00:00:34 <Deewiant> Why is it silly
00:00:59 <oerjan> elliott: well it is clearly a link to the FUTURE
00:01:10 <elliott> Deewiant: because it's an empty promise?
00:01:16 <elliott> it's not going to be a useful link for ages, so it's rather pointless
00:01:53 <zzo38> elliott: Your IRC client must have some way to enter another command to IRC server though, it depends on the client. The FLUSH command I implemented can take only one parameter anyways.
00:02:45 <Deewiant> The cost of linkifying is low compared to the potential uses; it might be unlinkified for a long time after the page goes up, which is a greater loss
00:04:11 * oerjan ponders making a joke page for Feather
00:07:27 <elliott> '''Feather''' is like... ''whoa,'' man...
00:07:35 <elliott> Deewiant: RED IS UGLY
00:07:36 * oerjan is writing now
00:07:47 <Deewiant> elliott: Use custom CSS.
00:07:53 <elliott> Deewiant: ;_;
00:07:58 <elliott> oerjan: psht, if you weren't an admin i'd ask for it to be deleted :D
00:09:09 <oerjan> i _am not_ an admin
00:09:49 <elliott> oerjan: oh, indeed :D
00:11:10 <elliott> hm how many characters do you need to store an sha512 digest
00:11:24 <elliott> 64, it seems
00:16:24 <zzo38> Is there anything wrong with the C-LONG beer program?
00:18:14 <zzo38> And do you have anything to say about TeXnicard anyways?
00:20:41 <oerjan> elliott: that was some fast editing
00:21:15 <elliott> oerjan: i just clicked the red feather link and saw you'd already created the page :)
00:21:17 <elliott> pure coincidence
00:21:24 <elliott> one might even say ... SYNCHRONICITY
00:21:30 * elliott gets switten
00:21:50 <elliott> (those who are swatted are switten)
00:22:12 <oerjan> elliott: heh. but you managed to do it between me saving the page and refreshing Recent Changes
00:22:19 <elliott> heh
00:22:29 <oerjan> which must have been less than half a minute
00:38:53 -!- Sasha2 has quit (Read error: Connection reset by peer).
00:38:59 -!- Sasha has joined.
00:45:00 <quintopia> this reminds me of mel brooks's luggage in space balls: http://www.buzzfeed.com/gavon/top-25-gawker-passwords
00:47:33 -!- Wamanuz has quit (Ping timeout: 250 seconds).
00:47:34 <Ilari> Heh... Wonder why ping times on this LAN link are so asymmetric and growing: In the start the ping times were about 0.5ms and 0.6ms. Now those are about 11.0ms and 1.7ms (resp.)
00:49:16 <elliott> quintopia: "Top 25 Gawker Passwords"? Seriously?
00:49:29 <elliott> If writing "Top" and then a number was banned on the internet, I would be a happy man.
00:49:38 <oerjan> Ilari: gravitional time dilation. check if one of the servers has become a black hole
00:49:49 <elliott> oh wait
00:49:51 <elliott> it's literally, most popular
00:49:54 <elliott> not "best" :D
00:49:58 <quintopia> heh
00:50:04 <Ilari> Aren't pings round trip times?
00:50:34 <quintopia> divided by 2, usually
00:51:07 <Ilari> Anyway, there's factor of ~6 difference in round-trip times...
00:51:40 <Ilari> And variability between pings is very small...
00:52:11 <elliott> quintopia: erm are you sure ping times are divided
00:52:43 <elliott> quintopia: they're not, since they're round-trip times
00:52:53 <elliott> not sure why you said they were divided by 2.
00:53:26 <Ilari> It isn't time measurement drift: Starting another ping shows the same kind of RTTs.
00:53:31 <elliott> quintopia: ?
00:54:36 <Ilari> Actually, both times grew at start, but now that lesser time appears to have reached saturation whereas the bigger one continues to increase...
00:56:44 <Ilari> Also, pings to IPv6 address of the same host are fast (~0.6ms).
00:59:04 <elliott> Gregor: http://sprunge.us/JYDZ Please tell me how silly I am.
01:00:16 <Ilari> BTW: IPSec slows down RTT by about 0.3ms. :-)
01:04:36 <quintopia> elliott: i misremembered, i guess
01:04:43 <elliott> ok
01:06:47 <Ilari> => IPSEC doubles the latency for me... :-)

01:17:15 <Gregor> Must ... kill ... everyone ...
01:18:29 <elliott> Gregor: wat

01:23:36 <Ilari> What's the minimum worst case bound for number of UTF-8 characters required to store SHA-512 hash? :-)
01:24:57 <elliott> Ilari: 64, surely
01:25:02 <elliott> Ilari: if they're all in ASCII range
01:25:25 <elliott> Ilari: well, presumably you mean the actual raw hash in base 256
01:25:26 <elliott> but maybe not
01:26:55 <elliott> Vorpal: these look nice: http://www.retributiongames.com/quandary/
01:27:59 <elliott> Vorpal: heh i like this: http://www.minecraftforum.net/viewtopic.php?f=25&t=46707
01:28:12 <zzo38> Please read this and tell me how crazy I did this: http://zzo38computer.cjb.net/textfile/miscellaneous/computer_cricket
01:30:19 <Ilari> Ah, not UTF-8 characters, but UTF-8 bytes. It seems the number is 72, 73 or 74.
01:30:52 <zzo38> The FPGA is no good unless there is sufficient public information available to create and upload the files to the FPGA without using any software you didn't write.
01:31:04 * oerjan thinks "minimum worst case" looks a _teeny_ bit oxymoronic
01:37:16 <elliott> zzo38: methinks many people would disagree ...
01:38:19 <zzo38> elliott: Why?
01:38:29 <elliott> because it's silly to say that?
01:38:43 <zzo38> elliott: Why?
01:38:57 <elliott> zzo38: because FPGAs are useful even without meeting that condition
01:39:49 <zzo38> But it is better if it does meet the condition I wrote.
01:40:29 <pikhq> I love not studying for finals.
01:40:57 <elliott> pikhq: "Laziness + weak hash tables + dynamic scope + side effects = heisenbug. Made a race condition look like an off-by-one error."

01:41:13 <elliott> (And then FIGURE OUT what a bug involving them is.)
01:41:22 <zzo38> Did you read my other message? Do you think the umpire is really a vampire?
01:41:23 <pikhq> elliott: Oh holy mother of god.
01:41:33 <elliott> pikhq: Indeed.
01:52:36 <elliott> pikhq: Please recommend me an alternative to /r/programming that isn't Slashdot.
01:54:58 -!- quintopia has changed nick to RadioBotStreams.
01:55:04 <pikhq> #esoteric
01:55:27 -!- RadioBotStreams has changed nick to quintopia.
01:55:56 <quintopia> yeah pretty much #esoteric
01:56:41 <elliott> yeah, but I generate most of the links in #esoteric... from /r/programming :)
01:56:46 <elliott> I want something where I don't have to do the filtering work, dammit!
01:58:04 <quintopia> you are looking for programming-related news links?
01:58:36 <elliott> quintopia: pretty much... although more a CS bent
01:58:41 <elliott> but yes, programming links.
02:00:06 <Ilari> That minimum worst case is actually well defined. Consider all functions that map all 2^512 SHA-512 hashes to UTF-8 strings. For each function f, there is maximum number of bytes in resulting UTF-8 strings (L(f)). Now what is the minimum of L(f) over all possible choices of f?
02:01:51 <quintopia> elliott: start going to conferences :P
02:02:31 <elliott> quintopia: that costs rather more money than the £0 I currently spend on programming links, involves a lot more travelling that probably doesn't fit into my life, and involves a lot more boredom and time passing, too
02:02:37 <Ilari> It is at most 74 because one can split 512 bits into 74 blocks of 7 bits each, and one can encode each block using a single ASCII character (which is subset of UTF-8).
02:02:54 <quintopia> elliott: but you'll always be on the bleeding edge of CS news
02:03:20 <elliott> quintopia: i can get the same from reading random arxiv papers, I want a filter, dammit
02:03:39 <quintopia> (more seriously, there aren't many places out there where you don't have to separate the signal from the noise yourself...even conferences have some crap)
02:04:08 <Ilari> The lower bound of 72 comes from the fact that entropy of UTF-8 is ~7.1756 bits per byte, giving lower bound of ~71.353 bytes (which rounds up to 72 bytes).
02:04:30 <elliott> quintopia: yes, but /r/programming is significantly worse than it used to be.
02:05:52 <quintopia> elliott: figure out who is making it worse and get them kidnapped by ethiopian pirates?
02:06:25 <elliott> your solutions, always so practical.
02:07:25 <quintopia> i wonder...
02:09:17 <elliott> what
02:10:11 <quintopia> elliott: news.ycombinator.com?
02:10:48 <Ilari> Okay, I computed the exact low bound: 73.
02:10:48 <elliott> quintopia: i know of it.
02:10:58 <quintopia> how is it?
02:11:05 <elliott> Quadrescence: sure, it is generally better than reddit -- but on the other hand, it's coated with the startup mindset
02:11:09 <elliott> ugh *quintopia:
02:11:31 <elliott> quintopia: meaning, lots of stupid business articles I don't care about, lots of rubbish startup-related things I don't care about, and more links than I'd like to WEB 2.0 crap
02:11:36 <elliott> (WEB 2.0 is shouted there.)
02:12:30 <elliott> "Facebook intern visualizes friendships, draws world map" "HN: We're starting a "Move to Silicon Valley" wiki. We could use some help." "The Anatomy of a Perfect Landing Page" "Commute to work like a boss, fly there" <-- first things on the current front page that i really don't care to see
02:12:37 <elliott> quintopia: i mean, the programming links are better than reddit's. and the comments too.
02:12:54 <elliott> quintopia: but there's more completely-unrelated-to-programming crap than /r/programming, and it's more irritating than reddit's non-programming crap
02:13:02 <quintopia> elliott: write a simple software filter on top of their rss feed :P
02:13:21 <elliott> quintopia: unfortunately i have not yet written a program to classify the topic of statements from their text by interpreting them
02:14:15 <quintopia> i know someone who has. he implemented it from another paper, and is sending me a writeup on wed.
02:14:51 <quintopia> classifies with 97% accuracy in a 3-fold cross-validation
02:15:56 <elliott> quintopia: "Commute to work like a boss, fly there" -- how on earth would you classify this is "non-programming"
02:16:10 <elliott> it's near the level of AI to identify that as non-programming without also filtering out a lot of programming links
02:16:58 <quintopia> well, you'd need to look at the actual article
02:17:08 <quintopia> it takes a certain number of features
02:17:30 <elliott> quintopia: i doubt i could get past a paywall.
02:17:30 <quintopia> ~100 words is usually enough
02:17:43 <elliott> quintopia: you realise that classification algorithms are not a new thing?
02:17:50 <quintopia> elliott: could you get past a paywall anyway?
02:17:55 <elliott> they won't categorise Hacker News for me.
02:18:04 <elliott> quintopia: i'm saying that it's pointless mentioning it without linking the paper
02:18:17 <quintopia> no, but if you take a significant subset of HNews and classify it manually, then they can
02:18:36 <Ilari> For SHA-256, the similar number is 37. And for Skein-1024, 144.
02:19:03 <quintopia> oh, you misunderstood me
02:19:07 <elliott> Ilari: what about cubehash :)
02:19:11 <Gregor> elliott: So have you renamed it to scape🐐 yet?
02:19:15 <elliott> quintopia: I did?
02:19:16 <elliott> Gregor: nope!
02:19:25 <Gregor> elliott: DOOD WHY NOT
02:19:32 <quintopia> i meant, your learning algorithm would need to look at the actual article linked from HNews in order to get enough data to classify
02:19:35 <elliott> Gregor: VARIOUS REASONS
02:19:37 <elliott> quintopia: oh.
02:19:44 <elliott> quintopia: that would eat my bandwidth :)
02:20:04 <quintopia> ...how often do new articles get posted?
02:20:14 <quintopia> looks like at most every 10 min
02:20:30 <elliott> quintopia: way more often than that, they just don't all get promoted to the front page
02:20:38 <quintopia> oh
02:20:39 <elliott> see /newest
02:20:47 <elliott> quintopia: i don't want it using my bandwidth when i'm not viewing it, anyway!
02:20:50 <Gregor> elliott: TOO VARIOUS IF YOU ASK ME
02:20:53 <elliott> so it'd have to do it all at once --> slow
02:20:58 <Ilari> Oops, 36 (256 bits), 72 (512 bits) and 143 (1024 bits)... :-/
02:21:00 <elliott> Gregor: maybe if you write some code for it i'll CONSIDER it
02:21:24 <quintopia> elliott: best to have it hosted on a remote server then :P
02:21:33 <elliott> quintopia: or just keep reading reddi
02:21:34 <elliott> t
02:22:19 <Gregor> elliott: How about if I just register goatpettingzoo.com and don't put goat porn there?
02:22:30 <quintopia> elliott: does that mean you're gonna stop whining about /r/programming's slow decline?
02:22:34 <elliott> Gregor: X-D
02:22:49 <elliott> quintopia: can you link to clog log dates when i have whined about it?
02:22:56 <elliott> OH RIGHT there's actually only one and it's today.
02:23:07 <quintopia> easy enough to link then :P
02:23:49 <quintopia> but complaining about something when you're not willing to work to improve is useless even if it's only once
02:24:02 <elliott> quintopia: what am i expected to do, start my own fucking site?
02:24:11 <elliott> i said that /r/programming is going to shit and *asked for alternatives*
02:24:11 <quintopia> :D
02:24:12 <quintopia> please?
02:24:25 <elliott> no, i already have a design for a reddit-based site and it relies fundamentally on nobody knowing about it
02:24:28 <quintopia> yes, but there are no alternatives :P
02:24:29 <elliott> *reddit-like
02:24:35 <elliott> quintopia: then just say that?
02:24:42 <elliott> quintopia: you whine about me whining way more than i actually whine
02:25:05 <quintopia> unlikely
02:25:22 <elliott> quintopia: well, it's the same order of magnitude
02:25:47 <zzo38> Do you know what yakitori penalties are?
02:26:03 <Ilari> Restricting to BMP doesn't change the figures (36/72/143).
02:26:40 <elliott> Ilari: why on earth are you calculating this :)
02:26:49 <Ilari> Just for fun... :-)
02:27:23 <Ilari> And it is considerably easier than computing the exact expression for the entropy of UTF-8 bytes. :-)
02:28:16 <zzo38> Ilari: What is the entropy of UTF-8?
02:28:19 <Ilari> Since you need to solve one root of 4th degree polynomial (that doesn't have rational root) for that...
02:29:02 <elliott> Ilari: BAH! Throwing things at Wolfram Alpha solves all problems.
02:29:08 <quintopia> ...just expressing the polynomial and saying which root it is would be an exact expression, nay?
02:30:33 <Ilari> The polynomial is x⁴-128x³-1920x²-61438x-1048544=0 and the root in question is the root in the interval [128,256].
02:32:25 <Ilari> Take base 2 logarithm of that and you get the entropy in bits per byte.
02:32:41 <oerjan> 144.56765801397
02:33:03 <elliott> oerjan: fuck you, i was just doing that :)
02:33:05 <zzo38> OK.
02:33:07 <elliott> "solve x⁴-128x³-1920x²-61438x-1048544=0, 128 <= x <= 256"

