This is one of the best statements I have seen. Moreover, after spending some time in the mixed SW/HW environment, I would = never assume engineers from other domains to be less competent than softwar= e engineers. On the contrary, I'm happy they they actually do not share our= anti-practices and general disregard to work rigor, of which I have seen t= oo much in software already. Note also that software engineering world, especially in the industrial and= critical domains, is slowly (?) drifting towards model-based techniques. N= ot only in some sense we are catching up with the culture that our colleagu= es from other domains cultivated long before us, but it actually makes the = advantages of Ada increasingly irrelevant. The choice will be no longer bet= ween C and Ada, but rather between Python (or similar) and Simulink (or sim= ilar - I'm referring to mindsets, not the actual products). > The PLC is not at primitive beast. [...] I very much prefer properly designed PLC solution than some random crap dis= guised as source code, even in the best of languages. --=20 Maciej Sobczak * http://www.inspirel.com
