As you can see from his user name, he has an interest in software testing and refers to himself as a "Cyber Entomologist". A cyber entomologist is one who collects information and classifies computer software bugs.
He believes himself to be the originator of the motto and policy: "Garbage In, Apology Out."
If you want to see a bug he has collected, try invoking Microsoft Windows NT calculator (and all later versions of windows before Windows 7) and set the view to scientific mode and then type or paste in:
(There are 15 open and close parentheses.) Nothing good happens, or try:
For the latest calculator bugs see Microsoft Calculator Challenge.
He also has a general interest in mathematics and related fields, like the history of mathematics.
His other interests include music, photography and he really enjoys reading.
This year he will have 57 years of computing experience, mostly testing and diagnosing stuff.
He has degrees in Electrical Engineering and Commuter Science. When he was an undergraduate he took every computer course offered - - - - - both of them.
At present he is teaching CS 115, Introduction to Computers, and CS 117, Programming for Scientists and Engineers, as a Part Time Instructor at the University of Nevada, Las Vegas (UNLV).
Let's see, what else has he done?
Machines he has programmed
He has programmed a variety of machines:
Languages he has programmed
He has programmed in:
- Machine code
- Assembly language
- Forward Sort/Merge Generator (a marvelous program for generating efficient magnetic tape sorts using Fibbinocci's series).
- FORTRAN I, II, IV, V, 80, 95
- BASIC (in many forms including the original on GE Timesharing into Dartmouth with a model 33 TTY).
- A microprogramming register transfer language of his own design.
Courses he has taught
He has taught:
Techonology he has introduced
He has introduced technologies:
- Automated Hardware Diagnostics Generation
- Generalized Microcoded Controllers
- Hostile Data Stream Testing
- Bounded Floating Point

Other things he has contributed
He is also a tool maker and has developed many tools that he frequently uses to solve problems he is working on. For example, he has developed the Useful Self Replicating Program (USRP), a compiler compiler compiler that wrote itself and ported itself to other (recursive) languages. Very useful for quickly writing parsers from very large attributed grammars.
As a member of the Association for Software Testing Special Interest Group on Electronic Voting, he has contributed to the collaboration of that group on developing recommendations to the Election Assistance Commission on the 2007 Voluntary Voting Systems Guidelines by helping to establish a wiki. He learned that skill as a Wikipedian.(2007-present)
Contributions to Wikipedia
- His first contribution was Abax
- Reformatting the citations for History of the Church-Turing Thesis
- Editing of Fuzzing History
- History of RTA Special Election Controversy
- From time-to-time he adds in-line citations or creates a page when looking for something and he can't find it in Wikipedia.
- Lately (2013-current) he has been cleaning up link rot.
Have a Nice Day!
Thanks for checking me out, have a nice day,