02:33:29 <oerjan> elliott: i happened to have a src0 function in one of my haskell files
02:34:15 <elliott> Ilari: 7.1756 bits of entropy per byte
02:34:18 <elliott> oerjan: ha i did the last step before you
02:34:37 <oerjan> elliott: only because i didn't even try, PHHH
02:34:39 <zzo38> Can anything have negative or complex number entropy?
02:34:45 <oerjan> or is that PPPH
02:35:00 <elliott> oerjan: what sound are you trying to express :P
02:35:02 <oerjan> zzo38: not in this sense
02:35:02 <elliott> zzo38: no. well negative maybe.
02:35:10 <elliott> if it's a black hole, say :D
02:35:37 <oerjan> is it called a raspberry sound?
02:36:11 <elliott> oerjan: "phhhhhhhbt"
02:36:13 <elliott> one would think
02:36:13 <zzo38> What is the sound of one raspberry clapping?
02:36:19 <oerjan> http://en.wikipedia.org/wiki/Blowing_a_raspberry
02:36:25 <oerjan> zzo38: DEEP
02:36:36 <elliott> oerjan: phhhhhhhbt
02:36:38 <elliott> i'd go for
02:37:13 <quintopia> wow. someone sold a web app for $350? lol
02:37:21 <elliott> quintopia: BIG BUX
02:37:32 <elliott> quintopia: i was offered IIRC $20 for the source to my digg#1 site :P
02:37:51 <oerjan> zzo38: although physically entropy might very well be negative given that afaik the zero point is an arbitrary choice
02:37:59 <elliott> (this being before digg went to shit... well ok it had gone to shit but not as much as it have now)
02:38:11 <oerjan> but informational entropy is not that way
02:38:46 <zzo38> oerjan: But what I mean is, can negative informational entropy have some meaning?
02:38:47 <oerjan> the macroscopic thermodynamic version of entropy only speaks of changes in it, not an absolute scale, iirc
02:39:12 <oerjan> i don't know
02:39:18 <zzo38> Make a esolang with negative (or complex number) informational entropy.

02:43:07 <zzo38> oerjan: OK.
02:43:40 <oerjan> you'd rather need some esoteric concept of information to calculate the entropy of, i think
02:44:22 <oerjan> there _is_ of course such a thing as quantum information theory which i know almost nothing about, i don't know if it has any nonnegative entropies
02:44:56 <elliott> oerjan is quantum

03:40:35 -!- Iwnda01 has joined.
03:40:56 <pikhq> Aaand Pidgin is crashing.
03:41:04 <pikhq> In its JSON parser‽
03:41:07 <pikhq> Why does it have one?
03:42:20 <oerjan> pikhq: that's not news
03:43:08 <pikhq> oerjan: No, but seriously. AIDS has been cured.
03:44:09 <oerjan> ...more than one person?
03:44:44 <Iwnda01> not to butt in but, there is no cure for aids.
03:45:25 <oerjan> argh!
03:45:28 <pikhq> oerjan: No, but only due to the expense.
03:46:03 <pikhq> It's fucking hard to hunt down a bone marrow donor that is genetically immune to AIDS, and this happened by chance.
03:46:12 <pikhq> Iwnda01: Yes there is.
03:46:12 <Iwnda01> not true. it's because HIV morphs so often it's apparently impossible to kill.
03:46:30 <oerjan> Iwnda01: do you even know the case we are talking about?
03:46:42 <Iwnda01> no i suppose i dont.
03:46:48 <Iwnda01> this would all be news to me.
03:46:49 <pikhq> Iwnda01: Bone marrow transplant with someone actually *immune* to the virus.
03:47:01 <pikhq> Iwnda01: Suddenly, all the immune cells in that person's body are immune to the virus.
03:47:06 <pikhq> And so HIV goes away.
03:47:10 <pikhq> Poof, cure for AIDS.
03:47:18 <Iwnda01> which person
03:47:53 <coppro> There are people genetically immune to AIDS
03:47:53 <pikhq> He was named only as "the Berlin patient" in the /New England Journal of Medicine/ and /Blood/.
03:47:58 <Iwnda01> and how would we find out if they are immune without infecting them and/or possibly killing them in the long run
03:48:03 <coppro> It's genetic
03:48:07 <coppro> you can devise a simple test
03:48:24 <oerjan> pikhq: i am pretty sure i saw a reddit post about him giving an interview under the full name
03:48:28 <Iwnda01> oh i see, remove the fluids and test out of the body
03:48:55 <Iwnda01> well he's got a trillion dollar body if he lives through all of the operations.
03:49:09 <coppro> it's not one person
03:49:17 <pikhq> Iwnda01: About 1% of Caucasians are immune to it, actually.
03:49:25 <Iwnda01> amazing.
03:50:05 <Iwnda01> that's great news
03:50:14 <Iwnda01> are they making any headway with it?
03:51:03 <Iwnda01> has anyone been cured?
03:51:13 <pikhq> Research on easier/cheaper ways of doing it are in progress.
03:51:39 <pikhq> And yes, a single person, who by *chance* needed a bone marrow transplant (leukemia), and his donor was immune to AIDS.
03:51:42 <oklofok> so we can finally have start having unprotected buttsex with strangers
03:51:44 <oerjan> http://www.aidsmap.com/page/1577949/?r=1 is the link currently on reddit
03:51:44 <pikhq> As I said earlier.
03:51:54 <oklofok> as a species
03:52:27 <Iwnda01> oklofok: that's looking at it with a hawks eye
03:52:34 <oerjan> oklofok: well you'd need to find an immune bone marrow donor first
03:52:59 <oerjan> Iwnda01: i think you may not be acquainted with oklofok's particular brand of humor
03:53:04 <oklofok> not really, you have like 50 years to do that once you get the virus
03:53:19 <Iwnda01> no i totally get him. i was just seeing which he was
03:54:04 <oerjan> oklofok: yeah but what if there _aren't_ any? compatible donors are probably rare, immune people are rare...
03:54:06 <Iwnda01> butt sex for everyone
03:54:11 <Iwnda01> who would want it...
03:54:38 <oklofok> actually this one time, doctors told me i absolutely must have chlamydia, but then turned out i didn't; my conclusion is i'm immune to all std's
03:54:57 <Iwnda01> oklofok: you're in tall cotton
03:55:13 <oklofok> Iwnda01: what does that mean?
03:55:18 <Iwnda01> I, oklofok, am also the king pin.
03:55:46 <oklofok> i don't get you at all
03:56:23 <Iwnda01> I guess I don't get you either
03:56:29 <Iwnda01> nice to meet you
03:56:30 <pikhq> oerjan: Uh, bone marrow donors are always compatible.
03:56:31 <oklofok> you can't not get me
03:56:37 <pikhq> oerjan: They start by removing your immune system.
03:56:38 <oklofok> pikhq: not in house
03:56:42 <oklofok> oh
03:56:58 <pikhq> The new bone marrow replaces it.
03:57:06 <oerjan> pikhq: oh they are? i guess that makes sense.
03:57:30 <oerjan> pikhq: in that case it should be possible to _grow_ immune bone marrow, shouldn't it
03:57:39 <pikhq> Possible.
03:57:41 <oklofok> i thought they stick a needle in the donor's back, take some shit outta there, and inject it in the other dude
03:57:45 <Iwnda01> stem cells?
03:57:45 <oklofok> poof done
03:57:51 <oklofok> Iwnda01: king pin?
03:57:52 <oerjan> Iwnda01: yeah
03:57:59 <oklofok> who else is the king pin?
03:58:29 <pikhq> oklofok: After irradiating & chemotherapying the receiver of the marrow to kill the bone marrow and the white blood cells.
03:58:33 <Iwnda01> will farrel
03:58:55 <oklofok> pikhq: have you even *watched* house?
03:59:10 <oklofok> because that sounds just crazy!
03:59:19 <pikhq> oklofok: I don't watch House, no.
03:59:33 <pikhq> oklofok: I prefer knowing how medicine actually works.
04:00:04 <Iwnda01> plus house has a terrible attitude

04:01:00 <oklofok> pikhq: what, you trust a dusty old ugly book more than SMART MEDICAL TYPE PEOPLE on tv?
04:01:24 <Iwnda01> judge not the book by its dusty ugly cover
04:01:41 <oerjan> oklofok: hey you cannot trust anyone who's been spending time with blackadder
04:01:44 <pikhq> oklofok: ^ This explains the entire American political, intellectual, and cultural climate.
04:02:09 <Iwnda01> but judge the book once you read it thoroughly.
04:02:16 <oklofok> i learn all my math on numb3rs

04:03:53 <oerjan> ok words to live by, very briefly
04:03:56 <Iwnda01> sounds about right
04:03:58 <pikhq> :)
04:04:21 <oklofok> some sort of hacking stuff probably.
04:04:28 <pikhq> oklofok: Math.
04:04:34 <pikhq> oklofok: It claims to be about math.
04:04:51 <oerjan> pikhq: which means it's probably about arithmetic?
04:04:59 <oklofok> i'm sure it *claims* that
04:05:00 <oklofok> haha
04:05:04 <oklofok> show about aritmetic
04:05:06 <pikhq> oerjan: No, it's about BULLSHIT.
04:05:28 <pikhq> oerjan: Imagine if Treknobabble were done using mathematics jargon.
04:05:31 <pikhq> That.

04:07:14 <pikhq> (SILC, perhaps, but IRC?)
04:07:33 <pikhq> Also, 1337.
04:07:57 <oklofok> that's actually the only clip i know
04:08:01 <oklofok> from the show
04:08:09 <oerjan> ...does 1337 have any interesting mathematical properties?
04:08:50 <pikhq> oerjan: No, it's an incredibly mundane substitution cypher.

