EE Student Workstation Lab Status Report December, 1988

The Maclab project in the Spring of 1988 demonstrated that providing a Macintosh workstation environment to some sections of EE 267 (Digital Logic Design Laboratory) was both useful and feasible on a small scale. The goals of the EE Student Workstation project this past Summer and Fall were: A. To provide all sections of EE 267 (approximately 200 students) with a Macintosh workstation environment for the simulation of digital logic circuits and for the preparation of reports. B. Tb provide a useful Macintosh workstation environment to other Electrical Engineering students. C. To transfer responsibility for operational aspects of the Macintosh Workstatiori facilities to the Engineering Computer Network (ECN). The opening of the new Materials Science and Electrical Engineering (MSEE) building in August 1988 provided space to establish the EE Student Workstation Laboratory; The facility occupies two rooms (186 and 190) within the terminal room complex of the MSEE building. The lab is equipped with 40 Macintosh Plus personal computers networked together via AppleTalk and bridged to the Engineering Computer Network (ECN). A Macintosh Il with two 40 Megabyte hard drives is used as an applications server. Application serving can also be handled by one of ECN\u27s Sun Server Machines. Using Aufs (Apple-Unix file serving) software, students can access and store Macintosh files on their regular ECN UNIX accounts. Each room is equipped with a dot matrix and a laser printer for hard copy output. An instructor\u27s machine is equipped with an LCD display and overhead projector so that large screen class demonstrations can be given. The goal of expanding use of MacIntosh student workstations to all EE267 students was successful. In addition, software purchases were made to make the facility a useful and productive environment for other EE students. Significant progress has been made in integrating this type of facility into normal ECN operations. This report describes the operation and status of the EE Student Workstation Labs as of the end of the 1988 Fall semester. Recommendations based upon the experience gained during the semester are made

Application Calling

The motivation for the development of Application Calling grew from an interest in offering a large number of users access to software on an AppleTalk network. The goal of Application Calling was to give access to applications and yet: • limit the disk space requirements • protect software vendors from unauthorized copying of software • maintain the standard Macintosh interface • allow for easy software updates Application Calling does this by using a different method of accessing software. Instead of every user having a copy of an application, every user has a copy of a small file which launches or calls up” the real application. The real applications are then hidden so that they cannot be easily copied. There are, however, two disadvantages to Application Calling: • it can be difficult to implement because the applications must initially be altered using a special application • some applications may not be able to be altered properly The following paper is divided into two major parts. The first part presents ways to use Application Calling, and the second explains the technical points of setting it up

Oral history interview with John Lindenlaub, 2008 Apr. 7

John C. Lindenlaub is a Purdue Emeritus Professor in the School of Electrical Engineering and Computer Engineering. He discusses his affiliation with LARS [Laboratory Applications for Remote Sensing] in data handling and analysis, as well as his role as program leader and his responsibility for the development of education and training materials related to remote sensing. Lindenlaub was co-author of Slide Tape Study Guides on the Fundamentals of Remote Sensing. The study guides utilized a hybrid Lecture/Self-study system as well as an audio tutorial. Lindenlaub is also an IEEE Fellow and listed in Purdues Book of Great Teachers
