Much of the software development discussion on HN centres on web apps — that’s where a lot of the startups and a lot of the money have been in recent years, after all — but now and then we do discuss things closer to engineering/science/mathematics. For example, a year or so back we had a discussion about geometric constraint solving in Blender¹ and it turned out that a couple of us have worked on a related library in the past.

Confidentiality permitting, if there’s anything in particular you’d like to know about developing that kind of software, I can try to answer, and maybe others will spot this and contribute as well.

Thanks. Like you said, industrial software isn't exactly on the bleeding edge or attracting lots of startup attention.

I don't have any specific questions, and I'm not necessarily interested in any single piece of industrial software. I think it would be interesting to eavesdrop on folks talking about these things.
