VolcanoCam FAQs

About The VolcanoCam Web Site

Why did you switch to a different design? The previous design was working very well for me.

The current design for the VolcanoCam web site is the required look and feel for all Forest Service public web sites. We are just bringing the web site up to the required standard. While the older design was working quite well for many people, it did have some inherent problems than could not be fixed, not to mention it was not the required design.

I see you are using JavaScript on the web site now. I heard JavaScript was dangerous to use.

The real "problem" with JavaScript as seen by some web developers is that is creates what is called a user dependency. That means if JavaScript is turned off by a user the web site may not work properly or as intended by the web developer. There is nothing wrong with using JavaScript on a web site. In our case, it allows us to use some "Web 2.0" features we would not ordinarily be able to use. At the same time, if JavaScript is turned off on your web browser the remaining code will degrade gracefully and not cause problems. For example, if you are using Firefox to view this web site, and you have the Web Developer toolbar addon installed, go ahead and disable JavaScript right now. While the left navigation will not function as intended, you will still be able to navigate around the site. So the VolcanoCam site still remains accessible. Ok, you can re-enable JavaScript.

I'm having problems viewing the VolcanoCam image now that you are using a Java applet. Can you help?

We went with a Java applet to reduce strain on the web server. However, that introduced problems for some VolcanoCam viewers, especially those using WebTV and non-standard web browsers. So we also have available a non-Java web page for those folks. We plan to add a no frills, generic web page view as well for web users with smaller computer monitors.
