00:00:04 <Vorpal> elliott, asteroids. Don't think I actually played that
00:00:16 <Vorpal> elliott, isn't it like Ambrosia's Maelstrom?
00:00:19 <elliott> Vorpal: It's that thing where you're a triangle and there are hollow rocks around you.
00:00:26 <elliott> http://upload.wikimedia.org/wikipedia/en/1/13/Asteroi1.png
00:00:32 <elliott> And you spin around shooting them.
00:00:53 <Vorpal> elliott, do large ones break into smaller when hit?
00:01:04 <elliott> Yes.
00:01:06 <Vorpal> elliott, if so it is exactly like maelstrom, except with worse graphics
00:01:19 <elliott> To be fair, it almost certainly predated Maelstrom by a long, long time :P
00:01:24 <elliott> (1979)
00:01:25 <Vorpal> elliott, yes quite
00:01:31 <Vorpal> elliott, you played the latter?
00:01:38 <elliott> Maelstrom is a 1992[1] clone of Asteroids with an improved graphics and interface.[2][3] Many of Ambrosia's subsequent shareware titles followed in a similar formula.
00:01:40 <elliott> I haven't.
00:01:50 <Vorpal> elliott, http://en.wikipedia.org/wiki/File:Maelstrom_screenshot.png
00:01:56 <elliott> I have used exactly two Macs in my life for more than a few seconds, I think.
00:02:10 <elliott> One was someone else's eMac I used once, the other is my iMac.
00:02:16 <elliott> Although to be fair it's rapidly approaching three.
00:02:19 <Vorpal> emac... what one was that now again?
00:02:31 <elliott> Vorpal: you know the original iMac?
00:02:33 <elliott> Like that, but white.
00:02:39 <Vorpal> eh
00:02:57 <Vorpal> elliott, I do know the original imac. And it came in a snow white edition later. And flower power
00:03:29 <elliott> http://www.extensions.in.th/post/emac/emac2.jpg
00:03:34 <elliott> It was short for "education Mac".
00:03:43 <elliott> The eMac, short for education Mac, was a Macintosh desktop computer made by Apple Inc. It was originally aimed at the education market, then available as a cheaper mass market option over Apple's second generation iMac. The eMac design closely resembled first-generation iMacs. It sports a PowerPC G4 processor significantly faster than the older iMac's G3 processor, and a larger 17" flat display.

00:04:07 <Vorpal> that looks OS-X-ish
00:04:13 <elliott> Naw.
00:04:15 <elliott> OS 8, OS 9.
00:04:19 <Vorpal> on the image it does
00:04:20 <elliott> Although it did last for several years under OS X, yes
00:04:22 <elliott> *yes.
00:04:25 <elliott> Until 2005.
00:04:26 <Vorpal> ah
00:04:28 <elliott> Well, 2005/2006.
00:04:30 <elliott> But nobody bought it.
00:04:45 <elliott> Vorpal: Anyway we've ruled out MMO because MMO physics, synchronisation and servers sounds like FUN (read: pain).
00:04:56 <elliott> Vorpal: So it's either going to be a deathmatch game or [insert other thing here].
00:05:12 <Vorpal> elliott, I know a guy good at MMO
00:05:14 <Vorpal> a swede
00:05:21 <Vorpal> elliott, I think he went by the name notch
00:05:24 <Vorpal> you may ask him
00:05:29 <elliott> Vorpal: You have a strange definition of good.
00:05:33 <Vorpal> elliott, XD
00:05:39 <elliott> Vorpal: Also of MMO, Minecraft servers rarely have /that/ many people on them :P
00:05:54 <Vorpal> elliott, indeed. AND IT IS ALREADY BUGGY!

00:06:01 <Sgeo_> BZFlag!
00:06:11 <elliott> Vorpal: I feel kinda bad doing copyleft ...
00:06:23 <Sgeo_> BZFlag servers have lots of people on them!
00:06:23 <Vorpal> elliott, alt: it is MMO for minecraft
00:06:27 <Vorpal> (massive there = 10)
00:06:36 <Vorpal> elliott, XD
00:06:38 -!- Sgeo has quit (Ping timeout: 240 seconds).
00:06:41 <Sgeo_> (and lots of cheating, but I digress)
00:06:48 <Vorpal> elliott, and copyleft rocks!
00:06:53 <Vorpal> elliott, you are seeing the light
00:07:01 <elliott> Vorpal: (As in, the game will be released under "sorta-copyleft": it's copyleft, except you can't distribute anything more than patches in public, basically.)
00:07:10 <elliott> Because otherwise people could just post the entire source :P
00:07:28 <Sgeo_> elliott, you're turning evil?
00:07:43 <elliott> Sgeo_: Yes; mwahahaha, look at my fangs.
00:07:59 <elliott> So evil that I'm considering putting it on a torrent site as a potential solution for slow sales.
00:08:03 <elliott> MWAHAHAHAHA
00:08:08 <elliott> (Note: Phantom_Hoover__ is not nearly as insane as me.)
00:08:30 <Phantom_Hoover__> elliott, of the two of us, who thought of the negative mass engine?
00:08:35 <Vorpal> elliott, hm "On July 5, 2006, an "educational configuration" of the iMac Core Duo was introduced, discontinuing and replacing the entire eMac line. The new iMac has a Combo drive rather than a SuperDrive and a smaller hard disk of 80 GB."
00:08:40 <Vorpal> elliott, this sound feeble
00:08:54 <Vorpal> elliott, I mean, for education you want power machines
00:09:00 <elliott> Vorpal: Are you being serious.
00:09:01 <elliott> Phantom_Hoover__: Well, okay, you.
00:09:17 <elliott> Phantom_Hoover__: But I'm crazy enough to want to release the whole thing as free-as-in-beer and open source after sales trickle off!
00:09:33 <Phantom_Hoover__> Pssht, Notch thought of that.
00:09:51 <Vorpal> elliott, yes quite. We all have Core 2 Quad or better in most labs at university. (so there are a few old ones with p4 and CRT iirc, but they are an exception)
00:09:59 <elliott> Vorpal: education != uni
00:10:01 <elliott> education = school
00:10:07 <elliott> = budget of approx. £0
00:10:12 <Vorpal> (and they are only there because other computers are non-legacy)
00:10:25 <Vorpal> (and we need parport programmers for some stuff)
00:10:28 <Vorpal> (like FPGAs)
00:10:31 <elliott> MIT still use Athena :P
00:10:42 <Vorpal> elliott, yeah but that is software. There is no excuse
00:10:48 <Phantom_Hoover__> elliott, FUN FACT: as far as I can tell, the Edinburgh Council computers all have BT branding as their screensavers.
00:10:59 <Vorpal> Phantom_Hoover__, BT?
00:11:00 <elliott> Phantom_Hoover__: wat.
00:11:02 <Phantom_Hoover__> And they refer to their "customers", which annoys me intensely.
00:11:02 <elliott> Vorpal: British Telecom.
00:11:08 <Vorpal> huh
00:11:10 <Vorpal> Phantom_Hoover__, WAT
00:11:11 <Phantom_Hoover__> YOU ARE A COUNCIL. NOT A BUSINESS.
00:11:13 <elliott> Heh, customers of the government.
00:11:20 <Phantom_Hoover__> LIVE WITH IT.
00:11:25 <elliott> Isn't it more like the government is *our* customer?
00:11:28 <elliott> Sort of.
00:11:36 <elliott> Well, really, the government is our contractor.

00:11:42 <elliott> We just seem to forget that every now and then.
00:11:44 <elliott> infanticide: GAK!
00:11:52 <infanticide> :)
00:11:56 <Phantom_Hoover__> It's more like "commercial metaphors can only lead to naïvety".
00:12:19 <elliott> Phantom_Hoover__: Sure.
00:12:29 <elliott> Phantom_Hoover__: But the government are definitely supposed to work for us. :p
00:12:34 <Vorpal> elliott, anyway, why athena?
00:12:41 <Vorpal> elliott, I mean.... there is no excuse to use that
00:12:51 <elliott> Vorpal: Because they invented it, and they have a LOT of machines with it.
00:12:58 <elliott> Vorpal: Hey, it runs gnome now. :p
00:13:03 <elliott> (And is based on Ubuntu, now, I think)
00:13:05 <Sgeo_> "og:url - The canonical, permanent URL of the page representing the entity. When you use Open Graph tags, the Like button posts a link to the og:url instead of the URL in the Like button code."
00:13:07 <Sgeo_> WTF
00:13:15 <elliott> Sgeo_: What?
00:13:22 <Sgeo_> That doesn't sound the least bit abusable
00:13:30 <Sgeo_> http://developers.facebook.com/docs/reference/plugins/like
00:13:32 <Vorpal> elliott, wait, a second, isn't athena just a GUI toolkit?
00:13:39 <elliott> Sgeo_: what
00:13:41 <elliott> Vorpal: no
00:13:48 <Vorpal> elliott, oh
00:13:57 <elliott> Vorpal: Athena is just what some people call Xaw, because Project Athena at MIT (involving DEC and IBM) created it
00:14:11 <elliott> Vorpal: Athena created X11, Kerberos and Zephyr.

