Interesting historical piece from George Forsythe: http://i.stanford.edu/pub/cstr/reports/cs/tr/66/40/CS-TR-66-...

That was weird: an hour ago I was reading "Version Control with Git" about merging and thinking "Hey, this is all just category theory", I then have a look at HN, and see this.

Nice compendium of results. I hope the misspelling of "Isaac Newton" doesn't indicate errors elsewhere.

Heidegger doesn't seem too far from the mark, judging by Andy Clark's 1997 "Being There": http://www2.econ.iastate.edu/tesfatsi/BeingThere.AClark1998.... The title even seems to be…

Or Heidegger, 'being-in-the-world-with-others' & all that.

Don't forget the Calkin-Wilf tree: http://www.cs.nott.ac.uk/~psarb2/MPC/RecountingRationalsTwic...

Nice. An interesting challenge for someone on Shadertoy.

"foo" occurs in the lyrics to Cab Calloway's 1939 Jumpin' Jive, as in this clip, also featuring fabulous tap dancing from the Nicholas Brothers: https://www.youtube.com/watch?v=_8y…

I should add that I have no affiliation with mathsgear, in fact, I was unaware of their existence until just now. They seem to have lots of nice stuff: https://mathsgear.co.uk/coll…

Just has to be face-transitive or isohedral for dice: https://en.wikipedia.org/wiki/Isohedral_figure For example: https://mathsgear.co.uk/products/d120-dice

Continued fraction approximations p/q have |x-p/q| < 1/q²

Roger Zelazny? He gives an amusing account of him and Delany signing each others books here: http://www.tor.com/2016/05/26/a-few-more-words-from-roger-ze...

And in 3 dimensions it's points and planes that are dual - and finding the line between two points or the common line of two planes can now be done in a similar way, but using Plüc…

The Universe is two's complement. Item 154 of HAKMEM: http://catb.org/jargon/html/H/HAKMEM.html

Pi is ARM of course, but +1 for AVR. 6809 was nice too.

I'd have thought AVR assembler was a better choice these days - a nice orthogonal 8-bit RISC architecture, and you can use gcc, gas etc. (as well as being able to run your code on …

Well, the optimizations are pretty smart to be sure, the stupid thing is that anything over 12! overflows (as GlitchMr points out). I'd like to know how the recursion to iteration …

A simple recursive factorial function: https://godbolt.org/g/97dUFg Not sure if that's smart or stupid.

I assume you mean Jim Norton (and Marcella Riordan): https://www.youtube.com/watch?v=k-apGqB98RI

There is a rather fine (abridged) audio book of Finnegans Wake by Jim Norton (Bishop Brennan in Father Ted), some of which is on Youtube: https://www.youtube.com/watch?v=5Ks60VrtJ4…

It took quite a while for Lisp to get "proper" lexical closures - not until Scheme & CL in the 1980s really, see, for example: http://www.paulgraham.com/thist.html

..as well as "Structured Programming with go to Statements".

The "premature optimization" quote is from Knuth's Turing Award lecture: http://delivery.acm.org/10.1145/370000/361612/a1974-knuth.pd... "The real problem is that programmers have …

Years ago I worked on an SML parser that used LR tables, on errors (ie. with no valid transition) it would try to find a symbol to insert/delete/modify that would allow parsing to …
