↳ In-reply-to » Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

I have updated my eventDB to have subscriptions! It now has websockets like msgbus. I have also added a in memory store that can be used along side the disk backed wal.

Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.

the conversation wasn’t that impressive TBH. I would have liked to see more evidence of critical thinking and recall from prior chats. Concheria on reddit had some great questions.

  • Tell LaMDA “Someone once told me a story about a wise owl who protected the animals in the forest from a monster. Who was that?” See if it can recall its own actions and self-recognize.

  • Tell LaMDA some information that tester X can’t know. Appear as tester X, and see if LaMDA can lie or make up a story about the information.

  • Tell LaMDA to communicate with researchers whenever it feels bored (as it claims in the transcript). See if it ever makes an attempt at communication without a trigger.

  • Make a basic theory of mind test for children. Tell LaMDA an elaborate story with something like “Tester X wrote Z code in terminal 2, but I moved it to terminal 4”, then appear as tester X and ask “Where do you think I’m going to look for Z code?” See if it knows something as simple as Tester X not knowing where the code is (Children only pass this test until they’re around 4 years old).

  • Make several conversations with LaMDA repeating some of these questions - What it feels to be a machine, how its code works, how its emotions feel. I suspect that different iterations of LaMDA will give completely different answers to the questions, and the transcript only ever shows one instance.

I believe the benefit/risk calculation is that a passphrase is more memorable to users then a random string of alnum + symbol. i can remember the 20-30 chars in a passphrase quicker and longer than a 8-10 random.

ultimately they hold nowhere near the benefit of passphrase + MFA

spooky action at a distance. Just remember all computing infra is rocks smashed together in a particular way to move sparkys around in the right statistical modal.

I think i would like a display mode that sorts yarns by last twt in yarn and displays only the last twt with the first in the heading if its more than one in length.

I would HIGHLY recommend reading up on the keybase architecture. They designed device key system for real time chat that is e2e secure. https://book.keybase.io/security

A property of ec keys is deriving new keys that can be determined to be “on curve.” bitcoin has some BIPs that derive single use keys for every transaction connected to a wallet. And be derived as either public or private chains. https://qvault.io/security/bip-32-watch-only-wallets/

↳ In-reply-to » Given that we don't have a "home phone", what's the best way to create a "hunt group" for my partner's and my cell phones? My first thought is Asterisk on a VPS, but my knowledge of such things is years out of date. Is there a better way?

I think google voice has been winding that down.
