moritz miso2217_: thanks for the effort, but that's really a contrived example. Any real-world application of this would involve splitting on a comma 06:47
miso2217_: contrived examples are easy to find - it's real-world examples that I'm after 06:48
06:48 Su-Shee_ is now known as Su-Shee
moritz miso2217_: also minimal quantifiers (*?, +? etc.) are special-cased in that they do a certain amount of backtracking even inside :ratchet (otherwise they would always match the minimum count, and be fairly useless), so they don't make a good example 06:49

07:12 MUILTFN left 07:18 Mowah left 07:28 domidumont joined
moritz how's the course? 07:37
07:46 satyavvd left 07:54 awoodland joined
masak promising so far. 08:02
the concepts are very language-agnostic, so I'm hoping to be able to apply these things to my Perl 6 coding as well. 08:04
08:04 awoodland left
moritz what's the topic? 08:05
masak the whole course is about DDD and CQRS. today we're talking about bounded contexts and aggregates. 08:08
both are devilishly simple concepts, but they apply to everything else in the course, so it's important to understand them well. 08:09
things are a bit 'emperor's new clothes'-y sometimes, in that things sound like bland advice of the type "make sure you separate concepts that don't belong together". but on the other hand, when you go out into the Real World and look at business code, that's exactly what people tend not to do. 08:10
moritz the point is teaching good techniques to do in practice what you preach 08:12
masak aye.
what's positive about DDD and CQRS is that getting the language right is actually a big part of it. so a Perl person like me fits right in. :) 08:13
moritz never heard those two abbreviations before
masak I hadn't either, until I started my new job in January. 08:14
best way I can describe it is this: for a long time I thought if I just understood Patterns, I'd level up from just a general understanding of OO and architecture. 08:15
but patterns aren't really the next level. Domain-Driven Design is.
moritz what do you mean by "Patterns"? sounds like an overloaded term to me 08:16
moritz really shouldn't distract masak++ from his course 08:18
masak I mean Design Patterns, as in the Gang of Four book.
it's ok, we're having a break now.
moritz oh, I never "believed" in them
given that in Perl, some of them are just two lines or so 08:19
masak they have some valid points. but they're simply that, patterns.
moritz I always wondered why they made such a big fuzz
masak and yes, some patterns in some languages go away in other languages.
others, like Interpreter, are important even in Perl 6. I believe both PGE and nqp-rx use Interpreter. 08:20
masak </pause> 08:22
08:24 satyavvd joined
miso2217 moritz: I can't think about any real world example where backtracking would be needed beside performance. I'll try to find some ideas on google. 08:26
moritz miso2217: I think that the example of the word substring duplication is a good one, it just needs to brought into a shape where the backtracking actually works 08:30
erm, is needed
08:30 shi left
mathw I read an interesting thing once which said that you can consider design patterns to be patches for missing features in your programming language 08:30
moritz something like anchoring it, and adding a .* to the front or so
mathw This is why some of them are trivial in some languages, because that's a language which already has that feature
moritz mathw: I guess that's true to a certain extent 08:31
mathw yeah to a certaine xtent
I wouldn't say it applies to all patterns
moritz mathw: other design patterns are simply formalized experience from solving a certain class of problems
mathw And I do tend to think they're overrated in general
I've got a colleague who thinks the Visitor Pattern is absolutely awesome
Whereas I think it exposes all the things that are pooey about virtual method calls 08:32
And his justification for it being awesome seems to stop somewhere around 'but it's in the book!'
Khisanth anything that is in a book is awesome? 08:33
moritz :-)
mathw: you should write a different book, and point to that :-)
08:39 noganex left, noganex joined
mathw moritz: maybe I will 08:51
'mathw's little book of programming' 08:52
08:52 awoodland joined
moritz mathw's non-bullshit book of non-bullshit programming 08:52
mathw that's a better title 08:53
I like that
it would need to have code fragments in C++, Perl 5, Perl 6 and Haskell at least
moritz
.oO( Anti-Patterns Observed From Anti-Programmers )
 08:54
that would be a different book though
08:54 dakkar joined
Su-Shee peter norvig has written a nice article about how 16 of the 24 DP are obsolete in Lisp. 08:55
moritz sounds like fun :-)
arnsholt Su-Shee: I have a friend who rants about DP all being work-arounds for not having proper lambdas =) 09:01
tadzik DP? 09:02
moritz Design Patterns
tadzik oh, 16 of the 24, I see 09:03
misread that
Su-Shee I'm also very hm not critical but let's say suspicious of design pattern (most of them, at least). So I read critiques carefully. 09:04
mathw arnsholt: a lot of crappy programming structure is down to a lack of lambdas IMO
arnsholt There's that as well 09:05
That's probably the thing that annoys me the most when working in Java. I can't use lambdas and everything that comes with it
map and grep for example
Su-Shee "Ruby Design Pattern" is very nice because it shows how to break several of them in a nice, rubyish way. (which basically applies to perl 5&6 as well.)
mathw arnsholt: annoys me in C++ as well. I really need a new compiler which supports C++0x lambdas. 09:06
moritz arnsholt: what really annoys me is the design bloat in libraries of languages that don't have closures
or no pointers to routines at all
arnsholt Yeah, that's annoying as well. Java can do closures with anonymous inner classes, but it's a bit of a hack 09:07
moritz you can't just install a callback, you need to implement the MyCallbackableForSpecificPurpose interface
and instantiate an object
and then pass that around
arnsholt Indeed 09:09
mathw yeah 09:10
and C++ makes you define an entire class for a functor (until C++0x, anyway)
I suspect I will use STL algorithms a lot more when I can define the functor in place
moritz it's a bit curious that the STL relies on callbacks, and it's from a language that doesn't necessarily make them easy 09:14
(yet) 09:15
mathw yeah it seemed like the library design begged for a language feature which wasn't implemented yet
std::for_each is a real pain to use without lambdas 09:16

