colomon it certainly is a pain when it happens when you don't want it to.
[Coke] I'm trying to construct lists of lists, and I just keep ending up with a single list ofelements. 00:33

TimToady it's been low hanging fruit for a month or two now
colomon has anyone implemented it? I don't see spectests in roast...
grondilu TimToady: does anyone plan on implementing it? 00:41
TimToady colomon: that's what NYI usually means :P
grondilu needs it for its rosalind stuff
colomon Rakudo as well as Niecza.
grondilu s/its/his/
colomon grondilu: use List::Utils, it is implemented there (I think)
grondilu oh, ok.
colomon as a sub, not a method. 00:42
TimToady hates any module with the name "Utils", too much like "Misc"
diakopter Code
Engine
Library
[Coke] updates gist.github.com/coke/5541613
grondilu anyway there should not be a List::Utils module in a programming language that is supposed to be functional.
diakopter GrabBag 00:43
colomon TimToady: I didn't think List::RoutinesThatIThinkShouldBeInCoreButTimToadyHasntAgreedYet would fly as a name. 00:44
TimToady doesn't see anything wrong with that one :)
00:44 cooper- left, cooper- joined, cooper- is now known as cooper
colomon Though I actually added combinations there after it was already spec, hoping to get feedback on the implementation. Never did. 00:45
TimToady by and large, I'd rather universally useful routines end up in core rather than in modules; worst case: "use Math;"
if it ends up bloating, we can always load them lazily
grondilu colomon: why didn't you put it in core directly? One implementation is always better than no implementation.
TimToady mislikes computer languages that don't think math is fundamental 00:49
grondilu yeah, that's one thing I like about perl6: lots of standard math stuff are in core, not in modules. 00:51
colomon grondilu: never wrote a combinations routine before. was hoping for feedback before adding it to one of the implementation's cores. that's all. 00:52
TimToady any combinations routine is better than none :)
grondilu there is a simple implementation in rosettacode anyway
TimToady especially if it lets us start writing tests 00:53
colomon TimToady: spoken like someone who hasn't seen all the crap code I've written in the last 31 years.
TimToady "I weep for you," the Walrus said, "I deeply sympathize."
colomon also, there are tests, in List::Utils, of course. ;) 00:54

as far as lazyness is concerned, I guess we could force it with a gather take, couldn't we? 01:43

01:43 japhb_ left
TimToady not sure, given how it returns partial results 01:43
grondilu I don't know then. 01:44
TimToady thinks that if it's a bad idea, gather/take is poorly optimized
same for dynamic variables in general, oughta be able to cache things locally within a CALLER or two to keep things fast
grondilu I suggest we mention these concerns in the RosettaCode entry, so that if someone has a good idea, he can write it there. 01:45

FROGGS has a holiday too
moritz too, unsurprisingly
FROGGS :o)

raiph good * 07:38
FROGGS hi raiph 07:39
diakopter hi. 07:41
FROGGS \o 07:42
moritz mysql takes 9 minutes to create an index, and 8 to drop it again 07:59
FROGGS moritz: irclog database? 08:00
lizmat MYISAM?
FROGGS how big (filesize) is that thing?
tadzik diakopter: *poke* 08:01
lizmat if I remember correctly, an index in MyISAM is part of the table itself, so creating or dropping an index, is effectively a rebuild
moritz FROGGS: yes; about 0.6GB 08:02
lizmat that's why the drop is shorter than the create, because the resulting file is smaller
it's pure i/o bound
moritz lizmat: ah, so it create a complete copy of the database
lizmat table
moritz erm, yes
lizmat a database is a directory
moritz in this case, the database has only one table :-)
lizmat a table is N files in that directory
FROGGS 0.6GB?? wow, that is not much 08:03
lizmat why are you using MyISAM anyway, wouldn't InnoDB be better ?
moritz hysterical raisins
lizmat table would become 2x as big on disk
moritz but since I have nearly no concurrent writes, and no foreign keys, there's not much reason to switch to InnoDB 08:04
lizmat but you wouldn't have to wait for reading when doing inserts
moritz but I plan to migrate to postgres anway
lizmat ok, so it's one table for all channels ?
moritz yes
lizmat seems like having one table / channel would at least save you the "channel id" column everywhere 08:05
if this is in one table because of searching, then please don't use MySQL for searching
but create an elastic search backend or so
moritz but it would make listing of all channels much harder in a cross-DB fashion 08:06
lizmat but anyway, you were going to migrate to PostgreSQL
moritz lizmat: the plan is to use apache lucy for fulltext search
lizmat cool
moritz (the successor of KinoSearch)
I have a branch which does that, but it's not yet ready for usage
lizmat sounds like a plan to me
08:10 Ulti joined, cognominal joined
moritz mysql really annoys me 08:11
I have the query SELECT DISTINCT(day) FROM irclog WHERE channel = '#perl6' ORDER BY day 08:12
and it uses the index on irclog(day, channel)
so far so good
I change the query to
SELECT DISTINCT(day) FROM irclog WHERE channel = '#perl6' AND nick <> '' ORDER BY day;
and create an index on irclog(day, channel, nick)
and the select doesn't use it
but rather uses only the index on irclog(channel), and a temporary table from there on 08:13
lizmat is scratching her head to try to remember why that is
it's been well over a year since I was deep into MySQL 08:14
there is a command that will tell you how MySQL optimizes a query 08:15
tadzik explain?
lizmat yup, that's the one 08:16
so what does EXPLAIN SELECT DISTINCT(day)…. say?
dev.mysql.com/doc/refman/5.0/en/exp...utput.html for an explanation of that output 08:18

