11:03 < Kashia> for a bigger example, I think the xml de-serializing package
uses it
11:03 < jessta> ah, I see
11:04 < Kashia> Annotating fields with arbitrary information, quite a nice
idea :)
11:04 < jessta> it might be good to have it for methods, but it might be a
bit too constraining
11:05 < Kashia> I'm not sure.  I thought about it a little, and I'm not even
sure it's the right way to go.
11:06 < jessta> a field in struct has a specific use, the behaviour of a
method in an interface isn't really specific
11:06 < Kashia> yes, I came to that conclustion too

18:34 < sheb> i'm searching how to open and read a file
18:36 <+iant> e.g., os.Open, bufio.ReadBytes
18:37 < WalterMundt> I just tried to update to the new release and rebuild,
and it appears one of the tests is segfaulting: http://gopaste.org/view/324G6
18:38 <+iant> WalterMundt: that is odd; if it is repeatable please open an
issue for it
18:38 <+iant> I have not seen that
18:38 < WalterMundt> I'll rerun the build and see what happens
18:40 < dho> afternoon
18:40 < dho> iant: thanks for the reply
18:40 <+iant> I would be interested to hear what Russ has to say, but he is
off until 2010
18:40 < dho> yeah
18:40 < dho> it can certainly wait
18:40 < WalterMundt> I'm a bit surprised at the amount of flame over the
semicolon change.  I'm much more interested in things like how efficient the
scheduler gets or how cheap goroutines can get
18:40 < dho> not that time-critical

18:41 < dho> WalterMundt: in the general case, it makes all programs clearer
18:41 < dho> iant: pink.
18:41 <+iant> ha
18:42 < dho> and the number of projects who have style guidelines that
require the format to be similar to what go requires leads me to believe those who
aren't writing in that style are either novices or horrible spaghetti coder types
18:43 -!- leitaox [n=leitaox@] has joined #go-nuts
18:43 < dho> only difference I've noticed is the func foo(...) (...) {,

18:43 < dho> But it really does not matter *that* much.
18:43 < WalterMundt> *shrugs* I'm not inclined to care so much about style.
I was horribly offended by Python's whitespaceisms when I started with that
language and it's become one of my favorites for completely unrelated reasons.

18:46 < WalterMundt> I'm very happy not to have to drive much at all any
18:48 < WalterMundt> I've found that a walking "commute" (vs.  driving or
subway) makes life more pleasant out of all proportion with the amount of time one
spends on it.
18:49 < skelterjohn> i had a cycling commute for a while
18:49 < skelterjohn> it was pretty nice
18:49 < skelterjohn> rode through a park on the way to campus
18:50 <+iant> My commute is bike to bus
18:50 <+iant> walking would be better
18:50 < skelterjohn> two-step commutes are a drain
18:50 < skelterjohn> before i got my bike i had to take two buses to get to
the same spot
18:51 < WalterMundt> I go back and forth between bike and walking.  My last
commute was rush-hour NYC subway; quite a contrast (I'm not in NYC any more).
18:52 < skelterjohn> living in NJ doesn't make for nice commutes.  i drive
~30 minutes with low traffic, but my fiancee spends 90 minutes on the turnpike
every day
18:52 < skelterjohn> she hates NJ :'(
18:54 < WalterMundt> iant: bug evaporated after three builds.  I did the
second to test for reproducibility and the third to save complete build output to
a file for reference, and the output file was a clean build.  *shrugs*
18:54 < dho> heh
18:54 < dho> i hate nj :\
18:54 <+iant> oy
18:54 < WalterMundt> I would too in her shoes.
18:55 < skelterjohn> NJ is a wonderful place.  parts of it, anyway.  The
turnpike is not one of them.
18:55 < dho> s/wonderful/stinky cesspool of a/
18:55 < dho> (sorry)
18:55 < skelterjohn> I only wish this were in person so I could stare you
down convincingly
18:55 < dho> heh
18:55 < WalterMundt> Yeah, but how many people get to live in the nice parts
without having to spend a nontrivial chunk of their life on the turnpike?
18:56 < skelterjohn> and then do a fist pump
18:56 * dho is going to have to find a different parking spot
18:56 < dho> stupid city.  :(
18:56 < skelterjohn> people who work in NE jersey use the turnpike to get to
18:56 < skelterjohn> most populous bit of NJ, sure
18:57 < skelterjohn> I grew up in Princeton, which is quite nice
18:57 < skelterjohn> also, the northwest is really nice
18:59 < WalterMundt> well, I just ran what little code I've written through
the gofmt semicolon rinse and I like the results
19:00 < dho> yeah, like i said.  it's just people who don't like pink.
19:00 < skelterjohn> I like it better this way...  having them semi-optional
was weird
19:00 < skelterjohn> reminded me of pascal

19:47 < defectiv> those seem to be pretty fundamental array functions.

