So many compiler errors after the most recent astrid IPC refactor, but they’re mostly sorted now this morning. Astrid is in a funny state now where it’ll likely blow up easily, but the edges around the new interfaces are mostly smooth.

The lifecycle is similar, but notably:

• aquire/release semantics only need a reference to the session, a handle to an empty resource struct, and a name
• for getting and setting the caller must know everything about the resource up front: in other words type & size with a void pointer to a valid memory space
• internally get/set just wraps aquire/release (except not fully yet, which is why things are still in a bit of a weird state!)
• all objects big and small are registered in LMDB as a resource header. the small ones also store their values directly in the header.
• that last bit allows get to be on a fast path: for small objects, reads can be completely non-blocking thanks to LMDB
• there are two types of locks: a session-wide lock used for LMDB writes (since the session is shared across all instruments) and each POSIX-backed object (large ones like buffers) has a lock

Christine Lemmer-Weber et al on Pet Names

This is a nice idea, I love how simply it shows relationships and provenance while at the same time making namespace-squatting (like high-priced coveted .coms) irrelevant.

I have had dreams about finding libraries of mini CDs with delicate sounds, intricate designs, and other stimmy things. There’s something wholesome about this that is hard to express within capitalism. Like dreaming about finding booklets or journals with lost communication. Delightfully secret documents, like the note you leave for your friend in the secret place you both know about.

Update: it is a beautiful day today in Winona.
