16:47 πŸ”— xmc dang
16:50 πŸ”— chazchaz That's really nasty, and means something is really screwed up because it shouldn't even be remotely possible.
16:53 πŸ”— xmc w10 seems to be getting good at Things That Shouldn't Happen
16:57 πŸ”— anomie Case in point: http://www.sounddevices.com/news/sound-devices-news/sound-devices-technical-alert
16:57 πŸ”— anomie "We have confirmed user reports of a serious issue with Windows 10 and removable media formatted as FAT32. Users are experiencing corruption of .wav media files by simply inserting FAT32 formatted SD or CF cards into a Windows 10 computer. Files do not need to be opened or accessed in order for them to become corrupt."
16:58 πŸ”— xmc yes that was posted just an hour ago
16:58 πŸ”— xmc it's what we're talking about
16:58 πŸ”— anomie Oh.
16:59 πŸ”— anomie Didn't realize it was that popular.
16:59 πŸ”— anomie Unfortunately, fat32 is still how you need to format stuff if you need to work on virtually everything.
17:01 πŸ”— xmc yep
17:03 πŸ”— anomie It'd be nice if we could have a /decent/ filesystem that works on the big 3 (Windows, Mac, Linux), but I guess Silicon Valley can't even accomplish that much.
17:10 πŸ”— robink has joined #archiveteam-bs
17:12 πŸ”— dashcloud anomie: udf probably would work, but as it's almost always used on DVDs, it'd be hard to say how it would work on a non-DVD medium
17:22 πŸ”— xmc whatever you choose will never work on the windows xp machine at the kinko's where you need to print a thing quickly
17:32 πŸ”— arkiver2 has joined #archiveteam-bs
17:34 πŸ”— anomie Then move it to a fat32 drive for that?

17:52 πŸ”— aaaaaaaaa has joined #archiveteam-bs
17:52 πŸ”— swebb sets mode: +o aaaaaaaaa
17:57 πŸ”— aaaaaaaaa I wonder if exFAT has the same flaw, but I don't even know what would cause something that bad
18:09 πŸ”— anomie exFAT?
18:09 πŸ”— anomie Like, there most be more people that use ext4 than exfat.
18:10 πŸ”— primus104 has quit IRC (Leaving.)
18:11 πŸ”— anomie Is it possible to send a TB hard drive to the internet archive (for faster bandwidth) and then have it returned to me?
18:11 πŸ”— anomie Or do they need to keep it?
18:11 πŸ”— aaaaaaaaa has quit IRC (Read error: Connection reset by peer)
18:12 πŸ”— aaaaaaaaa has joined #archiveteam-bs
18:12 πŸ”— swebb sets mode: +o aaaaaaaaa
18:19 πŸ”— anomie So, is a kilobyte 1000 bytes, or 1024 bytes?
18:20 πŸ”— aaaaaaaaa depends on who you ask
18:20 πŸ”— aaaaaaaaa and the problem domain too, I suppose
18:21 πŸ”— anomie >depends on who you ask
18:21 πŸ”— anomie Really?
18:22 πŸ”— anomie What are standards organizations for then?
18:22 πŸ”— aaaaaaaaa making money
18:22 πŸ”— aaaaaaaaa at least for the people involved
18:23 πŸ”— anomie Fair point.
18:23 πŸ”— anomie But I really think this ambiguity is one of the tech industries biggest fuckups.
18:24 πŸ”— anomie At least, unlike metric/imperial, it's not likely to cost so much money.
18:24 πŸ”— SimpBrain has joined #archiveteam-bs
18:25 πŸ”— aaaaaaaaa well, I think it is two problems, 1 is the fact that the k/G/T etc. was already used for base 10 exponents and 2 hard disk manufacturers found an easy way to save 2.4% or more off the top
18:26 πŸ”— anomie The second is?
18:27 πŸ”— aaaaaaaaa hard disk manufacturers switching to 1000 instead of 1024
18:29 πŸ”— anomie But aren't they just following the IEC's standards? How is that a problem?
