@richlv hmm, there's #shitheads?

@anakita I'm very happy when that happens to me because my first language is russian, the language of the occupants 😢

@amy I may have contributed to it a *little bit* by grumbling about forgetfulness together with mastodon #UX. Could be up to +5 perhaps, but likely +1/+1, based on the amount of interactions I normally have.

Rabbi Boateach is quite #based.

@haskman 🤫

@richlv I think #TechBros does it?

I don't think there is any need to comment.

I'm really sad that I was siding with palestine supporters before Oct 7th. It's almost funny how the people like this Oxford graduate are ready to do everything possible to side-step the holocaust-levels of slaughter showing no respect or regard to the people who have demonstrably supported their cause. Loved the #Belfast tantrum too!

@lonespelunker thank you! I went through many iterations for this, and I hope that I got the most elegant mechanic possible that addresses all the design goals. I would love to see how this works in the wild, in the adventures that don't have the clues pregenerated. Could a referee improv 4 bits of information with one being key about, say, a hex in the black wyrm of brandonsford?

#Israel hitting the logistics in #Rafah is exactly what a country fighting a defensive war *should NOT* do.

Thanks for visibility, @mxhdroom!

It can't and shouldn't be compared to the atrocities of October 7th, but this sort of stuff has a serious #RAF bomber command 1944/45 vibe.

. @ksyu happy to see that you're still on mastodon! 👀

Was really cool to work with you side by side 🙇

@ChrisO_wiki a child's foxhole is a young adult's grave! They'd better get used to it.

tfw you punch in your home domain to do a remote follow and

@ionchy it's interesting. I also can't answer this, especially not in a context of a GADT lecture, however I know what I would avoid doing while attempting to anyway. I would avoid invoking type-value dichotomy! I would probably answer like this, informally:

===

Consider a set of elements. A type then is, informally, a way to split this set into two subsets: one belonging to that type and the other not belonging to that type. As we create the set of these types, it is completely disjoint from the set of elements (it lives in a higher universe), this is why we can use elements from the intial set as we define types.

For example, we can define types that discriminate the elements based on a natural number parameter (natural numbers are normally also elements of the initial set we were considering). These kind of types are called "indexed types" in the literature.

Observe that now that we have this "type zero" universe, we can now consider it as the underlying set of elements and build up "type one" universe by creating types that discriminate the elements of "type zero".

===

I would then tie it back to GADTs like this:

===

In this mental framework then, GADTs over a way to combine several ways to include elements of the underlying into a single type, perhaps recursively.

===

Here I would point at a simple Expr GADT explaining how it allows us to capture all the Nats, all the Bools and, recursively, all the Expr Nats and Expr Bools via Add and And constructors, while at all points creating type Expr a. I would then emphasise that even though Expr a seems to be really open (i.e., one can write Expr String), it really isn't because there is no way to construct `Expr String` with the constructors we wrote down.

But it's certainly a tricky one to come up with on the spot. I wonder how did you respond? :)

#dungeon23 is going strong. Today made pages and pages of content.

May I present you with an #OSE-compatible way to run investigations?
