A tale of four theorem provers - https://blueberrywren.dev/blog/primes/
> Broadly speaking, both Lean and Agda are dependent-types based systems, utilizing the Curry-Howard correspondence to prove theorems via a complex type system, whereas Isabelle/HOL and HOL4 are LCF-style systems, with a small "proof kernel" containing base rules (e.g. forall x, x = x) that all proofs must be constructed via.
In all my years of reading - and I've written my fair share of dangling prepositions - this is the first time seeing "via" at the end of a sentence. Let me guess the author is German, Danish, or a mathematician.
These abbreviations were not defined before use.
- LCF: Logic for Computable Functions - https://en.wikipedia.org/wiki/Logic_for_Computable_Functions
- HOL: Higher Order Logic - https://en.wikipedia.org/wiki/HOL_(proof_assistant)
Another thing that irks me is they've started using "I", "me", and "my" - an attempt to prey on the psychological projection of its users, to create a fake emotional connection with a thinking subject.
It's not about you, and you would know that if you've been paying attention to the progress of history and human rights in the past century.
Sounds so juvenile, worse than a teenager. Unfit for running a company dealing with secure mail.
