dduncan question, are there multiple NaN values or just one? the synopsis talk as if there is just one but I thought I read otherwise somewhere, such as a different NaN for each general reason we don't have a number 00:20
in the latter case, NaN sounds like a specialized unthrown exception 00:21

ash__: oh :) 02:00
oh look, the essay isn't copyrighted yet until 2010 02:01
heh
ash__ i like to think i can program, or am better at the programming side of 'computer science' but that may be a biased opinion

diakopter eternaleye: which one? the Stroustrup essay or the Softwareschneiderei GmbH post 02:05
eternaleye Stroustrup
diakopter ash__: re your degree-to-be, he writes 'Preferring the labels "software engineering" or "IT" over "CS" may indicate differences in perspective, but problems have a nasty way of reemerging in slightly different guises after a move to a new setting.' 02:08
imho, students should be awarded distinct measurements of achievement in their demonstrated ability in the areas of Problem/Goal Analysis/Identification and Measurement/Experiment Design/Implementation 02:12
the first category is Analyzing a Problem (and in the absence of having a Problem to Analyze), Identifying a measurable Goal for improvement 02:17
the second category is Designing and Implementing Measurements and Experiments, obviously :) Computers, their softwares, and the states of those softwares are the subjects/universe for compsci students, and the rest falls out from there. </hand_wave> 02:20
otoh, "Computer Scientists" Science is an very different discipline. 02:24

sjohnson hows it goin! 02:28
diakopter Blackberry data services down globally for 4 hours
eternaleye ouch 02:31
ash__ diakopter: my schools main distinction between CS and Software engineering is software engineers have more project based classes and have to take a few extra classes like software process vs cs that have to take more theoretical classes on programming and a few more EE-ish related classes 02:32
eternaleye ash__: What school? 02:34

mberends that Bjarne Stroustrup article cacm.acm.org/magazines/2010/1/55760...y/fulltext is close to my heart in sentiments but disappointing for lack of practical solutions 06:04
"teachers should program more", "students should write bigger programs", "only qualified programmers should be allowed to supply certain software". That last one whiffs of closed shop trade unionism. 06:08
I'd expected better from Bjarne 06:09

mberends +1 to "The Path to Rakudo Star" because it would be inspiring to have some glimpses into the mind of an awesome compiler design(er).
16:37 mariuz left
pmichaud yes, I was just thinking that perhaps the 24th advent post (blow people's minds away) would be a description of how the compiler works in the ng branch, showing off the regexes, action methods, etc. 16:37
moritz_ that would be awesome 16:39
+1 from me
masak pmichaud: yes; perhaps with relatively little focus on internals and much focus on the delivered functionality.
here's my highly subjective list of the posts poeple liked the most: .fmt, looping, .pick, given/when, roles, grammars/actions
(based on a combination of number of comments and my subjective tastes)
pmichaud okay, gotta run. Please add comments and suggestions... I'd be happy if the 24th post was a community post instead of just me :) 16:40