18:32 πŸ”— aaaaaaaaa because for a long time kilobyte meant 2e10 in base 2 and it introduced ambiguity.
18:33 πŸ”— anomie Then why call it a kilobyte?
18:34 πŸ”— aaaaaaaaa like with memory vs hard disks capacities, or why Windows says the capacity of my disk is less then the sticker, etc.
18:34 πŸ”— aaaaaaaaa why call it a byte? We give things names and they mean whatever the namer wants
18:34 πŸ”— aaaaaaaaa at least until usage takes over, I suppose.
18:35 πŸ”— anomie But then why use terms from SI?
18:36 πŸ”— anomie Though honestly, I don't care too much whether KB means 1024, or 1000.
18:36 πŸ”— anomie It's the ambiguity cause by using "kilo" that bothers me.
18:36 πŸ”— anomie *caused
18:37 πŸ”— anomie Though, I remember there was also a time where MB could mean 1,024,000 bytes.
18:39 πŸ”— aaaaaaaaa I think it was always 2e20, and people just couldn't be bothered to do the math
18:39 πŸ”— anomie My point is, whenever I see GB, or Mbps, or kb, etc., I'd like to know exactly how many bytes are being talked about. Further context shouldn't be required.
18:41 πŸ”— aaaaaaaaa Probably not, but it takes force to overcome momentum and I doubt most people care because magnitude usually matters more than exactness.
18:41 πŸ”— anomie Yeah.
18:42 πŸ”— anomie In any case, I'm glad that for now I can assume that most HDD vendors use the SI one, and most everyone else doesn't.
18:42 πŸ”— anomie I'll still always be pedantic enough to use decimal kilobytes though.
18:43 πŸ”— aaaaaaaaa or start calling them kibibytes, or whatever the name is
18:43 πŸ”— anomie I'm really sure I like that term.
18:44 πŸ”— anomie I mean, most people will just hear "kilobytes" anyways.
18:44 πŸ”— anomie What do ram manufacturers use?
18:44 πŸ”— aaaaaaaaa base 2
18:45 πŸ”— anomie All right.
18:46 πŸ”— aaaaaaaaa usually almost anything measured in "bytes" is base 2, except hard disks, anything else is usually base 10
18:46 πŸ”— anomie In any case, I'll always dream of a day when an average Windows user plugs in a 1TB HDD, that windows will tell him it's 1TB, rather than 931.3226GB.
18:46 πŸ”— wyatt8740 and OS X and anything in linux that uses glib use base 10 because they're dumb
18:46 πŸ”— anomie s/dump/correct
18:46 πŸ”— anomie *dumb
18:46 πŸ”— wyatt8740 I had to recompile my file manager in linux with some tweaks to make it correct in base 2
18:47 πŸ”— anomie …
18:47 πŸ”— anomie wyatt8740: Can we stop before the flamewar happens?
18:47 πŸ”— aaaaaaaaa oh yeah. I've had things change sizes on me before when partitioning vs formatting
18:47 πŸ”— wyatt8740 I didnt realize anyone actually used the 'drivemaker's kilobyte'
18:48 πŸ”— wyatt8740 https://xkcd.com/394/
18:48 πŸ”— anomie wyatt8740: The IEC does, the IEEE does.
18:48 πŸ”— anomie It's an SI unit.
18:48 πŸ”— wyatt8740 IEC created a standard for base 2
18:48 πŸ”— anomie wyatt8740: Wut? http://physics.nist.gov/cuu/Units/binary.html
18:48 πŸ”— aaaaaaaaa right, but I believe the disk makers switched first and the IEC had to clean up the mess or something like that
18:49 πŸ”— anomie aaaaaaaaa: Can you show me? That sounds really interesting.
18:49 πŸ”— wyatt8740 no, drivemakers abuse the SI standard because it's more bytes of storage on the label and less that computers actually see
18:49 πŸ”— anomie Regardless, they were simply using SI prefixes correctly.
18:49 πŸ”— wyatt8740 even OS X uses base 2 for all the CLI programs because that's the way it's always been done
18:50 πŸ”— anomie wyatt8740: It's retarded though.
