dulapbot: Logged on 2021-12-05 16:28:18 asciilifeform: cgra: by design, the only block a trb node can ever meaningfully process, is the 'next' one, whatever it happens to be.
cgra: setInventoryKnown]["spam guard"]
asciilifeform: cgra: hm. plox to detail proposed algo, then. (and how it'll behave when talking to an unmodified trb-compat. noad)
asciilifeform: afaik currently all (incl. prb) noades throw their 'latest' block at all peers; so yer stuck processing (often enuff, if node not fully synced -- expensively rejecting) it
cgra: asciilifeform: i'll just make a blog piece of this too, sometime soon(ish)

adlai: it's unfixable by now, although the previous day's log page contains a broken link due to IRC message fragmentation (specifically, the link to cgra.net for the text "spam guard")
adlai: I'm uncertain whether there is any reasonable action item from that specific failure; that exact pattern is detectable by the log server, and all that remains is convincing myself that such automated detection-and-fixing is not unreasonable.
adlai: verisimilitude: the conversation didn't cease, it was "only resting"... I was even still connected to dulapnet, only parted from the channel.
adlai: wrt birthdays: for some reason, the magic number that I recall is 23, not ~30... sure, these are same OOM in base decimal, give or take a hand, although I wonder whether my mind plays tricks again.
adlai: the heuristic which I recall is that you can expect a 'Birthday Collision' somewhere around (sqrt (length sample-space)) samples; for the solar year, this is slightly over 19.
adlai: in other yakshaves, I wonder what convention to adopt for parenthetical remarks, given that I prefer to reserve #\( and #\) for lisp code, and it could be seen as excessive overloading to use them for both code snippets, and parenthetical remarks; easiest unknotting is simply, "do not make parenthetical remarks; either speak, or don't."!
verisimilitude: I referred to the email conversations, adlai.

dulapbot: Logged on 2021-05-19 14:24:35 snsabot: Logged on 2020-07-18 19:55:54 asciilifeform: trinque: since you mentioned script langs: considering, after ffa, to attempt a 'dethompsonizing' simple gc-less scheme in asm, in style of 'M' as a scripting lang. can't speak for erryone, but i've wanted a <32kB scripting lang that 'compiles with bare hands' for many yrs.
verisimilitude: I've become increasingly convinced over the past few months that programming is best done with as little computation as feasible.
verisimilitude: Computation is disgusting where unnecessary.
verisimilitude: I refer to tables.
verisimilitude: As a very basic example: Consider comparing an integer to a static limit, without using a comparator.
verisimilitude: Consider an octet; the problem could easily be solved by a bit-table for each value.
verisimilitude: However, suppose the limit is high.
verisimilitude: Suppose it be noticed the first four bits must be one for the limit to be plausibly hit.
verisimilitude: Well, that enables a sixteen-entry table conditionally used with a few ANDs.
verisimilitude: That's arguably nicer.
verisimilitude: It uses the square root of the space of the former table solution.
verisimilitude: I want to program with tables and simple composition rules everywhere.
verisimilitude: Tables give the ability to easily review and dynamically modify a running system, as well.
verisimilitude: Why have opaque functions over tables, where unnecessary?
