Is there a standard notation for the product of all even numbers up to N and for the product of all odd numbers up to N? I know if N is even then the product of evens is = (N/2)! * 2^(N/2) so I guess notation for that is a little redundant, but there is no simple formula for the product of the odd numbers.

N!! is pretty standard I think.

How many evaluations of the underlying function does it make? (Hoping someone will fire up their R interpreter and find out.)

Or, probably, dnorm is a probability distribution which includes a likeliness function, and a cumulative likeliness function, etc. I bet it doesn't work on arbitrary functions.

R integrate is just a wrapper around quadpack. It works with arbitrary functions, but arguably dnorm is pretty well behaved.

Also Cassandra, RocksDB, zstd, Open Compute and probably a bunch I'm forgetting. Meta has one of the most stellar open source contributions of any company.

Zstd already existed before Yann Collet joined Facebook.

That title would probably go to Zucc after the most recent set of earnings. But the previous title holder was none other than Mr. Cyber Hornets himself, the man who just about popped the Dot Com bubble - Michael Saylor.

Saylor lost $6B in a single day (and $10B in 2 weeks) after reporting that his firm had cooked the books in 2000 and his 1999 profit was actually a loss. This was the largest single-day decline in history at the time. [1]

He was fined $8.2M banned from running a public company (just kidding, of course). [2] You'll never imagine what line of work he got into next.

[edit] $6B in 2000 dollars is ~$10.38B in 2022 dollars, and similarly the $10B over 2 weeks would be ~17.31B adjusting for inflation. So it looks like Mr Cyber Hornets still gets to slide in at number two.

Bill Hwang of the Archegos blow up has got to be up there too. He lost 20bn in a couple of days.

>tax combined with a 50% income tax

Properly managed capital gains are taxed at ~15% or less. One should hope that by the time you accrue $50 million your capital gains are properly managed.

How do you get to your 15%? Long term capital gains in the US are taxed at 20% + 3.8% net income tax + state tax. In a city like New York, you're talking close to 40% depending on your tax bracket.

F# is not a superset of OCaml. There are many things in OCaml that are not in F#. The second link you pointed out lists them.
