Is Ada actually used outside of the US military? I'd love to hear more, I've always thought that's where it was.
That is also VHDL, which is based on Ada, is also mostly used in Europe in detriment to Verilog.
FOSDEM tends to have a regular Ada room.
Besides military, there is avionics, transport, critical factory infrastructure, lots of stuff that falls under high integrity computing.
Alas FOSDEM has changed its room attribution scheme for 'smaller' communities and IIUC there was no Ada room this year. Hopefully there'll be a space next year.
