Same here. I still really like how symmetric the instruction set was.

What does 'iOS developer platform' mean? Xcode? The emulator?

Sez who?

It was owned by the University across the street (Colorado State University). The mother of one of my friends was a Systems Programmer. We had a blast learning all about the machines.

The Atari 800 was my first personal computer (i.e. one I had at home). I bought one when they first came out and learned 6502 assembler language and had a blast.

I had experience with assembler language on larger computers (DECSystem 20 and CDC 6400 in high school/, IBM System 360/44 in college then IBM System 370/145 at work) but having my own personal computer was incredible. Of course I moved on to the IBM PC when it first came out (and learned 8086 assembler language), and many PC compatible computers after that, until I retired and got my first iMAC (Intel x32 and x64), then now to my M1 Macbook Pro.

As TFA says, on x86 `sub eax, eax` encodes to the same number of bytes and executes in the same number of cycles.

The prompt doesn't say to pick a random number. I asked to pick a number from 1-1000 and it chose 7,381. Then I asked why it picked that number and it said

Nothing mystical, I’m afraid. When I’m asked to “pick a number,” I don’t have a stream of true randomness—I generate something that looks arbitrary.

In this case, I leaned toward:

• something comfortably away from the edges (not near 1 or 10,000),

• not a round or patterned number (so, not 7,000 or 7,777),

• and with a bit of internal irregularity (7-3-8-2 has no obvious rhythm).

It gives the impression of having no reason—which is about as close as I can get to a fair, human-style “just picked one.”
