Lecture #12 - Asynchronous Systems

Web Resources:

Office Hours: Instructor & TAs

Content:

1. The Syllabus describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.
2. Midterm Makeup Exam - due December 13th, 2006
   This is a take home make up examination. You are required to do two things:
   
   1. Review your exam solution, and, for each question, describe what was wrong with your answer, if anything. Please do not feedback my solutions.
   2. Complete the Makeup Examination, linked above.
   If you complete these two tasks nearly flawlessly, your midterm grade will be raised to an 85, but no higher. You may ask any question you wish about the examination. The TA and I will give clear answers about how to tackle the problem in question.

3. Helpers for Project #4

   ADAM-Wrapper-Prototype, updated with Comm component
   All message handlers, e.g., virtually all parts, inherit from AWrapper, except for UIs that already inherit implementation from Form. UIs need to create a message handler that does inherit from AWrapper.

   DLL Loading - implicit and explicit (Lecture #7)
   How the Executives attach to the parts they manage.

   Message Framing Socket Receiver (Lecture #5)
   Communication component receivers need to do this.

   Base64Encoding (Lecture #5)
   Any component that wants to send, possibly binary, files needs to do this.

   .Net Process Creation (Lecture #6)
   Shows how to wrap a legacy EXE.

   concurrent file access
   Uses exceptions thrown when files can't be opened to try later.

   Safe Thread Synchronization, Jeffrey Richter

16. Lecture #12 folder contains a page of links to presentations and code discussed in this class. The Lecture folders will occasionally hold physical files of interest as well. Usually, however, all the materials of interest to the class are in the presentations and code folders. The contents of these folders will grow as you progress through the course.
