Goodness, we used to write ai bots for UO back in the day and pit them against each other. I can only imagine this has continued. Look at the most heavily hacked online games and I would guess a good deal of the top fights are not between players but scripts. probably more entertaining to watch also.
the roofing materials that are used around here have been used for a long time because they do the job and also are known to me safe for capturing drinking water.
What is the toxicity of this stuff?
we just had our first real summer temps the other day at 42c/107.6f. I would love a cooler house but not if it is going to poison my family.
