00:23 verisimilitude I've improved my latest article a tad.
00:29 verisimilitude http://logs.nosuchlabs.com/log/asciilifeform/2022-02-14#1079368 I don't really pay attention to the mathematical proof of that or whatever but, unsurprisingly, have also read that when the von Neumann architecture be abandoned, such as by using systolic arrays, all of a sudden it's found that ``lol, that no longer applies''.

00:30 verisimilitude One should always be careful to notice just what axioms a mathematical proof is based upon.
00:30 verisimilitude The ``lying with statistics'' is a special case of ``lying with mathematics''.
00:34 verisimilitude I was referring to `Amdahl's law'', in particular.

17:51 asciilifeform whaack et al : it runs in <1min, compare my output w/ yours.
17:52 asciilifeform ( there is no support for cement yet, this is only a corrected and sped-up variant of my orig. 'makesnap' from '18. )
17:52 * asciilifeform checked 1st, last, and randomly-selected #/hash pairs against various block exploders, matched, fwiw.

18:06 shinohai oh neato!
18:07 asciilifeform shinohai et al: do post once you have chance to try & replicate.
18:07 asciilifeform errybody oughta see exactly same output for given example, bitwise
18:07 asciilifeform would be a++ to check it against whaack's exploder, also.

Nothin' on wiki.installgentoo.com and nothin (that makes sense) on the arch wiki either. Didn't want to clutter up chan and/or make a fool of myself. Looks like I have anyway.

19:09 asciilifeform crtdaydreams: the log exists largely so that folx dun need to repeat themselves when the next fella asks same q
19:11 crtdaydreams I also wanted to clarify, this chan/network seems to be mostly biz for TRB, would I be wrong in assuming it's inappropriate to chitchat and/or go too far offtopic?
19:11 asciilifeform crtdaydreams: nope, not mostly for trb

19:13 crtdaydreams eh wrong message
19:13 crtdaydreams oh lol.
19:13 asciilifeform crtdaydreams: plenty of folx happy to answr noob q's
19:13 asciilifeform incl. re irons
19:18 crtdaydreams okok, well so I'm installing new NVMe, tryin' to figure out filesystem. Ext4 doesn't go <1048 sect. size and calling up nvme id-ns /dev/nvme0n1 displays that it has native sector size 512 and IO 512 aswell. No support for (2^9 somethings instead of 2^12)
19:18 crtdaydreams i.e 512 not 4KiB sector size.
19:21 dpb crtdaydreams, check out http://atruechurch.info/ and don't go to hell like the rest of the world!
19:21 asciilifeform crtdaydreams: seems like your unit emulates classical (512byte) blocksize
19:21 asciilifeform wb dpb
19:21 dpb hi
19:21 crtdaydreams So I've mkfs.xfs -f -s size=512 /dev/nvme0n1p3
19:22 asciilifeform crtdaydreams: e.g. some of the moar recent samsungs actually expose 4096byte blocks. your item evidently not
19:22 crtdaydreams hi dpb, can't go to hell if you can't die! transhumanism101
19:22 asciilifeform crtdaydreams: generally you dun need to explicitly give the block size
19:24 crtdaydreams well the problem seems to be with ext4, I've never used xfs before, there's some stuff additional to disabling continuous trim (a journalling filesystem) that I can't find any easy-to-follow guides on. It might just be a matter of RTFM.
19:25 crtdaydreams I'm playing my cards safe, I did read xfs automatically determines bs but yeah.
19:25 asciilifeform crtdaydreams: fwiw asciilifeform doesn't use trim (it dunwork on iron raid), and also there are known catastrophic bugs in trim support on certain ssds
19:26 * crtdaydreams still doesn't exactly understand what trim does or maybe did but forgot
19:26 asciilifeform subj
19:27 asciilifeform crtdaydreams: notion of trim is to cut down on write wear by reclaiming (on controller side) blocks unused by fs
19:28 asciilifeform (normally controller has nfi re the fs layout, can only supply 'spare' blocks from designated hidden spare list)
19:29 asciilifeform notion is to extend life of the unit. with buggy controllers tho, it is rather like 'extend life of tyres, but auto has 1 in 3 odds of exploding in fireball'
19:30 asciilifeform ssd is cheap enuff
19:30 crtdaydreams ah, a tesla.
19:30 asciilifeform aha
19:31 crtdaydreams well, I can't think of anything else except to just use xfs, or if you'd have a recommendation for a suitable one, that'd be great
19:32 asciilifeform crtdaydreams: reiser
↖ ↖
19:34 crtdaydreams oh shit
19:34 crtdaydreams it handles NVMe alright?
19:38 asciilifeform handles whatever you want, so long as you can boot from it
19:39 crtdaydreams alright. I have to return to the flesh and perform my meat functions.
19:39 asciilifeform laters then
19:39 crtdaydreams Thank you very much for your time, very much appreciated.
19:39 asciilifeform nrp
19:39 asciilifeform np
19:40 crtdaydreams Bit worried about journaling though. If it's anything like xfs than you'd need external journaling to prevent wear.
19:40 crtdaydreams o/
19:40 asciilifeform nope, ordinary journal
19:40 crtdaydreams oh ok, sweet
19:44 asciilifeform the only way to 'prevent wear' btw is to keep the thing unplugged on a shelf. what sane folx do is to monitor wear ( via e.g. smartctl ) and swap the drive when it's time, ~before~ starts to melt down.
