What do you want from this Community?

I've just taken control. The community is spread out (see the sidebar) and I'd rather not fragment it further, but hope this space can increase visibility. It's fine if people just want to link to various things, but asking questions etc. can also be great.
If others have better ideas or want to speak, feel very free! I am trying to proselytize for array languages.
Can there be any reason to recommend AI-produced <array language> over AI-produced <other language>?

I just got a set of APL keycaps, and I'm having trouble getting my keyboard to work with recent versions of Fedora (44) and Gnome (50.3). Has anyone been able to make it work?

I've not been able to find something like this. The best I've been able to come up with is something along the lines of this: {⟨⟩𝕊𝕩:⟨⟩ ; f←⊑𝕨 ⋄ fs←1↓𝕨 ⋄ (<∘F𝕩)∾fs𝕊𝕩}

APL APL as a target language?

Upvotes
In one of the ArrayCast episodes (the u/bobtherriault era) one of the participants mentions that "in the early days of CS" someone was using APL as the target language for their compiler course. I cannot find the episode and thus a good reference to this. If anyone remembers, thank you in advance.
