Talk:1755: Old Days
The "4-6 weeks" thing might be a reference to high-performance computing, in particular scientific calculations, a few decades back. From what I've heard from older people in my scientific field (I'm too young to have experienced it myself), you'd prepare your program on punch cards, mail these to an institution owning a fast computer (because your group or university didn't have one), and they'd run the program and mail the result back to you. This, I've been told, took a few weeks. Maybe someone with first-hand experience can give more information. 141.101.104.98 10:34, 4 November 2016 (UTC)
- Reflections on Trusting Trust
Reflections on Trusting Trust (pdf), Ken Thompson's acceptance speech for the 1984 Turing Award, in which he discusses creating a backdoor in the C compiler (yes, there was only 1 when he invented the language) that itself creates a second backdoor in the login program when it is compiled. Additionally, it reproduces itself when compiling the C compiler from un-tampered-with source code, so that anyone using the binary (compiled) compiler would be unable to avoid reproducing the backdoor in all its forms. This is the sort of thing that gives security programmers nightmares. 108.162.221.168 04:52, 4 November 2016 (UTC) (bonsaiviking)
