The \"why\"\ncompanion to [ops](https://github.com/piotraf/ops) (the \"what\").\n\nEach note answers a specific question I had, fixed something I broke, or\ncaptures a non-obvious gotcha worth remembering. Style is concise and\npeer-to-peer — not tutorials.\n\n## Layout\n\n| Path | Scope |\n|---|---|\n| [db/mysql](db/mysql/) | MySQL — upgrades, recovery, tuning, Connector/J |\n| [db/mariadb](db/mariadb/) | MariaDB-specific notes |\n| [db/firebird](db/firebird/) | Firebird 3.x/4.x admin |\n| [db/oracle](db/oracle/) | Oracle DB admin |\n| [db/postgresql](db/postgresql/) | PostgreSQL admin |\n| [linux/gentoo](linux/gentoo/) | Portage, USE flags, profile-specific issues |\n| [linux/oracle-linux](linux/oracle-linux/) | OL 7/8/9/10 specifics |\n| [linux/opensuse](linux/opensuse/) | openSUSE Leap \u0026 SLES |\n| [linux/debian-ubuntu](linux/debian-ubuntu/) | Debian/Ubuntu specifics |\n| [net](net/) | Networking — VLANs, switching, OPNsense, SFP/DAC |\n| [virt](virt/) | Proxmox, VirtualBox, LXC, KVM |\n| [homelab](homelab/) | Office lab — naming, topology, sanitized diagrams |\n\n## Conventions\n\n- One Markdown file per topic. Use descriptive filenames\n  (`charset-conversion.md`, not `notes-2.md`).\n- Cross-link freely between notes using relative paths.\n- Link companion scripts in [ops](https://github.com/piotraf/ops) when\n  prose explains code that lives over there.\n- Date-stamp version-sensitive observations (`# Verified 2026-04-28`) so\n  readers can judge staleness.\n\n## Status\n\nPersonal notes published publicly. Accuracy reflects my best understanding\nat the time of writing. Not a substitute for vendor documentation.\n\n## License\n\n[CC BY 4.0](LICENSE) — credit appreciated, derivatives welcome.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpiotraf%2Fkb","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpiotraf%2Fkb","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpiotraf%2Fkb/lists"}
