Re: [Newbies] Sound, video and color in morphic projects - Beginners

30 Apr 2020

      Hi,
I am Ricardo Salvador,  and i am writing because i found the solution to
one of the problems i asked for help about; maybe this will help someone
else.
It's about sound playing. In ubuntu the sound was not played in morphic
projects and in the terminal I got the message "sound: /dev/dsp: No such
file or directory".
Since the "/dev/dsp" folder is part of the Open Sound System (which has not
been included in Ubuntu for a long time), for Squeak to find it, it was
resolved by installing "osspd" a package that emulates a daemon needed to
make the "/dev/dsp" folder available.
Greetings!

Hello!
I'm Ricardo Salvador, from Rosario, Argentina.
In 2008 I met Squeak-Etoys and was fascinated by it. Since then I use it in
high school; I've been testing Squeak 5.x for a while and now with version
6.0: working with morphic-based projects is a fascinating and at the same
time friendly way to start teens in programming.
And in my experience I see that Squeak is really simple to learn with OOP
principles. Now I try to learn SmallTalk.
That's why I want to make a contribution-questions about Squeak 5.3 and/or
6.0 alpha:

On Linux Ubuntu 18.04 no sounds are played: when I try, the console

gives the message "sound: /dev/dsp: No such file or directory". I haven't
found a solution yet. In Windows it works.

The "Color" category is missing, containing the tiles "red", "green",

"blue", "hue", "brightness", "saturation". The first three are very useful!

I can't get the camera monitor to work on Linux or Windows. On Linux I

don't get any feedback from the camera.
Those features still work ok in Etoys 5.0 although of course I would like
to change to a current version of Squeak for its performance and validity
improvements.
I'm a teacher, specialized in computer technology applied to education. If
I can contribute in other ways, I'm at your disposal.
Thanks in advance!
