Also Cross-Referencing Editor Facility Kent wrote at Open University in England one summer on the Zmacs/Zwei #emacs substrate.

Live chat in #lambdaMOO as always, and I will also be watching #emacsconf on #irc. Please do engage with Kent directly live (through my voice)

Is Google search getting worse? Maybe what we want from it has changed
By Ellen Phiddian

Has the simple search become less useful in a world of low-information, SEO-optimised sites, and often faulty AI summaries? Are there better ways to navigate the web?

See the page - Interviewing @kentpitman Live in less than 23 hours about his writing of the CREF editor tagging/hyperlinking/answer-generating (kind of) in the 80s. Links to Kent's thread on the page.

The SDF Mastodon is down can cannot be expected to recover before the show. PLEASE boost this one for visibility, and Kent's thread (and add questions/comments to address there).

People say it's a misconception that quantum computers can evaluate a function on all its possible inputs in parallel. But actually a lot of quantum algorithms do begin by applying a function to a superposition of all possible inputs. It's just that after that point you need to do some difficult linear algebra and you can't always extract the information you want.

In fact, you can define a lot of important complexity classes in this way. The set of problems solvable in polynomial time with an oracle that evaluates a given circuit on all its possible inputs and tells you …

P: … nothing.
BPP: … a randomly chosen output.
PP: … a majority output.
NP: … if any of the outputs is nonzero.
co-NP: … if all of the outputs are nonzero.
PSPACE: … a fixed point.
