...object-oriented programming is a way of modularizing common concerns. AspectJ is an implementation of aspect-oriented programming for Java A join point is a well-defined point in the program flow. A pointcut picks out certain join points and values at those points. A piece of advice is code that is executed when a join point is reached. These are the dynamic parts of AspectJ. AspectJ's aspect are the unit of modularity for crosscutting concerns. They behave somewhat like Java classes, but may also include pointcuts, advice and inter-type declarations. AspectJ provides for many kinds of join points, but this chapter discusses only one of them: method call join points. A method call join point encompasses the actions of an object receiving a method call. It includes all the actions that comprise a method call, starting after all arguments are evaluated up to and including return (either normally or by throwing an exception). when a particular method body executes execution(void Point.setX(int)) when a method is called call(void Point.setX(int)) when an exception handler executes handler(ArrayOutOfBoundsException) when the object currently executing (i.e. this) is of type SomeType this(SomeType) when the target object is of type SomeType target(SomeType) when the executing code belongs to class MyClass within(MyClass) when the join point is in the control flow of a call to a Test's no-argument main method cflow(call(void Test.main())) Pointcuts compose through...

...provided in the hope that it is useful, but I can’t provide any assurance that any information it contains is in any way accurate or complete. Corrections or additions are welcome. Distribution Terms: This document is released into the public domain. Query Evaluation External Sorting • A DBMS frequently needs to sort data (e.g. for a merge-join, ORDER BY, GROUP BY, etc.) that exceeds the amount of main memory available. In order to do this, an external sort algorithm is used. • 2-Way External Merge Sort: – In the first pass, each page of the input relation is read into memory, sorted, and written out to disk. This creates N runs of 1 page each. – In each successive pass, each run is read into memory and merged with another run, then written out to disk. Since the number of runs is halved with every pass, this requires log2 N passes. Since an additional initial pass is required and each pass requires 2N I/Os, the total cost is: 2N( log2 N + 1) – Thus, we can see that the number of passes we need to make is critical to the overall performance of the sort (since in each pass, we read and write the entire file). Furthermore, the number of runs that we start with also determines the number of passes that are required. – This algorithm only requires 3 buffers: 2 input buffers (for the merging passes) and 1 output buffer. • Generalized Merge Sort: 1 – We usually have (far) more than 3 buffers available to use for sorting. If we have B buffers available, we...

...campus offers them. Not having a car doesn’t limit any student to what he or she can do. So, how do we get students to realize the many opportunities on campus? There is a solution! Students just need to pause and take a look around at the things many students overlook: fliers and websites. If students read the fliers and websites, they would see that clubs, WITR (RIT’s on-campus radio station), student government, and many more organizations are looking for help or for you to join and have fun. Reading a flier can be quick and painless. All the information you need is when, where, what and why. That is exactly what many students do when they put out fliers, especially clubs. Clubs wouldn’t survive without any active members. You practically do not have to do anything to join a club. All you have to do is show up to a meeting and give someone on the E-Board your email so that you will get the weekly emails. Joining a club can give you more opportunities to do other activities. For example, lets say you join Asian Culture Society (ACS). Meetings would be every Friday at 1:00 PM to 2: 00 PM. Usually after the meetings everyone would go out to eat, whether it be on campus or off campus. So if you don’t have a car, someone would give you a ride. It would give you a chance or two to eat off campus, instead of eating at Gracie’s or The Commons. Getting more involved with the club, rather than just being an active member, can also keep you really busy. The E-board is the behind the scenes...

...In The Red Badge of Courage by Stephen Crane, the main character Henry Fleming joins the army as a teenager without a true understanding of what war is like. Through his time in the army, Henry learns a lot about himself, and that joining the military is not something you do for yourself. Henry has the three character traits of being dedicated, prideful and cowardly, which changes into courageousness. The first character trait Henry has is dedication. When the first battle starts, the fear of death and injury get the best of Henry, so he runs from battle. Knowing what he did was wrong, Henry comes back to his regiment. Being in the army is hard, with little food, constant marching and fighting, and the fear of death, this is enough to...

...General FAQ Q. What is a wireless LAN controller (WLC)? A. Wireless networks have become a necessity today. Many corporate environments require deployment of wireless networks on a large scale. Cisco has come up with the concept of the Cisco Unified Wireless Network (CUWN) solution, which helps make it easier to manage such large scale deployments. WLC is a device that assumes a central role in the CUWN. Traditional roles of access points, such as association or authentication of wireless clients, are done by the WLC. Access points, called Lightweight Access Points (LAPs) in the unified environment, register themselves with a WLC and tunnel all the management and data packets to the WLCs, which then switch the packets between wireless clients and the wired portion of the network. All the configurations are done on the WLC. LAPs download the entire configuration from WLCs and act as a wireless interface to the clients. For more information on how a LAP registers with a WLC, refer to the document Lightweight AP (LAP) Registration to a Wireless LAN Controller. Q. What is CAPWAP? A. In controller software release 5.2 or later, Cisco lightweight access points use the IETF standard Control and Provisioning of Wireless Access Points protocol (CAPWAP) in order to communicate between the controller and other lightweight access points on the network. Controller software releases prior to 5.2 use the Lightweight Access Point Protocol (LWAPP) for these communications. CAPWAP, which is...