19:48 < dho> python will let you do similar things.
19:48 < skelterjohn> and for min, max...  that depends on the array elements
being comparable
19:48 < defectiv> of course.
19:48 < dho> but so will c, if you write it :)
19:49 < skelterjohn> so, not a function with an array as a receiver
19:49 < skelterjohn> maybe when some way of doing generics/templates comes
in, there will be a max(array) function
19:49 < defectiv> the issue is about how productive a language lets you be
out of the box.
19:49 < defectiv> there should be an array.max() function
19:49 < dho> I haven't had any issues with Go impeding me from being
19:49 < defectiv> lol.
19:50 < defectiv> dude, write a program in ruby.  then write it in go.  it
will take 4 times as long.
19:50 < skelterjohn> but there can't be an array.max() function, since not
all arrays have a max.
19:50 < dho> defectiv: and be 800 times as slow.
19:50 < defectiv> who cares?
19:50 < dho> I do.
19:50 < defectiv> performance is cheap.

19:50 < defectiv> you're economics are wrong.
19:50 < skelterjohn> *boggle*
19:50 < dho> lol
19:50 < defectiv> performance is cheap.  development is expensive.
19:50 < defectiv> buying twice as much hardware costs nothing compared to
buying more programmers.
19:50 < skelterjohn> i guess if you are ruby's target demographic
19:50 < defectiv> that economy was passed years ago.

19:51 < jessta> defectiv: buying twice as much hardware doesn't always make

19:51 < defectiv> because your employer is stupid?  i don't know.

server in the world.
19:52 < dho> Ok, that makes sense.
19:52 < defectiv> okay, describe your use case.
19:52 < dho> Thanks for that enlightenment.
19:52 * dho makes use of ignore list
19:52 < vegai> the ruby guys took "perfomance is cheap" to a rather sad
extreme, though ...
19:52 < defectiv> who cares about performance?
19:52 < skelterjohn> I'm a grad student who does machine learning research
19:52 < skelterjohn> things can take a long time if you aren't careful about
your algorithm design
19:52 < dho> In the case that you're not a troll: people who send a terabyte
of plain text email a day care about performance.
19:52 < defectiv> there are occasionally cases where performance really
matters, because your calculations can't be suficiently parallelized.  but they
are rare.
19:53 < Norgg> defectiv: Google, for one.
19:53 < vegai> defectiv: I work in a company whose one product is a web
application written in ruby
19:53 < vegai> defectiv: and oh boy do we care about ruby's horrible
performance in some cases
19:53 < defectiv> Norgg: i specifically cited the google model.  a case
where inefficiency is muliplied because of massive scaling.
19:53 < defectiv> then you probably suck at scaling.
19:53 < skelterjohn> anyway, saying "you're stupid because you think a
different subjective measure is important" is...stupid
19:54 < defectiv> well, that's not what i said.
19:54 < skelterjohn> you said that performance doesn't matter, only dev
19:54 < vegai> defectiv: can you imagine actions that take more than a
second?  More than 10 seconds?  More than a minute?
19:54 < dho> defectiv: All I know is that our product would not be able to
handle 11 million messages an hour if it were written in ruby.
19:54 < defectiv> in the VAST MAJORITY of cases.
19:54 < vegai> defectiv: how would you scale these out?
19:54 < defectiv> not 100% of the time.
19:54 < jessta> defectiv: I've heard a lot of companies that started with
ruby regret it due to various scaling issues

it is.
19:56 < dagle> I think I can do a thing that will be extremly slow on ruby.
19:56 < jessta> defectiv: does ruby have real threads yet?

19:56 < dho> defectiv: I'm skeptical that you think a full-featured SMTP
server written in ruby can handle >10 million SMTP conversations in an hour.
19:56 < defectiv> why can't it?
19:56 < jessta> defectiv: good to hear
19:56 < defectiv> that's a perfect opportunity for scaling.
19:56 < skelterjohn> i think he is implying that ruby code is slow
19:57 < dho> Well, the fact that it doesn't have anywhere near the runtime
speed of C, for starters.
19:57 < defectiv> ruby is slow compared to compiled languages of course.
but an SMTP server is just doing a massively scaled bunch of SMALL processes.

