 16 Mar 2022, Stefan Ritt, Info, New midas sequencer version
|
A new version of the midas sequencer has been developed and now available in the
develop/seq_eval branch. Many thanks to Lewis Van Winkle and his TinyExpr library
(https://codeplea.com/tinyexpr), which has now been integrated into the sequencer

|
After several days of testing in various experiments, the new sequencer has
been merged into the develop branch. One more feature was added. The path to
the ODB can now contain variables which are substituted with their values.

I prepared some slides about the new features of the sequencer and post it here so
people can have a quick look at get some inspiration.

24 Jun 2020, Stefan Ritt, Info, New image history system available
|
I'm happy to report that the Corona Lockdown in Europe also had some positive side
effects: Finally I found time to implement an image history system in midas,
something I wanted to do since many years, but never found time for that.

31 Jul 2024, Lukas Gerritzen, Bug Report, New history plots: Zooming in on logarithmic y axis does not work as expected
|
Using the mouse to click and drag on a logarithmic y axis triggers a zooming behaviour as if the user zoomed in on a linear axis.
How to reproduce:

I fixed that and committed the change to megon02, just reload your browser. I also set ymin and ymax of the Vacuum plot to meaningful
values (not to zero!).

During my visit at TRIUMF we rewrote the history plotting functionality of midas. Instead of
static GIF images, we have now interactive JavaScript panels where we can scroll, zoom,
inspect values and much more (example is attached). We are now in a state where this is still

I like the new history system very much, but I stumbled over a couple of issues.
I used the version "Thu Aug 29 08:24:29 2019 +0200 -
midas-2019-06-b-244-gdd6585bb on branch develop":

> 1) it would be nice to have an option to format the label output (see attachment 1)
That's clearly a bug, I will fix it.

I fixed that in the current version.

Our typical use case is that a lot of people are connected to the experiment
having some history tabs open most of the time. Hence, I setup a test system and
connect to it from all kind of systems/browsers. What I see currently quite

> Also the new system is still incomplete, i.e. there is no trivial way to save a history plot into a file:
That has been implemented in meantime. Just click on the download arrow and you can save the current window in CSV or PNG format.

17 Sep 2008, Stefan Ritt, Info, New flag for auto restart

A new ODB flag has been introduced. When the logger is configured for automatic
stop and restart (/Logger/Auto restart = y), the restart delay was hard-wired
to 20 sec., which might be too long or short for some experiments. Therefore a
