Iosif and Dongge Liu. Unfortunately Jiongchi could not come to the Summit in-person as he was on another conference in the US. So after a short introduction by me, George Andrei and Donggi were explaining the steps for the attendees to do on their laptops, with the Heartbleed on OpenSSL being the example. Jiongchi was connected via video meeting and in the end he told about the OSS Fuzz deployment on OpenPrinting.

In this talk Cristovão Cordeiro, manager of a containerization team at Canonical, tells about freeing containers from unnecessary files, not only to save storage space but also to reduce the attack surface of the containerized applications. He uses the `chisel` tool which allows the installation of parts of Debian packages (so-called "slices"). Cristovão was also [GSoC](#google-summer-of-code-2024) mentor at OpenPrinting this year for the [project of Rudra Pratap Singh, to create OCI container images of CUPS and Printer Applications](https://medium.com/@rudransh.iitm/gsoc-2024-final-report-container-chronicles-759fe7f23ac6).

Right after Cristovão's talk one could get hands-on with his subject matter in this workshop. And it was really interactive. On one of the first slides there are instructions on which packages to install and a link to a GitHub repo with all the example files for the exercises in a subdirectory for each task. I have actually done the exercises during the workshop and they all worked as designed.

And with Deep Computing having presented their RISC V mainboard for Framework, it is exactly this which makes it into the sample laptop within the 5 minutes of a lightning talk slot. Unfortunately no boot test is demonstrated ... But the demo was already impressive this way.