19:58 < vsmatck1> "when you're a hammer all problems look like nails"
19:58 < dho> Oh, I see.  Because we do hot-hot failover and make use of
thread pools and events in our software, we know nothing of scaling.
19:58 < WalterMundt> instead of, you know, writing a fast mail server and
saving thousands of dollars a day on power to not run all that ruby code
19:58 < dho> Clearly you know more about the problem space than we do.  Go

19:59 < dho> I suggest going to Facebook with the `volume is irrelevant'
19:59 < dho> They'll love that
19:59 < defectiv> they use php.
19:59 < dho> For their mail server?  No.
19:59 < defectiv> i believe.  or mostly at least.
19:59 < skelterjohn> for rendering....
19:59 < dho> They use our product.
19:59 < dho> Because it cut down the amount of hardware they needed by over
19:59 < dho> and I'd give you exact numbers if I was allowed to.
19:59 < vsmatck1> The facebook webserver is written in python IIRC.
19:59 < dagle> :)
20:00 < dho> But I'm not, but you'll have to take my word that it is an
order of magnitude.
20:00 < dho> When you are a large service provider, be it social network,
internet service provider, whatever, and you have literally tens of billions of
messages coming at you a day, you want them handled and you want them handled now.
20:01 < defectiv> dho that may be just the niche case where the economics
are in favor of faster code and more developer time.  you have a very narrow slice
of functionality ("doing email") that a team of good devs can write in a
reasonable time frame, even in a language like C or Go. and it does that same
operation SO MUCH that the savings on hardware make up for the greater cost of
developer time.

20:01 < defectiv> that's a pretty rare model though.  for general purpose

20:02 < skelterjohn> for general purpose programming, the idea that you can
jsut throw more hardware at it is also not so relevant
20:02 < dho> That's only applicable if you consider a large scale service
provider a `niche' case.

myriad of other functional languages for other systems.
20:02 < vsmatck1> I think the point is that this isn't the point.  There are
good email servers that already exist written in developer inefficient languages.
Use those.
20:02 < dho> In general computing, and by that I mean consumer computing,
you can never assume there's more hardware to throw at it.  Most people have 1
machine to run your software.
20:02 < defectiv> niche in that there is a very narrow problem space.
20:03 < WalterMundt> heh, Facebook is smart, they have Thrift and write
different bits of infrastructure in different languages depending on their needs
20:03 < dho> People who need speed get speed.  If your `general case' means
someone running a blog on their website, you're probably right in the assumption
that they don't need SuperFastAwesomeHTTPD
20:03 < dho> But that doesn't negate the fact that performance is critical.
20:03 < dho> Which was what you were asserting.
20:03 < vsmatck1> This is a stupid conversation.  I'm out.
20:03 < defectiv> sorry, i should have specified that i'm not really talking
about consumer computing.  although in general i think speed matters less in that
area, since the vast majority of applications don't have to be particularly
speedy, since most consumers have way too much processing power for their needs.
20:04 < jessta> vsmatck1: agreed

argument in favor of a language that can run code quickly.  sort of pointless to
try to convince him.
20:07 < defectiv> that have to scale, but don't scale to the extent that a
50% reduction in hardware requirements and power consumption would be worth the

seriously in-depth architectural designs that are scaled beyond just having more

performance trumps productivity.
20:07 < dho> Your initial argument did not provide that provision.  :P
20:08 < jessta> defectiv: but why write code just for the vast majority?
20:08 < slashus2> defectiv: There is the possibility that a programming
language will be able to run fast code and allow for quick development.  This is
what we are all shooting for.  Having a nice balance between them is optimal.

