CDK 1.0: a milestone after 7 year of development

Last night, I released CDK 1.0 as the previous release candidate did not show up new major problems. It is far from a perfect release (see these still TODO's and Nightly, run by Rajarshi), but the core is pretty solid.

I would warmly thank everyone who has contributed to the project in one way or another (I worked more on maintainance than implementing functionality), as it has been a great pleasure to make CDK releases. OHLOH runs a rather nice developer hall of fame for the CDK. You'll see that Christoph's research group is the major contributor. User contributions, however, are equally important and played a bug role in the quite large set of JUnit tests we have now (3300+).

Another reason why this is an important milestone, is that it is the last release I am creating. I wrote on the user list:

In advance of the actual CDK 1.0 release, thanx very much to all that contributed big *and* small ! It was a great 7 years of open source chemoinformatics development!

Hey, that actually sounds like I am stepping down... Well, it *is* time for a new generation to step up indeed. I won't leave the project, but being CDK News editor, CDK release manager, CDK code developer is a bit much for doing outside office hours. I feel that I have clearly enough made my point for open source chemoinformatics, and it is time for something else... which will
very likely involve the CDK, but likely more as user only... I was hoping in the past few years, that the transition would go smoothly, and have been trying to get people interested in various emails, including this one; however, being humans, we wait for the catastrophe and only after that we're shocked and start doing something about it. So, yeah, I'm forced to make this drastic announcement: CDK 1.0 will be the last CDK release *I* will make.


So, who wants to take over? Some one will have to. I, however, will put my focus on other things. Very likely involving the CDK, as there are still many things I want to do. Some things I have on my list:
  • the Java2D based 2D renderer/editor
  • more accurate atom type perception
  • more articles for CDK News
  • the book "CDK for Dummies"
  • improved structure generator
  • validation
  • ...

  2. I know exactly how this feels. I had the same after more than five years open source development!

    I can tell you, it feels great taking an open source break. I hope there will be a new generation of developers showing the same passion and experience.

    And I just must say this for the commercial detractors
    "We just did that for creating open standards, open source, and open data. If you have problems with that in your business model and you call open source an enemy, then you are a chicken. Why are you getting distracted by a bunch of open source cowboys? If you are smart enough to run a business then you know that one thing is for sure, change! Open standards should help in adapting to changes and if you are not taking the leadership, another person will do that. If that are open source cowboys, then it is not their fault that you have not done that before."

  3. First off, congrats on the CDK 1.0 release!

    I certainly know how you feel, and you should definitely take a break if you need one. Having run marathons, a release like this really is a "marathon."

    Never say "never." When will the next release happen? Will you want to do it then? One friend told me he doesn't run another marathon until he's forgotten how much work the last one took.

    Open source communities take time to grow and it's a lot of work. CDK has done a great job with that. So maybe it's good to relax, but try to keep the community going and wait until the next release begins to take shape. Maybe someone will appear in the future?

    Good luck and congratulations!

  4. Geoff is right!
    Congratulations for the 1.0 release!!!

    I just could not believe you mean really "my last release"? That is like never writing a line of code again ;-)
