But as a way to explain my motivation, I will draw a history of my involvement into open source.
I have to admit that remembering that history was not easy, thanks Google I could find quite a lot of facts I had almost forgotten about my own past;-)
Let's start with my first projects, actually never open sourced, some even never released "in the wild"!
- ObjectBase: never completed (only reached specification stage in 1993)
- EasyMage: released in 1994 (C++, MacOS, shareware actually, source code never disclosed). At that time I developed this application as a passionate. And as a dreamer, I also hoped making some money out of it (IIRC, I did not pass over 100 licenses sold;-))
- SCADA (C++ & Java 1.2, around year 1997-2000): never released. But this project helped me a lot learning Java along with CORBA.
- CORBA WhiteBoard (Java 1.4, around years 2000-2003): never released. But this project gave me more experience with Java Swing. And more impotantly, it has served as inspiration roots for my second Open Source project, HiveBoard.
Now let's go further into my progressive involvement into Open Source. First of all, all projects above were developed with a spirit of "implement everything from scratch" (the DRY principle did not really exist in these times;-) and using only little third-party -open source- libraries)
My first involvement in Open Source can be traced back to 1999, it was quite limited: I have reported bugs to the omniORB library and then contributed some answers to questions in the forum. I also evangelized omniORB to my students in 1999 (I was a part-time IT professor in Vietnam at that time).
This may not look much but actually, this is very important in Open Source: contribution doesn't have to be just committing code, but also using open source code in your own projects, reporting problems, suggesting enhancements, helping other users when you can, evangelizing the products you use and like...
At that period, I have also contributed problems reports to ORBACUS/Java (which was open source at that time).
Then, much later on (mid 2004), at this time Spring started to take off seriously, I was interested in Dependency Injection but hated Spring because of its too verbose XML configuration. Then I discovered HiveMind (it was in beta at that time) and found it much more interesting than Spring. However, it was lacking all that Spring had which is not DI-related (integration with persistence libraries in particular). I found HiveMind so good a DI framework that I wanted to evangelize it, but it always failed in comparison to Spring because of the lack of 3rd-party integration. That's why I decided, late 2004, to start HiveTranse my first OSS project. Unfortunately it seems it didn't help wider adoption of HiveMind. But at least it has served me to start my second OSS project, HiveBoard, at the end of 2004.
Both projects have really absorbed my time during several years and they have helped me improving my skills in:
- Java technical area: I started to get acquainted with Hibernate, iBatis, securityfilter... I also worked with useful products like Tomcat and Jetty.
- Software lifecycle process: I have learned to use tools to help me build (ant, el4ant), and test (JUnit, jmock, dbunit, abbot). I also got used to managing issues. I had to perform quite a bunch of efforts in terms of documentation (good for changing a "standard" developer's bad habits;-))
- Soft skills: when you commit into Open Source, you have to be careful about not growing too big an ego, and rather be humble towards the mistakes you make (and the remarks you get about these mistakes). You have to listen to what others tell you and accept criticism on your project. In other words, you have to "open up", this is one quality I believe I have grown during my Open Source years (although I am far from perfect to this regard;-))
What I have learned from DesignGridLayout is:
- how to design a good API (I believe)
- how to "market" the project (although the results don't seem compelling so far)
- how to keep my cool (or at least, try to;-)) when facing some "attacks" from other people
To sum up with the reasons I do open source:
- learn more about new technologies (very important in our profession where technology evolves at a fast pace) without any external constraint (you can choose the latest "cool stuff" to try and integrate in your work)
- learn more about tools to help the release management process (these tools I can later on push them in a professional environment in my daily job)
- give back to the community what the community has given me
- hopefully help the others by giving away something you consider useful to other people
- get some visibility (open sourcing the projects you originally used for yourself brings some extra "cost" in terms of time, so you definitely want to have these efforts "paid back": the reward here is the kind comments on your projects, the bugs reports, the suggestions for improvements...)
- get some "technical respect" in my daily job (engineers in my company respect me, not just because I'm older than them and I am their boss, but because they can see that I have a proven record of technical background and I am not just a stupid manager who understands nothing to software development)
Actually I think that's not very far from what Kirill and Alex have mentioned: such a long post to say the same as others already have! Promised, next time I blog I'll try to talk only about new stuff;-)
For those who have read until there to see who would be the next ones to be prompted for the reasons they do open source, sorry guys, you have read all my prose for nothing, I have nobody left on my list (or contrarily I have potentially too many to enumerate);-)
