02:53 < ender2070> because Lua sucks
02:53 < Nola> That's not an answer to my question
02:54 < Nola> I asked why Go is slower (and Go is a statically compiled
language)
02:54 < Namegduf> Nola: Slower in what benchmarks?
02:54 < Nola> all of them
02:54 < kimelto> Lua rocks
02:54 < ender2070> Go does a hell of a lot more than Lua
02:54 < Nola> ~3 times slower
02:54 < Namegduf> WHICH specific benchmarks?
02:54 < ender2070> Lua is for bullshit WOW addons
02:55 < exch> lua is actually quite a nice language
02:56 < kimelto> it's nice to embed a scripting langage in your C program.
02:56 < ender2070> python > lua

02:58 < Nola> example?
02:58 < Namegduf> Do you mean the Shootout benchmarks?
02:58 < Nola> Namegduf: That's one set of benchmarks showing Go is slower
than dynamic languages, Yes
02:58 < Namegduf> Nola: What does dynamic vs static have to do with speed?
02:58 < Nola> In my own benchmarks for my target application and domain
(music and DSP audio) -- go was 3 to 10 times slower than Lua

02:59 -!- kota1111 [~kota1111@gw2.kbmj.jp] has joined #go-nuts
02:59 < Nola> Namegduf: It has to do with the fact that I expect a static
language to *at least* be much faster
02:59 < exch> would be interesting to see the code you used for those tests
02:59 < Namegduf> Nola: Then your assumption is flawed
03:00 < Nola> its reasonable assumption
03:00 < Namegduf> Not really
03:00 < Nola> Then why would I use a static language?
03:00 < Namegduf> Type safety is a feature
03:00 < Namegduf> Not a drawback.
03:00 < Nola> umm
03:00 < Nola> type safety doesnt require execution time
03:00 < Nola> Its not like lua would be slower if it had "type safety"
03:00 < Namegduf> No, I didn't say it did.
03:01 < Nola> THen what are you saying
03:01 < ender2070> Nola - i'm sure there are tests where Go would be 3 to 10
times faster than Lua
03:01 < Namegduf> I said the feature that statically typed languages offer
which dynamically typed languages do not
03:01 < ender2070> right tool for the right job
03:01 < Nola> Its ok that Go is slow ..  because it has type safety ? Lol?
03:01 < Namegduf> No?
03:01 < Namegduf> No, I don't think I said that at all
03:01 < Namegduf> At any rate, the answer is obvious
03:02 < ender2070> Nola, does Lua support concurrency and garbage
collection?
03:02 < Namegduf> LuaJIT successfully JITs Lua to achieve C-like speed
03:02 < Namegduf> Go's compilers have yet to be nearly that optimised
03:02 < Namegduf> Go is a young language and the compilers are not very
heavily optimised at all
03:03 < ender2070> not only that
03:03 < ender2070> hes comparing apples and oranges
03:03 < Namegduf> Additionally, specifiic things like the regex library are
unoptimised
03:04 < Namegduf> It's most likely a compiler optimisation difference.

0.3.2]
03:08 < Nola> It's pretty simple
03:08 < d_m> according to http://tinyurl.com/37s8sbj go is mostly faster
than lua in execution time (faster on pidigits, slower on almost everything else).
that said, implementation != language, and lua is nice, so use it if you want.
03:08 < Nola>
http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=go&lang2=gpp
03:08 < Nola> 3 to 34 times slower than C++
03:08 < Nola> so its useless
03:08 < exch> nobody is forcing you to use it :p
03:09 < exch> Lua and c/c++ have had years to mature.  Go is barely out of
the womb
03:10 < Nola> ok
03:10 -!- slashus2 [~slashus2@74-137-24-74.dhcp.insightbb.com] has joined #go-nuts
03:12 < ender2070> he already sounded like a troll
03:13 < Nola> That's not what they're billing the language as
03:14 < Nola> From the front page of golang.org, it says "Go compilers
produce fast code fast.  Typical builds take a fraction of a second yet the
resulting programs run nearly as quickly as comparable C or C++ code."
03:14 < Nola> So I looked into it, and it's not true
03:14 < Namegduf> Go's principle feature *at present* is not speed.  It is
the ease of producing *safe* and elegant code in a relatively simple to reason
with language.
03:15 < Namegduf> However, it is much closer to C/C++ than many newer,
interpreted often, languages are, at least normally.
03:15 < ender2070> Nola - I heard the creator of Go boast mostly about
garbage collection and concurrency
03:15 < ender2070> Lua doesn't even have garbage collection
03:15 < Namegduf> Python, PHP, Perl, Ruby, are all a nice set of common ones
which make 3x slower look like nothing
03:15 < Namegduf> Java is as fast as C (almost) but uses much, much more
memory and has horrible startup times, compared to Go
03:16 < KirkMcDonald> No one seems to remember D in these comparisons.
03:16 < Namegduf> C++ could get faster, perhaps, but it'll never be close to
as fast to write fast and good reliable code in.
03:17 < Namegduf> KirkMcDonald: I always thought it was implicitly "C++ but
actually worse"
03:17 < KirkMcDonald> heh
03:17 < KirkMcDonald> It may be shit, but it is reasonably performant shit,
modulo the GC.
03:17 < Nola> D is "C++ but you cant implement realtime stuff"
03:18 < KirkMcDonald> Sure you can do realtime stuff, you just need to know
how to convince the GC to do what you want.
03:18 < Nola> That doesn't work Kirk
03:18 < Nola> There's no way to control stopping the GC on a per-thread
basis
03:18 < Nola> And collection is stop-the-world
03:18 < Namegduf> Nola: Anyways, the "nearly as fast" is at present a "to be
implemented" thing.
03:18 < KirkMcDonald> By "convince the GC" I mean "preallocate and disable
the GC."
03:18 < Nola> Doesn't work, kirk
03:18 < Namegduf> Abysmal cases like 34x slower aren't a language problem,
they're a library problem
03:19 < Nola> If you disable the GC because your audio thread needs realtime
performance, now you've got a non-working GC for your GUI