20:13 < skelterjohn> maybe you aren't doing something quite right.  the
tutorials need work too.
20:13 < defectiv> i can't then say "print("hello".to_upper_case())"
20:14 < skelterjohn> that's because "hello" is a string
20:14 < skelterjohn> not a MyString
20:14 < defectiv> i can say MyString("hello").to_upper_case()
20:14 < skelterjohn> yep
20:14 < defectiv> exactly!
20:14 < skelterjohn> one of the commandments of this language: always
20:14 < dho> What you propose would slow go down considerably, would bloat
binaries, and complicate the runtime.
20:14 < dho> I don't think the gain is worth the pain.
20:14 < dho> And I think most would agree.
20:15 < defectiv> you don't think that functionality could be added
20:15 < maikeru|> It's not much functionality you're adding, if any.
20:15 < defectiv> it's huge.
20:15 < dho> No, because then you get a bikeshed about which operations
string type gets
20:15 < skelterjohn> defectiv: how is the language to know what kind of
"hello" you mean?
20:15 < defectiv> when i wrote this program in ruby, it took so little time.
i could just crank it out.  everything just worked.
20:15 < skelterjohn> what if you have "type A string \n type B string"
20:15 < maikeru|> skelterjohn: Exactly.
20:15 < skelterjohn> and both have a version of to_upper_case
20:15 < defectiv> "hello" is a string.
20:16 < skelterjohn> how will the language know which to use?  you have to
tell it explicitly
20:16 < skelterjohn> that's the point
20:16 < skelterjohn> some languages have implicit ways to do this
20:16 < skelterjohn> they get confusing
20:16 < maikeru|> Besides, telling it explicitly is clearer to the other
programmers, I'd think.
20:16 < skelterjohn> go decided to draw the line early
20:16 < defectiv> it would do the version for the right type.
20:16 < skelterjohn> "right type"...
20:16 < defectiv> yes.
20:16 < defectiv> "hello" is not of type A or B
20:16 < skelterjohn> how would a person, even, know which one was right if
there were two that fit
20:17 < maikeru|> defectiv: And who's to say which is the right type?
20:17 < dho> ok, so say that you pass a type A down an interface{}
20:17 < skelterjohn> well, if it's just a string, then there is no
to_upper_case() method
20:17 < defectiv> some_word := A("hello")
20:17 < dho> It looks like an A.
20:17 < dho> But it looks like a B
20:17 < dho> but it looks like a string.
20:17 < defectiv> skelterjohn: yes, that is my complaint!
20:17 < skelterjohn> there are some string helpers in the strings package
20:18 < defectiv> i can't say func (word string) to_upper_case() string {}
20:18 < dho> So now communications channels need to push down additional
20:18 < skelterjohn> defectiv: of course not - your code doesn't own string
20:18 < defectiv> but they require you to say e.g.  to_upper_case("some
20:18 < skelterjohn> painful, i realize
20:18 < defectiv> who cares whether it owns it?  why not at least let it add
methods within its own scope??
20:18 < dho> I find that much more clear reading than "string".toupper()
20:18 < defectiv> and not affect other packages.
20:18 < defectiv> what?!
20:19 < dho> defectiv: My background is C.
20:19 < skelterjohn> defectiv: then you have a different type.  for
isntance, that type would implement an interface wtih the to_upper_case method.
if you tried to pass that string to another function in another package
20:19 < skelterjohn> then that package wouldn't know about your special code
20:19 < skelterjohn> and thigns would explode
20:19 < skelterjohn> bottom line: can't modify types that aren't yours
20:19 < defectiv> when a method is part of the class, it's like namespacing.
it keeps it clear what functions you have.  you don't have these "floating"
functions.  you can even say String.instance_methods and get all the instance
methods that are defined.
20:20 < dho> where is my goddamn tow truck
20:20 < dho> defectiv: so you're proposing that Go become an OO language.
20:20 < dho> I don't think you'll get that.
20:20 < dho> It's easy enough to implement OO concepts in Go
20:20 < defectiv> it IS an OO language according to what's his face in the
Go talk at Google.
20:21 < dho> Sorry, you're proposing that native processor types become
20:21 < defectiv> it doesn't do inheritance, but its interfaces provide a
similar type of functionality, and you have structs with methods.  it behaves in
an OO way.
20:21 < dho> I suppose you want integer.add(2) as well?
20:21 < maikeru|> dho: Ooh, can we have that?  Please?
20:21 < defectiv> of course.
20:21 < dho> How is that better than integer += 2
20:21 < defectiv> well, in ruby "4 + 5" is the same as 4.+(5)
20:22 < dho> I think you want Perl.
20:22 <+iant> one problem with permitting programs to define methods on
basic types is that it means that a single type won't have the same method set in
all packages, which makes runtime interface conversion complex
20:22 < defectiv> i hate perl.
20:22 < skelterjohn> iant: yeah i mentioned that
20:22 <+iant> sorry, missed it
20:22 < defectiv> iant well that was comparitively illuminating.
20:22 < skelterjohn> so did he
20:22 < dho> defectiv: if you're happy with ruby, why not use ruby?
20:22 < defectiv> i do.
20:23 < defectiv> i'm having a philsophical discussion about Go.
20:23 < dho> Ok, so why are you trying to turn $otherlanguage into ruby?
20:23 < defectiv> well, i'd like to see it do SOME things more like ruby.
20:23 < dho> philosophically, Go is not Ruby and does not desire to be
20:23 < defectiv> in general, i like Go a lot.  it is conceptually very
20:23 < skelterjohn> dho: i don't think that is the tack to take.  i think
that rather than saying "go is go, if you don't like it, don't use it", we should
say "go is go.  you can do lots of cool things in go, maybe you should use it"
20:23 < defectiv> it just seems to have a few rough edges.
20:24 < dho> skelterjohn: Sure, but when you've exhausted how you would do
similar things in Go and that's not good enough, the answer is use what you like

