Hal Abelson on Language Embeddings

Subscribe to El Evans.

Here's the full lecture: the first part covers basic lisp stuff, the second is a prelude to the above lecture and the third part continues with this method of describing pictures using computations on linguistic structures. After watching that you might wonder "Well how the hell did we end up with TeX and LaTeX?!"

I remember having fun embedding little languages into the SML top-level. Godel's System-T was only a dozen or so lines of code. That said, I am not exactly sure what sort of embedding I was doing! There are some examples in this Standard ML functional implementation of Hindley-Milner Type Inference: https://prooftoys.org/ian-grant/hm/. See Hilary Putnam on Philosophy And our Mental Life.

See Ian Grant's Weather Report julio 22, 2022 for some more ideas about language Embeddings. There is also this message from July 13, 2000 Infix arithmetic module describing a way of embedding parsers into scheme. What is deep embedding and what is shallow embedding?

And on trying to get to the top of the language hill: see Genesis which was where I was at in 2013. See also from 16:42 in yesterday's weather report: Ian Grant's Weather Report

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did
