"Clinical Trials" For Programming Languages? 232

Posted by samzenpus from the apples-and-oranges dept.
theodp writes "High school junior Charles Dawson's New Year resolution is to write a new program in different language each week. It's an ambitious project for someone of any age, and while it won't give him an in-depth appreciation of programming language differences, it'll certainly give him greater insight into the strengths of certain languages than would perusing the Hello World Wikipedia article. Lots of claims are made about the comparative productivity of programming languages, but have there been any landmark studies that measure the efficacy of a programming language's productivity claims in a 'clinical trial' of sorts? Would head-to-head tests against other languages be a better way of sorting out Popularity vs Productivity vs Performance claims, or is relying on more nebulous claims of superiority the best we can do?"

      long flamewar

      To do this flamewar properly little Charlie Dawson should post his findings every week so we can keep this thing going until he finally realizes his dream of pissing off every programmer.

    • It shouldn't be a flame war. In order to make a meaningful comparison between two programming languages I think you need to have a high level of skill in each, and write two feature-equivalent non-trivial programs in each.

      Most of the flame wars are between people who don't have good expertise in at least one of the languages under discussion, arguing about merits and drawbacks in simple programs.

      I think what Charles Dawnson plans will be interesting, educational, and fun, but you can't become good enough in a language in a week to have a useful opinion on its effectiveness at creating the next social network, operating system kernel, C compiler, web browser, search engine or office suite.

        The real problem is that different languages are often created to solve different problems. You can't really compare them very easily with any single program, no matter what non-trivial program that you use. For example, C is a better programming language than Javascript for some problems; Javascript might be better than C for some other problems.

        I'm advanced to expert in about six languages and have decent experience in a dozen others. I've settled on about four that I use a lot, and that fit the kinds of problems that I work on. Other equally skilled and experienced programmers (programming for over 40 years) would choose a different set of languages better suited to solving the problems they routinely work on.

        It's kind of like trying to compare the toolbox of a plumber with the toolbox of a mechanic. There is overlap of course but there are also specialized tools.

      As for productivity, that's harder since this is highly subjective. While you can generally postulate that coding in non typed scripting languages where you don't have to worry about memory management is going to be faster than coding in a typed, manually memory managed language like C. But what happens when you compare more similar languages like Python vs. Perl? Your productivity in a language is highly dependent on your experience with it, how fast you are at typing, how intuitive the syntax is to you.... etc... But different programmers can have different issues with languages. In Perl for example the syntactic freedom can actually lead some programmers to write bugs bugs into their code because they are used to languages with a more nailed down syntax.

        Productivity is a tough one, but it's by far the most important. That's what we get paid for.

        A good competition might be to start with a functional test, and just let developers "swing away" at it. Or you might add real world constraints that development organizations want to see, such as requiring 95%+ code coverage with unit tests, keeping complexity below 12, and it must pass lint / pmd / fxcop / other static code analysis tool with no warnings or errors. Maybe it has to pass a code review, too. The functional test would have to pass ensuring it does what it's supposed to do, and maybe it would need to pass a fuzz test to ensure it doesn't break under strain.

        And you would need to run different contests for different categories: web apps, services, operating systems, embedded systems, phone apps, etc. Not all problems are created equal.

        Terrific suggestion regarding Debian benchmark!

        There are some pretty good stats on productivity from Cocomo II group: http://csse.usc.edu/csse/research/COCOMOII/cocomo_main.html [usc.edu]. First off you measure in terms of normalized lines of code which ends up being close to the same across languages. From there you can examine how large programs are in varieties of languages in terms of normalized lines of code and you get productivity measures:

        Assembly .4
        C 1
        COBOL 1.5
        C# 2.5
        Java 2.5
        Visual Basic 4.5
        Perl 6
        SQL 10

        etc...

        Perl vs. Python for relatively similar levels of experience I'd assume the differences in productivity is going to be close to 0. You seem to need rather dramatic differences on high/low level scale to get much of a productivity boost. So for example C# and Java are both 2.5; Perl and Smalltak are both 6.

    1. I have work to do; and
    2. it's hard to objectively compare language merits in the short term or for trivial projects.

    I was thinking that the solution to this is to have one program that I understand very well implemented as well and completely as possible in a language that I feel proficient in, and have that be my reference. Then, over the course of a couple of weeks (a month?), re-implement the same program in the new language and strive for the implementation to be as idiomatic of the new language as possible. After all, if you're still thinking in the old language but just using the new one's syntax, what's the point?

    I feel like this would give you a lot of data to make a reasoned decision -- you can compare language features and how the implementation works in one versus the other; time to implementation (LOC, maybe?); how much of a mental shift the new language requires; the toolchain around the new language; etc.

    The answer is research is sparse in this area, but the few times it's been tried (using competent programmers in each language rather than conflating learning the language and productivity in it), is LISP and LISP-like languages win [norvig.com] when measuring programmer productivity and ability to express complex algorithms in small amounts of code, and C and C++ like languages win for ultimate ability to make the program run fast. But the variability from programmer to programmer in how fast the program runs can exceed the variability between languages so it pays to get high quality programmers who have an intimate understanding of both efficient algorithms and the underlying machine architecture, rather than think "the language will make the program run fast".

One problem (if I remember correctly) was that the different programs, written by different people, in the same, or same type of, language often failed on the same or similar edge cases.

    The experiment was to implement the same solution to a problem using much different languages. In this case, Pascal and Prolog. The "gold" Pascal routine was already written and my task was to write the corresponding "gold" routine in Prolog. [ I also did work for a related study in the automatic analysis (and execution) of abstract data types in LISP.] I graduated before the experiment was run, but found the idea as least plausible.

