// Yachts and Racing Dinghies This paper is part of a site exploring designs for a new computer platform. See here. ::: What we are proposing is not a general-purpose system In computing, there is a general-purpose-computing niche. Platforms in this niche seek to be effective as personal computer, workstation and server. They use layering extensively. Examples from linux: x-windows; sockets as a kind-of-file; advanced filesystems. Often, the layers are flawed abstractions. Complication abounds. The Dinghy concept lives in a different niche. ::: Analogy: yachts and racing dinghies Below is a review of a prestige bluewater yacht. This range is aimed at couples who want to sail long distances in their own company only. This is a large set of design needs. Discovery 58 review in Yachting World https://www.yachtingworld.com/yachts-and-gear/what-makes-a-good-bluewater-yacht-discovery-58-68835 The review praises the way this system has accomodated those needs. Yet, "It was difficult to get the yacht into a groove and too easy to wander off course if you didn't have an eye on the wind gauge, compass or, later, a star." Racing dinghies are close to the water and responsive.

Yacht: a single capsize has fair change of people getting killed. Racing dinghy: "if you didn't capsize, you weren't sailing hard enough."
