RIP to a keyboard-era legend
Peter Salus has died
Unix fans mourn a legend as comments turn into a tribute, reading list, and meme fest
TLDR: Peter Salus, the writer behind a beloved book on early computer history, has died. Commenters are mourning him as a legend, swapping reading tips, and even debating whether his most famous book is a must-read classic or more of a shelf reference today.
The big news is simple and sad: Peter Salus has died, and longtime computer history fans are reacting like they just lost one of the people who helped explain their whole world. Salus was best known for A Quarter Century of Unix, a book several commenters describe as essential for understanding how today’s computing world grew out of earlier systems. In plain English: he was one of the storytellers who made a confusing slice of tech history finally make sense.
And the comments? They’re doing what online communities do best: grieving, recommending, joking, and lightly arguing at the same time. One person kept it brutally short with “RIP a goat” — internet shorthand for “one of the greatest ever.” Another said Salus’s book was the first thing that made the messy family tree from old phone-company software to Berkeley’s version to Linux click in their head. That’s the strongest feeling in the thread: this wasn’t just a writer, this was a translator of nerd history.
But there’s also a tiny side plot brewing. One commenter admits they’ve mostly used the book as a reference tool, not a cover-to-cover classic, and openly asks which of Salus’s books still hold up today. That’s not exactly scandal, but it is the thread’s mini-debate: treasured masterpiece or useful archive piece? Meanwhile, someone dropped a Wikipedia link, and another shared an Internet Archive copy while joking that the cover looked hilariously “redacted.” Sad news, yes — but the community turned it into a heartfelt, slightly chaotic group memorial with book-club energy.
