Have millions of trajectory files generated by AI agents? Want to manage them with git, but Git slows (e.g., a 1-hour git status)?

I built TrajFS that makes AI-agent trajectory files gittable.

Faster for Git. Friendly to agents. Still files for humans.

@tianyin_xu How tunable can an operating system be?
Today’s OSes encode performance decisions as fixed constants—macros, literals chosen at compile time. These constants cannot be changed in-situ, though their optimal values depend on workload behavior and underlying hardware conditions.

Excited to share our #OSDI2026 paper (July 13,2 PM): Xkernel: Principled Performance Tunability of Operating System Kernels. See you at OSDI!

Xkernel enables safe, programmable, millisecond-scale tuning of Linux kernel constants—no recompilation or reboot—with up to 50× speedup.
