or has the initial enthusiasm worn off? 00:26:01 I've been wondering if it's good for proving things TC but few languages seem to have the right primitives 00:26:09 ais523: no, I'm still enthusiastic about the M:tG proof 00:26:14 I should write that down 00:28:15 so should I 00:28:26 I'm thinking about getting back to it, the I/D machine was a bit of an abstraction 00:28:47 I've already written a couple of background pages about it but may want to throw them out and start again, I think I'm aiming at the wrong level of abstraction for the readers I want 00:28:56 but they helped me to get my thoughts in order (and find the tournament rules issue) 00:29:14 which tournament rules issue? 00:29:26 do you mean the comprehensive rules problem about the infinite loops? 00:33:11 no, slow play rules 00:33:12 I/D is actually quite good for virtual machines 00:33:26 that say you aren't allowed to continue a loop without knowledge of the iterations and expected end state 00:36:15 [[TLOWScript]] https://esolangs.org/w/index.php?diff=54402&oldid=54401 * Hanss314 * (+115) 00:40:44 -!- ais523 has quit (Quit: sorry for my connection). 00:40:59 -!- ais523 has joined. 00:42:56 what is the I/D machine? 00:45:20 https://esolangs.org/wiki/I/D_machine 00:46:11 or as a one line summary: a language with data pointer (initially 0) and unbounded RAM of unbounded elements (initially all 0) and two commands; I increments the target of the data pointer, D assigns the value in the data pointer's target back to the data pointer; the program repeats forever in an implicit loop 00:46:35 I love that you can fully specify it in one line of IRC 00:49:19 the winner for the shortest specification may go to The Waterfall Model, which can be fully specified in 4 bytes of [[e:Jelly] : +"Ṃẞ (Jelly uses an encoding where Ṃ and ẞ are each single bytes) 00:49:40 ais523: but doesn't that cheat by not including the loop? 00:49:59 wob_jonas: the Jelly impl? that's what the ß (or is it ẞ) means 00:50:06 ok 00:50:25 "run the main program recursively", so putting it at the end of the program gives you an infinite loop via tail-recursion 00:50:37 looking at this I'm very suspicious I've used the wrong case of ß, I'll have to fix that at some point 00:51:00 -!- tromp has quit (Remote host closed the connection). 00:51:11 the other commands are + meaning "add", " meaning "corresponding elements", and Ṃ meaning "minimum" 00:51:52 and it takes minimum of rows by comparing them lexicographically? 00:51:57 yes 00:52:02 so only the first element actually gets compared 00:52:48 nice 00:52:48 in this case, the "corresponding elements" are of the minimum and of the full matrix 00:53:03 yes, that makes sense 00:53:04 so the first element of the minimum gets added to the first row of the matrix, the second element of the minimum to the second row of the matrix, and so on 00:53:28 golfing languages are great, they just give you a big mix of nouns and verbs and adjectives and the like 00:53:43 then you string them together and it figures out what you mean from context (with rules that are objectively defined but often quite complex) 00:54:07 not all golfing languages are like that, but yeah 00:54:31 looks like it is ß that should be used 00:54:47 wob_jonas: right, others have entirely meaning sets for different contexts, Japt for example 00:54:49 I don't like that as much though 00:54:57 a good golfing language is like a good natural language 00:55:04 huh? 00:55:08 entirely meaning sets? 00:55:30 like, the code determines the context of any particular command via running the code up to it 00:55:40 then what it does depends on the context and the various possible meanings don't need to be correlated at all 00:56:59 . o O ( garden path programming ) 00:58:05 so, for example, f