Comment Re: Decision making that has little to do with log (Score 2) 233

Liquidity risk is absolutely a form of financial risk that any competent bank will track and manage, as is the market risk associated with any investment. SVB failed to manage the market risk associated with the rising interest rates and their effect on the market for bonds and mortgage-backed securities; that created the liquidity risk that they wouldn't be able to survive a run on the bank. A competent CRO would have noticed these risks and raised the red flag before the Fed got there; instead, SVB also created unnecessary regulatory risk by ignoring the Fed's warnings. By taking that regulatory risk, they wound up having sanctions against them that further limited their options.

Banking is risk management. Banks make money by betting on investments and betting that they can make loans that will be paid back. These risks are manageable, if one doesn't get greedy. SVB's management walked into the casino, went to the roulette table, and put it all on zero.

The problem is that they installed motion detectors in a place where they needed occupancy detectors. Yes, they both exist, and there is a difference: occupancy detectors don't require motion, just a human-scale heat source. Or, possibly, a vacancy detector—a type of switch that requires you to turn the lights on manually, but will turn them off when the room has been vacant for a period of time.

When I worked for a major photocopier manufacturer, the field techs had a standing order to copy any signs or instructions pertaining to the copier's operation found on or near a copier being serviced. They were to be sent to the engineers, as they represented a design failure. It was felt the copier was a simple device to operate and shouldn't require written instructions at the point of use. They were quite good with UX at the time. For instance, all parts the user could manipulate were color coded at the point of touch: blue for things related to putting blank paper or toner in, green for things related to making a copy, red for things you'd need to touch to clear a jam. (If I'm remembering correctly, it's been a while...)

That's not how residential smart switches work. Wire them that way, and the smart system fails every time someone uses the light switch from the wrong entrance to the room. That would violate electrical codes, which require a person to be able to turn on a light as they enter the room regardless of which door they use.

The most readily available, and IMHO best, hardwired residential smart switch in the U.S. is Lutron's Caseta line. When installed to replace a three-way switch, you do one of two things: rewire the other switches on the circuit so they always pass power to the load but also send a signal back to the smart switch over the existing wiring; or replace the other switches with wireless remotes.

The Caseta switches also have a mechanical power disconnect built in, so you can always turn them off. This also lets you disconnect power from the load in a way that can't be overridden remotely. You can reset them that way too, if needed; it's a rare day indeed if so, because they're incredibly reliable. Far more so than, say, Hue bulbs or "smart plugs."

None of which does any good for an industrial lighting setup where each light fixture has an internal smart power switch, controlled via a network. Worse if the light is designed to always reset to "off" after a power outage and can only be turned on from a working controller.

Anyone else remember when Apple claimed (to the govt (FCC?)) that jailbreaking the iphone was going to lead to terrorists taking down the cell network?

The mobile space is a damned mess for users, and that's by design. (nearly) Any other computer that would be otherwise considered multi purpose, allows the owner to separate management functions from daily functions (i.e. admin/root vs unelevated). This phantom menace created in the mobile space is one wholly of teh design of the mobile OS vendors.
