There are lots of reasons that the insurance company may decide not to pay out. You might be better just putting into a savings account each month.

The one time you accidently leave a window open is the time you will get burgled, and the insurance will just laugh at you.

My tip for insurance is to look through the conditions, implement all the security things they need, and put what you would spend on insurance in a savings account.

Bavaria doesn't count as Germany?

Some people believe that rates of radioactive decay have changed with time, to allow the isotopic abundances that we see to be consistent with a 6000 year old universe and in order to be able to discount any archaeological or palaeontological result they don't like. Showing that nuclear physics was the same 2 billion years ago is unlikely to change their minds.

Here you don't pay any income tax on the first ~£10k/a that you earn. To be paying enough tax to be worth complaining about you must be taking home enough money that I have little sympathy for you.

But maybe some people like spending their life being annoyed about numbers.

Most of your radiation exposure is from the radiation that's been in the rocks for ever and from cosmic rays. Releases from nuclear power are tiny compared. Radiation safety limits are incredibly conservative.

RaspberryPI was designed to be cheap and makes various compromises, e.g. very low end CPU, low memory, USB connected 100MB ethernet, fussy PSU.

Novena looks easily powerful enough for normal use, plus has nice features, FPGA, gigabit network.

UK figures are 5000 deaths per year from traffic pollution vs 1800 from road accidents.

and what do you do about the other 30,000 people killed on US roads each year? (plus many more from the air pollution from vehicles)
