  21. History • ELEC 446 started Jan 03 using iPAQs, 802.11b and .Net (1.0) Web Services • Operating system premature, poor connectivity • Continued a couple more semesters with next version of software, but connectivity still an issue • COMP 446 cross registered version started fall 05 with emphasis on smartphones • Not well organized • Windows Mobile 3 and GPRS didn’t cut it • Reasonable Internet Connectivity by fall 06 • Beta tools still an issue • 2008 was a banner year for Smartphones • Introduction of the iPhone app store • Initial shipments of Google’s Android • Windows Mobile becoming much less relevant • Wide deployment of 3G networks COMP 446 / ELEC 446 - Week 1

  22. 2009 • iTunes App Store a HUGE success • iPhone remains the smart phone to beat • Limited to AT&T – others wanted iPhone competitor • Great support for Google Android • Second Generation phones started to come out • New competition from Palm • Blackberry and Nokia still holding on to large customer base • Windows Mobile continues to lose ground – but many have been hurt counting Microsoft out; particularly in an important area. • Ecosystem taking smart phones seriously and smart phones starting to thrive COMP 446 / ELEC 446 - Week 1

COMP 446 / ELEC 446 - Week 1

  28. 2011 Class • 2011 Course filled to limit of 16 on first day • Limit raised to 17, but only through reclassification of one student • Maintaining hard line on class size • If anyone plans to drop, please let me know so I can inform a person from the waiting list. • Will devote more time to iOS and ecosystem topics at the expense of some ancillary topics. COMP 446 / ELEC 446 - Week 1

  29. Prerequisites • Formal prerequisites for COMP/ELEC 446 dropped • There are no other courses teaching Xcode, Objective-C, ASP.Net or other web programming • Experience from last year clearly shows need for: • An interest in cool connected mobile devices is a must. • Homework will be satisfying when completed, but will likely take a long time. • Understanding of basic object oriented programming concepts (class, instance, inheritance, etc.) • Without OOP foundation, you will get lost in Objective-C tutorial and likely have trouble catching up COMP 446 / ELEC 446 - Week 1

  30. Object-Oriented Terms • Class (description/template for an object) • Instance (manifestation of a class) • Message (sent to objects to make them act) • Method (code invoked by a Message) • Instance Variable (onject-specific storage) • Inheritance (code-sharing mechanism) • Superclass/Subclass (Inheritance relationships) • Protocol (non-class-specific method declaration) • Source: CS193p Lecture #1 COMP / ELEC 694, Seminar #1

  31. Resources COMP 446 / ELEC 446 - Week 1

  32. Hardware / Software • Development Macs • IT run Campus Macs loaded with XCode software environment and emulators • Dedicated Mac Mini available for class use via LogMeIn • Devices • A few older (personal) iPhones available for student use • 2 Windows Phone 7 Device available • A few Motorola Droid (Android) devices are available • Server (likely not needed by students) • DiscountASP.Net account, www.comp446.com/ws<Application> where Application is your application name (e.g. www.comp446.com/wsAssignments) • Access to MS SQL Server 2008 located on DiscountASP.Net • Credentials to be set up and disseminated later if needed. COMP 446 / ELEC 446 - Week 1

  33. Software • Course Website: www.comp446.com • assignment submission website linked through www.comp446.com • iPhone Developer Program • iPhone Documentation available at http://developer.apple.com • Students will be enrolled in Rice’s iPhone University Developer’s Program • You should have already responded to invitations COMP 446 / ELEC 446 - Week 1

  34. Course Format • One formal classroom meeting a week • Round table, project management style • Likely optional Monday review / Q&A session with TA • Typical class flow: • Events of the week • General discussion / review of previous week’s technology or assignment • Short lecture on a technology. • Discussion of current project, future projects and / or next step in current project • Homework • Weekly projects through 10/26/11 class (due 11/03/11) • Homework and mandatory videos • Videos must be watched before class • Assignments due day after class (8 days to complete). • You will have all the resources needed to start early and get ahead. • Final project 10/19/11 – 11/30/11 COMP 446 / ELEC 446 - Week 1

  35. iPhone Development Videos • Leveraging iTunes-U, Stanford University CS193P course. • Significant homework will be in the form of watching external 1hr videos and most of the coordinated exercises. • Expect 2 full and possibly one optional video per week as well as one application through the first half of the semester • You will eventually watch all of the CS193P lectures, but only do problems up to and including assignment 6 • This was an experiment past two years which proved quite effective. It will be nearly impossible to do the assignments without watching the videos. • Logistics: • iTunes => App Store => iTunes U => Stanford => iPhone Application Programming • Subscribe and download everything from Fall 2010 course offering • http://www.stanford.edu/class/cs193p- Download fall 2010 session available at http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2010-fall COMP 446 / ELEC 446 - Week 1

  36. OS X & Xcode version • OS X Lion has desirable but not required features • Developing iOS apps does not require much disk space or GHz, but likes big screen. • Borrows from iOS • Not loaded on University Macs • Xcode 4.1 is desired, not required • Definite improvement in integration and debugging • Different than version on videos. Possible confusion. COMP 446 / ELEC 446 - Week 1

  37. Optional Sessions and Support • Sunday or Monday office hours with TA. Schedule to be determined between class and Richard Latimer. • Ability to email questions to me or to Richard. • Richard instructed to respond conceptually – not just provide solutions. Knowing where to look or how to debug is a very important skill for you to learn. COMP 446 / ELEC 446 - Week 1
