unpx: do you have a link to the algo ?

12:31

*

asciilifeform looked at a # of 'lubyisms', found that the moar theoretically-optimal sorts tend to be 1) painfully complicated to implement 2) very high constant cost, such that they aint likely to win in re pest, where most common use case is likely to be simply one station sending to anuther, wanting to eliminate effects of pa

12:31

cket reordering -- rather than e.g. torrents where yer leeching warez from over9000

asciilifeform was looking concretely for such algo where one could determine, in o(1), whether ~any~ given chunk is corrupted/spurious. but afaik no such algo is known

~ 1 hours ~

13:35

Yet another translated paper from russian hehe

13:40

Trying to look up for a survey explaining everything

13:46

Also, may I have a look at those that are painfully complicated to implement?

13:53

unpx: 'turbo code' iirc

13:53

they're all somewhat gnarly imho

13:53

unpx: do you have a link to the mentioned ru paper ?

13:53

>Turbo codes compete with low-density parity-check (LDPC) codes <<< oh lol I'm gonna study these

https://unpx.net/uni/codes/rank_code1985Engl.pdf << and the translation for non-ru

13:54

non-ru readers, actually, otherwise it seems an offense

13:55

lol re the 1980s fax machine quality of ^

13:55

unpx: you were able to read that?!

13:57

subj loox (at 1st glance) like a refinement of ye olde reed-solomon ( think usenet's 'par' format )

13:57

I didn't read it, I just found the reference, I cannot share the slides (yet I hope)

13:58

It is indeed error-correction focused rather then lossy channel countermeasure

asciilifeform still not had time, sadly, to try signpost's demo stream coder

14:01

( see e.g. )

Logged on 2023-02-03 11:33:47 signpost: were I to generate the aux blocks on the fly, next decision would be whether to lazily advance the prng which produces the message-aux edges, or precompute that.

14:07

Rank-metric codes are used for code-based crypto (aka PQCrypto) and linear network coding, but I cannot find a reduction from linear network coding to online codes...

14:13

I think for example that, in the vector case, if you receive only a few bits (hoping they are tagged, so you know which one are missing) one may fill the missing bits with random data and recover the message with error-correction.

~ 15 minutes ~

14:29

Will read better and come up to a conclusion

~ 3 hours 29 minutes ~

17:58

today i had a breakfast prepper breakfast, local beans from last year, eggs from friend's farm, deer steaks from last year's hunt, home made bread and amish butter. this collapse thing is breddy good.

􏿽asciilifeform, had this in backlog, https://www.youtube.com/watch?v=G56lE2407Ls and https://www.youtube.com/watch?v=Sw7BzjSmuqg the videos are kind of tedious, but if you play them in background, you can get insight into state of elbrus, and the current happenings as far as custom

􏿽cpus in ru. second video with an elbrus gov integration director is particularly telling, mostly by the dynamic between the old school "kids and their videogames, why don't you start a science кружок for young pioneers" director on one side and the "modern" elbrus enjoyer on

􏿽 the other

http://logs.bitdash.io/pest/2023-03-21#1025019 << little known fact, outside of ru intelligentsia, that books were one of the best investment vehicles. were generally hard to obtain, held their value, could be bartered for шуба etc.

Logged on 2023-03-21 12:13:30 asciilifeform[4]: 'savers' generally hoarded paper cash (all retail economy, Official or otherwise, was cash-only)

18:42

a sparwling bookshelf was a sign of wealth, because was literal bank, many hoarders never read any of them either

~ 1 hours 45 minutes ~

asciilifeform watched father barter/hoard b00kz (even actually read'em, lol), inherited the worst aspects of the habit

20:29

he never afaik sold any, except at the end, was 1 of what paid for the plane tickets

20:30

http://logs.bitdash.io/pest/2023-03-22#1025069 << wonder whether it's about the 'real' elbrus or the sparc-elbrus. ('dead end' describes imho both, lol). will need to actually watch the tape to find out, i suppose

asciilifeform mostly forgot about the subj after barfing re ~100%-undoc'd (safe to presume -- to conceal that ~99% of the supporting silicon was licensed from taiwan, and 100% -- baked there) retail elbrus

20:39

*

asciilifeform recalls naively thinking along lines 'hm, maybe they'll bake not only cpu but proper os and prove that you dun need nanometre scale, micrometre moar than suffices if yer programmers not morons' etc

20:41

asciilifeform arguably was 'behind the times' re technopolitical landscape of current-day ru. where no one, evidently, who even vaguely wants such a thing, lives, or has for decades.