04:11:57 <oerjan> hypothesis: 1337 is the smallest uninteresting number
04:12:01 <oklofok> :D
04:12:25 <pikhq> oklofok: It was a bizarre mangling of the Chinese Room thought experiment and the Turing Machine.
04:12:35 <pikhq> oerjan: Making it an interesting number.
04:12:37 <oklofok> yeah i'm still not sure what happened there
04:12:46 <oklofok> pikhq: that's the joke
04:12:48 <oerjan> pikhq: shush, you
04:12:58 <oklofok> the chinese room experiment is ... which is called the turing test
04:12:59 <pikhq> oklofok: EXPLAINING THE JOKE MAKES IT FUNNIER
04:13:04 <oklofok> pikhq: true
04:14:46 <oklofok> okay so yeah he just mentions perfectly programmed computer = turing test while explaining the chinese room experiment... i think
04:14:49 -!- Iwnda01 has left (?).

04:16:17 <oklofok> nope :(

04:21:33 <oklofok> i love this show, it's like watching puppies fighting to death
04:21:41 <oklofok> you know it's really wrong
04:21:43 <oklofok> but oh god
04:21:45 <oklofok> you can't stop watching
04:21:55 <pikhq> It seems to be so bad it's good.
04:34:24 <oklofok> okay i can't find any math related clips
04:34:28 <oklofok> maybe i should watch the whole show
04:34:50 <oklofok> the math guy has written articles in low-dimensional topology, so probably he talks about that stuff
04:35:26 <oerjan> yeah but only in a flat and linear way
04:36:16 <oklofok> noob, i work almost exclusively with 0 dimensional spaces
04:36:57 <oklofok> although i guess you did as well, but couldn't make a pun out of that
04:37:18 * pikhq prefers dealing with n-dimensional spaces where n is in N and less than 0.
04:37:21 <oerjan> i cantor i won't
04:37:28 <pikhq> (quick, someone make that make sense!)
04:37:39 <oklofok> there are many definitions of topological dimension
04:37:47 <oklofok> and i'm not sure any of them allow subzero dimensions
04:38:00 <oklofok> oerjan: was that yours?
04:38:01 <oerjan> oklofok: iirc many of them coincide for zero, though
04:38:05 <oklofok> yes
04:38:41 <oklofok> i know this fact very well because many of the ppl doing math in our uni are actually computer scientists, they don't even seem to care what the definition is, because they just work with 0 dim
04:38:47 <oerjan> well you can consider the empty set to have dimension -1
04:39:01 <oklofok> erm
04:39:22 <oklofok> with the recursive sphere definition at least
04:39:33 <oklofok> dimension = dimension of sphere + 1
04:39:37 <oklofok> for metrics
04:39:44 <oklofok> *metric spaces
04:40:37 <oklofok> what else is there.... d dimensions = open covers have a subcover where at most d+1 sets intersect at any given point
04:40:45 <oklofok> does it work with that...
04:40:54 <oklofok> yeah
04:40:56 <oklofok> perfectly
04:41:02 <oklofok> i think i'm getting an erection
04:41:17 -!- quintopi1 has joined.
04:41:21 <oklofok> i think i'm getting an erection
04:41:30 <oerjan> i believe that definition was the one used for the topological measures stuff
04:41:50 <oklofok> we used that in our ergodic theory seminar couple weeks ago
04:41:56 <oerjan> (you need dimension at least 2 for things to be non-trivial)
04:42:15 <oklofok> for showing something like topological entropy = sup of measure theoretic entropies for different measures
04:42:51 <oklofok> "<oerjan> (you need dimension at least 2 for things to be non-trivial)" <<< what do you mean?
04:43:23 <oklofok> i don't think that subcover thing is "trivial" for 1d
04:44:04 <oklofok> and for 0 it says that you can extract a clopen cover from any open cover... is that even true?
04:44:05 <oklofok> :D
04:45:01 <oklofok> i certainly didn't know that if it's true
04:45:26 <oklofok> oh
04:45:33 <oklofok> maybe it's for *refinements*
04:45:57 <oklofok> yeah obviously you can't always extract clopen covers
04:46:11 <oklofok> just take more than half the space in two open sets, but not all of it
04:46:17 <oklofok> then obv you need to take both, and get some overlap
04:46:23 <oklofok> for any definition of half
04:47:14 <oklofok> refinement being a family of open sets U such that each u \in U is a subset of an open set in the orig cover
04:47:36 -!- oerjan_ has joined.
04:48:13 <oklofok> also why am i here, i woke up at 5 so i could do some slides and then i just idle on irc
04:48:15 <oerjan_> 05:42 oerjan> at one time i _thought_ i had a proof that if you had dimension >= 2 then you _did_ have nontrivial topological measures but it didn't survive my blackboard demonstration :/
04:48:20 <oerjan_> 05:44 oerjan> ...what does that entropy supremum (i think i recall the theorem) have to do with dimension...
04:48:34 <oklofok> with leasurely topology technobabble
04:49:06 <oklofok> erm what
04:49:17 <oklofok> okay what's your definition of topological measure
04:49:25 <oklofok> because zero dimensional spaces have very nontrivial measures!
04:50:15 <oerjan_> ...i've explained it before, they're a topological generalization of lebesgue measures, which are only defined on open and closed sets
04:51:04 <oerjan_> and which only need to be additive on partitions of the whole space into open and closed sets
04:51:26 <oklofok> you mean into clopen sets?
04:51:32 <oklofok> and not into either
04:51:33 <oerjan_> no, either open or closed
04:51:35 <oklofok> okay
04:51:37 <oerjan_> each set
04:51:43 <oklofok> erm
04:52:05 <oerjan_> and only finitely many (although we have a theorem that countable also works)
04:52:11 <oklofok> so you say this thing is trivial for 0 dim and i assume the definition assumes a zero dimensional space :D
04:52:17 <oklofok> i'm smart ain't i :D
04:52:26 <oerjan_> this thing is trivial for <= 1 dim

04:59:30 <oklofok> i proved that's connected but not path connected in topology
04:59:33 <oerjan_> er, * x > 0 and x <= 1
04:59:39 <oerjan_> otherwise it's not compact
04:59:41 <oklofok> iir
04:59:41 <oklofok> c
04:59:48 <oklofok> erm
04:59:54 <oklofok> yeah
05:00:02 <oklofok> it's not path connected obv
05:00:22 -!- sshc has joined.
05:00:22 <oerjan_> indeed but it's not locally connected e.g. around (0,0)
05:00:23 <oklofok> but it's OBVIOUSLY connected
05:00:27 <oklofok> look i proved it again!
05:01:00 <oerjan_> because you need the entire height of the curve to connect different parts of it
05:01:06 <oklofok> yeah
05:01:08 <oklofok> i get it
05:01:14 <oklofok> i think
05:01:38 <oklofok> i mean i get it intuitively, but i'll have to think about the defs a bit
05:01:55 -!- quintopi1 has quit (Ping timeout: 322 seconds).
05:01:56 -!- ineiros has joined.
05:02:26 <oklofok> right you can't get ANY open set around origin
05:02:29 <oklofok> that's connected
05:02:54 <oklofok> locally connected doesn't imply connected? erm. of course it doesn't, disjoint union
05:03:19 <oklofok> you know this conversation of ours would already make a pretty good tv show
05:03:38 <oerjan_> >_>
05:03:52 <oklofok> i would watch that show
05:05:20 <oerjan_> anyway the strange properties of these measures depends on it _not_ being possible to approximately partition any open set into small open or closed parts that you can add up
05:05:41 <oklofok> and then all the youtube comments would be like "lol that's SO inaccurate, what he's saying is so totally only true if the measure has no atoms!"
05:06:26 <oerjan_> but dimension <= 1 is equivalent to saying every open covering can be refined into a partition of the space into open and closed sets
05:06:35 <coppro> win 27

