 03 Sep 2009, Stefan Ritt, Forum, Why should we use "INLINE" here?
|
[quote="Exaos Lee"]There are many "INLINE" definitions in "include/*.h". Both GNU C and C99 permit using inline functions. I still wonder why. :-)[/quote]
The INLINE statements are a relict from times where a subroutine call was in the order of a few microseconds. This was when you probably were pretty young, |

01 Dec 2009, Stefan Ritt, Info, Redesign of status page links

The custom and alias links in the standard midas status page were shown as HTML
links so far. If there are many links with names having spaces in their names,
it's a bit hard to distinguish between them. Therefore, they are packed now into

04 Dec 2009, Stefan Ritt, Info, Redesign of status page columns

Since the column on the main midas status page with fraction of analyzed events is
barely used, I decided to drop it. Anyhow it does not make sense for all slow
control events. If this feature is required in some experiment, I propose to move it

04 Dec 2009, Stefan Ritt, Info, Custom page showing ROOT analyzer output
|
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 |

09 Feb 2010, Stefan Ritt, Forum, custom page - flashing filled area
|
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
and put all three attachments |
