Me too, was thinking about creating simple web app. for myself. Purely from the view of food wastage. I live alone and it's pretty difficult sometimes being able to plan meals when some food packs don't last. Freezable things are OK, but sometimes the salad goes in the bin. Tracking these things avoids purchasing any unnecessary items from the shop. Will check this out.
I think nuclear power is a quick win, for the amount of CO2 discharged and the 'amount' of materials gained. The lasting legacy will always be the cost of maintenance, both in knowledge (in 100 years from now will people be able to operate the reactors and remember where all of the crud was left) and environmental impact. Certainly in the north sea area of europe, there is a drive for wind power, which I fully back. Nuclear power plants don't run themselves, which is why it's a highly skilled area, kill the skill, welcome to long periods of radiated land masses which are not obvious (unless you have a geiger counter)
I could balance equations in chemistry and do some algebra and trigonometry at GCSE level. But this blows my mind. Higher tier GCSE Maths. I should have paid more attention. I think I know of what regression is in a simpistic term. It's like taking a rolling graph and predicting the next point on the x / y axis, using the previous data as a training model. I hope.
