FYI, banks do run exactly this type of analysis inside their own system to get around not being able to share your account activity.

Yes, the center (neutral) is connected to ground somewhere, but is not a suitable ground reference - because current on the neutral creates a voltage drop along the neutral conductor. A North American outlet box has Hot (L1), maybe another Hot (L2), Neutral, and also an earth/ground conductor.

Neutral is not ever treated as ground; it’s impermissible to connect it to any bare metallic surface. Other than not being switched, and being the side that ends up on the threads of a light socket, it’s handled the same way as a hot/line conductor. Just like a 240V system.

It would dissipate static fine, if you were allowed to touch it.

I think that’s incorrect. The ground pin is a dedicated equipotential reference bonded to the earth via an acyclic wiring path which carries no current. It does go pretty directly to the ground rod via the breaker panel ground bus. Neutral happens to be connected to it at the entrance panel for fault clearing, but not really for any other reason.

Since all metallic chassis, pipes, ducts, etc are connected to it and it is available pretty much throughout a building, it is a logical place to connect ESD-prevention gear, even if the earth has little to do with that. (But, a grounding electrode system installed to code should have less than 25 ohm impedance to ideal earth - not exactly a “poor” conductor)

The thing is, it may not “break” them but may introduce difficult to localize unreliable operation - which you may even explain away as buggy software.

IC’s, especially small feature size CMOS, absolutely are subject to ESD damage.

honestly, I don’t want established Reddit supermods land grabbing topics in the Fediverse. The right people will find it organically based on their own motivation (as simple as searching for “reddit alternatives”).

Especially don’t want the shallow, low-quality content from default/“top” subreddits.

By definition, the 1% are the top 1% of earners in the population, so there are 8,100,000,000 * 0.01 = 81,000,000 of them, not 400.

The richest 400 are the 0.000005%.

The 1% line in the US is at $819k a year, and $60k worldwide.

One thing that I learned recently from the Modern MBA YouTube channel, is that these fast food brands don’t run stores – they primarily charge franchise/royalty fees, and the store operators/franchisees see a significantly different and lower-profit-margin situation.

“McDonalds Corporation” is not where these expenses accrue.

“prove it wrong”? “as we’re told”? Do you start conversations this way?

Bro, if you don’t like it you don’t have to use it.

Betavoltaics have been around for 40+ years. https://en.m.wikipedia.org/wiki/Betavoltaic_device

This device generates microwatts. You’d need thousands of them in parallel to power a typical mobile phone.

All of their tech job openings are in India or Vietnam. I’d have assumed a major US health data handler would be developing onshore!

Schizoidman, do you work for BYD?

For most organizations, the cost of paying programmers far exceeds the cost of CPU time; benchmarks really should include how long the solution took to envision/implement and how many follow up commits were required to tune it.
