In short, a modern chronograph tells the time traditionally and, using a distinct mechanical complication, also can record seconds, minutes, and hours (usually) in a stopwatch-style function. The mechanism was soon miniaturized and added to pocket watches.

These recorded on two rotating discs of paper the difference in time between two horses on a race track. Its name is derived from one of the earliest versions of the mechanism, which was essentially a box filled with clockwork attached to two inky styluses. Is there a way to tell Syncthing to automatically check whether Calibre is open, and if so, not to do any syncing? This could also be some kind of external shell script.Chronograph means “time writer,” but you can think of it as a stopwatch, activated and stopped at the whim of its user. While this works, it’s pretty cumbersome, and not practical because sooner or later I’m going to forget and end up with Calibre and Syncthing running at the same time, and potentially corrupt the Calibre database. run Syncthing on desktop and allow the changes to propagate to laptop.use Calibre on desktop, make changes (add PDFs, edit metadata, etc).make sure desktop does not have Syncthing running.

In other words, do not run the file syncing tool and calibre at the same time. If you are using a file-syncing tool it is essential that you make sure that both calibre and the file syncing tool do not try to access the calibre library at the same time. If you must share the actual library, use a file syncing tool like DropBox or rsync instead of a networked drive. However, I’m a bit spooked by the warnings made in the Calibre documentation: I pointed Syncthing at my Calibre directories and so far it seems to work: changes made to the database on one device get propagated to the other. I want to use Syncthing to synchronise my Calibre library across two devices (desktop and laptop, both running Linux).
