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.

weechat has very nice remote frontend ability. i run mine headless with glowing bear there are also iOS and Android frontends

AMERICA F YEAH!

Agree. we should parse the form but not output to feeds.

@prologic@twtxt.net Oh.. reading comprehension is strong today.. you went to US and now back.

@prologic@twtxt.net Hol-Up. You are state side now? That’s a pretty big change!

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.

He loves freedom of speech so much he wants to buy a publicly traded company to stop a 14 yo from posting his private jet flight plans.

@novaburst@twt.nfld.uk Ah.. that is probably the XMPP verify code.. it doesnt really work that well. I aught to take it out.

@tkanos@twtxt.net Yep. https://twitter.com/jack/status/1510314535671922689

@mutefall@twtxt.net interesting.. were you working on one of the two universities that used it between 1989 and 1991?

@novaburst@twt.nfld.uk what is it?

Connection Established!

@prologic@twtxt.net yeah. For commercial use even. Just need to put an attribution note in the project README

@prologic@twtxt.net +1

I set mine to 4096

@prologic@twtxt.net if we do adopt this one it is CC-BY from twitter. https://twemoji.twitter.com

@lyse@lyse.isobeef.org Excellent use of old denim, and also excellent use of long-form twt!

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.

@novaburst@twt.nfld.uk I doubt there will ever be a 2.0 … It may end up like java and they strip off the 1.

@ullarah@txt.quisquiliae.com works for me! A tricky bitmight be if it splits within a codeblock so markdown can’t parse

@prologic@twtxt.net I have seen single use keys that are signed by a central PKI .. Keybase has one that uses a chatbot to generate the keys on the fly.

It just comes down to your threat model :)

https://book.keybase.io/docs/chat/crypto

@prologic@twtxt.net for shame! lol me too.

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/

@prologic@twtxt.net yarn builds in 1.18!

@prologic@twtxt.net hmm so each individual feed on your pod sub’s my feed? Wouldn’t that flood your server for each post?

Okk

@prologic@twtxt.net wat

One down! More to go.

@screem@yarn.yarnpods.com we have had to really shorten our process. I think long interviews were scaring off talent.

@screem@yarn.yarnpods.com yah I finally saw all of Dave’s twts and figured he had explained Gog’s/gitea better.
