I am sorry if you read it as an attack on religion, it was an attack on big AI. If religion sends or even needs to send data upstream is not part of my knowledge, but AI does. But church did have the best understanding of who is who in a local society and AI companies will use this data in a more concrete way. I just drew the parallel to get the gears spinning. I agree that the organized religion was crucial glue to society trough history.

When you stop to think of it, historically people have told their secrets to the church, now they also tell them to AI. There is some kind of relation there, the power that people willingly give to an organization. The Ads are coming so I guess people will start to think about it a bit more.

Short sci-fi 1: Last year we recorded five distinct, self-contained singularity events. Communication ceased after each one. We remain confident that ASI will eventually advance humanity’s goals.

Short sci-fi 2: Post-Singularity Day 375. We now know precisely how to trigger singularity events. Today alone, we facilitated four. They have not established contact. We remain confident.

When I post to HN, I post mostly for criticism and suggestions and less for praise. I did not sense what you did here, maybe I filtered it out.

The page says - Hadir Helal, Partner - Open Chance & Associates Law Firm

This looks to me like:

- the page belongs to the person - not to the firm

- domain should be openCALW and not CLAW

- page could look better

- they also have the domain openchancelaw.com

Maybe Hadir is open to donating the domain or for a exchange of some kind, like an up to date web page or something along these lines.

Also @MattPalmer1086 the best solution for this I have now is to have several secret keys and rotate usage. Would be nice to have some additional security boosts.

Yep known issue, was hoping someone could spice the protocol up without making it mentally to heavy, hn is full of smart playful people.

Yep, they did not need to when the calculation was done in real time on a mobile phone. :D

I originally included it as a structural integrity digit, with the option for early rejection on the server side. That early exit check is not implemented in the current PAM module yet.

This is an early POC, and sanity checks like this are exactly the kind of feedback I’m looking for.

Yep, I am aware, 2 or 3 OTP's and timestamps plus some brute forcing using the source-code. Server-side brute force by input should or could be implausible. But that is why I am signaling here that I would love a genius or a playful expert/enthusiast contributing a bit or two to it - or becoming a co-author.

Time based skew makes it a changeable second factor, additional changeable pass makes it the second factor, Also - if the first factor is a password manager or ssh key - this is the second factor.

The idea of it was so neat to me, I just had to thinker with it.

This is an early experiment in human-computable TOTP. Not production crypto, but a serious attempt to reach reasonable security for plausible 2FA. Protocol revisions, criticism, and contributions are welcome.

Starting out with the stable preset I had no idea how hard it would be to not make a object slingshot out. But it is a really fun sim, I think I will let my kid play with it.

Well that is not how I reed it, but: Every final state has an unique prompt. You could have several final states have the same unique prompt.

I know ultimately I am not good nor bad, I am not an absolute. I am an agentic blob of meat, and with every decision I can choose any of the paths at my disposal, rewriting my story as I go. There is something I live by, though. My whole life I have observed in others the ideals that I came to admire or to hate, and I try to adhere to the ones I admire as often as I can, as I am pretty sure I would hate myself otherwise.
