He's updating one pump at a time. What are the other pumps doing? Dispensing gasoline... They would not want to just shut everything down and eliminate a half-hour's worth of revenue from 15 pumps just so OP is not inconvenienced.

If you are correct that all the other pumps are in use, then shutting down one pump at a time will result in the same amount of lost revenue (8 pump-hour's worth) as shutting them all down at the same time.

A better solution is to raise the price of gasoline slightly so fewer than 16 pumps are in use at a time. This way, a financial optimum can be achieved between lost pump revenue and the cost of the technician's time.

Another advantage of tolling is that variable express tolling permanently (yes, permanently) eliminates traffic congestion, without overcharging anyone (where "overcharge" means "charge more than the market equilibrium rate").

And another advantage is that it therefore permanently eliminates the need to widen roads to eliminate congestion, which saves taxpayers a lot of money.

So if you don't like paying taxes or if you don't like sitting in traffic, you should welcome variable express tolling with open arms.


Microwave Comms Betwen Population Centers Could Be Key To Easing Internet Bottlenecks 221

itwbennett writes: Researchers from the University of Illinois at Urbana-Champaign and Duke University recently looked at the main causes of Internet latency and what it would take to achieve speed-of-light performance. The first part of the paper, titled Towards a Speed of Light Internet, is devoted to finding out where the slowdowns are coming from. They found that the bulk of the delay comes from the latency of the underlying infrastructure, which works in a multiplicative way by affecting each step in the request. The second part of the paper proposes what turns out to be a relatively cheap and potentially doable solution to bring Internet speeds close to the speed of light for the vast majority of us. The authors propose creating a network that would connect major population centers using microwave networks.

Problem is, you'd end up screwing over the poor - that is, all the people who cannot afford a Prius or similar hybrid/electric vehicle.

Don't the poor usually walk, ride bikes, and take mass transit? Did you know that the poor love tolls more than other income classes because tolls displace taxes the poor would otherwise have to pay?

It would also jack up the price of nearly anything that is transported over the roads...

Actually, what jacks up the price is when we don't charge users full price for use of the roads, leading to a distorted, inefficient market for transportation.

The Chinese don't really know very much about rice. That's why the purpose of other dishes in Chinese cuisine is to help the rice go down.

The Japanese are the real rice connoisseurs. In Japanese cuisine, rice is a thing of worship, probably as an artifact of the Shinto religion where everything has a soul. A Japanese person will tell you that their domestic rice is the best, followed by California rice. But to the Chinese, rice is rice.
