We ended up just opening up the windows to let the house warm up to a nice temperature. It's such a waste that the air conditioner keeps trying to cool the whole city to 20C, but dad pays the bills so that's his problem.

People do this because they don't trust/understand the controller - especially understanding the amount of time it takes to respond to a setpoint change.

Back when A/C was simple, it would just run flat-out until it reached the setpoint, and then turn off until the hysteresis bound was crossed. But then they added inverters and the A/C might run an lower powers when it thought that might be a good thing: but sometimes gets it wrong. The solution was for the human to override it by setting a stupid setpoint so the stupid smart A/C might actually do what they want.

Adding extra layers of complexity to the thermostat may overcome the A/C controller limitations, but on the other hand might just make it so unpredictable that people want to override it more.

The article says they asked 2000 children, but there's no mention of what bias may have affected the sample of children that they asked. They may have mainly asked older children in that range, which would have skewed the results greatly, compared to evenly sampling across the age range.

The "as young as four" remark demonstrates that there were no 0, 1, 2 or 3 year-olds who owned their own phones, which would account for 800 out of 2000 evenly sampled children. That means among the 1200 4 year olds and up there must be 667 with phones, ie. 56%. Further assuming the proportion increases with age, at 9 years old it would be much higher than that.

What if you can point your smatphone at the t-shirt you like, and it identifies an online merchant selling it direct out of China for 1/10th the price, shipped to your home? No worries haggling with French salespeople, no having to carry it around for the rest of the day, and no bloated luggage. Maybe with a licensing deal, the brick and mortar store could even get a cut out of it, and not have to worry so much about inventory.

Comment Re:Fuel tax? (Score 1) 500

Is there "good" and "bad" mileage? If it's about road wear, then pavement damage goes with something like the cube or more of weight, so the truck is likely to do more road damage per litre of fuel used than little Johnny's car. If it's about traffic congestion, trucks also slow traffic flow. If it's about CO2 emissions, then emitting 1kg of CO2 from the car taking Johnny to school worse than causing 1kg of CO2 to be emitted from getting stuff delivered?