20:31 < defectiv> the idea of this simulation is to determine whether, with

have the backing that Go will have due to its support by Google.
20:36 < dho> well it is commercially backed.
20:36 < dho> but that's about the extent of my knowledge
20:36 < defectiv> it's Array::max
20:36 < dho> other than digital mars threatening sun for using the name D
for its DTrace language
20:36 < skelterjohn> so, defectiv, there are two ways to implement a general
max function
20:36 < skelterjohn> one is to use an interface with a compare() method
20:37 < skelterjohn> one is to wait for generics/templates
20:37 < skelterjohn> the first way, i think, would involve changing your
array to an array of this sort of interface

20:37 < skelterjohn> which is "free", according to a theoretical computer
20:37 < defectiv> so if i write a compare() method, then sort() can use it?
20:38 < skelterjohn> since it will take no longer than max
20:38 < skelterjohn> defectiv: i don't know what interface sort() takes,
it's in the docs somewhere
20:38 < defectiv> ah, i get it.
20:38 < defectiv> yeah i have it right here...
20:38 < defectiv> thx

20:38 < skelterjohn> i forgot what you...  of qsort
20:38 < skelterjohn> qsort is log-linear
20:39 < skelterjohn> which is not the same thing, according to a theoretical
computer scientist :)
20:39 < skelterjohn> or anyone else, for that matter
20:40 < skelterjohn> well, it's the same according to a mathematician
20:40 < skelterjohn> they generally ask "is it possible?" and stop there.
20:40 < dho> ok.  s/q//
20:40 < skelterjohn> sort is no faster...
20:40 < dho> it's precisely what you just suggested!
20:41 < skelterjohn> did not!
20:41 < skelterjohn> i left a blank.  someone else filled it in with "sort"