woosley hello *, perl6 09:16
what dose key word augment in class definition mean?
moritz woosley: it means "add to an existing class" 09:17
tadzik that you're to modify an existing class, rather than creating new
moritz dictionary.reference.com/browse/augment
miso2217 I would like to write the perl6 highlighting definition file for kate/kwrite/KDevelop. Any ideas on this? Is there a way to use STD.pm for this to generate part of the highlighting definitions automatically or do I need to go tho all manual way? May be here is a way to reuse the existing vim definition file? 09:18
woosley moritz: LoL, looks like you know that my native language is no english
09:19 donri left
moritz woosley: not mine either :-) 09:19
TiMBuS hey moritz, did you end up rakudobugging that thing i found yesterday?
moritz TiMBuS: nope, I only rakudobugged the (my $ || my $) thing
TiMBuS oh 09:20
moritz miso2217: I don't really know, but I suspect it will be more work to emit something from STD than to do it manually
(except extracting keywords maybe)
miso2217: STD is intended as an exact parser, and keeps lots of information around, and then does conditional parsing based on that information. You don't want that for a syntax hilighter 09:21
those are all about cheating in a clever way :-)
TiMBuS what was it again?
rakudo: my $f = Match.new; say $f.clone;
p6eval rakudo 4bf132: OUTPUT«␤»
TiMBuS no its gotta contain something
moritz that's why we have IRC logs
:-) 09:22
09:22 awoodland left
woosley moritz: What's being hacking in the Perl6 world right now? 09:23
moritz woosley: jnthn works on the new meta object model for rakudo, I'm working on a spec for error objects 09:24
woosley: tadzik is hacking the module installer, and applied for a GSoC project to implement a Pod6 parser
sorear is hacking niezca 09:25
takadonet is working on his bioperl modules (iirc)
TiMBuS rakudo: my $f = 'a' ~~ /$<foo>='a'/; say $f.clone
p6eval rakudo 4bf132: OUTPUT«(timeout)»
woosley I think I saw a Pod6 parser on CPAN? 09:26
09:27 azalyn left
moritz yep, but that's in perl 5, and not integrated into rakudo, and implements an older spec 09:27
thing is, you are supposed to be able to access documentation of objects through the object itself
so the compiler needs to understand the doc syntax, and attach the documenation to the classes 09:28
09:29 domidumont left
woosley So at this time , this parser will be written in Perl6 09:30
moritz right
woosley Is this happening in the Rakudo repository?
09:31 birdwindupbird left
moritz it will, at least partially 09:33
(assuming his project is funded)

masak ah, here: www.codinghorror.com/blog/2005/06/a...volve.html
ah, and that one says Paul Graham said it too. I'm not surprised. 09:43
mathw I followed the link to the c2.com wiki page 09:45
the argument about the Visitor Pattern is quite enlightening
it finally makes me realise what I dislike about it so much
some part of my brain which already knew a language with multimethod dispatch must've been saying 'this is unnecessary crap'
right from the first time I encountered it

mathw The more I read this stuff the more I think I really should learn Common Lisp 10:15
but the syntax has always put me off
moritz same here :-)
that's why Perl 6 is like CL, but with a syntax :-)
mathw lol there is that 10:17
moritz the point is just that easy macros *require* an uniform syntax 10:18
so either you sacrifice macroability or readability 10:19
mathw very, very good point
moritz both options suck
mathw when your only syntax is S-expressions, it's easy to define new macros
moritz lips folks neglect syntax, we neglect macros
just a matter of opinions
mathw everything's really just a pile of compromises 10:26
the question is, which compromises are you willing to make? 10:27
This is why it's so valuable to learn more than one language and be willing to employ more than one language
different compromises lead to different problems being solvable with different difficulty

masak mathw: the syntax of Common Lisp puts you off... and yet you went ahead and taught yourself Lojban? :P 11:22
I think I've moved beyond being put off by Lisp's parentheses. the turning point for me was when I started reading really well-indented code. 11:24
the indentation guides the eye, and one can basically trust it and ignore the parens. 11:27

