*my interpretation assumes a continuously ascending path from the imaginary sea level to the mountain top. I believe it's almost always the case in practice.

A counterexample is a peak within a crater.

I find the definition of the prominence of a mountain peak very interesting:

"The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col."

It's the peak's height minus how much the sea level would have to rise to make this peak the highest on its island.

For intuition, see the examples at https://en.wikipedia.org/wiki/List_of_mountain_peaks_by_prominence

Does anyone understand what Elton John says in the song Sacrifice? It sounds like a made-up tongue to me except for a few phrases here and there.

Years ago, I was in a web company whose business was people search. The biggest takeaway from this particular industry is that people love to find details about others but hate to have their details available to others.

Xu Hongming exhibit at Qualia in Palo Alto. I recommend seeing this in person if you have a chance. It's huge.

Don't read my toots if you're easily offended. My favorite American comedy is Ghost World (2001).

Commenter: It's time to release Gerald* back into the wild where he belongs!
Me: Why don't you release your kids?
Commenter: I don't have kids.
Me: Good for them!

Zut, j'ai fait une couille.

Seriously.

- What does it mean to be intentional with your work?
- It's to show that you're in control. It's an essential component of macho culture.