05:06:42 -!- sshc has joined.
05:07:24 <oerjan_> (btw this theorem doesn't use any of the connectedness assumptions on the space)
05:07:38 <oklofok> the <= 1 one?
05:07:43 <oerjan_> yeah
05:07:51 <oerjan_> those are just needed to be able to construct examples nicely
05:08:22 <oklofok> hmm, i don't see why that thingie is true, but i suppose that's nontrivial?
05:08:32 <oklofok> okay if it's dimensions 0 and 1, then i'm sure it's nontrivial
05:08:48 <oklofok> because i don't know any properties those have others don't :d
05:09:02 <oerjan_> take that usual refinement of a dimension <= 1 space, then by definition the open sets only intersect at most 2 at each point
05:09:04 <oklofok> actually
05:09:06 <oklofok> you're right
05:09:13 <oklofok> for this to be a great tv show
05:09:22 <oklofok> we need like a really stupid fbi guy
05:09:27 <oklofok> who asks stupid questions
05:09:46 <oklofok> "so you're saying a locally connected spaces is like a rabbit that sticks its head into a bush when it gets scared?"
05:10:10 <oerjan_> argh
05:10:36 <oklofok> what? :D
05:10:42 <oerjan_> that fbi guy
05:11:23 <oklofok> okay walk me through it, how exactly do you make the partition
05:11:28 <oklofok> erm
05:11:34 <oklofok> or wait a minute
05:11:55 <oerjan_> now if you look carefully at this refinement, the points that are in two given sets are of course in the open set that is their intersection
05:12:11 <oklofok> take open cover's intersections with all others, plus it minus the union of all the others?
05:12:31 <oklofok> i guess not...
05:12:32 <oerjan_> huh?
05:12:44 <oklofok> okay so walk me through it, how do you make the partition
05:13:19 <oerjan_> on the other hand, the points that are in just _one_ given open set of the refined cover and not in any other, form a closed set
05:13:35 <oklofok> or continue your explanation whatever :D
05:13:37 <oerjan_> (the complement of the union of the other open sets)
05:13:41 <oklofok> wait
05:13:50 <oklofok> are you explaining exactly this...
05:13:52 <oklofok> let's look!
05:13:57 <oerjan_> but of course!
05:14:01 <oklofok> haha
05:14:09 <oklofok> i assumed you assumed i'd just see it
05:14:20 <oklofok> because it sounded so simple
05:14:33 <oerjan_> it's not hard if you draw the sets on paper
05:14:53 <oklofok> and have like 3d diagrams
05:14:57 <oerjan_> (of the refinement)
05:14:58 <oklofok> and flying numbers on the screen
05:16:07 <oklofok> "<oerjan_> on the other hand, the points that are in just _one_ given open set of the refined cover and not in any other, form a closed set" <<< this was the part i didn't see, but yeah it's obvious now that you stated it explicitly
05:16:23 <oerjan_> they form a bipartite graph, with the closed sets for the points in exactly one refinement set being one set of vertices, and the open sets for the points in _two_ refinement sets the other set of vertices
05:16:25 <oklofok> "<oerjan_> (the complement of the union of the other open sets)" <<< and even more obvious after you gave the proof
05:16:44 <oerjan_> and edges between sets that touch
05:18:06 <oklofok> hmm
05:18:19 <oklofok> that's true for all partitions gotten this way?
05:18:33 <oklofok> is that obvious again...
05:18:37 -!- quintopia has joined.
05:19:03 <oklofok> well of course it is
05:19:06 <oklofok> by definition of touch
05:19:29 <oklofok> wait
05:19:42 <oklofok> what's the definition of touch?
05:19:43 <oklofok> :D
05:19:47 <oerjan_> well you could alternatively say edges between sets that come partially from the same original refinement set
05:19:50 * oklofok is the fbi agent
05:19:54 <oklofok> okay
05:20:03 <oerjan_> but i believe that is equivalent
05:20:11 <oerjan_> touch = their closures intersect
05:20:18 <oklofok> by "original refinement set" you mean "original set"?
05:20:25 <oklofok> oh alrighty
05:20:45 <oerjan_> well we started with an arbitrary open cover and than used the dimension to refine it
05:20:51 <oklofok> oh indeed we did
05:21:04 <oerjan_> *then
05:21:42 <oerjan_> and then this refined cover pretty directly gives this graph of open vs. closed vertices
05:24:51 <oklofok> but erm so
05:25:35 <oerjan_> ?
05:26:07 <oklofok> take [0, 1] with cover [0, 5), (0.4, 0.6), (0.5, 1], then (0.4, 0.5) and (0.5, 0.6) have intersecting closures even though both are intersection sets
05:26:36 <oerjan_> what's that 5 doing there
05:26:47 <oklofok> haha
05:26:54 <oklofok> [0, 0.5)
05:26:58 <oklofok> 5 was visiting his aunt
05:27:27 <oerjan_> oh hm right
05:27:39 <oerjan_> you only test open sets for touching closed sets
05:27:43 <oerjan_> not other open sets
05:27:45 <coppro> win 16
05:27:53 <oklofok> oh so then it's basically by def
05:28:02 <oklofok> coppro: are these some sorta election thingies
05:28:09 <coppro> oklofok: no
05:28:19 <oklofok> i have no other guesses
05:28:54 <oklofok> common field sizes?
05:29:14 <coppro> no
05:29:40 <oklofok> oerjan_: wait where were we going with this graph thing?
05:29:45 <oklofok> i'm a bit... distracted
05:29:51 <oklofok> i should prepare for this talk thingie
05:29:55 <oklofok> but here i am
05:30:30 <oerjan_> well the graph is just a side thing
05:31:01 <oerjan_> but the thing is, this allows us to partition the whole space into tiny open and closed sets
05:31:22 <oklofok> http://www.math.utu.fi/projects/jac2010/program.html <<< look i'm famous!
05:31:46 <oklofok> it certainly does do that
05:32:14 <oklofok> we had this really fun partition lemma in our seminar on beuhahrug spaces (i may remember the name wrong)
05:32:23 <oerjan_> and if you make them small enough, the measure of any larger open set can be approximated as sums of tiny sets within... but in the limit this forces the measure to be a lebesgue measure.
05:32:42 <oklofok> okay
05:32:46 <oklofok> cool
05:32:50 <oklofok> I GUESS
05:33:07 <oklofok> this was whose def?
05:33:10 <oklofok> i mean
05:33:17 <oklofok> this topological measure thing
05:33:35 <oerjan_> johan aarnes, the advisor of my collaborator alf rustad
05:33:58 <oerjan_> originally he called it quasi-measures
05:34:04 <oklofok> right, guessed it was you ppl's or you wouldn't be the ones doing this basic research on it
05:34:13 <oklofok> or is it called basic research
05:34:21 <oklofok> fundamental essentials research
05:34:22 <oerjan_> pretty much
05:35:47 <oklofok> i used to define a lot of different things (used to meaning it was last months theme) but in the end i just always realize it's a known concept in disguise, so now i just try to take concrete problems others have stated and solve them
05:35:58 <oklofok> month's
05:36:38 <oerjan_> his original example of a quasi-measure was created as a counterexample to a conjecture
05:36:51 <oklofok> of course that only works if you're willing to go far enough that open problems become solvable :D
05:36:59 <oklofok> cool
05:37:16 <oklofok> yeah i guess that's the sensible way to come up with new things
05:37:27 <oklofok> mine is usually more like LET'S TAKE THIS RANDOM THING AND SEE WHAT HAPPENS
05:37:32 <oerjan_> about the linearity of certain functionals on C(X)
05:37:43 <oklofok> okay
05:38:07 <oerjan_> (the measures are equivalent to certain functionals that are almost, but not necessarily quite linear)
05:38:34 <oerjan_> if they _are_ linear then they are lebesgue measures
05:39:03 <oklofok> hmm
05:39:32 <oklofok> i suppose a measure gives you the functional "integral"
05:39:33 <oklofok> ?
05:39:47 <oerjan_> precisely!
05:40:00 <oklofok> how are they not linear
05:40:08 <oklofok> hmm
05:40:28 <oklofok> i know too little about this stuff
05:40:38 <oklofok> MUST
05:40:39 <oklofok> KNOW
05:40:40 <oklofok> EVERYTHING
05:40:53 <oerjan_> http://en.wikipedia.org/wiki/Riesz_representation_theorem#The_representation_theorem_for_linear_functionals_on_Cc.28X.29
05:40:59 <oklofok> obviously i know that
05:41:01 <oklofok> theorem
05:41:07 * oklofok looks
05:41:07 <oerjan_> ok then :)
05:41:19 <oklofok> i know the basic riesz repr theorem
05:41:35 <oklofok> that linear functionals are dot products
05:41:37 <oerjan_> it's that linear <=> lebesgue, in our case
05:41:46 -!- NicolaeDebevec has joined.
05:41:57 <oerjan_> or wait, Borel
05:42:37 <oerjan_> however the "almost but not quite linear"
05:42:50 <oklofok> well i don't know what a "lebesque" measure is, as an adjective
05:42:53 -!- NicolaeDebevec has left (?).
05:43:01 <oklofok> a measure defined on... lebesque sets? :D
05:43:03 <oklofok> well
05:43:12 <oerjan_> yeah i meant borel
05:43:15 <oklofok> yeah
05:43:16 <oklofok> k
05:43:26 <pikhq_> What the fuck?
05:43:37 <pikhq_> In the UK, you have to be over 18 to buy... Plastic cutlery.
05:43:45 <oerjan_> for every function f in C(X), look at the sub-algebra C(f) generated by it. then the functional should be linear on it
05:44:17 * oklofok looks
05:44:30 <oklofok> pretty.
05:44:41 <oerjan_> note that C(X) is _real_ functions. if we were looking at _complex_ functions, then indeed this requirement _would_ force the entire functional to be linear. i think this was an old theorem.
05:45:06 <oerjan_> and the conjecture which aarnes disproved was that this would hold for real C(X) as well
05:45:21 <oerjan_> oh the functional should be positive too
05:45:34 <oerjan_> i think
05:46:12 <oerjan_> the theory _has_ been generalized to signed measures/non-positive functionals too, in fact one of our articles was about it
05:48:07 <oklofok> oh reals okay
05:48:30 <oklofok> my thinking went C... durrr... complex.
05:49:13 <oklofok> you did such cool stuff
05:49:20 <oerjan_> now C here is for continuous i think
05:49:22 <oerjan_> *no
05:49:24 <oklofok> all my theorems are really boring in comparison

05:53:53 <pikhq> Sadly, no.
05:54:04 <pikhq> Halfway there, though!
05:54:07 * oerjan_ assumes pikhq got the reference
05:54:12 <pikhq> Of course.

05:54:27 <oerjan_> true, true

05:56:53 <oklofok> anta?
05:57:16 <pikhq> A more casual form of あなた.
05:57:24 <oklofok> i don't even completely get the sentence :(
05:57:31 <pikhq> "You. Read Freefall."
05:57:33 <oerjan_> UNICODE ATTACK
05:57:33 <oklofok> freefall read "me"
05:57:35 <oklofok> oh lol
05:58:03 <oerjan_> wait oklofok knows japanese?
05:58:05 <pikhq> もっと日本語が欲しいか。
05:58:06 <oklofok> we haven't done any of the short forms
05:58:12 <oklofok> the course is sloooooooow
05:58:16 <pikhq> oerjan_: He's taking a class.
05:58:20 <pikhq> oklofok: I *told* you.
05:58:31 <oklofok> shall is something more japanese
05:58:46 <pikhq> oklofok: Also, not doing the short forms of verbs first is a travesty.
05:58:57 <oklofok> pikhq: told me what? i got the sentence already if that's what you mean
05:59:11 <pikhq> oklofok: I told you not to take a formal class because it would be slow!
05:59:22 <oklofok> pikhq: i think so too, because i see them all the time and i understand nothing outside the class therefore
05:59:24 <oklofok> ah
05:59:50 <pikhq> oklofok: The thing is, the short forms of verbs are the *actual root forms*. The conjugation goes from there.
06:00:03 <oklofok> we just do masu
06:00:12 <pikhq> But nooo, classes insist on teaching the teineigo conjugations.
06:00:14 <oklofok> also we've only done like 70 kanji
06:00:25 <pikhq> (-masu, -desu, etc.)
06:00:31 <oklofok> so i don't even officially know the kanji for "read"
06:00:42 <oklofok> yeah we just do those
06:01:01 <oklofok> and no one fucking ever uses them, at least in the shows i've tried to start watching
06:01:08 <pikhq> See, that's horrifically wrong, and you will have to unlearn things.
06:01:13 <oklofok> :P
06:01:19 <oklofok> well i like a challenge!
06:01:22 <pikhq> The teineigo forms are very commonly used in normal Japanese, but *it's the wrong thing to learn first*.
06:01:46 <pikhq> (shows tend to use more casual Japanese than is otherwise normal, for a variety of reasons.)
06:02:02 <oklofok> alright
06:02:37 <oklofok> even the "quick japanese for business dudes" book does masu only, it just skips telling the basic forms of the verbs! :D
06:02:54 <oklofok> cuz it's faster to just learn masu and not ru + masu!
06:02:57 <pikhq> The worst part is, verb conjugation in Japanese is *really easy* if you start from the plain forms.
06:04:28 <oklofok> well, i'll probably take the second course anyway, it's not like i'll have enough free time next year to actually be able to study it on my own.
06:04:36 <pikhq> But no, they insist on using the teineigo forms first so that you'll be less rude if you somehow find yourself talking to someone in Japanese after 6 months of taking the class.
06:04:52 <pikhq> Even though by that point you'll have trouble saying anything at all because they suck so hard.
06:04:55 <oklofok> hopefully the unlearning i have to do occurs there
06:05:31 <oklofok> i think i could *easily* have a conversation about how good fish tastes.
06:05:38 <oklofok> sakana wa oishii desu yooo
06:06:05 <oklofok> i should learn to write japanese on the computer, maybe.
06:06:27 <pikhq> 魚が美味しいですが、僕にはカレーが一番美味しい事だと思います。
06:06:42 <oklofok> sorry, that's outside my kanjibility
06:07:38 <pikhq> さかなが おいしい ですが、 ぼくには カレーが いちばん おいしい だとおもいます。
06:08:17 <oklofok> fish is good but you find curry the best
06:08:20 <oklofok> i don't get the last word
06:08:25 <oklofok> erm
06:08:26 <pikhq> And, yeah, if you keep up with the classes, you will be permanently illiterate.
06:08:33 <oklofok> the "datoo"
06:08:48 <pikhq> "da to omoimasu".
06:08:59 <oklofok> heh, probably. i'm not keeping up with the classes, i assure you 90% of our class couldn't read taht.
06:09:00 <oklofok> *that
06:09:42 <oklofok> what does "to" mean there
06:09:48 <oklofok> "as well as"? :P
06:10:05 <pikhq> Uh, it's a fairly complex particle.
06:10:16 <oklofok> that much i know...
06:10:27 <pikhq> But the sentence comes out as "Though fish is delicious, I think curry is the most delicious."
06:10:46 <oklofok> yeah
06:10:59 <pikhq> Seriously, you would be significantly better off spending all the time you would have on that class just watching anime without subtitles. *That alone* would be a massive improvement.
06:11:11 <oklofok> :)
06:11:13 <oklofok> yeah possibly
06:11:19 <pikhq> Assuredly.
06:11:24 <oklofok> but i don't find that as entertaining as a monotone lecture
06:12:10 <oklofok> hmm, anime without subtitles might not be such a bad idea, watching it with subtitles isn't doing me much good at least.
06:12:25 <oklofok> because after a few minutes i stop listening
06:12:32 <pikhq> Yeah, the point is to *not* cling to the language you're fluent in...
06:13:13 <oklofok> and still, for some reason i've always used subtitles for learning purposes.
06:13:31 <oklofok> i guess that's intuitive as well
06:13:46 <oklofok> if you're a robot
06:14:29 <oklofok> is "to" always used with omoimasu?
06:14:45 <oklofok> see i just know omoimasu from the dictionary...
06:15:08 <oklofok> i've never actually seen it in a sentence before
06:15:39 <oklofok> and why do you say boku *ni*?
06:15:53 <oklofok> is that also omoimasu's fault?
06:16:00 <pikhq> I'm... Not entirely sure, actually.
06:16:06 <oklofok> :P
06:16:19 <pikhq> The grammar of Japanese has gotten a bit automatic.
06:16:37 <pikhq> The "ni" got added because that conveyed the sense I wanted. Somehow.
06:17:35 <pikhq> It's kinda got a sense of "*But as for myself*, ..." in this context, I guess?
06:17:40 <oklofok> maybe it's a bit like "X ni aimasu", like me as a person
06:17:48 <oklofok> dunno
06:18:10 <oklofok> i just know it's a human postfix thingie
06:18:23 <pikhq> I suggest you just do Japanese often enough that everything happens without thinking about it.
06:18:29 <oklofok> as well as a couple (million) other things
06:18:54 <oklofok> your way is good too.
06:18:57 <pikhq> No, don't. You'll never get good if you do that.
06:19:14 <oklofok> yeah, that was what the restraining order meant
06:19:15 <oklofok> :P
06:19:33 <pikhq> Much like you'll never get good at math by taking elementary/middle school/high school math courses.
06:19:34 <oklofok> well. actually it's not really a good metaphor
06:19:49 <oklofok> true. or even just by taking any courses.
06:20:17 <pikhq> You at least have a *chance* of getting good at math when you study for a math degree.
06:20:28 <oklofok> surely
06:20:47 <oklofok> prolly the highest chance
06:20:50 <oklofok> but still
06:21:14 <pikhq> But below college? "You, too, can learn how to do everything that we have calculators for, but didn't when the curriculum was designed!"
06:21:35 <oklofok> :D
06:21:49 <pikhq> (don't get me wrong, manual calculation is a nice skill and all, but it really doesn't deserve to be a focus of *12 fucking years* of education.)
06:22:11 <oklofok> and done completely wrong, too
06:22:38 <oklofok> well. i guess it's an okay way to teach it to people who don't want to learn it.
06:22:40 <oklofok> but other than that
06:22:45 <pikhq> The pacing on them is absurd.
06:23:58 <pikhq> Arithmetic should *not* take several years to teach.

