I’ve been thinking about the classic things to put online — command line programs from long ago such as Eliza and imagemagick. These things were all put online about 10 years ago. You can kind of tell from the websites that they are on.

Now that we have faster forms and ajax, I think that it’s time to do some of these apps again.

I chose to mess around with the pseudo-physics package this evening. I probably should have done work, or slept. Probably slept.

Anyway, I cleaned up the code…er, all the physics stuff is in one place. More importantly, there are controls for the equations.

The green box in the top right sends parameter info to trace. No use to you.

The dark blue circle is friction. Friction greater than 1 means things accelerate on their own accord.

The translucent purple dot is the black-hole, center of the universe.

You’ll figure the rest out.

I came across this website http://www.newstudent.umsl.edu/grad/grad.html. Look for the change color link on the left of the menu bar.

I’m glad to see that someone is using technology to enhance the user interface

I recently moved from charlesdietrich.com, and in addition to changing the domain name, I changed to WordPress, which meant that my filenames changed as well. So, for example http://www.charlesdietrich.com/news/ turned into http://www.charlesdietrich.com/blog/. Fortunately, I run Apache and there is mod_rewrite.

So what exactly goes in the .htaccess file at charlesdietrich.com? See here.