18:50 πŸ”— wyatt8740 not denying that SI did make the standard, just saying SI was wrong to do so IMO :p
18:51 πŸ”— anomie Being the way it was done first doesn't make it right.
18:51 πŸ”— anomie "Faced with this reality, the IEEE Standards Board decided that IEEE standards will use the conventional, internationally adopted, definitions of the SI prefixes. Mega will mean 1 000 000, except that the base-two definition may be used (if such usage is explicitly pointed out on a case-by-case basis) until such time that prefixes for binary multiples are adopted by an appropriate standards body. "
18:52 πŸ”— aaaaaaaaa either way, all the old dogs and greybeards will die off eventually and the great SI/IEC utopia will not be stopped.
18:52 πŸ”— anomie I hope so.
18:52 πŸ”— wyatt8740 1000/8 = 125. 125/8 = 15.625. 15.625 / 8 = 1.953125. Where in base 2, 1024/8=128. 128/8 = 16. 16/8 = 2.
18:52 πŸ”— wyatt8740 IMO whole numbers make more sense :p
18:52 πŸ”— anomie aaaaaaaaa: I think you might be underestimating the influence of the things people already use.
18:53 πŸ”— primus104 has joined #archiveteam-bs
18:53 πŸ”— anomie As long as windows doesn't change, I don't think very much else will.
18:53 πŸ”— wyatt8740 people already use windows (most of them, not me personally)
18:54 πŸ”— wyatt8740 it'd be better if windows would just shove a lowercase 'i' between K and B.
18:54 πŸ”— wyatt8740 :p
18:54 πŸ”— anomie Still, I think windows could at least start using KiB, MiB, GiB, etc.
18:54 πŸ”— anomie wyatt8740: Yes, I agree.
18:54 πŸ”— anomie I don't care which one is used more, as much as I wish they could be distinct.
18:55 πŸ”— wyatt8740 if computers did calculations in base 10 I wouldn't mind either :p
18:55 πŸ”— wyatt8740 but they don't
18:56 πŸ”— anomie Don't do calculations in base 10 then.
18:58 πŸ”— anomie KiB will always remain useful at a lower level, beyond the reach of common abstractions.
18:58 πŸ”— aaaaaaaaa who doesn't know that .1 + .1 + .1 != .3
18:58 πŸ”— anomie Just a step above where engineers once spoke of "bauds".
18:58 πŸ”— aaaaaaaaa totally obvious
18:59 πŸ”— aaaaaaaaa baud actually measures something different
18:59 πŸ”— anomie aaaaaaaaa: Actually… lemme try something.
18:59 πŸ”— anomie CL-USER> (+ 0.1 0.1 0.1) | A))
18:59 πŸ”— anomie 0.3
19:00 πŸ”— anomie aaaaaaaaa: Apparenlty Common Lisp doesn't. ;)
19:00 πŸ”— anomie aaaaaaaaa: Do you have any more floating point fuckery I could try?
19:02 πŸ”— aaaaaaaaa they probably round or the actually equality measure might be false or various behind the scenes things might be happening.
19:03 πŸ”— anomie aaaaaaaaa: Should I try using smaller amounts?
19:03 πŸ”— aaaaaaaaa I don't remember any off hand, but a lot of operations give odd results, especially if you store an intermediate variable.
19:04 πŸ”— anomie Here's one.
19:04 πŸ”— anomie CL-USER> (+ 0.0001 0.0001 0.0001)
19:04 πŸ”— anomie 2.9999999e-4
19:10 πŸ”— aaaaaaaaa http://www.lahey.com/float.htm
19:11 πŸ”— aaaaaaaaa Those examples are in fortran, but you'd probably get the gist.
19:12 πŸ”— anomie I just realized some people still use fortran.
19:12 πŸ”— anomie Which isn't a bad thing, I guess. Fortran is *still* amazingly well optimized.
