DrugList is an Android application for scheduling drug prescriptions. The prescription names are entered into a database, along with the time they are taken. When you exit that activity with the "Save and Exit" button, the time and date for the next medication to be taken is computed, and a system alarm is set. When that alarm fires, you see a ListView with only the drugs due at that time.
WaldScan is a PHP class which recursively scans a given directory for a list of selected file types. It has many uses for any Web page which serves files over HTTP/HTTPS, for a CLI program which does batch processing of files, or in cron jobs for caching file data for faster access.
