and Jlab @ Jlab</span></h3>
<p>Thomas gave us a demo of the <a rel="nofollow"
class="external text"
href="https://jupyterlab.readthedocs.io/en/stable/#">JupyterLab</a>
(JLab) installation at Jefferson Lab (JLab). The demo is
in the recording, but technical difficulties may make it
hard to follow. Luckily, Thomas prepared <a
rel="nofollow" class="external text"
href="https://halldweb.jlab.org/DocDB/0043/004318/001/Jupyter_dask.pdf">slides</a>
that highlight the important concepts. All of the JLab
Nuclear Physics farm is available via this interface.
With great power comes great responsibility.

<h3><span class="mw-headline"
id="Review_of_recent_discussion_on_the_GlueX_Software_Help_List">Review
of recent discussion on the GlueX Software Help List</span></h3>
<p>Igal posted a question on the help list with subject <a
rel="nofollow" class="external text"
href="https://groups.google.com/forum/#!topic/gluex-software/6YIyFwx4TAw">Something
went wrong with mcsmear - status code: 139</a>.
Interestingly, Thomas reported that starting some time
ago, MCwrapperBot has had crashes in mcsmear with the
same exit code. Sean Dobbs has agreed to look into it.
</p>
<h3><span class="mw-headline" id="Collaboration_Meeting">Collaboration
Meeting</span></h3>
<p>Sean and Mark have discussed talks at the Offline
session of the collaboration meeting. The current plan
is for Mark to give an overview including news from the
HDGeant4 meetings and slides from Thomas on MCwrapper,
Sean will summarize analysis and calibration, and Alex
will report on launches (if he agrees to do so). Other
topics can be accommodated. If you have a talk you would
like to give please contact Sean or Mark.
