Framedragger: #trilema is
mircea_popescu's constant disappointment, then
ben_vulpes: kinda surprised to not see a gf lending metaphor from
mircea_popescu diana_coman: ahahaha
mircea_popescu; it sounds... familiar already
Framedragger:
mircea_popescu: you sure you want benchmarks? /me thinks it's a lost cause
Framedragger:
mircea_popescu: which means that i don't see how it could work even given mystery-amazing fs performance (...), *space-wise*.
Framedragger:
mircea_popescu: so in your proposed-to-be-tested scheme, there are two separate eight-deep trees? may i ask, why do blocks need their own tree - after all, it's just an int. do you expect block number to overflow an unsigned 32 bit int? because you *really* don't need 8-deep structure for dispersing 2**32 nodes (again:

mircea_popescu: Framedragger the most pressing matter to my eyes right now is getting ext2/ext4 benchmarked for our specified purpose.

mircea_popescu: contrary to what ANYONE may pretend, ext4 IS NOT A FS!!!! it's a ridiculous toy at best.
Framedragger:
mircea_popescu: to be clear, the way this would work is, there'd still be symlinks at the bottom ends of the dir structure, pointing to blocks (which are stored in a single dir, say)?

mircea_popescu: i can't bring myself to move my piss away from dks, or anyone in his generation's face.
Framedragger: asciilifeform:
mircea_popescu: for completeness, i should state that it may be "workable" (in the sense of slightly less horrible) to just keep a flat dir tree structure, one or two levels deep - if you don't ask fs to list files in dir and just want to access filenames you already know, it's ~okay-ish. but i think i agree that the whole fs idea needs to be dumped, in general

mircea_popescu: dude, they fucking gutted them. olympus agreed to pay the usg ~70 billion yen in fines, and install obama's children as an "independent outside monitor". whole corp market cap being you know, 1.3trn or some shit. who the fuck pays 5% of the market cap as a fine already, what is this, Совет Экономической Взаимопомощи ?

mircea_popescu: i noticed that here focusing on something is an incentive for others to also focus on it

mircea_popescu: i did describe earlier, having concluded a few yrs ago that it is cheaper, easier, moar pleasant, to cut appart 'snap4' emulator (i have a pc build here ~with debug symbols~, comes apart in ida nicely) than to suffer with nitric acid and electron microscope

mircea_popescu: aha, i started at one point to do it, and realized 'wtf why'

mircea_popescu: the guys did actually splendid work, read the paper, worth it.

mircea_popescu: im not against the idea in the slightest. i'm just very unpersuaded by the theory hard drives work, to any spec, in any sanemanner.

mircea_popescu: the noion that hdd is usable or useful is a cute pipe-dream of the web generation, unsupported in cold reality.
a111: Logged on 2017-03-10 18:24 asciilifeform: Framedragger: there was old thread with
mircea_popescu , where he stated that usg and china attempted it at same time, and perma-deadlocked
a111: Logged on 2017-03-10 18:12 asciilifeform: ( i can already picture
mircea_popescu spitting out his breakfast, 'modern hdd dun have cylinder, you nut' -- except, it in effect DOES, fetches massive blox , whether mechanical or ssd, by design, for ages now )
mod6: <+
mircea_popescu> how goes mod6 << eh, it goes. getting ready to release V 99994 here soon. mom was diagnosed with stage 4 small cell cancer about 6 weeks ago -- so that's been pretty intense.
Framedragger:
mircea_popescu: (i thought with "sounds great on paper" you were responding to possible kernel module workarounds. but if you're against the *whole* idea, fair enough.)
Framedragger:
mircea_popescu: but if you read further down, we were saying that it may be possible to just access a raw block device without kernel module :)
mod6: ah nice
mircea_popescu!

mircea_popescu: Framedragger i don't get it, you graphed some functions ? or ?

mircea_popescu: so all is not lost! stupor abounds and thanks to the ever advancing technologee is now cheaper than ever!

mircea_popescu: phf the story of alpha is perhaps one of the best illustrations of the fundamentally anti-intellectual stance and calling of the female state. 1980s true 64 bit architecture, well supported (openvms started there, ffs, go revolutionize shit in 2015 with the remnants of 1980s tech). "sold" to fiorina's company, never heard from again, because gotta prop up intel.
BingoBoingo: <
mircea_popescu> (he means republic of china, yes, not the communist fake state ?) << Well they both lost

mircea_popescu: i know a handful
Framedragger:
mircea_popescu: basically, and that's strictly it - because i couldn't intuitively wrap my head around the fact that average number of nodes per specific folder would be _really_ low if depth is say more than 3. still weird in my head, but yeah.

mircea_popescu: nothing generally forces you to keep a block other than a collection of transaction-files, for instance. the exact implementation is up in the air for exactly such reason\

mircea_popescu: meanwhile i ended up with a python dependency via blender ;/ i dun think it's going anywhere.

mircea_popescu: this way you don't actually have to ~index~ anything, if you wish to see where txn 1234567890 was included in a block, you go to /12/34/56/7890 which points to block x

mircea_popescu: the other problem is that a good db fix is a very large project, because bitcoin is written insanely. and our fs db isn't moving, last i heard a month ago someone was going to try and profile an extx

mircea_popescu: well, on the battlefield you're the events are unfolding in real time and timing is important. in lyceum you can do things at leisure. in the later case you decide how long you have for the lesson, in the first case the enemy does
Framedragger:
http://btcbase.org/log/2017-03-09#1623585 << i humbly think there is a bit of a false dichotomy happening here (first approximation of what "here" is could be, "
mircea_popescu's head.") either X is doing useful work for tmsr, or X is necessarily wasting time doing whatever-X-but-not-tmsr'y things (including "having dayjob(s)", "large side-project", etc.)
