Minor nit: Page Rank is pretty much spelled out publicly in the patent. I haven't read the implementation code, but I was on the indexing team. I don't think the source / root node(s) of the graph were ever made public, but other than that, the algorithm itself is known.
Ascorer, Amit's Scorer is where the ranking magic happens. My team generated a few of the hundreds/thousands of signals that went into Ascorer. I'm not sure if learn-to-rank is still considered Ascorer, or its replacement. I left before Amit, but seeing the things that came out leading to his departure, I'm sure it's no longer called Ascorer.
(On a side note... what's the word for scratching the name of a disgraced Egyptian pharaoh off a monument? Iconoclasm and ostracization aren't quite the phrase I'm looking for.)

Damnatio memoriae?
> Damnatio memoriae is a modern Latin phrase meaning "condemnation of memory", indicating that a person is to be excluded from official accounts. There are and have been many routes to damnatio memoriae, including the destruction of depictions, the removal of names from inscriptions and documents, and even large-scale rewritings of history. The term can be applied to other instances of official scrubbing; the practice is seen as long ago as the aftermath of the reign of the Egyptian Pharaohs Akhenaten in the 13th century BC, and Hatshepsut in the 14th century BC.

(for example as result of Ever Given I learned plenty of things about container shipping, even if it is not something directly useful - for example this video showing unloading process of container ship is rally interesting: https://www.youtube.com/watch?v=INsf6XHdfAA - shows crane picking up truck-sized containers, dropping them into truck, then immediately following process)

One thing I learned from poking around financial models (I was/am a maintainer for a domain-specific financial modeling language used by a Fortune 500 financial services company) is that some ships are capesize[0], meaning they're too big for either the Panama or Suez canal and must transit Cape Horn and/or Cape Agulhas.
In our language, Booleans are represented as IEEE-754 double-precision floating point numbers (0.0 is False, everything else is true, with the constant True being 1.0), so for a bit I was imagining gigantic container ships dressing up as superheroes and putting on capes, and going to parties out in the middle of the ocean. Digging a bit deeper, I discovered this particular field was being used as a Boolean, and a quick web search ruined the magic of what capesize really meant.
I presume this wound up in our financial models because whether a ship is capesize affects its value, which affects the value of corporate bonds (or other corporate debt instruments) partially backed by ships as collateral. I suppose it's also possible that at some point we entered into bespoke repurchase agreements involving ships. (To avoid various risks in bankruptcy courts, sometimes financing is arranged by selling some asset below market value with an agreement to buy it back at a fixed date at a fixed higher price. There might also be a rental agreement involved. The cash flows look like a secured loan, but in case the loan can't be repaid, a court order isn't necessary to seize assets... the collateral assets have already legally changed hands.)
