My university recently discovered a covid outbreak at my freshman dorm by testing the wastewater; that was the first I heard about the technique. It's especially effective for this use case: "Traces of SARS-CoV-2 can show up in an infected person’s feces days before any symptoms are detected, and even when a person ultimately shows no symptoms at all."

I'm working on a private social media app for (me and my) friends who workout together. Making a beta version of the app with flutterflow (low-code, bit buggy) to see if it is what I think it is.

I wish all explanations made complicated concepts this manageable!

> the simplest way to differentiate most discrete objects (like database insertions) is to insert them probabilistically and apply your derivatives/slopes to the likelihood of the insertion succeeding.

I hope it wouldn't trouble you to go a bit further with this idea? Namely, the idea of differentiating an object or database insertion sounds like it shouldn't be structurally possible.

And why would there be a probability function for a db insertion succeeding? How could it fail - if the db was full or if there are too many requests?

I'm astonished that it works! To my understanding, the 128GB has specifications for how to "talk" to it on its datasheet and same with the 1TB. Do they have the same manufacturer for them to have the same pinout?

And, how come they're the same size lol. Intuitively, I'd expect the 1TB to be way bigger.

This is so damn interesting. I've downloaded the github files, but it's all going way over my head. I would greatly appreciate anyone with domain expertise giving me the one-two on getting my own model up and running.

Me too, 3 months ago in California.

> part of the progress is due to serendipidy.

Serendipidy means something like unexpected good fortune, but the folktale it comes from (The Three Princes of Serendip - weirdly nostalgic, link below) implies a different meaning.

The princes don't roam around with unbelievable luck; rather, they are aware of the world around them and consider what it implies.

Probably its meaning now has somehow evolved, which is cool. I pay a lot of attention to the (current states of) evolutions of things. I see it as a kind of refinement process, where valuable things persist. So the valuable thing in question is the idea of unbelievable luck and the raw material was a broad awareness of your surroundings and its implications. Maybe, through generations, people came to understand that the latter manifests the former and this realization became reflected in the usage of the word, resulting in its evolved (current) state.

Consider the sum total of all human reason required to evolve this word as the intellect of one person. This superintelligence has then made explicit the idea that awareness manifests luck, which also makes intuitive sense.
