1. Core memory’s radiation resistance and non‑volatility made it ideal for space‑flight computers
- “Core memory is very resistant to radiation. When the Shuttle computers were upgraded to semiconductor memory, radiation became an issue. The solution was to add six extra bits of storage to each word and use ECC… The computer could encounter 100 bit flips per flight…” — kens
- “It works exactly like core memory – data still intact after power resets.” — iberator (referring to FRAM)
2. Modern ferroelectric RAM (FRAM) is seen as a practical drop‑in replacement for legacy battery‑backed SRAM
- “FRAM is a somewhat common retrofit for battery‑backed SRAM: https://bastelblog.runlevel3.de/en/restore/ds1250-fram-replacement/” — userbinator
- “I've already written articles about the French computer and FRAM; enjoy :-)” — kens (linking to his FRAM write‑ups)
3. Fault‑tolerant designs (N‑modular redundancy) are being revived for LLM‑generated code, echoing space‑computing practices
- “I'm betting we'll see N‑modular redundancy systems soon, with an ultra‑hardened, minimal part picking the majority votes of N LLM‑written implementations…” — TacticalCoder
- “This all rests on the assumption that design errors are independent between LLM‑generated programs for the same specification. That's not true for humans…” — kqr (questioning the assumption but acknowledging the concept)