moritz oh, that one was missing the group by 08:25
dag_ moritz: Create an index on irclog(channel, nick, day)
Oh, and use PostgreSQL instead ;-)
moritz dag_: I tried that first
it didn't use that index 08:26
arnsholt Does ordering of the columns matter?
dag_ arnsholt: Yes.
moritz: Are you sure you created the index with the columns in the order I gave?
moritz if you do an index (foo, bar), it'll build a tree optimized for first search foo, then bar 08:27
arnsholt Ah, right
moritz dag_: I've tried both day first and day last; I kinda hope the order of the other two doesn't matter match, because the query is commutative
but I can try again, just to be sure 08:28
moritz waits for another 9 or 10 minutes
dag_ moritz: In my experience the first column in the index should be included in the WHERE clause in the query.
Ulti moritz: try giving an index hint 08:29
also this is why I hate mysql
FROGGS moritz: if you remember the discussion from yesterday, I believe Foo.WHO is not connected to $*PACKAGE.WHO I do when building the ast
jnthn class Foo { ...when you're compiling this, $*PACKAGE in the compiler is Foo } 08:30

Ulti moritz: dev.mysql.com/doc/refman/5.1/en/index-hints.html try giving a hint for the order by 08:32
I've never had index hints actually work for me though :S

dag_ moritz: You'll never look back :-)
moritz I already use it for new projects
Ulti I used postgres for my dayjob about 9 years ago, it was better than the latest mysql I use today
FROGGS jnthn: right
moritz Ulti: I'm curious, do you have experience with replication with postgres? 08:34
Ulti nope, only in mysql 08:35
dag_ moritz: I have
FROGGS jnthn: I have something like: module Foo { our @a; my @b; say Foo:WHO<$test> } # and putting something in ($*PACKAGE.WHO)<$test> in the our decl, and printing its content within the my decl 08:36
jnthn: but at runtime (Foo.Who)<$test> is (Any)
(Foo:WHO<$test> was a typo here in irc)
dag_ moritz: It is quite easy to set up, and works like a charm. Do you have any particular questions regarding PG replication? 08:37
jnthn FROGGS: Can I see the patch?
FROGGS hmmm, quiet messy
jnthn: just look at line 20 and 80 :o) gist.github.com/FROGGS/a30afd1fef1d2a742a96 08:39
moritz dag_: just if it works in practise, and if there is monitoring for it 08:40
FROGGS jnthn: so within the my-block it prints 7, and I would export to get that at runtime too (or at least a warning that this is not a p6opaque) 08:41
jnthn nqp::say( $?PACKAGE ); 08:42
Did you mean $*PACKAGE there?
FROGGS maybe, yeah
jnthn ($*PACKAGE.WHO){$name} := make $past; # that is a huge confusion of object space and AST 08:43
dag_ moritz: Yes, it works really well. The only real snag I've run into is that directories for tablespaces aren't automatically created on the slave(s). Simple solution: Use only the default tablespace (doesn't matter with recent disk systems, anyway)
FROGGS jnthn: true, recognized it after doing that :o)
jnthn It's $cont that needs to go in there.
moritz dag_: ok, thanks
FROGGS jnthn: that is the command I run: make install && perl6 -e 'package Foo { { our @x; say @x }; my $y; say (Foo.WHO)<$hurz> }' 08:44
jnthn yeah but
($?PACKAGE.WHO)<$hurz> := 7;
You've installed the thing in Perl6::Actions::<$hurz>
FROGGS -.-
feels a bit stupid 08:45
jnthn Should be $*PACKAGE
FROGGS my previous line is missing /action
cool, thanks so far
jnthn: and I can bind $cont directly to ($*PACKAGE.WHO){$name}? I have to do something like around line 75, right? 08:46
reading in #perl isn't healthy most times 08:48
last question was about your mentioned object space <> ast

