I have worked on a wide variety of platforms, each with it's strengths and applications for which it is most suitable.
Linux is a very fast-growing platform for software development developed by a team of professionals and volunteers coordinated over the internet via the Linux Kernel Mailing List. Its open source licensing allows a very high degree of customization to be performed when adopting it, and its wide hardware support allows it to be used as a common platform across a variety of systems.
I have extensive experience in the development of linux-hosted Applications and User Environments, and have been both a long-time desktop user of Linux/KDE and an administrator of Linux systems in many production roles.
Microsoft Windows is probably the most widely deployed Operating System on end-user desktop systems, and as such has a great deal of momentum as a platform for new applications targetted at this market. I have development experience with low-level protcol implementation and graphical applications on windows environments.
John Deere uses a compact custom OS kernel in its embedded controller applications. This custom operating system is able to deliver extremely high speed and low overhead operation for the specialized applications in which it is used. I have developed control systems on this platform for the ->8000 tracks steering-> and AutoSteer programs
