© Peter Andreae COMP112 1:3 Introducing the Course. COMP112 is a brand new course. Designed as a first university course in Computer Science for students who have already done some programming, and already know much of COMP 102 Driven by the new NCEA standards in Programming & CS Exciting because it is a course full of students who understand something of what this subject is about. COMP 102 COMP 112 COMP 103 No programming experience Programming experience eg level 3 NCEA DT programming standards

© Peter Andreae COMP112 1:4 Introducing People. Pondy: taught 1 st year programming here since 1985 COMP112 is most exciting development in that time! David: has taught 1 st year programming in Waikato, also has lots of industry experience. Students: Group 1: Done NCEA level 3 DT standards in programming and maybe Computer Science. Group 2: Learned programming by themselves (not in a classroom) Group 3: Learned programming in another course (eg COMP102, INFO 102, other institution, school course….. Course is for all of you, but targeted at group 1.

© Peter Andreae COMP112 1:5 What did language(s) did you learn? What programming languages have you used? (find out from the people around you). COMP 102 will teach you: The Java programming language (used in later courses) More about programming More about other aspects of computer science as well. GraphicsArtificial Intelligence NetworkingSoftware Engineering Relational Databases…

© Peter Andreae COMP112 1:6 What does COMP112 assume? COMP 112 assumes programming experience up to this level: variables, loops, conditionals (ifs) input and output writing functions/procedures/methods with parameters lists or arrays little bit of event driven input, object oriented design Doesn’t care what language you used (as long as it is not drag-and-drop). What if you haven’t done enough to cope? Tell us!!! we may be going too fast. We will slow down if we are not properly calibrated. We will talk to you in labs to find out what you have done. We will let you switch back to COMP102 during the first 4-5 weeks.

© Peter Andreae COMP112 1:7 Does it matter if you aren’t …. NO!! We don’t assume you have been programming since you were small We don’t assume you spend all you life programming and configuring computers. We don’t assume you have to be male. Top student in both 1 st year courses last year was female! Top students consistently include lots of female students Four of my PhD and Masters thesis students in the past few years have been female. The fraction of women in COMP112 is a bit higher than COMP102 has had for a long time!

© Peter Andreae COMP112 1:8 Computing is everywhere Name areas of modern life where computers or computing are / are not involved in some way: ⇒ Computing underlies almost all aspects of modern life ⇒ Computer Scientists/engineers are critical for society.

© Peter Andreae COMP112 1:9 Comput er Science Computer Science is the science of Computing The study of the computing processes that happen inside computers when they are working. How do we design, build, analyse systems that deal with information: text numbers graphics and video sound sensor and control signals …. Programming is central, but not the whole field! ing Science

© Peter Andreae COMP112 1:10 Computer Science Questions How do you…. design a computer system to manage an organisation’s information? design an intelligent assistant for your phone that can talk with you? enable social interaction over electronic networks send data securely and reliably over unreliable public networks? manage large teams of programmers building insanely complicated programs (not the way Novopay did!) design algorithms that will create new visual effects for movies design a database so that it is impossible to enter inconsistent data? design programming languages to make programming easier? ensure that the computer program controlling a nuclear reactor or a spacecraft never makes a mistake? design a self-driving car that drives safely on city roads? make a safe encryption scheme for electronic commerce? determine whether some computation is tractable or even possible? design a computer system that learns to move its hand like a child.

© Peter Andreae COMP112 1:11 Role of COMP 112? A first course in Computer Science Software Engineering Network Engineering A required course for Electronic and Computer Engineering Operations Research An important course for Information Systems Media Design A useful course for Everyone IS EC SE CS NW MD OR

© Peter Andreae COMP112 1:12 What will you do in COMP 112? Design and write lots of little programs for a wide variety of tasks. 1 st five weeks: fairly small programs, getting up to speed in Java Rest of course:larger programs for Graphics:bunch of photoshop-like tools for images Networks: build an IRC client (chat program for real IRC services) Databases:Program to interface to a Relational Database. Several exercises on other aspects of Computer Science.

© Peter Andreae COMP112 1:13 Planning ahead If you are doing BE or BSc (COMP), or any 2 nd year comp sci then you should plan on taking COMP103 in Tri 2. If you are doing BSc (COMP) You should plan on doing MATH161 in Tri 2. required for entry to two 2 nd year courses (COMP261, SWEN224) and for many 3 rd year courses. Consider taking ENGR 110 in Tri 2 required for entry to one of the 2 nd year courses (SWEN223) You don’t need to change enrolment until mid-year You can’t do COMP102 at the same time as COMP112

© Peter Andreae COMP112 1:14 Planning ahead If you want to do Computer Graphics BSc in Comp Sci with focus in Computer Graphics Masters/Hons programme in Computer Graphics You will need to take COMP 112 and 103 MATH151 (or ENGR121) and MATH 161 DSDN 101 and DSDN 142

© Peter Andreae COMP112 1:25 Plagiarism (Cheating) You must not present anybody else’s work as if it were your own work: Basic principle of academic honesty. applies to work by other students, friends, relatives, the web, books… If you received substantial help, then you must state who helped and how much. If you declare any work from someone else, then it isn’t plagiarism!!! In COMP112: We encourage you to talk to each other and help each other understand and solve problems BUT The code you submit should be yours. If you got some of the code from the web or someone else, you must put a comment in your code saying that. If you use code from the text book, or lectures, or tutors then you do not need to declare it; If you use any other code that wasn’t yours, then declare it!

© Peter Andreae COMP112 1:26 Cheating in the assignments. Assignments are primarily for learning, not assessing Cheating in the assignments is not worth it! You won't learn, so you will probably fail. If caught, you'll lose marks --- or worse. Assignments have a fairly small contribution to your grade.

© Peter Andreae COMP112 1:27 Lab Facilities All scheduled labs are in CO219/238 Can also use other ECS labs Can also use home computers. Lab Hours: 24/7 Need ID card to access in evenings and weekends The labs are for getting work done Don’t prevent other people from working If you want to play around, go somewhere else Read the lab rules!

© Peter Andreae COMP112 1:29 What to do NOW! Sign up for the labs Note: You need to be registered for the course (a) to sign up for a lab (b) to be able to use the ECS school computers Read the course outline. Read Assignment 1 before your lab session You can start on the assignment before the lab session if you wish. Read the course outline. Yes, again!

© Peter Andreae COMP112 1:30 welcome, new course, intro to me and David brief descn of goals of course, leading to COMP103 and CS/SWEN/etc find out who they are : 1 st year, did ncea L3 DT:programming [explain this is the driver, I was involved] 1 st year, learned programming some other way returning, done COMP102, INFO102, or other programming course other. find out what programming languages they have used. Assumptions of what they know. note the wide range of backgrounds -> some repetition for some people. we don't know how much they know – course will need to adapt – tell us what's going on switching with COMP102 if find don't have background. Overview of course – what it will cover, and what projects – give examples of Learning – what do you do, what do we expect, differences from NCEA Admin – how the course works.
