Go ahead and try scraping an arbitrary list of sites without an API and let me know how that goes. It would be a constant maintenance headache, especially if you’re talking about anything other than the larger chains that have fairly standardized sites

Because grocery stores don’t make that data accessible to third party developers, otherwise someone would do what you’re suggesting and they’d risk you shopping elsewhere.

Give NixOS a shot. It’s got a learning curve that may be difficult if you’ve never read code, but it’s my preferred immutable setup.

It even has more packages than Arch.

Here’s the video that got me onto it:

The code is available here:

Yes I do! It’s a pretty great overview that isn’t extremely math heavy

The book is “Deep Learning for Coders with Fastai and PyTorch: AI Applications Without a PhD”

I have a book on learning Pytorch, this XKCD is in the first chapter and implementing this is the first code practice. It’s amazing how things progress.
