I've been using ColdFusion since about ColdFusion 4.5. That's back in 2000/2001.. In the Allaire days...
I remember when New Atlanta put out the first version of BlueDragon. It coincided with my first Linux server setup.
I've been using both pretty much since then. With my small business, with my current day job..... I've always had my hands dirty in CF.
Recently, New Atlanta have released OpenBD (Open BlueDragon) which is a free/Open Source version of their BlueDragon CFML server. (GPLv3 license)
I've been lurking on their google groups list as I'm quite interested in the project. It (the project) seems to have a great steering committee .
This should be a great project, I haven't yet had time to play with it, but I'm watching all the discussions with great interest.
There are some blog posts turning up about the project, configs..etc.
Here is one that I just finished reading..... I might just try the Eclipse config....
