+Date Created: 2021-01-25T00:36Z
+
+Create or adjust executables so they write latest sensor values to
+~/dev/shm~ so other scripts can read values from them for other
+purposes (i.e. periodically reading and piping into ~bklog~).
+
+Ideally, the scripts should output sensor data in ~jsonline~ formatted
+to use an appropriate ontology (i.e. [[https://www.w3.org/TR/vocab-ssn/#iphone_barometer-sosa][SOSA]]).

+** TODO Prevent ~systemd~ from removing ~/dev/shm~ user files
+*** 2021-10-31T21:53Z
+~systemd~ may be automatically removing ~/dev/shm/ninfacyzga~ and
+other files used to store photograph script state. [[https://superuser.com/a/1179962][This]] SuperUser post
+explains how this default ~systemd~ behavior can be disabled.
+
+Disabling the behavior requires modifying
+~/etc/systemd/logind.conf~. This would add another step of complexity
+with possible sideeffects if other unknown programs are writing to
+~/dev/shm~ and system stability requires these be regularly deleted.
+
+[[https://github.com/systemd/systemd/issues/4532][This]] post indicates that the RemoveIPC behavior only occurs for
+non-system users. Another possible solution would be to run the
+photograph timelapse script as root; however, this would require
+making sure to write the output files as the ~pi~ user to prevent file
+permission issues. For now, the ~systemd~ defaults will persist.

 with ~gpsd~ seems simpler as well. The fact that it displays time
