2021-08-12 | ripple/nix: initialize nixpkgs pin | V | |
We're using an unstable branch over releases, as biannual package updates are too infrequent for tools with short release cycles. We're specifically using nixos-unstable, as this has more thorough testing than nixpkgs-unstable does (at the cost of lagging behind, slightly).

2021-05-26 | ripple/driver.pl: a basic syscall tracing driver | edef | |
This program spawns a child in a new cgroup (using systemd-run) under bpftrace and counts syscall invocations for each (syscall, comm) pair. It outputs a TSV of (syscall, comm, count) tuples to STDERR. This makes it easy to assess which system calls a build process uses, segmented by a useful approximation of the invoking programs.