Tene 23andme.com/ is currently running a $0 sale, with a year commitment to their $9/mo update service. $108 is very reasonable. I've found my results from the service pretty fascinating. 12:46
mathw phenny: tell masak yes, I did. Lojban isn't full of parentheses!
phenny mathw: I'll pass that on when masak is around.
moritz Tene: is that the genetic sequencing service? 12:47
Tene phenny: tell masak currently big sale on 23andme.com/
phenny Tene: I'll pass that on when masak is around.
Tene moritz: Kind of. They identify 1M SNPs, which are one specific type of variation (single substitution of a base pair)
There's a general estimate that there are about 10M SNPs across humans globally. 12:48
23andme has reports for specific SNPs, drug response, disease risk, etc. They also give you access to the raw data, to do further research yourself. Look at snpedia.com/index.php/SNPedia for examples and links to research that references specific SNPs. 12:49
12:50 shozan left
Tene www.snpedia.com/index.php/Rs4680 is always my favorite example (I'm AA/Met Met) 12:50
moritz: it won't give you a full sequence of your entire DNA, but it gives you a pretty useful subset of common significant variations we've identified. 12:51
moritz wonders if he should give his wife such a set for Eastern 12:52
12:52 birdwindupbird joined
Tene They also let you opt-in to let them keep your sample on file, so they can re-run it on newer equipment, when they update. 12:52
It's a saliva sample, so no needles or blood or anything scary. 12:53
The "update service" is just giving you access to new reports they add, whether from new research, or old. Looks like they added a report on skin cancer a couple of days ago, for example, but if I wanted to follow the research myself, I could. It would just be a lot more work. 12:56

TimToady is not going to remove the indirect object syntax for various reasons. It resonates with other uses of colon. It decreases paren noise and increases formatting options for well-known method names like "new". Unlike in p5, it's not ambiguous. 16:41

masak the big point of that exercise, by the way, is that getter methods are contrary to the encapsulation that OO provides. and that TDD can be done just fine even without them. 19:08
isBEKaml masak: I think TDD doesn't require all of OO. The whole point of TDD is just that, tests and adherence to specs/behaviour. 19:09
irssi can be an infuriating at times. :/ 19:10
masak isBEKaml: yes. testing against getters causes a lot of bad coupling. 19:11

slavik tdd -> test before code? 19:23
masak slavik: no, but the two are related. 19:24
isBEKaml slavik: that would work too. the idea is to see if there's anything that you left out and see that things actually break where they are supposed to.
masak slavik: TDD could be used to apply tests after the code was written, too. but test-first goes really well with TDD. 19:25
slavik isBEKaml: but if you're coding the test, who is going to test the test?
isBEKaml slavik: you. :) 19:26

flussence_ there's no complement operator, since it's not possible to know in advance what bitsize you expect the output to be. 20:21
you'll have to xor with 0xFFFFFFFF if you want a 32-bit complement
PerlJam It would be nice to have a compliment operator though ... 20:22

isBEKaml masak: huffmanised tease.
slavik speaking of slavic languages ... kind of interesting that it is quiet a large family of languages which are very familiar 20:35
masak tadzik: actually, I don't. I don't play that game nearly enough :)
isBEKaml exactly what I meant. Swedish isn't that far off the slavic family from polish.
masak tadzik: why would one be afraid to say "Dare"? isn't Dare the non-scary option?
slavik except that all the names have a lot of jjjjjkkkkkk and such
moritz good for vim users :-) 20:36
slavik vowels are there for a reason!!!!!!!!!!!!!!!!!! :P
masak isBEKaml: er. Swedish isn't a slavic language.
tadzik masak: it depends on the company :)
slavik moritz: maybe vim users invented it?
moritz :-)
isBEKaml masak: Scandinavian,okay. :)
tadzik in colemak j and k are pretty far apparently
j is on qwerty 'y', k is on 'n'

isBEKaml masak: to be honest, I didn't include swedish in slavic family actually. :) 20:37

or is that a Truth or Dare question? :P

masak yeah. the King of Sweden, too.
tadzik slavik: your nick is pretty close to "Słowik"
and IKEA
I don't think that's one person
masak IKEA is a company, not a person.
isBEKaml tadzik: and slavic
slavik holy crap, 60% of Swedish population is made up of professional sc2 players 20:39
tadzik oh, so you all work for IKEA?
that explains LackRack
slavik that explains the poor packaging
stop being lazy!!!
