This document discusses different approaches to implementing access control and protection in operating systems, including:
1. Using an access matrix to represent access rights, with domains as rows and objects as columns. This separates the protection mechanism from authorization policy.
2. Capability-based systems provide data and software capabilities to control access to objects and interpret access rights.
3. Language-based protection specifies access policies within a programming language and generates calls to the underlying protection system. For example, Java uses protection domains and stack inspection.

The commoditization and fragmentation of the ia community
This session will be a open format discussion among IAs.
We, as information architects, stand at the crossroads of our profession as a whole. Down one road we see the looming fate of a fragmented industry struggling to stay alive among the politics and self importance need of the very individuals who give themselves the same title. At the end of this road is the fate of a entire profession defeating itself through the lack of clarity in its own message, a lack of value in its own offering, and through simply a lack of commitment by those within. Down the other road we see a unified community we active individuals helping others and a mutual respect for their fellow practitioners. We see a clear vision, a clear goal, and true value with a solid message. What path should we choose.

Ch10 OS
Virtual memory allows processes to have a logical address space larger than physical memory by paging portions of memory to disk as needed. When a process accesses a page not in memory, a page fault occurs which the operating system handles by finding a free frame, loading the needed page, and updating data structures. Page replacement algorithms aim to select pages least likely to be used soon when a free frame is unavailable. Thrashing can occur if working set sizes exceed available memory, continuously triggering page faults.
Ch6
CPU scheduling involves selecting which process to execute next from among processes in memory. There are several criteria for evaluating CPU scheduling algorithms, including CPU utilization, throughput, turnaround time, waiting time, and response time. Common algorithms include first-come, first-served (FCFS), shortest-job-first (SJF), priority scheduling, and round robin (RR). Multilevel queue and feedback queue scheduling involve partitioning processes into multiple queues that use different scheduling policies.
