Logged on 2022-01-29 16:06:04 whaack: asciilifeform: the genesis starts with a decently high difficulty, it would take a while to generate the synthetic blocks on a home computer

~ 2 hours 1 minutes ~

02:21

anyone got the ATC chain?

02:28

wasn't that just a new genesis with v4ish?

02:34

I forget, but I seriously doubt tat cooked it for a week

02:39

possible readymade reorg initial testchain, replete with wayoff timestamps

02:43

may not exist in any zoo

02:47

asciilifeform dun have it

02:49

arguably a waste of kwhrs in anycase

02:51

although, potential for previously unknown weird exists

~ 2 hours 28 minutes ~

billymg: eggog 500 on pestlogger www ?

05:20

just noticed, looking now

05:21

looks like postgres crashed. trying to start / restart / stop it gives: pg_ctl: PID file "/var/lib/postgresql/10/data/postmaster.pid" does not exist

05:24

billymg: iirc that's the lockfile. start oughta work

05:24

start gives: * WARNING: postgresql-10 has already been started

05:25

kill it manually (if alive), rm the lockfile, oughta start

05:25

but no postgres processes turn up

05:25

`ps aux | grep postgres` no results

05:25

do you know off hand where the lockfile is?

05:25

dmesg dun show any disk eggogs, does it ?

05:26

the pid thing ~is~ the lockfile iirc

05:27

( check /var/run/postgresql/ also for pg liquishit )

05:27

*

asciilifeform not witnessed this particular barf afaik

05:29

dmesg shows some out of memory errors actually

05:29

Out of memory: Kill process 16688 (postgres) score 186 or sacrifice child

05:29

nuffin suggestive of ssd demise, neh ?

05:30

Killed process 16688 (postgres) total-vm:685136kB, anon-rss:1612kB, file-rss:367580kB

05:31

*

asciilifeform must, unfortunately, to bed

05:31

asciilifeform: can't say i'd know what to look for re: disk problems

05:32

billymg: eggogs featuring /dev/sda, sdb

05:32

nah, none of those

05:32

aite then soft barf

05:33

*

asciilifeform will bbl, will help investigate tomorrow if billymg not finds pill earlier

05:39

gonna restart the box

05:43

well, restart didn't appear to help

05:44

ah, wait, now it's back

05:53

so looking at the postgres logs it looked like it indeed kept getting kill-9'd by the os

05:55

prior to that it was getting some bogus queries through the crawler www, e.g. lookup info where host=drupal.php

05:56

so possibly the site got it by a bot that was trying to sql inject

05:57

none of the queries had any bad effect, other than wasting pg resources (my fault for not having sanitization in place at the app level)

06:09

i backfilled the lines in #a from asciilifeform's logger. only one line was dropped in pest (which i pasted in the channel). i've added 8gb of swap to the rk for now but will have to plug the unsanitized client input hole tomorrow

11:05

sometime earlier, i made two experiments to verify some upper limits of blocks. at the time they weren't valid blocks, but i rectified that in the mean time: it took perhaps <1 hour per block to mine, with an 8-core CPU, and a python(!) miner

11:05

(therealbitcoin) 2020-10-03 cgra: asciilifeform: re your ada piece, i hand-crafted two versions of #1 block (although with invalid hash and merkle tree, had to temporarily disable those specific checks to experiment).

11:05

asciilifeform: btw, did you ever comment on this one? valid block species now here and here (obv the eating node must've chain height below the builtin checkpoints)

11:05

(therealbitcoin) 2020-10-03 cgra: one of them had ~1MB output script, the other had ~112k outputs, and they both got accepted by trb (fresh install, 0% synced). i saw much tighter limits set in your code

~ 5 hours 7 minutes ~

16:13

cgra: oh hm, must've missed somehow?

16:13

cgra: how the hell does one stuff ~112k outputs in <= 1e6 bytes tho

asciilifeform rereads nqb structs, can nao see how

asciilifeform when gets a chance to pick ^ up again, will have to properly calculate the maxima...

18:04

for example, the last dig i did was "what's the last block mined with the hard-coded, minimum difficulty the genesis block started off with?"

~ 21 minutes ~

18:25

cgra: yep, imho this can be generalized to perhaps an async RPC mechanism.

18:26

would be quite marvelous to interact with "bots" in this manner, where you pass them a structured request, and receive a structured response back via pest.

18:26

the IRC request -> paste response mechanism is a rough approximation that can be much improved.

thimbronion

speaking of old threads - bitcoin-assets appears to be gone.

18:39

thimbronion: gone from where ?

18:40

but upstack, the logical progression of IRC botworks is being able to (deedbot:deed "signed payload to be deeded") into pest, and receive back an ack that it was heard.

18:41

obviously s-exp is perhaps not the best encoding, just giving it as a placeholder.

20:18

or hm, iirc needed 32 leading 0 bits at diff1. which'd make the genesis, with 43 leading 0's, 2^11 i.e. '2048x harder than had to'

Logged on 2020-05-15 21:00:56 asciilifeform: lru: w/ bitcoin proper, as late as 2013 there were trojan payloads that (with variable success -- variations in iron/drivers made this nontrivial) gpu mined.

trb noad operation was sometimes quite erroneously given as example of 'useful' payload for hypothetical bots; but if you think about it, it takes considerable sweat even for ~willing~ operator to maintain a noad worth connecting to
