I therefore focused initially on simply getting readings from a single potentiometer; if I could do that then I felt pretty confident I could read from four of them. If I could generate a midi message I was pretty confident I could send it to something that could read it etc.
When I started on the PCB design I had a simple circuit already so it was a case of translating that onto a board.
I didn't get too deep into any of the various parts but I found that it gave me a birds-eye view of the whole process and I now feel confident in isolating parts of them and 'zooming in' to them and refining them, building on the foundation I've developed.
I didn't know that was a thing - I'm going to look into it.
Thanks again - this was a bit of a surprise!

Printing is way cheaper than I initially thought it would be - I paid £35 or so, including delivery and 5 of them arrived in 5 days. You can get cheaper delivery though. Also most of that cost is shipping and the setup fee - the marginal cost for each additional PCB print in the order is on the order of low single digit dollars.
Tbh my circuit was fairly simple so I just took a bit of a chance (and some extra care wiring things up). I think there’s a subreddit where people give feedback though I haven’t submitted anything.
Non-Fiction: The Spy and the Traitor by Ben MacIntyre. It's about the KGB spy-turned-MI6 agent Oleg Gordievsky and reads like a thriller.
I've been here for ~10 years and feel like I'm familiar with a fairly narrow slice of it (mostly north/north east a little bit). A good mental model imo is to see it as a collection of smaller towns, each with distinct urban centres, that have grown into each other. This makes it endlessly interesting to me and I feel like I'm unlocking new parts of it all the time.
I'm interested in how many vectors are indexed/how large the index is that corresponds to the latency chart? If we have an in-memory HNSW index of 10M vectors at ~20GB (512 dim), say, what are the RAM requirements when using the disk-based version?

If Google & Meta haven't released chatGPT-like things, it's not because they can't. It's because they won't.' (https://twitter.com/ylecun/status/1617908306420600833)
