10:02 asciilifeform Mocky: neato
10:12 mircea_popescu asciilifeform what could i possibly want with it ?
10:12 lobbesbot mircea_popescu: Sent 14 minutes ago: <asciilifeform> 1-833-867-7282 ( 1-833-TMSRBTC ) ready, if vendor to be believed; ( not tested yet ) . worx in usa strictly, like all 8xx .
10:13 asciilifeform mircea_popescu: it has stats, and, theoretically, shits out wav's when records call
10:13 mircea_popescu send it to bimbo, she can publish them then ?
10:14 mircea_popescu or is this even something tbf wants ?
10:14 asciilifeform lessee what mod6 says
↖
10:15 asciilifeform hrm, apparently the 'record' pheature is a '30 day trial', aol-style, and after that is +7orcbux/mo. i'ma switch it off unless somebody reeally wants it
10:17 asciilifeform i dun really see a massive win from it, tbh
10:18 asciilifeform ( would rather read summary )
10:18 Mocky diana_coman, i've got to find some that speak arabic. so far Indians, Nigerians, Nepalese and Asians all speaking english
10:18 mircea_popescu heh
10:20 Mocky i can see why so few foreigners learn the language, everything is in both english and arabic, signage, food labels, store receipts, even the money
↖
10:20 diana_coman ahaha, so I should have introduced you to some lebanese/kuweitis here, at least they speak arabic!
10:21 asciilifeform Mocky: they escaped from brits , iirc, in '70s. so possibly is why
10:22 mircea_popescu omg a guard booth was empty!
10:22 mircea_popescu britain going to shit! o wait...
10:22 Mocky lol
10:22 mircea_popescu ahahaha check him out, dude's got srs biker gear on and shit.
10:23 mircea_popescu they'd better not fuck with him, these nigerio-nepalese azns. IF they know what's good for 'em.

10:23 mircea_popescu what fucking future ?! for what, england ? jesus x.
10:24 Mocky the side of that thing has the names of other countries on it...
10:24 mircea_popescu aok
10:25 mircea_popescu notably absent, the only countries with any actual future. because who'd have told these tards about 'em.
10:25 mircea_popescu "It was surreal having such a minimal and distant experience of so many places I’ve only heard about before." << ahaha pretty great line.
10:25 Mocky if you look at zoomed in version, nepal, africa, caribbean, so not countries really
10:26 mircea_popescu A350 must be wider than 777 << it is. metric.
10:28 mircea_popescu nice article!
10:28 Mocky thx

11:21 asciilifeform BingoBoingo: i dun recall seeing any multi-anythings in uy ( and i kinda liked it that way )
11:21 BingoBoingo asciilifeform: Well, Uruguay does the thing where they put English words on everything instead of their own language.
11:22 BingoBoingo Hence the Montevideo shopping, the Kiosko CyberInterweb, and the late Pitty Shoes
11:22 asciilifeform aah those
11:22 asciilifeform i think of'em as 'engrish' (asian term, but applicable)
11:23 asciilifeform and hahwat, pitty shoes dead ?!
11:23 asciilifeform what a... pitty
11:23 BingoBoingo Then there's the all English menu at the Burger King, which is a mindfuck because it can't be used without substituting spanish vowels for the English oness
11:23 BingoBoingo Yes, Pitty Shoes is very dead
11:26 BingoBoingo Whole bunch of new shoes in old storefronts along Avenida General Rivera now selling abnormally cheap plasticrap advertising "Calidad Brasilera" too
11:27 asciilifeform BingoBoingo: the only decent shoes asciilifeform owned in entire life... bought in ro
11:27 BingoBoingo But are they suitable for use in Pits?
11:28 asciilifeform BingoBoingo: tested in many a pit.
11:29 * BingoBoingo is very disappointed that there is a botique named Prussia a few doors down from my building that sells women's clothing when it should be selling men's protective headgear
11:30 asciilifeform lol!!
11:30 mircea_popescu lmao
11:31 BingoBoingo The store recently had to get it's glass front replaced after smashing. I assume robbery attempt? Never seen customers in the store though.
11:33 BingoBoingo Then there's all the pop culture kioski names: Kiosko Buffalo Bill, Kiosko Chicago Bulls, Kiosko Tommy...
