Top Language Skills

Check out this item on eWeek: Java, C, C++: Top Programming Languages for 2011 - Application Development - News & Reviews - eWeek.com.

The presentation starts with Java, C, C++, C# -- not surprising. These are clearly the most popular programming languages. These seem to be the first choice made by many organizations.

In some cases, it's also the last choice. Many places are simply "All C#" or "All Java" without any further thought. This parallels the "All COBOL" mentality that was so pervasive when I started my career. The "All Singing-All Dancing-All One Language" folks find the most shattering disruptions when their business is eclipsed by competitors with language and platform as a technical edge.

The next tier of languages starts with JavaScript, which is expected. Just about every web site in common use has some JavaScript somewhere. Browsers being what they are, there's really no viable alternative.

Weirdly, Perl is 6th. I say weirdly because the TIOBE Programming Community Index puts Perl much further down the popularity list.

PHP is next. Not surprising.

Visual Basic weighs in above Python. Being above Python is less weird than seeing Perl in 6th place. This position is closer to the TIOBE index. It is distressing to think that VB is still so wildly popular. I'm not sure what VB's strong suit is. C# seems to have every possible advantage over VB. Yet, there it is.

Python and Ruby are the next two. Again, this is more-or-less in the order I expected to see them. This is is the second tier of languages: really popular, but not in the same league as Java or one of the innumerable C variants.

After this, they list Objective-C as number 11. This language is tied to Apple's iOS and MacOS platforms, so it's popularity (like C# and VB) is driven in part by platform popularity.

Third Tier

Once we get past the top 10 Java/C/C++/C#/Objective C and PHP/Python/Perl/Ruby/Javascript tier, we get into a third realm of languages that are less popular, but still garnering a large community of users.

ActionScript. A little bit surprising. But -- really -- it fills the same client-side niche as JavaScript, so this makes sense. Further, almost all ActionScript-powered pages will also have a little bit of JavaScript to help launch things smoothly.

Now we're into interesting -- "perhaps I should learn this next" -- languages: Groovy, Go, Scala, Erlang, Clojure and F#. Notable by their absence are Haskell, Lua and Lisp. These seem like languages to learn in order to grab the good ideas that make them both popular and distinctive from Java or Python.

Programming Language Popularity -- Update

I used to rely on the TIOBE Software Programming Community Index.

Today, I learned about the langpop site. The context was following an SD Times blog posting on Haskell. But I got distracted looking at language rankings and what it means to consulting companies.

[Until corrected, I was] particularly drawn to langpop's Amazon listing. It seems like everyone wants books on C, C++ and C#. All other languages are also-rans. Why? [I guessed] that it's because those languages are so (a) hard to work with and (b) are perceived as "old school" where print resources are more prevalent than on-line resources. [Turns out the rankings are screwed up. Dang.]

Marketplace

The langpop aggregate ranking is C, Java, C++, PHP, JavaScript, C# and Python. The TIOBE Community Index is Java, C, C++, PHP, VB, C#, Python.

Similar enough to confirm that a half-dozen languages dominate with two others fighting for position.

Years ago, one of our senior consultants made the case that we really have three fundamental tech-stacks into which our web services had to fit: VB/.Net, C#/.Net, and Java. Corporate IT doesn't demand a lot of PHP or Python from us.

Perhaps those are opportunities for growth. Or perhaps there isn't enough corporate IT demand for those frameworks.
