The only problem is that most people don't have a reason to go there. The streets are usually empty aside from the homeless encampments.
The only reasons I've ever had to go to DTLA was to attend a conference and some games at the Staples Center. It's a cultural and recreational wasteland compared to the rest of the city.
The real area of focus for reducing traffic and vehicle usage should be the San Fernando Valley corridors (Sepulveda/405, the 5, and the 101 to San Gabriel Valley). Iirc from a recent report on KPCC there's like 600k daily commuters between the valley and the southland, and another 700k between the valley and San Gabriel Valley.
We have one metro stop in the SFV, which serves the 3 million residents. It's no wonder it's surrounded by a massive parking lot, and most commuters don't use it anyway.

In the context of 8chan, I think there's a difference between allowing people to say whatever they want online and punishing the people that use that freedom to incite violence.
The part where it gets blurry to me is the hateful rhetoric that doesn't directly call for violence, but the only logical conclusion of the position is genocidal or otherwise racial violence. Talking about "invaders" or "American cities under foreign occupation" for example.
What's the advantage of hand rolled CPU dispatching over compiler intrinsincs like function multiversioning in GCC/Clang?
Same thing happens when you play an instrument.
What a voltage does is pull or push the charge carriers. When lots of them flow, you have a current. Conductors, like a wire or ground rod, are full of free electrons to act like charge carriers (kind of like a pipe filled with water, the voltage is a pump that moves it).
The duality of pulling/pushing charge carriers is why we need a circuit. In order to push charge carriers, we need something to pull them from (a source) and somewhere to dump them (a sink). When we have no source and no sink, charge carriers have nowhere to come from and nowhere to go.
Ground is a convenient source/sink for charge carriers because it's roughly uniform in charge and huge, so pulling tons of charge carriers from it doesn't impact it greatly.
And it's not that charge carriers are always flowing back to earth, but back to their source. That's why ground is sometimes called a "return path." To move a charge carrier, you need to give it potential. It will lose that potential and return to the point of lowest potential difference from its origin - which is its origin.
But that said, for things like AC power, the charge carriers aren't actually moving very far at all and have a net displacement of 0. They vibrate adjacent charge carriers, and we convert that vibration into unidirectional (DC) voltages that can push/pull from local sources/sinks, be it the literal earth (mostly for safety ground) or a small plane of copper on a PCB.
It provides a nice visual for why current always makes it back to ground, just like water always flow downhill. It also removes the tendency to anthropomorphize electrical current and say things like it "seeks out" ground. When something falls from the sky we don't say it's trying to find the ground!

> Cutting or girdling trees with power or manual saws are effective at preventing seed production, but an herbicide treatment is necessary following cutting since Paulownia readily re-sprouts. Hand pulling may be effective for young seedlings. Plants should be pulled as soon as they are large enough to grasp. Seedlings are best pulled after a rain when the soil is loose. The entire root must be removed since broken fragments may re-sprout. Cutting or pulling is the preferred mechanical treatments of the Paulownia tormentosa; do not use fire because this species is able to survive fire and then quickly proliferates and out-competes native tree species post-fire.
If you use it to track subsonic audio watermarks to detect what advertisements I see on my TV or find out what products and services I'm interested in, screw off.
Every engineer who pushes code to synergize advertisement business with their consumer audio product business should be ashamed of themselves. It's unethical and should be illegal.
I want the products I buy to do what I think they do. Not hide tracking used to improve other products from the business that I don't pay for.
I don't think there's one pretty solution here. You'd have to break it down a bit.
- Do the patients go to the machine, or machine to the patient? Wireless makes sense for the latter, not the former.
- What's the failure mode? An alarm/alert to the nurse station, or death? Wireless makes sense for the former, I think.
- Are there any machines at every bedside? Do all of them need to be used at once? Detachable/modular cabling might make sense here.
- Are the cables different? Or can you come up with a "standard" cable/connector for most of the gear?
The audio world solved the "cables being knocked out" problem a long time ago with locking connectors (not screw-ins, so they're still quick connect) like Speak-On and XLR. The former is much more formidable.
But I get what you mean. Even without getting into my inherent distrust of facial recognition systems and the security/privacy implications of creating the infrastructure for it to work reliably, biometrics are usernames. They shouldn't be used as passwords.