in Japt will act as an array intersection operation if run on an array (with a few other options), but if you give it a number instead, it'll do a floor operation 00:58:08 those have nothing in common 00:59:31 . o O ( the result will never be larger than the input(s) ) 01:00:11 in Jelly, Ḟ will floor a number or floor every element of an array; f will take the intersection of arrays, and treat numbers in its argument as an array of the integers from 1 to the number inclusive 01:00:27 A short AWK program to change multiple blank lines into a single blank line: x+(x=NF) 01:01:00 in sed you could write it as /^$/d I think 01:01:08 or, hmm 01:01:15 zzo38: wtf 01:01:18 that changes multiple newlines into a single newline 01:01:22 which is a different operation 01:03:18 ais523: will that Jelly program implementing Waterfall use bignums? because I don't think fixed sized numbers are enough to make Waterfall reasonably usable, with the exponential slowdown 01:03:54 yes, bignums 01:04:02 also that language is exponentially slower than Waterfall 01:04:15 (Jelly uses bignums by default; it has a variant called M which uses computable reals) 01:04:22 lol 01:04:29 computable reals? 01:04:33 has that ever been implemented? 01:04:57 ais523: Yes, that deletes blank lines, which is different to what I wrote. In sed if there is a command to match a regular expression across multiple lines then you can do what I mentioned 01:05:13 I mean, there's already very few implementations that can do arithmetic on arbitrary algebraic numbers 01:05:33 zzo38: can you do it in sed with a comma thingy? 01:05:44 like /^$/,/^$/d or something 01:05:57 wob_jonas: there are drop-in computable reals libraries for many languages 01:06:28 although they tend to struggle when comparing them, if two computable reals are actually equal then a comparison between them tends to cause an infinite loop 01:06:41 right 01:06:44 it's easy without comparing 01:06:46 unless they're known to be ints or rationals or something similarly easy to compare 01:08:09 wob_jonas: That doesn't work (I tried it). 01:08:42 zzo38: yeah, but something like that maybe? with an added a command or something 01:08:48 I'm not good at sed 01:09:39 I am not that good at it either, but I do know awk, which is why, I wrote the program in awk instead. 01:09:50 that program looks crazy 01:10:01 that expression is applied as a condition for an implicit print, right? 01:10:18 Yes it is applied as a condition for an inplicit print. 01:10:20 and NF tells the number of fields 01:10:36 Yes. 01:11:44 I see, that actually makes sense 01:36:30 anyway, I still say that the slow play stuff doesn't matter, the opponent just has to call a judge if he can't figure out how the loop works 01:37:36 `` printf "foo\nbar\n\nbaz\n\n\n\nquux\n" | sed -e 's/^$/x/;tx;x;s/.*x.*//;Ty;p;:y;x;p;d;:x;H;d' 01:37:37 foo \ bar \ \ baz \ \ quux 01:38:07 It really should be a lot simpler, but for some reason the simpler things weren't working. sed can be a little subtle when it comes to newlines. 01:38:49 fizzie: nice 01:39:40 how about tr \\n: :\\n | sed 's/:::*/::/ | tr \\n: :\\n 01:39:48 no! damn typo 01:39:53 tr \\n: :\\n | sed s/:::*/::/ | tr \\n: :\\n 01:40:11 but the regex needs to be a bit more complicated if you want to accept lines with only whitespace as blanks 01:40:17 still, I think it's workable 01:40:24 and I should really escape that star 01:40:28 tr \\n: :\\n | sed s/:::\*/::/ | tr \\n: :\\n 01:42:24 Sounds plausible, and pretty clever. 01:42:37 My sed thing basically appends a 'x' marker to the hold space on every empty line, and on non-empty lines prints out an extra newline before the original contents. 