06:28:47 <coppro> pikhq: May I join you?
06:28:52 <pikhq> coppro: Depends.
06:29:00 <coppro> pikhq: I'm a math major
06:29:12 <pikhq> coppro: What are your thoughts on "improper" vs. "proper" fractions?
06:30:15 <pikhq> Oh, who am I kidding. I know your thoughts on them. "WHY THE FUCK IS THAT A DISTINCTION"
06:30:24 <coppro> pikhq: my thoughts on fractions are: teach pure fractions first. decimal notation etc. can come later
06:31:01 <oklofok> improper/proper fractions is like 4 3/8
06:31:02 <oklofok> ?
06:31:06 <oklofok> vs 7/6
06:31:10 <coppro> yes
06:31:24 <coppro> it is not wrong to draw a distinction
06:31:29 <oklofok> i'm a math major and i totally think that's not a distinction, in most contexts. not this one.
06:31:41 <coppro> it is, however, very very wrong to teach it so heavily like they do
06:31:49 <pikhq> coppro: The worst part is the notation used.
06:31:54 <coppro> especially because the notation is 4 3/8 which later on means 3/2
06:32:02 <pikhq> 2¾ looks to me like 6/4, not 10/4.
06:32:42 <pikhq> Because dammit, that's how it's used anywhere outside of elementary school.
06:34:02 <pikhq> Also strange is the insistence on things like using the LCD for adding/subtracting fractions with different denominators.
06:34:24 <oklofok> prolly, in elementary school, there should be separate classes for set theory, arithmetic, and problem solving
06:34:31 <pikhq> How often is it going to matter that you picked the *smallest* common denominator?
06:34:51 <oklofok> so that math could take 3 times more time slots
06:34:58 <coppro> oklofok: :D
06:35:02 <coppro> also set theory?
06:35:13 <oklofok> set theory is the most important thing in the world
06:35:29 <coppro> yeah, I've just heard lots of suggestions about elementary school education
06:35:32 <coppro> and set theory was never one of them
06:35:37 <coppro> totally agree now that you think of it
06:35:44 <oklofok> we used to have that here, in the 70's or something
06:35:54 <pikhq> coppro: They tried it in the 70s. Problem: it was the same teachers.
06:36:06 <oklofok> the profs think those that was good, because students were not retarded back then, because of that
06:36:08 <pikhq> Y'know, the ones that think that calculus is the highest that math goes.
06:36:19 <coppro> pikhq: oh, I had one of those in high school
06:36:25 <oklofok> unfortunately the ones that didn't become profs, and had normal idiots as teachers, probably didn't have the same idea
06:36:38 <oklofok> okay
06:36:39 <oklofok> what pikhq said.
06:37:45 <oklofok> i wouldn't exactly drop arithmetic out, at least the ppl who aren't going to learn anything interesting anyway learn to count their money :D
06:38:00 <pikhq> Probably the worst part of primary/secondary math education is that it hardly ever touches on something very fundamental to the practice of mathematics.
06:38:02 <pikhq> Logic.
06:38:13 <coppro> +1
06:38:22 <pikhq> oklofok: Yeah, I don't think it should be *omitted*, I just think it's taught far too slowly and they put far too much of a focus on it.
06:38:31 * coppro needs to remember to follow up with the people here who go through math+teaching
06:39:11 <oklofok> coppro: what do you mean "go through"?
06:39:26 <oklofok> (sry i'm slow)
06:39:32 <coppro> oklofok: math+teaching is a program here
06:39:37 <oklofok> ohh
06:39:50 <oklofok> we have something like that too, prolly every uni does
06:40:16 <oklofok> basically if you're good you do pure math, if you suck real bad you become a teacher
06:40:18 <oklofok> :D
06:40:31 <oklofok> i'm not being an ass, it really is like that
06:40:42 <oklofok> based on the ppl i know
06:41:05 <pikhq> The US system has you get a degree in education.
06:41:08 <oklofok> *not just being
06:41:14 <pikhq> Voila, you are magically qualified to teach everything.
06:41:20 <oklofok> hehe
06:41:24 <pikhq> Why? Because fuck making sense.
06:41:42 <coppro> oklofok: Yeah, we have a degree in education too. Except this program is a BMath + BEd program, so the teachers come out knowing nonzero math
06:41:43 <pikhq> (in high school, you *might* start getting teachers with more qualifications. Maybe.)
06:41:44 <oklofok> i had this religious nut as a teacher through 3-6 grade who didn't know anything about anything
06:41:55 <oklofok> except god
06:42:00 <oklofok> she knew a lot of bible stories
06:42:09 <coppro> pikhq: in my experience, it wasn't /quite/ so bad
06:42:12 <coppro> but close
06:43:07 <oklofok> coppro: the teachers have to learn stuff like group theory here too, it's just they pass the relevant courses with bad grades and forget the few things they memorized rote after the course.
06:43:16 <coppro> oklofok: blargh
06:43:36 <coppro> there's also a pure math with teaching option program
06:43:49 <oklofok> what i said there is partly conjecture, have to admit
06:44:00 <coppro> the requirements are actually far looser, but due to the requirement of pure math courses, basically no one goes through with it
06:44:09 <coppro> someone who does probably knows math properly
06:44:15 <oklofok> but anyway, come on, they don't actually need it, the actual facts *will* be useless to them
06:44:30 <oklofok> it's the way of thinking that you'd like them to have
06:44:50 <coppro> yeah
06:44:52 <coppro> more importantly
06:44:55 <coppro> you want them to pass it on

13:25:19 <elliott> Older versions of this license did not have the second sentence with the express warranty disclaimer. This same analysis applies to both versions.
13:25:22 <elliott> heh, gnu have their own ISC license
13:25:25 <elliott> http://www.gnu.org/prep/maintain/html_node/License-Notices-for-Other-Files.html
13:26:15 <oerjan> <Ilari> Seriously, that name containing the ø is pain to type...
13:27:01 <elliott> maybe we'll just replace it with an o, Orjan
13:27:08 <oerjan> although that tl at the end doesn't look particularly norwegian/danish
13:27:11 * elliott gets swiftly banned
13:27:41 <oerjan> i already replaced it with oe, duh
13:29:49 <elliott> oerjan: yeah but oe is actually vaguely accurate :D
13:30:10 <elliott> oerjan: you'll be pleased to know i mentally pronounce your name as "oar-dshjan"
13:30:20 <elliott> where dshj is a combination of dj and sh-n
13:30:36 <elliott> oerjan: or on a good day, oer-JAn
13:30:42 <elliott> where J is hard
13:30:45 <elliott> you know what i mean
13:30:50 <oerjan> i already heard you pronounce it, remember? hm it seems you've deteriorated then
13:31:25 <elliott> oerjan: yeah that was when I had any sort of pretence of being able to get it right
13:32:21 <oerjan> the j should definitely not be an affricate
13:32:27 <fizzie> The backscroll is too long to read, so this might have been mentioned already: but git initially just stores each file into a separate file named after the hash (so identical files are stored only once, but it doesn't use delta-based representation); then every now and then when it deciders to stick all the free-floating objects into a compressed pack file, there it uses both full files and deltas.
13:33:56 <elliott> ais523: wow: " The license is a free software license, incompatible with the GPL. It permits relicensing under a certain class of licenses, those which include all the requirements of the Jabber license. The GPL is not a member of that class, so the Jabber license does not permit relicensing under the GPL. Therefore, it is not compatible."
13:34:09 <elliott> ais523: is that the first license incompatible with the GPL /because it aims to be more compatible/?
13:34:19 <fizzie> (I don't know how it decides which files to store "deltified" and which "undeltified" -- Official Terms from http://www.kernel.org/pub/software/scm/git/docs/technical/pack-format.txt -- or whether it uses the revision-history relationships to look for candidates to deltify.)
13:34:28 <elliott> fizzie: right, it's just scapegoat makes much less sense than git, so it's hard to understand how its storage model applies :D
13:34:44 <elliott> fizzie: considering the whole thing's mostly based on patching patches.
13:35:28 <fizzie> I'm not going to get into your blameable-mammal discussion, it's already too long to jump in; that was just an aside.
13:36:20 <elliott> fizzie: the basic problem is: checking out revisions is Hard when you have to trace N diffs for large N and reassemble the result. But storing multiple copies of the whole tree at periodic points sounds Big(TM).
13:36:40 <elliott> fizzie: so the question was basically "wait, how come linux's git tree isn't very big at all really, but checkouts are still fast?".
13:37:06 <elliott> ais523: clever: [[The reason that this is useful is for the "camp send" command. Rather than, as in darcs, having a separate concept of a "patch bundle", and a separate "camp apply" function to apply them, we can just use the "camp pull" command. We get the interactive patch selection etc for free.]]
13:38:58 <fizzie> Well, the way git decides what to pack and where is "magic": http://www.kernel.org/pub/software/scm/git/docs/technical/pack-heuristics.txt (that's convoluted IRC discussion about it is the official documentation, it seems)
13:40:14 <elliott> fizzie: I've seen this file before...

13:40:56 -!- zzo38 has quit (Quit: Big Brother Is Phishing You.).
13:41:16 <elliott> fizzie: But, summarise it for me: If we have a crazy recursive patch system that takes an awful long time to check out a revision, and we use this to store full copies of (things) at various (points in time), and (possibly compress them), can this give us fast checkouts without huge repositories?
13:42:21 <fizzie> With sufficient magic, I'm sure it can! (Read: I'm still not going to get involved here.)
13:42:39 <elliott> fizzie: BUT IT'S THE BEST VCS /EVER/
13:43:26 <fizzie> Yes, I'll be sure to try it out after you have made it.
13:43:56 <elliott> fizzie: Are you *sure* you want to commit to that?
13:44:20 <elliott> fizzie: You'll have directory trees cluttered up with +scapegoat! Can you even *talk* to a man who would name a directory entry that?
13:44:40 <elliott> And really, immutable functional weenie storage -- do you trust people like that?
13:44:49 <fizzie> What, not going with Gregor's not-in-anyone's-font-ever GOAT? Well, still.
13:45:18 <oerjan> if mutation was good enough for darwin...
13:45:41 <elliott> fizzie: Can you TRUST a program that, when discussed about, was so hopelessly generic that the command "sg give-me-a-reasonable-cwd" was discussed?!
13:45:42 <fizzie> Well, I would like my weenie to be safe...

