Mutual exclusion: https://en.m.wikipedia.org/wiki/Mutual_exclusion

Are you saying that the Erlang VM enforces mutual exclusion within its Actors, and that mutual exclusion should not be enforced within Actors?


Every Actor has a region of mutual exclusion.

However, the region of mutual exclusion can have holes so that

    * activities can be suspended and later resumed
    * other activities can use the region of mutual
      exclusion while a message is being processed by
      another Actor
For example, a readers/writer scheduler for a database must be processing multiple activities concurrently, which is very difficult to implement in Erlang.

Is this a joke?


Yeah. It’s a slightly modified transcript of a conversation from the movie Training Day.


It's the transcripts they'll recite during the canonization of St. Acton, patron saint of "After I get Mine".


Lol at the flak being hurled at this guy like we wouldn't all do exactly the same thing, were we in his position.


Not true, I would have stuck it out for another year for the extra $850 million.


I mean, that's a lot of zeroes. I was going to say commas but that doesn't really reflect the magnitude right :P


And then used it to build a tech antitrust Super PAC!


I meant the snipes about having sold to Facebook in the first place.



Thanks for this. I read it years ago and was unable to find it since.


Head down the Prof Wildberger rabbit hole if you'd like to explore why we might be able to cast aside chunks of conventional math including real numbers and infinite sets. https://m.youtube.com/channel/UCXl0Zbk8_rvjyLwAR-Xh9pQ https://njwildberger.com


I would be careful taking that stuff too seriously. It's ok as entertainment though.


Might be? Of course we can. Obviously infinite objects are irrelevant to modeling the real world. They are just a shorthand for adding a bunch of annoying qualifiers to every mathematical statement.


> Obviously infinite objects are irrelevant to modeling the real world.

I disagree. The concept of infinite objects are essentially object sets with an unknown limit. This represents a general case from which we can draw important concepts.


It's a good thing we don't actually need the square root of two!

Good use of metaphor.


> metaphor

Simile. Or analogy, perhaps.

... Is that kind of pedantic correction a sign of unlikable intelligence? :P


Not a domain name registrar, but looks useful nonetheless. Looking into this. Thanks.