19:41 πŸ”— wyatt8740 anomie: I have a RS232 terminal, I am perfectly aware what bauds are :p
19:41 πŸ”— wyatt8740 also, I do calculations in base 10. But I dont want my computer lying to me about how big files are
19:43 πŸ”— wyatt8740 (though the flyback transformer in my terminal died last week so it's currently out of commission)
20:09 πŸ”— schbirid has quit IRC (Quit: Leaving)
20:49 πŸ”— PurpleSym has quit IRC (Remote host closed the connection)
20:55 πŸ”— anomie wyatt8740: I… I'm not old enough. Can you explain please?
20:57 πŸ”— c_b has joined #archiveteam-bs
21:11 πŸ”— wyatt8740 anomie: baud?
21:12 πŸ”— wyatt8740 I'm 18 btw
21:12 πŸ”— wyatt8740 so I'm not really old enough either.
21:12 πŸ”— wyatt8740 in RS232 baud is the number of bytes that can be sent per second
21:12 πŸ”— wyatt8740 *characters
21:12 πŸ”— wyatt8740 so that usually equates to bytes but not always (some terminals used 7 bits per character I think)
21:13 πŸ”— wyatt8740 whoops
21:13 πŸ”— wyatt8740 im wrong
21:13 πŸ”— wyatt8740 it's bits per second
21:14 πŸ”— wyatt8740 so 19200 baud means you can send up to 19200 bits per second (or 2400 bytes, or 2.34 KiB/2.4KB)
21:15 πŸ”— wyatt8740 19200 baud is the maximum speed of my terminal
21:15 πŸ”— wyatt8740 and it goes all the way down to 150 baud
21:15 πŸ”— wyatt8740 at lower speeds like that or even 1200 baud you can literally see lines being drawn when you use a ncurses program
21:28 πŸ”— anomie Yeah.
21:29 πŸ”— anomie 1200 baud is when you drop vim/emacs and start using ED.
21:29 πŸ”— anomie But what is the flyback transformer?
21:29 πŸ”— anomie What is RS232?
21:34 πŸ”— aaaaaaaaa Try wikipedia. But in all seriousness, flyback transformers are common in CRTs and RS-232 is a standard for serial communication.
21:35 πŸ”— pikhq RS232 is not merely common but damned near ubiquitous even today.
21:35 πŸ”— pikhq Admittedly you're not likely to be exposed to it as an end user unless you're doing device development of some form.
21:35 πŸ”— aaaaaaaaa RS-232 was used for almost everything I can think of, except printers, before USB took over on PCs
21:36 πŸ”— pikhq (the major use case for it these days is to get a console on various devices. Say, tinkering with the firmware on your TV.)
21:37 πŸ”— anomie Is it the original serialbus?
21:37 πŸ”— aaaaaaaaa yeah, or industry stuff
21:37 πŸ”— pikhq anomie: Yep.
21:37 πŸ”— anomie Ah.
21:37 πŸ”— pikhq Though it's not a bus.
21:37 πŸ”— anomie Doesn't it have 9 pins, if I remember right?
21:37 πŸ”— anomie Five on top, four on the bottom?
21:37 πŸ”— Baljem although technically that's just async serial, commonly called UART - RS232 specifies signalling levels that are pretty antiquated (nominally +/- 12V) and you won't find real RS232 on things like embedded debug ports
21:38 πŸ”— pikhq RS-232 specifies a 25 pin connector, but most stuff uses a 9 pin connector or something.
21:38 πŸ”— pikhq Right, yeah, you'd need extra circuitry to get real RS-232 out of debug ports.
21:38 πŸ”— Baljem the 9-pin variant was an IBM attempt to save money. RS232 itself defined a 25-pin pinout, including a secondary circuit and additional handshaking
21:39 πŸ”— anomie Wow…
21:40 πŸ”— Baljem (there's also a difference between 'baud' and 'bits per second', which is something like symbols vs. bits - the baud rate is the number of times the signal can change state per second, but each state might convey multiple bits - although quite where that lies on the common-usage vs. official-usage vs. pedantic-crap spectrum I'm not sure)
21:41 πŸ”— pikhq RS-232 is fairly nice for stuff because it's relatively simple to support (and something that pretty much anyone can get access to)
