RobotWisdom asks: "Has anyone run across (or even heard of) an up-to-date overview of the most-important new subdomains for software applications? Inspired by the popularity of my timeline of Unix/Linux, for the last few months I've been working on a new timeline of AI, simulations, and knowledge-representation in general. Digging around online for links about simulation, for example, I discovered vast areas I was completely unaware of, mostly oriented towards the US military. In another context, I started noticing the TLAs 'SCM' and 'CRM' in relation to business software, and had to trackdown what they were all about. This morning I clicked on a banner ad for 'ModelSim' and discovered the TLAs 'HDL' and 'RTL' for simulating logic-chips. Another recent news item led me to the burgeoning field of medical simulations. But what I'm not getting is any sense of an overview of all these specialized domains, that seem to have emerged in software only in the last 30 years. Are there university classes that deal with this, giving a capsule portrait of each one? Textbooks?? Webpages???"
