An air gap means no network path at all, and a rented VPS cannot give you one. Build egress-denied inference instead: default-deny outbound, staged weights.
Fix SearXNG engine timeouts and KeyError
Read the SearXNG service log and /stats to tell a timeout from a suspended engine or a crash like KeyError, then fix each one in settings.yml.
What does an AI server cost to build?
The accelerator sets most of the bill. Learn how VRAM, memory bandwidth, power headroom, cooling and your own tariff decide what the rest costs.
Docker Compose TZ: fix container time
Set TZ in a Compose service, find valid zone names with timedatectl, and understand why container logs show UTC while the host clock is right.
Ansible reboot: only when the server needs it
Gate the reboot on evidence the host reports: the Ubuntu marker file, the Red Hat exit code, then reboot in slices so the whole fleet stays up.
Where Immich in Docker stores your photos
Immich splits originals, thumbnails, transcodes and the Postgres database across two host paths. Learn which folders are the only copy and how to move them.

Add a Jellyfin service to an existing arr stack compose file: matching PUID and PGID, one media mount at the same path, and a port bound to localhost.
Run just one service with Docker Compose
Update one container in a multi-service stack: docker compose up -d web, why depends_on still starts, --no-deps, start vs up, stop, and --scale.
Connect Prowlarr, Sonarr and qBittorrent
Wire your arr stack together: indexers in Prowlarr, API keys into Sonarr and Radarr, then qBittorrent as the download client by container name.
Webmin default login and password reset
Webmin ships no default username or password. The login is a system account. Reset a forgotten password or clear a blocked host from the shell.
Add a WireGuard peer without restarting the VPN
Add a new WireGuard client with wg syncconf and wg-quick strip so connected peers stay up, plus wg set, wg-quick save, AllowedIPs collisions and PostUp rules.

FTP uses TCP 21 plus a separate data channel, FTPS adds TLS, SFTP rides SSH on port 22. Which ports to open, and why plain FTP leaks your password.
Docker Compose vs Kubernetes: which one?
Compose runs a multi-container app on one host. Kubernetes schedules across machines. Which one your VPS needs, and the four things only a cluster buys.
Pipe output to two commands with tee
A pipe has one reader, so feeding two commands needs tee. Copy a stream to a file, append with tee -a, fan out with process substitution, and read PIPESTATUS.
Stream a directory over SSH with tar
Copy a directory to another server with tar and SSH: why -f - is needed, where -C goes, who owns the extracted files, and compression in the pipe.

Pair a storage VPS with your main VPS
Run the app on a fast small VPS and keep the terabytes on a cheap storage VPS. Join them with NFS, SSHFS or rclone over WireGuard, and survive a lost mount.
An open model instead of a Claude plan
What the Claude plans cost, then the honest part: which open-weight model on a VPS you run yourself covers coding, long documents or drafting.
Claude Pro in Brazil: what you actually pay
