Summer is going later

So right now I am in the Pacific Northwest, where I grew up.
It is currently late August. From what I remember as a child, at the beginning of September, we would get the first hints of chills, mists, and maybe some rain. The past decade or so, it seems that the hot and dry weather has continued through September, and almost into October.

That also makes going outside much harder, as it is still hot. September could be prime adventure time, as it is brisk but still has lots of daylight. But right now, I am still stuck inside, still feeling tired and lazy. And trying to get up and make myself a 50 cent cup of ramen. :/

I woke up this morning and dreamed up the idea of prime polyominoes

I think it was a pretty good discovery for someone trying to get back to sleep after waking up early, but apparently the idea of primality of polyominoes has already been discovered.

Still, good catch!
