I just taught a day long Ruby / Rails class in Feb and we had Windows users mostly, with some Mac and Linux folks too, but we all deployed to Heroku.com without issues.
My advice is to use what makes you productive now. Learn many things, but learn them one at a time or you'll frustrate yourself. Switch from Windows to Linux when Windows starts slowing you down if that makes you more comfortable.
Programming should be fun. :)
- Command line will give you the most bang for your buck every single time. Learn one small thing at a time and build upon it, you will be amazed at how much more productive and quick you will become from understanding simple commands.
- Start using Vim/Emacs. Doesn't really matter which one, the gains from using a powerful editor will (in the long run) pay for them selves.
These editors combined with the command line have shown the greatest gains in my productivity.
Now that said learning the editor will be up hill for a good chunk of the time until it clicks, so it may make sense to use something like geddit in the mean time.
There is no magic bullet with any sort of Development. Using unix like systems isn't going to make your website better or you more productive if you don't actually take some time and learn it. If you come over to Ubuntu but only use the GUI you will likely loose productivity.
Besides who cares what you write your site in as long as you -write- it.
I suppose right now a much more difficult thing for me is coming to grips with more fundamental differences in the OSes. For example, if I install a program on windows it goes into /Program Files/ and I know how to interact with it. If I apt-get in ubuntu its often unclear to me where to modify it's configuration, how to launch it, etc. This is best illustrated by the 4 hours I burned getting nginx up and running.
I am certain that this is just me not being used to the conventions but.. Well I don't know what my point is, honestly I think I am just venting now. :)
edit: Question on the VIM/Emacs suggestion. I started dabbling in VIM, but as a long time VS.NET user (I can navigate through a visual studio environment like a fish through water) it just felt.. Small. I assumed I would be better off going to an IDE (I am using python, so there are plenty to choose from). Do you have any comments on this? Is an IDE a 'drug' I could benefit from learning to break off?
If you choose Emacs, I believe VS has Emacs key-binding support built in.
VIM is just an editor with advanced editor tools. If you are looking for more of a IDE emacs really follows that path. Its highly extensible and has many more IDE type features.
Again using an IDE is fine and dandy if you ship things. :)
I am finding the learning curve to be rather steep, but I have prepared myself to pull through and come out the other side a Linux guru.
The question is this: Am I doing it wrong? Given that I am already comfortable and productive in Windows.. is it idiotic of me to try to force my square peg into a round hole? Should I at least go the middle-ground and use a VM so that my 'normal computing' is in my familiar environment and I can just drop into Ubuntu for testing/deployment?
One last bit of context: I am bootstrapping a web startup in my evenings so time is rather premium. My day job is still windows centric so context-switch issues might occur.
