I’m always looking for ways to get interactive calculations into the real world. I’ve started a blog at http://betterexplained.com, as a way to share the hard-fought insights I’ve managed to stumble upon. Here are two articles that benefit from having linked or embedded calculations:

• Mental Math Shortcuts
• Understanding Big and Little Endian Byte Order

In my ideal world, every calculation in a paper or tutorial would have a footnote so readers could play with the numbers themselves. Much of my learning has come from experimenting on my own, rather than only using the stock examples listed in the textbook.
