FeedbackForm Update Posted

Based on feedback from early testers, the re-generation of a new problem every time the form was refreshed (for example after a preview or spelling check) was confusing. People would solve the equation, submit a spelling check, then type in the answer to the old equation not having noticed it had changed. I modified problem generation to test whether a previously generated equation exists (this is easy, since it's included as the "e" hidden field in the form). If there is an existing equation and it has not expired, that equation is re-used in the new form. If the user has already filled a solution into the "x" box, it is preserved in the new form. The user is now free to solve the equation before or after requesting a preview and/or spelling check, and the solution to an equation is not lost if the feedback results in a quibble such as missing subject or body text. The updated version is available for download and in production.

FeedbackForm Posted

The FeedbackForm CGI program has finally been posted. This is still pretty rough-edged, so I'm posting it as a downloadable program with feedback from its own page and with a link from the FAQ. As things shake down, I'll add feedback links on other pages on the site.

Core memory photo added to "Computation, Memory, Nature, and Life"

I've added a close-up photo of a UNIVAC core memory plane from the Fourmilab Museum to the Computation, Memory, Nature, and Life page.

Fourmilog upgrades to Movable Type 3.121

As of 19:30 UTC on 2004-10-29, Fourmilog is running on Movable Type 3.121. If anything looks strange or doesn't behave properly, bear with us--there are a lot of things to re-test and many new options to explore.
