Hi all,

Recently, in an IFAC conf (Automatic!) in Sibiu (Romania), I was quite 
suprised to see on the proceedings a paper where some names were 
familiar to me... squeak, seaside, kom, goods..... I went and see the 
presentation of Ion MIRONESCU who I find has made an impressive job as 
part of his phd...

He made an open-source SCADA tool (/Supervisory Control And Data 
Acquisition /http://en.wikipedia.org/wiki/SCADA) based on seaside and 
squeak. He especially uses Asteroid (for reverse AJAX, COMET), GOODS for 
the backend, and SVG to get a fancy user interface. Machine data are 
generated by a PLC proxy (written in C++) and written in GOODS. The web 
interface is updated  (by comet/asteroid). The web interface also allows 
to update the database.

I found the whole app very interesting especially for the whole 
integration aspect. As far as I know, his apps works well. He has only 
cache problem leading to some update problems ("at data production rate 
(2s-1), the browser began to miss update events  or to delay their 

I told him ESUG and squeakers/seasiders will be grateful to see such an 
application ;)... Ion is about to present his phd and after (one month), 
he will polish and comment the code before publishing it. He will send 
me a paper that I'll join to another e-mail for those interested.
