Plan 9 from Bell Labs is a distributed operating system, primarily used as a research vehicle. It was developed as the research successor to Unix by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. Plan 9 is most notable for representing all system interfaces, including those required for networking and the user-interface, through the file system rather than specialized interfaces. Plan 9 aims to provide users with a workstation-independent working environment through the use of the 9P protocols. Plan 9 continues to be used and…

Advantages and Disadvantages of Die-casting
target=”_blank”>Die-casting is the process of forcing molten metal under high pressure into mold cavities. Most die-castings are made from nonferrous metals, specifically zinc, copper, and aluminum based alloys, but ferrous metal die-castings are possible. The die casting method is especially suited for applications where a large quantity of small to medium sized parts are needed with good detail, a fine surface quality and dimensional consistency. This level of versatility has placed die-castings among the highest volume products made in the metalworking industry. In recent years, injection-molded plastic parts have replaced…