03:19 < KirkMcDonald> Nola: It worked for the Deadlock team.
03:20 < Nola> anything they did would be a hack/workaround/evil deed
03:20 < KirkMcDonald> Yes, I think that goes without saying.  :-)
03:20 < Nola> surreptitiously "hiding" a thread from the GC
03:20 < Nola> without language support
03:21 < exch> if it does what you need it to do, then does it really matter
if it's 'evil'?  :p It's just a tool for a job
03:21 < Nola> and since when do you say D is shit?
03:21 < Nola> you've been a D evangelist
03:21 < KirkMcDonald> Nola: I like D-the-language reasonably well.
03:22 < KirkMcDonald> Nola: D-the-actual-reality-of-the-toolchain has some
severe issues.

03:23 < Nola> heh, LuaJit is almost as fast as DMD
03:23 < KirkMcDonald> Though admittedly the last time I seriously wrote
something in D was about three years ago, however, I do not believe the situation
has fundamentally changed in that time.
03:24 < manveru> i wish 'type' wasn't a keyword...
03:24 < KirkMcDonald> manveru: Call it "kind" instead.
03:25 < manveru> yeah...

precious processor cycles.

10:00 < micrypt> How does setting defaults in type structs work?
10:02 < wrtp> micrypt: the default is zero.
10:03 < bortzmeyer> micrypt: "Otherwise, each variable is initialized to its
zero value.  " http://golang.org/doc/go_spec.html
10:04 < micrypt> wrtp: Thanks.  Would something like this work?
http://pastebin.com/gfv8ZyFT
10:04 < micrypt> bortzmeyer: Thanks.
10:07 < wrtp> micrypt: no, that's a syntax error
10:08 < wrtp> zero values are quite a fundamental part of go.  it's worth
working with them, rather than struggling against them...
10:08 < micrypt> wrtp: Okay, so I ought to pass them in at creation.
10:09 < wrtp> micrypt: not necessarily.  you could just set them in the
NewClient function
10:10 < micrypt> wrtp: Yeah, that's what I meant.  Thanks a lot.
10:10 < wrtp> and then let the user of the API change them if it needs to
10:10 < wrtp> micrypt: to avoid setting all the fields individually, you can
have a global var that holds all the fields and their default values
10:11 < wrtp> so below your type Client, you'd have var defaults =
Client{URL = SANDBOX_PATH, Client = DEFAULT_CLIENT, ...  }
10:16 < micrypt> wrtp: Thanks, I'll look into that.
10:21 < wrtp> micrypt: oops, s/=/:/g in my line above
10:21 < wrtp> as in, the '=' characters should be ':' characters
10:21 < wrtp> apart from the first one, obviously :-)
10:22 < micrypt> wrtp: I noticed.  :P

In general, a conversion succeeds if the value of x is assignment compatible with