pugs_svn r29390 | pmurias++ | [mildew] fix smop backend 20:03
r29391 | pmurias++ | [mildew] refactor AST.pm to use MooseX::Declare
Tene My current implementation strategy is to cache the text of the macro body on definition, and then each time the macro is evaluated, set some context vars corresponding to what was matched, and call back into the compiler to ask for an AST of the cached macro body, with action methods that will check for the $*MACRO or whatever for the arguments to the macro. 20:04
20:05 kaare_ left, kaare_ joined
pmichaud Well, "cache the text of the macro body" triggers my "that doesn't smell right" sense.... but it may be correct in this particular application 20:06
rjbs macros aren't textual, are they?
pmichaud rjbs: we're talking in scheme, here.
rjbs had assumed they were some sort of parameterizable syntax tree mumblehandwave.
Tene Yes, also raises a warning for me.
mberends pmurias: sorry, I've not managed to get mildew to run (yet). If there are any instructions I'd like to know about them, otherwise I shall document while learning what to do. 20:07
Tene Um, I guess I *could* make something like that.
rjbs Even in Scheme, I'd think that. I'm just peanut-gallerying, though. Don't mind me.
pmichaud I'm not familiar enough with scheme macros to be able to say
rjbs should not be distracting anyone from "works and can be improved later"
Tene build an object that has an AST and also holds references to nodes in the tree.
pmichaud Tene: yeah, we may want a parameterizable AST or something like that 20:08
rjbs pmichaud: They must be syntactically valid, afaik, although they need not be semantically sensible outside the context of the macro. 20:09
Doh, I just tried to install mzscheme on this workstation and it failed. Instead, I will go shower and shave. &
20:11 Chillance_ left
Tene rjbs: I wouldn't be doing textual substitution, I'd be re-evaluating the same text each time in a different context. 20:11
So, effectively a parameterized AST, just with a shady implementation. :)
pmichaud Tene: anyway, I don't have much further comments about it at the moment. Perhaps the best first-cut is to go ahead with a text-based macro, just to explore it further and see what works or doesn't work. 20:12
Tene pmichaud: would you be comfortable with an implementation like that for rakudo, or would you much prefer to see some kind of parameterizable AST first?
pmichaud but also know that we're likely to throw it away
Tene Or do you withold judgement until you see an impl? :)
pmichaud well, for rakudo I'm wanting to avoid macros at the moment, unless the implementation is almost trivially simple 20:13
iirc, macros aren't on the critical path for rakudo star, and I'm a bit concerned that the specification is still immature
moritz_ it won't get mature unless somebody implements it 20:14
pmichaud moritz_: correct, but right now my focus is on getting the ng branch landed
I'm afraid that macros might end up being a huge distraction and/or pose difficulties for the other pieces that we *do* need to implement for Rakudo * 20:15
thus I'm in favor if the implementation is trivially simple
it could also be done in a branch
Tene pmichaud: If protoregexes get implemented as it sounded like the spec will flal out after talking with TT, I expect a macro implementation to be almost trivially simple. 20:16
pmichaud Tene: right -- so I'd need to review the spec changes
Tene pmichaud: what do you see as the current priority for work on ng?
20:16 Su-Shee left
pmichaud but one of the lessons of the past couple of years is that if advanced features go into the implementation too soon, it makes it really hard to refactor some of the core features later on 20:17
Tene :) yes.
pmichaud right now the priority has to be getting roles and classes back to where they were, list/array handling, and list assignment 20:18
20:18 Su-Shee joined
pmichaud I know I'm way behind on the list stuff 20:18
Tene Ah, yes, I was still waiting on that. I remember now. 20:19
pmichaud i just need a day's effort to finish it, but it also has to be a day with the right energy levels on my end
Anyway, I need to get back to my advent post or I won't be done in time.
Tene Yes, I'm done harassing you for now. :)
rjbs Tene: Right, I figured -- the difference being that you could crash earlier with an AST. Anyway, I think pmichaud is right to suggest "jfdi first and see how it goes" 20:22
20:22 KyleHa joined 20:26 bluescreen left
Tene rjbs: fwiw, it looks like S06 not only suggests textual macros, but also that an implementation should support macros of things that wouldn't be valid code on their own... unbalanced brackets, etc. 20:27
kinda like: macro start_debug { "if $debug {" }; macro end_debug { "}" }; 20:28
20:32 pdcawley joined
rjbs Tene: Weird. I will defer my worrying until later. 20:33

pmichaud also, if there's one thing that I think is a killer feature of Perl 6, it's the extensible grammar. 22:53
masak aye.
pmichaud and parsing in general
that, to me, is what will really set Perl 6 apart relative to its contemporaries
masak *cough* Lisp *cough* 22:54
oh. right. contemporaries.
pmichaud yes, I know Lisp can do that. But there's a reason nobody uses Lisp. :-)
mberends pmichaud: would it be too off topic to show an example of a DSL grammar?
pmichaud mberends: in the post? 22:55
mberends yes
pmichaud no, not too off topic at all, I don't think.
I didn't have a DSL in mind at the time :-)
mberends lolsql

mberends jnthn++ posted one somewhere 22:56

pmichaud github.com/jnthn/lolsql/blob/master...nhazsql.p6
it would be good if those were converted to protoregexes
mberends it's a bit big to add to the post in full 22:57
pmichaud <value> and <statement> would be good candidates for protoregexes there
especially statement
pmichaud reworks the grammar quickly
