Reading an FADC buffer often needs large buffer size, especially while several
FADCs work together. I want to know how large a bank32 can support. |

It turns out the the standard event builder fragment matching algorithm cannot
be used in my TPC application. I have two TPC-USB interfaces, which lack any
"busy" or synchronization logic. I send the hardware trigger into both

At DANCE we have a similar issue. We are still doing "software
handshaking" between multiple frontends (15 which read data, and 16th
with direct accessto the trigger logic), and we apply a time stamp

At CERN I see a large number of hostile network scans that seem to be injecting HTTP requests into the
MIDAS RPC ports. So far, all these requests seem to be successfully rejected without crashing anything, but
they do clog up midas.log.

Doing this through the ODB seems ok to me. If the ODB cannot be accessed, you can fall back to no protection.
At PSI we fortunately do not have these network scans because PSI uses a institute-wide firewall. So you can connect from outside PSI to inside PSI only |

Hi,
I have a bank of floats with slow control values that I store to the history and
ODB. When reading the history, both in the webbrowser and with mhist, the floats

Dear experts,
I would like to have some clarification about the meaning and use of the
tags in the ODB under /History/Tags.

This part of the system has been designed by KO, so he should reply here.

That's right. Some of this stuff is historical gibberish that is no longer needed

I have been trying to fix this myself but my javascript isn't strong... The
'new' history plot render fills in missing data with the last ODB value
(even
when this value is very old...
elog:2180/1 shows this... The data logging stopped, but the history plot can

into thinking data is logging (The export button generates CSVs with

This is a known problem and I'm working on. See the discussion at:

The problem has been fixed on commit 825935dc on Oct. 2021 and runs fine since then at PSI. If TRIUMF people
agree, we can close that issue and proceed.

My first question would be why are you using several font-ends at all? That makes things more
complicated than needed. In the normal FE framework, you can define either several equipment
served by one frontend, or even one equipment linked to several devices. In the MEG experiment
