用 Opus 5.5 拍 boat.dev 快照系统讲解片
作者与 Opus 合作，用 Blender、ffmpeg 和无头 Chrome 在 boat VM 集群上并行渲染，做了一支讲解 VM 文件系统快照能力的视频。
when you run agents for long inside sandboxes, it sucks if it stops or crashes and you lose your work! so we fixed that I believe http://boat.dev now has the most robust filesystem snapshot system out there: - snapshots include all files, installs, rights, users, browser sessions & in-VM docker state - they happen constantly, no need to request, literally can't forget to do them - you can fork a VM while it's still running - you can bake a VM image this way that you can reuse later for all your tasks or sub-users - free latest snapshots per VM: the snapshot sizes are super small, therefore cost is low. + you don't have to pay to keep them up - 2x backup in 2 EU countries for extra safety - diff-based, incremental, never saturates you or us, always space & resources efficient, minimum failure risk - even works seamlessly with DBs (even if in a Docker container) that you're running inside the VMs - lazily restored behind FUSE for fast resumes/fork, files are instantly usable but might initially load slowly, then disk becomes local nvme speed again - still not the fastest thing ever possible but we're improving every week opus and I made an explainer video, using blender + ffmpeg + headless chrome, all rendering scenes in parallel across a fleet of boat VMs:
