snsabot: Logged on 2021-01-03 22:16:58 verisimilitude: That is, be there anything much special about that class of programs which, after initialization, have all mutable state live in registers and whatnot?
asciilifeform: verisimilitude: i'll add what the schoolbook ~won't~ tell you : the shared-resource bottleneck is ~not~ the greatest catastrophe of the vn model of computation. rather, it is the shit-sandwich of broken abstractions based on the interrupt.
asciilifeform: interrupts make the very notion of a deterministic process on the machine, a virtual impossibility.
asciilifeform: even pc iron designers conceded this, and offloaded all kinds of processing from cpu to special-purpose micros (in nic, disk, kbd, etc)
verisimilitude: I recall reading an article by Djikstra about how, decades ago, the machine designers weren't implementing interrupts correctly.
verisimilitude: I never thought of interrupts as particular to the von Neumann model, but I suppose this is due to the dearth of other machine types more than anything.
asciilifeform: verisimilitude: entirely particular to vn model. observe again, e.g. fg has no notion of interrupt, because has no notion of instruction flow.

verisimilitude: Provide an example of such a problem; none currently come to my mind.
asciilifeform: verisimilitude: iirc r. feynman's example. he gave a conference table of 'computer scientists' a bundle of sticks, of various lengths, to sort by length. asked about the complexity class of the problem.
asciilifeform: verisimilitude: do you know this story ?
verisimilitude: I don't believe so, but ``spaghetti sort'' comes to mind.
asciilifeform: aha, it.
asciilifeform: sorting is in o(n). unless, of course, yer trapped in a vn machine..
verisimilitude: I'd always thought of that as a consequence of analog vs. digital, not like this.
asciilifeform: ( i'll add to the story -- if yer ~not~ trapped in a vn machine, then sort not even o(n) -- if you can simply tell the sticks to 'walk forward if you see a taller stick in front of you; otherwise stand still' and they take ~at most~ N steps ! )
asciilifeform: verisimilitude: it aint.
asciilifeform: digital does not necessarily imply vn cripplement.
verisimilitude: Well, I suppose this has still educated me a tad; I appreciate it, asciilifeform.
verisimilitude: Some examples of other architectures I've seen is giving the memory minor computation abilities, such as clearing or pattern-embedding; that could be neat.
verisimilitude: I like the idea of being able to tell the memory to set the current memory incremented from the last memory, for N steps, and so having the APL iota in hardware.

verisimilitude: Giving it more thought, that memory calculation idea could be equivalent to embedding a more complex many-more state cellular automata into the memory.
asciilifeform: verisimilitude: there's a great many things one ~could~ do. incl. iron cell-automata. but, sadly, it's a 'you and what army' kind of thing.

