More software development

 I continue to develop the script that processes incoming movies. The script began as several separate scripts performing specific tasks. I combined them into a single bash script. Recently, I took up the task of local database development again. I have a lical version of the IMDB database in Sqlite format. A series of csv files comprise a local OMDB database. They can be imported into an Sqlite database as well. I downloaded what seems a reliable and accurate Kaggle version of the TMDB database to complete the set. I need to determine the metadata I will use and the source, then develop a script tobextract the data and import into movie files. This will rliminate the need for MetaX, though that app has many desirable features. One of the features fetches poster images for perusal and selection. That I can do but time and a list of sources will be needed. Until then I will continue to use MetaX. I do not intend to replace the program 'Rename My TV Series.'

February 2025 update - "moving the furniture"

 Rearranged the 'furniture.' Up to now, I've been using a lot of power strips to accommodate all the electrical plugins I have. Some at the rear wall for the power and Movie hdd bank. The HDDs were moved up to the TV. I removed the hdd shelf on the back wall and relocated the shelf just below the TV, accessible but not intrusive.I removed the two pieces of clapboard and replaced them with the plywood sheet that was holding the turntable over the AVR. The turntable has been removed to the top of the right Altec speaker cabinet. A center speaker module sits on top of the AVR. A blueray player sits on top of the left Altec cabinet. The three 3.5" sata drives and the 2.5" drives ,and their hub ,are now on the shelf.  I updated the Plex and Jellyfin software. The Senhneiser WiFi headphones are working but I removed the circuit board when the unit became intermittent and finally seemed to die. Removed from the plastic housing, the unit works acceptably, though the plugi...

Movie database

    I have, for some years now, been downloading and curating videos, mostly movies, covering the last 120 years.    There is a lot of work in acquiring and managing the collection. Methods of acquistion that were valid ten years ago, do not work today. Continual adaptation to the current technology is needed.    But I digress. During work with my system, I discovered the router was building a hidden database of  the contents of drives connected to the router. The file format is SQLite.    The online movie database IMDB, allows users to download the dataset. I did, and used a Python script, I discovered online, to create an IMDB database file in SQLite format.    For years, I've been cataloging all my disks using a small but fast cataloger named Cathy. All my movie drives are included. I hope to connect the databases together. Cathy can export a text file of a drive's contents.    There are two Movie database catalogers I ...
