The Syndicated Actor Model started off (see dissertation) without any notion of object or actor or entity reference at all. Actors inhabited a single dataspace and there was no baked-in addressing. Since then various developments have led

Absolutely. A message queue with pattern-based retrieval is a hacky way of getting the first two-thirds of a tuplespace. But, like using a database as a message queue, while it kinda sorta works for the most part, the benefits of the model

Yay! I'm currently working on this (slowly, among many other things). Come visit #syndicate on libera.chat, if you would like to chat about this stuff!

Feels similar to the dbus serialisation format.

32 mpg isn't great compared to e.g. a boring Toyota hybrid.

Operationally, you don't have to do the wrapping: since (a) is equivalent to ^a, you can substitute the implementation of the latter when you see the former. Though if `(a)` is observably "no longer a value" of course then

The page says that "`(foo bar) force` is the same computation as `foo bar`" and that "`^a force` is the same computation as `a`". So then `(a) force` should be the same computation as `^a force`.

Could ^a be dispensed with? It looks like (a) is equivalent to it.

It's a typo for CBPV, Call-By-Push-Value.

There's rather a lot of new syntax, and, more importantly, exploration and experimentation with new syntax involved. Python syntax is... not easy to extend. Let alone on an experimental basis.

This depends heavily on the project you have in mind. How long is a piece of string?

It wouldn't necessarily be slow! There's this wonderful paper from Usenix OSDI 2014 [1] in which the authors present an eidetic system : "a computer system [should] provide the ability to recall any past state that existed o

The answer turns out to be “no”, by the way, but for a while there I was truly confused! Score yet another for Betteridge, it seems.

Strange protocol. Why not pass a path to a file that should be `touch`d and/or written to, I wonder? Would avoid the complexity of sockets.

Delightfully, RFC 9485 https://datatracker.ietf.org/doc/rfc9485/ "I-Regexp: An Interoperable Regular Expression Format" was published just back in October last year!

Kernel-style fexprs give macros plus a bunch of reflective abilities that even macros don't provide. Lazy evaluation (alone) doesn't do that.

Depends how far back you go. Human ancestors were nearly all fish, for example.

Underlined rather emphatically in The Diamond Age by the literal murder of the clichéd cyberpunk character right out of the gates. Quite an unambiguous statement about What Will Not Be Happening In This Book From Now On.

Thanks! And good idea. The ideal time would have been early 2023, because things have drifted into bitrot a little already. I'll tidy up and see about showing it off hopefully in the next few days.

You might enjoy http://synit.org/ , perhaps. Heavily inspired by both Smalltalk and Erlang. (It's my own wee quixotic project btw)

It can already kind-of do a REPL, so it'd be about making sure access to that functionality was robust, and then it's a matter of removing packages from the system until it's as small as you'd like. Assuming a subtractiv

No, not necessarily. Various Smalltalks have a wide range of different approaches to UI and IO more generally. This (their "operating system aspect" https://eighty-twenty.org/2019/01/13/why-learn-sma

The problem is you can't statically know, in e.g. Dan's `generate-data`, which to call: close() or shutdown(). You have to reflect on stdout to discover what kind of resource you have. So there's a downside to the inconsisten

PASV works around some but not all NAT breakage. There are things FTP can do outside a NAT that it can't do with a NAT around. (Workarounds can be concocted, but NAT really did take away some of the natural abilities of FTP.)

The complexity I have in mind is roughly that the TCP state machine isn't quite the cartesian product of two opposed unidirectional state machines, but it could be. (No proof of this, only a TCP implementation based on the idea. I
