- One of the strangest weather days I’ve seen. Dropped from 50 to 10 degF over the course of 6hrs.
- Spent the day doing a bunch of stochastic modeling.
- The word for “females and males being separate” is dioecious. The opposite is hermaphroditic, where a single animal can have both the male and female reproductive organs.
- Urchins are dioecious (although it’s very difficult to tell if you have a male or female).
- The females expel a cloud of eggs into the water, and then the males release a cloud of sperm once triggered by the eggs. I think the eggs have a slight orange tinge, and the males are more white? Both AFAIK both look like visible milky substances.
- I saw this happen for the first time today! Both of the urchins got within a couple inches of one another (black longspines are ~6” long, so I thought they were fighting in their entanglement). One of them released ~8 waves of the milky fluid. Didn’t see any activity from the other. Could both be male, could both be female, could have had unreciprocated reproduction, or the 4th permutation: I may have observed fertilization! Will check for baby urchins, should occur within a week or two if any eggs get fertilized -> drop -> hatch.
- YouTube has a clip feature. You can loop 5-60sec of a longer video (and permalink it).
- Tournament styles: Round robin is where you play everyone else. Swiss is where you play people at a similar performance through the tournament (do well, play better opponents).
- Common tiebreak is Buchholz, which is the strength of the opponents. Add up all your opponents points. If higher, you had a harder tournament, and you win the tiebreak. Sometimes discarding the top and bottom scores. Useful in swiss.
- Remember (oversimplified): Scylla is the C++ version of Cassandra, which is Java.
- Of all the spices you can blacken on salmon, cumin has to be one of my favorites.
- Summary of a fixed term loan and its amortization schedule. How to calculate the total monthly payment (bottom first), and then what portion of that monthly payment goes toward principal vs interest (top equation).
- LoC interest payment is just average daily balance against your interest rate. If you pay monthly, just simplifies to draw for that month * interest. But daily interest calculation is better if you plan to pay it down more than once a month.
- LOTS of private work. Most productive day in a while.
