Learning to program is hard: take � advantage of every help you can get. Don’t be shy. There are no stupid questions. � Criticism welcome, but always be polite to every participant and � observe the etiquette. To email the whole teaching team (professor and assistants): eprog-assi@se.inf.ethz.ch Chair of Softw are Engineering I ntro – Lecture 1 If you need a laptop… 24 � ETH has really good prices � NEPTUN program � Several brands � You choose your OS: Windows, Linux, MacOS � Limited time only: see http://www.neptun.ethz.ch Chair of Softw are Engineering I ntro – Lecture 1 8
Exercises, “Testat” regulations 25 “Testat”: Needed for admittance to fall exam. � Exercises: � � 7 weekly assignments � 3 classroom exercises � 1 project exercise To get the “Testat” you need to have done at least: � � 5 weekly assignments � 2 classroom exercises � 1 project exercise � Must show serious effort to address the questions � Must have filled out questionnaire Military services or illness � contact your assistant. � Chair of Softw are Engineering I ntro – Lecture 1 The software 26 � The exercises rely on the TRAFFIC and Flat Hunt software � Application domain: Transportation system in a city � EiffelStudio download: http://www.eiffel.com/downloads/ Chair of Softw are Engineering I ntro – Lecture 1 You’ll discover Flat Hunt 27 Chair of Softw are Engineering I ntro – Lecture 1 9
Behind the software 28 � Patrick Schoenbach � Michela Pedroni � Till Bay (EiffelMedia library) Numerous ETH students including Marcel Kessler, Sibylle Aregger, Rolf Bruderer, Ursina Caluori, Roger Küng… Chair of Softw are Engineering I ntro – Lecture 1 Warning 29 � Not everything will be perfect from our side. � The software (TRAFFIC, Flat Hunt) probably has mistakes (“bugs”), and the textbook too. BUT: � We will correct our mistakes, as quickly as we can. � If you try something, don’t blame the software first. It may be doing just what you told it to. Chair of Softw are Engineering I ntro – Lecture 1 Why this approach? 30 � Many software issues become really tough for big systems � With other approaches, in an introductory course, you’ll only see small programs � We give you a considerable amount of existing software; you can use it as model and inspiration � You learn to use software through abstract interfaces (also known as contracts ) � You go from consumer to producer: outside-in � TRAFFIC and Flat Hunt are graphical and fun! � You should at the end be able to understand all! � Then you can participate too!
