I recently diffed Unix 10 and NetBSD to see if or how many common actual byte-for-byte original code I could find. I found some.

Of course, because if you have two similar applications, some of the code will likely be the same if the codebase is large enough.

Yes it’s due to architecture. Apparently because of the 4.4BSD-Lite lineage it wouldn’t possess the original source with those exceptions.

Man, imagine a 2.5k line kernel. You could probably fully understand how part of the computer works.

2.5 lines of J, K, or some other APL-family language?

Do you know about half button presses?

An A press is an A press. You can't say it's only a half

I can’t remember which generation of console it was, but IIRC some video game controllers made a big deal of their special buttons that could tell the difference between partial and full presses.

This lead to the phrase “pressure sensitive buttons” being bandied about, which is kind of funny (what is a pressure insensitive button? An immobile lump I guess).