15:27:22 <ais523> is that the most recent, or should I clog?
15:28:14 <elliott> ais523: well, there's more before that
15:28:25 <ais523> I know, I saw everything before
15:28:28 <elliott> ah
15:28:31 <ais523> I was just showing the last oen
15:28:32 <ais523> *one
15:30:27 <elliott> ais523: Any replies re: empty directory on first change; camp?
15:30:33 <elliott> (Two questions.)
15:31:39 <ais523> I'd say the repo doesn't, platonically, exist at all until there's something in it
15:31:52 <elliott> ais523: well, yes, but I mean what "sg init" creates
15:32:07 <elliott> ais523: obviously, it needs 1 patch in there, that everything else is based on, right?
15:32:27 <ais523> hmm, I think so, yes
15:33:09 <ais523> but checking the directories is how you determine if two repos are currently the same project or not, effectively
15:33:17 <ais523> you can split them apart and join them, but that's an explicit change to the arrangement
15:33:27 <ais523> so, if you didn't have any changes at all, how would you know where to commit?
15:33:37 <ais523> thus, we need to decide whether the repo's created by sg init or sg commit
15:33:48 <ais523> the second would be perverse, but has a certain logic to it
15:33:58 <ais523> (in which case, sg init would just set the metadata ready for a repo to be created)
15:36:42 <elliott> ais523: well, one could argue that, if you need 1 god patch to base everything on, there's no reason it can't be the first
15:36:53 <elliott> you can't say "but you need a patch to base patches on!" and then say that 1 patch doesn't need to be based on any
15:38:14 <ais523> directories don't need to be based on anything
15:38:28 <ais523> although you can't merge them together without adding a relationship between them and some other directory
15:38:33 <elliott> ais523: sure they do; patches don't have an "insert X", they just have "append X after Y"
15:38:38 <elliott> so you need an Empty Directory to base things on
15:38:45 <elliott> with... one item
15:38:46 <elliott> inexplicably
15:38:49 <ais523> no, no items
15:38:58 <ais523> "insert new empty file in Z" only requires a directory to insert it in
15:39:00 <elliott> ais523: then how do you add an item?
15:39:07 <elliott> ais523: ok, consider a file with 0 lines
15:39:09 <elliott> how do you append a line?
15:39:46 <ais523> "add 'x' between start of file added by 5, and end of file added by 5"
15:40:13 <ais523> giving BOF and EOF their own hashes would probably make the actual storage a little simpler
15:40:31 <ais523> but the point is just what they're added between, which is the start and end of the empty file
15:40:54 <elliott> fair enough
15:40:59 <elliott> ais523: what about the fact that directories are unordered?
15:41:03 <elliott> you can't have "add X between"
15:41:54 <ais523> you just have "add X into"
15:42:02 <ais523> the "between" is only important for preserving order
15:42:08 <ais523> if you don't care about preserving order, you just give the parent
15:42:33 <ais523> e.g. if you have a directory containing files called a.txt and d.txt, you don't want to conflict on adding b.txt just because someone else added c.txt
15:42:38 <ais523> nor would there be any sensible reason to do so
15:43:00 <ais523> so directories have different operations from files because they're inherently different structures
15:43:21 <ais523> (likewise, if you were versioning, say, a key-value store, you'd have "add into", "change", "delete" because order doesn't matter)

16:59:40 <Vorpal> hah at the topic
17:03:17 <Vorpal> ¬confused → ¬understood, And it is well known that being confused about something means you don't understand it. Thus ¬understood → confused. Which means ¬confused → confused.

17:05:04 <Vorpal> if we are confused, then we might have understood it. And since I feel this is pretty confusing, I'd say that confused is true. However, I can't from that conclude I understood it since we have an implication at hand (not an equivalence)

17:08:18 <Vorpal> (iirc you got it working some time ago?)
17:08:19 <oerjan> um no
17:08:29 <Vorpal> oerjan, was \exists
17:09:09 <oerjan> my font includes little outside latin scripts
17:09:19 <Vorpal> oerjan, oh. Tried dejavu?
17:09:43 <oerjan> i haven't tried anything
17:13:52 <elliott> <Vorpal> ¬confused → ¬understood, And it is well known that being confused about something means you don't understand it. Thus ¬understood → confused. Which means ¬confused → confused.
17:13:57 <elliott> Vorpal: wow you're like a master of formal logic
17:14:27 <Vorpal> elliott, stop being sarcastic
17:14:40 <elliott> okay. wait, let me reconsider. no.
17:14:41 <Vorpal> elliott, it was of course not serious meant
17:15:33 <Vorpal> elliott, the whole "And it is well known that being confused about something means you don't understand it" bit is obviously bogus (using confused in another, though related, sense)
17:15:34 <oerjan> Vorpal: it doesn't look like it supports windows...
17:15:44 <elliott> oerjan: it's just a ttf.
17:15:47 <Vorpal> oerjan, ... what? it is just a true type font
17:15:59 <elliott> and people use it on windows
17:16:03 <oerjan> i know very little about fonts
17:16:15 <oerjan> i just didn't see any mention of windows on the page
17:16:18 <elliott> oerjan: http://sourceforge.net/projects/dejavu/files/dejavu/2.32/dejavu-fonts-ttf-2.32.zip
17:16:19 <elliott> :p
17:16:21 <Vorpal> hm. not sure that symbol is from it. It looks badly hinted
17:16:30 <elliott> drag contents to Control Panel -> Fonts
17:16:37 <Vorpal> the system might be picking it from elsewhere
17:17:47 * oerjan is suspicious that the mono is sans serif only...
17:18:22 <elliott> oerjan: it is.
17:19:12 <elliott> oerjan: Luxi Mono I think has decent unicode support, and is serif'd
17:19:26 <elliott> it's in http://xorg.freedesktop.org/releases/individual/font/font-bh-ttf-1.0.2.tar.bz2
17:19:37 <elliott> the luxim* files
17:19:47 -!- ais523 has joined.
17:19:54 <elliott> i have no idea how much unicode it does, though
17:19:54 <elliott> hi ais523
17:19:55 <oerjan> hm maybe i'll try that instead
17:20:09 <Vorpal> elliott, unless he has extremely high res screen, then serif isn't very good on screen
17:20:29 <oerjan> i'm already used to serif, is all
17:20:31 <elliott> Vorpal: that is incorrect.
17:20:33 <ais523> hi elliott
17:20:44 <elliott> and i don't think telling oerjan "your opinions are wrong!" is productive at all
17:20:55 <ais523> elliott: *most systems render serif in an ugly way?
17:21:06 <ais523> I have seen serif rendered well on screen, but it's rare
17:21:07 <Vorpal> elliott, oh, you mean he use a line printer for irc?
17:21:17 <elliott> ais523: you use terrible settings, though
17:21:23 <elliott> ais523: (and so do most people/OSes)
17:21:35 <ais523> elliott: well, this OS renders much better than most of the others I use
17:21:45 <ais523> worst is probably Adobe Reader on CentOS
17:21:54 <ais523> which manages to screw up kerning incredibly badly
17:22:06 <ais523> it's as if any given pair of letters is kerned at random
17:22:17 <elliott> enough about this, let's talk about everyone's favourite subject -- scapegoat!
17:22:24 <elliott> (EVERYONE'S)
17:22:44 <Vorpal> hm wouldn't a normal res screen, but larger, brighter, and further away, give pretty much the same result as a high res screen?
17:23:10 <elliott> no, your eyes have faeries in them and would blind you if you tried to do that.
17:23:29 <ais523> Vorpal: obviously no, it has a lower bandwidth
17:23:37 <ais523> (assuming that it has the same refresh rate)
17:24:06 <Vorpal> ais523, ... wait, you mean for the GPU<->display connection?
17:24:09 <ais523> (note: applying communications theory to font rendering doesn't normally work, but it can at least prove the most egregious statements wrong instantly)
17:24:15 <ais523> Vorpal: no, for the screen<->eyes connection
17:24:44 <Vorpal> ais523, hm. Lower bandwidth how?
17:24:55 <ais523> there's just less information being sent
17:25:27 <ais523> e.g. the pixels are coarser, so the shapes of the letters aren't as defined, and that has nothing to do with the brightness of the screen
17:25:58 <ais523> hmm, I assumed that by "normal res" and "larger" you meant, say, "1024x768, but on a larger monitor"
17:26:07 <Vorpal> ais523, err, did I say res? I meant dpi
17:26:08 <ais523> I suppose "resolution" is ambiguous in this context
17:26:17 <oerjan> elliott: should i copy the entire archive to Fonts, or just the contents of the ttf/ directory?
17:26:27 <elliott> oerjan: just the .ttf files.
17:26:53 <elliott> oerjan: you *may* need to extract the archive to a normal directory first, but dragging is worth a try.
17:27:49 <Vorpal> ais523, so if it scales so the size in your field of view is the same, and the size of each pixel is the same, then you just need to take care of light level (since the light is not unidirectional). Maybe focusing distance would cause an issue
17:27:56 <Vorpal> which is what I was wondering about
17:28:09 <Vorpal> s/cause an issue/be an issue/
17:31:25 <oerjan> gah this looks horrible
17:32:44 <oerjan> and also i'm suspicious that putty didn't say anything about it containing any chinese or japanese characters, in fact the list of scripts was precisely the same as for courier new
17:32:56 <Vorpal> elliott, does windows try to use other fonts if it can't find anything in the current font for a given codepoint?
17:33:19 <elliott> Vorpal: no it just puts a little picture of adolf hitler there
17:33:29 <Vorpal> elliott, ....
17:33:30 <elliott> oerjan: i didn't actually check if it has jewnicode :D
17:33:32 <oerjan> Vorpal: windows might i don't know, but putty certainly doesn't
17:33:40 <elliott> (adolf hitler hates jewnicode, that's why he replaces the glyph)
17:33:43 <oerjan> elliott: er...
17:33:51 <elliott> oerjan: by jewnice i mean unicode.
17:33:54 <elliott> *jewnicode
17:33:58 <elliott> it's actually a jew plot.
17:34:00 <Vorpal> oerjan, I suspect elliott is sleep-deprived
17:34:02 <oerjan> i understood that
17:34:07 <oerjan> Vorpal: well so am i
17:34:09 <elliott> oerjan: just trying to help out
17:34:44 <elliott> oerjan: UBUNTU EVERY SONG OF THE DOVE IS IXED
17:34:46 <elliott> FXIED
17:35:27 <Vorpal> oerjan, anyway, *if* windows or putty tries to find the symbol in other fonts, then dejavu sans has \exists
17:36:15 <elliott> Vorpal: oh yeah cuz substituting a non-mono character in mono text is just a great idea
17:36:49 <Vorpal> elliott, let me check mono too
17:37:12 <Vorpal> elliott, mono has it too
17:37:16 <Vorpal> elliott, so your point is moot
17:37:28 <oerjan> Vorpal: putty doesn't even try to substitute the CJK characters that i do have in other mono fonts
17:37:36 <Vorpal> huh
17:37:47 <oerjan> it seems to use the selected font, only
17:37:49 <Vorpal> oerjan, but shouldn't this be handled by the system text rendering API?
17:37:58 <Vorpal> and happen transparently to the application
17:38:00 <elliott> oerjan: if you answer, Vorpal will start ranting about your OS.
17:38:22 <oerjan> elliott: i suspect putty more than windows on this point
17:38:24 <Vorpal> elliott, look, on linux it happens in cairo or fontconfig or something. It is just as messy
17:38:32 <elliott> that won't stop you :)
17:38:37 <oerjan> maybe i should actually upgrade putty, it's probably from 2006
17:38:40 <elliott> oerjan: why not just use a windows irc client... i mean it's just an idea :P
17:38:51 <Vorpal> elliott, I could rant about the linux implementation too

17:39:59 <Vorpal> elliott, I'm not sure where text rendering should happen. On one hand, there is a good case for not putting it in the display server. On the other hand, having it everywhere is a messy solution too
17:40:12 <elliott> Vorpal: shouldn't it just be a library.
17:40:20 <oerjan> Vorpal: also e.g. IE _does_ substitute when i look at the logs e.g., but the mononess is ruined
17:40:22 <elliott> "servers" are basically useless
17:40:33 <Vorpal> elliott, so what will elliotOS do?
17:40:35 <Vorpal> tt*
17:40:43 <elliott> whenever you see a server in linux, it's usually a library that does privileged stuff but that is called from user code
17:40:46 <elliott> which unix can't handle
17:40:48 <elliott> so it has to be a server
17:40:56 <elliott> server as in X server not httpd
17:42:49 <Vorpal> elliott, where will elliott OS do font rendering?
17:43:36 <elliott> Vorpal: in your heart

17:47:56 <Vorpal> elliott, I found no "way way less than" sadly
17:53:16 <Vorpal> elliott, btw you said that substituting non-monospace for monospace missing codepoint is bad. Yes indeed. But is it worse than not being able to show the information?
17:54:12 <elliott> information is in your mind

19:00:45 <Vorpal> elliott, ever used nexttoward() ?
19:01:05 <Vorpal> (or nextafter)
19:01:38 <elliott> Vorpal: Nope.
19:01:41 <elliott> Vorpal: I don't touch math.h generally.
19:01:56 <elliott> Especially floats.
19:01:56 <Vorpal> elliott, seems python has no mapping for nextafter() hm
19:02:02 <elliott> Floats make me cry.
19:02:10 <Vorpal> elliott, these are for double
19:02:11 <Vorpal> not float
19:02:17 <elliott> Ah.
19:02:24 <elliott> Can't you write it in Python, given the double epsilon?
19:02:50 <Vorpal> elliott, well, presumably I could. The trick is figuring out said epsilon
19:04:27 -!- cheater99 has quit (Ping timeout: 245 seconds).
19:04:30 <Vorpal> elliott, OR I could just create a binding with cython :D
19:04:44 <elliott> Vorpal: While x>0 { y=x; x/=2 }; return y
19:05:28 <elliott> Vorpal: wait, does python even have doubles?
19:05:36 <Vorpal> elliott, float in python is double
19:05:44 <Vorpal> elliott, it doesn't have single precision float
19:05:49 <elliott> Vorpal: oh right double is float
19:05:53 <elliott> I thought double was fixed-point there
19:06:32 <Vorpal> what?
19:06:50 <Vorpal> elliott, how do you use the epsilon now again to figure out how far it is to the next point, since the actual distance between the points you can represent will vary over the range
19:07:14 <Quadrescence> I MEAN 754
19:07:16 <elliott> Quadrescence: THAT'S NICE TO KNOW
19:07:18 <elliott> WHY ARE YOU TELLING US
19:07:25 <Quadrescence> sounded relevant
19:07:34 <Vorpal> it doesn't does it? 1.0/0.0 is not inf
19:07:37 <elliott> <Vorpal> elliott, how do you use the epsilon now again to figure out how far it is to the next point, since the actual distance between the points you can represent will vary over the range
19:07:39 <elliott> i was assuming fixed-point
19:07:43 <Vorpal> elliott, ah
19:07:46 <Vorpal> elliott, well, it isn't
19:08:49 <Vorpal> elliott, besides fixed point would be highly inconvenient for this thing, since I need to work both with small number (0.00284 or so say) and huge numbers (10^40 or that range)
19:09:01 <Vorpal> or even larger

19:20:47 <fizzie> "You are at the mercy of the underlying machine architecture (and C or Java implementation) for the accepted range and handling of overflow." So the spec (2.6, 2.7, 3.1 all have the same text) doesn't exactly guarantee IEEE-754, but it might often be.
19:20:50 <fizzie> (Throwing an exception at 1.0/0.0 is perfectly valid, in fact one of the optional alternatives in the standard; though I guess for full compliance there should be some way of disabling it, and that -- the fpectl module -- is not built by default, it seems.)

