Linux tools, in detail.
Commands, requirements and status.
THE TOOLS / FIVE INSTRUMENTS
Commands, technical scope, repositories and current status. Each tool has its own page with examples and validation limits.
Linux observability, straight from the kernel.
perf_event_open, eBPF, procfs, sysfs and netlink — no perf, bpftrace or bcc underneath. Every number says what it lost, how it was obtained and how far it can be trusted.
omn top -- ./your-program
9 families · tested on 17 distro images + 5 variants, arm64 and containers · MIT / Apache-2.0
A Linux companion for the terminal.
Short answers first, your machine’s real state second, the deep “why” only if you want it. Never runs your commands, never changes the system, never touches the network.
atfq free --why
x86_64 + aarch64 binaries · MIT / Apache-2.0
Check that your program holds on every distro.
Boots VMs on the real kernel of each target distro, runs your program there, and compares failing targets with passing ones using environment facts — libc, BTF, perf policy, lockdown and memlock limits.
distroproof run --target rocky-8 -- envprobe --json
20 distro images · Omniscient case study: 27 defects found · MIT / Apache-2.0
Package inventory, provenance and conservative plans.
Lists what is installed and why, explains dependencies, and reconciles packages and dotfiles against a declarative TOML profile — through a plan you can read, save and dry-run first.
xpac plan -f system.toml
seven native executors · signed release binaries · MIT / Apache-2.0
Reproducible environments on your own Proxmox homelab.
Define an environment once, provision it on Proxmox, then manage and reach it from desktop or mobile. A native client and a self-hosted control plane.
native/API workflows tested · real homelab acceptance pending · MIT / Apache-2.0
FROM QUESTION TO MACHINE / FIVE ROLES
Each tool can be used on its own. Explore the roles and the implementation details behind them.
