New webpages with weatherdata.

Actual and past weatherdata at my location can be viewed on the new webpages The measured data are gathered every 30 seconds (daytime) to 15 minutes (at night). The webpages are usually uploaded every day at 9:00, 12:00, 15:00, 18:00 and 21:00. But if the server is not active some updates will be skipped: just check the update time on the top of each page.

Update for CD of "Gravity Interpretation".

Due to a copying error the original scripts on the CD to the book "Gravity Interpretation" have execution problems. I created a CD update that solves the problem.

This site is written in XHTML, using CSS (you can check the W3C validator links in the footer of this page) and should show up correctly with any browser. But it is mainly tested with Mozilla's Firefox (1.5-3.0), slightly less with KDE's Konqueror (3.5) and only marginally with Microsoft's InternetExplorer (6/7).
