Ohloh Tracks Open Source Developers 115

Posted by kdawson from the over-your-shoulder dept.
eldavojohn writes "The startup company Ohloh has a database listing 70,000 developers working on 11,000 open source projects. Their aim is to 'rank' open source developers, which raises some interesting questions about exactly how useful this tracking company is. Questions like, 'Is there an accurate way beyond word of mouth to measure the importance and skill of a developer?' I found it slightly alarming that, to this site, the number of commits (with input from the number of kudos) tells how good a developer you are."

    I don't know how representative it is, or if it might improve over time, but I looked myself up.

    I found mentions in 5 projects - _except_ they're all just versions of 2.6 kernel source with the same contribution for an obscure TV card cx88 variant I did. In practice, I'm sure I'm hardly alone in having contributions (mostly in small ways, but sometimes very considerably) to over 100 projects over the years. I guess I have to go through and add some of those projects.

    Naw, CBA. At least I can make sure my resume is accurate.

      I also don't think you're alone in finding that metrics fail to measure good programmers. My boss constantly asks me for lines of code count from developers. No matter how many times I express this to him, this is not a measure of success or of how good a coder you are.

      I tried to think of metrics to relay up the chain (a special thank you to the stat-scm goal in maven) but I come up with some pretty lame ones:
      • Code to comment ratio is desired at 1:1 (at least in the commercial world)
      • A class/method/function/procedure/module desired size should be defined and rated
      • # of Unit tests
      As you can see these are the ones that I found could be automatically gathered. And even these have exceptions. Anything else I think of either takes too much time to gather or is subjective. This is tough, I would like to default to peer review but oftentimes I find teammates voicing their personal hatred for an individual or taking into account personal qualities when ranking a developer. Real Life Example: Teammate A is from MIT and teammate B thinks everyone from MIT is a god. Unfortunately Teammate A hasn't done anything but criticize everyone's code without any constructive comments to make it better.

      I submitted this story hoping it would open dialog on measuring coding abilities in a semi-automated way.

          Not bad, but it depends a lot on the maturity of the project. Many young projects start out with several complete rewrites before they find a workable solution that performs well, is scalable, robust and reliable. And even on mature projects -- a lot of times and entire codebase is scrapped to accommodate new features: think Samba 3.x -> 4.x or GNOME 1.4 -> GNOME 2.0.

  • "Kudos" is not plural, just a word that happens to end in "s", like "pathos". "Kudo", as used on that site, is as meaningless as "etho" or "mytho". The more frequent references to "many kudos" or other treatments of it as discontinuous are also incorrect, although much less jarring.

      That was the first thing I thought of as well when I noticed their "kudos" system. Then I looked it up, and it turns out [reference.com] that kudos actually is the plural of kudo, and you can use them either way. I've never heard of it used in the singular form before, though.

    Wouldn't such a system assume that everyone uses only one handle - or, their real name - all the time for every project? If so, then a lot of people - who contribute under multiple handles, nicks, whatever you want to call their identities - are going to missed or severely under-rated.

    I would rather not have my real name attached to most of what I've contributed. One, because my code is so damn sloppy that it's embarrassing. Two, because I don't want the hassle of my real life - you know, offline - and my, uh, "digital lives" conflicting with each other. Three, if I was easy to find - online - I run the risk of being pestered with silly tech support questions.

    UrCreepyNeighbor, while an accurate description of my personality, is one of many identities I have. Same could be said of almost everyone. I'm sure "HotChic17CA" doesn't use that username when she's talking with her grandmother, for example.

      It does not. Two persons with same nick handle can commit to different projects and they are not counted as one person. One person can have different nick handles and link them to own ohloh id in project properties.

        That's one of the cool things about git (and maybe others). Each commit has both a "committer name" and "author name" field.

For example, one open source project with which I am familiar (and I am sure that many others are similar in this) keeps strict controls on who can commit. Those who do commit, therefore, are generally committing other people's code. How good are they at documenting such? Not.
