> I do not agree that slice() should operate on extended grapheme clusters. Don’t lump the grapheme cluster/scalar value split in with the sins of UTF-16 and its unreliable code point/code unit split.

Maybe a simpler argument against this idea is that the definition of an extended grapheme cluster changes between versions of Unicode. The relevant standard is on its 47th revision (not all of which change extended grapheme clusters, but many do): https://www.unicode.org/reports/tr29/

In old-school chess AIs, zugzwang is also of interest because it can break null-move pruning[0], which is a way to prune the search tree. "Null move" just means "skip your turn", and the assumption that skipping your turn is always worse than the optimal move. But in zugzwang positions, that assumption is wrong, so you have to avoid doing null-move pruning.

Stockfish's heuristic for "risk of zugzwang" is basically "only kings and pawns left over", alongside logic for "is null-move pruning even useful right now" [1]:

    // Step 9. Null move search with verification search
    if (cutNode && ss->staticEval >= beta - 16 * depth - 53 * improving + 378 && !excludedMove
        && pos.non_pawn_material(us) && ss->ply >= nmpMinPly && !is_loss(beta))
    {

I've almost never needed any of these, but there's all sorts of weird redirections you can do in GNU Bash: https://www.gnu.org/software/bash/manual/bash.html#Redirecti...

It is news to me that manipulating ASCII art is something AI can do well! I remember this being something LLMs were all particularly horrible at. But I just checked and it seems to work at least with Opus 4.5.

claude(1) with Opus 4.5 seems to be able to take the examples in that article, and handle things like "collapse the sidebar" or "show me what it looks like with an open modal" or "swap the order of the second and third rows". I remember not long ago you'd get back UI mojibake if you asked for this.

Goes to show you really can't rest on your laurels for longer than 3 months with these tools.

Eddie Izzard was joking in 1998 about the "The" and the prohibited names for The City (https://youtu.be/QRB_GhLXCds?si=R4kYkodzvYDxe33H&t=276), so it's probably been like this for many decades thence!

I was in the last batch. The average is probably ~28 years old, but there are plenty of founding teams in their 40s and on. Plenty of folks with families. You wouldn't be a dinosaur.

Apply.

Indeed, the RFC says so directly:

   CBOR was inspired by MessagePack.  MessagePack was developed and
   promoted by Sadayuki Furuhashi ("frsyuki").  This reference to
   MessagePack is solely for attribution; CBOR is not intended as a
   version of or replacement for MessagePack, as it has different design
   goals and requirements.

I fail to see what is wrong with having both CBOR and MessagePack, or with trying to bring a MessagePack-like thing to the IETF, if MessagePack's design (lack of extension points, etc.) was problematic for enabling future applications.

Also: CBOR is not one person. The CBOR working group, and the IETF in general, put forward the spec. If you object to how the process went down, your quarrel likely lies with IETF, not any individual.

The crucial argument for me was that I have to trust Facebook forever. Facebook intends to keep your data forever, so you have to trust them for just as long.

I don't think Facebook will go forever without some major data leak. I don't like to count on the competence of corporations in handling secret information.

Similarly, I don't think any human ever looks at Facebook's statistical models for any individual. Facebook likely considers this data of the upmost secrecy. But I'm not sure they'll remain as upstanding decades from now, if they're ever in dire financial straights. In my view, Facebook is only going to get eviler.