00:14:28 <Vorpal> elliott, ah
00:14:29 -!- Zuu has quit (Client Quit).
00:14:48 <elliott> Vorpal: tl;dr: if MIT wants to have a bunch of semi-thin clients, they buy a bunch of expensive workstations, put Unix on them, invent X11 and Kerberos, connect them to a server, and call them thin clients.
00:14:53 <elliott> "Students would have access to (for the time) high performance graphical workstations, capable of 1 million instructions per second and having 1 megabyte of RAM and a 1 megapixel display." <-- THIN CLIENT
00:15:03 -!- Zuu has joined.
00:15:59 <Vorpal> elliott, well, if you need to do advanced computation then a lot of local resources might be good
00:16:07 <elliott> Vorpal: They're used to run Emacs :P
00:16:29 <Vorpal> elliott, see!
00:16:36 <elliott> ha
00:16:44 <elliott> eight megabytes and constantly swapping, not one!
00:16:49 <elliott> (okay, so they've been upgraded since then)
00:16:54 <elliott> Vorpal: http://blog.spang.cc/images/clean-athena.png Athena as of a few years ago.
00:17:03 <elliott> Vorpal: I understand it has been upgraded to be Ubuntu-based since then and probably the visuals too.
00:17:06 <pikhq> elliott: Well, when they started getting high-quality workstations was much more expensive than getting high-quality X terminals and UNIX systems.
00:17:11 <elliott> Vorpal: (That's GNOME 2.8. *In 2008.*)
00:17:25 <elliott> pikhq: X terminals didn't exist because X11 didn't exist.
00:17:31 <Vorpal> <elliott> Vorpal: http://blog.spang.cc/images/clean-athena.png Athena as of a few years ago. <-- still decent
00:17:35 <elliott> pikhq: They bought high-end workstations: 1 MIPS, 1 MB RAM, 1 megapixel display.
00:17:36 <Vorpal> compared to the original
00:17:39 <pikhq> elliott: ...
00:17:40 <elliott> Vorpal: 2.8!!!
00:17:44 <pikhq> elliott: Dear God.
00:17:46 <Vorpal> elliott, what version is gnome now. 2.16?
00:17:47 <pikhq> elliott: The overkill.
00:17:47 <Vorpal> I forgot
00:17:48 <elliott> pikhq: They /invented X/ to run on these.
00:17:50 <elliott> Vorpal: 2.32.
00:18:05 <elliott> Vorpal: 2.8 came out in 2004.
00:18:06 <pikhq> elliott: Okay, Athena would have made sense if X terminals were easily available.
00:18:11 <pikhq> elliott: But holy God that's nuts.
00:18:15 <elliott> pikhq: *AWESOME
00:18:16 <elliott> pikhq: Not nuts!
00:18:23 <Vorpal> pikhq, awesome for the students there
00:18:26 <pikhq> elliott: Okay, yes, I was actually looking for "crazy awesome".
00:18:28 <elliott> pikhq: Anyway, they all have their own copy of GNOME I think.
00:18:33 <elliott> Just /some/ apps are on a server.
00:18:40 <elliott> I think Emacs is, for instance.
00:18:42 <elliott> Maybe.
00:18:44 <Vorpal> elliott, except those at the AI lab. They had lisp machines
00:18:47 <elliott> Dunno about Firefox.
00:18:57 <Vorpal> (at some point at least)
00:19:03 <elliott> Vorpal: I'm pretty sure anyone could go down to the AI Lab :P
00:19:05 <pikhq> Vorpal: Lisp machines were falling out of vogue by the time Athena came into play.
00:19:11 <Vorpal> pikhq, ah
00:19:25 <pikhq> Though MIT almost certainly still had plenty at the AI lab.
00:19:29 <elliott> Athena started in 1983.
00:19:33 <elliott> So not "really".
00:19:41 <elliott> But yeah, it didn't take long for them to decline.
00:19:57 <elliott> Were they Symbolics, though? I doubt it.
00:20:02 <elliott> Since Symbolics grew out of the AI Lab.
00:20:20 <pikhq> Probably the AI Lab-built machines.
00:21:02 -!- Phantom_Hoover__ has quit (Remote host closed the connection).
00:21:50 <pikhq> It amazes me that X actually has support code for widget libraries.

00:22:08 <pikhq> Even though it was last used over a decade ago.
00:23:38 <elliott> widget libraries?
00:23:42 <elliott> presumably not gtk etc
00:24:32 <pikhq> Xaw and Motif.
00:24:48 <pikhq> They called out to Xt.
00:25:06 -!- cheater99 has quit (Read error: Connection reset by peer).
00:25:10 <Vorpal> night →
00:25:28 <elliott> pikhq: People still use Xaw. And Motif.
00:25:40 <Sgeo_> If Vorpal moves left, will time move backwards back into day?
00:25:51 <elliott> DEEP.
00:28:06 <elliott> pikhq: I NEED LANGUAGE SUGGESTIONS
00:29:28 <Sgeo_> elliott, Falcon Factor Haskell C C++ Java Newspeak Smalltalk Ur Python BancSTAR Brainfuck
00:29:34 <Sgeo_> ^^in no particular order
00:29:37 <elliott> Fail at interpreting my statement.
00:30:59 <elliott> pikhq: What would JESUS put in a language???
00:31:44 <elliott> coppro:
00:31:45 <elliott> elliott@dinky:~$ clang -fblocks bar.c -o bar
00:31:45 <elliott> /tmp/cc-FT8NmW.o:(.rodata+0x20): undefined reference to `_NSConcreteGlobalBlock'
00:31:47 <elliott> coppro: :(
00:32:40 <elliott> coppro: You never told me blocks don't work as regular function pointers :|
00:32:50 <pikhq> elliott: Jesus would put salvation into a language, and everyone else would turn it into C++.
00:32:52 <Sgeo_> elliott, something that prevents debuggers and statements used in a debugging context from working properly. You need faith that the program will work properly.
00:34:36 <elliott> "Clang doesn't yet provide an easy way to use blocks on platforms that don't have built-in operating system support (e.g., SnowLeopard)."
00:34:40 <elliott> pikhq: Can I see your copying code?
00:35:03 <pikhq> elliott: That line is bullshit.
00:35:13 <pikhq> elliott: http://compiler-rt.llvm.org/ You just need that library installed.
00:35:20 <elliott> pikhq: Right. Apparently it's not so mature though.
00:35:27 <elliott> (They linked to that in the same comment.)
00:36:13 <elliott> pikhq: But srsly, you can't use blocks as function pointers.
00:36:15 <elliott> i.e. useless to me
00:36:19 <elliott> No?
00:36:35 <pikhq> http://sprunge.us/eFJC There's a self-contained example.
00:36:53 <elliott> <elliott> pikhq: But srsly, you can't use blocks as function pointers.
00:36:54 <elliott> Is this true?
00:37:01 <pikhq> Hmm. Yeah, it is.
00:37:26 <elliott> <pikhq> http://sprunge.us/eFJC There's a self-contained example.
00:37:31 <elliott> Any way to avoid being explicit with the closure?
00:37:38 <elliott> That's kind of a pain as a compiler-writer.
00:37:38 <pikhq> No.
00:38:05 <elliott> What's the name of the compiler-rt lib?
00:38:20 <elliott> There's librt but it's not that.
00:40:31 <elliott> pikhq: Are you suuure I can't avoid explicit closing?
00:40:59 -!- cheater99 has joined.
00:41:31 <pikhq> elliott: If you can avoid ever popping the function off the stack, you can use GCC's automatic closing.
00:41:40 -!- zzo38 has joined.
00:41:56 <elliott> pikhq: Hmm. Well, can I just list all the variables mentioned in the function body and that would be sufficient?
00:42:12 <elliott> pikhq: Also: How do you avoid invoking gcc's automatic closing in that code?
00:42:17 <zzo38> Should C have a allocprintf command?
00:42:32 <elliott> zzo38: To do what?
00:42:43 <zzo38> elliott: What do *you* think?
00:42:50 <elliott> zzo38: I have no idea.
00:43:00 <pikhq> elliott: I do not ever use any variable from the enclosing scope.
00:43:07 <Sgeo_> zzo38, how difficult would it be to port MegaZeux to Flash?
00:43:12 <zzo38> elliott: You cannot guess what I meant?
00:43:14 <elliott> pikhq: Heh.
00:43:16 <elliott> zzo38: No.
00:43:29 -!- cheater99 has quit (Read error: Connection reset by peer).
00:43:29 <zzo38> Sgeo_: I don't know. But I suggest you don't port MegaZeux to Flash.
00:43:56 <Sgeo_> :(
00:43:57 <zzo38> Can you compile C programs with SDL into Flash? If so, then it is easy. But I don't think you can do that.
00:44:08 <elliott> Well, you can compile C to Flash.
00:44:12 <elliott> A guy ported Doom to Flash that way.
00:45:07 <zzo38> Sgeo_: Why do you want it in Flash anyways? It is much better native (it will both be faster and will not require a Flash player).
00:45:34 <Sgeo_> So more people will play MegaZeux games!
00:46:11 <zzo38> Sgeo_: MegaZeux will compile on most operating systems, including Nintendo DS.
00:47:02 <Sgeo_> It's impossible to get lazy people to go through that effort to play what feels like a flash game
00:47:04 <zzo38> (But if you can find a way to compile C programs with SDL into Flash, you can try compiling mzxrun only into Flash, although I still don't like it.)
00:51:03 <zzo38> Sgeo_: Mainstream MegaZeux executables are available for most common operating systems. For my version, executable is available only on Windows to download, but it works on other operating systems too. If anyone wants to contribute executables of my MegaZeux in other operating system, I might post a link to those ones too.
00:51:53 <zzo38> elliott: What I meant by "allocprintf" is one that is like
00:52:15 <zzo38> "sprintf" but it automatically allocates it too.
00:52:43 <elliott> zzo38: allocsprintf would be a better name. GLib has that, by the way.
00:53:10 <zzo38> elliott: I didn't know that before.
00:53:17 <elliott> zzo38: http://library.gnome.org/devel/glib/stable/glib-String-Utility-Functions.html#g-strdup-printf
00:53:58 <zzo38> But that's for GNOME isn't it?
00:54:24 <elliott> zzo38: No.
00:54:29 <elliott> zzo38: GLib is portable.
00:54:45 <elliott> zzo38: And works in programs with any type of interface; it does not depend on any interface library.
00:54:59 <zzo38> Well, either way, I am writing the program without such functions because it doesn't have it, I was just mentioning something that I might find useful. It is not absolutely necessary.
00:55:51 <pikhq> zzo38: Glib just happens to be heavily used by Gnome; it's a fairly generic "throw everything in that should've been part of the C library" sort of thing, though.
00:56:09 <pikhq> Well, it also has that revolting object system.
00:57:12 <elliott> Yes, but you don't have to link that in. :p
00:58:25 <zzo38> Sgeo_: Have you played my MegaZeux game yet, though? (It is recommended you download my copy of both the world file and the MegaZeux program, but you don't have to (for Part I).)
00:58:59 <Sgeo_> pikhq, what's horrible about it?
00:59:16 <Sgeo_> I mean, besides trying to use it in its native language?
00:59:31 -!- cheater99 has joined.
00:59:57 <zzo38> What I know is that when I need a object system in a C program, I will write one that is suited for that specific program that I am writing.
01:00:24 <Sgeo_> zzo38, that's because you're zzo38 >.>
01:01:28 <elliott> GLib is pretty awful in reality :P
01:01:29 -!- cheater99 has quit (Read error: Connection reset by peer).
01:01:47 <Sgeo_> elliott, to use from C, or even from a language like Vala/Genie?
01:01:58 <elliott> GLib is just awful full stop.
01:02:03 <elliott> But it has some useful functions.
01:02:48 <zzo38> I have written more of TeXnicard already. Including pattern matching.
01:03:48 <elliott> pikhq: srsly though, I don't think Debian has a compiler-rt package.
01:04:02 <zzo38> elliott: What is a compiler-rt package?
01:04:13 <elliott> A thing for LLVM.
01:05:38 <elliott> aha
01:05:42 <elliott> libblocksruntime-dev
01:05:45 <elliott> split out by stupid debian
01:06:04 <elliott> pikhq: Are you sure there's no way to cast a block to a function pointer?
01:07:26 <zzo38> I have a idea of esolang that nearly everything must be done by solving a halting problem. What is the minimum number of other things needed?
01:10:17 <pikhq> None that I know of.
01:12:58 <elliott> pikhq: Bleh, I can't figure this out at all...

