Linux Operating System

The Computer Science Department maintains some useful general help information for students new to using Linux, and about using Putty or SSH to connect to department Linux systems from Windows computers:

Eclipse Environment

CS150 uses the Eclipse Integrated Development Environment (IDE) for developing Java code. Eclipse is favored as a premier tool in academia and industry. A standard installation of Eclipse is available on all CS Department Linux computers for use by CS150 students. As a default, it will be assumed that students use this version on CS Department Machines. Basics of how to use the Eclipse IDE productively will be covered somewhat in lecture and more extensively in course recitations. Lab machines are currently using the Luna version of Eclipse, which is version 4.3. Eclipse documentation is found here.

Eclipse can also be downloaded for free and installed on most platforms. Eclipse is written entirely in Java, so it will operate properly on most any platforms that supports Java. This includes Linux, Solaris, Mac OS X and properly configured Windows platforms. It is assumed that many students will find it possible to install and use Eclipse on their own computers, and the instructor and GTAs will try to help informally. However, successful installation and use of tools such as Eclipse on your own machine demands some understanding of how to install and use new software on that platform, and ultimately it falls to the individual student to either succeed at such an effort or to use the resources already provided by the CS Department. The help that can be offered by the instructor and GTAs is by necessity limited.

If you decide to run Eclipse on your system, make sure you download and install the Java Development Kit (JDK) first from here. The current version of Java on department systems is 1.8 (Version 8), but 1.7 (Version 7) will also work for all coursework. After installing Java, download and install Eclipse from here. Select the version called Eclipse IDE for Java Developers. In both cases make sure you select the correct operating system.

Java Programming

Oracle provides a great many useful online resources for working with Java, including the documentation referenced below. We will explain how to use this documentation in class and recitations.

An excellent tutorial on Java is found here.

If you want more practice writing Java, there is an interactive tutorial here.

An excellent summary on System.out.printf is found here.

Peer Instruction

Peer instruction sessions are held during lectures, requiring each student to have an IClicker. The format will be described in detail at the time of each session, but it generally consists of each student answering questions individually and in a group. The premise is that groups perform better than individuals!

iClicker Registration

Register your iClicker on Canvas, in the tab on the course web page. In the iClicker ID field, enter your remote ID and select the Register button. The remote ID is the number found on the back of your iClicker remote. If you cannot read the ID on your iClicker, there is a kiosk in the bookstore where you can retrieve it.
