# kb — knowledge base

Public notes on Linux, databases, networking, and infrastructure. The "why"

companion to [ops](https://github.com/piotraf/ops) (the "what").

Each note answers a specific question I had, fixed something I broke, or

captures a non-obvious gotcha worth remembering. Style is concise and

peer-to-peer — not tutorials.

## Layout

| Path | Scope |

|---|---|

| [db/mysql](db/mysql/) | MySQL — upgrades, recovery, tuning, Connector/J |

| [db/mariadb](db/mariadb/) | MariaDB-specific notes |

| [db/firebird](db/firebird/) | Firebird 3.x/4.x admin |

| [db/oracle](db/oracle/) | Oracle DB admin |

| [db/postgresql](db/postgresql/) | PostgreSQL admin |

| [linux/gentoo](linux/gentoo/) | Portage, USE flags, profile-specific issues |

| [linux/oracle-linux](linux/oracle-linux/) | OL 7/8/9/10 specifics |

| [linux/opensuse](linux/opensuse/) | openSUSE Leap & SLES |

| [linux/debian-ubuntu](linux/debian-ubuntu/) | Debian/Ubuntu specifics |

| [net](net/) | Networking — VLANs, switching, OPNsense, SFP/DAC |

| [virt](virt/) | Proxmox, VirtualBox, LXC, KVM |

| [homelab](homelab/) | Office lab — naming, topology, sanitized diagrams |

## Conventions

- One Markdown file per topic. Use descriptive filenames

  (`charset-conversion.md`, not `notes-2.md`).

- Cross-link freely between notes using relative paths.

- Link companion scripts in [ops](https://github.com/piotraf/ops) when

  prose explains code that lives over there.

- Date-stamp version-sensitive observations (`# Verified 2026-04-28`) so

  readers can judge staleness.

## Status

Personal notes published publicly. Accuracy reflects my best understanding

at the time of writing. Not a substitute for vendor documentation.