02:46:04 <Sgeo_> Chrome's been acting up again lately
02:46:15 <Sgeo_> I'm almost tempted to switch back to Opera
02:46:50 <Mathnerd314> elliott: it has message passing, and pattern matching, and multiple dispatch, and... the rest is part of the front-end I have to implement
02:46:58 <elliott> Mathnerd314: strongly typed?
02:47:09 <Mathnerd314> dynamically typed
02:47:35 -!- cheater99 has joined.
02:47:36 <elliott> Mathnerd314: worthless
02:47:42 <elliott> Mathnerd314: is it purely functional or impure?
02:48:05 <Mathnerd314> the type system is part of the front-end
02:48:10 <Mathnerd314> purely functional
02:48:21 <elliott> Mathnerd314: hmm. maybe not entirely worthless then
02:48:34 <elliott> Mathnerd314: message passing/multiple dispatch have a lot of overlap -- why not just pick one?
02:49:09 <Mathnerd314> it has both; they're implemented in the same lines of code
02:49:09 -!- cheater99 has quit (Read error: Connection reset by peer).
02:49:19 <elliott> Mathnerd314: that's not a reason
02:49:38 <elliott> careful, thought-out design taking into account what to exclude as well as what to include > "it didn't take many lines of code so I threw it in"
02:49:39 <Mathnerd314> umm... because I like power, and this is more powerful?
02:49:55 <elliott> so far every time you've used the word power it's been to justify a bad idea ... but very well.
02:50:29 <Mathnerd314> actually, it doesn't *really* have pattern-matching
02:50:37 <elliott> i didn't even object to pattern matching
02:51:25 <Mathnerd314> yeah, that's why it doesn't have it. because it has no data structures.
02:51:28 <Sgeo_> Is it "more power" to drop the strong typing from Haskell? More power in that case -> suck
02:51:50 <Mathnerd314> Sgeo_: it has no type system yet. OK?
02:52:10 <Sgeo_> Mathnerd314, I was commenting on the idea of "power", not your language speciically
02:52:10 <elliott> Mathnerd314: if it has no data structures, what do you send messages to?
02:52:14 <Sgeo_> specifically
02:52:14 <elliott> also: how do you decide what dispatch to use?
02:52:45 <Mathnerd314> elliott: environments
02:52:50 <elliott> Mathnerd314: go on.
02:53:26 <Mathnerd314> an environment takes some code and evaluates it. I have an environment which can construct other environments
02:54:29 <Mathnerd314> and which dispatches to them
02:54:30 <elliott> i still think that having both message passing /and/ multiple dispatch is a design flaw. or at least an indicator of badly-thought-out design.

04:22:49 <Ilari> Hmm... Last 30 days allocation lists for APNIC, 16x/14, 6x/13, 4x/12. That's about 11Mi addresses (plus then there are the <250k allocations...)
04:23:39 <Sgeo_> http://www.amazon.com/Wishing-Well-Making-Your-Every/dp/078686561X . This book. This horrible, evil book
04:25:06 <Ilari> Also intersting to look at raw allocation counts for 250k+ allocations: 5 for RIPE, 1 for ARIN, 1 for LACNIC, 2 for AfriNIC and 26(!) for APNIC.
04:26:33 <Ilari> Runner-up in large allocations: RIPE with 5.25Mi. That's not even half of APNIC.
04:29:42 <Sgeo_> As a kid, I had a bad reaction to the woowoo in that book
04:30:18 <Sgeo_> Some people find comfort in that sort of BS. I found abject fear that haunts me to this day
04:32:36 <pikhq> 5 forms of the final boss remaining.
04:33:02 <Ilari> Allocations this month: ARIN: 1 693 696. AfriNIC: 384 000. LACNIC: 1 095 936, RIPE: 3 953 920, APNIC: 12 063 232. Yes, APNIC allocated way more addresses than all the other RIRs COMBINED.

04:35:54 <Sgeo_> elliott, are you unaware of how easily kids can be affected by this sort of stuff?

04:39:18 <elliott> pikhq: ur lame
04:39:22 <pikhq> And the final boss is still a pain with the infinity-plus-one.
04:39:30 <Sgeo_> elliott, did you just call Ur lame/
04:39:33 <pikhq> You see, it has 12 forms. You have to kill each one.
04:39:36 <elliott> Sgeo_: shut up
04:40:07 <pikhq> Each one is a difficult boss in and of itself.
04:40:59 <elliott> pikhq: lawl
04:41:25 <pikhq> Except I one-shot each one.
04:41:37 <pikhq> I just need to have enough full-SP-heal items to get through.
04:41:41 <pikhq> Which I do.
04:41:58 <Sgeo_> I find no fear in the idea of an afterlife, only comfort. In the idea of being able to control reality with your mind, I find the most horrible painful fear.
04:42:07 <pikhq> FINISHED.
04:45:04 <pikhq> SATAN DEFEATS ALL
04:45:46 <elliott> pikhq: Good ending.
04:46:08 <pikhq> elliott: Yes, I used Satan to defeat the end of the world.
04:46:12 <elliott> Sgeo_: You can do that, it happens by sending a few signals down to effectors which effect changes in the world around them.
04:46:42 <Sgeo_> pikhq, it would be better if it were an unwilling Anti-Christ
04:47:19 <pikhq> elliott: I could've used Odin instead; would that have made you feel better?
04:47:57 <elliott> pikhq: No.
04:48:04 <pikhq> elliott: Messiah?
04:48:05 <elliott> Sgeo_: Why aren't you in abject terror?
04:48:08 <elliott> pikhq: NO. SATAN
04:48:16 <pikhq> Okay, then. Satan it was.
04:48:24 * pikhq rocks the devil horns
04:48:34 <Sgeo_> Because the only real way for my mind to affect reality is limited
04:48:58 <Sgeo_> My OCDish thoughts of people dying aren't going to kill them
04:49:02 <elliott> Not very limited if you're an atom.
04:49:05 <elliott> Also, what.
04:49:09 <elliott> What the fuck has OCD got to do with that what
04:49:33 <Sgeo_> I thought OCD has to do with more severe unwanted thoughts than normal
04:49:48 <elliott> I don't think you have any idea what OCD is, shut up
04:50:12 <Sgeo_> Well, I'm pretty sure there is a name for what I just described. I don't think I have it, but
04:50:44 <elliott> Sgeo_: Um, thinking things you don't want to?
04:50:48 <elliott> Here's a name for that: existing.
04:50:57 <Sgeo_> elliott, but more severely and painfully than normal
04:50:59 <pikhq> Sgeo_: OCD implies obsessive compulsions. And that it's a disorder.
04:51:03 <elliott> Sgeo_: Umm... painfully?
04:51:08 <elliott> Sgeo_: Just checking -- are we talking physical pain here
04:51:51 <Sgeo_> elliott, I don't know, ask the person I was talking to
04:51:59 <Sgeo_> IRL
04:52:33 -!- cheater99 has joined.
04:54:38 <Sgeo_> Well, you know what sort of thoughts I'm talking about, you said they were a part of existing
04:54:55 <elliott> Let's call it QRD. For the sake of argument.
04:55:04 <elliott> If your thoughts did not involve the mentioned pain, how can you even say they are QRDly?
04:55:36 <Sgeo_> Because the other attribute of being unwanted is still there
04:55:36 -!- cheater99 has quit (Read error: Connection reset by peer).
05:01:10 <elliott> Sgeo_: So let's say that a giraffe is an animal with spots and a long neck.
05:01:22 <elliott> Sgeo_: Therefore jaguars are giraffey.
05:01:46 <Sgeo_> Ok, maybe I shouldn't have said OCDish, or maybe my understanding is wrong
05:01:49 <Sgeo_> Or inaccurate
05:07:36 <elliott> whoa myndzi is pronounced mind-zy

11:50:24 -!- cheater99 has quit (Read error: Connection reset by peer).
11:50:43 <Vorpal> the only problem with that analogy is that C is way less modular
11:51:21 <Vorpal> (so, it is like lego, except when it comes to one of the key defining properties of lego)
11:52:03 <Phantom_Hoover> cpressey was on?

11:55:20 <Phantom_Hoover> 23:25:27 <zzo38> Welcome to the esoteric programming channel!

12:07:53 -!- cheater99 has joined.
12:13:02 <Ilari> Okay, why is stunnel trying to create localhost-only AF_INET port and then trying to connect to it?
12:16:47 <Vorpal> Ilari, what is stunnel for now again?
12:17:14 <Ilari> Similar to inetd, but listens for TLS connections instead of plaintext.
12:17:40 <Vorpal> hm
12:17:49 <Ilari> "trying" because it doesn't work and as result, stuff keeps failing...
12:17:55 <Vorpal> Ilari, must be config issues
12:17:57 <Vorpal> or bugs
12:18:14 <Vorpal> (I think that exhausted all possibilities :P)
12:22:01 <Vorpal> Ilari, has it worked before?
12:22:41 <Ilari> Yes it has.
12:23:05 <Vorpal> Ilari, so what did you change (if anything?)
12:23:38 <Ilari> Hmm... Maybe it has always done that localhost connect thingy...
12:23:56 <Vorpal> Ilari, well, presumably it hasn't always been failing
12:24:44 <Vorpal> hm, is lo up when you get to userspace on linux?
12:24:52 <Vorpal> or does some early init script start lo
12:26:02 <Vorpal> ah, /etc/rc.sysinit has /sbin/ifconfig lo up
12:26:24 <Vorpal> right after udev basically
12:27:07 <Ilari> Ah, apparently strunnel is configured to use AF_INET instead of AF_UNIX for temporary internal sockets. Bleh.
12:27:28 <Vorpal> Ilari, the whole "temporary internal sockets" thing sounds weird
12:27:42 <Vorpal> Ilari, however, connecting over lo should work on every sane system
12:28:10 <Vorpal> if someone has a crazy enough firewall that it doesn't work, then it is really their own issue
12:29:47 <Vorpal> $ unbound-control dump_cache | wc -l

12:34:53 <Vorpal> hm
12:35:07 <Vorpal> I think the parsing fails somewhat
12:35:25 <Vorpal> ah + there gives more reasonable results...
12:35:53 -!- augur has joined.
12:39:51 <Ilari> Hah... stunnel segfaulted.
12:40:32 <Vorpal> Ilari, why is it an issue that it uses AF_INET and lo?

