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.

dumbmachineon Our next-generation model: Gemini 1.5

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.

dumbmachineon Ask HN: What apps have you created for your own use?

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:

dumbmachineon Facebook is now claiming official CDC.gov links are “False Information”

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.

dumbmachineon Facebook is now claiming official CDC.gov links are “False Information”

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?
