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 an ideal 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.
So here is a JavaScript course for beginners in programming.
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. You will also find some galleries of my photos here.
Our border terriers, Buddy and Kelso, both at about 14 months old.
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.
Some of my photos are now on Flickr, here.
