So what happened was, I fed up manually uploading pictures I export from Darktable to my Flickr photo stream using the browser's file picker. So I decided to do something about it. The initial idea was to craft a FUSE file system which would automatically upload new files, but this turned out to be hard, so I switched to a much simpler solution: a little inotify watcher handing over new files to an upload script. I managed to code up a working solution over a weekend!
More interestingly, I made the watcher part — "nfp", for "New File Processor" — as a generic configurable tool which I published. It was only when I started writing this very blog post that I stumbled upon a standard Linux tool that does it, inotifywait :-)
Still, I hope there's something to be salvaged from this project. Read on!