12:43:11 <Vorpal> hah
12:43:23 <Vorpal> and NS dominates.
12:43:25 <Ilari> Firewall rules.
12:43:32 <Vorpal> Ilari, they restrict lo?
12:43:38 <Vorpal> Ilari, if so they are utterly bonkers
12:44:19 <Vorpal> Ilari, you should setup a data diode or whatever it is called on lo. Just firewall is too insecure!
12:45:50 <Ilari> Stunnel crashes even if client doesn't try to send client certificate.
12:48:09 <Vorpal> Ilari, but why are you firewalling lo to this insane degree?
12:49:19 <Ilari> There's stunnel3 compat binary as well. Crashes just as good when connecting.
12:49:43 <Vorpal> Ilari, yeah, but uh, why are you firewalling lo to this degree. That is the real wtf
12:50:32 -!- cheater99 has joined.

12:54:21 <Ilari> -> Stunnel sucks...
12:54:36 <Vorpal> Ilari, just fix the insane firewall rule
12:54:51 <Vorpal> Ilari, really, what are the rules for lo?
12:55:23 <Ilari> Same as global, plus few extra ports allowed.
12:55:34 <Vorpal> Ilari, why are you surprised stuff breaks then
12:56:08 <Ilari> I expect software to use AF_UNIX for local stuff internally, not AF_INET to loopback.
12:56:18 <Vorpal> Ilari, the usual way is to check for invalid state (and on ipv6 for rt type 0), then the rule after that/those is generally "if loopback, allow"
12:56:30 <Vorpal> Ilari, you expect too much
12:56:49 <Vorpal> Ilari, besides, what does it add to security? I doubt anything.
12:57:01 <Deewiant> Windows-portable software will likely not use AF_UNIX for anything.
12:57:08 <Vorpal> Deewiant, that too
12:57:26 <Ilari> I actually have built version of stunnel that uses AF_UNIX as it should. Except that that crashes if client tries to connect...
12:57:36 <Vorpal> Ilari, probably because few people use it
12:58:10 <Vorpal> Ilari, also, shouldn't you use something like selinux or similar to limit what unix sockets each program can use
12:58:14 -!- oerjan has joined.
12:58:18 <Ilari> It crashes inside SSL client certificate routines, which AFAIK come before it tries to use internal sockets...
12:58:18 <Vorpal> oerjan, hi
12:58:25 <oerjan> g'day
12:58:26 <Vorpal> Ilari, hm.
12:58:40 <Vorpal> Ilari, I suggest you go back to the previous working setup and try again
12:59:04 <oerjan> damn rsi acting up again :(
12:59:11 <Vorpal> oerjan, rsi?
12:59:33 <Vorpal> oerjan, (as in, which meaning of rsi)
12:59:45 <oerjan> the one which it's painful to type out
12:59:51 * oerjan ducks
13:00:18 <Vorpal> oerjan, ah that would be "Register Storage Immediate"
13:00:18 * oerjan then whimpers
13:00:27 <Ilari> It crashes instantly after receiving the client certificate...
13:00:38 <Vorpal> Ilari, even on the previous working setup?
13:00:41 * oerjan swats Vorpal -----###
13:00:54 <Vorpal> oerjan, use speech to text or something
13:01:00 <Vorpal> oerjan, it would be a good laugh
13:01:28 <oerjan> this laptop doesn't actually have a microphone. also i hate unnecessary sounds.
13:03:07 <Ilari> Okay, 3.26 works (including invoking the program) if I don't send a client ceritificate. 4.34 crashes even if I don't send it.
13:03:28 <Vorpal> Ilari, is this with or without insane firewall setup?
13:03:43 <Vorpal> Ilari, for purposes of debugging you should test if it affects anything
13:03:52 <Vorpal> bbl
13:08:11 <Vorpal> oerjan, no external mic?
13:09:50 <oerjan> no
13:09:52 <Vorpal> oerjan, also, I never imagined you as one using a laptop.
13:10:02 <Vorpal> oerjan, I mean, a vt100 sounds more your style
13:10:08 <oerjan> :D
13:10:08 <Vorpal> or maybe a workstation
13:10:19 <Vorpal> that would work too
13:10:26 <oerjan> sure, when i was at the university...
13:10:41 <Vorpal> oerjan, yeah, but laptop just doesn't suite you!
13:10:53 <Vorpal> oerjan, at least use a desktop
13:11:01 <Vorpal> even I use a desktop at home
13:12:58 <Vorpal> oerjan, besides laptops are not comfortable for long time use (say, more than a 4-5 hours / day)
13:13:10 <oerjan> you don't say. *ouch*
13:13:53 <Vorpal> oerjan, the touchpad is useless. And the trackpoint finger gets sore after a few hours
13:14:14 <Vorpal> mouse ends up at wrong height often.
13:14:24 <oerjan> i don't mind the touchpad, there is no trackpoint
13:14:24 <Vorpal> and of course the monitor is in the wrong place
13:15:26 <Vorpal> oerjan, and the travel distance on laptops sucks
13:16:45 <Vorpal> oerjan, at least I hope it has full sized keys
13:16:45 <oerjan> well i don't actually bring it anywhere anyhow
13:16:54 <oerjan> yes
13:17:28 <Vorpal> oerjan, anyway, they are inferior to a proper mechanical keyboard
13:18:18 <Ilari> Ah, found out why stunnel crashes: OpenSSL library/header mismatch.

13:39:49 <Vorpal> what was that site to find shortest path on wikipedia?
13:39:56 <Vorpal> between two articles
13:40:31 <oerjan> Gregor had a game based on it
13:40:41 <Vorpal> oerjan, I remember some automated tool for it
13:40:46 <oerjan> ah
13:40:53 <fizzie> There are several.
13:41:13 <Vorpal> fizzie, right, happen to know where to find one?
13:41:15 <fizzie> Quick googling found me http://thewikigame.com/ but not the one that had the psychedelic color-flashery and link-dropping feature.
13:41:35 <Vorpal> fizzie, the one I remember was just a pain white page
13:41:37 <fizzie> (That one has a few game modes though.)
13:41:38 <Vorpal> fizzie, like, no css
13:42:00 <Vorpal> fizzie, and I don't want it as a game, I want it as a tool that tells me the shortest path.
13:42:09 <fizzie> Oh, that.
13:42:29 <Vorpal> fizzie, yes, I googled but can't find it
13:42:38 <fizzie> http://www.netsoc.tcd.ie/~mu/wiki/ ?
13:42:42 <fizzie> (It's linked from Wikipedia.)
13:42:45 <Vorpal> heh
13:43:10 <Vorpal> fizzie, hm, I guess that works. Not the one I thought of. But any tool that does the job is okay

13:46:02 <Vorpal> fizzie, it could be http://www.netsoc.tcd.ie/~mu/wiki/ if they redesigned that page. The result page looks similar to what I remember
13:46:21 <fizzie> I guess they could've just prettified it up a bit.
13:47:56 <Vorpal> fizzie, anyone know what the longest path is (excluding those of infinite length due to lack of any links between)
13:49:10 <fizzie> "Several people were asking about what's known as the "diameter" of Wikipedia, that is, the distance between the two articles furthest apart (the longest shortest path if that makes any sense to you). This was in fact the original goal of the project but it turned out not to be very interesting. Wikipedia has giant "tails", almost linear linked lists of articles that stretch out for 70 links."
13:49:16 <fizzie> That's on that six-degrees page.
13:49:26 <Vorpal> ah
13:49:40 <fizzie> "Even when I special-cased out that string of 70 boring articles, a new one appeared (I think it was linked pages about administrations of Myanmar or something)."
13:49:45 <ineiros> Hello.
13:49:49 <Vorpal> fizzie, heh
13:49:50 <Vorpal> ineiros, hi
13:50:04 <fizzie> But the center of wikipedia (in March 2008) was "2007".
13:51:09 <oerjan> didn't they change policy to include less year links in articles?
13:51:26 <oerjan> i think i saw some being edited away at one time
13:53:05 <oerjan> don't recall if it was before or after 2008 though
13:53:21 <Vorpal> fizzie, hm, I wonder if wikipedia has an Eulerian path...
13:53:27 <Vorpal> probably not
13:53:40 -!- yiyus has quit (Read error: Operation timed out).
13:54:22 <Vorpal> a Hamiltonian path would be interesting as well
13:54:52 <fizzie> There are pages with no incoming links and multiple outgoing links (like some disambig pages), so no.
13:55:00 <oerjan> both of those only need three articles with either no paths out or no ... right
13:55:42 <Vorpal> fizzie, what about the set of all pages that can be reached from the centre.
13:55:55 <Vorpal> still, dead ends I guess
13:55:56 <Vorpal> hm
13:56:06 <oerjan> you need paths both ways
13:56:10 <Vorpal> oerjan, yeah
13:56:15 <fizzie> Yes; I don't know about the strongly-connected component, though.
13:56:27 <Vorpal> so, we need to carefully tweak the pages so that such a graph is possible
13:56:36 <oerjan> even then it can easily fail i think
13:56:43 <fizzie> Yes, probably.
13:56:47 <Vorpal> hm
13:56:50 <fizzie> "A directed graph is Eulerian if it is strongly connected and every vertex has equal in degree and out degree."
13:56:58 <fizzie> That sounds like it's unlikely to hold.
13:57:04 <oerjan> for eulerian path you cannot have too many with an odd number of in/out neighbors
13:57:23 <Vorpal> fizzie, so Hamiltonian path might be more feasible
13:57:26 <oerjan> oh wait _directed_ too
13:57:39 <fizzie> Well, the links are quite naturally directed.

14:08:36 <Vorpal> and empty inventory
14:08:41 <fizzie> Well, it was also beta 1.1_02 and no hMod.
14:08:45 <fizzie> So I assume it's for testing.
14:08:48 <Vorpal> ah
14:09:01 <Vorpal> well, not much point in playing on it
14:25:33 <Phantom_Hoover_> How do I get Debian to let me install Sid packages if necessary, but use the Squeeze packages by default?
14:27:50 <fizzie> Add both to sources.list, then write an APT preferences file to prefer squeeze, but include sid with a lower priority.
14:27:55 <fizzie> Cf. http://jaqque.sbih.org/kplug/apt-pinning.html
14:30:48 <Phantom_Hoover_> fizzie, not working!
14:31:15 <fizzie> Well, it has worked for me for a mixed-distribution Debian. How is it not working?
14:31:46 <Phantom_Hoover_> apt-get upgrade still lists insanely huge numbers of packages to upgrade!
14:32:15 <fizzie> Oh, http://wiki.debian.org/AptPreferences is the official version of above.
14:33:43 <fizzie> What about "apt-get --dry-run -t testing upgrade", does that want to upgrade the world too?
14:34:46 <fizzie> It should be no different than using the preferences-file driven pinning, though.
14:35:22 <Phantom_Hoover_> fizzie, assuming I can s/testing/squeeze/, since that's what's on all of my apt lines.
14:35:45 <fizzie> Well, you could try both. I think they should be usable interchangeably there.

