Don Retzlaff, Principal Lecturer in the Computer Science Department, has retired after teaching Computer Science for thirty-five years.
Don joined the Computer Science Department as a Lecturer after receiving his Master’s Degree in Computer Science from North Texas State University (now UNT) back in 1978. Since that time, Don has taught a large variety of the undergraduate courses in the department. He is best known for developing several key courses in the department, including CSCE 4410 and 4420, the Software Development sequence where students write large-scale applications. He has also produced other courses, including the Computer Programming for Non-Majors (1020), Assembly Language Programming (2010), and most recently the Internet Programming Course (3420). His interest has always been in teaching programming languages, and throughout his tenure he has taught programming languages including COBOL, Fortran, Pascal, C, C++, Java, and the most recent and his favorite, PHP. In recent years he authored the textbooks used in the 1020, 1030 and 3420 courses.
Don is also known in the department for developing many software-related tools to help with teaching courses, as well as other applications to assist the department itself. These include the WebCompiler environment and the ABET Course Assessment Management System. Don has been the department’s webmaster since the department first had a web presence, also being one of the first departments in the university that had a website.
With his retirement, Don plans to continue developing code and writing
books, something he’s been interested in for many years. Don will
still be the department’s webmaster, as well as produce the various
student and alumni newsletters and maintain the department’s software
tools. He is in the process of publishing on the web all of his
course-related material that he has put together during his
thirty-five years in the department. He also plans to travel
extensively with his wife Elisa between doctor visits.
Dr. Gary Goodman retires from CSE
Dr. Gary Goodman began at the University of North Texas in 2007 as an Adjunct Professor and retired in 2013. He taught a variety of subjects, from beginning programming and data structures to graduate courses in automata theory, advanced algorithms, and software development. Dr. Goodman had previously taught as a TA at Stanford University and Carnegie-Mellon University; he was also an Assistant Professor at the University of Nebraska.
He has always enjoyed teaching and wanted to return to the classroom
after retiring from the corporate world. He retired from Motorola and
was delighted to find a position at UNT. Dr. Goodman said "While I
hope that I have had an impact on the students, the students have
helped me to become a better instructor and to understand what it
means to be a student in today’s world. I wish to thank the
faculty, staff, and students for making my wishes come true."

academic to corporate and startup careers.
CSE hosts NACLO 2014
The North American Computational Linguistics Olympiad (NACLO) was hosted on January 30, 2014 by the Human Language Technologies lab (HiLT) in the Department of Computer Science and Engineering. Forty-two high school students from the DFW area participated in this competition.
NACLO is an educational competition in Computational Linguistics, the science of designing computer algorithms to solve linguistic problems. It challenges students to develop strategies for tackling problems in fascinating real languages and formal symbolic systems.
Dr. Rodney Nielsen, Associate Professor, and Genene Murphy,
CSE Staff, supervised this event, along with HiLT graduate students
Jim Glenn, Natalie Parde, and Wes Solomon. For more

Applications for Bug Wars REU due February 21
The Bug Wars Research Experience for Undergraduates Site is now accepting applications for 8 positions to start in Summer 2014. More information is available HERE.
Bug Wars is an REU site project that exposes students to research on software testing and AI planning through both competition and collaboration. The intellectual merit of this project includes creating new knowledge about user-session-based testing, model-based testing with AI planning, and the combination of these two techniques as applied to web applications. A novel feature of this REU is that it encourages both competition and collaboration. The students initially split into two teams that strive to find the most faults in web application systems under test. One team collects, reduces, and prioritizes user-session-based test suites. A second team uses machine learning to build models of the software and AI planning to generate test suites. Students compete to show the merits of their approach on the same systems by considering the sizes and fault detection effectiveness (FDE) of their test suites. The students then critically discuss their work and propose combining the different approaches to further improve effectiveness.
No prior research experience is necessary. We hope that this paid
summer internship encourages participants to pursue graduate studies.
One outcome of the success of this program is the number of Bug Wars
students that decide to pursue graduate studies after the program.

Hefei University of Technology Scholars collaborate with Vision Researchers
For five weeks in November and December, four students and two faculty members from Hefei (China) University of Technology (HFUT) gained experience and shared their research with Dr. Buckles and the members of his lab. During the interval, the students participated in research by attending weekly meetings, participating in discussions, giving presentations, and creating a visualization of data obtained from a local public transit system. Their advisors, Dr. Yu and Prof. Wu, were present during the latter part of the visit to assess the students’ progress and to share information on projects underway at HFUT.
The students learned basic GIS skills and several new aspects of image
processing. The lab gained a tool for visualizing ingress/egress data
obtainable from bus-mounted cameras. The travel costs were borne by a
new national program in China to support opportunities for
multi-cultural interactions for Chinese students. At the conclusion of
the visit, both parties believed the outcomes were beneficial to each
and would be repeated when additional opportunities occur.
