One neat thing about solar and wind energy, that might have national security implications in light of recent events, is that it’s really hard to blockade.

I know a couple of math tricks you can do with playing cards.
Give an audience member a pre-sorted deck of cards. Remove any card. Riffle shuffle the deck 3 times (4 if you’re bold). Return the removed card to a random position in the deck. Magician examines the deck and identifies the card.
Audience member selects any 5 cards and hands them the the magician’s beautiful assistant. Assistant examines these cards, and reveals 4 of them, one at a time, to the magician. Magician predicts the 5th card.
Indeed, and would have earned full marks had he said that, or even showed any awareness that his intermediate results were somehow nonstandard.
I had a student tasked with summing a finite geometric sequence with |r|>1, let’s say 1+2+4+8+16. He had apparently forgotten the formula for that, but knew the formula for the infinite series a/(1-r). Good enough he thinks, and sums 1+2+4+… = -1, then subtracts off the excess terms 32+64+128+… = -32, and gets the correct answer of 31.


Jingle bells Jingle bells, Santa Claus is dead // GI Joe the Eskimo shot him in the head.
Row row row your boat, gently down the stream // Throw your teacher overboard and listen to her scream.
Mine eyes have seen the glory of the burning of the school // We have tortured every teacher and we’ve broken every rule.
Chinese, Japanese, Dirty knees, Look at these.


If she’s used all the pieces and solved enough to reverse engineer the shape of all the missing pieces, then it is fully solved. If the missing pieces cannot be individually identified due to shared edges, then it is still solved, but is no longer a 1000 piece puzzle and she should only claim to have solved the 999 or 998 piece subpuzzle.


If you indexed minwage to the local affordable housing costs, there might be more interest in building some.
Yes, I switch between a few OTA stations. Usually just on as background noise. There’s a couple of NPR programs that I sometimes try to listen to.


You shouldn’t kill anyone in private that you wouldn’t kill in public.
You don’t need that sort of instructions, just vague feedback on what’s good and what isn’t is sufficient. Do more stuff like what got good feedback and less stuff like what got bad feedback. Think of it as AI training set and hope you have enough I to learn without the A.