15:02:13 <elliott> Phantom_Hoover_: A creeper and a skeleton are currently molesting me from the game over screen.
15:02:19 <elliott> Oh, now a zombie too.
15:02:38 <elliott> Phantom_Hoover_: So I should have rounded up a few enemies if anyone else wants to go on :P

15:08:21 <fizzie> I don't know; I haven't heard anything from ineiros except the "hello" on-channel.

15:20:21 <ineiros> Hello.
15:21:20 <ineiros> elliott: The placed spawners apparently only spawn pigs. I would like to have the capability to edit them, though. But hey, free bacon.
15:22:20 <ineiros> I thought to have something else there for a few days until the hMod is stable again.
15:23:09 <ineiros> Also, if someone wants to have maps at some point, you should point me to a system that can handle the current mess.
15:25:22 <elliott> ineiros: You use cartomograph, right?
15:25:27 <elliott> Also: plz keep it like this, it's awesome.

15:30:51 <ineiros> elliott: No, pymap.
15:31:05 <fizzie> ineiros: Why didn't you just patch the region?
15:32:38 <ineiros> fizzie: Setting the extents manually caused an exception elsewhere in the code. Didn't have motivation to look further into the code.
15:33:18 <fizzie> Also, wasn't it pynemap instead of pymap?
15:33:41 <ineiros> fizzie: Yes, my bad.
15:34:14 <fizzie> I haven't tried the others; Cartographer 5's Linux port didn't have extents-setting features.
15:34:32 <fizzie> Someone has done a google-maps driven map already, though, http://www.triangularpixels.com/Junk/TectonicusTest/map.html
15:36:03 <fizzie> http://www.minecraftwiki.net/wiki/Programs_and_Editors#Mappers says of one that it's the "The fastest mapper available; capable of processing very large maps. Supports multiple modes including cave maps and resource highlighting." but it seems to be Windows-only, according to them little icons.
15:39:37 <fizzie> I still want to do that google maps / openlayers -based web-tile-mapper at some point, though I'd prefer if it had quasi-real-time player markers and such from a server plugin too.
15:46:10 <elliott> fizzie: The Google Maps ones take up many-the-gigs of storage space, I gather.
15:46:55 <fizzie> They could have a limited-size cache and on-the-fly generation.
15:47:59 <elliott> fizzie: That'll not slow the server down at all, nope.
15:48:01 <elliott> :p
15:48:45 <fizzie> Well, it could be done on some other box with the world rsync'd every now and then. Not sure how easy it is to add real-life geodata on top of gmaps. (Or openlayers.)
15:48:49 <elliott> "Minecraft is about to go up in price, so today is your last chance to buy it for €10. Obviously I recommend it.

16:30:51 <elliott> Or never.
16:31:01 <elliott> The maps would be cleaner. :p
16:31:08 <elliott> I'm even getting used to dying! A LOT!
16:34:55 <fizzie> elliott: Based on the hmod github commit-log, it's still seeing quite a lot of development, so I'd personally still wait a while. (Though of course for bleeding-edge testing...)
16:35:18 <elliott> fizzie: Isn't that the motto of the League of Notch Apologists? "YOU'RE the testers!"
16:38:43 <Vorpal> elliott, that is only because haven't built anything really complicated. Sure the stairs were massive, but they didn't actually take that long. Something like fizzie's house and bunker is a lot more work
16:39:06 <Vorpal> so yeah, we should go back to the proper map when we have a working hmod

18:12:30 <Vorpal> text adventure speed run. How would you measure it?

18:12:45 <pikhq> elliott: Not necessarily.

18:12:57 <Vorpal> elliott, ah
18:13:01 <pikhq> elliott: But the good ending would be PAINFUL.
18:13:08 <elliott> Vorpal: Take a look at this: http://www.the-spoiler.com/ADVENTURE/Infocom/trinity.1.html
18:13:30 <elliott> Including comments.
18:13:56 <pikhq> elliott: There's a 260 floor dungeon. It is only mandatory at the very end of the good ending.
18:15:02 <elliott> pikhq: Can you one-shot it? :P
18:15:17 <pikhq> I can one-shot everything!
18:15:32 <elliott> pikhq: Can you do the bad ending, then go back and do the good ending?
18:15:47 <elliott> If so: do that, just so you can say you did the ABSOLUTE MINIMUM REQUIRED TO COMPLETE IT the first time.
18:15:49 <pikhq> I can load from a savepoint, yes.
18:16:04 <elliott> Save right before the bad/good diverge point :P

18:42:36 -!- Sasha has joined.
18:43:20 <elliott> j-invariant: hmm i should implement computable dedekind cuts
18:43:24 <tswett> If it's pitch-black hole, mobs can spawn in it.
18:43:33 <j-invariant> not sure how you do arithmetic with them
18:43:35 <elliott> tswett: As I said, it's 1x1. So they'd have to spawn... on me.
18:43:41 <elliott> j-invariant: me neither ...
18:43:54 <elliott> tswett: Technically, they have .3 m above my head to cram into.
18:44:17 <elliott> Aaand the server went down.
18:44:23 <tswett> Hm. Perhaps you and them are both really narrow, or something. I don't know if they can spawn there or not.
18:44:39 <Vorpal> pikhq, if they are large, is it randomly generated or something (or at least generated + hand edited, actually making that many floors, if large, by hand sounds painful)
18:45:52 <tswett> You know, I would probably get some enjoyment out of a game that is just a randomly-generated world that you can explore.
18:45:59 <tswett> Do nothing else. Just explore.
18:51:42 <Vorpal> elliott, local game: larger overhang than mt hoover. Also it turns 90 degrees halfway out. And there is no scenery cut off to explain it (that game is all post-halloween)
18:52:04 <pikhq> Vorpal: It is mostly randomly-generated.
18:52:27 <Vorpal> pikhq, hm okay
18:52:37 <pikhq> Vorpal: And changes each time you go to a floor.
18:52:39 <Vorpal> pikhq, I guess it isn't very story-heavy then?
18:52:41 <Vorpal> pikhq, ha
18:53:02 <pikhq> Oh, it's very story-heavy. The design of the single dungeon is just irrelevant to the story.
18:53:22 <Vorpal> elliott, wow there are 2 more overhangs like it visible from under the middle one
18:53:36 <pikhq> And aside from the very end of the good ending, it's entirely optional.
18:53:38 <Vorpal> elliott, and a rather large floating island

18:54:00 <Vorpal> pikhq, is there just /one/ good ending?

19:00:48 <pikhq> elliott: Said boss is entirely beatable without leveling.
19:00:53 <elliott> pikhq: Sounds ... silly.
19:01:29 <pikhq> elliott: It's essentially scripted up until then.

19:02:32 <elliott> dunno if you know
19:03:25 <elliott> Aww, a zombie swimming, how cute.
19:03:28 <elliott> And a creeper.
19:03:34 <elliott> Wait, what? It's LIGHT now, why are you appaering now.
19:03:49 <elliott> Haha burn

19:07:44 -!- wareya_ has quit (Ping timeout: 264 seconds).
19:08:57 <j-invariant> elliott: any ideas about this proof
19:09:03 <j-invariant> http://i.imgur.com/n4gcr.png
19:09:27 <j-invariant> I have mn = id, nm = id, etc.. and I want to show that Ff = m Gf v
19:12:35 <elliott> fizzie: That lasted long.
19:12:43 <elliott> j-invariant: no idea :/
19:12:47 <fizzie> Yes, I foolishly tried out mcmap.
19:12:59 <elliott> j-invariant: eapply has me trying to prove things on ?7
19:13:04 <elliott> rather than getting me to specify ?7 first
19:13:08 <elliott> or is there a tactic for that too?
19:13:12 <j-invariant> elliott: yeah if that happens you are in trouble
19:13:16 <elliott> fizzie: can you please bring bacon? :{
19:13:32 <j-invariant> say you have category with identity compose and some axioms..
19:13:33 <elliott> j-invariant: hmm there's a command to declare a subgoal with a specified type right?
19:13:58 <j-invariant> then a good way is instead of eapply Build_Category. you can do apply (Build_Category <definition of identity> <definition of compose>). tehn you get goals left over for all the axioms
19:14:08 <j-invariant> that's how I get around the ? stuff
19:14:13 <fizzie> Strange stuff; mcmap goes into a 100% CPU utilization loop.
19:14:21 <j-invariant> but it can be difficult to write the definitions in situ
19:14:27 <elliott> fizzie: you sure do listen to my pleas :P
19:14:36 <fizzie> I don't have any bacon to bring.
19:14:45 <elliott> fizzie: there's a mob spawner at spawn.
19:14:47 <elliott> it makes lots of pigs
19:14:53 <elliott> punch => food
19:15:08 <fizzie> Well, as soon as I get mcmap to actually let me in.
19:15:17 <j-invariant> elliott: I'mk stating to think that teh theorem isn't true
19:15:23 <j-invariant> need more assumptions
19:17:34 <elliott> fff now I need to refer to Z's ^
19:17:35 <elliott> but it's Q's
19:17:40 <elliott> and i've forgotten how to override scope

19:30:28 <elliott> fizzie: Lagg.
19:30:38 <elliott> j-invariant: i don't know of one, way further than i've got
19:30:47 <fizzie> Lagg indeed.
19:31:00 <fizzie> I threw out three bacon, I don't know if they disapparated somewhere. Hope not.
19:31:19 <elliott> fizzie: They were in my inventory when I spawned falling into nothingness.
19:31:25 <fizzie> Okay.
19:31:41 <elliott> fizzie: You can stay at my house, FWIW. If you're staying on that is.
19:31:41 <fizzie> I'm not going to start actually playing there, though, I just wanted to check if mcmap worked.
19:31:55 <elliott> fizzie: See how boring you are?!

