> opportunity to take the bulk components off boards, test and sort them, and sell them in bulk.

I think this is already happening in China for certain components.

I think it's the PDF files that were attached to the emails, since they're base64 encoded.

10+ years experience building web apps and services, computer is my hobby. Currently an engineering manager that still codes and work with PMs. My current job consists of talking with PMs, sorting out initial requirements and leading the team through thorough feature refinement process, also discussing with operations team to lay out plans for new features.

Looking for a change since my current company got acquired, and I've been in this role for quite a while now. Hoping to work on something meaningful, to myself or the community.

I interpreted "inactive" as the link that the shortener is linking to is not responding.

Made it sound like it's a computer, is it Turing complete?

This exactly scenario is why our company is so afraid to put AI into production without the results being completely clear that it could be wrong. But if there’s even a chance that it could be wrong, why are we offering it to the user? How much due diligence does the user need to do? Does the benefits outweigh the cons?

That sounds more like Alibaba, where it operates like a B2B type transaction. In my experience, just talk to them, sure it might take more time but you can usually get a good price if you’re buying higher quantities.

Probably need to store the bucket on some kind of persistent storage like ElastiCache?

USB! I’ve tried and failed couple times in understanding how USB works under the hood, from electrical, to protocol, then classes, and also Power Delivery. This time around things seem to make more sense now. It started out as an ambitious goal to emulate an FTDI USB DMX converter with the ESP32-S2/S3, but realizing that might be too big a goal, so I’m starting small. I want to be able to make a custom device class on the ESP32, and write a driver with libusb.

Basically embed a layer of transparent text to the PDF that's invisible to humans but visible to whatever PDF parsing software which will only get processed by LLMs

> Ai is not able to create original knowledge

The current state of LLMs do hallucinate though. It's just not a very trustworthy source of facts.

Isn’t that like almost all of medical devices though? Including ones that have critical life sustaining functions.
