The Most Important Obscure Languages?

Posted by samzenpus on from the never-heard-of-it dept.

Nerval's Lobster writes: If you're a programmer, you're knowledgeable about "big" languages such as Java and C++. But what about those little-known languages you only hear about occasionally? Which ones have an impact on the world that belies their obscurity? Erlang (used in high-performance, parallel systems) springs immediately to mind, as does R, which is relied upon my mathematicians and analysts to crunch all sorts of data. But surely there are a handful of others, used only by a subset of people, that nonetheless inform large and important platforms that lots of people rely upon... without realizing what they owe to a language that few have ever heard of.

  1. Does Ada count as 'little known'? by david.emery · · Score: 5, Insightful

    Most contemporary aircraft have significant amounts of flight-critical software in Ada, some train control systems use Ada, some air traffic control systems use Ada, and of course there's a lot of Ada in US (and other country's) weapon systems. There's the SPARK subset that has been used for provably correct systems (does your software vendor provide a no-bugs warranty?). And there's production-quality code available under Open Source. http://www.adacore.com/ (no connection with AdaCore, other than I have lots of friends who work there.) All of my production code after 1980 was written in Ada. There's substantial anecdotal/unpublished evidence that shows large Ada systems have substantially lower life-cycle/software maintenance costs. Your Mileage May Vary, of course.

  2. C++, hands down by DoofusOfDeath · · Score: 5, Insightful

    I use C++ all day, every day. Every time the C++ standardization committee meets, the language gets more obscure to me.
