Hi,
As promised, here is the pdf file of Ion Mironescu about using squeak
seaside as a SCADA (Supervisory Control And Data Acquisition ) tool
written in squeak and using seaside for the HMI.
The code is open source but not published yet.
The file is named "object oriented framework for a scada hmi" from I.
Mironescu. File is ok but pictures are not perfect, anyway it's
readable. You can download it here:
http://cdrick.seasidehosting.st/resources/MironescuMCPL2007.zip.
I think it deserves a sreenshot for the user section of seaside.st ;)
Thanks Ion :)
