At OSR Open Systems Resources, Inc. we are experts in system software. Windows device drivers, Windows file systems, debugging complex Windows problems, and most things related to Windows internals. And, over the past 20 years, people tell us we’ve gotten pretty good at it. Not surprisingly, in that time we've also learned a good bit about Linux system software development as well. We provide architecture and design consulting, custom software development, training, and tool kits to enable the success of our worldwide client base. In support of the development community we represents, OSR delivers free, technical content in its electronic journal, The NT Insider (TM).
