He also doesn't get that even at a local level things like AC compressors are already averaged out and that delaying the timing of starts really makes almost no difference at the neighborhood level, much less a town level.

Averaged-out appliances are what you want with baseload generation. With fluctuating renewables, you want to be able to delay a significant fraction of appliances at the same time, for short periods when the generation is low, and start a significant fraction of appliances at the same time when generation is high. To do this, the appliances have to somehow receive a signal of when to start and when not to start, such as a price signal or a direct control signal from a utility. Users would still be able to have control, but could save money by sacrificing some control.

Comment They're missing a lot of emissions (Score 1) 409

I notice that only gas is listed as adding new emissions. But hydro has methane emissions from the vegetation that's flooded when the dam is constructed. Not to mention the concrete that makes the dam. Solar, wind, and nuclear also have some building emissions costs, unless you replace all construction vehicles with electric and find a way to make concrete and steel without carbon emissions. (Wood might be an alternative for certain parts of wind turbines and maybe even solar frameworks.) Gas should probably have much higher emissions too, as the whole infrastructure from the well to the power station leaks methane. (How much is debated, but it's not zero.)

I use GVim all the time. It can "highlight syntax and auto-indent code...spellcheck documents... [and] record macros". I don't see the point of managing code snippets - if you're using the same code multiple places you should take a DRY-er approach. And being an IDE is for Emacs people. ;P

The moon is much closer to Earth than Mars. It's so close that we can pilot vehicles on the moon manually, like an RC car, with just a two-second delay. Vehicles on Mars need to be a lot smarter.

That said, Opportunity is really slow. Its top speed is 50 mm/s, or .1 MPH. I think Curiosity is actually slower. Maybe one of these private space ventures like Elon Musk's SpaceX can send up a fast (minimum 5 MPH or 2,200 mm/s) rover that just drives and takes pretty pictures.

Comment How similar is your AI boss to the fictional Manna (Score 2) 71

Dr. Chun,

Have you read a short story about an AI boss called Manna? (I'll include relevant quotes if you don't have time.) How does your system for the Hong Kong subway compare? It's clearly similar to your subway system in some ways:

At any given moment Manna had a list of things that it needed to do.... Manna kept track of the hundreds of tasks that needed to get done, and assigned each task to an employee one at a time.

But does it micro-manage tasks like Manna?

Manna told employees what to do simply by talking to them. Employees each put on a headset when they punched in. Manna had a voice synthesizer, and with its synthesized voice Manna told everyone exactly what to do through their headsets. Constantly. Manna micro-managed minimum wage employees to create perfect performance.

Does it record employee performance metrics and report them to (upper) management like Manna?

Version 4.0 of Manna was also the first version to enforce average task times, and that was even worse. Manna would ask you to clean the restrooms. But now Manna had industry-average times for restroom cleaning stored in the software, as well as "target times". If it took you too long to mop the floor or clean the sinks, Manna would say to you, "lagging". When you said, "OK" to mark task completion for Manna, Manna would say, "Your time was 4 minutes 10 seconds. Industry average time is 3 minutes 30 seconds. Please focus on each task." Anyone who lagged consistently was fired.

And how have employees reacted to their AI boss - if, in fact, you have been able to get honest evaluations from employees?

Raised again.

The initial plan called for a ditch and wall with 80 small gated milecastle fortlets, one placed every Roman mile, holding a few dozen troops each, and pairs of evenly spaced intermediate turrets used for observation and signalling.

And more details on another page:

Each tower was in sight of the next in the line, and a simple system of semaphore signalling was used between them.