19:44:58 <elliott> But he's not an idiot :P
19:45:20 <Phantom_Hoover> Oh, so those "spoof" interviews when he admits C++ was an evil plot were actually true?
19:45:37 <elliott> Phantom_Hoover: Pretty much! (Actually it's more like: he's a decent guy who had a really, really terrible idea and still hasn't realised that yet.)
19:46:16 <Phantom_Hoover> Remind me again of the well-articulated reasons C++ sucks/
19:46:51 <elliott> Phantom_Hoover: Ow ow ow ow ow ow pain ow.
19:47:05 <elliott> Phantom_Hoover: When parsing your language is Turing-complete, it's time to find a new language.
19:47:07 <Phantom_Hoover> *Well*-articulated.
19:47:17 <Phantom_Hoover> elliott, oh, operator overloading?
19:47:33 <elliott> Phantom_Hoover: Nope.
19:47:34 <Phantom_Hoover> Or templates?
19:47:35 <elliott> Phantom_Hoover: Templates.
19:47:38 <elliott> Phantom_Hoover: Because of <>
19:47:38 <Phantom_Hoover> Ah.
19:47:43 <elliott> < can be either less than or open template.
19:47:47 <elliott> Well, okay, that's just context-sensitivity.

19:49:42 <Vorpal> s ironic (which seems patently obvious), it says something about modern landline telephones...
19:49:54 <Vorpal> the second one seems more idiotic
19:50:08 <Phantom_Hoover> That is because ESR is fractally wrong.
19:50:25 <Phantom_Hoover> His whole worldview is wrong, and if you zoom in on any part of that worldview, it's still wrong.

21:11:27 <olsner> iirc, in PHP's case the original author(s) have freely admitted not having a clue
21:11:54 <coppro> Gregor: $_ is no longer implicit in Perl 6
21:12:08 <coppro> though it can be accessed through the alternative name ""

21:17:26 <olsner> elliott: hmm... I wonder how they managed to break Java :/
21:17:28 <elliott> + is addition, / means "over" (fold, like foldr in Haskell)

21:26:04 <elliott> thought so
21:26:15 <elliott> Phantom_Hoover: try running from outside bin :P

21:28:30 <elliott> Vorpal: Um, or use update-alternatives.
21:28:32 <Vorpal> elliott, why, openjdk works fine with minecraft
21:28:33 <elliott> You're not meant to change those yourself.
21:28:37 <elliott> And because OpenJDK clearly doesn't work with J.
21:28:54 <Vorpal> elliott, true, but checking /etc/alternatives != changing it there
21:29:03 <Vorpal> elliott, checking is good for finding out WHERE it goes
21:29:14 <Phantom_Hoover> elliott, how do I change it?
21:29:18 <Vorpal> elliott, so my statement was correct
21:29:21 <elliott> Phantom_Hoover: Try removing *openjdk* :P
21:29:25 <elliott> Vorpal: update-alternatives can show that.
21:29:31 <elliott> Phantom_Hoover: As in sudo aptitude purge *openjdk*
21:29:31 <Vorpal> elliott, not as fast
21:29:40 <Vorpal> elliott, it involves reading help output first
21:29:46 <Vorpal> compared to ls -l
21:30:23 <Phantom_Hoover> elliott, I'm assuming that glob is metaphorical.
21:30:33 <elliott> Phantom_Hoover: nope
21:31:16 <Phantom_Hoover> elliott, "Couldn't find any package blah blah blah "*openjdk*""
21:31:29 <elliott> aptitude search openjdk
21:31:30 <augur> wheres alice been? :(
21:31:33 <elliott> remove all "i"s
21:31:35 <elliott> augur: right here!

21:31:43 <elliott> augur: i'm ehird :P
21:31:48 <augur> o man wat
21:31:52 <elliott> you... didn't realise this?
21:31:56 <augur> firstly, i thought you had one l and one t
21:31:59 <elliott> yeah i had a sex change!
21:32:01 <elliott> i'm a MAN now
21:32:16 <augur> second, no, i thought you were some random kid named elliott
21:32:21 <elliott> well, i am
21:32:24 <elliott> some random kid named elliott :P
21:32:34 <augur> oh man, ive been hostile towards you for no reason :(
21:32:39 <elliott> :D
21:32:42 <elliott> good to know i'm that dislikeable
21:32:43 <Vorpal> awesome
21:32:44 * augur hugs elliott
21:32:50 <Vorpal> elliott, indeed you are!
21:32:55 <augur> now go die in a fire
21:33:03 <elliott> 10.10.26:16:54:28 <augur> elliott: what

21:33:03 <elliott> 10.11.12:02:30:37 <augur> elliott: what
21:33:03 <elliott> 10.11.26:16:40:15 <augur> elliott: you're talkative

21:33:04 <elliott> 10.11.28:14:47:16 <augur> elliott is agreeing with me on something
21:33:05 <elliott> 10.12.01:19:58:24 <augur> elliott: deny
21:33:07 <elliott> 10.12.06:12:04:29 <augur> elliott: but thats because performance is not competence
21:33:09 <elliott> augur: man, so hostile
21:33:13 <augur> knowing you're ehird, now i HAVE a reason
21:33:36 <augur> i ended up not getting those you know
21:33:54 <augur> i got a pair of sony's
21:34:03 <augur> still bluetooth, but not jaybirds
21:34:14 <elliott> better than radio-based wireless ones at least
21:34:20 <augur> what?
21:34:25 <elliott> those ones have constant fuzz and if you don't play audio for too long -- I'm not joking here --
21:34:26 <augur> the jaybirds were bluetooth too..
21:34:27 <elliott> they go to white noise
21:34:28 <elliott> LOUD white noise
21:34:30 <augur> oic
21:34:32 <elliott> augur: oh, i was just commenting in general
21:34:34 <augur> mine are fine
21:34:36 <Phantom_Hoover> elliott, more errors!
21:34:37 <augur> sound great
21:34:38 <elliott> seriously, you just sit there... haven't played music in a while
21:34:39 <elliott> FZZZZZZZZZZZZZZT
21:34:41 <elliott> Phantom_Hoover: what now
21:34:53 <augur> elliott: i missed you :(
21:34:56 <Phantom_Hoover> There's a POPUP
21:35:01 <elliott> Phantom_Hoover: yes, that's the introduction.
21:35:08 <Phantom_Hoover> In hideous Java blue.
21:35:08 <augur> ironic, since you were here the whole time
21:35:14 <elliott> Phantom_Hoover: you can change that.
21:35:22 <Phantom_Hoover> Saying "Load library file:bin/libjnative.so failed."
21:35:24 <Vorpal> elliott, how can you live with wireless headphones?
21:35:30 <elliott> Phantom_Hoover: wait, is your system actually 64-bit?
21:35:31 <Vorpal> elliott, they are laggy
21:35:32 <elliott> Vorpal: i don't any more :P
21:35:37 <Vorpal> elliott, stuff doesn't sync up
21:35:40 <elliott> ...although lag was not my complaint, what?
21:35:43 <Vorpal> elliott, at least in my experience
21:35:44 <Phantom_Hoover> elliott, as opposed to?
21:35:46 <elliott> the radio ones are fine with lag
21:35:49 <elliott> just terrible at everything else
21:35:53 <elliott> Phantom_Hoover: um, as opposed to 32-bit linux
21:35:54 <Phantom_Hoover> Not really being very 64-bit?
21:35:56 <Vorpal> elliott, I'm talking of video sound being out of sync with the bluetooth ones I tried
21:36:05 <Phantom_Hoover> Being 53 bit but not telling anyone?
21:36:05 <elliott> Phantom_Hoover: uname -r
21:36:07 <elliott> does it end with x86_64?
21:36:09 <elliott> erm
21:36:11 <elliott> *amd64
21:36:15 <Vorpal> elliott, compared to plain cable ones
21:36:24 <Phantom_Hoover> 2.6.32-5-amd64
21:36:26 <Phantom_Hoover> Yes, it is 64-bit.
21:36:26 <Vorpal> elliott, which work fine, don't need battery, and give better sound
21:36:30 <elliott> Phantom_Hoover: huh.
21:36:32 <elliott> Vorpal: yeah yeah
21:36:49 <Vorpal> elliott, beat my DT150 with wireless. Good luck
21:36:59 <Phantom_Hoover> FWIW, the FSF have some mysterious marker on java -version, so I am SUSPICIOUS
21:37:00 <Vorpal> elliott, sb live + DT150 that is
21:37:09 <elliott> Vorpal: i don't use wireless.

21:37:20 <elliott> how did that happen.
21:37:59 <elliott> awesome, java doesn't do font fallback
21:38:00 <elliott> like a boss
21:38:32 <elliott> or maybe it does
21:38:41 <elliott> nope
21:38:56 <augur> elliott: monads!
21:38:56 <augur> :D
21:39:14 <elliott> "Users can add a physical font as a fallback font to logical fonts used in Java 2D rendering by installing it in the lib/fonts/fallback directory within the JRE."

21:51:37 <pikhq> (note: if you can replace fontconfig with something less XML-loving and make it universal, I will love you forever)
21:53:37 <Phantom_Hoover> elliott, comment in the context of @.
21:53:58 <elliott> Phantom_Hoover: @ has no configuration.
21:54:01 <Phantom_Hoover> FWIW, I will Leave And Never Come Back if you don't declare that XML is banned from @.
21:54:04 <elliott> It renders fonts in the perfect way, as determined by me, God.
21:54:16 <elliott> Phantom_Hoover: Well, it'll have an XML parser... for feed reading, say :P
21:54:47 <Phantom_Hoover> elliott, can't you configure it by messing around with the rendering code?
21:55:04 <elliott> Phantom_Hoover: NO. It is protected.
21:55:10 <pikhq> Phantom_Hoover: By the same notion, everything is configurable because we have text editors.
21:55:20 <elliott> INDEED
21:55:47 <Phantom_Hoover> pikhq, yes, but in @ everything is adjustable at runtime.
21:55:50 <Phantom_Hoover> Somehow.
21:57:14 <pikhq> MAGIC
21:58:09 <Phantom_Hoover> elliott, wait, what happens when you meddle with code that's being executed?
21:58:28 <elliott> Phantom_Hoover: Your bunny turns into a fluff.
21:58:34 <elliott> That is as cute as it sounds, too.
21:58:55 <elliott> Phantom_Hoover: More realistically: It works.
21:59:00 <Phantom_Hoover> elliott, indeed, but what happens to the computer/
21:59:11 <Phantom_Hoover> How?
21:59:39 <pikhq> Mmmm, milkshake...
22:00:26 <elliott> Phantom_Hoover: Well, if you edit an executing function, nothing will happen, but the next time it's called...
22:00:39 <Phantom_Hoover> elliott, hmm.
22:00:40 <Vorpal> elliott, Deewiant: down?
22:00:52 <Deewiant> Quite.
22:00:59 <elliott> Phantom_Hoover: If you want to change a tight-looping function while it executes, use the debugger.
22:01:12 <Phantom_Hoover> elliott, ah.
22:01:25 <elliott> i.e. hit pause/break or some similar key, step a few times if you want to, and tell it to change the code, then exit the debugger and continue.
22:01:29 <Phantom_Hoover> So you still need to restart your web browser if significant changes are made to the code?
22:01:42 <elliott> Not really; I would imagine a web browser is composed of a good many functions.
22:02:03 <elliott> If the main loop was compiled to be non-recursive (looping instead) and you modified that, then maybe. But I'd like to see if I can't make it update the code in that case too.
22:02:11 <Phantom_Hoover> Yes, but presumably some of them are going to run for a very long time.
22:02:26 <elliott> Well, there's no actual main loop; FRP.
22:02:28 <Phantom_Hoover> Anything that waits for user input, for instance.
22:02:32 <elliott> Everything is just event --> reaction in the simplest case.
22:02:35 <elliott> Phantom_Hoover: Asynchronous.
22:02:46 <elliott> Indeed, your browser won't even hard-loop like that, since it's based on an event-based GUI toolkit.
22:02:56 <elliott> It's just that in @, /everything/ is asynchronous and you use FRP to do all effects.
22:04:38 <Phantom_Hoover> I DO NOT KNOW THESE WORDS
22:04:51 <elliott> Phantom_Hoover: What, "asynchronous"?
22:05:03 <Phantom_Hoover> FRP!
22:05:08 <Phantom_Hoover> Hard-loop!
22:05:15 <Phantom_Hoover> Event-based!
22:05:18 <Phantom_Hoover> Effects!
22:05:21 <elliott> Phantom_Hoover: Hard-loop = loop :P
22:05:29 <elliott> Your browser, when it pops up a dialogue box, doesn't freeze.
22:05:36 <elliott> Because it's not in a loop; it's doing everything normally.
22:05:46 <elliott> It just has an event set up for "dialogue-box-clicked-OK".
22:07:25 <fizzie> Re earlier topic, Bluetooth wireless headphones + Linux was indeed a really very laggy combination; but the same headphones were markedly better (lag-wise) in some other systems. Maybe the others do some sort of lag-compensating guesswork, who knows.
22:11:50 <elliott> Does anyone have a tool to merge two fonts?
22:12:04 <elliott> i.e. A+B => C where if char c not in A, char c in C, taken from B
22:12:09 <elliott> but otherwise char c in C, taken from A
22:13:56 <fizzie> FontForge might be capable of that, but the user interface (if you can call it that) is so confusing, no-one can tell.