01:42:52 (Iff there's an 'x' in the hold space, that is.) 01:43:46 `` printf "foo\nbar\n\nbaz\n\n\n\nquux\n" | tr '\n:' ':\n' | sed 's/:::*/::/g' | tr '\n:' ':\n' 01:43:47 hmm 01:43:47 foo \ bar \ \ baz \ \ quux 01:44:58 (I wanted it to just copy append empty lines to the hold space and then s/\n\n*/\n/ the hold space before prepending it, but I think the hold space operations do some implicit newlining, or something.) 01:45:23 sed is a terrible programming language 01:49:00 -!- oerjan has quit (Quit: Nite). 01:51:42 -!- boily has quit (Quit: SQUISHY CHICKEN). 02:00:20 -!- tromp has joined. 02:04:01 [[TLOWScript]] https://esolangs.org/w/index.php?diff=54403&oldid=54402 * Hanss314 * (+27) 02:04:33 -!- tromp has quit (Ping timeout: 240 seconds). 02:32:06 -!- variable has joined. 02:34:43 -!- tromp has joined. 02:39:09 -!- tromp has quit (Ping timeout: 246 seconds). 02:42:53 -!- sprocklem has quit (Ping timeout: 240 seconds). 02:45:14 -!- sprocklem has joined. 02:47:32 -!- variable has quit (Quit: /dev/null is full). 02:53:56 -!- variable has joined. 03:00:00 -!- Naergon has quit (Remote host closed the connection). 03:06:47 -!- tromp has joined. 03:11:25 -!- tromp has quit (Ping timeout: 256 seconds). 03:34:19 -!- sleffy has joined. 03:46:04 -!- tromp has joined. 03:50:46 -!- tromp has quit (Ping timeout: 264 seconds). 04:08:45 -!- sleffy has quit (Ping timeout: 264 seconds). 04:15:43 -!- tromp has joined. 04:17:19 -!- wob_jonas has quit (Quit: http://www.kiwiirc.com/ - A hand crafted IRC client). 04:20:09 -!- tromp has quit (Ping timeout: 260 seconds). 04:53:21 -!- sleffy has joined. 04:53:47 -!- tromp has joined. 04:58:10 [[Incident]] https://esolangs.org/w/index.php?diff=54404&oldid=51822 * Ais523 * (+628) /* Computational class */ explain the TCness proof (both that the pretty-print half is on the talk page, and that the translation from slightly restricted Minsky machines is in the repo; also mentoin the TAFMl1 connection) 04:58:31 -!- tromp has quit (Ping timeout: 256 seconds). 05:23:33 -!- variable has quit (Quit: Found 1 in /dev/zero). 05:55:21 -!- chal_ has joined. 05:59:01 -!- doesthiswork has quit (Quit: Leaving.). 05:59:44 -!- chal_ has quit (Ping timeout: 260 seconds). 06:03:39 -!- tromp has joined. 06:07:57 -!- tromp has quit (Ping timeout: 240 seconds). 06:11:18 -!- variable has joined. 06:14:28 -!- ais523 has quit (Quit: quit). 06:24:57 -!- sleffy has quit (Ping timeout: 240 seconds). 06:34:37 -!- tromp has joined. 06:38:49 -!- tromp has quit (Ping timeout: 256 seconds). 07:00:44 I did this in a C program in order to indent output lines: printf("\n%*s",x,""); How common is such a thing in a C code?

And what is BAL? 08:40:01 I dont know... 08:40:13 You could write it that way, but Dirac notation look like it works better in this case. 08:41:00 Just to clarify, what is Dirac notation? 08:42:19 Dirac notation is also described in Wikipedia, they could probably explain better than I do 08:43:52 I already looked. It started talking about Bra-ket notation!!!!! And im not a physicist! 08:44:32 shachaf: Financial state vector is all of the accounts, like you normally do in accounting.

15:58:58  I looked in dmesg and found the message "sr0: CDROM not ready.  Make sure there is a disc in the drive." several times even though I am not trying to use the CDROM, as well as a message that says "sd 3:0:0:0: [sda]  Add. Sense: Unrecovered read error - auto reallocate failed". Nevertheless the computer seems to work. Why are these error messages in there?
15:59:46  zzo38: maybe some process is trying to use sr0 even though you don't?
15:59:52  uh wait
16:00:03  that second message about sda is more worrysome
16:00:15  is sda a hard disk you have data on?
16:00:23  that might be bad
16:01:01  your disk or disk controller might be dying. obviously that's unpredictable, it could die in a minute or last for years.