11:35 asciilifeform miamiism maculae imho
11:37 BingoBoingo Then there's the grow shops of which "Tu Cultivo" is the only one I can recall off hand that doesn't have Grow in the name.

11:55 Mocky with >80% foreigners all speaking english, the Qataris fear becoming ESL. signage is dual language because Arabic is mandated. in 2012 they passed a law mandating universities switch from english to arabic for all degree for all degree programs other than sci/eng/med. in 2016 further law mandating arabic for gov agencies, contracts, schools
11:56 BingoBoingo Fighting the good fight against Miami!
12:02 Mocky unrelatedly, i saw the craziest thing leaving the air port. there are a lot of indian dudes around doing public works type labor jobs. landscaping, pickup up trash, construction etc. I saw one, and i swear he was mowing the grass with a chain saw, all squatted down. now maybe he was cutting something else, but there was nothing else there! and damn if the that lawn wasn't pristine as a golf course

14:53 bvt hello
14:53 bvt decided to add some information to the yesterday's thread on mktemp use in vpatch:
14:53 bvt 1. The vpatch which solved the problem for me: vtools_fixes_mktemp_template.vpatch: http://wotpaste.cascadianhacker.com/pastes/3xcAF/?raw=true
14:53 bvt vtools_fixes_mktemp_template.vpatch.bvt.sig http://wotpaste.cascadianhacker.com/pastes/A5VIC/?raw=true
14:53 bvt 2. Ada internally uses mkstemp(3) to generate a random name when empty string is passed as filename to Open procedure.
14:54 bvt The code in question is in gcc/ada/adaint.c in function __gnat_tmp_name (char *tmp_filename), http://wotpaste.cascadianhacker.com/pastes/cxakJ/?raw=true
14:54 bvt There seems to be no useful code to take from GNAT for this problem.
14:54 bvt 3. Musl calculates a simple hash over current time, address of variable on stack, and address of template to generate the random characters for mk*temp family of functions: http://git.musl-libc.org/cgit/musl/tree/src/temp/__randname.c#n6
14:54 bvt Apparently those addresses are used as 'poor man's RNG'
14:56 phf bvt: i think the conclusion of yesterday's thread was that using mktemp is a bad idea, and that it's better to rewrite temp_file_name to be self contained, i.e. get rid of mktemp pragma and have temp_file_name do its own random string/stat loop
14:56 lobbesbot phf: Sent 1 hour and 48 minutes ago: <asciilifeform> i recently found that lcd panel made by (defunkt) 'pixelqi co', pq3qi-01 , is still sold by chinese ( i have nfi if clones, or old stock ), ~100 $ ea; the thing toggles from 1024x600 colour/backlit into a 3072x600 greyscale reflector thing, worx with various lappies ( sadly not x60, it's a 16:9 )
14:58 bvt I understand this, but still it's better to drop the vpatch, at least in the logs, in case someone else stumbles upon this problem.
14:58 phf i like that ada will create a temp file for you and then clean it up on empty string, though that's a bit too magical (the interface, not the behavior)
15:00 bvt that was a wtf moment for me, i'm not used to such service from the runtime
15:03 phf well, it's also a reason why bug wasn't caught in development. a sequence of wtfs: linux man page says mktemp should be 3 or more X's, so project builds on a non-musl build. meanwhile POSIX mandates there to be exactly 6 X's, so a musl build fails to produce a random string, returning instead a blank one, which is when gnat decides to not only generate a temp file but also do cleanup.
15:06 bvt did you use ave1's gnat or the adacore-provided distro? My understanding is that it should work with both, taking 2 different code paths, and fail only with gnat17.
15:09 phf i've used a variety, including the two you mentioned. ave1's, adacore 2016 and 2018 on linux and mac
15:14 phf bvt: you know you could take a stab at proper temp_file_name :> it'll have to be written anyway, to fix this bug. i suspect by the time someone else runs into this issue, a replacement will already be available.
15:22 bvt i will give it a try. i'm still learning ada, will have to take a look at how strings and interfacing with C are done properly.
