03:30 a111 Logged on 2019-06-11 21:38 diana_coman: well, the 18yo me at programming exam-to-get-qualification-diploma got told directly (out of prof's sheer exasperation I suppose): "next time, don't think that much!"
03:31 spyked I'd made a small toy proggy to draw a mandelbrot set, zoom in etc. when the time came to show it, no one in the room even knew what a fractal was, although ~all~ the teachers there were math-informatics graduates

09:11 mircea_popescu in other news, pillars of eternity is a fucking great "good old Infinity engine days". up there with planescape : torment i'd say (not as deliberately-artsy-quirky-???).
09:11 mircea_popescu absolutely must play.
09:17 diana_coman me is basically playing planeshift : torment
09:18 diana_coman can't beat it for that part really :P
09:25 mircea_popescu lmao

12:31 mircea_popescu noo ?!
12:32 mircea_popescu and here i thought that's just what it's for. severe case of who could've predicted!
12:32 asciilifeform orig for write.
12:33 asciilifeform also claims to work on ecc boxen, but asciilifeform not read $item yet and has nfi how substantial is claim
12:33 mircea_popescu nfw ?!
12:34 asciilifeform on the surface, seems to use the ecc corrector delay as sidechan
12:35 * asciilifeform still doesn't grasp why is it that no one sells mobos where can use redundant (majoritated, rather than failover, the latter is dime a dozen) banks of ram.
12:43 mircea_popescu cuz made in china, and chinese man only does what granpa did.
12:46 BingoBoingo Similarly there's a lack of SRAM and boards supporting it.
12:52 diana_coman Unfortunately, as Cojocar et al. [13] show, the synchronous
12:52 diana_coman nature of the ECC correction algorithm typically exposes such
12:52 diana_coman information through a timing channel, where memory accesses
12:52 diana_coman that require error correction are measurably slower than normal
12:52 diana_coman ha
12:52 diana_coman from the paper so apparently yes, on ecc too
12:57 asciilifeform BingoBoingo: i dug into this last yr, it is worse than uninitiated can picture, nobody's even making reasonably-sized sram (deliberately not counting here various 'pseudo-s' etc abominations)
12:58 asciilifeform diana_coman: it makes sense, if it can't correct in O(1) cuz it has to interrupt a burst (all dram since mid-90s runs in long bursts much of the time, typically fill 1 or moar cache lines) then leaks via time.
12:59 asciilifeform even if doesn't interrupt a burst, still leaks 'fact of'
13:01 diana_coman aha
13:01 asciilifeform BingoBoingo: i actually went through coupla hundred datashits in late '17, for various srams. after rejecting various 'pseudo' (i.e. internally dram, with built-in refresher) , left with buncha items, typically <=64MB, where in small print, if you actually use it as random access (i.e. not in long burst) it runs at 1995 speeds (7-15ns typically access)
↖
13:04 asciilifeform there's nothing physically impossible or even especially difficult about making gigantic sram -- you simply need 6 transistors for erry 1 that'd be in the dram yer replacing. simply, no one does.
13:05 asciilifeform cuz britneykonsoomer dun need it for anyffin.
13:05 BingoBoingo Once again mass market makes actual market products impossibru because BrittneyChain
13:07 asciilifeform BingoBoingo: you can still buy all the 1980s-style srams (incl. rad-hard) you like, 128kB 10ns chip is about 4bux. these suffice for the icbms and wherever else folx actually care about bits staying put. what no one makes is sram that'd fit the bloat of 'modern' pc os etc.
13:08 asciilifeform could even say that erry piece of soft gets the irons that it deserves.
13:09 asciilifeform ( why should 8GB of 'drepper-os' or winblowz get 8GB of sram ? it'd be rather a penicillin for a corpse )
13:10 BingoBoingo And yet, plenty of fab for shitcoin ASICs
13:10 asciilifeform cuz they ~pay, lol
13:11 asciilifeform see mircea_popescu's earlier pt re why.
13:11 a111 Logged on 2019-06-06 07:23 mircea_popescu: http://btcbase.org/log/2019-06-05#1917398 << nothing to laugh, it's exactly correct. the long standing slight margin on mining over trading is exactly this, "market participant voluntarily set cost of privacy".
13:13 BingoBoingo Meanwhile in local lulz https://www.montevideo.com.uy/Noticias/Desde-su-implementacion-regulacion-de-Cannabis-arrebato-unos-US-25-millones-al-narco-uc721097 << Nothing of the sort. The folks who used to sling one dope now sling another dope.
13:14 asciilifeform BingoBoingo: from asciilifeform's archaeologies, got hypothesis that market for standalone srams is 99% for repair/reproduction of '80s-'90s designs -- current-day ic which require sram tend to 1) need a few kB, maybe a MB or 2 , and 2) include it on-die
13:15 asciilifeform e.g., last pc that i personally opened that had standalone sram for l2 cache, was a 486 dx2.
13:16 asciilifeform errything after that, rolled it onto die
13:17 asciilifeform ( recall that light in vacuum goes 30m / ns , and charge in solid conductor -- yet slower )
13:18 asciilifeform *30cm
13:18 asciilifeform lol
13:20 asciilifeform btw this figure is in errybody's kindergarten textbook, but is ~extremely~ overoptimistic for electrical machine, where if you have long conductor, it also has capacitance & inductance, if you want to vary voltage on opposite end of it, you have to let it discharge... )
13:22 asciilifeform in asciilifeform's various benchmarkisms (ffalogy etc) found, unsurprisingly, that just about all observed variation in measured performance among current decade of x86 irons, is almost entirely proportional to cache size.
13:24 asciilifeform serious 'non-vonneuman' box would have no standalone rams at all, but simply buncha cpu , each with small mipslike item surrounded by die 99% fulla sram.

16:13 BingoBoingo In US election meddling abroad https://archive.is/1ViEg
16:14 BingoBoingo "En ese punto, la mujer encuestada le preguntó quién realiza la encuesta, a lo que el interlocutor asegura que la Fundación Latinoamericana para la Promoción de la Democracia. A continuación ella le preguntó si la fundación tenía sede en Uruguay, a lo que el encuestador respondió que sí. Pero esa fundación no tiene sitio web, ni forma alguna de contacto disponible. "
16:23 mircea_popescu heh
16:31 BingoBoingo The confirmation though is the "español neutro" which means pointedly not Uruguayan
