While closed source development has its niche (and a very important one), it does feel a bit weird.
I’m now working on low-level development (debuggers) at ARM, one of the things I like most but also a rare thing to find good quality open source development (with the exception of the gnu tools, of course). Of course there is a portion of your work that goes back to the community (via open standards, limited support for the open tools) but it’s not easy to find a job to write code exclusively to the gdb or gcc.
What I’m finding weirder is the fact that the documentation you need is seldom on the Internet (Google or usenet). The good side is that the guys that created the standards and tools are at your doorstep, so it’s quite easy to get hold of them in case you need something off the charts. But that’s normally true with open source as well.
The other weird thing is knowing what you can tell and what you can’t. I have no idea of what part of my current project is public so I just don’t talk about anything of it. But I think that’s just a matter of getting used to, just like I did before. Besides, albeit at EBI I could even show my (or anybody else’s) source code, I don’t think that anybody ever cared that much.
At last, licences. It’s so easy when you develop GPL or LGPL (or similar). Just write whatever you want, use whatever library you need and put a GPL3 tag on your code. That’s it. Simple as that. Now I have to think what would be the impact of that library on the license of what I write, and that’s something I didn’t want to care…
Also, if a document is GPL-ed, you have to GPL it too. If it’s version 3, everything you write (including company’s previous ideas) become GPLv3 as well. That’s a big nuisance. I do understand GPLv3 for code, even apply that to my own source code, but it does annoy a lot when applied to documents.
Although weird for some reasons, it’s not bad at all. I have many more reasons to love my new job. Excellent team, great environment and an impressive code quality, which for me, is a must.