20:58 < maikeru|> WalterMundt: Well, that revision did not delete any client
data.  So I think that's a good sign so far :)
20:59 < Gracenotes> functional graph reduction is pretty intuitive
20:59 < Gracenotes> well, about as intuitive as OOP inheritance patterns
once you're exposed to it for a bit
20:59 < dho> it requires a style of thinking and problem-solving i do not
21:00 < skelterjohn> i thought that, i think it was rob pike, said it well
in the go video - when you have inheritance you tend to spend most of your time
designing inheritance trees
21:00 < skelterjohn> that struck home to me
21:00 < dho> I feel like with procedural programs, I tell it how to do a
21:00 < WalterMundt> I'm reading ejabberd code right now.  the
functional/FSM server model is kind of interesting
21:00 < dho> and with functional languages, it's like i'm specifying how a
solution would manifest
21:00 < dho> sounds subtly different in words, but i just don't think that
21:00 < Gracenotes> dho: the simplest way I tend to describe it: with
functional programming, you're not running procedures.  you're combining
21:01 < dho> yes, i've read / heard that before
21:01 < skelterjohn> i like'd dho's explanation better
21:01 < skelterjohn> it's how i think of it, too
21:01 < Gracenotes> it makes the flow of data a lot more clear, too.
21:01 < dho> except maybe s/how to do a solution/how to solve a problem/
21:01 < skelterjohn> in functional programming (and my functional experience
is limited to scheme), i just tell it what the solution is
21:01 < WalterMundt> I feel almost equally at home in either camp, which I
suppose is why I like languages that let you mix idioms
21:02 < dho> that and the functional purists scare me
21:02 < Gracenotes> dho: complicated inheritance trees is one of the points
of OOP
21:02 < Gracenotes> I do not like
21:02 < Gracenotes> and that was more @ skelterjohn, re.  rob pike
21:02 < Gracenotes> the reason it exists is because dynamic dispatch in
these languages is so limited
21:02 < skelterjohn> i TA'd for a class "software methodology" where we did
OO design in java
21:02 < WalterMundt> I've rarely seen an inheritance tree that made the flow
of data in a program clearer; most often it's the opposite
21:03 < skelterjohn> and twisting some models to fit the single inheritance
idiom was tricky sometimes
21:03 < Gracenotes> that, combined with the sometimes contradictory need to
reuse code, can result in some messed-up trees
21:03 < Gracenotes> IS-A is a strong relationship, much stronger than
21:04 < dho> I'll put it another way
21:04 < dho> Functional languages are why I end up sounding like a douchebag
when people tell me I'm really smart.  I say `I guess.'
21:05 < skelterjohn> fun things to do on the internet: brag about people
telling you you're smart =p
21:05 < defectiv> is google (or any of you) using Go "professionally"?
21:05 < dho> Yeah, you sound like a douchebag either way
21:05 < defectiv> skelterjohn: lols
21:05 < skelterjohn> defectiv: Go isn't ready for it, in my opinion
21:05 < dho> Though that's also probably partially due to the environment I
keep myself in.
21:05 < skelterjohn> there are memory issues
21:05 < defectiv> it's so funny you mention that, cause my mom just told me
how smart i am.
21:05 < WalterMundt> *facepalm*
21:05 < defectiv> also, matt gonzalez just emailed me about having lunch in
his law firm soon.  good times.
21:05 < Gracenotes> well, it tickles my brain.  plus it gives me an excuse
to learn about discrete math.
21:06 < dho> it's so funny that you mention that, cause your mom just....
21:06 < Gracenotes> I just have an unhealthy attraction to theory :(
21:06 < dho> (sorry, had to)
21:06 < defectiv> dho nice
21:06 < skelterjohn> defectiv: for instance, if you have a one-off goroutine
that just pumps values into a channel in an infinite loop, it will never get
cleaned up (even if that channel is forgotten about everywhere else)
21:06 < defectiv> theory is more fun than practical stuff.
21:06 < skelterjohn> this is relevant for things like Vector.Iter()
21:06 < defectiv> huh?
21:06 < dho> Anyway, back on what I was saying.  Since I've had no
scholastic experience with anything outside of high school, I've pretty much kept
myself in the company of people who are worlds smarter than I am
21:07 < dho> and ever will be
21:07 < skelterjohn> so, Vector.Iter() pumps all the values it has into a
21:07 < skelterjohn> if another thread calls Vector.Iter() and reads some,
but not all, of those values, the spawned goroutine will never be cleaned up
21:07 < defectiv> dho that's hard sometimes.  like this dude i know who
worked at intel and now google, that i studied computer engineering with.  he just
always made me feel so inferior.
21:07 < dho> Well, I do it because I have to learn shit somehow
21:07 < defectiv> he could recite maxwell's equations a year after taknig
electromag with me.  wtf.
21:08 < dho> and again, not to be douchebaggy, but if i hadn't, there'd be
no way that i'd be making the salary i do now
21:08 < skelterjohn> well that's useful.
21:08 < defectiv> it's like, how can your brain do these things that my
brain cannot?  i hate you...  and want you to die.
21:08 < Gracenotes> a good system for parametric polymorphism prevents your
language from becoming a static typing system implemented on top of a dynamic
typing system implemented on top of another static typing system

21:09 < dho> It's hard to objectively know how good you are if you know a

21:09 < defectiv> does Go do that?  does C++?
21:09 < skelterjohn> what are you referring to
21:09 < Gracenotes> Go has a static typing system.  weird interface{} hacks
are used.  It is converted at some point back.  in all this type safety is ensured
in individual conversions...  but not the entire operation.
21:10 < skelterjohn> oh
21:10 < taruti> Gracenotes: interface{} is mostly needed because the current
lack of generics.
21:10 < Gracenotes> yes, as I said.  "good system for parametric
polymorphism prevents your language from becoming [...]"
21:10 < taruti> and in some places to mean "anything that reflection will
21:10 < dho> So, as an aside, if generics come in, what's the use case for
21:11 < skelterjohn> unless generics are defined with functions, then...
21:11 < taruti> dho: things wanting to use refletion.
21:11 < skelterjohn> the same use they already have
21:11 < taruti> dho: e.g.  enc/binary, gob, ...
21:11 < skelterjohn> ah, i get it now
21:12 < skelterjohn> maybe i will come back with a more appropriate response
21:12 < Gracenotes> dho: well.  Implementing an open union types, since Go
doesn't even have a finite union type (tagged union).
21:12 < skelterjohn> no guarantees
21:12 < Gracenotes> that might be a use for interface{}
21:12 < taruti> Gracenotes: that is being fixed.
21:13 < Gracenotes> yes, that would be nice.  parametrically polymorphic
unions would be very awesome too.  I just like Hindley-Milner a bit, you know,
sort of a flaw of mine >_>
21:13 < skelterjohn> what Gracenotes said.  i can add two things to a list
that are both compare()-able and then sort it.  with generics its likely that
they'd have to be the same exact type