16:01:17  but I'm always worried if I see that kind of IO error message about a hard disk
16:01:32  (not when I see it for a removable media like a floppy or CD, there it's normal)
16:02:01  (the floppy or CD can get unusable too, but a hard disk costs more than a hundred times as much as a floppy or CD)
16:04:17  Yes it is a hard disk, although smartctl does not report any problem with any SMART attributes. It reports temperature as 29, but I do not know what temperature should be proper.
16:04:17  the CDROM message is irrelevant, I'd ignore it unless you have other problems with the optical drive near the same time
16:04:38  temperature 29? what is that measured in? degrees celsius?
16:05:11  I think it is Celsius
16:05:46  (It says "Temperature_Celsius")
16:05:46  wob_jonas: Yes, for Example the Linux-Kernel would probably suck if written in C++
16:05:49  Well
16:05:56  Would depend on what Libraries You include
16:06:07  The Kernel probably will not have the normal stdlibs
16:06:19  And SymbianOS is not _that_ bad either
16:06:25  Being fully C++
16:06:32  APic: that's a matter of an age old debate, and, in any case, the kernel is already written in a really strange dialect of C, so if it were written in C++, then it would be written in a strange dialect of C++ too
16:06:45  But i still liked very much when Nokia released the OpenC-Stuffs for the E90 back then
16:06:58  Where You could do Unix-C-Stuffs like i was used to
16:06:59  I don't do kernel programming anyway, and I have no problem with some userland programs or libraries being written in C either
16:07:05  True
16:07:05  I'm not doing C++ because I hate C or anything
16:07:13  Good
16:07:18  Hate is generelly a bad Feeling
16:07:21  Or Attitude
16:07:23  I'm using C++ because it's a great tool and I can accomplish a lot with it, including at work
16:07:28  Yah
16:07:33  oh, I do have hate. it's just not directed at C
16:07:44  there are better targets
16:09:30  Do you know what temperature is reasonable for the hard drive? (It says 29 under VALUE, and 50 under WORST, and 0 under THRESH)
16:10:27  I'm not a hardware guy, so I don't really know, but I think anything between 10 and 50 degrees celsius is definitely fine, anything above 100 degrees celsius is bad, and for the rest I have no idea
16:11:07  as long as you make sure to occasionally vacuum the dust accumulated in the computer
16:12:52  I do not have a special vacuum cleaner for use with the computer (I have been trying to acquire one).
16:14:28  You don't need a special vacuum cleaner. An ordinary vacuum cleaner mostly works, except possibly for the cooling grills and fans.  For there, a vacuum cleaner doesn't help, but you might use either compressed air cylinders or an electric compressed air blower.

16:19:41  The other Harddisk does not seem to deliver that Information to SMART
16:20:46  What I have read is that Seagate stores the actual temperature in VALUE and WORST on attribute 194 (rather than the normalized value like it is supposed to do), and it does not have attribute 190
16:25:32  Listen to hardware guys you trust, not me. I'm not good at hardware, my advice there is worthless.
16:26:19  OK, but I don't know any hardware guys
16:27:15  wob_jonas: a few years ago one of my friends was horrified to discover that a) I put together my own PC, and B) I somehow was using far fewer screws than should be possible

17:15:57  there are all sorts of more sophisticated methods, but I don't bother
17:16:31  except that if you have some really important files, like the stereotypical thesis you're writing or thesis your spouse is writing, then make copies of those often and distribute copies everywhere

17:36:53  What version of perl do you need?
17:40:09  zzo38: that program was published in 2011, so perl 5.14 should definitely be enough, but I'd guess perl 5.10 might work too.
17:40:31  and although it isn't mentioned here, I later started to compress the tarballs with 7z instead of gzip
17:41:26  but be careful, I don't really use the best backup practices
17:41:33  you could even say I'm careless
17:41:45  it might be better to ask someone more careful with this stuff
17:42:25  Although 7-Zip already includes the list of files anyways, so then I wouldn't know why you will also need tar?
