He'd written everything from operating systems to end-user applications and had a well-thumbed first printing of Knuth's TAOCP: Vol. 1 and was the person I brought my royalty check (for finding an error and a point of improvement in _Digital Typography_) in to work to show.

Now, now, you can't go criticizing sports teams when the N.F.L. is a non-profit organization which exists for the good of the game and to enhance the beneficial effects which the game has on society, right? I'm sure the goals of the other sports organizations are as noble and that their bookkeeping is similarly transparent.

I'm sure that it's some bizarre, pestilential outside influence which has banned community ownership of teams (save for the grand-fathered-in Greenbay Packers) and required that a minimum percentage of a team be owned by a single individual.

``Almost no one'' != none, therefore, some people are using Haskell in HFT by your own admission.

I cited a source which noted Haskell is used for such --- do you have a citation for that number / proportion being very low?

Looking through the first page of Google search results for ``high frequency trading programming languages'' Haskell is noted as being advantageous for its ability to prove correctness of a program.

Three words:

High frequency trading

Most of the code driving that is written in Haskell, which is just criminal, since it's some very bright people writing that code, and they're not contributing in any meaningful way to humanity, just fiddling bits to determine who has how much of what money at the end of each trade.

Classic old saw is that the only tool in a workshop which can duplicate itself is a lathe --- hence the Gingery books starting w/ making a lathe using investment castings:

(Book 1 is how to set up a charcoal foundry)

Had a copy of Book 2 a long while ago and gave it away --- always rather regretted that.

The Shapeoko 2 works well for milling circuit boards (esp. if one upgrades the spindle):

Precisely adding solder paste should just be a variation on an extruder:

and here's one example of using the machine for pick and place: (using an aquarium pump for vacuum).

The clear one was just scraps and poplar craft boards --- I'd love to do it again w/ a nice piece of maple and wrap the grain all the way around, but the red oak was much cheaper, but I found the grain boring enough that I went for the dark, dark finish (which is more delicate than I was anticipating...).