    Note that I might be remembering some of this incorrectly as it was a while ago and I was only an undergrad. (They wanted a graduate student, but I was the only one with LISP and Prolog experience... And $9.50/hour wasn't bad for 1985.)

    In the real world, you pick the right tool for the job. You never pick a language because it's the best language. There is no such thing. Factors going into language selection where technical merit plays no role include what the other developers at the company and/or the project are using, what environment you're using (if Apple, then Objective C; if Android, then Java), what language the code you are maintaining was written in 5, 10, 20, or 30 years ago, and (hopefully if you are a great programmer this will be a minor issue) what languages you're comfortable with using.

    After 30 years I've learned that basic computer science concepts are helpful, but only to a point. Google may want you to know specifics about certain types of trees for their interview process, but if you need to know that level of detail for a job, you spend a few hours on Google and learn it. The same goes for languages. Figure out what you need with a bit of research before you start the job. You should have a great idea of what environments a language is nearly always used, so you don't try to do something weird nobody can maintain. If you're going to write an iPhone app, you're going to adhere to whatever specific Objective C thing Apple is doing. Maybe I'm slightly out of date and Apple is doing something else, who knows? I don't work in that space.

    Python everywhere, be damned with you, is a quick way to make enemies of people 10-20 years down the road who have to maintain your code. I was doing web development in the 1990s, and everybody used Perl. For everything. Now I work with a legacy Perl code base, and mod_perl seems to be completely abandoned, and it certainly hasn't been released for apache httpd 2.4 yet. We're using Perl because we have to, but not for new stuff. But for the Perl part of our system in bug fix maintenance mode, it is the appropriate language. We didn't have the attitude that we'd continue to use Perl for everything just because that's the way things were done. We were flexible enough to slowly switch over to PHP for certain things that we had been using Perl for.

    Avoid fads like the plague. After 30 years of programming, I just ignore marketing. I have no gee whiz attitude about anything. I focus on perfecting my craft, learning how to program better, to debug better, to test better. Learning how to deliver code that works now and five years from now. All that is way more important than figuring how how some language is subjectively the best.

      I'm not sure I would generalize too much from Perl. Perl had a terrific run going from a text processing language to a system admin language to the standard for web development. Then it moved towards applications development. And then it faltered badly. They responded to the faltering with an overly ambitious and poorly managed next version which has sucked the life out of the language.

      Perl is an example of picking a technology that died. Lots of people who have picked lots of technologies they thought

        Python is in the middle of a 'next-version' crisis, too.

      Half of /. are Java haters, nevertheless many of those work with Java. The other half are C# haters but nevertheless work with .Net/C#
      The rest are Python and Perl lovers, but work with C/C++
      AFAICT: there is no real world. There are only plenty of dream worlds. It is up to you if your dream world is occupied/ruled by a nightmare.

    • ...Google may want you to know specifics about certain types of trees for their interview process, but if you need to know that level of detail for a job, you spend a few hours on Google and learn it....

      These types of questions are finding out your breadth and depth of knowledge about data structures and algorithms. No, you cannot become proficient in this area in a few hours. You need reasonable proficiency to even be able to intelligently Google the appropriate specific knowledge. I find that knowledge of data structures and algorithms is essential for being a competent programmer.

    Hi everyone. Thanks for all of your comments. I just want to quickly elaborate on why I'm doing this and what I'm trying to do with this project: I am not trying to start a flamewar, annoy programmers, or hog attention. I am not aiming to master any of these languages after only a week. I'm not even trying to get "okay" at any of them. All I'm trying to get out of this project is a more broad understanding of the languages that are out there, and what, in a very general sense, each language is good for. My thought is that if I can get even one cool new idea or concept out of each week's programming language (like functional programming concepts from this week's foray into Haskell), I'll consider this project a success. Also, it will allow me in future to be able to quickly reference a new language if I need it for something I'm working on (not necessarily remember any syntax or anything, but at least to save myself some googling time). Thanks for your interest. Sincerely, Charles Dawson

    • If understand correctly: 52 projects in 52 languages in 52 weeks? A high school junior? You're nuts for even trying this.

      I like that. :) Good luck, have fun, and I hope you learn a lot. We each have our ways of learning programming and this seems like an interesting way to do it.

      • Using a week to learn a language and do a small project on it isn't that crazy. The problem is just that after week 30 or so, you start to run out of sane and useful languages (unless you dig into the obscure) and end up experimenting with brainf**k.

    • Yepp, welcome!
      However you could have googled for your questions rather than asking here and claiming in your question that there never has been any study.
      The world is full with studies about various languages or concepts since ... hm roughly 1965 (yes, 1965, not only 1985)

  • We all know innately know this, but sometimes it's hard to avoid getting caught up in a religious debate about the apples-to-oranges details.

    Once your language is at least complex enough to write a compiler or interpreter for itself - that is, it's no longer a toy language - it tends to be more or less capable of everything every other language is capable of. Sure, it might not be the best tool for a given job, but they're all generally the same aside from some syntactic sugar.

    • Thank you. It's like asking what language should diplomats use to negotiate a peace. Obviously, the most productive language is the one in which people are extremely competent and comfortable using...until they need to describe the the 27 types of snow, in which case they can switch from a European language to an Eskimo language to better express the concept. I assert a language's strengths and weaknesses for an idealized problem are trivial...compared to the strengths and weaknesses of the individuals
