Probably the scale and usability of things. It's different if you're controlling 100 LEDs vs 5,000.

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.

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.

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.

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

They only need the server's public key to encrypt it client side. But if all you want is to see if they're spying on you, you could go one step above and see if they're calling system APIs to your mic/camera/keyboard, instead of observing the network activities.

I never find the speed and acceleration of the Apple Trackpads slow. Out of curiosity, how are you moving your fingers when you want the mouse to travel long distances? What I do is repetitions of the movement on same area of the trackpad , e.g. my finger never drags more than two inches of the surface. I also have tap to click disabled, and use my middle finger to move, thumb to do left click, and middle + ring finger for right click.

This would only work assuming the IRS knows who Satoshi is, if they live in the States at all. One would also have to proof to the IRS that you own the addresses, do they understand public key cryptography?