verisimilitude: I could see the idea of giving the end address a ``stop'' command, and the beginning address an increment command which propagates to the next memory, until reaching the ``stop'' command. A surprisingly powerful little machine could be built with even, say, eight different commands.
asciilifeform: verisimilitude: familiar w/ 'firing squad problem' ?
verisimilitude: Vaguely, yes.
asciilifeform: there's a whole class of these arrangements.
asciilifeform: just about errything asciilifeform ever discussed on subj, is 1970s state of art.
verisimilitude: The idea of propagating to the next cell in either direction solves the issue of getting the commands there without just doing the calculation anyway.
asciilifeform: verisimilitude: cellular structure solves all kinds of idiocies from conventional comp design, yes.
verisimilitude: I could see bubble sort and varieties thereof being able to be given directly to the memory, but not more complex sorts as easily, although it may not matter.
verisimilitude: I'll make certain to look at that.
asciilifeform: verisimilitude: there's a detailed version, in dead tree (presently not aware of a warez scan)
verisimilitude: I read this lately. So many idiots responded to it with garbage such as ``But C compiler error messages are better now!''; it's pathetic.
asciilifeform: verisimilitude: i stopped reading at :
asciilifeform: 'IntelliJ, Eclipse, ASP, Spring, Rails, Scala, AWS, Clojure, Heroku, V8, Go, Rust, React, Docker, Kubernetes, Wasm. All of these latter technologies are useful incremental improvements on top of the foundational technologies that came before.'
verisimilitude: He makes a decent overall point; it's not a long read.
asciilifeform: well, asciilifeform read.
asciilifeform: not 1 thing in there is new. for fuck's sake, i have an entire site, from '07, re subj.
verisimilitude: I agree.
asciilifeform: and what aint full of plagiarized naggum, is full of nonsense howlers. e.g., 'Today only megacorps like Google/Facebook/Amazon/Microsoft have the money and time horizons to create new technology'
verisimilitude: Yes, that was laughable.
verisimilitude: I underestimated how much of a waste of time reading it was, I suppose.
asciilifeform does not pretend to have any monopoly on 'software died'. but has 0 interest in reading a 'here's a point-by-point plagiarism of asciilifeform's www, but read it because unlike him, i went to harvard and got vc fundings' claptrap.
verisimilitude: Returning to the von Neumann topic, I'd be correct in figuring it's not considered meaningfully different because the improvement is only linear, right?
asciilifeform: wholly unrelatedly : re this irons thread : decided to try this inexpensive display. will report at some pt re whether edible.
snsabot: Logged on 2021-01-03 14:43:31 asciilifeform: unrelatedly: asks readers who (supposing anyone has) bought 3840x2160 ips displays in recent 5yrs, to write in. looking for sumthing larger than current flagship 'nec' 27in. no, not interested in tvisms/non-ips garbage/similar.
asciilifeform: verisimilitude: what different from what ?
verisimilitude: A von Neumann machine with multiple processors, such as a GPU, still only offers linear improvements in general, which is why it's still basically von Neumann is the reasoning, right?
asciilifeform: verisimilitude: not even linear. because they contend for shared resources.
asciilifeform: and impose braindamaged concepts like interrupts and locks.
asciilifeform: (which in turn inevitably lead to irreproducible and subtle bugs in ~errything)
asciilifeform: verisimilitude: and, simply by definition, if you can point to a distinct cpu and to a memory, it's a vn machine. that's what the formalism consists of.
asciilifeform: the relative proportion (e.g. 1 cpu / 1 memory, 2 cpu / 2 memories ('harvard') ; or 9000 cpu / 1 memory (gpu) etc) dun matter.
asciilifeform: *1 cpu / 2 memories ('harvard')
asciilifeform: the most accessible example of non-vm comp is fpga fabric.
verisimilitude: It's still fair to call many von Neumann machines networked something distinct however, don't we agree?
asciilifeform: is called 'many von neumann machines networked together' lol
verisimilitude: Well, shrink each down and that's something like the GA144, which is a dataflow machine.
asciilifeform: sure. except for the fact that abstractions don't actually work, and the constituent pieces actually do matter.
verisimilitude: I'm well familiar with that piece, yes. Each F18A in a GA144 has a true pair of stacks.
asciilifeform: which is why a crowd of hollywood extras with index card of instructions could 'be called a dataflow machine' but you probably wouldn't want to compute on it.
asciilifeform: verisimilitude: i remember the greenarrays machine,yes
verisimilitude: That reminds me of a joke mocking startups.
verisimilitude: ``We switched from MongoDB to thousands of Chinese children forced to memorize numbers.''
asciilifeform: verisimilitude: erry programmer knows 'over 9000' such jokes. but when you point out the one where he himself is protagonist, usually stops laughing.
verisimilitude: Sure, but perhaps the best jokes are written for the one telling them anyway.
verisimilitude: An issue with this memory idea is it doesn't much jive with typechecking in hardware, and some useful operations in memory wouldn't be sensible. A solution, however, is to have memory segmented by the type of data it stores. So, integer memory could have increment operations and whatnot, whereas cell memory could have, say, swap CAR and CDR, although that in particular doesn't seem much useful.
asciilifeform: verisimilitude: i rec to get familiar w/ basics of fpgaism. simply so can see what example looks like of 'fabric' where almost nothing about e.g. memory is apriori forced on the designer (you can pick what length/width of memory to use in a particular 'island')
asciilifeform: and indeed much of the accumulated knowledge re comp design from vonneumann world, is inapplicable in this scenario. in fact is large part of why you can't buy a 'kilogram of fpga' as general-purpose pc.

asciilifeform: any and all attempts to apply any other kind of pill, simply in the end strengthen the idiots.
verisimilitude: I was thinking about crypto addresses earlier. An obvious issue is ``But what about when the crypto is broken?'', but it's important to recognize that the current system is also backed by the same principles, just hidden and already broken.
verisimilitude: So, the current system of ``Just addresses routed honestly.'' is actually a fiction.
