It's really good. He grew up in Bangalore in the eighties. See Two Great Talks on Programming Languages . 23:11 He has said before, in public, that his favourite syntax is raw-parenthetical. See https://pyret.org/ . They call it a scripting language, but it's actually self-hosted. I am not aware of many script languages that facilitate the writing of their own implementation. See  lang/src/arr/compiler/desugar.arr  for an example. 1:22:22 He makes an interesting point about models and soundness proofs. See Moshe Vardi talking about LTLf .  I am still amazed that people accept these undecidability results (where consistency is modelled by soundness in a representation) as if they say something about limits of human reason. See Intensional and Extensional Semantics in Programming Languages and Type Theory. Krishnamurthi has a scribble document instead of a blog: https://parentheticallyspeaking.org/ . They did a good interview with Philip Wadler a few months ago: Compare ...

This is a really great idea. I think she'd do it really well, and there's a lot of related stuff she could investigate. See e.g. A Statistical Model to Explain the Mendel–Fisher Controversy by Ana M. Pires and João A. Branco. Support her on Patreon . Subscribe to Angela Collier .

17:20 The only way humanity will be able to adapt to these ecological shocks is by freeing itself from the dependency on money.  22:45  This economic development is hamstrung by the bullshit of the IMF and the World Bank which are more concerned with maintaining the corrupt status quo than economic and human development.  Subscribe to Glenn Diesen .

The subtitle of this post is "What is a proof and of what is a proof a proof?". Recently Thomas Forster wrote that he had been revising his SEP entry on NF. (There is apparently some excitement about a surprising theorem that it recently proved, something to do with failure of well-ordered choice). See Quine’s New Foundations by Thomas Forster. In the 11 page  1937 American Mathematical Monthly paper where he introduced the theory, Quine opens with: In Whitehead and Russell's Principia Mathematica we have good evidence that all mathematics is translatable into logic. But this calls for the elucidation of three terms: translation, mathematics, and logic. The units of translation are statements; also statement forms, i.e., expressions abstracted from statements by supplanting constants by variables. Thus it is not held that every symbol or combination of symbols of mathematics, say "Δ" or "d/dx," can be equated directly to an expression of logic. Bu...
