OK, I've read it, and clicked through to "Ancient Languages: Perl". I didn't read all of the rant, but I think I read enough to say that I agree with him completely about Perl. I used Perl with some enthusiasm for a time, but will never use it again if I can avoid it. It's just an ugly language. "There's more than one way to do it," is its curse; there are far too many ways to do anything.
I also agree to some extent about Lisp. Lisp, despite its antiquity, is still in some sense the most important programming language there is (but not in the sense of being popular). But there are too many quirky implementations of it in the wild. Its antiquity shows in the names of a couple of VERY important functions, "car" and "cdr". Incredibly, the "ar" and "dr" suffixes refer to hardware registers in a long-defunct computing system. I once wrote a partial re-implementation of Lisp in C, and for those functions I used the the names "hd" and "tl", short for "head" and "tail", which make far more sense.
Oh, there's also IronPython, not really a new language but a re-implementation of an existing one. I once downloaded it, but after a glance at the long list of differences between IronPython and standard Python, I decided it wasn't worth bothering with.
Only one I've heard of recently is the PowerShell, and that is no longer very recent. It's something Windows had needed badly for a LONG time. That it took so long for Microsoft to get around to it is an indication of Microsoft's general backwardness as a software company.
One of the first languages that I learned was Basics on MSDOS, created by Microsoft. Was it the first interpreted language? Wondering if you can still write code in basic and get it to work on a modern Windows machine. A very old MSFT language still in use is the CMD Shell.
In the context of Big Data, Excel won't disappear because it is widely used for presentations, and very interactive. But C# is not very popular, much less than Java. SQL will still be used for a while, though NoSQL is gaining some momentum. Not sure how much MSFT is investing in NoSQL technologies, I'm sure they do, as they also invest in cloud systems.
