Matt Godbolt and Ben Rady Talking About Data Compression


Matt and Ben talk about how compression works, specifically deflate, which is apparently everywhere. Ben gets particular about compression ratios. Matt explains how to compress /dev/random by sorting it first. See the transcript here: https://www.twoscomplement.org/podcast/compression.txt

At 37:20 Matt talks about domain-specific transforms, and at 40:40 he mentions some kind of supercombinator type compression scheme. See Total Functional Programming. Sadly David Turner died last 19th October. He really knew how to program!

Here is an idea about formalising the notion of top-down context that might be interesting. I wrote it in 2009, just after I moved to Bolivia. It is only one and a half pages long: On Tarski's Semantic Notion of Truth.

And it's funny, the other day I was thinking about the  Universidad Mayor de San Andrés, as you do when you think about earthquakes, ... oops! http://www.informatica.edu.bo/ and I just learned that the University of St Andrews is older than the one at Cambridge. A taught one-year Computer Science MSc course at St. Andrews will cost around £18,000 (BOB 180,000) for self-catering accommodation and teaching fees, for UK students. Foreign students will need around.£35,000 (BOB 350,000) for the year, plus travel and living expenses.

... 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, ... Sounds like Edith (II) Rix has been online all the t...

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 ...
