That smells a bit like a transaction to me.

Wouldn’t the biggest problem will be loading sleds into a hot rack, with all of the sleds powered down? Which probably you shouldn’t do. The parallel loads on a rack that’s half on should sink a lot of the potential.

Only afterward did I realized I almost destroyed my livelihood.

My partner Google stalked the owner and discovered that he’d been force to surrender another pit bull two years earlier.

With that sort of voltage you should be able to use a capacitive or inductive sensor to activate a relay.

One of my kids has taken this advice, does art (really good art) for themselves and is pursuing a STEM career instead. The other is pursuing a game dev career, despite every current and former dev in his life warning him off for the last fifteen years. To quote Kissing Jessica Stein, “OY! This child will suffer.”

The old fastCGI trick is to buffer the forking by idling a half a dozen or ten copies of the process and initialize new instances in the background while the existing pool is servicing new requests. By my count we are reinventing fastCGI for at least the fourth time.

Long running tasks are less sensitive to the startup delays because we care a lot about a 4 second task taking an extra five seconds and we care much less about a 1 minute task taking 1:05. It amortizes out even in Little’s Law.

Eight months ago he built a quadrupedal robot that could step sideways using three of them per leg. I’m not going to link that, you’ll have to find it from his YouTube page because you should look around.

Apple did patent a design for a dock in a monitor for a portable device to slot into. It’s gotta be getting close to expiration now. I think the trick is heat dissipation.

My friend who is a macOS programmer years ago had an idea for a startup mode for iMacs where instead of just being a screen, the storage and video card would also be accessible over the thunderbolt bus, so you could plug a laptop in and have multiple video cards at your disposal.
