Efficiency

A few days ago I saw someone say that they will never use self-checkout because they don’t want to do someone else’s job, and they want to be paid for the act, if they were to self-checkout. In New York, recently, there was talk of a ten percent discount for people who checkout by themselves, rather than use a cash register.

For me, the beauty of self-checkout is that the time you spend in food shops is finding the food and other things, and then within thirty seconds paying for everything without queuing. At Décathlon as well self-checkout works extremely well. You pick up some stuff, dump it in the “bin” and it recognises the RFID codes, and shows how much you owe. Within a few more seconds you’ve paid, and you can leave. The more you do it the more fluid the action becomes.

When winters were long and cold Minergie seemed like a fantastic idea. They would turn a home into a thermos, blocking all heat loss to save on energy costs and more. Minergie does work extremely well in capturing and holding on to heat, from the sun, washing machine, dish washer and more. You might think “But those aren’t heaters” and you’d be right.

During a heatwave the Minergie thermos has a serious flaw and that is that it requires open windows. Open windows in theory, and practice are easy. Wake up, open the windows, and once outside is warmer than inside close them. Then you keep the ambient temperature low and comfortable.

Imagine that you’re out for a walk. You’re looking at the landscape and taking photos with your camera or phone. At the same time your GPS watch, or phone app is recording your location every second. What remains of the walk is a gps track that has a resolution of one set of gps co-ordinates per second, and photos when you took photos. Most of the walk is “lost” because to record video of the entire walk would be too consuming.

When you plan road works that are meant to improve journeys for people cycling, and on foot, it is essential to remember that people who are on foot, or on bikes, need proper infrastructure to get from A to B, because if they don’t, then they go from being on foot or on bikes, to being in a car. If we take this to the extreme, if you don’t plan for pedestrians, or cyclists, or cars, then people just stop visiting.

One of the weaknesses of Electric cars is that they take longer to refuel than a petrol burning car. One of the advantages of electric cars is that they take longer to refuel than a petrol burning car. For some people this is a deal breaker. They don’t want to be forced to wait from two to 12 hours for their car to charge. I think that this could be a strength of electric cars.

While I was cat sitting I spent time playing with a Roomba. Most people set the roomba, and let it clean. I don’t. I watch it and I observe how it works, how it goes from place to place and how it navigates, and gets trapped, and procrastinates in one corner or part of an apartment/studio. Roombas are glamourised but I think they are flawed.

Their flaw is that they start from their dock, back and go beep beep beep beep, then they rotate and they start cleaning. So far so good. The issue comes when they hit an object. They start from the top right of a room and they go diagonally to the other side of the room and they hit an object and they turn right.
