I describe adding outdoor temperature readings to my homelab server temperature logs to account for ambient temperature changes, using OpenWeather’s free API. A bash script on a VPS polls the weather endpoint every five minutes, extracts the temperature and timestamp with awk and cut, and serves the result as a text file that each server fetches during its logging cycle; the server-side script also loads the drivetemp kernel module to read SSD temperatures. Graphs of 24 hours of data show how ambient temperature, workload, and a CPU stress test affected the three servers...
After migrating a media library from an external USB drive to a NAS and reorganising it, I needed a way to verify no files were missed in the move. I walk through building a Linux command-line pipeline using find, grep with regex, and cut to recursively list media files while filtering out directories, metadata, and unwanted filenames.