17:42:52  7-zip doesn't save unix attributes like file owner and group and permissions and symlinks
17:43:01  I need to save those for a full system backup
17:43:32  Yes, I should need to save permissions and symlinks
17:43:49  also tar recognizes hard links when you archive all the fifty hard links to the git binary that git installs
17:44:05  it doesn't recognize them when they're in separate archives, so the backup is a bit lossy that way
17:46:50  also, I make the backup from a non-recursive bind mount of the root file system, so that other mounts (including the one that covers the bootstrap files in /dev etc) don't distract the backup
17:48:25  I believe on if you want a working full backup of Linux, the device file /dev/console is important, it can be used before the devtmpfs is mounted over /dev , although this applies only if you're not using an initrd, which is getting rare these days
17:48:43  still, it's better to back up the files that are there in /dev rather than not back them up
17:48:51  and a bind mount lets me do that
17:49:35  But some of them are devices is it possible to back up such files? And, what is a bind mount?
17:56:08  For the devices, you just back up the meta-information stored on the file system, not the actual device, as in what device /dev/null and /dev/zero and /dev/console and /dev/fd0 etc refer to, not the actual contents of those devices. tar won't try to read the contents of the device files, just like how it doesn't try to read what a symlink points to
17:56:08  .
17:57:11  A bind mount is a somewhat modern linux feature (although other unixes have similar) where you create a mount that isn't backed by a file system on a device, but just reflects (a subdirectory on) an existing mount in a different place on the file system. See the --bind option in man mount
17:58:39  So eg. I create a bind mount with (mount --bind / /mnt/safe/root) then /mnt/safe/root/bin/sh will point to effectively the same file as /bin/sh , but this is not recursive, so if I have another file system mounted under /mnt/safe/kond then /mnt/safe/root/mnt/safe/kond will show the directory on the root file system, not the other file system that's
17:58:39   mounted there in /
17:59:10  There's also a recursive bind mount with the mount --rbind option that does reflect the other mounts, but that's not what I want here.
17:59:34  Obviously if you have data on multiple file systems, then you may want to back those up too.
18:02:52  O, that's how it works. I do not have multiple file systems
18:04:34  Is there a way to perform incremental backups while the system is running?
18:11:32 <\oren\_> I back everything up to DVD
18:18:33 -!- SopaXorzTaker has quit (Remote host closed the connection).
18:34:47  zzo38: performing backups while the system is running is much more difficult, because you have to be very careful not to end up in an inconsistent state, like where some data is moved from one directory to another, and you back up both directories when the data is in the other.
18:35:47  There are application-specific tricks (eg. subversion gives like four different ways to create a consistent copy of a repository), and there's modern solutions supported by the kernel and the file system, but I don't know how these work and I'm not the right person to ask.
18:37:19  For my home machine, I already turn off the computer often, so I can afford to stop most other processes when I'm creating the backup (the tarballs to a hard disk that is; I can run the system while I write the tarballs to DVD), and I can manage small but important files (like the stereotypical thesis) in a case by case basis (eg. I don't work on t
18:37:19  he thesis while I make a backup copy of it).
18:37:48  \oren\: ok, but what's your process of backing up everything to DVD? can you be a bit more specific?
18:41:39  Can you lease the file while making a backup of it?
18:42:13  (If the lease is broken, it can remember that it has not backed up that file and try again later)
18:43:40 <\oren\_> wob_jonas: I just burn a new set of dvds aveyr few months
18:45:06  Or will leasing the files not help?
18:45:11 <\oren\_> I don't really have any large files so my whole home directory fits on 3 DVD's
18:45:29 <\oren\_> ... used to fit on only one tho
18:46:36 <\oren\_> I keep them in envelopes with the date I burned them written on them
18:47:10  All of the files on my computer might fit on three DVDs, but I have not tested this yet

18:51:00  zzo38: you'd have to lease all files (and all directories) at the same time, and if that was possible, it's more or less than same as stopping or suspending the system because nobody can write anything
18:51:55  \oren\: do you store some of the backup DVDs in places other than the home where the computer is?
