A new pipe compression has been implemented in mlogger thanks to Fedor Ignatov from BINP
Novosibirsk. The way it works that the logger write into a pipe instead directly into a file. The pipe can

In the DEAP experiment, the normal MIDAS mlogger gzip compression is not fast enough for some data
taking modes, so I am doing tests of other compression programs. Here is the results.

I redid the tests from Konstantin for our MEG experiment at PSI. The event structure is different, so it
is interesting how the two different experiments compare. We have an event size of 2.4 MB and a trigger
rate of ~10 Hz, so we produce a raw data rate of 24 MB/sec. A typical run contains 2000 events, so has a

I have done a review of github and bitbucket as candidates for hosting GIT repositories for collaborative

Let me add my five cents:
We use bitbucket now since two months at PSI, and are very happy with it.

Somebody pointed out an error in the MIDAS documentation regarding maximum event size

Hi, thanks for your positive feedback. I have been using git for small private projects for a few years now
and I like it. It is similar to the old SCCS days - good version control without having to setup servers,
accounts, doodads, etc.

odbedit can now save ODB in JSON-formatted files. (JSON is a popular data encoding standard associated
with Javascript). The intent is to eventually use the ODB JSON encoder in mhttpd to simplify passing of
ODB data to custom web pages. In mhttpd I also intend to support the JSON-P variation of JSON (via the
