 I know that the population of 9fans contains a sizeable percentage of
 people who would like to cast Plan 9 in amber, to hold it immutable as
 an example to future generations.  That's an unrealistic expectation.

Maybe, but maybe that's the best we can do, given that the conditions
that gave rise to Plan 9 have long ceased to exist and are unlikely to
recur.  A version of Plan 9 untainted by the predominance of the Intel
and Windows philosophies is needed to reminds us of how things could
have turned out.

But it is all much more complex than a mailing list could possibly
track.  Since the 1970s, it is clear that technology has taken a
number of quantum leaps that could have landed in different places and
all the missed opportunities, good and bad, need to be recorded as
well as explored because we sure as hell are not in the best of all
possible futures, right now.  Unless you're some virtual entity such
as Microsoft, Intel, Google or Facebook and could not care less about
the fate of individuals.

 binaries are bigger and for example replacing the minimal sets of commands of

 if that was a real issue you were trying to solve there are things you
 can do to help yourself. most notably sticking everything in a single
 binary and invoking the right function based on your argv0. it took me
 less than 15 minutes to convert the above code to work as a single
 binary and most of that was in handling clashing flags (it would've
 been a non-issue if I had used flagsets when writing the original
 programs). size at the very end:

 $ du -k $GOPATH/bin/all
 1888 /Users/andrey/bin/all
 
 the size of the original binaries on plan9 is 588k. what was a factor
 of 30 is now a factor of 3. all tests still pass and it took less time
 to complete than writing this email.
 
 there's an even better solution, but it won't work on plan9 because

I am intrigued by go but I mostly write embedded code for a day job
and I believe go doesn't really cover that space well. The other
part of my job is image processing which would be apropriate for Go
but my employer has mandated c++ so that is the end of that.

I do have a few honest questions about the current state of Go.

Is there a standardised GUI binding for go, somthing cross-platform?

Is there any concensus as go could be used  on bare metal or is that
just un-realistic given garbage collection and the relatively large
runtime.

has there been discussion on how some of the runtime could be moved into

Re: [9fans] gcc not an option for Plan9

2013-03-24 Thread lucio

All below is opinion, possibly uninformed.

 Is there a standardised GUI binding for go, somthing cross-platform?
 
Not yet, although I think the pressure is building.  At the moment,
from where I am, it seems that a lot of development relies on
interfacing with a web browser and there are a few specialised
packages that interface with the conventional Unix toolkits (GTK,
etc.).  These last are not, in my opinion, cross-platform (enough).

 Is there any concensus as go could be used  on bare metal or is that
 just un-realistic given garbage collection and the relatively large
 runtime.
 
I have seen no sign of this, but here I think Rob is right, the
hardware is moving into the cross-hairs, rather than Go bend over to
it.  The ARM A13 and A10 as well as the AVRs have shown that big CPU
feature footprint does not have to mean a big physical footprint.
Maybe the contrary applies.  The GPUs puzzle me in this context, but
I'm not sure how relevant they are.

 has there been discussion on how some of the runtime could be moved into
 a go-specific OS - would that even be a good/interesting idea?
 
It's something that struck me recently too.  Go as it stands is not
ideal for operating system development and there has been discussion
of how the runtime and especially the garbage collector could be
redesigned for bare metal, but I think the demand needs to become more
shrill before the design can become more than just a concept.

Re: [9fans] gcc not an option for Plan9

2013-03-24 Thread tlaronde
To go back to the original subject, since gcc(1) has taken the C++ path,
I will be more than happy of an increase of Go programs since, thanks to
the work of some people, Go for Plan9 is possible.

As for the Go language, it is sufficiently near C, with extensions that
feel natural, to be interesting and easy to grasp for a C programmer
(and the gotour allows to start easily).

But it is the same as some parts of mathematics: I was not really
interested in them because they were not in the neighborhood of
what I was interested in at the moment. I finally got interested
in these parts later, when my wandering suddenly arrived in these
neglected parts, reminding me something (and then I saw why it
was interesting). So Go is stocked in a part of my mind, perhaps
simply waiting for a problem it will be the tool to solve.

But since I'm one of the few who use litterate programming (cweb), I
would probably start by wrinting a goweb instead of using the dedicated
tools...

[9fans] gcc not an option for Plan9

2013-03-23 Thread tlaronde
There are, regularly, mention for porting or having gcc(1) on Plan9 in
order to be able to port more user level applications (because user
level applications not only depend on a bunch of things---generally
ignoring standards---but on compiler idiosynchrasies too...).

With gcc 4.8.0, the implementation of gcc is now in C++... And to
compile a compiler, one needs a C++ compiler...

Great! I always thought that, because of what can be embedded in a
compiler (cf. Ken Thompson's Trusting Trust) and because of a
bootstrapping process (as explained in the red dragon book for example),
the compiling of a compiler should need the strict minimum...

IMHO, with the advent of a crisis compared to which 1929 will be a
minor storm, there will be a general disgust and lack of trust and a
return for crucial things to small is beautiful (and safer).

Plan9 is not dead, simply waiting its finest hour. Gcc on Plan9 is. 
And I won't weep.

I wouldn't cry too many tears over GCC.  Having investigated Hogan's

Hence Go, together with the upgraded (if you want to call them that)

don't see any organisation or authoritative person recommending 8c et

The obsession with optimisation, in part, is to be blamed, too.  But
not alone.