15:34 asciilifeform phf, bvt : i thought of a possible algo for sane tmp file creation that dun need rng or global counter. 1) pick a file name in tmp dir, if none exists, take empty string, as string S 2) produce S' = H(S) , H is hash (e.g. keccak) 3) stat(S') ; if already exists, take S'' = H(S') and repeat .
↖
15:34 phf bvt: this doesn't need much C, it's a loop with a termination condition of not Ada.Directories.Exists(Filename), and the tricky part is the construction of said Filename. it could be a Prefix ("vpatch.") + keccak hash(salt + pid + time + ???).
15:36 phf asciilifeform: nah, you want a random seed always, because you're trying to avoid race by producing a least likely collision. the race will always exist between existance check and initial creation
↖
15:36 asciilifeform phf: there's no atomic file create-or-die ?
15:36 bvt right, Ada.Directories.Exists was the missing piece.
15:36 * asciilifeform looked, didn't find, assumed that i simply didn't look hard enuff
15:37 bvt there is a recent linux O_TMPFILE flag to open(2), but i'm not sure we want to use that
15:38 phf asciilifeform: well, temp_file_name makes a temporary _name_, if you're relying on an atomic create, then you need to change the interface, where you try and create a temp file, and then bail. in that case though you don't even need any randomness. just use a counter
15:38 asciilifeform phf: counters won't behave well with '9000' parallel processes.
15:38 bvt and i'm don't know yet if files created this way can be mv'ed to file system
15:39 phf asciilifeform: counters exhibit exactly the same problem as a non-random seed
15:41 asciilifeform phf: also can lock a fixed name in /tmp when incrementing counter or whatever wants to be atomic. tho imho it's ugly
15:42 asciilifeform i suspect however that any solution that works across generic unixdom (i.e. doesn't marry linux) will appear similarly ugly
15:42 bvt perhaps better way would be to create a temporary directory (for which there is atomic create-or-die) at the vpatch start, and place all temporary files there?
15:43 asciilifeform possibly
15:43 asciilifeform if you have a working rng, all you gotta do is take 256 bits from it, and no need to stat() or anyffing; the chance of collision is coupla orders of magnitude smaller than asteroid flattening the machine
15:57 phf bvt: as of right now there's only one temporary file at a time during a vpatch run, so you're essentially in the same situation temp file name or temp directory anme
15:58 phf asciilifeform: i believe that was the real conclusion of yesterday's conversation: you want easy access to a real rng from any republican process at any time, and that makes a lot of idiotic problems go away
15:59 phf but it also seems that before that becomes reality we either have to patch linux kernel or implement a rng daemon or somesuch
↖
16:00 asciilifeform phf: if vpatch in particular cannot be made to work 100% reliably on existing kernels, we'll have bootstrapping boojum.
16:00 asciilifeform really imho oughta be solvable without exotica.
16:01 phf asciilifeform: oh yeah it is, hash a bunch of random stuff, check for collision. that's the pragmatic solution. i'm talking about the take aways
16:02 asciilifeform if you can check for collisions atomically, may as well have ordinary counter .
16:02 asciilifeform ( and it is my understanding that you can, under all known unixen, simply by locking e.g /tmp/tmsr or whatever fixed path )
16:02 phf you're probably right though, the temp_file_name interface needs to be replaced with open_temp_file
16:02 bvt uhm, strace shows me here that the temporary filename changes
16:04 phf bvt: that doesn't contradict what i said
16:04 bvt yes, i misread
16:05 phf tmp file gets created when you have any sort of patching operation, gets cleaned up when you no longer need it. but you could conceivably have it for the duration of the runtime. (except instead of doing file move at the end of a single file patch, you do file copy)
16:07 phf asciilifeform: so the posix solution is to call open with O_CREAT | O_EXCL, which will attempt to create but will signal EEXIST if the file already exists. curiously default behavior O_CREAT will simply clobber
↖
16:10 asciilifeform phf: seems like oughta work ( aside from boxes where /tmp is on nfs drive, but that's a perversity imho )
~ 25 minutes ~
16:35 bvt i will have a look at what primitives i need for the implementation today and tomorrow, and will come back here if i get stuck on something.
16:36 bvt should have implementation done over weekend