19:40:28 <elliott> grr
19:40:33 <elliott> how do you do that if p's ^ is in Z_scope
19:40:36 <elliott> but q's ^ is in positive_scope?
19:40:59 <j-invariant> something liek (q^3)%Z_scope
19:41:31 <elliott> oh yeah
19:41:40 <elliott> j-invariant: well no q is positive_scop

19:53:57 <elliott> well this looks fun.
19:55:00 <j-invariant> what's Is_true?
19:55:04 <elliott> j-invariant: from Bool
19:55:08 <elliott> it's just if x then True else False
19:55:16 <elliott> j-invariant: hmm i'd be better off using match rather than destructing with Qnum and Qden right?
19:55:16 <j-invariant> oh I see
19:55:29 <j-invariant> wait that means the theing is decidible
19:55:37 <j-invariant> well no because it's quantified
19:55:43 <elliott> j-invariant: right
19:55:48 <Vorpal> elliott, http://sporksirc.net/~anmaster/minecraft/screenshots/overhang/
19:55:52 <Vorpal> elliott, that beats mt hoover eh?
19:55:54 <j-invariant> if you destruct s it should simplify to the same thing
19:56:06 <elliott> gah, i've forgotten all the tactics
19:56:29 <j-invariant> yeah I wish there was another way to twirte proof, some sort of hand waving magic way
19:56:57 <Vorpal> elliott, take http://sporksirc.net/~anmaster/minecraft/screenshots/overhang/2010-12-23_19.57.42.png for example. That are two huge overhangs next to each other, not a full arch
19:57:00 <elliott> j-invariant: yeah like writing some stuff on paper, saying "the rest is left as an exercise to the reader", and calling it a day
19:57:05 <elliott> j-invariant: why do we need computers to do it anyway!
19:57:15 <elliott> Vorpal: heh
19:57:41 <Vorpal> elliott, the rest of the pictures in that dir are quite nice too, showing off the THIRD huge overhang which is hidden in the picture I linked.
19:57:58 <elliott> j-invariant: I think that maybe "x = tt" is easier to work with than "if x then True else False"
19:58:36 <j-invariant> lol
19:58:49 <Vorpal> elliott, you can't get up on one of them because it overhangs all around
19:59:00 <Vorpal> elliott, the other two (including the largest one) you can get up on just fine

20:03:00 <j-invariant> Qlt I mean
20:03:11 <elliott> j-invariant: a second omega? it wouldn't even run once, because of that
20:03:22 <j-invariant> import QArith and stuff?

20:38:46 <elliott> for a computable dedekind cut
20:39:08 <elliott> j-invariant: so it must be true, by wikipedian infallibility
20:39:18 <elliott> j-invariant: i think ic an hack the proof if youc an make "rewrite Znot_le_gt in H1" work :P
20:42:39 <j-invariant> tested it in haskell and found no counter example

