Wow, this is really cool. I really needed something for my neo retro build, this might just fit the bill.

Created a react-doctor style cli to deterministically scan for misconfigurations, missing observability, and security posture. Now working on extending it so vibe-coders can secure their apps too!

This is so cool! Loved your agent instruction snippet too.

Working on pg-fs, a postgres backed file system abstraction for ai agents. So I agents can be given their familiar file primitives, without

A version of it powers my local rubber duck thoughts and voice note store. Like an explicit chatgpt memory store, helps with information fomo cause I know finding the needle in haystack would be easy.

It would, probably, be cost prohibitive to use 10M context to it's fullest each time.

I instead hope for to have an api to access to the context as a datastore, so like RAG we can control what to store but unlike rag all data stays within context.

Its still a work in progress. https://github.com/DumbMachine/pbs/ to use a keyboard to interact with web. It's like vimium but tailored to my liking:

- hints are acronym of textContent ( or metadata ) of html elements.

- A command bar with fuzzy search for browserhistory.

Helped reduce mouse usage, which I think was causing strain on my wrist.

Considering they are in the same segment, Adyen seems to be doing fine. EPS of 17.64 https://finance.yahoo.com/quote/ADYEN.AS/

Could be a result of smaller product suite and headcount of Adyen.

I don't follow enough users to have a flourishing newsfeed, so facebook gives me suggestions to follow pages and shows posts from those pages. These suggestions are purely based on what facebook thinks I may like.

With people having enough sources to feed their newsfeed, facebook decides the order and cherry picks what posts are shown.

> Is facebook wrong for showing you the things you said you want it to show you?

I do agree with this. Coming to a solution to this would be hard problem. Users will have to give finer information about types of posts people like from a creator. I doubt there are any real work incentives for a big company to build a system like this.

By adding content to user's newsfeed, they ( facebook's algorithm ) have made a explicit decision to share the piece of content and implicit decision that they deem the post safe for sharing. In that case shouldn't a speaker operator be responsible for the voices they amplify?
