GPL License Question
-
If I use GPL'd source code in my app, do I have to make the entire app available under the GPL, or just the code I used?

What is SaaS? What if I just used a binary and didn't download the source code? Ahhh, software as a service - well, the web app that would be using the GPL'd code would only be available on the intranet, and nobody is charged for its use. Further, only users that have the appropriate account on the server will be able to use it, and none of them would be interested in th source code (assuming they know what "source code" is).

Or look for LGPL code. There don't seem to be as many areas that are subject to interpretation like what constitutes a service. Nude photos are optional but frankly I think it's too much information.

Indeed - everything that open source hopes to acheive in terms of software quality could equally be done with "open test framework" software (i.e. anyone can submit any test and the software is tested against it with the results public) without the inherent devaluing of developers intellectual property.

My interpretation says thats ok. GPL is to prevent commercialization of an open source code base, hence being closed. IF there is no commercial factor, then u can use/modify it, as the final code will never be produced to the public.

that's just retarded. RedHat, for one example, has 11 pages of job openings. i'm sure there are plenty of traditional software companies that would kill to have the resources available to hire 250 people.

Yeah... All those companies (Microsoft, Oracle, CA, etc.) that have been around for some time making money on so-called closed source for years before there was an real open source movement are just
STRUGGLINGnow... As well as the developers that work for those companies, I am sure... Does anyone here know of any $6-figure developers that are working on completely open-source projects for a completely open-source company? I do not... You will note that many companies that make money via open-source products have either dual-licensing (which usually costs more money than the normal OSS license), or make money on support. IMHO, OSS does not pay the bills just by itself. Just something to chew on... (Notes: I use various flavors of Linux with other OSS products like MySQL, Asterisk and LAMP setups, and have briefly metMaddogwhen he was still in the NH area and I was going to the LUG in the area.)

Support contracts (or dual-licensing as with other OSS projects) at work... :) And I am sure that Microsoft can hire just as many (if not more) and considering that they are mostly "closed-source"... Peace!

See DeleteFXPFilesStallman's an idiot. I find the idea that my source code should be free to whoever wants it ludicrous and offensive. I worked hard on it, and I expect to be compensated for it. The GPL is expressly designed to prevent that, and to make it easy for less-capable programmers to steal my work and claim it for their own.

"...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001Just so everything is clear (the thread has run off a bit), yes, if you use GPL code in an application, you have to release the entire application under the GPL. This "viral" nature of it is a initial turn-off for lots of people, and why I first created the FSCL[^] some years ago back in my credit-where-credit-is-due years when I was writing articles for CG, CP and other sites. If you are using a library, or code that is normally used to build a library, it may be under the LGPL (GNU Library General Public License, although they now call it the lesser GPL to give it a negative connotation). The LGPL allows you to link the library into a non-open-source project and does not require you to place all of your code under the GPL. Note that if you make any changes to the library, you still have to release those changes to the public. Some other OSS projects have dual/multi-licensing, so that you can use the GPL version with code you plan to release under the GPL, or purchasing a "commercial" license that allows you to use it in a commercial project and not get involved with the GPL at all. Peace!

To be fair, I do not believe that the GPL was designed to do that, as many GNU proponents can be heard repeating the mantra "free as in speech, free as in speech," although it does leave a
largeopening for stuff like that to happen... I do agree with the first part of your post, however... :P Peace!-=- James