jnthn moritz: Too much. Like, < 80s to ~100s. o.O 09:21
moritz not glacial, but easy to measure :-)
jnthn Yes. 09:22
Well, well enough that I should hunt it down.
labster Sounds like ~200s on my machine.
tadzik heh, +1
labster jnthn: can you (or someone) add constants for STAT_UID, STAT_GID, and STAT_ISLNK to vm/parrot/QAST/Operations.nqp? Looks like it's already on the Java side.
I've been looking at OS.pm, trying to track down places I could get rid of pir references -- and mostly just getting lost in the code. But that one looks easily replaced. 09:26

nwc10 jnthn: when you say "working (modulo running spectests) Rakduo" do you mean Rakudo on Parrot, but using the same NQP as will do the JVM? 09:34
FROGGS moritz: didn't you say that this is invalid? github.com/perl6/roast/blob/master.../our.t#L53 09:36
jnthn nwc10: Rakudo on Parrot, after one of the refactors to make things portable.
FROGGS r: package Foo { { our $x = 7 }; { say $x } } # valid or invalid? 09:38
camelia rakudo fe7049: OUTPUT«7␤»
nwc10 I take it that Perl6LexInfo/Perl6LexPad are PMCs written in C? 09:40
FROGGS I think so too 09:41
jnthn nwc10: Yeah.
nwc10: And they did a lot of stuff that was a real pain for porting.
nwc10 oh, gosh
09:41 berekuk left
FROGGS jnthn: after you made rakudo portable too, do you think one can port nqp/rakudo to Go in a reasonable timeframe? 09:42
jnthn FROGGS: I think you'd need to work out how to solve the module loading and eval like stuff first. 09:44
FROGGS hmmm, I see 09:45
nwc10 Go compiles to native code, doesn't it? Rather than to a VM? 09:46
arnsholt Yeah, that's gonna be tricky
nwc10 well, it sort of means that it's going to be the same pair of problematic answers for any language that compiles to native code (and possibly the same answer) 09:47
arnsholt A native code generating Perl 6 compiler would be awesome, of course
jnthn Right.
nwc10 and a third problem question answer of "Garbage Collection?" if the language you wanted to target doesn't have it
IIRC C++ somewhere in the future is talking about GC
FROGGS Go has a GC afaik
arnsholt Go is GCed
nwc10 yes, afaik Go does. And commented that on a 32 bit system that inevitably means that your integers can often look like pointers 09:48
jnthn It's best to figure out how to solve the Really Hard Project-Killer problem early, rather than in the middle of things :)
nwc10 so, Go and C++-with-a-GC are roughly the same problem, aren't they?
and Rust
arnsholt Go is always statically linked. That's another important difference 09:49
nwc10 oh. that's going to be fun
arnsholt Yup
nwc10 in which case, it's not clear whether it will be possible to port to Go in any reasonable timeframe 09:51
and whether it's going to be that *useful* to do so
what does Go give you, as a target "machine"? Seems, really, only a garbage collector 09:52
FROGGS well, the only reason for doing it at all is performance
nwc10 you have to implement module loading (for ahead of time compiled modules) and eval all by yourself.
FROGGS yeah, havn't thought of that :/ 09:53
nwc10 nor had I.
jnthn Well, managed to get from 100s to 88s.
FROGGS \o/
jnthn That's "better" 09:54
FROGGS jnthn: can you do that on my machine too?
:o)
jnthn As in, still slower than before but not ridiculously.
nwc10 you didn't tell us what the previous speed was :-)
jnthn nwc10: 80s or so
nwc10 as far as I can see, you just said "<80s"
jnthn nwc10: It was around 79s or so
nwc10 aha, OK, so it's about 10% slower.
jnthn Yeah. I'm not *that* worried in so far as I've now hidden something that used to be spread all over Rakudo behind an interface. 09:55
nwc10 yes, to me that sounds like a fair trade
jnthn The speedup I just got was from implementing the thing behind it a little better.
I'm pretty sure that with more effort, we can go one better again.
oh noes, test fails 09:56
arnsholt How do you decide where to optimise in cases like this, BTW?
Do you just meditate on the source, or use some kind of profiling tool?
jnthn arnsholt: Well, in this case I knew what I'd changed so it was largely a case of putting changes in one by one to understand which one was most guilty. 09:57
arnsholt That makes sense 10:01
FROGGS well, I think it is a bit like with chuck norris: the code does what jnthn++ wants 10:05

