The Unix Magic poster, annotated (updated)
This is a site that maps the references on Gary Overacre's 1980s UNIX Magic poster to short write-ups with sources. I posted an earlier version about a year ago [1]. Since then I rewrote some of the annotations, added deep-linking to individual markers and a frame/sidebar view, gave the site a terminal-style redesign, and fixed historical inaccuracies (daemon etymology, nroff origin, B language vs. Multics, etc.). Contributions and comments welcome; each marker is a GitHub issue. site: https://unixmagic.net [1] https://news.ycombinator.com/item?id=43019136

Capturing all the details of the classic Usenix Unix poster. - drio/unixmagic
A Hugo pipeline that catalogues and annotates every reference on the classic USENIX UNIX Magic poster. The goal is a structured way to explore and understand each element of the poster — part reference, part love letter to early Unix. The UNIX Magic poster was created by Gary Overacre and published by UniTech Software, Inc. in the 1980s. Contributions welcome. When adding an annotation, remember this is a chance to dig into the history behind what you're describing. Share what the component means to you, but also frame the explanation in the context of Unix's early days: how did this functionality compare to other systems at the time? What made it special? This project isn't just about…from github.com

Mapping the Unix Magic Poster – An Interactive Annotation Project2025 · drio.github.io · ▲77Hi HN, We've discussed the Unix Magic poster before (https://news.ycombinator.com/item?id=27029196). Like many of you, I love this poster and all the Unix references hidden in it. I built this as a static site that lets us annotate the Unix Magic poster by placing markers on references and adding descriptions to explain them. I've added a few so far, but there's much more to document. What I love about this approach is that contributions happen not just on the site itself but also through PRs, where we can discuss and refine the details of each reference. Feel free to send a…

- IWI wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲252
The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
