It looks like Trevor gained root access to Linus!
Good one! I looked at the thread, and it looks like people's "memory" doesn't go back far enough. The original IBM PC (and later XT and AT), consumer computers do note, did use 9-bit bytes, with a simple parity bit for each 8-bit byte. Many PC clones, though, soon went for 8-bit RAM (no parity) to save costs. ECC on a per byte basis requires 11 bits, but ECC on a much larger block basis is more efficient, with the typical later implementation being 72-bit DRAM providing ECC to 64-bit data. For those who might not know, first level ECC allows single-bit-error detection and correction, and double-bit-error detection. While I'm sure of the validity of this whole thread (and the claims of "why"), it was different in the beginning of the PC era (1980+), where Intel was pretty neutral and IBM applied their mainframe computing robustness principles. BTW, I've always been a parity/ECC fan! Every desktop I ever owned had this protection. As for my current laptops ..... shame!

Ha! Love it!... Of course, it might be the other way around, since Linus says he's been on the ECC bandwagon for decades.
https://www.realworldtech.com/forum/?threadid=198497&curpostid=198647 So many quotable lines... I like this one especially:

Hehe, that's a great read, thanks for that. I'll believe Alberto's take over Gilbert's... :-) I'm glad Linus put pen to paper (bits to the ether?) on this as it will make it a lot easier to convince Linux/FLOSS people to aim for ECC on their boxes. Most will agree that Linus is a Really Smart Guy(TM) and is generally pretty honest/open. He promotes ECC. That will be good enough for many people! I agree 100% with everything Linus says, especially about the history, and Intel's dumb (intentional) moves. I've said it all for years. <feeling vindicated> I'm also glad to see Linus continues his completely non-PC rant-style approach to communication. Wowza! P.S. A lot of the other names on the thread aren't lightweights either. Go AMD! Go ECC! -- a 20-year-Intel-only guy now running a Ryzen 3900X that cost a third of a comparable Intel "workstation" with ECC and full x16 slot
