It still amazes me, to this day, that people have jobs where they have the time to screw around on their computer all day. How do these jobs continue to exist?

I think people screw around for a fraction of the day, as a break from coding all day. It might make you more efficient overall. A bit like HIIT training for 10km vs. sprinting 10km. Also if the work is getting done its probably OK. When you buy that $10/month plan from Netflix, do you want to know that someone was working hard (not slacking) for 10 minutes at $60/hr ... or do you want to reliably watch movies?

Do modern notebooks still have vibration sensors? I think old ones had them in the hard drives, to protect them from damage. But SSDs wouldn't need that anymore. In any case, I wonder if detecting vibrations and recognizing the boss via machine learning wouldn't be more elegant.

Well, gait is usable as a biometric identifier. While most approaches use video analysis, I found this a paper [1] that is about identifying people through footstep induced structural vibration using a geophone[2]. It would be quite interesting if it is possible to measure the structural vibration using a laptops or smartphones built in accelerometers. But I think acoustic sensors would be a better way. Or a combination of both options.

I'm curious, what do you feel is the difference? Are you saying that you frequently lie to people you work with and that you feel that is acceptable? Or are you talking about having extra free time where you don't actually have any additional work?

I'm not lying to anyone about anything. The measure of what I accomplish is our ticketing / planning system and the pull requests I put up to complete the various work tickets.

I suppose you could try wiring the receiver up to a USB killer ( https://en.wikipedia.org/wiki/USB_Killer )... Though if you do that, you'll want to be extremely diligent about minding where you step :-D

You'd need to make sure it actually works, on Macbooks for example the USB ports are all fused so it only kills your USB ports but the rest of the computer is unaffected.

Not sure I believe that. I've watched Louis Rossmann talking about Apple's fuses.

But again, why lie about it?

To not embarrass everybody else who are also doing it, not least your boss.

Why would it be embarrassing to state "I currently have nothing to do right now, is there anything available I can help with." if you cannot figure out anything productive you could be doing on your own.

Are people's managers actually saying to them, "Yes, there is nothing you can do right now, just sit in your seat and do nothing until I come get you"? I've never had that experience, and is why I'm asking about it.

Why is there a receiver, instead of running an app on the receiving system to listen for bluetooth/http/etc messages?

Maybe because something needs to be at each end, to shine a laser at one end and to detect it at the other. Or you could use a reflector, but that's still two objects.

You don't need a reflector in the majority of cases, shining an IR laser onto a wall/door frame a couple of meters away is usually a big enough bright spot to drive a phototransistor pointing at (nearly) the same spot.

webcam vibration changing the field of view could be a decent proxy for laptops.

This reminds me of the old boss key: https://en.wikipedia.org/wiki/Boss_key

Exactly what I was thinking.

I remember being so confused by it as a kid when I saw it in games. Like, why do you need a key that displays a fake DOS prompt?

I could see real uses for these, but I'd want questions answered first such as whether they're specifically paired, where the programming is stored, what data passes wirelessly, whether there could be any way the receiver could act as an open HID receiver device, what the number of triggers is, etc.
