At the back end of the 90s I did some work with self-organizing maps - collapsing multi dimensional space into a 2D map. I think it's interesting as a data visualisation approach. This looks similar but I'm totally out of date with where SOM went.

When you say 128d space, what are the data that are represented, exactly?

Hello! I find these fascinating too. The 128 dimensions I mentioned are learned by the NN, they are latent space and their actual meaning is ultimately unknown. The number itself is somewhat arbitrary as it was selected optimizing memory usage vs data coverage so that the track embeddings could sit on an A100.

I first met Rob in 2012 (https://wiki.musicbrainz.org/MusicBrainz_Summit/2012_Mini-Su...). His enthusiasm, intelligence and drive were, and remained, evident; a truly impressive person to work with.

Truly, one of the Internet's good guys, and the type of positive force we can all take inspiration from.

Not only do A&A offer good speeds, their customer service is exceptional. There are chat rooms on which engineers and enthusiasts reside and if you phone them you get an engineer.

Is there a way of testing two points to see if they can communicate with each other before I go to the trouble of wiring to a rj45 endpoint?

I'm not convinced socket A can talk to socket B when, for example, socket B is in an extension, or... or...

Short two wires on one end, go to the other end with a multimeter and test for continuity between those two wires on your lowest resistance range. If it is infinity then no connection. If it is some low number then there is a connection

Fantastic - thanks!

As a complete hardware newbie, how would I go about starting creating the PCB? You have something codified for the case, but not the circuitry.

Are you referring to this project specifically, or in general, how to create a PCB? If you want to create this project, you would need to download my exports in GitHub releases and send them off to a fab house, like JLCPCB. If in want to create a PCB in general, it's more similar to a connect the dots game, I used KiCad for this project

OP could use something like mp3fs to make the transition from MP3 to FLAC less painful where MP3s are still required - it's a lazy mirror of a FLAC collection to MP3.

(Disclaimer: this relates to the commercial project I run, but it is directly answering the parent)

It's not self hosted, more a middle-ground between rented Spotify and self hosted data sovereignty, but this is what we do at https://asti.ga . You store your music in some Internet-accessible storage, such as any S3 compatible endpoint, and Astiga connects and streams your library (and provides offline etc etc). AMA.

Very relevant to my interest, thank you for posting, I wouldn't have found you otherwise.

You could get images from multiple perspectives from the Cover Art Archive (via MusicBrainz). E.g. https://musicbrainz.org/release/a4f190d5-c752-4ebd-8d2f-925a... . It would be very cool if the spine could be rendered, although it's not always split from the back image (I guess because of the post processing after scanning).

Yes - and/or data sovereignty.

The tragedy of of this is that these are improvements that would actually improve life in these houses - making them healthier, more comfortable. Trouble is, retrofit is expensive.
