© University of Colorado, 2010Course OverviewKenneth M. AndersonUniversity of Colorado, BoulderCSCI 5828 — Lecture 1 — 01/12/20091GoalsSurvey software engineering concepts, terminology and techniquesEmphasis on Agile Design MethodsWill supplement with traditional/historical material as neededTake an in-depth look at software engineering techniques for dealing withconcurrency (including model-based techniques)review PL support for concurrency2CAETE AnnouncementsIn-Class StudentsCAETE has a busy studio scheduleBe sure to exit promptly so next class can beginFood and drink are not technically allowed!They are tolerated as long as you keep the studio clean!Distance StudentsTextbooks can be ordered from the CU BookstoreCall 303-492-6411 or 800-255-9168Or order on-line at <http://cubooks.colorado.edu/>3Due DatesIn the past, due dates for CAETE students were one week behind the due dates for in-class studentsHowever, now that lectures are being made available to you in a timely fashion, both in-class and distance students will have the same due datesCAETE students need to have a “test proctor” to administer the midterm for themIf you don’t know who your test proctor is, contact CAETE to find out (Do this during the first week of classes!)45A bit about me…Associate ProfessorAt CU since July 1998Ph.D. at UC IrvineResearch InterestsSoftware EngineeringHypermedia and the WebWeb EngineeringREST-based Web ServicesA little bit more…24th semester at CU (!!)6th time teaching CSCI 5828Software Development ExperienceApproximately 16 systems, 30K — 100K LOC eachSome industry experience with IBM & UnisysExperience with academic / industry collaboration6Class ParticipationI welcome contributions to the class by studentsboth in lecture and off-lineFeel free to interrupt me during lecture to ask questions!“Stupid questions” — No such thing!Engage in discussion otherwise we get the “silent tomb” effect — Boring for you and me!If I’m speaking too fast, stop me and ask me to slow down7Office HoursBy appointmentSend me e-mail at <[email protected]>Will most likely meet with students in ECCS 127or in the faculty lounge on the 7th floor of the ECOT89Class Website<http://www.cs.colorado.edu/~kena/classes/5828/s10/>Has a What’s New page with an RSS feed that you can use to stay current with all course announcements!10TextbooksHead First Software DevelopmentDan Pilone & Russ MilesFirst Published: Jan 2008Published by O’ReillyLots of great examples; decidedly non-academic feel but covers all the essentialsWill supplement with other material throughout semester11TextbooksThe Art of ConcurrencyClay BreshearsFirst Published: May 2009Published by O’ReillyMain source of material for understanding how to design concurrent software systemsWill supplement with material on concurrency in C, C++, Ruby, Java, Python, Go, Scala, Clojure, ...TextbooksConcurrency by Magee and Kramer (aka “The Two Jeffs”)Every developer needs to understand concurrencyThis optional book does an excellent job covering this topic with a software engineering perspectiveI will be drawing from this textbook to introduce model-based techniques.12Structure of SemesterThe course will switch between the first two topicsproviding an introduction to software engineering one dayand looking at issues of concurrency the nextMay also look at additional topics later in the semester13Course EvaluationYour grade will be determined by your work onHomeworks (20%)Midterm (Tuesday, March 2nd; 20%)SE Presentation (20%)Class Project (Due at last class session; student teams; 40%)NO FINAL!14Honor CodeI encourage collaboration in this class via the homeworks, the SE presentation (2 person teams) and the class project (4 person teams)You’re on your own for the midterm!The Student Honor Code applies to classes in all CU schools and colleges. You can learn about the honor code at:<http://www.colorado.edu/academics/honorcode/>.15Late PolicyAssignments submitted late incur a 20% penaltyAssignments can be handed in up to two weeks after the initial due date (except for the final assignment of the class project)after that you are out of luck…16What is Software Engineering?The computer science discipline concerned with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting17What is Software Engineering?SoftwareComputer programs and their related artifactse.g. requirements documents, design documents, test cases, UI guidelines, usability tests, …EngineeringThe application of scientific principles in the context of practical constraintsConsider: Chemist versus Chemical Engineer18What is Software Engineering?What is Engineering?Engineering is a sequence of well-defined, precisely-stated, sound steps, which follow a method or apply a technique based on some combination oftheoretical results derived from a formal modelempirical adjustments for unmodeled phenomenonrules of thumb based on experienceThis definition is independent of purposei.e. engineering can be applied to many disciplines19What is Software Engineering?Software engineering is that form of engineering that applies…a systematic, disciplined, quantifiable approach,the principles of computer science, design, engineering, management, mathematics, psychology, sociology, and other disciplines…to creating, developing, operating, and maintaining cost-effective, reliably correct, high-quality solutions to software problems.
