COMP 446 HISTORY SEC - 8/22/12 COMP 446 / ELEC Week 119

History ELEC 446 started Jan 03 using iPAQs, b 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 SEC - 8/22/12 COMP 446 / ELEC Week 120

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 SEC - 8/22/12 COMP 446 / ELEC Week 121

2010 Smartphones everywhere iTunes App Store grows Close to 250K apps Close to 50K publishers Approx 375 apps submitted per day Stats per iPad released. Same basic foundation as iPhone and iPod Touch Incredible growth Launches new product category – different than all previous tablet attempts SEC - 8/22/12 COMP 446 / ELEC Week 122

nd Quarter stats: Sales numbers and ranking differ by research study, but clearly show: Fast rise by Android platform and modest % rise by iPhone Decrease in market share from Symbian, RIM and Windows Mobile, Palm Android 2.x and various ‘Droid’ devices provide first real competition to the iPhone. About 200,000 Android devices being sold every day. Palm fades – but is now part of HP – but is HP fading?? Blackberry not giving up Windows Phone 7 announced based on Silverlight and XNA programming stack Strong rumors of Verizon iPhone Sprint ships first 4G phone New announcements every day SEC - 8/22/12 COMP 446 / ELEC Week 123

2011 Smartphones more the rule than the exception in many environments iTunes App Store grows Close to 460K apps (over 570K have been created) Over 100K publishers Approx 744 apps submitted per day Stats per iPad 2 released. Many competitors. None getting any traction SEC - 8/22/12 COMP 446 / ELEC Week 124

2012 iTunes App Store grows Close to 700K apps (almost 900K have been created) Over 175K publishers Stats per 4g iPad Google Android dominates sales, but iPhones still seen much more than Android Apple and Samsung by far the dominant manufacturers. Blackberry continues to spiral, Palm gone, Nokia still struggles Windows Phone gaining respect and momentum; however still a distant third player SEC - 8/22/12 COMP 446 / ELEC Week 125

2009 COMP 446 – iPhone Transition Mobile devices proliferating exponentially General consensus was that smartphones are for upper end market only But that is not the view of a technologist Strong desire to teach iPhone app class I was a Windows,.Net person Did not know Xcode or iOS iTunes University iOS class Taught by Apple people and at an elite university level Could handle the heavy lifting language portion of the class SEC - 8/22/12 COMP 446 / ELEC Week 126

Results from 2009 Class The Good News First class to leverage iTunes-U 9 Students – nice small class Creation of Rice iPhone Application Great Evaluations C-Overall:1.00 / 1.93 C-Organization:1.00 / 1.91 C-Challenge:1.00 / 1.85 C-Assignments:1.38 / 1.95 I-Organization:1.13 / 1.69 I-Presentations:1.25 / 1.89 I-Responsiveness:1.13 / 1.69 I-Atmosphere:1.13 / 1.71 I-Independence:1.13 / 1.88 I-Stimulation:1.13 / 1.71 I-Effectiveness:1.13 / 1.83 I-Responsibility:1.00 / 1.53 The Not as Good News C-Workload:4.00 / 3.01 I-Knowledge1.63 / 1.64 Class became very popular SEC - 8/22/12 COMP 446 / ELEC Week 127

Results from 2010 Class 2010 Course filled to limit of 10 on first day Limit raised to 16 on second day, filled in hours Acquired larger room Registration grew to 22 before first class. Accepted 5 walk-ins for a total of 27 More topics to cover in 2010 Some things had to be de-emphasized to make room Evaluations were good, but markedly worse than Far too many people to effectively support Some students signed up for course because of cancellation of another specialization course. SEC - 8/22/12 COMP 446 / ELEC Week 128

2011 Class 2011 Course filled to limit of 16 on first day Limit raised to 17, but only through reclassification of one student Bipolar reviews. Predominantly outstanding but … A few students did not at all like the concept of highly leveraging the Stanford videos. Important takeaway – most undergraduates have not had experience with SQL and HTML/JavaScript – things that are very important for real mobile applications. SEC - 8/22/12 COMP 446 / ELEC Week 129

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 few years 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 SEC - 8/22/12 COMP 446 / ELEC Week 130

Object-Oriented Terms Class Instance Message Method iVar Inheritance Super/Subclass Protocol Source: CS193p Lecture #1 SEC - 8/22/12 COMP 446 / ELEC Week description/template for an object - manifestation of a class - sent to objects to make them act - code invoked by a Message - object-specific storage - code-sharing mechanism - inheritance relationships - non-class-specific method definition

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 6 initial projects; most lasting one week. Homework and mandatory videos Videos must be watched before class Assignments due Friday at 6:00am (think of it as Thursday at 30:00). You will have all the resources needed to start early and get ahead. Final project Topic picked before October 10 th class SEC - 8/22/12 COMP 446 / ELEC Week 136

iPhone Development Videos Leveraging iTunes-U, Stanford University CS193P course. Significant homework will be in the form of watching external 1hr videos and their 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, and do problems up to and including assignment 6 (although assignment 6 may have a required and an optional component) Experiment when it started three years ago 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 2011 course offering - Download fall 2011 session available at SEC - 8/22/12 COMP 446 / ELEC Week 137

OS X & Xcode version OS X Mountain Lion has desirable but not required features Developing iOS apps does not require much disk space or GHz Large screen not needed but helpful University Macs running Lion Xcode 4.4 (or 4.4.1) is desired, not required Definite improvement over in integration and debugging Not materially different than version on videos. iTunes videos use Xcode 4.2. Read release notes for differences. SEC - 8/22/12 COMP 446 / ELEC Week 138

Optional Sessions and Support Sunday or Monday office hours with TA. Schedule to be determined between class and Richard Latimer. Ability to questions to me at any time. Can Richard Latimer as well. Level of support will vary over semester High level of support at the beginning. Support decreasing each project as over time as knowing where to look or how to debug is a very important skill for you to learn. Richard instructed to respond conceptually – not just provide solutions. SEC - 8/22/12 COMP 446 / ELEC Week 139

Week 2 Watch CS193p lectures #1 and #2 Preferably before Saturday. Definitely before next class. Complete CS193p Assignments #1, #1 Walkthrough Try and complete before next class. Due shortly after next class. Submit assignments, review lectures at Start thinking about big project Really – start thinking about big project! Next week’s lecture – mostly review of first videos and intro to Objective-C. SEC - 8/22/12 COMP 446 / ELEC Week 149

Is COMP 446 for You? Do you agree with benefits of the COMP 446 format? Lectures, projects and most importantly leveraging the iTunes CS193P videos Are you prepare to spend at least 10 hours a week on the initial projects? Are you the sort who really enjoys getting a program to work? Do you have the time in your schedule? Some do not understand or like the format If this is you, drop this course and learn iOS from books or iTunes-U Most COMP 446 students strongly say yes If this is you, you will have a great time in COMP 446 SEC - 8/22/12 COMP 446 / ELEC Week 150
