Why HN links it

HN readers link this blog for posts on programming languages and tooling, including Church numerals and the lambda calculus, IDEs that surface the AST, and Linux fsync semantics.

Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?

  1. It would be nice to have an IDE that surfaced something like the AST. Of course lots do to some extent, but I bet there is room for improvement here. This also seems like a place where Lisp would have an advantage since the syntax is so transparent. For readers of yesterday's article about whether all the "easy" stuff has already been accomplished, here is an easy-to-read survey of the state of the art in diffing tr…

  5. > I don't know what the intended use case actually is, Generally speaking, if you've got a database system of some sort and want to write data to a file. > It's still not enough: with write ordering and notification but no instruction to actually write the data soon, the kernel can buffer it indefinitely. That's not really the problem -- being able to say "do this write operation after this other write operation" wo…
