Maybe that's my missing link for https://news.ycombinator.com/item?id=48619191 You probably know this, but this is one way to generalize beyond 2D https://en.wikipedia.org/wiki/Angle_bisector_theor

There was only the need for the point on the bisector (on the unit circle). There was no need for the magnitude of the angle. The only thing that needed care was which sign of the sqrt bisects the internal angle as opposed to the externa

I agree with you on three dimensional vector products. It's too special, too cute and doesn't generalize to all dimensions, and as you said, you have to keep track of the two types of vectors. On complex multiplications though, I

Yeah you can have a lighter work desk that way. You bring in the heavy tools later.

I get why it is interesting and useful to write complex numbers in '+' notation rather than the conventional way to denote a 2d vector, like a tuple of components. The benefit is that multiplication and distributive property is a

An well established alternative to compare against would be Stellarium mobile version. Stellarium mobile version is an app, not a web page and the best way to get it is indeed through play/app store. I don't think any of those are

Why the hell not ? I still learn a lot from wikipedia. Maybe it's not useful for those who are experts in every thing. I am not one of them.

I have a different view about checking for NULL. I would suggest you keep checking for NULLs. It's a good habit to have to watch over details and to remain cognizant of edge cases. There are tools of course but they are neither standar

I know. That's human fear kicking in and it makes it worse. Try it once, success brings confidence. Your own anxiety around dogs might be making things worse for you. If you search you will find that holding ground is the way to deal w

Neat way to validate. Your method of sampling could be improved further, unfortunately at the expense of ease of use. If the dictionary was sorted according to difficulty, then you could use stratified sampling. I comment on the related asp

In addition to how much fun it was, it has potential pedagogic value for teaching sampling based estimation. It would have paired well with an exposition of vanilla Monte Carlo and the benefits of stratified sampling. Although stratified sa

I sort of agree with its assesment. Recency bias is a bit strong. It did suddenly worsen though. I was checking if it's assesment was deterministic or not.
