A high school student shut down their public-facing homelab services, including a 3-year-old Gitea instance, after a RAID 5 migration corrupted VM disk images. They decided against recovery and scaling back instead, citing the operational burden of maintaining secure internet-exposed services as a student with limited time.
A patch series from Shrikanth Hegde proposes using steal time metrics to help virtual machines voluntarily reduce CPU demands during contention. The mechanism maintains a preferred CPU set that shrinks when steal time exceeds thresholds, concentrating workloads on fewer CPUs to mitigate performance degradation from lock contention and preemption.
A developer successfully ran Doom on Linux inside TinyEmu within Docker, WASM, and Electron using pi-box, an AI agent system. The project leveraged deepseek-4.1 to overcome technical challenges with the AgentVM's persistent filesystem, framebuffer, and sound support. The achievement demonstrates the maturity of the pi-box platform and its ability to handle complex system tasks autonomously.
