Other problems. Never heard of a print train with APL characters for high speed printers. Had to have a special type ball for Selectric typewriters. It wasn't until the late 1970's that teletype matrix terminals started supporting APL characters. Likewise for 3270 monitors.

Yes, cats should never be underestimated! Feline problem solving is powered by evolution, so it had better be effective. My AI text was Philip C. Jackson's Introduction to Artificial Intelligence (1974). Even then we could see that overcoming the challenges were further off than the optimists t

That's because APL required a specific code-page under EBCDIC: https://en.wikipedia.org/wiki/APL_(codepage) . On Wed, Jun 13, 2018 at 12:15 AM, Don Guinn wrote: > My green card showed the EBCDIC character set and it did not include APL > characters. > > On Tue, Jun 12, 2018, 8:37 PM Devon McCorm

If they're using graphics cards as the base, it's not so much like J's arrays, but more a collection of Nx4 matrices. Thanks, -- Raul On Sat, Jun 16, 2018 at 7:29 AM Ian Clark wrote: > > Yet more ways of coming up with "42" in time for yesterday. > > https://www.livescience.com/62827-fastest-su

Yet more ways of coming up with "42" in time for yesterday. https://www.livescience.com/62827-fastest-supercomputer.html If you read the whole article you'll see they could have had a computer with the J primitives as its machine instructions. -