...Students should be given the choice as to whether or not they participate in organized school sports. Children are individuals with different interests and opinions. Those differences should be supported and encouraged by the schools they attend. There are many reasons children should be given a choice and not forced to participate in school athletics. Not all children are athletic, some would benefit equally from joining academic clubs, and requiring children to participate runs the risk of rebellion. While some students would welcome the chance to participate in organized school sports, others would prefer to sit on the sidelines. Let’s face it, not all people are athletic. Some are more gifted in that arena than others. Sports are...

...1970’s: Smalltalk is an object-oriented, dynamically typed, reflective programming language. Smalltalk was created as the language to underpin the "new world" of computing exemplified by "human–computer symbiosis."[1] It was designed and created in part for educational use, more so for constructionist learning, at the Learning Research Group (LRG) of Xerox PARC by Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Scott Wallace, and others during the 1970s. The language was first generally released as Smalltalk-80. Smalltalk-like languages are in continuing active development, and have gathered loyal communities of users around them. ANSI Smalltalk was ratified in 1998 and represents the standard version of Smalltalk. Compiler Description Language, or CDL, is a programming language based on affix grammars. It was designed for the development of compilers. It is very limited in its capabilities and control flow; and intentionally so. The benefits of these limitations are twofold. On the one hand they make possible the sophisticated data and control flow analysis used by the CDL2 optimizers resulting in extremely efficient code. The other benefit is that they foster a highly verbose naming convention. This in turn leads to programs that are to a great extent self-documenting. The original version, designed by Cornelis H. A. Koster at the University of Nijmegen emerged in 1971. Pascal is a historically influential imperative and procedural programming language, designed in...

...have a 2013 edition The Best American Essays, please open to Richard Schmitt’s Sometimes a Romantic Notion on page 27. In this narrative, Schmitt wants to lead those who think there is a way to face reality and get rid all of the nonsense illusions to realize that we are living in a world surrounded by dreams and hopes. We will never know what it is until we try it ourselves. Mr. Schmitt conveys such idea by walking the readers through the story of a narrator who runs away from home, joins a circus, and becomes a professor. What makes this essay so interesting and fascinating to read is Schmitt’s ability to control the character, to create doubt and to twist the narrator around that make the readers want to discover more about this...

...Profit maximisation is when firms maximise their profits through sales and increasing the price of products. Profit maximisation occurs when total sale revenue is furthest above total cost which is when MR= MC. Firms are usually controlled by the managers, in order for managers to keep its position its must gain enough or maximise the firms’ profits, so it can satisfy the shareholders. However managers may want to take a different approach rather than maximising the firms’ profits. Managers may want to maximise managerial objectives such as maximising its sales rather than profits. However although they are taking a different approach, they still must gain enough profits to satisfy the firms’ shareholders in order to avoid losing their jobs. Managers may want to pursue the objective of making a more ethical and greener environment. In a firm, there are many shareholders who have different views on what the company should be doing, these shareholders form coalitions. The manager may try to resolve conflicts between different interest groups in different organisations. However, attempting to satisfy the aspiration of as many groups within the organisation as possible would mean compromise and the possible of setting minimum rather than maximum targets. Therefore manager may try the method of satisficing. Satisficing means achieving objectives that are acceptable to all the competing member groups of the coalition. This concept is only used when firms are in an imperfectly competitive...

...Project: Project Part 1: Executive Summary First World Savings and Loan is a financial institution that processes credit card transactions and loan applications online. We are currently considering implementing an open source infrastructure. This could potentially save us over $4,000,000 per year in licensing fees for the software we are currently using. However, due to our business needs; we must still comply with the Sarbanes-Oxley Act (SOX), Payment Card Industry - Data Security Standard (PCI-DSS), and the Gramm-Leach-Bliley Act (GLBA). We must comply with SOX, because we are a publicly-traded financial institution; PCI-DSS, because we process online credit card transactions; and GLBA, because we are a financial institution. All of the regulations of these three compliancy laws must be met, while still maintaining the Confidentiality, Integrity, and Availability (CIA) triad. All security requirements for SOX, PCI-DSS, and GLBA can be achieved using Linux and open source infrastructure. Some examples of open source software that we might use are: Web Server - Apache Web Filtering - DansGuardian Network Firewall - Turtle Firewall VPN - Endian Firewall Community IDS/IPS - Suricata Database - MySQL File Server - Samba SMTP Server - hMailServer I would recommend that we use a "Defense in Depth" strategy, having multiple layers of access protection.