Just as a side note, I was hoping to port Plan 9 to the Olimex
LinuXino, one of many project that may or may not see the light of
day.  It comes with some or other variety of Linux, but has too little
memory (64MiB) to be more than an embedded prototyping system and the

The other industrial strength open source c/c++ compiler clang/llvm is also

I think Plan 9 spoils us, the OS is just a tool, not a faith.  Just as
Go is not a faith, just a logical evolution of Alef, through Limbo, to
the platforms and conditions that prevail today.  What matters is to
be able to produce code that runs on useful platforms and does not
require blood, sweat and tears to be made to work.  Myself, I want to
teach underprivileged kids to program, the OS platform of choice is
Plan 9, but I also need to prepare them for the Windows, Linux and OSX

Can we conclude that the added power is lost for the result obtained

a washing powder giving already a perfect result 20 years ago had been
improved (from perfect to more than perfect) being able to give a
perfect result even if you make a knot around the heavy dirt before
throwing in the washing-machine: you have a perfectly clean result (as
you could obtain before, but without making the knot), except that
you have to make the knots before and try to unmake them after?

I remember when I started to work in a surveyor office. There was
microstation, back in early 90s, that ran on a DOS extender with a 
perfect graphical performance (you were able to work flawlessly, 
zooming, panning or whatever). You were never waiting for the
application or the display; it worked faster than your input.

Once Windows improved came, it took several years for the computers to
give the very same user experience, by an order of magnitude increase in
power for the PC. It had to recover from Windows improvements first...

The funny thing is that the compilers seem to be really fast, but the go tool

Also, doing a cp /bin/echo /bin/hg improves things a bit.

This is just IMHO, the language is nice as are parts of the runtime.

 I remember when I started to work in a surveyor office. There was
 microstation, back in early 90s, that ran on a DOS extender with a 
 perfect graphical performance (you were able to work flawlessly, 
 zooming, panning or whatever). You were never waiting for the
 application or the display; it worked faster than your input.
 
 Once Windows improved came, it took several years for the computers to
 give the very same user experience, by an order of magnitude increase in
 power for the PC. It had to recover from Windows improvements first...

yes.  this is a big problem.  incremental improvement often fails.
and we see this today with newer phones performing poorly with
new and improved software.

the way to get out of this trap is to provide real improvement
by doing something new.  (the term of art is disruptive—a
rather annoying term. :-)) obviously the new approach isn't going
to be as polished as the old approach.  but if the new thing
is a real improvement, folks will put up with the regressions
in unimportant areas.

there was an old way to say this, you can't make an omlette

2013-03-23 Thread andrey mirtchovski
this is not a new discussion, it started in november 2009. the fact
that it's just coming to 9fans is a sign of how far behind the times
we are :(

the go runtime is ~380k. that one you must carry always even in an
empty program (see below). what you're complaining about is the
side-effect of importing fmt and other big packages such as os and
net. with fmt you're sucking in all the unicode code tables and the
reflection code used to process printing arguments (which you can't
prove will not be used). the initial jump is big, but as your code
grows the binary size tends to increase slower -- all of the imports
are already in. the biggest program from the Go distribution
frequently in use is godoc. it deals with xml, json, binary
encoding, directory navigation, document preparation, source code
parsing, compression/decompression and serves the major website for go
-- golang.org... that program, statically linked, is 8 megs (64-bit).
i've seen things that deal with graphics which get to 20 megs. that is
reasonable, i think.

here's an illustrative progression of go binary sizes:

$ cat  t.go
package main
func main(){
}
$ go build t.go; ls -l t
-rwxr-xr-x  1 andrey  wheel  384880 Mar 23 12:43 t
$ cat  t.go
package main
func main(){
println(hello)
}
$ go build t.go; ls -l t; ./t
-rwxr-xr-x  1 andrey  wheel  389008 Mar 23 12:43 t
hello
$ cat  t.go
package main
import unicode
var _ = unicode.MaxRune
func main() {
}
$ go build t.go; ls -l t
-rwxr-xr-x  1 andrey  wheel  581024 Mar 23 12:45 t

It's pointless to complain about the size of hello world. It's not a
real program. In Go's case it's larger than a C binary because the
libraries (and the presence of a runtime) are capable of much more
under the covers, but by the time you write a real program in Go
you'll find the ratio of Go binary to C binary isn't nearly so large;
the incremental cost to the binary of a Go source file compared to a C
Go file is negligible.

 incremental improvement often fails.

why does it fail? I don't see why this has to be a rule.

a frequently annoying counterexample is when they yet again reinvent
the wheel, include a new compatible implementation of all the old
features and some new features, all based on some better design - and
most of the old bugs are gone, lots of things just work, lots of new
stuff even - but lots of stuff that used to work is now bugged also.

Re: [9fans] gcc not an option for Plan9

2013-03-23 Thread Rob Pike
For example, looking at what go install does wrt what a few mkfiles would
do for the same go source is illustrative of what I'm trying to say.

I've never seen a mkfile that builds a transitive dependency graph
given only the source code, downloads the relative dependencies from
the network, builds all the dependencies, and installs the result. Yes
mk could do that, but it would need a lot of help, and that help is
not going to materialize. Why use mk when the source code has all the
information you need to build the program?

I was a big fan of mk, and it (or make, depending) is still used to
help bootstrap the Go installation, but honestly I do not miss writing
mkfiles one bit.

with mkfiles you can never have something like http://godoc.org. in

other language without major support from the authors or volunteers.

what godoc.org does is amazing -- when you type in a query for
something that looks like a go package it will attempt to download it
and generate the package documentation from the source code on the
fly. no interaction from the author or website maintainer need to
happen, all is done by the go tool, usually with enough speed that not
much waiting is involved. all the package needs to do is abide by a
few rules in naming imports.

try it for yourself (these packages will surely not be in the index):

if that was a real issue you were trying to solve there are things you

the size of the original binaries on plan9 is 588k. what was a factor
