Other sites or pages of mine
- Using unmodified consumer cameras for astrophotography (pages using the slides of a talk I have given to various clubs).
- I am responsible for the web site of Tynemouth Photographic Society at tynemouthps.org
- I also post some photos on Flickr from time to time.
-
grDraw - a graphical drawing application demonstrating the use of HTML5 <canvas> elements and JavaScript programming with them. It is my contention that now that JavaScript can do graphics like this, it is a useful first programming language for beginners to learn. It has several advantages over other languages:
- It only requires a browser and a text editor to get started.
- It is completely independent of platform (computer type).
- Distribution is simple: publish a web page. Even smart phones will then see your program.
- Java course based on classroom courses and presentations I have given over several years. Includes more than 30 hands-on exercises with worked answers. Goes into good OO design and unit testing with JUnit and EasyMock.
- fruitsq.com, about making circular objects (such as fruit) square.
- Nothing to do with imaging: Sudoku addicts might find my Sudoku helper page useful. A major difficulty with Sudoku is going back if you make a mistake. My page makes that easy. By using different colours you can highlight recent entries. You can also save the state at any time and go back by reloading it. I have also included a "Solve" button but that is only as a last resort. It does not necessarily solve the whole puzzle in one go.
- Something quite different: How time travel paradoxes are really avoided (in my opinion).
