Web-UI for Ada applications (Was: Object Pascal vs Ada -- which is better for a hobbyist?)

The problem with this is that you both add an extra "OS" layer (the
browser) _and_ require GUI operations to be interpreted (to some extent)
rather than executed as binary code.

Use Dart (or some other event-oriented language) for the processing in
the browser.

Make the calculation (and rendering?) server available through HTTP,
pushing results over a websocket.

This way the users can push tasks from the UI to the server, and the UI
will receive the results (activating an event handler) once they are
available for display.

We are developing an application with a structure similar to this at
AdaHeads.