15:28 < manveru> i wouldn't even know how to tell go to link static
15:28 < leimy> gcc -static
15:28 < manveru> all those 6g/6l flags are cryptic
15:28 < leimy> if tat's your linker :-)
15:29 < manveru> no, i heard gccgo isn't quite here yet
15:29 < manveru> anyway, this really makes distributing my stuff hard
15:29 < leimy> fair enough
15:30 < leimy> Why?!
15:30 < leimy> how could it be easier with no dependencies?
15:30 < leimy> you'll never have to support an end user having a wrong .so
lib
15:30 < leimy> EVER
15:30 < leimy> :-)
15:31 < leimy> I mean this might give a system administrator heartburn
15:31 < leimy> as the don't know what's got what linked to what.
15:31 < manveru> http://paste.pocoo.org/show/218104/
15:31 < leimy> yep I've got a go binary running right now that when I do
"ldd" on it it just says "statically linked"
15:32 < manveru> so if i distribute that, i have to tell people to goinstall
Go-SDL and Go-OpenGL, then go in their directories and run a manual `make` as root
because goinstall messes up...
15:32 < leimy> Once you start walking the path of C interoperability, you
pull in the evil world of shared libs :-)
15:32 < manveru> and all that without knowing that those libs don't mess up
the go install itself
15:32 < leimy> nope...  you need them to have exactly those libraries you
got from ldd
15:32 < manveru> well, there are no alternatives to C
15:33 < leimy> and the go install is not needed on the machine you want to
run go programs on.
15:33 < leimy> just the files listed there.
15:33 < manveru> but how do they build it then?
15:33 < leimy> You said "distribute" not "distribute source"
15:33 < manveru> well, that's the same
15:34 < manveru> at least if you think of gentoo or archlinux
15:34 < leimy> See this: http://5ttt.org/
15:34 < leimy> That's a go social networking application for 3 different
programs, distribtued as 64bit binaries, and you don't need Go to run it as far as
I can tell.
15:34 < leimy> This guy is "distributing a go program" :-)
15:35 < manveru> yeah, the freenet alternative?
15:35 < leimy> he chose not to release any source at all.
15:35 < leimy> I have no idea, I've never run it :-)
15:35 < manveru> so what about 32bit guys?
15:35 < leimy> he'd have to make you a build
15:35 < manveru> exactly
15:36 < leimy> Well his life is simplified in that he only supports the
builds he's done :-)
15:36 < manveru> i can't stand closed source anymore...  waiting for adobe
and skype to get their act together for 6 years already is enough

nice thing to do and bless you for doing so.
15:37 < leimy> but if you don't, oh well.  Some people might still find that
binary useful :-)
15:37 < manveru> i have never released anything without source

15:39 < manveru> i just try to make it easy for other people to build it,
either to just run it or to contribute
15:39 < leimy> yeah, and sharing source is the way to go there.  :-)
15:39 < leimy> I'm not saying it's bad to share source, in many cases it's
the only way to go.
15:39 < manveru> obviously someone can provide binary versions from that
easily
15:39 < leimy> exactly
15:39 < leimy> but you have less to support if you don't :-)
15:40 < leimy> or you can give the source and say "I only support my builds"
15:40 < manveru> oh well
15:41 < manveru> i just miss some easy alternative to ruby's $RUBYLIB that
allows you to influence the load path
15:41 < leimy> LD_LIBRARY_PATH ?
15:41 < leimy> that's what ELF platforms use right?
15:41 < manveru> i guess, i don't know c that much
15:41 < leimy> Yeah, that's the runtime linker's library path
15:41 < leimy> you can override system defaults with it.
15:42 < manveru> is there something like that for go?
15:43 < manveru> i could adjust the import path and bundle the libraries i
use
15:44 < manveru> that's how many larger apps do it anyway
15:45 < manveru> and if i wrap the calls to that library i can localize the
import to a single file
15:46 < manveru> i'm still puzzled over why go requires you to import
libraries per file and not per package
15:47 < yebyen> ?
15:47 < yebyen> you don't
15:48 < yebyen> you compile a package into a standalone .a
15:48 < yebyen> and then you link that in
15:48 < yebyen> but, you can only link it in to a go program
15:48 < manveru> if you use the math package in a.go and b.go, both
belonging to package x, you have to import "math" in both files
15:49 < yebyen> manveru: of course, that's what you mean
15:49 < yebyen> doesn't that make sense?
15:49 < yebyen> if the symbol "math" is in this file, there should be an
explanation in this file of what it means
15:49 < yebyen> import "math"
15:49 < manveru> it might make sense as an option, but i think it's
cumbersome

15:50 < manveru> if my compiled app has the math lib anyway, i might as well
refer to it from elsewhere
15:50 < yebyen> or var math
15:50 < yebyen> hmm
15:50 < yebyen> i see what you're saying
15:50 < yebyen> if i'm declaring a global variable
15:50 < yebyen> i only need to do it in one file for the whole package
15:50 < yebyen> but, if it's a package...
15:50 < manveru> right now i have to toggle stuff like import . "fmt" over
various files if i use debugging output

