Reducing the Parts
Part of the botheration is in how technologists assort skills. I acclimated to explain to my development agents that you are not a accurate blazon of programmer. You are not authentic by the apparatus but by what you produce.
In truth, best technologies allotment accepted elements, with the differences abundantly actuality semantic and logistic. But the amount accomplishing of one technology is, in fact, absolutely agnate with that of addition accompanying technology.
Here's an archetype to illustrate. Numerous Novell engineers were larboard abaft aloft the arising bazaar ascendancy of Windows NT. They acquainted that they didn't accept the time to apprentice Windows NT while acknowledging and developing their accepted NetWare environments.
However, technologists who accepted that the differences amid the two operating systems were not so abundant bound added Windows NT skills. In fact, they accept that whether it is NetWare, NT, Banyan Vines, or some added arrangement operating system, notable similarities fabricated the technology philosophically similar.
In their amount utilization, the arrangement operating systems mentioned are still artlessly methods for the storage, retrieval, or affiliation of abstracts and applications. In each, you had users, groups of users, protocols, and connectivity.
I am advisedly oversimplifying the abstraction to accomplish the point. The actuality is that abounding technologists who were added conceptual in their access fabricated the alteration with little or no training. They accept how to abstraction and accept new technology bound and after panic, as declared in the area that follows.
