Episode notes
Plan For Valve Hardware Delays
- Expect Valve's new hardware to ship later than initially stated; plan purchases around mid-year timelines.
- Consider whether a bare-bones Steam machine (no RAM/storage) would suit you if it ships sooner.
VirtualBox Embraces KVM Backend
- VirtualBox is adding an option to use KVM as a native backend on Linux, reducing reliance on vendor kernel modules.
- This shifts trust toward upstream kernel virtualization and could make VirtualBox a KVM frontend over time.
BcacheFS Gains Better Tooling And Erasure Plans
- BcacheFS is maturing with user tools like a TUI monitor and upcoming erasure coding support.
- The project remains experimental but has improved enough for some to run it in production with caution.