15:51 < yebyen> you can easily invent a better way to do debugging output
15:51 < manveru> even if i use it all the time in other parts of the package
15:51 < exch> you are saying that if a and b import math..  and then a and b
get linked into c, c will contain all math code twice?
15:51 -!- barismetin [~barismeti@kde/developer/baris] has joined #go-nuts
15:51 < exch> there's bound to be some issues there with duplicate symbol

15:51 < yebyen> exch: no, we're saying that it's kind of arbitrary to have
global variables that you can define once anywhere in the package
15:51 < manveru> exch: i don't think so
15:51 < exch> right, fair enough
15:51 < yebyen> and then turn around and say, the package import statement
must be specified in every file in the package
15:52 < exch> I suppose that's a bit odd
15:52 < yebyen> global variables are a bad policy anyway
15:52 < manveru> but i also cannot say something like: import(mymath
"math"); math = mymath

15:53 < yebyen> are there operations you can perform on a package name?
15:53 < manveru> not that i know of

that
15:53 -!- Kashia [~Kashia@port-92-200-76-15.dynamic.qsc.de] has joined #go-nuts
15:54 < yebyen> if the package is not an object, i guess it would have no
reflection of any kind
15:54 < manveru> so right now go drives me towards wrapping all calls to
other libraries into in-package functions just so i don't have to import all over
my files the same libs
15:54 < yebyen> import neutrino
15:54 < manveru> Kashia: oi
15:55 < manveru> i don't see how this has anything to do with global
variables though
15:55 < Eko> manveru: contrariwise, go gives you the ability to only import
the necessary packages to compile each individual file
15:56 < manveru> uhm
15:56 < yebyen> manveru: if you're debugging one file, you only need to add
the import statement for your debugging/logging package in that one file
15:56 < manveru> if they belong to the same package, it usually means you
have to compile _all_ files anyway since they depend on each other
15:56 < yebyen> manveru: if you're debugging multiple files in one package,
try making your debug statement a closure
15:57 < manveru> of course i could put all code into a single file, that
would solve it....  :P
15:57 < yebyen> manveru: and assign it to the global variable somewhere in
your package
15:57 < yebyen> then, your other package files in the package won't need to
import anything, just call the closure variable
15:57 < yebyen> it's kind of a bastardized use of closures
15:58 < yebyen> but it exploits the fact that global variables are declared
semantically different from package imports
15:58 < yebyen> manveru: do you know what i mean?
15:58 < manveru> yeah
15:58 < manveru> and i don't think i like that much better
15:58 < yebyen> well
15:59 < manveru> sorry to be all ranty today :)
15:59 < Eko> if you're talking about debugging, I have an elog package that
I wrote which allows me to send all of my logging to a Logger object and it
filters the output based on the level I associate with it; so when I'm done with
debugging, I can set the filter level up and only get warning and error messages.
15:59 < yebyen> Eko: great, you can pass that logging object around, or put
it somewhere in scope of the closure that we're talking about, and pass that
closure around
15:59 < yebyen> that's really more what you should be doing
16:00 < Eko> I've been conditioned to not use globals, so I pass it around
or store it in objects, lol
16:00 < manveru> i usually just use Println statements to narrow down weird
behaviour, when i'm done with that i remove them, and of course have to remove the
import as well
16:00 < yebyen> manveru: right...  so, have this in some file
16:01 < yebyen> import "fmt"; var dbg=func(d string) { fmt.Println(d) }
16:01 < yebyen> then, anywhere in your package, you can call dbg("the
message")
16:01 < Eko> I've learned to write debug statements (using level FINEST)
that are meaningful enough that I don't feel the need to remove them, but I don't
feel bad leaving them in the code when I can't ever see its output when I set the
filter up.
16:01 < yebyen> with no adornments
16:01 < manveru> Eko: but that affects the performance
16:02 < manveru> yebyen: that only works for strings
16:02 < manveru> Println is nice because it uses the ...interface{} thingy
16:02 < yebyen> import "fmt"; var dbg=func(d interface{}) {...}
16:02 < manveru> which is kinda hard to wrap
16:02 < Eko> then make a func(f string, a ...interface{}) { fmt.Printf(fmt,
a) }
16:03 < Eko> er
16:03 < Eko> f,a
16:03 < yebyen> ...interface{} is really the syntax for that?
16:03 < yebyen> does it come back in an array of interface{}
16:03 < Eko> yep.  and it can be passed straight back into the fmt.*print*
functions
16:03 < yebyen> i know my professor had a pack of slides that explained how
to use ...
16:04 < yebyen> you need to know about reflection if you plan to do anything
with the contents of that array?
16:04 < yebyen> or just type assertion
16:04 < Eko> I'm not actually sure how to use the value that you get out of
...interface{}, I just know I can pass it to the fmt commands lol
16:04 < manveru> it's type []interface{}
16:04 < yebyen> and switch .(type)
16:04 < manveru> so you can range and use reflect
16:04 < manveru> which is what fmt does
16:04 < Eko> I figured as much; it's just never come up.
16:05 < yebyen> yeah you probably don't try to write code like that
16:05 < manveru> heh
16:05 < yebyen> generally
16:05 < Eko> I've been coding Go for 48 hours now and am really, really
enjoying it.
16:05 < yebyen> types are good
16:05 < Eko> it's got all of my favorite aspects of C, Java, and Ruby.
16:05 < yebyen> i would like to chat with a ruby person about ruby
16:06 < yebyen> i've been coding go for 11 weeks
16:06 < manveru> i have code like this: http://paste.pocoo.org/show/218115/
16:06 < Eko> and as for the performance hit of having a dedicated logger,
manveru, with a language whose inner loop time is 10% off of C, I don't really
worry about the performance hit of having debuggable code.
16:06 < yebyen> and it seems like it doesn't have half as many fancy tricks
as ruby
16:07 < Eko> it doesn't have as many fancy tricks, but it has closures and
another neat data structure (channels) that let you do a lot of really neat things

