Robinia are taking over unmaintained areas like construction grounds and the edge of the forrest. Some in the forest are full size.What can I do against them spreading?
Like imagine you're swimming a few hundred metres from the beach and your partner gets a cramp, do you just say "oh well you knew the risks" and leave them?
A friend told me his lifeguard course contained a self defense portion, to avoid being dragged underwater by someone panicking. I can't say the same about my mountaineering experience.
If you are willing to go all unhinged, you can do what I do with my cocoa powder.I fill a jar 3/4 with milk, add the powder close it and shake vigorously.
That's not my main point as I don't think the heat capacity of food is so important over the long term.
I mean, that the inevitable inefficiency of the fridge in a closed system, is no different, that any other device consuming the same amount of energy, as it all ends as waste heat.
An indoor refrigerator in the winter is essentially a resistive heater. It's not nearly as good as a heat pump, but may be better for the environment that burning gas, depending on the local electricity mix.
The test suite probably looks something like this:
int tests_passed=0; int tests_failed=0; for(int i=0;i<100000;i++){ printf("test no. %d: ", i); if(is_prime(i)==actually_is_prime(i)){ printf("passed\n"); tests_passed++; }else{ printf("failed\n"); tests_failed++; } } //...
