Are There More Developers Than We Think? (redmonk.com) 191

JavaScript's npm package manager reports 4 million users, doubling every year, leading to an interesting question from tech industry analyst James Governor: Just how many developers are there out there? GitHub is very well placed to know, given it's where (so much) of that development happens today. It has telemetry-based numbers, with their own skew of course, but based on usage rather than surveys or estimates. According to GitHub CEO Chris Wanstrath, "We see 20 million professional devs in the world as an estimate, from research companies. Well we have 21 million [active] users -- we can't have more users than the entire industry"...

If Github has 21 million active users, Wanstrath is right that current estimates of the size of the developer population must be far too low... Are we under-counting China, for example, given its firewalls? India continues to crank out developers at an astonishing rate. Meanwhile Africa is set for crazy growth too... You certainly can't just count computer science graduates or software industry employees anymore. These days you can't even be an astronomer without learning code, and that's going to be true of all scientific disciplines.

The analyst attributes the increasing number of developers to "the availability, accessibility and affordability of tools and learning," adding "It's pretty amazing to think that GitHub hit 5 million users in 2012, and is now at 20 million." As for the total number of all developers, he offers his own estimate at the end of the essay. "My wild assed guess would be more like 35 million."

        Not that I think you're wrong, but is this really so different to the Visual Basic or PHP "developers" of yesteryear? Maybe JS is just the latest language that everyone automatically has on their computers and where it's easy to find beginner tutorials (good, bad or otherwise) online.

        • The industry started going downhill around then ... I was not implying the industry started going downhill recently.

          I've heard folks complain about the current writing skills of Americans saying Thomas Jefferson was a good writer but folks today aren't. Well TJ was one of the best writers of his generation. Most any luser here on slashdot can write better than the average human of 1760.

        • I think the difference is in degree. We are in the middle of a groundswell in the number of coders, both in the US and worldwide. The lure of being the next Gates or Jobs (and they probably think he was a developer) has been sinking into society for a couple decades now. Add to that all the pushes to put disinterested kids into coding courses, or even to make it a mandatory course. All this is going to decrease the skill of the average coder, as people start getting into it for the wrong reasons.

          • While I agree with most of your premise...the one crack in its foundation is that coding isn't required for non IT jobs. Many many many engineering and scientific jobs are going to need passable coding skills to be competent.

            Even within the IT world, the 'tester' is fast becoming their own flavor of a programmer. It's no longer viable to manually plod through an application as a human. You need repeatable testing 'scripts' that exercise that application. That's programming as well.

        This is rose-tinted thinking. We didn't have a clue about methodologies and processes in the 80s either, when I taught myself to code in BASIC. Version control? I'd tell you I'd heard of it but I hadn't. Early 90s I did - I copied directories to different names. rcs etc.

        There's irony in putting that in an article praising GitHub, i.e. git, written by a guy who resisted source control for so long and then claimed it was because every system was rubbish except his. He knew nothing about process either.
        • You mean you didn't have a clue about methodologies and processes in the 80s. We certainly did [wikipedia.org].
        • Directories?!!?!? My version control in the early 1980s was a set of numbered cassette tapes. Directories were for the rich people who could afford floppy drives.

      • It's always been that way. 45 years ago it was a bunch of COBOL programmers who couldn't write a linked-list to save their life. There have always been a core of a few programmers who are really good, with a huge mass who spend their lives implementing business logic, and never learn anything else. Even in the 50s when you had to stick wires into plugboards, there were a lot of people who didn't know what they were doing.

        (Implementing business logic in itself isn't necessarily bad, it pays the bills).
        • COBOL programmers actually couldn't write linked lists 45 years ago, because COBOL didn't have pointers at the time. It certainly has not always been like this by any stretch of the imagination. Back then simply being able to write software meant you were much smarter than average. Today the boy and girl scouts literally have teenagers thinking anyone can do it (for example.)

            That's definitely not true. IBM tried at one time to hire programmers based on chess ability, but that was definitely not widespread. When Knuth wrote AoCP some of his readers were shocked at the idea that they could write their own data structures and algorithms for common things, instead of using the vendor supplied packages.