21:36 -!- Ryan____ [n=ryan@cpe-98-27-166-221.neo.res.rr.com] has joined #go-nuts
21:36 < jessta> the problem is that doing CS is expected of programmings,
but that's mostly due to the fact that CS used to be the only computing degree
21:37 < skelterjohn> as such, i will never be a professor :)
21:37 < WalterMundt> skelterjohn: interesting.  I dropped out of college to
take a job.  Someday I might be interested in graduate-level classes.  I'm
perfectly capable of picking up most undergrad-level stuff on my own, and would
generally rather read a textbook than listen to lectures, anyway.
21:37 < jessta> *programmers
21:37 < dho> Anyway, my desire is really to make a course for kids who will
end up writing code for a living
21:37 < dho> i say kids; i'm 26
21:37 < dho> so
21:37 < jessta> so people who want to be software engineers do CS and are
useless at software engineering
21:38 < dho> jessta: right; that's sort of the problem i want to address
21:38 < skelterjohn> jessta: good programmers started early
21:38 < WalterMundt> jessta: it's a real problem.  ACM ICPC saved me from
that to a degree, but that's not a path for everyone
21:38 < skelterjohn> and studied on their own
21:38 < skelterjohn> rarely does a set of courses make someone into a good
21:38 < WalterMundt> skelterjohn: that's the question though
21:38 < vsmatck1> There was a good article on this subject recently by
21:39 < jessta> I specifically did CS because I like CS, but my CS degree
contained way too much software engineering
21:39 < WalterMundt> skelterjohn: can we do better than CS courses at that,
for people who weren't writing C in middle school?
21:39 < dho> skelterjohn: A set of courses should be able to prepare someone
for that.
21:39 < jessta> for the same reason as above
21:39 < skelterjohn> WalterMundt: I think teaching people C in middle school
should be the norm :)
21:39 < vsmatck1> He's kind-of unique in that he was a software engineer for
a long time before becoming a professor.  He also teaches intro programming
21:39 < dho> I didn't start with C until I was around 21, and then not
professionally until I was 23 or so.
21:39 < WalterMundt> skelterjohn: ooh, I like the way you think
21:39 < skelterjohn> dho: any experience before that?  if not, then you are
21:40 < dho> maybe 19 or 20
21:40 < skelterjohn> in my opinion
21:40 < jessta> for some reason employers to employ programmers who have a
software engineering degree that is called "computer science"
21:40 < dho> I did qbasiclol when I was 11/12
21:40 < Gracenotes> you and me both, dho :o
21:40 < skelterjohn> any early programming helps
21:40 < skelterjohn> my first programming language was hypertalk (we had a
21:40 < dho> from that, it was html, minor MINOR dabblings in perl at 16,
and then PHP when I turned 17
21:40 < dagle> I would say CS course are what you make the to.  If you don't
want to learn anything you can pass the course with out it.  But if you want to
learn stuff it's a great way of doing so.
21:40 < vsmatck1> At my school they wanted everyone to do their own work so
they forbid working on programs in teams *facepalm*.
21:40 < jessta> dho: same here
21:40 < dho> oh, yeah, and i dicked around with object logo when i was
<10 though i remember none of it
21:41 < WalterMundt> I started with pascal and then went to basic/C and then
bash/C++ and later Java/etc.
21:41 < skelterjohn> logo was fun
21:41 < dho> it helped that wrox press was in such shambles that i got to
coauthor a couple books on php
21:41 < jessta> qbasic at around 10 and php 16-17, then C

21:46 < skelterjohn> it's theory and hardware.  sort of a weird mix.
21:46 < dho> oh
21:47 < dho> I thought the GRE was just general graduate
21:47 < skelterjohn> the CS subject GRE, that is.
21:47 < dho> ah
21:47 < skelterjohn> the general one is trivial...the math section anyway
21:47 < skelterjohn> didn't try too hard for the other sections and i
performed acordingly
21:47 < WalterMundt> I took a sample GRE, the vocab stuff on the English
side was a little out there to me, and I'm a voracious reader

21:48 < dho> My vocabulary decreased when I learned Dutch
21:48 < skelterjohn> though i read scifi rather than 19th centuray brit lit

22:51 < gracchus> one "target" == one func main() though, which is enforced
22:51 < gracchus> ?

