An anonymous reader writes: Many years ago, I was a coder—but I went through my computer science major when they were being taught in Lisp and C. These days I work in other areas, but often need to code up quick data processing solutions or interstitial applications. Doing this in C now feels archaic and overly difficult and text-based. Most of the time I now end up doing things in either Unix shell scripting (bash and grep/sed/awk/bc/etc.) or PHP. But these are showing significant age as well.
I'm no longer the young hotshot that I once was—I don't think that I could pick up an entire language in a couple of hours with just a cursory reference work—yet I see lots of languages out there now that are much more popular and claim to offer various and sundry benefits.
I'm not looking to start a new career as a programmer—I already have a career—but I'd like to update my applied coding skills to take advantage of the best that software development now has to offer.
Ideally, I'd like to learn a language that has web relevance, mobile relevance, GUI desktop applications relevance, and also that can be integrated into command-line workflows for data processing—a language that is interpreted rather than compiled, or at least that enables rapid, quick-and-dirty development, since I'm not developing codebases for clients or for the general software marketplace, but rather as one-off tools to solve a wide variety of problems, from processing large CSV dumps from databases in various ways to creating mobile applications to support field workers in one-off projects (i.e. not long-term applications that will be used for operations indefinitely, but quick solutions to a particular one-time field data collection need).
I'm tired of doing these things in bash or as web apps using PHP and responsive CSS, because I know they can be done better using more current best-of-breed technologies. Unfortunately, I'm also severely strapped for time—I'm not officially a coder or anything near it; I just need to code to get my real stuff done and can't afford to spend much time researching/studying multiple alternatives. I need the time that I invest in this learning to count.
Others have recommended Python, Lua, Javascript+Node, and Ruby, but I thought I'd ask the Slashdot crowd: If you had to recommend just one language for rapid tool development (not for the development of software products as such—a language/platform to produce means, not ends) with the best balance of convenience, performance, and platform coverage (Windows, Mac, Unix, Web, Mobile, etc.) what would you recommend, and why?
