In the future I want to learn to stop writing my projects from scratch and start learning how to confidently host and contribute to existing projects. However, as of now I'm hosting: On a VPS: - Personal websites (career and hobbies, built on a custom PHP framework) - Websites for groups/friends (communities, file sharing, built on a custom PHP framework) - HAM radio contact log (Web based map and historical logging, built on a custom PHP framework) - Game engine projects and demos (built on a custom JS game engine) Isolated on my LAN: - Network of pi's with webcams doing motion detection (using Motion + custom shell scripts + rsync) - A server to view those pi feeds on (nginx + custom site on custom PHP framework) - NAS - Small "media center" (tried a custom site, now kodi) On a different VPS: - Minecraft server - A web server to view the world map (nginx) Some things I'd like to add in the future: - Google docs/drive alternative - (Or otherwise) a shared recipes/shopping/photosharing to use between me, my gf, and/or my family - DDG/Google/Bing search alternative - Network ad blocker - Firewall - Public transit schedule/map display for my commute - A safe way view some of my LAN-based tools remotely I'm also interested in learning the best practices for data storage/backup/recovery. Taking my data out of the hands of other providers has made me increasingly worried about hardware or software issues losing my files.