22:22:38 <Vorpal> fizzie, that made a difference
22:22:38 <calamari> can you extend a class to allow fallbacks?

22:24:39 <elliott> calamari: it's not OSS, so no.
22:24:57 <calamari> has anyone else noticed that linux audio has really gotten lame in the past year or so, skipping and etc? I wonder if something happened to the driver for my card
22:25:31 <calamari> maybe it goes back more than a year now, I lose track of time
22:25:55 <calamari> seemed to start around the same time as that pulseaudio stuff, but that could just be a coincidence
22:26:07 <elliott> it isn't
22:26:10 <elliott> pulseaudio is the worst.
22:26:46 <calamari> but pulseaudio isn't in the kernel, right?
22:27:42 <calamari> I was assuming if I selected ALSA, then I avoided pulseaudio messing me up
22:28:20 <elliott> calamari: not unless you uninstall pulseaudio
22:28:30 <elliott> calamari: it reroutes ALSA's library to go to pulseaudio, which then goes to ALSA
22:28:41 <calamari> ah, I see
22:28:42 <elliott> calamari: note: if you're on ubuntu, uninstalling pulseaudio = no volume control
22:29:12 <calamari> and I'm also not sure if KDE 3.5's audio stuff is screwing me too
22:29:46 <calamari> since they had added yet another layer of crap lol
22:30:05 <calamari> elliott: not even alsamixer?
22:30:23 <elliott> calamari: Well, sure, that will work.
22:30:31 <calamari> ahh ok
22:30:31 <elliott> calamari: You're using KDE 3.5 still?
22:30:38 <calamari> yeah
22:30:51 <elliott> calamari: Don't; use Trinity.

22:31:04 <elliott> http://trinity.pearsoncomputing.net/
22:31:08 <calamari> FUCKING AWESOME!!!!
22:31:57 <calamari> oh maybe it just changed names, lets see
22:32:22 <elliott> calamari: hm?
22:32:25 <elliott> what changed names
22:32:32 <calamari> nope, this seems different
22:32:55 <elliott> calamari: what did you think changed names?
22:32:57 <calamari> I was using this before deb http://ppa.launchpad.net/kde3-maintainers/ppa/ubuntu lucid main
22:33:23 <calamari> oh wait, there it is
22:33:36 <calamari> okay so I'm using the same one
22:34:01 <elliott> you're still on lucid? :-P
22:34:05 <calamari> yeah
22:35:28 <calamari> I used to upgrade right away, but I got tired of stuff breaking so now I upgrade a release behind
22:35:51 <olsner> upgrade to something that's already old: FUN
22:36:43 <calamari> elliott: do you use kde 3.5?
22:37:25 <calamari> err Trinity
22:38:12 <elliott> calamari: nope, I use gnome :P
22:38:29 <elliott> calamari: more out of convenience than anything else
22:38:50 <calamari> yeah I put gnome onmy new work lptop because I do realize kde 3.5 is crufty
22:39:02 <calamari> and it seems alright
22:39:23 <calamari> maybe they removed all the features they could for a while and it stabilized
22:40:53 <calamari> the earlier KDE always reminded me of some kind of Windows 3.1/95 mix.. however the later KDE was better looking at they never removed features.. instead they just scrapped the entire thing and put ot KDE 4 lol
22:41:32 <calamari> I only went to KDE3 because I was afraid of what Gnome would remove next.. there was one release where you couldn't even edit the menus
22:44:08 <calamari> to be fair, though, the menu stuff was more of an outside standards effort that they adopted.. but they definitely could have waited a bit on that one
22:45:35 <elliott> who cares about linux anyway
22:45:36 <elliott> or X11
22:45:39 <elliott> or... uh
22:45:40 <elliott> keyboards
22:45:47 <pikhq> Nobody actually likes X11 any more.
22:46:44 <Vorpal> pikhq, I bet there is some freak that does
22:47:02 <calamari> lol if I had to choose between keyboard and mouse, the rodent would lose out
22:48:52 <calamari> you don't use xman exclusively due to it's amazing ui? oh wait, neither do I

23:24:16 <elliott> tswett: Go on, then :P
23:24:23 <elliott> augur: it's a racket
23:24:54 <augur> elliott: racket?
23:24:55 <elliott> OK, seriously, someone merge two TTFs for me.
23:24:57 <elliott> Infinite praise.
23:25:00 <elliott> augur: A swindle, no less.
23:25:08 <tswett> Oh, fine. :P
23:25:13 <augur> elliott: wat :|
23:25:30 <tswett> Let's consider a list, like [1,7,2,5,3,8,9,4,2,7,3]. Then you just...
23:25:36 <elliott> fizzie: tswett: Also, it only counts if you use a predefined "avg" function.
23:25:41 <elliott> That you can substitute for any function.
23:25:43 <elliott> To make moving.
23:26:20 <Vorpal> elliott, down?
23:26:22 <tswett> map (avg . take 4) . tails $ [1,7,2,5,3,8,9,4,2,7,3]
23:26:51 <Mathnerd314> what's a good size for an interpreter of a "minimal" language?
23:26:56 <elliott> Mathnerd314: um, in what? bytes?
23:26:58 <elliott> what language?
23:27:06 <fizzie> elliott: Okay: mean(buffer(v, 4, 3)). (Except you can't quite substitute "any" function there; but most do it right by default.)
23:27:27 <tswett> Funnily enough, that will take the average of [1,7,2,5], then of [7,2,5,3], . . ., then of [4,2,7,3], then of [2,7,3], then of [7,3], then of [3], then of [], at which point the program will crash.
23:27:27 <Mathnerd314> elliott: a Lisp, implemented in anything, counting tokens
23:27:32 <elliott> fizzie: Cheater :P
23:27:38 <elliott> Mathnerd314: counting tokens? pg got to you eh?
23:28:01 <elliott> Mathnerd314: Anyway it's a meaningless question without specifying the implementation language.
23:28:02 <Mathnerd314> elliott: yeah; you can count LOC if you'd rather
23:28:03 <elliott> tswett: Now fix it :P
23:28:22 <Mathnerd314> elliott: you can use any language you want.
23:28:42 <Mathnerd314> elliott: I just want an order-of-magnitude estimate
23:28:48 <elliott> Mathnerd314: then the question is meaningless :)
23:29:07 <fizzie> buffer(v, 4, 3) gives [[0; 0; 0; v(1)] [0; 0; v(1); v(2)] [0; v(1); v(2); v(3)] [v(1); v(2); v(3); v(4)] ... ], and most functions that make sense for a vector do their operation separately for each column.
23:29:47 <Mathnerd314> elliott: ok, we'll start with c. what size is a C interpreter for Lisp
23:30:03 <Mathnerd314> ?
23:30:06 <elliott> tswett: BTW:
23:30:08 <elliott> 4 (+/%#)\ 1 7 2 5 3 8 9 4 2 7 3
23:30:08 <elliott> 3.75 4.25 4.5 6.25 6 5.75 5.5 4
23:30:10 <elliott> tswett: Good luck beating that.
23:30:16 <elliott> Mathnerd314: Uh, 100-200 lines? C is pretty verbose.
23:30:34 <elliott> tswett: That includes the avg function.
23:31:50 <Mathnerd314> elliott: so 700 lines of Haskell is way too long?
23:31:54 <fizzie> octave:6> sum(buffer([1 7 2 5 3 8 9 4 2 7 3], 4, 3, 'nodelay'))/4
23:31:54 <fizzie> ans =
23:31:54 <fizzie> 3.7500 4.2500 4.5000 6.2500 6.0000 5.7500 5.5000 4.0000 3.0000
23:32:04 <fizzie> I guess it's a bit longer. And repeats the window width thrice.
23:32:08 <elliott> Mathnerd314: definitely. if the language is minimal in even the slightest, definitely.
23:32:10 <elliott> even if it isn't
23:32:16 <elliott> 700 lines of haskell could control nukes :)
23:32:21 <elliott> fizzie: Psht.
23:32:27 <Deewiant> Nuke controllers aren't that complicated.
23:32:30 <elliott> Deewiant: Shaddap.
23:32:36 <elliott> fizzie: OK, now define a function that takes a window size and a list and moving-averages them.
23:32:54 <elliott> fizzie: mavg=:(+/%#)\
23:33:16 <elliott> tswett: You too. :p
23:33:38 <fizzie> "f = @(w, v) mean(buffer(v, w, w-1, 'nodelay'))" if you don't mind using mean.
23:33:45 <fizzie> s/f/mavg/ if you like.
23:34:13 <fizzie> The 'nodelay' is a bit debatable; it zero-pads in front if you don't include that, but according to someone's definition that might be the right thing.
23:35:06 <elliott> fizzie: OK, now write a function that produces a screwy TABLE OF AVERAGES OR SOMETHING, like so: http://sprunge.us/MThf
23:35:13 <elliott> The last column is the moving averages, the first is the list itself; not sure what the list inbetween is.
23:35:27 <tswett> map negate
23:35:32 <tswett> A nuke controller in Haskell.
23:35:37 <elliott> fizzie: Oh, it's each window size from 1 (just return the list directly) to the size you specify.
23:35:43 <tswett> Requires a relatively "smart" API.
23:35:45 <elliott> fizzie: With the moving averages for each window being a column.
23:36:19 <fizzie> Stop being like that, it's going to be pretty ugly.
23:36:23 <elliott> The 3D version does nothing interesting, unfortunately. :P
23:36:29 <elliott> fizzie: That's okay, I like ugly!
23:36:37 <elliott> fizzie: At least it'll teach people not to call J ugly. :P
23:37:33 <elliott> "mmavg is (add over divide length) infix infix", what's so hard about that!
23:37:42 <elliott> (When each element is pronounced :P)
23:38:42 <elliott> fizzie: SO HOW'S IT GOING
23:41:43 <fizzie> http://p.zem.fi/gp4u I HOPE YOU'RE HAPPY NOW.
23:41:51 <fizzie> It's not identical due to lack of nodelay.
23:42:04 <elliott> fizzie: Does yours handle >1D arrays?
23:42:24 <fizzie> Probably not. It almost didn't handle window width of 1 either.
23:43:41 <fizzie> I don't think buffer deals with matrices sensibly, you'd have to do something else, probably another arrayfun over a list to do the buffering.
23:43:45 <fizzie> I'm not going to try that.
23:44:01 <fizzie> MATLAB's pretty horrible when you just want to map.
23:44:17 <fizzie> At least Mathematica has that funky /@ operator or whatever they called it.
