Ask Slashdot: What's New In Legacy Languages? 247

First time accepted submitter liquiddark writes "I was listening to a younger coworker talk to someone the other day about legacy technologies, and he mentioned .NET as a specific example. It got me thinking — what technologies are passing from the upstart and/or mainstream phases into the world of legacy technology? What tech are you working with now that you hope to retire in the next few years? What will you replace it with?"

    I've been playing with computers since the mid-70's and one of the things that I did early on was learn to program in C.

    One of the smartest things I've ever done; it's up there with my decision to start running Linux in the late 90's.

    If you can program in C you can write a program that runs on pretty much everything that you'll come across that you might want to program.

    Learn C if you want to learn a programming language that you can use for a very long time.

    I like Android, got an Android phone and a couple of tablets, but the C NDK doesn't allow you to do things without having to jump through a bunch of Java hoops to get there. I would have more Android devices if it was easier to write a program on it in C.

    Apparently the writer of the original article thinks "legacy" means that you have to maintain and enhance existing applications instead of developing new ones.

    To me, "legacy" means that there are no new applications being developed in that language, and the only jobs available for it are maintaining and enhancing existing applications. .Net and Java are certainly not "legacy" in that sense by any stretch of the imagination.

      Multisyllabic and euphemistic, I'm sure it first came into being from the lips of an advertiser.

    I'm mid-career, and this question feels very relevant to me. For the past 15 years or so, I've focused on cross-platform (mostly Linux) C++ programming, with a decent SQL understanding as well.

    But lately, the market for straight-up C++ Linux jobs seems to be waning. For one thing, more dynamic / introspective languages such as Java, Python, Javascript, and C# seem far more prevalent than my loved/hated C++.

    But a bigger trend seems to be a shift to frameworks, rather than languages + OS's, as the focus of job-posting requirements. It's no longer true that C++/Java + Linux + SQL experience lets me quickly find a well-paying job in the city of my choice. For that, one also (or instead?) needs competence in something like Hadoop, Cassandra, Ruby on Rails, Amazon Web Services, Django, etc.

    This makes sense, as CPU's get faster, and as software development continues shifting to a more connected, more web-oriented world. But it's a little scary for someone like me, whose day job doesn't offer much opportunity to work with those newer frameworks in order to develop a marketable level of skill.

    I'm guessing this is a periodic problem. Ace mainframe programmers found themselves less marketable when desktop development became popular. Desktop developers were partially outmoded by client/server, and have a more serious marketability problem now that most development is aimed at (ultimately) web browsers. It's not that serious C++/Linux/back-end geeks like me can't find work, it's just that I(we) feel a little trapped compared to those whose skills are currently in broader demand.

    I guess the question, then, is do I(we) double-down on our current expertise and become indispensable in a small fraction of the job market, or do we accept the pros and cons of partially re-inventing our careers (and setting back our salaries) to retool?

    • my good man...your confusing what's trendy with what's tried and true.

      As someone who has been in the field for about 30 years now, and can still easily find work in spite of how everyone claims IT is ageist... I think I can answer this for you long term.

      Always be learning.

      Seriously, you always need to be re-inventing yourself, studying and working to stay at the edge of the curve. Whatever is being done now will turn old (and then new again and then old again...) and you better have some way of dealing with it.
      However, you do not need to take a pay cut to do so. Start learning Ruby on a personal project. Then get a side gig converting some existing applications to web enabled ruby. Now you have the creds to demand a hell of a lot more than the 20 year old ruby guy because you can actually understand what the have, and fuse them together. All the new guy can do it burn it all down and start over. This has real value to a lot of businesses.

      And the fact that at 40+ you have a long list of skills but have stayed current with the latest stuff as well really makes you stand out on your resume.

    • Wait, you're saying there was a market for C++ Linux jobs at some point? If you want to use Linux and be the most marketable as a developer you develop in Java (with a little JavaScript sprinkled in). If you want to stay more low-level have you looked at getting into the embedded space?

    • The jobs are shifting to introspective languages because the way people work with computers is shifting from the desktop to the web. It only tangentially has anything to do with the speed of computers. There's just not as much call for desktop programs anymore because the shift has moved to a networked world that isn't tied to a desktop machine running (OS-whatever). My guess is that you'll still have a job in desktop apps programming in C++ for 20 years at least, but the world will change under your fee

    Though I'm not usually dealing with Microsoft platforms, I have enough experience with it to consider classifying it as 'legacy' in any sort of universal way an odd proposition. It is after all *the* first-party supported development framework for Microsoft platforms, very much continuing to be supported and developed by a pretty important market force (like it or not).

    Of course 'Legacy' is mostly in the eye of the beholder. About the only place 'Legacy' seems to have unambiguous meaning is within a single development organization replacing/phasing out projects they control. COBOL continues to see pretty significant deployments and is actively being enhanced, though most people in the industry would consider that 'Legacy'. Similar story for Fortran. A number of languages that don't get so much 'glory' these days continue to play important roles in particular segments and continue to be developed. There are those that would consider PHP 'legacy' and others just moving onto the platform. If you try to name a platform that by popular opinion is almost certainly totally 'Legacy' you'll probably discover not only some groups doing new development in the language, but some companies or projects actually continuing to enhance the language for others. Basically, if you can remember it, it by some definition is probably still alive.