also: somebody suggested ANALYZE TABLE. am not sure anymore whether that works for MyISAM or not
what you want to prevent, is getting "using filesort" in the "Extra" column 11:00

lizmat in any case, I would probably create a lookup table for channel name -> SMALLINT translation, and then use a SMALLINT for channel 11:03
I assume the channel is now a VARCHAR(31) or so? 11:04
moritz yes
several times I've been pretty close to redesigning the whole thing 11:07
with separate tables for networks, channels and actual log lines 11:08
tadzik masak: makes sense, thanks :)
moritz but, so far it worked just fine
lizmat if it suddenly became slower, it is usually because it runs out of RAM for TEMP tables 11:11
and then has to go to disk, which is ~ 2K times slower
moritz it became slower because I changed the query :-) 11:12
lizmat if it goes to disk, then it is slow, and basically unusable for any interactive environment
moritz UTF-8 test for the logs: ø
lizmat wrt to "channel", are you really expecting UTF-8 characters in there? 11:13
moritz no
lizmat then by disallowing UTF-8, you would reduce the size of the VARCHAR by a factor of 3
because MySQL saves space for the "worst" case 11:14
having it as an index, makes it worse :-)
moritz does a VARCHAR really allocate all the space it could possibly need?
lizmat yup, that's why it says "93" for keylen in the first EXPLAIN output 3 x 31 11:15
moritz anyway, I'm working on migrating to postgresql 11:16
lizmat dev.mysql.com/doc/refman/5.0/en/cha...olumn.html 11:17
would be a simple ALTER TABLE that will reduce the size of the table by 7M * 62 bytes

gtodd masak: would you like me to add links to the solutions on each of the workshop pages ? e.g. [Solutions](gist.github.com/masak/5496294#oneliner) on github.com/masak/workshop/edit/mas...NELINER.md
jnthn has a bunch of changes in this chunk of code in this branch so only half appreciates the changes :P
This looks much correcter than what we had before, though.
FROGGS my patch passes the spectests (with the earlier mentioned corrections), and now I'll go through the ~12 rt tickets about our-things 14:33
jnthn Yeah 14:34
FROGGS is the name $*W.install_lexical_container bad for our-vars? I didnt want to duplicate it because my and our shared too much
jnthn I think it's fine, and certainly better than what we've got. I'll just have to re-work a chunk of it.
14:35 benabik joined
jnthn 'cus I changed install_lexical_container a lot. 14:35
FROGGS k
jnthn Yeah, it's not the best name for it...
I would have preferred to have an install_package_container and factor out the commonalities into a third method.
But that can come later, I guess. 14:36
FROGGS k, I'll think about proper names after rt-tickets
jnthn Doing more changes like that will just make the merge conflicts we'll get even more of a pain to fix.
FROGGS hmmm, true
jnthn Alternatively, just do the patch right off in the jvm-support branch ;) 14:37
FROGGS meh
I need it for v5
jnthn ah
FROGGS almost every test file (~480 files) starts with: BEGIN { @INC = qw(../lib) } 14:38
masak gtodd: I dunno; adding solutions to the exercise pages feels wrong to me. 14:41
gtodd: I'm fully OK with associating them somehow with the workshop -- but putting them in the path of people who haven't written their own solutions yet feels somehow... weird.
gtodd masak:right ... 14:44
maybe put a link somewhere but not on the problem page itself !

