it was a really long, stressful road getting here. i'm so incredibly happy to have gotten something lined up, and something that i'm really excited about at that!
@TaliaRinger i've been working on implementing a "pedagogical" proof assistant as a literate haskell program, and having more resources to look at would be really nice
@TaliaRinger are the course materials from your "build your own proof assistant course" publicly available? i saw that nicegeo is up on github, which is super cool! i was curious if you have any notes on unification in particular
i suppose that the point that i'm trying to make is that mathematical thought necessarily transcends any particular medium for its expression, and need not conform to the limitations of any particular medium for it to be valid and worthwhi…
for instance, ink on paper has been the primary tool for the expression of mathematical thought for a very long time, but this tends to impose a kind of linearity to the expression of thought. think of all of the textbooks which begin with…
one thing that's been on my mind is the role of proof assistants. @johncarlosbaez started a great thread a week or so ago about the role of formalisation in mathematics. martin escardo said something in that thread that stuck with me, basi…
working on writing a blog post which i've been calling "structure and interpretation of mathematical theories." i was originally planning to write something fairly narrow, talking about typeclasses and locales, and how they can be used to …
of course, all of this is moot considering that it simply does not appear to be possible to build swift packages on linux
because nixos only packages version 5.8 of swift, i also had to regress the version of `swift-llbuild2` which is used to 1.0.0-beta1.10, the latest version which is compatible with version 5.8 of swift
there also appears to be a documented issue on nixos caused by swift's target string not agreeing with the installed glibc: https://github.com/NixOS/nixpkgs/issues/311565
it also appears that linux is not a supported platform for swift? a swift package declaration takes a list of supported platforms, all of which must be of type `SupportedPlatform`. there does seem to be a `Platform` defined for linux, but …