22:53 < skelterjohn> yes
22:53 < skelterjohn> it's all moot at this point - the project is going in a
different direction

22:53 < dho> skelterjohn: feel free to use goober, it does most of that
right now
22:53 < zaker_> i just wonder why the square brackets used to declare and
use arrays are switching from prefix to post-fix, example: var array []int =>
array[i]....  instead of just keeping it prefix?
22:53 < dho> sort of

22:54 < skelterjohn> dho: did you do more with goober?
22:54 < dho> no but it's trivial to get it to work
22:54 < skelterjohn> heh
22:56 < WalterMundt> you know, I find the use case of running the builder in
a subdirectory to be interesting.  I don't want you to have to put a build file in
every dir, but it would be nice to have the builder just build the package of the
cwd if run with no args in a package's directory
22:57 < WalterMundt> maybe have a builder that searches up the tree for a
build file by default
22:57 < skelterjohn> maybe after this deadline i'll put it together
22:57 < skelterjohn> alternatively, maybe i won't feel like implementing
something that does only a subset of the current gb proposal
22:57 < skelterjohn> :)

23:04 < napsy> Hello.  How do I iterate through list.List()?
23:04 < skelterjohn> l.Iter()
23:04 < dho> WalterMundt: the issue with that is directories like pkg/io
23:04 < napsy> ok but how do I use this?
23:05 < skelterjohn> var l list.List = ...  \n for val := range l.Iter() {
...  }
23:05 < napsy> oh ok
23:05 < dho> WalterMundt: if you have a makefile in pkg/io, how do you know
that pkg/ioutil is a different package without scanning files in it
23:05 < dho> or that they're not supposed to be linked together
23:05 < WalterMundt> I've not looked in there as of yet
23:07 < WalterMundt> Are they separate?  Because I'd say the sane default is
to presume different directories are separate packages and attempt to auto-resolve
any dependencies regardless of their hierarchical relationship within the source
23:08 < napsy> skelterjohn: ok I have the iter but how to get the data now?
23:08 < skelterjohn> I think having the source for one package inside the
directory for another is pretty weird
23:08 < WalterMundt> again, absent any build instructions beyond a marker
file at the root
23:08 < skelterjohn> napsy: like i said - a for/range.
23:09 < WalterMundt> skelterjohn: if the package is going to be named
io/ioutil, having it be in src/pkg/io/ioutil makes perfect sense to me
23:09 < napsy> skelterjohn: I created the for loop but now I don't know how
to get the data from the item
23:09 < skelterjohn> WalterMundt: I think having a package named io/ioutil
is weird :)
23:09 < WalterMundt> therein lies the difference between us then
23:09 < skelterjohn> napsy: val is the data.  each iteration of the for loop
will assign a different element to val
23:10 < napsy> skelterjohn: yes but if I try to print the data (string) I
get pointers
23:10 < skelterjohn> then the data isn't strings :)
23:10 < skelterjohn> try val.(string)
23:10 < napsy> ok
23:10 < skelterjohn> a list.List has interface{} as its elements
23:10 < WalterMundt> I see nesting related packages as normal, and in a
similar vein to the function of packages in other languages like Python and Java
23:10 < napsy> skelterjohn: oh it works now, thanks

joined #go-nuts
23:10 < WalterMundt> though I am very thankful that go hasn't gone the Java
route wrt package naming
23:11 < dho> val.(string) is really weird
23:11 < skelterjohn> napsy: val is of type interface{}
23:11 < dho> i've always found that a little too verbose
23:11 < skelterjohn> it happens that string implements that interface
23:11 < skelterjohn> dho: until generics, that's how it goes
23:11 < dho> yeah

23:16 < skelterjohn> the alternative is way too verbose, but it seems weird
to me that you don't have to wrap everything in interface boxes when you pass them
as parameters
23:17 < skelterjohn> in the way that you have to say "var i int =
int(aFloat)" instead of "var i int = aFloat"