colomon grondilu: what do you mean? number of decimals it has? number of decimals that will be printed? Something else? 16:42
arnsholt grondilu: Why do you need to know? 16:44
Remember that the number of decimals in an expansion depends on the base, and might not be finite 16:45
grondilu example: 3.141 should give 3
so I mean base 10
arnsholt And the same Rat might have an infinite amount of decimals in one base, but not in another
colomon grondilu: what should 1/7 give? 16:46
grondilu oh, I mean litteral decimal
so it's not from a rational, it's from a decimal.
colomon decimal string? 16:47

grondilu yeah 16:47

grondilu 1/7 is not a decimal
arnsholt grondilu: There's nothing built-in to get that (and I don't think there should be), but it shouldn't be too hard to extract 16:48
Hmm. Or it might actually be a bit tricky to compute
PerlJam grondilu: if it's a literal, how come you don't know how many decimals places you typed in?
arnsholt But again, what do you need this for?
grondilu PerlJam: I get it from stdin
16:49 berekuk joined
grondilu (and I don't chose it) 16:49
PerlJam oh, so it's a string
16:49 Pleiades` left 16:50 jeffreykegler joined
arnsholt Oh, if it's from stdin, I'd probably just m/^^ [\d+] \. (\d+) $$/ and get the length of $1 16:50
PerlJam assuming "good" data, find the length of the string, find the position of the decimal, subtract :)
grondilu I need to do this because I must compare a number to an other one, and consider them equals if the difference is below the precision of the first one.
example: compare 128.0586 and 128.05858. The difference 0.00002. That's below the precision of the first one, thus the number are considered equals. 16:52
see? 16:53
arnsholt Right. I'd probably go with the regex solution
grondilu had wished for a more elegant way
16:54 Pleiades` joined
colomon greatly doubt there is a more elegant way 16:55
16:55 gdey joined
grondilu wonders if there should not be a Decimal class inheriting from Rat 16:55

colomon grondilu: why?! 16:56
benabik If 3.1000 == 3.001, I'd be surprised.

colomon grondilu: do I really have to specify 3.019999 to say it's 3.02 to six places? 16:57

masak daxim is not here. I'm trying to follow his advice at irclog.perlgeek.de/perl6/2013-05-02#i_7009867 looking for nice real-world problems on StackOverflow. so far I've learned that ikegami++ and (brian d foy)++ write really nice answers to Perl questions, but I haven't found any good material to base exercises on. 17:45
am I searching stackoverflow in the wrong way?
is there a way to search stackoverflow that brings out a lot of nice real-world problems solvable in Perl? 17:46
daxim writes "mostly mundane of course, but also sometimes illustrative of program design, pick from them instead". what I'm finding is not even mundane, but questions such as "why is there only one '=' in '<=>'" or "why does Perl have a reputation as a write-only language". 17:47
17:47 jaldhar left, domidumont left
FROGGS well, I dont know stackoverflow well, but usually ppl tend to describing a single problem, not their project 17:49
so I dont know if his advice is actually a good one
masak I don't feel I'm finding bits that are big enough, or cohesive enough, to use in a workshop. 17:50
and I'm wondering if it's because of the way I search, or because of the actual questions on there.
FROGGS ya, it might be easier to ask the ppl here what they usually do at work, and abstract reoccouring bits
general db-access could be such a candidate 17:51
moritz one thing that comes up on perlmonks regularly is reading two files, and then joining them on a column 17:52
or sometimes on two columns
masak ooh.
that might even be a good one for the non-beginner track.
masak adds an issue
moritz++
moritz or filtering out lines from one file if a certain column exits in the second file
there are many variations
masak aye. 17:53
moritz another one that comes up pretty often is extracting stuff from web pages
masak well, I do have a SCRAPER exercise.
thinking of extending it somewhat, though.

moritz rakudo's looks correct.
17:58 sqirrel joined
masak oh, indeed, it should warn, and I guess print nothing. 17:58
colomon The use of uninitialized value message definitely should be appearing.
but why print nothing?
jnthn FROGGS: How many RTs does it fix? :) 17:59
masak colomon: because an undefined value stringifies to nothing?
FROGGS jnthn: 6, but some of them are duplicates 18:00
colomon masak: does it? is that spec?
masak $ perl -we 'print my $x, "\n"'
Use of uninitialized value $x in print at -e line 1.
(and no more output)
colomon: if there isn't spec, I invoke "everything unspec'd works like in Perl 5" :)
colomon S02: "Type objects sometimes stringify to their name in parens, to indicate undefinedness. " 18:01
"sometimes" is gloriously vague there.
and masak, wouldn't the p6 equivalent of your p5 code there actually call .gist, which definitely does not return an empty string. 18:02
colomon does not really care what the answer to this question is, he just wants an answer so he can implement it.
FROGGS hmmm, I would expect that say gives (Int), yeah 18:03

