to actually implement such a page. The main difference from a normal MIDAS "custom" page is the data

As of svn rev 4794, midas builds, runs and should be fully usable on MacOS 10.6.4. Previous revisions did
not compile due to assorted Linuxisms and did not run because of a sizeof() problem in ss_gettid(). Also
one of the system header files (mtio.h?) present in MacOS 10.5 vanished from 10.6.

|
One possibility is to use small GIF images for each valve, which have several frames (called 'animated GIF'). Depending on the state you can use a static
GIF or the flashing GIF. An alternate approach is to use a static background image, and display a valve with different color on top of the background in
regular intervals using JavaScript. I tried that with the attached page. Just create a custom page
/Custom/Valve = valve.html

Many midas experiments work with ROOT based analyzers today. One problem there is that the graphical output of the root analyzer can only be seen through
the X server and not through the web. At the MEG experiment, we solved this problem in an elegant way: The ROOT analyzer runs in the background, using
a "virtual" X server called Xvfb. It plots its output (several panels) normally using this X server, then saves this panels every ten seconds into GIF |
