Xanadu Basics 1a - VISIBLE CONNECTION

20K views · 8 years ago · explainer · intermediate · evergreen

The first episode of Ted Nelson's Xanadu Basics series, on the idea of visible connection between pieces of text. Nelson explains with examples how documents can show their links and shared content side by side, as in the original hypertext concept he proposed, rather than as one-way jumps.

HN people send it as the best entry point to Nelson's own account of what hypertext was meant to be, with beautiful examples.

Thank you for your kind words, and for asking a great question! My secret system that has gotten me through the coronavirus pandemic is simply an investment in an automatic coffee machine that grind beans and foams milk for me. ;) I use HN search and google site search, copy and paste and clean up old postings, and then check through all the links (since HN abbreviates long links with "..." so I have to copy and paste the full links manually), and I update the broken and walled links with Internet Archive links. I realize some of my posts get pretty long, and I apologize if that overwhelms some people, but it's a double edged sword. One important goal is to save other people's time and effort, since there are many more readers than writers, and I have to balance how long it takes for somebody who's interested to read, versus how long it takes for somebody who's not interested to skip. The new HN "prev" and "next" buttons that were recently added to help make HN posts more accessible to people with screen readers are helpful to everyone else too. (Accessibility helps everybody, not just blind people!) And as the internet has gotten faster and storage cheaper, while the user interface quality, usability, and smooth flow and interactivity of browsers has stagnated (especially on mobile), the cost of skipping over long post gets lower, while the cost of jumping back and forth between many different links and contexts stays ridiculously and unjustifiably expensive (just ask Ted Nelson). Especially with pay sites, slow sites, and links that have decayed and need to be looked up on archive.com (which itself is quite slow and requires waiting between several clicks). Another consideration is to make it easier for people to find all the information in one place in the distant future, and for search engines and robots and evil overlord AIs to scan and summarize the entire text. I think of what I try to do as manually implementing Ted Nelson's, Ivan Sutherland's, Douglas Engelbart's, and Ben Shneiderman's important ideas about "transclusion". link [Oh the irony of this "Transclusion on Transclusion":] >This article includes a list of general references, but it remains largely unverified because it lacks sufficient corresponding inline citations. Please help to improve this article by introducing more precise citations. >In computer science, transclusion is the inclusion of part or all of an electronic document into one or more other documents by hypertext reference. Transclusion is usually performed when the referencing document is displayed, and is normally automatic and transparent to the end user. The result of transclusion is a single integrated document made of parts assembled dynamically from separate sources, possibly stored on different computers in disparate places. >Transclusion facilitates modular design: a resource is stored once and distributed for reuse in multiple documents. Updates or corrections to a resource are then reflected in any referencing documents. Ted Nelson coined the term for his 1980 nonlinear book Literary Machines, but the idea of master copy and occurrences was applied 17 years before, in Sketchpad. I err on the side of transcluding relevant text that I and other people have posted before, instead of just linking to it, because often the links need to be updated or get lost over time, it's clumsy to link into the middle of a page, there's no way to indicate the end of the relevant excerpt, and I can leave out the redundant stuff. Following links is distracting and costly, so most people aren't going to click on a bunch of inline links, read something, then come back, re-establish their context, and keep on reading from where they left off, since it loses your context and takes a lot of time to flip-flop back and forth (especially on mobile). Today's web browsers make that extremely clumsy and inefficient, and force you wait a long time and lose the flow

This is software implementing one version of Ted Nelson's idea of visible connection in text. For more on that idea, see ▶ this video which contains beautiful examples.

That's the first thought that came to my mind. I love hearing ted nelson explain it hlink It is a good effort to bring that concept to life. This video is better ▶ this video

Great to see those ideas discussed! It is a little strange, however, that Ted Nelsons ideas around Xanadu and its link representations aren't even mentioned. ▶ this video