18:52:19  My backups are in a different country than the computer.
18:52:26  I think about a quarter of my backups is photos, and this ratio will just increase as I'm doing more and more photography
18:52:33  fizzie: nice
18:53:06  wob_jonas: TBH, it's really just an artefact of the fact that we already had a safety deposit box in a bank in Finland.
18:53:10 <\oren\_> wob_jonas: no but I usually take my computer on trips, but don't take the dvd's. I have off-site backups onto AWS
18:53:25  (It does mean the off-site copy is only updated about once a year.)
18:57:17 <\oren\_> actually now I think about it I could put some dvd's in the garage, which probably wouldn't burn even if the whole house did

18:57:44  fizzie: sure, and you could say that my off-site backups are an artifact of having moved away from my parents' house but still storing some stuff there

19:56:24  Is rsync suitable to make a backup on the DVD?
19:57:19  [[Hatemath]]  https://esolangs.org/w/index.php?diff=54409&oldid=54387 * BMO * (+410) implemented the language & changed commands-listing to a wiki-table.
19:57:26  (Since I already have rsync in my computer)
20:01:42  And what issues will there be with recording on DVD while the system is running? The man page for wodim says, for the information about the -dummy option, "It is recommended to run several tests before actually writing to a Compact Disk or Digital Versatile Disk, if the timing and load response of the system is not known."
20:04:10  Also, which DVDs are better, -R or +R? I have -R (and as far as I know the optical drive on my computer can record on DVD-R), but I don't know what is better
20:08:16  Anyways, if there are any of my public files that you want copies of (including clones of Fossil repositories), you may make those copies if you wish.
20:26:51  copumpkin: at least you can replace USB cables without replacing the whole charger hth
20:29:07  zzo38: that's much less of a problem these days than it used to be when computers were small and your whole computer had 128 MB of RAM and so CD burners couldn't afford to have hundreds of megabytes of buffer RAM right on the board. these days you don't have to worry about burning DVD while the system is running.
20:30:02  zzo38: there's still some anecdotal evidence that it might be worth to burn disks at slower speed than the drive and disk are capable of, not because the burning fails, but because the disk might last longer, but it's hard to tell whether this actually matters
20:30:52  zzo38: as for -R versus +R disks, these days it doesn't matter at all. that started as some sort of two standards by two competing companies, but these days every drive and every software is compatible with every variant.
20:31:28  zzo38: and no, I don't think rsync is suitable for writing directly on the DVD
20:33:16  For writing DVD or CD, I recommend first collecting a copy of what you want to backup to hard disk, which is the phase where it matters that other processes don't modify the source, then later you can write from that copy to DVD at leisure, for which I recommend http://libburnia-project.org/ if you're doing the burning on a linux system
20:34:16  that's a set of command-line tools for writing (and reading) CD and DVD of all kinds
20:36:01  so I create backup tarballs on hard disk while the system is running, then write the tarballs onto DVDs

20:40:45  This isn't the only software that can burn DVDs, and you can use others, it's just what I recommend.

21:28:00  Would it be possible to design a language to be turing complete when it's only data type is a set
21:28:13  (without self modification. self modification makes anything turing if you try hard enough lol)
21:36:13  sure
21:36:14  moony: sure, why not
21:36:14 <\oren\_> moony: you can represent any integer as a set
21:36:50  `hi \oren\_
21:36:51  Hi \oren\_. Horen\_.
21:37:21  I'm just looking into how such a language could be minimized, and what would the minimum instruction set for a set only language be
21:39:05  moony: can you have labels and goto? if so, then probably just have a two-counter Minsky machine, and call the numbers "sets", where instead of increasing, you form a singleton set, and instead of decreasing, you take an arbitrary element of the set but test if it's empty
