I am an electrical engineer whose work includes SCADA programing for
operator interfaces of industrial plants using Citect [1] and a bit of
Wonderware [2]. Both of these products include very nice sample
projects for their tutorials - which would provide a student a good
introduction to the functionality required of a HMI development tool.
What do you mean two-tier HMI? In my work, tier1 would be a PLC
containing the running control model of the plant, providing measured
values to the control logic programmed in the PLC and driving relays and
actuators. Tier2 is the HMI that provides the mimic of the PLC as a
graphical representation of the plant, colourizing warning and alarm
conditions, fill levels of tanks and allowing the operator to send
commands to the PLC to start machinery. Something doing this based in
Smalltalk would be wonderful.

So, here is the proposal:
Name: Khubbatov Rustem
Difficulty Level: Intermediate
Description
A framework for building Human-Machine Interfaces with Pharo back-end providing model, and presentation front-end in Amber.
Technical Details
A concrete task that should be implemented with this project is a prototype of
UI for network management system or SCADA. Server-side (Pharo) will simulate
network components and their data, and provide relevant events for client
(Amber). The latter will present network items, their state and associated
information, and provide UI to control them. An important part of this system
is a communication layer between Amber and Pharo.
Benefits for the Student
The student will gain experience in building client-server applications with
advanced UI and providing two-way communication between client and server.
Benefits for the Community
An ability to create highly interactive web-based applications is a must-have feature for any modern development system. Amber is a bleeding edge in this area in Smalltalk world. A good communication layer between Amber and (for example) Pharo is a very appealing decision for building complex client-server systems.

Hi Dennis,
I'd suggest to go ahead. This is first Amber-related project, so it seems even more interesting. But hurry up. Let Rustem prepare the proposal and you post here then we'll open the project page.
Best regards

Rustem Kkubbatov (http://gsoc2012.esug.org/rustem-khubbatov), another student I mentor in Tver State University, decided to try his luck with a project for GSoC. The problem is he can't currently choose a better approach.
The original idea is to build a two-tier Human-Machine Interface (HMI) system (which can be used in a wide range of projects) with Pharo image as back-end (where a model lives) and Amber-based client as a front-end. But this thing seems to be "a little bit" too large for GSoC, isn't it?
An alternative task could be to build a framework for message exchanging between Pharo and Amber. I could be the first mentor for a project based on original idea, or the second/first (depending on if anyone interested) for communication framework.
Any ideas and advices are welcome (ASAP). Thank you in advance.
Best regards,
Dennis Schetinin
