One hand is raised, the other is not. The bulk of my current professional work is Tcl/Tk and SQL for non-real-time database management portion of a simulation of integrated air defense systems. This simulation also includes lots of GUIs (Xlib and XView), and some hard real-time control of radars. Of course, being a simulation, no-one dies if we miss a deadline. But, if we produce incorrect results and some mission over Iraq fails because they used bad data, someone IS dead. Approximately 90% of the code is Ada (closer to 99% in the real-time portion). Question (to start another fun thread): is this war-fighting code? I've used Ada for both embedded systems and UIs (both graphical and text, to connect this thread with another!). I've enjoyed them both. I've built UIs in 8085 assembler, C, Tcl/Tk, and Ada. I prefer solving tough technical problems, regardless of the language, the application, the processor type, the operating system (or lack thereof) and whether it is new code or maintenance. Specifically relating to Ada and GUIs: most recently, I've used an Ada interface to XView for implementing GUIs. This was NOT fun. XView is a mess and the Ada interface was not much help. We switched to Tcl/Tk. This is primarily why I wrote TASH* so that I could use Ada instead. Unfortunately, we have not yet moved up to Ada 95, so can't use TASH! If we were starting over today, I would recommend using Aonix' ObjectAda targeted to either WinNT or Java Virtual Machine for the GUI portion. * TASH (Tcl Ada SHell) is a freely available Ada 95 interface to Tcl/Tk (also free). To connect this post to yet another thread: TASH is freely available to the Ada community and can be found at http://www.ocsystems.com/xada/tash/. It uses neither the ACL nor the GPL. Its license is based on the one that Sun uses to freely distribute Tcl/Tk.