            • Chess ability is no indication of ability to program, and I'm sorry to break it to you but there were no people of average intelligence allowed anywhere near a computer originally.

              • you're still the one who thinks you need pointers to implement a linked list.
                • You have to be the dumbest motherfucker on Slashdot today. Linked Lists [wikipedia.org] involve pointers. If the language doesn't have a built in facility to accommodate pointers then you have to use built in facilities to implement them, which is slow and phenomenally stupid. In short, you can do almost anything with a Turning complete language, except implement a Linked List without pointers. Now just shut the fuck up. Every time you post you make yourself look more and more stupid.
                  • A 'pointer' is whatever construct you use to point to the next record in the list.

                    From your link:

                    It is a data structure consisting of a group of nodes which together represent a sequence. Under the simplest form, each node is composed of data and a reference (in other words, a link) to the next node in the sequence.

                    Data and a reference. If your data record contains a record number of the NEXT record in the sequence. That's a linked list.

                    [[ a ][ 1 ]] [[ b ][ 4 ]] [[ c ][ ]] [[ d ][ 3 ]] [[ e ][ 5 ]]

                    Gives you A -> B -> D -> E -> C

          • You can implement linked lists in arrays. You don't NEED pointers.

            • You used pointers idiot. You didn't use built in language facilities that support them, so you used the built in facilities to create them. ALL linked lists use pointers. It is LITERALLY the definition of a linked list.
              • And thus, you can implement a linked list in COBOL, can't you?

                Reminds me of the Advanced C class I took with the following problem:

                Const char[] strIn="Find the comma, and change it to a period please";

                My methodology- grab the pointer to strIn, increment it until I found the comma, and change it to a period (I leave it as an exercise for the reader to implement).

                Everybody else used a strcpy first, because after all, it was a constant.

        More seriously, there are lots of reasons to have multiple GitHub accounts. There are quite a few people at Microsoft, for example, who have an account with MSFT in their name for open source work-related stuff and another account for private stuff. Additionally, GitHub uses a horrible ACL mechanism, rather than a simple capability mechanism, for authorising applications, which means that the easiest way of granting rights to monitor a repository to something like Travis-CI or Coverity or similar is to create a new account that has access only to that repository and create an OAuth token for that user. It's not surprising that the number would quadruple when there are lots of good reasons for people to have 2-3 accounts...
        • I always wondered about this. Unless something changed, I thought that GitHub's official policy was that one person is only allowed one (non-paid) account, possibly with some exceptions for things like well-known projects. But IME there are mostly only two kinds of developer: those who don't really use GitHub much other than anonymously pulling from the repos, and those who are really into it and often do seem to have several different accounts they use.

        • I admit I personally have two accounts.
        • It reminds me of when Windows Phone 7 came out. Instead of releasing sales numbers, Microsoft released the number of downloads of its SDK, which was around 10million IIRC. At that time, I had already personally downloaded the SDK two or three times for work.

          In the end, I think there were more SDK downloads than phones sold. Again, that is certainly true in my own case, I didn't buy a single one.

          Not to mention the IT ops side of devops usually have accounts nowadays because they often get involved in building and deploying such software even if they never write a single line of code, and with most large companies now going the devops route, you're probably looking at anything from hundreds of thousands to a few million users there alone.

    There is a typical logical disconnect in this summary. A lot of GitHub accounts are for students and people who are just hobbyists. Therefore a GitHub account doesn't equate to a professional developer. Also, multiple GitHub accounts per person is not abnormal.

    The researchers indicate that there are 20 million professional developers. In other words, not including students and hobbyists.

    Therefore the GitHub CEO is a moron, or his statement is out of context or is mis-quoted. Or the submitter/story writer is just making stuff up.

    20 million professional developers globally seems a reasonable estimate. Somewhere above 40 million people globally who code regularly is not unrealistic.

    Yes, I am a developer, but amongst the activities I use GitHub for, I host a website. Not all of the contributors (who have user accounts and have submitted pull requests), are developers.