20:47:11 <Vorpal> elliott, well yes
20:47:16 <elliott> coq has a ton of automatic solvers, none of them want to touch this :)
20:47:21 <Vorpal> elliott, ah...
20:47:22 <elliott> as far as i can tell
20:47:43 <Vorpal> elliott, I was thinking about using something like alt-ergo or cvc3
20:47:45 <elliott> step one is finding an s that satisfies
20:48:07 <elliott> j-invariant: any ideas about what s to try? :p
20:48:42 <Vorpal> elliott, what exactly are you trying to prove? I don't know co
20:48:43 <Vorpal> coq*
20:49:15 <elliott> Vorpal: i'm trying to prove that D(p/q) = p^3 <= 3*(q^3) is a (computable) dedekind cut
20:49:24 <elliott> proving that it's the cube root of three is for after i have arithmetic. :p
20:49:39 <elliott> Vorpal: i.e. Yet Another approach to the computable reals
20:49:50 <Vorpal> elliott, I guess I can't help until I first check what the heck dedekind cut is
20:50:01 <elliott> Vorpal: you ... don't know?
20:50:07 <Vorpal> elliott, can't say I do no
20:50:24 <elliott> Vorpal: http://en.wikipedia.org/wiki/Dedekind_cut
20:50:28 <elliott> they're the "usual" definition of the reals
20:50:45 <elliott> Vorpal: the computable version is described in http://en.wikipedia.org/wiki/Computable_number#Formal_definition starting "There is another equivalent definition"
20:50:48 <Vorpal> oh right, the definition is familiar
20:50:55 <Quadrescence> Vorpal: hi
20:50:55 <Vorpal> elliott, but I don't think I ever heard it's name
20:51:09 <elliott> Vorpal: *its
20:51:14 <Deewiant> "Usual"?
20:51:21 <elliott> Deewiant: well, i'd say so
20:51:23 <Vorpal> Deewiant, well not sure about that.
20:51:32 <elliott> Deewiant: dedekind cuts and cauchy sequences are the main ways
20:51:32 <Quadrescence> elliott: that's not an approach to computable reals
20:51:39 <elliott> Quadrescence: what aren't?
20:51:45 <Quadrescence> elliott: whatever you're doing
20:51:45 <Deewiant> I'd say the Cauchy sequence definition is far more common
20:51:54 <Vorpal> elliott, the second one really cauched on!
20:51:56 <elliott> Deewiant: that may be so
20:52:06 <elliott> Quadrescence: that's both unhelpful and unjustified
20:52:06 <Vorpal> (sorry, but oerjan wasn't here)
20:52:25 <Quadrescence> elliott: if you want computable reals, you have to start talking about bounds and turing machines
20:52:40 <elliott> Quadrescence: I know what computable reals are. There are several approaches.
20:52:56 <elliott> e.g. approximation functions, continued fractions, and this one, computable dedekind cuts
20:53:25 <Quadrescence> "computable dedekind cuts" sounds like a terrible idea
20:54:04 <elliott> Quadrescence: on what grounds?
20:54:06 <j-invariant> actually what are computable reals?
20:54:11 <elliott> j-invariant: reals that are computable :-)
20:54:20 <j-invariant> elliott: yeah but that's too vauge
20:54:21 <elliott> Vorpal: clever use of shadows to give 32-colour images in minecraft: http://www.minecraftwiki.net/images/c/c4/Dither2.jpg
20:54:33 <Quadrescence> j-invariant: a number which there is a finite process for computing the digits of to arbitrary precision
20:54:35 <Slereah> Markov made a nice article on that
20:54:37 <elliott> "In mathematics, particularly theoretical computer science and mathematical logic, the computable numbers, also known as the recursive numbers or the computable reals, are the real numbers that can be computed to within any desired precision by a finite, terminating algorithm. Equivalent definitions can be given using μ-recursive functions, Turing machines or λ-calculus as the formal representation of algorithms."
20:54:42 <elliott> there are tons of definitions i'd say
20:54:46 <elliott> but they're all equivalent. probably
20:54:47 <j-invariant> are they all equivalent?
20:54:53 <elliott> well, wp says so.
20:55:08 <Slereah> A computable number was basically just defined as (f(x) - g(y))/h(z)
20:55:18 <Slereah> Where all three functions are computable processes
20:55:28 <Quadrescence> :|
20:55:39 <Slereah> Owait
20:55:52 <Slereah> (f(x) - g(x)) / (1+h(x))
20:56:16 <Quadrescence> :|
20:56:21 <Slereah> wot
20:56:57 -!- augur has changed nick to YeshuaLord.
20:57:19 -!- YeshuaLord has changed nick to augur.
20:57:55 <elliott> ineiros: Can I have some bacon?
21:00:34 <Quadrescence> also Deewiant is certainly right that the cauchy seq. defn is the usual defn of the reals
21:00:45 <elliott> sure, but dedekind cuts aren't actually niche.
21:01:14 <j-invariant> I always thought I was alone with my cauchy sequences
21:01:38 <Slereah> Who cares about the reals
21:01:44 <elliott> http://en.wikipedia.org/wiki/Construction_of_the_real_numbers damn, wp lists dedekind second
21:01:47 <Slereah> The whole set of reals is useless!
21:01:51 <elliott> quick, let's edit it to prove Quadrescence wrong
21:02:05 <Slereah> Aleph one of it is basically not found in nature!
21:02:26 <Quadrescence> elliott: No, my evidence is from reading books
21:02:30 <Quadrescence> not Wikipedia all day
21:02:36 <elliott> wikipedia disproves all books, obviously
21:03:27 <Slereah> Cauchy sequence may be first because it's the most intuitive?
21:03:47 <Quadrescence> PROBABLY
21:05:08 <pikhq> 3 math classes. :D
21:14:40 <elliott> Vorpal: notch should reintroduce holes in the bedrock, except make them correspond to holes in the nether ceiling
21:20:41 <elliott> Vorpal: :( he's going to add degrade-on-hit
21:21:02 <elliott> Vorpal: there's a creeper jumping outside my door
21:25:21 <Vorpal> <elliott> Vorpal: :( he's going to add degrade-on-hit
21:25:21 <Vorpal> err
21:25:25 <Vorpal> elliott, what do you mean
21:25:39 <elliott> Vorpal: as in, your pick can break midway through mining obsidian
21:25:42 <elliott> because it's every hit that degrades it
21:25:59 <Vorpal> elliott, what the...
21:26:09 <Vorpal> elliott, so it won't last as long as before?
21:26:12 <elliott> sure it will
21:26:18 <elliott> the damage will be less
21:26:25 <elliott> also, apparently block damage will last for like 10 seconds after you stop mining
21:26:25 <Vorpal> ah
21:26:30 <elliott> so you have time to change to a new pick
21:26:30 <elliott> but still
21:26:34 <elliott> i liked degrade-on-break
21:26:44 <Vorpal> elliott, not as bad then as it could be
21:27:21 <Vorpal> elliott, change to peaceful?
21:27:29 <elliott> Vorpal: on SMP?
21:27:34 <elliott> i killed it anyway
21:27:36 <elliott> easy enough
21:27:36 <Vorpal> ah
21:27:55 <elliott> waiting for someone to log in, kill some pigs, and share the bacon with me; I'll provide lodging in my house in return
21:27:58 <Vorpal> elliott, well I'm waiting for the old world. Not really worth building anything in the current world
21:27:59 <elliott> Only 2.5 hearts left :/
21:27:59 -!- impomatic has left (?).
21:28:12 <elliott> Vorpal: no reason this world can't be brought out occasionally
21:28:19 <elliott> it's fun, i've already built a tall house
21:28:28 <elliott> and will mine once i can get coal for torches
21:28:31 <Vorpal> elliott, see, I like predictability
21:28:40 <elliott> what?
21:29:30 <Vorpal> elliott, "logging on thinking you will work on whatever your current project is. Huh, what, not the usual world?!"
21:29:43 <elliott> Vorpal: Or we could have it on predictable days ...
21:29:48 <elliott> Say every two weeks or something.
21:30:05 <elliott> If you're going to say "no just trash it permanently": I built a house I like too, you know.
21:30:14 <elliott> Except mine's in the survival world.
21:30:35 <Vorpal> elliott, well, donate to ineiros so he can get a good VPS to run all the servers on side by side
21:30:44 <elliott> Or just have the survival world come out at predictable times.
21:30:59 <Vorpal> elliott, but yes I think we should switch world whenever you feel like working on glass cube
21:31:12 <Vorpal> that sounds good, switch away from the glass cube one then
21:31:48 <elliott> Vorpal: Are you just trying to be a dick, or are you really so dense that you'll demand that the peaceful world is kept constantly because of ~YOUR BEAUTIFUL HOUSE~ while completely disregarding the fact that I've built things in the survival world, too, and plan to continue doing so?
21:32:22 <Vorpal> elliott, but you are the only one who built stuff there
21:32:26 <Vorpal> elliott, you against all the other ones?
21:32:47 <elliott> Vorpal: I didn't say "trash the peaceful world".
21:32:50 <elliott> I said "have the survival world occasionally".
21:33:05 <elliott> Besides, the beta update for hMod won't be out for a little while, and this is only the first day of the survival server.
21:33:14 <Vorpal> elliott, yeah, maybe one day per moth
21:33:16 <Vorpal> month*
21:33:24 <Vorpal> elliott, or whenever hmod breaks due to upgrade
21:33:30 <Vorpal> the latter seems fair
21:33:41 <elliott> Vorpal: I agree, let's only have your house when hMod breaks.
21:34:25 <Vorpal> elliott, ... the other way around
21:34:42 <Vorpal> elliott, but I predict it will break fairly often
21:34:43 <elliott> Ahh, I see; your house is worth more because you made it.
21:34:45 <elliott> Your arguments, they are stellar.
21:34:51 <Vorpal> elliott, no it is the hmod world.
21:35:05 <Vorpal> elliott, further, it also happens to contain a LOT more
21:35:09 <Vorpal> built by other people
21:35:19 <Vorpal> elliott, fizzie, nailor, ineiros, PH and so on
21:35:36 <Vorpal> elliott, so you hate the "wonder's of the world" thing.
21:35:58 <Vorpal> (if you strawman me, then you get the same shit back)
21:36:01 <elliott> j-invariant: any luck?
21:39:25 -!- zzo38 has joined.
21:39:45 <j-invariant> elliott: the proof is 3 lines :D
21:39:48 <Vorpal> elliott, or you could just switch topic...
21:39:50 <Vorpal> like you did
21:39:58 <elliott> j-invariant: of what?
21:40:02 <elliott> which part i mean
21:40:13 <j-invariant> equivalence relation on natural transform
21:40:22 <elliott> oh, not my dedekind cuts :P
21:40:28 <elliott> right
21:40:30 <elliott> cool, though
21:42:08 <elliott> j-invariant: have you seen http://coq.inria.fr/stdlib/Coq.Logic.IndefiniteDescription.html?
21:43:21 <elliott> ineiros: I'll bribe you for bacon. :p
21:43:46 <Gregor> elliott: In retrospect, cunionfs is awesome :P
21:44:25 <elliott> Gregor: What's so awesome about it? :p
21:44:44 <zzo38> I should make a program to copy a CD/DVD with error emulation and other options. In case of error, it makes a error emulation file that the driver will emulate errors when reading the copy.
21:45:57 <elliott> Gregor: I'm considering writing a package manager based on it, please tell me it actually works well >_>
21:46:26 <Gregor> elliott: Oh it works fine, that's never been the issue, it just doesn't do much (it's just a per-process union FS)
21:46:32 <zzo38> Also a function to tell it to copy the entire disc even if it says only part of it has data, try copying everything anyways even if it says nothing there.
21:47:30 <Gregor> elliott: But what I imagine it's most useful for is building packages in a constrained environment where you don't want "smart" configuration dragging in dev packages you didn't want.
21:48:28 <Gregor> elliott: As well as, of course, "enterprise"y environments like I said before.
21:48:32 <elliott> <Gregor> elliott: But what I imagine it's most useful for is building packages in a constrained environment where you don't want "smart" configuration dragging in dev packages you didn't want.
21:48:36 <elliott> ITT: Debian and Fedora both have this
21:49:10 <Gregor> Yeah, but they do that in a fairly-bizarre way, this is just "let me see this, OK now they're in /usr"
21:49:24 <elliott> Gregor: So can you mount / as a cuneiformfs? :P
21:50:00 <Gregor> I was thinking about that, and my answer is yes-and-no. You could, if you're willing to do that first-thing then do (most) everything else under chroot.
21:50:46 <Gregor> The only real problem is that the directories you mount under it need to exist, but for them to exist they need to be in another FS (to be unioned in)
21:52:18 <elliott> <Gregor> I was thinking about that, and my answer is yes-and-no. You could, if you're willing to do that first-thing then do (most) everything else under chroot.
21:52:19 <elliott> switch_root
21:52:22 <elliott> silly
21:52:27 <elliott> it's what initramfses do IIRC
21:52:38 <elliott> and it pulverises your existing / :P
21:52:45 <Gregor> That doesn't resolve the issue I mentioned later.
21:53:06 <Gregor> The directories you're going to mount /other/ filesystems to need to exist, but for them to exist, they need to ... already exist :P
21:54:08 <pikhq> Hello there.
21:54:22 <pikhq> To have two degrees instead of 1, I need: 1 extra class.
21:56:18 <j-invariant> elliott: http://coq.pastebin.com/xnGjabR6 line 481
21:57:02 <j-invariant> don't look at lines nera 200 :P
21:57:26 <j-invariant> that stuff is awful but I don't know a better way
21:57:49 <elliott> j-invariant: i like it, i also think that it will never work as an stdlib :D
21:58:34 <j-invariant> elliott: I'm going to try to define universal cones so I can get things like products
21:59:28 <elliott> sounds good
21:59:45 <elliott> Gregor: For a stow-alike, are there any advantages to cunionfs over unionfs? :p
22:00:00 <j-invariant> why wont it work as a stdlib?
22:00:08 <elliott> j-invariant: well it might with enough layering
22:00:16 <elliott> j-invariant: i just mean, if you have to build categories like that all the time
22:00:48 <j-invariant> elliott: I think (but I have to study this first) you can define a 'type theory' category, and just use that for everything
22:00:50 <Gregor> elliott: Yes, every process can see its own stowish environment, giving it the build advantage I mentioned before, as well as the ability to have conflicting packages installed simultaneously, etc. Whether that's an advantage to you depends on what you want *shrugs*
22:01:03 <elliott> Gregor: That's an sps-alike, not a stow-alike :P
22:01:15 <elliott> Gregor: But yeah, compelling.
22:01:22 <j-invariant> elliott: but that might be like defining a self interpreter for coq so..
22:01:25 <elliott> Gregor: Now guarantee that cunionfs is stable enough to use in Kitten :P
22:01:26 <Gregor> elliott: For a stow-alike, are there any advantages to unionfs over ... stow?
22:01:30 <elliott> j-invariant: yeah ...
22:01:34 <elliott> j-invariant: also it'd be rather abstract
22:01:37 <Gregor> elliott: I can't guarantee anything, it's F/OSS :P
22:01:38 <elliott> j-invariant: like coding ASTs manually
22:01:43 <elliott> Gregor: stow uses ... symlinks.
22:01:46 <elliott> Ask pikhq for the gory details.
22:01:57 <elliott> Note: Symlinks are pretty much the devil.
22:02:15 <elliott> Gregor: Well, half-guarantee then :P
22:02:15 <j-invariant> I would like to implement something like Knuth Bendix completion to automatically prove theorems
22:02:35 <pikhq> Gregor: GNU stow does nothing more than looking in the stow directory and checking for files that aren't symlinked into the path.
22:02:55 <Gregor> elliott: I have fair confidence that cunionfs is sufficiently stable, and that any stability issues are sufficiently minor that they could be fixed in short order.
22:03:10 <pikhq> It's not *terrible*, but it's only one step removed from Slackware's "untar things to root".
22:03:38 <elliott> Gregor: By you or me :P
22:03:41 <Gregor> pikhq: Well, it claims to be a package manager for people who don't want package managers, right? :P
22:03:53 <Gregor> elliott: By me if they're interesting :P
22:04:04 <elliott> Stow is the official package manager of the GNU Operating System.
22:04:07 <elliott> True story.
22:04:13 <elliott> And cpio the official archiver :P
22:04:17 <Gregor> elliott: Frankly, I'd very much like to see a package manager properly integrated with cunionfs, so it's in my best interest to be helpful.
22:04:40 <elliott> Gregor: Note: It would not plug into an existing package manager, it'd be an entirely new one based on cunionfs :P
22:04:44 <elliott> If you don't like it, SUX2BEU.
22:04:44 * pikhq is definitely going to end up with a dual major, then.
22:05:06 <pikhq> 3 credit hours extra for the freaking second major? Hells yes.
22:05:10 <elliott> pikhq: Mathematical Knitting and Advanced Haberdashery?
22:05:11 <Gregor> elliott: My integration with dpkg was ... spotty at best, mainly because dpkg (as with all other package managers) is wildly unsuited to union-based "transient" packages.
22:05:22 <pikhq> elliott: CS and mathematics.
22:05:33 <elliott> pikhq: U BORIN
22:05:45 <elliott> I would pay endless amounts of money for a degree in Advanced Haberdashery.
22:06:07 <elliott> Gregor: To be honest, the actual package manager part looks suspiciously close to "untar into /pkg/x" the way this is looking :P
22:06:08 * pikhq bestows upon elliott a B.A. in Advanced Haberdashery.
22:06:18 <elliott> pikhq: yæy
22:06:30 <Gregor> elliott: If it has SOME dependency management beyond that, that'd be nice :P
22:06:46 <Gregor> pikhq: I increasingly regret not getting a minor in archaeology when I had the chance :(
22:06:57 <elliott> Gregor: Yes, but the actual install part :P
22:07:09 <pikhq> Gregor: I could also pick up a minor in just about anything.
22:07:15 <pikhq> Gregor: Er, anything liberal arts-y.
22:07:17 <elliott> Sidenote on archaeology: Indiana Jones films -- 10x better if he sat there doing actual archaeology when shit was doing down? Answer: yes.
22:07:30 <pikhq> Gregor: You see, the liberal arts requirements are completely undefined.
22:07:41 <pikhq> Except in terms of credit hours needed.
22:07:48 <Gregor> elliott: I see no reason why the /install/ would be anything else, it's just the runtime choice of packages to union in that's interesting.
22:07:56 <Gregor> pikhq: Awesome. Awesome to the max.
22:08:19 <zzo38> How I would do it, is package manager operating by pipes. I would do it other programs are also operating by pipes.
22:09:58 <elliott> Gregor: Wait, you mean when you do "emacs" it should create a new union with ONLY THE THINGS EMACS NEEDS?
22:10:14 <elliott> Gregor: That has the major flaw that looking at /usr/bin with emacs would make me go wtf and get angry at my computer for being too smart :P
22:10:26 <elliott> Also bash.
22:12:01 <elliott> Gregor: Or is that not what you meant.
22:14:23 <elliott> Gregor: :|
22:15:33 <elliott> I hypothesise that Gregor cannot see his IRC client from inside his current process.
22:16:37 <j-invariant> frustrating: Terminal objects are defined by universal cones on the empty diagram... but universal cones are defined in terms of terminal object. So i have to define terminal objects twice

