You threw together a network streamer to continuously +# loop through the files and launched it in a tmux (or screen) session, giving +# it a directory tree of files to play. During the day, you connected an audio +# player to the stream, listening through the workday, closing it when done. +# +# For weeks you connect to the stream daily, slowly noticing a gradual drift of +# the media. After several weeks, you take vacation. When you return, you are +# pleasantly surprised to find the streamer still running. Before connecting, +# however, if you consider the puzzle of determining which track is playing. +# +# After looking at a few modules to read info regarding the media, a quick bit +# of coding gave you a file list. The file list is in a simple CSV format, each +# line containing two fields: the first the number of milliseconds in length, +# the latter the media's title (this example is of several episodes available +# from the MercuryTheatre.info): +# +# 1709363,"Les Miserables Episode 1: The Bishop (broadcast date: 1937-07-23)" +# 1723781,"Les Miserables Episode 2: Javert (broadcast date: 1937-07-30)" +# 1723781,"Les Miserables Episode 3: The Trial (broadcast date: 1937-08-06)" +# 1678356,"Les Miserables Episode 4: Cosette (broadcast date: 1937-08-13)" +# 1646043,"Les Miserables Episode 5: The Grave (broadcast date: 1937-08-20)" +# 1714640,"Les Miserables Episode 6: The Barricade (broadcast date: 1937-08-27)" +# 1714640,"Les Miserables Episode 7: Conclusion (broadcast date: 1937-09-03)" +# For this script, you can assume to be provided the following information: +# +# * the value of $^T ($BASETIME) of the streamer script, +# * the value of time(), and +# * a CSV file containing the media to play consisting of the length in +# milliseconds and an identifier for the media (title, filename, or other). +# Write a program to output which file is currently playing.
