I have, and use Calibre with LL instead and it still requires a lot of hand holding and manual grooming to get a clean library.
My big issue with Readarr is that it had a hard time fetching data for various popular and/or prolific authors. So if I wanted to fetch all the books for a particular author, there was a high likelihood it wouldn’t actually fetch the necessary book data to do so.
I prefer LazyLibrarian over Readarr but it still leaves a lot to be desired for end-user usability. One of the big issues with ebooks is that data is a mess, with each book having a billion different editions with spotty metadata support that makes it hard to tell what is what.
Goodreads seems like it was a decent source of data for these types of projects but they shut off new API access a couple years ago and legacy access can go away at any moment. Hardcover seems like a promising API alternative but not sure if anyone has started integrating with them yet. Manga and comics seem to be in a better state, with a more rabid fanbase maintaining data but still nowhere near what’s available for movies and tv.
There was most likely a closet or other crawl space storage area there. My house has closets like that but luckily full height entries to them so we can actually step in. I’ve seen other houses with 1/2 or 1/3 height doors leading to under-roof crawl spaces for storage.
It’s cheaper if you don’t have constant load as you are only paying for resources you are actively using. Once you have constant load, you are paying a premium for flexibility you don’t need.
For example, I did a cost estimate of porting one of our high volume, high compute services to an event-driven, serverless architecture and it would be literally millions of dollars a month vs $10,000s a month rolling our own solution with EC2 or ECS instances.
Of course, self hosting in our own data center is even cheaper, where we can buy and run new hardware that we can run for years for a fraction of the cost of even the most cost-effective cloud solutions, as long as you have the people to maintain it.
