Talent Enrichment Courses
Talent Enrichment Courses This is a collection of unique short term courses designed to bring out the talent in all of us. To Our Future Students, The ability to better one’s self is never a bad idea. It’s how we grow. In some cases it’s a physical skill or talent. In other cases it’s simply a personal enrichment. In any case, knowledge is a gift that once given can never be taken away. Western Area Career & Technology Center believes that education is the key to success. We have developed a series of short term programs with the sole purpose of personal enrichment. There is no degree awarded at the end, no fancy certificate, just the personal satisfaction of learning something new and having a good time doing it. Please review the offerings. If one of the courses seems of interest, feel free to call or write and your questions will be answered. If a class really strikes a chord and you want to enroll, again, contact us and your name will be recorded on a list for that particular offering. There is no set start date for any of the programs. When six (6) or more participants have signed on, the class will begin. Groups are encouraged to join, as it will open the class up much quicker. Respectfully, Dr. Dennis J. McCarthy Executive Director Western Area Career & Technology Center Revised 10-3-2018 30 Minute Meals Tuesday / Thursday 5:30 – 9:30 3 weeks Minimum 6 per Class In today’s helter-skelter, faced paced world, one of the most difficult tasks to accomplish is eating right. -

You Are Not Welcome Among Us: Pirates and the State
International Journal of Communication 9(2015), 890–908 1932–8036/20150005 You Are Not Welcome Among Us: Pirates and the State JESSICA L. BEYER University of Washington, USA FENWICK MCKELVEY1 Concordia University, Canada In a historical review focused on digital piracy, we explore the relationship between hacker politics and the state. We distinguish between two core aspects of piracy—the challenge to property rights and the challenge to state power—and argue that digital piracy should be considered more broadly as a challenge to the authority of the state. We trace generations of peer-to-peer networking, showing that digital piracy is a key component in the development of a political platform that advocates for a set of ideals grounded in collaborative culture, nonhierarchical organization, and a reliance on the network. We assert that this politics expresses itself in a philosophy that was formed together with the development of the state-evading forms of communication that perpetuate unmanageable networks. Keywords: pirates, information politics, intellectual property, state networks Introduction Digital piracy is most frequently framed as a challenge to property rights or as theft. This framing is not incorrect, but it overemphasizes intellectual property regimes and, in doing so, underemphasizes the broader political challenge posed by digital pirates. In fact, digital pirates and broader “hacker culture” are part of a political challenge to the state, as well as a challenge to property rights regimes. This challenge is articulated in terms of contributory culture, in contrast to the commodification and enclosures of capitalist culture; as nonhierarchical, in contrast to the strict hierarchies of the modern state; and as faith in the potential of a seemingly uncontrollable communication technology that makes all of this possible, in contrast to a fear of the potential chaos that unsurveilled spaces can bring. -
P2P Protocols
CHAPTER 1 P2P Protocols Introduction This chapter lists the P2P protocols currently supported by Cisco SCA BB. For each protocol, the following information is provided: • Clients of this protocol that are supported, including the specific version supported. • Default TCP ports for these P2P protocols. Traffic on these ports would be classified to the specific protocol as a default, in case this traffic was not classified based on any of the protocol signatures. • Comments; these mostly relate to the differences between various Cisco SCA BB releases in the level of support for the P2P protocol for specified clients. Table 1-1 P2P Protocols Protocol Name Validated Clients TCP Ports Comments Acestream Acestream PC v2.1 — Supported PC v2.1 as of Protocol Pack #39. Supported PC v3.0 as of Protocol Pack #44.

Title: P2P Networks for Content Sharing
Title: P2P Networks for Content Sharing Authors: Choon Hoong Ding, Sarana Nutanong, and Rajkumar Buyya Grid Computing and Distributed Systems Laboratory, Department of Computer Science and Software Engineering, The University of Melbourne, Australia (chd, sarana, raj)@cs.mu.oz.au ABSTRACT Peer-to-peer (P2P) technologies have been widely used for content sharing, popularly called “file-swapping” networks. This chapter gives a broad overview of content sharing P2P technologies. It starts with the fundamental concept of P2P computing followed by the analysis of network topologies used in peer-to-peer systems. Next, three milestone peer-to-peer technologies: Napster, Gnutella, and Fasttrack are explored in details, and they are finally concluded with the comparison table in the last section. 1. INTRODUCTION Peer-to-peer (P2P) content sharing has been an astonishingly successful P2P application on the Internet. P2P has gained tremendous public attention from Napster, the system supporting music sharing on the Web. It is a new emerging, interesting research technology and a promising product base. Intel P2P working group gave the definition of P2P as "The sharing of computer resources and services by direct exchange between systems". This thus gives P2P systems two main key characteristics: • Scalability: there is no algorithmic, or technical limitation of the size of the system, e.g. the complexity of the system should be somewhat constant regardless of number of nodes in the system. • Reliability: The malfunction on any given node will not effect the whole system (or maybe even any other nodes). File sharing network like Gnutella is a good example of scalability and reliability. -