22:22:29 <j-invariant> mutual recursion is terrifying

22:25:26 -!- sshc has quit (Quit: leaving).
22:26:28 <Vorpal> elliott, any details?
22:29:45 <fizzie> Don't you mean: A New Kind of Mining.
22:30:45 <elliott> fizzie: Yes. I call it: Creeper mining.
22:30:50 <elliott> fizzie: It also works for cutting down trees.
22:31:30 <elliott> fizzie: Basically, you keep all your possessions in a chest. Then at night you walk out, see somewhere you'd like to mine/chop, and get a creeper there.
22:31:32 <elliott> Then you walk into it.
22:32:33 * Gregor reappears.
22:32:43 <Gregor> elliott: No, I do not mean that when you type "emacs", it should create a new union.
22:33:06 <elliott> Gregor: But that would be awesometerrible :P
22:33:47 <Gregor> elliott: The unions are, at the minimal, by process-level, but most users would probably opt to just have their own master list, and the system would presumably have a semi-compulsory list. Users could of course opt to make more/less restricted lists for individual processes if they so desired, but the default (for sanity) would be to /behave/ as a per-user package system, while providing sufficient abstraction for per-process.
22:34:45 <Gregor> Think of it like open fds: If you keep on opening new shit, it's going to have the same std{in,out,error}, unless you or it opt not to.
22:34:49 <elliott> Gregor: How does one actually add a new union?
22:35:40 <Gregor> elliott: CUNIONFS_DIRS environment variable, which (originally, Idonno if I reimplemented this in cunionfs (yet) or not) was backed by a per-user configuration file, backed by a per-system configuration file.
22:36:11 <Gregor> But since environment variables are passed exactly like fds, that abstraction fits best.
22:36:58 <elliott> Gregor: Hmm
22:37:07 <elliott> Gregor: Woo me with its features
22:37:17 <elliott> fizzie: The saddest creeper: standing in a tree, facing the leaves, so that it will never see anything.
22:37:54 <Gregor> elliott: I don't have sufficient motivation to try so hard; if you want each process to have its own unique and easily-malleable view of the FS, you want cunionfs. Otherwise, you don't.
22:38:17 <elliott> Gregor: I don't, but I do want semi-sane builds and stow-like package management :P
22:39:31 <Gregor> In my opinion "stow-like" is a bad compromise. So long as you have everything separated, there's no need to use something so clunky as a whole-system union to view it.

22:40:36 -!- zzo38 has set topic: The sillier you are to the batsman, the closer you are. | http://tunes.org/~nef/logs/esoteric/?C=M;O=D.
22:41:29 <Gregor> But then, once again, it comes down to needs/wants: If you want more flexibility in what individual users/processes/whatever sees, then you really don't have all that many options .. it's either a smarter unionfs or something that clunks together a bunch of PATH, LD_LIBRARY_PATH, CFLAGS, LDFLAGS, etc etc environment variables.
22:41:40 <Gregor> If you don't, don't use it :P
22:41:43 <elliott> <Gregor> In my opinion "stow-like" is a bad compromise. So long as you have everything separated, there's no need to use something so clunky as a whole-system union to view it.
22:41:50 <elliott> What would you have as the usual configuration, then, if not "all packages exposed"?
22:41:52 <zzo38> Do you have time now to review my TeXnicard program so far? http://sprunge.us/RgEZ
22:42:50 <Gregor> elliott: "All packages" could very well have conflicting packages in it. The default would be defined by the package manager. It would probably be what most distros consider a "task", or just whatever the system maintainer cared to make default.
22:43:44 <elliott> Gregor: I'm just saying that in general, 99.9% of the packages would be available, since two conflicting packages are rather rare to install
22:43:55 <Gregor> Remember, packages have versions too.
22:44:09 <elliott> Gregor: OK then, the default would be the largest set of non-conflicting packages or whatever.
22:44:12 <elliott> Gregor: But that's still stow-like
22:44:35 <Gregor> e.g. with stow, macports, etc you can have multiple versions of programs/libraries installed. Then you can swap them out when there are incompatibilities, bugs, whatever. A cunionfs-based system would let you work around such bugs on a per-process basis without having to do anything particularly crazy.
22:45:11 <Gregor> But once again, all the cases I've listed where cunionfs gives you advantages over something whole-system are sort of corner-cases, I just argue that there are sufficiently many such corner cases that giving the flexibility /might/ be worthwhile *shrugs*
22:45:31 <elliott> Gregor: To be honest, I'd go straight to unionfs if not for the nice-builds thing. That seems compelling to me.
22:45:43 <elliott> Hmm, well, how easy is it to change the union of a unionfs/aufs mount without umounting?
22:45:46 <elliott> If not easy: CUNIONFS IT IS
22:45:50 <ineiros> Anyone up for bacon?
22:46:01 <Gregor> elliott: I have no idea, probably not difficult.
22:46:04 <elliott> ineiros: Well. Uh. I sorta died enough that I have full health now. But you can come see my house!
22:46:34 <zzo38> ineiros: Why do you ask?
22:48:23 <pikhq> elliott: Not very hard; mount -o remount
22:48:34 <elliott> pikhq: Is there any window of not-workingness for the mount?
22:48:56 <elliott> Gregor: Still, I could avoid chroots entirely with cunionfs... right? For building, I mean.
22:49:05 <Gregor> Yes
22:49:24 <Gregor> You'd just say "give me these dev packages, OK now build"
22:50:06 <pikhq> elliott: The inodes aren't guaranteed to remain the same across a remount, but otherwise everything continues to work.
22:50:44 <j-invariant> elliott: I need to design a language for category theory (so I can automatically compute things like duals)
22:51:00 <elliott> j-invariant: yea
22:51:15 <zzo38> j-invariant: Do you have ideas how you can do that?
22:51:34 <j-invariant> zzo38: not yet but I am wondering if it could be done in terms of category theory
22:51:51 <zzo38> j-invariant: How much do you know of category theory?
22:53:04 <j-invariant> zzo38: I think I finally have the basic definitions down, but that took a long time
22:59:54 <j-invariant> but I think the mindset can take a long time to learn because a lot of things can be descrivbed in this language in a very conscice way which you would not expect
23:01:08 <Vorpal> elliott, like TNT, creepers destroy a percentage of the blocsk
23:01:11 <Vorpal> blocks*
23:02:28 <zzo38> Vorpal: What is the percentage?
23:06:55 <zzo38> Someone told me that Wikipedia will be removed. Is that true?
23:07:35 <j-invariant> zzo38: I doubt it unless there is a good reason
23:07:51 <j-invariant> without an explanation there is no reason to beleive it
23:08:06 <zzo38> j-invariant: They told me it is because they have no more money.
23:08:15 <j-invariant> oh that sounds like a hoax
23:08:28 <j-invariant> dammit!
23:08:42 <j-invariant> I went to wikipedia to click on the advert bar.. now its gone
23:09:52 <zzo38> j-invariant: I look too and it is gone. I also looked in the meta and in the preferences and did not find information about it.
23:12:14 <Vorpal> j-invariant, the bar at the top of http://wikimediafoundation.org/wiki/Donate looks rather bad though
23:12:31 <j-invariant> bad? they have 12.5 million dollars
23:12:43 <zzo38> Vorpal: O, that is where they moved it to.
23:12:53 <Vorpal> j-invariant, oh wait, it needs js
23:12:53 <j-invariant> thanks Vorpal that's what I was looking for
23:13:03 <Vorpal> j-invariant, that looks very very different when I allow it in no-script
23:13:30 <elliott> oh i thought you were mentioning Vorpal for no reason XD
23:14:07 <Vorpal> elliott, who?
23:14:13 <Vorpal> (who was mentioning I mean)
23:14:16 <Vorpal> (zzo or j-inv)
23:15:03 <Vorpal> elliott, hm, I suspect you have me on ignore.
23:15:26 <Vorpal> oh well
23:15:46 <Vorpal> he can't take being wrong I guess.
23:16:41 <zzo38> Vorpal: But what if you are being unsure instead of just plainly wrong?
23:17:02 <Vorpal> zzo38, what? I'm not wrong. elliott is
23:17:17 <Vorpal> zzo38, please read what I actually wrote
23:17:22 <zzo38> Vorpal: I didn't mean you personally. I meant in general.
23:17:25 <Vorpal> ah
23:17:37 <Vorpal> zzo38, what about it
23:18:52 <zzo38> Vorpal: Maybe I am not writing clearly.
23:19:12 <Vorpal> zzo38, maybe.
23:23:38 <zzo38> Now review TeXnicard program! Tell me if there is any mistake, thing I forgot, opinion, question, etc. http://sprunge.us/RgEZ
23:23:52 <zzo38> And did you notice I changed a few words around in the topic message for this channel, today?
23:26:01 <zzo38> Tell me if (in your opinion) I did the random numbers correctly.
23:29:22 <ineiros> Vorpal, fizzie, elliott and others who might care: I put the normal world back up, without hMod. The backups are now unattended and done without turning the level saving off, so there's a good chance they won't all go as planned.
23:31:51 -!- MigoMipo has quit (Read error: Connection reset by peer).
23:42:09 <Vorpal> ineiros, heh
23:42:40 <Vorpal> ineiros, is it without monsters?
23:44:47 <elliott> ineiros: /msg
23:58:07 <j-invariant> elliott: "The concrete details of a given construction may be messy, but if the construction satisfies a universal property, one can forget all those details: all there is to know about the construct is already contained in the universal property" - quoted from Dear Learder Wikipedia
23:58:50 <j-invariant> so it's sort of like proof irrelevance, but for general constructions
23:58:51 <elliott> j-invariant: it's like a philosophy of life!
23:59:21 <elliott> j-invariant: hmm, that reminds me of how in non-dependent functional langs, you can encode values as their type's fold combinator
23:59:42 <j-invariant> that is the univesral property :P
23:59:55 <elliott> yeah
