"OH WATERS, TEEM WITH MEDICINE TO KEEP MY BODY SAFE FROM HARM, SO THAT I MAY LONG SEE THE SUN." - Rig Veda
Por alguma razão, não me surpreende que isto seja no Gerês.
The construction is a concrete monolith. Only the movable elements are made in light steel structure. Both concrete and steel walls are insulated with rock wool, and covered with 15 mm slabs of waterproof alder plywood, that was stained to darker tone, in order to make the house look alike the other buildings in the surroundings. The fence, that unites with the movable walls, is the same 2.2 m high, and is covered with an identical dark plywood. The interior, to stay in contrast, is kept in white. The floors are made of concrete and whitewashed oak. The walls and ceilings are finished with concrete and whitewashed cement plates.
The Yale team compared the evolution of organisms and computer operating systems by analyzing the control networks in both a bacterium Escherichia coli and the Linux operating system. They report their findings online in the May 3 edition of the Proceedings of the National Academy of Sciences.
“It is a commonplace metaphor that the genome is the operating system of a living organism. We wanted to see if the analogy actually holds up,” said Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics; professor of molecular biophysics and biochemistry, and computer science; and senior author of the paper.
Both E coli and the Linux networks are arranged in hierarchies, but with some notable differences in how they achieve operational efficiencies. The molecular networks in the bacteria are arranged in a pyramid, with a limited number of master regulatory genes at the top that control a broad base of specialized functions, which act independently.
In contrast, the Linux operating system is organized more like an inverted pyramid, with many different top-level routines controlling few generic functions at the bottom of the network. Gerstein said that this organization arises because software engineers tend to save money and time by building upon existing routines rather than starting systems from scratch.
“But it also means the operating system is more vulnerable to breakdowns because even simple updates to a generic routine can be very disruptive,” Gerstein said. To compensate, these generic components have to be continually fine-tuned by designers.
