Netbeans 6 Dual-Licensed Under GPLv2, CDDL
Lally Singh writes "Interested in the new Netbeans 6, but didn't trust Sun's (already OSI-approved) CDDL? Sun just Dual-Licensed it under the GPL (v2) with Classpath Exception. Keep your karmic license purity and mix in all the (now compatible) GPL code you want. If you've been using Eclipse, Netbeans 6 is really worth a look. Lean, well-featured, and fast."
If it's your code you can license it however you want, for example MySQL is dual licensed under both the GPL and a Commercial license. Anyone can download the GPL version make their modifications and as long as they follow the GPL redistribute according to the GPl, or if they license the commercial version for a fee from MySQL AB they can basically release a closed source version all closed up.
If you were to dual license your code under the GPL and BSD people who wanted to redistribute modified code could follow either one they wanted, with BSD being one of the avaible choices they could close it up a lot if they so desired.
Also, if you've been using emacs, vim is worth a look. Vim is lean, well-featured, and fast.
If you are about to mod me down, keep in mind that this post was most likely sarcastic.
