Re: Sound, video and color in morphic projects

Ricardo Pablo Salvador

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.

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:

1. 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.

2. The "Color" category is missing, containing the tiles "red", "green",
"blue", "hue", "brightness", "saturation". The first three are very useful!

3. 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

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!
