That is not how it works.
When you short something to ground, it’s everything in between that needs to dissipate the heat. Think about what “sending it to ground” means—it means you connect the hot to the ground. But with what do you connect the two? A wire? Sure, but you better hope that wire can dissipate all that power, because that’s what it’ll try to do.
You can’t just “dump power on the ground.” That’s not how it works.
This gets posted regularly on Lemmy, and while the economic take is tone-deaf at best, there’s a real issue with generating more power than you can use. You can’t just dump grid power — it needs to go somewhere. The grid needs to consume as much as it generates at all times or else bad things happen.
There are of course solutions, but that doesn’t mean it’s not an engineering challenge to implement.
Figuring out what to do with kilowatts is easy, but figuring out what to do with megawatts, at the drop of a hat, is substantially harder.
The all-wheel-drive ES 500e returns up to 276 miles of range.
For those who want AWD, range will be somewhat reduced.
You want an instance? I can get you an instance, believe me. There are ways, Dude. You don’t wanna know about it, believe me. Hell, I can get you an instance by 3 o’clock this afternoon… with Achievers. These fucking amateurs…
You can/could also find Coffee HOWTO in your distro’s HOWTO package. (I found a reference back to v0.5 of the document in 1998.)
Has simple schematics to get you started for the hardware, using the parallel port to toggle relays.
It’s a very neat little document, and inspired me to write a simple kernel module so I could echo 1 | sudo tee /sys/whatever/coffee0 to turn pin 0 high on the parallel port. (This is silly, and it’s much easier to just do things in user space!)
This is the element Ru (not some whacky AI backed cryptocurrency).
March in San Francisco is feeling like August in LA.
But what if the foe is really the Epstein files?
"While I’m up here I want to shout out all of our friends and neighbors who couldn’t be here tonight. Our international friends and neighbors who cannot safely travel to this country. Our immigrant friends and neighbors who cannot safely travel inside this country. Our trans friends and neighbors who cannot safely travel after having their driver’s licenses revoked overnight without warning by a cruel and unnecessary legislative act.
“Our friends and neighbors in places like Iran, Venezuela, or Gaza who fear for their lives on a daily basis because of cruel and unnecessary violence. I don’t have any plans to stand on this stage again anytime soon, but if I ever were to do so again I would want it to be amongst all of my friends and neighbors, safe and thriving.”
Never done meshtastic, but I do a little amateur radio. For a high gain antenna, do you just experiment with where it’s pointing, or do you point towards something in particular?
I brought this up to my ex over the course of our usual conversations

I’m really really glad that I get root on my work computer.
I have heard, but have trouble finding references to it, that you can build a simple arbitrary waveform generator circuit by using an analog scope, a photodiode, and a cardboard cutout.
You make a photodiode circuit that rails high with no light, but light on the photodiode pushes the signal low. Then you aim this at the phosphor screen with a cardboard cutout of the desired waveform: signal goes up until the phosphor trace is above the screen, and then it gets pushed low (i.e., feedback keeps the trace right on the edge of the cardboard).
Never seen it in action, but I choose to believe it works beautifully :)
I think glass is technically an amorphous solid .
Not sure “asshole” is right for Torvalds…maybe there’s another word to describe him…
(See the last bit in Notable Usage.)
“…I really don’t want to have to wipe the thing because it’s running a headless OS”
I feel like logging in as root on a headless system and hoping you type the command(s) to restore functionality is a rite of passage.
AWS was recently “having issues” due to the Iran situation — same thing I wonder?
After reading a few of these I feel like I was either a very boring grad student, or my professors were all very chill. (Or maybe just subject to male privilege.)
A few run-ins with IT, but I don’t think I ever got nasty letters from professors…
If it’s a low resistance path to ground, it’ll get very very toasty! If it’s a lousy ground though, then it won’t…but it also won’t consume any power, so it’s not an effective way of scrubbing off electricity.
A good ground (low resistance) is found in your household wiring (the ground and/or the neutral). Of you short to that…well…you can guess what will happen! (Let’s hope you have proper circuit breakers.)
