Round Table

- Gerri: working on the automatic binning in 2 and 3D

- Danilo: Working with Enrico to a solution to persistify TVecs, working to allow access nested branches/leaves in TDF (request of Totem)

- Enric: working on understanding how Cppyy works and the infrastructure, more specifically how Cppyy goes to the interpreter. Made the experiment of moving Cppyy into ROOT as the "engine" of PyROOT. Interacting with Totem colleagues about accessing their data with TDF.

- Olivier: a lot of work on the forum, collaborating with Sergey on the new graphics, validated the --web switch which allows to visualise on the browser.

- Yuka: worked on llvm last year with Raphael, submitted 3-4 patches to llvm, looking into cling code.

- Oksana: will work on the modularisation, need to collaborare

- Stefan: worked on ideas for ingestion of data as numpy arrays (will present to PPP), looking into fits with Tensorflow, LHCb saw huge benefit due to automatic differentiation

- Kim: answering forum investing quite some time in this effort.

- Philippe: busy with a sprint last week, need to work on the vector with allocator issue.
