If it helps, I started a minimal wrapper of the cross-platform FMOD library

mp3s.

[Werner Kassens]

let me rephrase it  just that there are no misunderstandings, 
NumericalMethods is independent of SciSmalltalk and does work in Pharo4

Perfect! Count me in. I'm not sure whether I can stay until the last

Is there anything I can read upfront? Is it just one cam or multiple

NumericalMethods should be kept separated from SciSmalltalk so we are free
to use NumericalMethods without requiring to load the whole SciSmalltalk.

I mean it would be strange that Nabble had all the Pharo user-only and
[Pharo-users] does not have any.

Or maybe there are user-only on Nabble. But I guess not so much ? Or not
more that in Pharo-users.

[Pierre CHANSON]

thanks!
Around 500, it's still impressive.

I guess I can count a little bit less to have a number on Pharo devs, Pharo
active community.

But it is difficult to put a real number on pharo users:
If we consider that all Pharo devs (or almost) are in the both lists, (And
I guess this is not so false because my feeling is that Pharo devs tend to
help new Pharo users) it means there is no Pharo user-only, or there is no
Pharo user-only in the mailing list...
And at first I would have thought that begin to use Pharo, comes with
applying to the mailing list (because there is not a lot of tutorials and
documentations for any kind of Pharo applications all arround the net).

[Xavier MESSNER]

Hi,

> "disabe pulse-audio", 
> is a good solution.

The two methods can be used. But I think the best is not to use the plugin.
If the plugin is changing and is no longer compatible with Pharo or
conversely you can no longer use this method. At the moment this is not the
case.

While there, disable pulse-audio allows you to use Pharo with no change in
its basic version. What seems to me to be less complicated in case of bugs
on the sound system.

When writing the article for Linux Magazine (a French magazine) I asked
myself this question. Should I write to use the Squeak's plugin or simply
stop Pulse-Audio?

I put myself in the place of a newcomer in Pharo who wants to use the sound
system. Install a plugin from elsewhere to run Pharo could give the image of
a not finished tool. While there, the plugin does not exist and it does not
matter because the sound works with a clear and simple method. It works out
of the box.

After that, in a near future we should have a plugin for Pulse-Audio or
best, Linux should have only one method to access sound, but it's another
story :)

thank you so much for this find!

is anyone more familiar with pharo willing to work with me on this to see if we
can get it to work?

FYI, Ian Piumarta implemented telnet with full terminal (VT102) emulation.
It uses a pty interface and thus supports mutt and text editors directly
in the image.

  http://squeakvm.org/unix/goodies.html#html/goodies.m4.2.0

It works very well and does exactly what you want, but it was written more

on Pharo.

probably the biggest reason is that the list has been quite inactive till
now. Another is that many of pharo users find it easy to contribute back to
pharo because of the nature of the enviroment and the third , the community
is just to small to have a sizable pharo-user list. Personally I am

Is interesting that we have more people in Pharo-Dev than in Pharo-Users, I

well, PipeableOSProcess is part of the CommandShell package, so i have seen it
and speculated that there was more to it, but i could not really see what else
that was. thank you for pointing me to documentation. this will help for some
of my commandline work. it won't help to run mutt, sup (the mail client i use)
or tmux though.  for those a full terminal emulator is needed.

Hi Martin,

Are you aware of CommandShell (http://wiki.squeak.org/squeak/1914)? Look for
ConfigurationOfCommandShell.

Thank you xavier.

We should discuss how to solve this. Neither "copy the squeak plugin", nor
"disabe pulse-audio",
is a good solution.

Still weird for CSV. How many record are there then ? I assume they all have 
the same number of fields ?

Anyway, could you point me to the specification of the format you want to read ?
And to the older the that you used to use ?

Thx,

Sven

I'm definitely interested in this! One of my current pet projects is 
building a RETE based inference engine in Smalltalk. It's still in 
pretty early stages though. Still,  we might have some overlap :-)

Re: [Pharo-users] Pharo Sound of Silence

[Xavier MESSNER]

Hi,

I have written a chapter which explain how to have sound in Pharo.
You can read it  here

 
.

In fact all you have to do is to disable pulse-audio to make it work.
I have tested it with ubuntu 14.04 64, ubuntu 12.04 64, OpenSuse 13.2 64,
sabayon 64 (don't remember the version) and should work for every
distributions.

I think that should work for Pharo 4, but no time to test at the moment.

Xavier.

This is defined in UIThemeWatery>>#newTaskbarThumbnailIn: aThemedMorph for:
aWindow
It looks better with the WateryTheme, because it uses a darker background.
You can:
- define your own theme as a Subclass of Pharo3Theme and overwrite this
method
- change the background(color) of the world.

Yes, sadly fogbugz does not support that.

We will move just due to this to another issue tracker eventually, but it will 
be quite some effort.
I do not yet know when we will have the time and energy to do that.

Hello,

If anyone is working in a rule engine we could merge efforts because I have
implemented one (or something like that) for a project.
