- commodore business machines — (company) (CBM) Makers of the PET, Commodore 64, Commodore 16, Commodore 128, and Amiga personal computers. Their logo is a chicken head. The Commodore name is controlled by Commodore Licensing BV, now a subsidiary of Asiarim. Commodore USA signed an agreement with Commodore Licensing BV. On 1994-04-29, Commodore International announced that it had been unable to renegotiate terms of outstanding loans and was closing down the business. Commodore US was expected to go into liquidation. Commodore US, France, Spain, and Belgium were liquidated for various reasons. The names Commodore and Amiga were maintained after the liquidation. After 1994, the rights to the Commodore name bounced across several European companies. On 1995-04-21, German retailer Escom AG bought Commodore International for $14m and production of the Amiga resumed. Netherlands-based Tulip Computers took over the brand. Production of the 8-bit range alledgedly never stopped during the time in liquidation because a Chinese company were producing the C64 in large numbers for the local market there. In 2004, Tulip sold the Commodore name to another Dutch firm, Yeahronimo, that eventually changed its name to Commodore International. In April 2008 three creditors took the company to court demanding a bankruptcy ruling.

- dining philosophers problem — (parallel) (DPP) A problem introduced by Dijkstra concerning resource allocation between processes. The DPP is a model and universal method for testing and comparing theories on resource allocation. Dijkstra hoped to use it to help create a layered operating system, by creating a machine which could be consider to be an entirely deterministic automaton. The problem consists of a finite set of processes which share a finite set of resources, each of which can be used by only one process at a time, thus leading to potential deadlock. The DPP visualises this as a number of philosophers sitting round a dining table with a fork between each adjacent pair. Each philosopher may arbitrarily decide to use either the fork to his left or the one to his right but each fork may only be used by one philosopher at a time. Several potential solutions have been considered. Semaphores - a simple, but unfair solution where each resources is a binary semaphore and additional semaphores are used to avoid deadlock and/or starvation. Critical Regions - each processor is protected from interference while it exclusively uses a resource. Monitors - the process waits until all required resources are available then grabs all of them for use. The best solution allows the maximum parallelism for any number of processes (philosophers), by using an array to track the process' current state (i.e. hungry, eating, thinking). This solution maintains an array of semaphores, so hungry philosophers trying to acquire resources can block if the needed forks are busy.
