If you're interested, it appears practical to calculate a 10000-row triangle in about 10 seconds in Dyalog APL using a simple convolution algorithm, as long as you have enough virtual memory. Peter, First, let me apologize for not getting back to you sooner. I spent a few days running around New ...

His name is Trippier! What did you expect?? Should have remained a red card!

Some Chromebooks run low-end Intel processors, some Chromebooks run Qualcomm processors, some Chromebooks run realtek processors. Is there a preferred processor? Does using one kind of processor rather than the other make for a more seamless Unix/ride experience? I ask only because I made the ...

Isn't the overstrike of a "St Andrews cross multiply" inscribed within a circle the traditional symbol for Kronecker product, and wouldn't that be confusing if APL used it for something else?