the wrong way because it's still pretty raw
16:09 < Eko> I've always liked it a little rough ;)

place, and it's not as a general purpose programming language
16:11 < ThunderChicken> Heh.

19:43 < Eko> what happens if a channel has multiple listeners and you <-
something into it?
19:48 < exch> first come, first serve I suppose
19:49 < Eko> that wouldn't happen to be specific to, for instance, NOT
signal.Incoming?  >_<
19:50 < Eko> I'm trying to figure out exactly how signal dispatching works,
as I am trapping a signal in my read loop and my main loop appears to be dying
before it notices that the read loop is telling it it's over (different packages,
different goroutines)
19:51 < exch> it's a channel :p So if something reads from it, it no longer
yields said signal to any subsequent readers
19:51 < exch> which one may get that signal is prolly unpredictable

21:45 < KirkMcDonald> Let's say I have two goroutines which both have a
reference to the same slice.
21:46 < KirkMcDonald> The slice is a slice of pointers.
21:46 < KirkMcDonald> One of the goroutines iterates over the slice
repeatedly, doing stuff with each element.
21:47 < KirkMcDonald> The other periodically reassigns specific elements of
the slice.
21:47 < KirkMcDonald> Is that assignment atomic?  Do I require an explicit
mutex?
21:48 < jessta> KirkMcDonald: have you read,
http://golang.org/doc/go_mem.html
21:48 <+iant> the assignment is not atomic, and you do need an explicit
mutex
21:48 < KirkMcDonald> Thank you.
21:49 < Ginto8> pointer copying isn't atomic?  interesting
21:49 < Ginto8> I thought pointers were word-size
21:49 <+iant> they are, and if you want to rely on processor behaviour you
can
21:49 < Ginto8> oh
21:49 <+iant> but Go does not do any explicit memory lock operations
21:50 < Ginto8> it just can't be guaranteed that it's atomic?
21:50 <+iant> we may have a "very safe" mode at some point which makes those
operation atomic
21:50 < Ginto8> one of those "it might be on some systems, might not be on
others" sort of thing?
21:50 <+iant> right
21:51 < KirkMcDonald> So it will be atomic on (say) x86, but correct code
will use an explicit mutex.
21:51 < Ginto8> yes
21:51 <+iant> yes, for some definition of atomic; on an SMP system different
processors can see inconsistent data
21:51 <+iant> that is, inconsistent ordering of changes to the data
21:51 < Ginto8> yep
21:51 <+iant> which may not matter for your use case
21:52 < KirkMcDonald> It doesn't, in this case.
21:52 < Ginto8> channels may or may not work better than a slice in your
case
21:52 < KirkMcDonald> Ginto8: They won't.
21:52 < Ginto8> ok then
21:52 < KirkMcDonald> I require random access.
21:52 < Ginto8> well take a look at RWMutex
21:52 < Ginto8> more flexible than normal Mutex
21:54 < KirkMcDonald> I don't think I require that flexibility.
21:54 < KirkMcDonald> There is precisely one reader, and precisely one
writer.
