A few days later, Chet Ramey posted https://www.tuhs.org/pipermail/tuhs/2024-October/030946.html the link https://www.telecomarchive.com/bstj.html where the Bell System Technical Journal from 1922 to 1996

Dan Halbert explains the origin of the Unix command more(1).

Includes "Linkers and Loaders", which I have seen before, but apparently I had not bookmarked it.

Appears to be an interesting read.

The number of transistors is smaller than I had expected, it will be interesting to compare it with the values for Mailüfterl.

The Language-theoretic approach (LangSec) regards the Internet insecurity epidemic as a consequence of ‘ad hoc’ programming of input handling at all layers of network stacks, and in other kinds of software stacks.  LangSec posits that the only path to trustworthy software that takes untrusted inputs is treating all valid or expected inputs as a formal language, and the respective input-handling routines as a ‘recognizer’ for that language.
The recognition must be feasible, and the recognizer must match the language in required computation power.

DJGPP is a complete 32-bit C/C++ development system for Intel 80386 (and higher) PCs running DOS. It includes ports of many GNU development utilities. The development tools require a 80386 or newer computer to run, as do the programs they produce. In most cases, the programs it produces can be sold commercially without license or royalties.
