musings

this is something like a public diary.

in the past i’ve attempted to do a wiki sort of home page, but inevitably there are more dead links than time to fill them in, and some of the content gets rapidly out of sync with my current thoughts on things.

this section is explicitly light on organization, minimal on proof-reading, no effort-posts, just an append-only repository of thought.

i most likely didn’t fully endorse any of them at the time they were written, much less as time passes.

EA discourse crossed my path again, so I ended up reading a bit more what Émile Torres has to say. I hadn’t quite realized how much they blame AI doomers for the current AI race/bubble/mania.

maine, where i live, passed a ranked choice voting referendum six years ago. when the folks pushing it called me, i remember saying that, while it’s better than plurality, i preferred approval voting.

that’s still true.

i’ve been prototyping versioned nodes implementations. one thing that is proving difficult is managing the sheer number of types of capabilities.

so i’m playing with a virtual machine idea based on closures. basic idea is that each procedure takes a fixed number of inputs, and a call either adds insufficient inputs and so returns a new closure or adds enough inputs and so invokes the procedure (which returns whatever it returns).

every so often i need to render some data in human-typeable form. sometimes that leads me to my one-word-per-byte encoding. other times it leads me to the various n characters per m bytes encodings.

one very popular fully encrypted transport protocol over udp would make traffic analysis of fully encrypted protocols much harder.

got some thinking to do on luggage sizes

had a strange idea for a magic system…

there’s apparently technical guidelines¹ that talk about turning random bits into random numbers between 0 and something other than powers of two. unfortunately it’s lacking a bit of nuance.

i’ve been using a pair of (relatively) cheap ar glasses as my primary display for a few weeks. overall i like it a lot, still need to get lens inserts to correct my elliptical (and a little interpupiary distance difference). but it’s only 1080p per eye, so of course i’m looking at how to build something better. which end me up looking at datasheets for ti’s mems display chips…

i’ve been wanting a good way to migrate signature keys in converge. ideally a migrating key pair that:

signatures can be verified correct with merely the signing public key
the migrating secret cannot be derived from the signing secret key
even if the migrating public key is known

in cryptography, we often require domain separation for different uses of the same primitives. roughly, this means ensuring that the inputs to a primitive for different purposes cannot overlap. so there are no instances where you can lift a value from one part of the protocol and use it in another.

i’ve been thinking about data confusion - interpreting the same pile of bytes as different types.