FROGGS jnthn: I take the silence as "yes" :P
TimToady it's supposed to repeatedly pull out mod 256 for the 'Just another Perl hacker'
[Coke] wonders if all the .gist/.Str differences are documented for each type.
TimToady it gets the first 8 characters correct, so...
it's obviously something on a 64-bit boundary 18:06
colomon TimToady: oooo, that was my Just another Perl hacker from masakism. Except I hardcoded it in base something-or-other rather than base 256.
TimToady thinks modmap (or whatever we decide to call it) would be a useful addition to the language 18:07
colomon TimToady: wait, how do you figure that? Rakudo's answers above are clearly insane....
TimToady hmm, actually, it's the *last* 8 characters that are correct 18:08

cognominal in nqp what are the respective purposes of $past.symbol(…) and QAST::Var.new() which are sometimes used for the same variable ? 23:06
jnthn .symbol is a place for the compiler to stash any info it wants to keep around about a symbol.
It's just a hash of hashes really 23:07
cognominal my hunch is that QAST::Var.new create the variable and, $past.symbol makes it visible to the generated perl code

jnthn The .symbol is really just used as a handy place for the compiler to keep notes about a symbol as it does its work

jnthn But that's mostly a "fallback" thing; Rakudo always knows the scope of things so it tends to be explicit. 23:10

labster raiph keeps posting my blog on reddit. In retrospect, the "How to start hacking on Rakudo Perl 6" was kind of a misleading title ... 23:13
jnthn sleep, 'night o/ 23:17
raiph well, your blog isn't part of planetsix, i suspect few p6 watchers have switched to planeteria, they are great blogs, and the title made sense to me...
o/ jnthn
labster oh it makes sense inside the community, but everyone outside was like "oh, I can do random hacking *with* P6? Cool." 23:18
Well, thanks. I certainly wasn't expecting to get a 1100 hits on a post for how to hack a compiler. But if we get one or two of them to do it... totally worth it. 23:20
FROGGS gnight jnthn
labster The goal is to try to recruit people smarter than myself :o)
raiph do you have solid evidence that lots of folk are interpreting it the unintended way? 23:22
labster No, just that the page is getting twice as many visits. Hey, I'm not complaining or anything.
raiph heh 23:23
i'm trying to choose very carefully what i post to /r/programming

cognominal I suppose that if there has been forums discussing the first HLL compilers versus good macro assemblers we would have the same kind of discussions. People showing stuff that's fast in assembler and cannot even be done on HLL and dissing compilers. 23:41
I mean at the time of the very first compilers.
TimToady well, there were forums, they just weren't electronic :)
cognominal so they are hardly accessible from google, I suppose. 23:42
FROGGS so they dont exist
cognominal by today standards, if it is not accessible from google they don't exist indeed and have never existed :) 23:43
TimToady so, does Perl Monks still not exist? 23:45
last I knew, they didn't :)

.oO(Look at the power and flexibility of my 8086 asm example! When's that going to happen in C?)
cognominal: that's a generous definition of existence. It's close to at most the bottom of fifth page of results (assuming a well-formed search query) 23:46
cognominal TimToady, well I think Perl need to be more web aware. perlmonks marks perl as hold hat. TimToady, Is it true that Tim O'Reilly proposed a chapter on the web in programming Perl and you answered you did not want to pigeon hole Perl ? 23:47
That's easy to criticize... with hindsight. 23:48
TimToady I'm certain that we had many reasons for most of the decisions we made, including whether it would fit 23:50
and whether there was already going to be other books for that 23:51
cognominal cannot sleep and goes back to study nqp internals 23:53
flussence the problem with putting anything about web development into print is that it's outdated before you finish typing...
cognominal at that time, it was not so big and did not move so fast. 23:54

cognominal speaking of W3C standards, I heard that chome was dropping mathml as part of his choice of forking the graphic layer 23:56

lue Apparently, HTML 5.0 is supposed to be a recommendation in 2014 (which surprised me, because the last time I read anything was the fuzzy exclamation that it would take "decades" for HTML5 to be approved) 23:57
