Rider movement is eliminated by calculating the second integral from the acceleration. That gives you the difference in location. You then average the position over a couple of seconds (as an filter for the user movement) and then you compare it with different possible tracks. The track that has the highest match score wins.
If you have multiple possible tracks you use the average data of multiple days to get a better accuracy for daily commutes. The right track will next to always increase in score.

To me the hardest part would be the comparison of the track and the relative position data, and that is only hard to me because right now I don't feel like spending an hour of googling on how to do it because it is a solved problem.

If I wanted to go to to Mars I would strongly prefer to die AFTER I was able to build a working colony there.
Identifying and countering the dangers helps to get some productive years out of your astronauts. The fact that many would go on a one way trip there does not mean that most of those would like to die soon there. I hazard a guess that most would like to live a lifetime there.

Side slots suck because people tend to forget to unmount the card, with data integrity issues as a result. With the card behind the battery this is not an issue.

That is a similar problem to the one with some of the modern baby monitors.

They better watch out,
They better not cry,
They better not pout,
I'm telling you why:
Google Bear is coming to town!

He's making their list,
And checking it twice,
Gonna find out who's paying the most.
Google Bear is coming to town!
He sees you when they're sleeping,
He knows when they're awake.
He knows what adds you buy,
So pay up for goodness sake!

That is not how it's done here it the Netherlands.
I imagine that tool will be outdated for rubber spacers with this type of concrete.

Indeed, load balancing and shifting is not new. It is, however, important and Google needs it to get maximum profitability out of their servers. To do so people need to know that it exists.

Google did not claim there had not been other systems with similar load balancing. They simply explained what it was and how to use it. You know, the data you need to know if it is applicable to you.

An intelligent AC would already have cooled the house. As a house needs to be well insulated and ventilated with a heat exchanger anyway the heat will not take over too soon.

I live in an apartment and I dry my clothes in the air. My apartment is well ventilated (with a heat exchanger) and thus the moisture won't build up inside.
When I lived in a place where I could dry my clothes outside I did so in the summer. It requires a little more planning and you need to check the weather forecast before you wash. If it's gonna rain you either do not wash or you dry the clothes inside.
Bird poop wasn't an issue, even though we had gorgeous flocks of sparrows over our garden. I can remember a few instances but I'd throw the item back in the wash and the next time I did that type of laundry it would come out clean again.

Just don't dry your clothes in a spot where you wouldn't park your car due to bird poop, like under a tree. Drying goes faster in the sun anyway.

No of course you are not going to get up at 3AM to do laundry. You would fill the washer at night and it would keep tabs on the electricity rates, running when it gets below a certain price (or when it's getting late and the wash needs to start to get it done before you want to take it out).

Yes. I do that often. I am not sitting there waiting till the washer is finally done. I do something else, like working or sleeping.

That rarely happens and does not harm the clothes. If it would happen often or would harm the clothes I would simply set a calendar item to warn me to get it out.

No. I heat my shower water with natural gas. Gas has little storage issues.
If I would use electricity for that and prices would be flexible then I would switch to a water heater with tank that would heat the water when it's cheap to do so, assuming the energy loss due to cooling would not surpass the gains from the time shift.

Another solution is the freezer and the airco. Both can run max at the moment the electricity is required, since both appliances are meant for uses that can handle a couple of degrees delta. Set some limits to them and they would run mostly when the power is cheap.
Electric cars: Most electric cars only need to charge a few hours a night. If you set it so it charges when electricity is cheap then the charging is cheap.

Large users are even more important. Aluminium is a gorgeous metal for it's near infinite ability to be recycled, but initial production requires massive amounts of electricity. A supply following aluminium plant would save a lot.
Same with a water desalination plant.

That's not another issue. It's exactly the same issue.
Storage does not work (yet). It's simply too much energy in a too impractical form. The load partially following the supply would reduce the need for storage. Not eliminate it, reduce it.

Nah, for maximum power you pay Henry Winkler to move to the politicans and harvest energy from the delta caused by his coolness and the hot air from the politicians. We could power the world!

If you don't mean memory effect then don't use that term.

Most drugs are quite large molecules and not UV resistant. If it becomes a problem then we, in the Netherlands, will start installing UV installations after our sewage treatment plants. For now it is only done in large hospitals because there the medicine concentration is significantly higher. There are monitoring systems in place to test for drugs in the cleaned water after the sewage water treatment but the need to clean them out of there is just not all that big.

If continuous sampling proves it confirms to both these standards it is safe.
Seriously. Any decent muncipal water supply in the Netherlands continously monitors not only for baterial cultures but also PH and various chemical concentrations. If a test fails there is a major problem. I haven't had any trouble with our water (all toilet to tap) in my 30 years. The problems I heard of were things like broken pipes where mud got into the water. That'll give you bacteria.

UV and/or ozone treatment destroys them quite well. And you really don't have to kill them all. It's quite easy to make em cleaner than the aquifer water (which is recycled dinosaur pee).
