Everytime I go out in the field and look at the tools that scientists are using, they are field and look at the tools that scientists are using, they are using Unidata's tools. It is our view that how you get to the CI using Unidata's tools. It is our view that how you get to the CI will be through Unidata's tools. This is why you see us speak will be through Unidata's tools. This is why you see us speak more about infrastructure than about application. We are not more about infrastructure than about application. We are not developing applications that in conflict with the existing developing applications that in conflict with the existing practices of scientists. We are there to accelerate their practices of scientists. We are there to accelerate their practices, to expand their practices. The best way to do that is practices, to expand their practices. The best way to do that is to deploy into the existing operational context and Unidata to deploy into the existing operational context and Unidata represents one of the strongest institutions in the country in represents one of the strongest institutions in the country in terms of supplying applications to the end users."terms of supplying applications to the end users."
