    Does anyone have experience with self-hosted Git? I am currently using Gitea but it updates so fast (including security fixes) that I cannot keep up with it.. I am considering going back to just using cgit (which is annoying to configure). Does anyone have any pointers?

    Here is an ``interesting&amp;#39;&amp;#39; question I have in type theory, and it has to do with Leibniz equality. In type theory, we can formalize a version of Leibniz equality principle on sets as a type ``` Leq(A, a, b) ≡ ∏ (P : A → hProp), P a = P b ``` where `A : hSet`. I.e. two things are equal if no proposition can distinguish them. Thus we &amp;#39;explain&amp;#39; equality in an hSet in terms of hProp-predicates. In case `A : hSet`, the defined Leibniz equality coincides with the us...
