This list proves nothing. C++ is often used for performance reasons or even as a target language. Facebook's HipHop compiler converts PHP into C++. I would argue that it means that Facebook develops in PHP rather than C++. Similarly Adobe's most recent product Lightroom was about 63% written in Lua [1] which they attribute to its rapid development. What would be interesting is a table which shows what percentage of developers or projects predominantly develop in C++. I am guessing it would be a much smaller number.

Yes but the info is very old. I wonder if Adobe is still using it and would provide some sort of update. No Lua IDE from them as they have half promised, or anything i have seen they contribute back to Lua. Was wondering if they were using LuaJIT as well.

That's very interesting. I didn't know that about Lua and Lightroom. It's interesting for me as I'm asked a lot by photographer friends about large performance problems with Lightroom. Particularly between versions 3 and 4. Huge number of issues on the boards out there about it. I'm not saying there's a causal relationship. Still, it might be an avenue to investigate for me.

I moved to Lightroom for this very reason. Adobe also supports new Camera's RAW formats earlier than Apple. I never really peeked into the application bundle of Lightroom, but at least some of the plugins that I used were written in Lua.

    Nothing against Lightroom though. It's one of my favourite programs from Adobe, together with InDesign. And I've heard that about Aperture, and recently FCP.

Now at Facebook there are about as many C++ developers as PHP. Sounds like a shift to me... http://www.johndcook.com/blog/2012/04/11/facebook-and-cpp/ http://www.johndcook.com/blog/2012/04/11/facebook-and-cpp/

  C++ is coming back in a big way because it saves money. It is the king of performance per watt, per cycle, per transistor which directly translates to performance per dollar. It cannot be beaten. http://www.alejandrosegovia.net/2011/09/08/herb-sutters-why-c-talk-sum-up/ http://www.alejandrosegovia.net/2011/09/08/herb-sutters-why-...
