The idea is to have some time of the parallel allocated for "Hacking/break-out" sessions. For this we need some projects people can attempt to get the juices flowing and give them ideas. Ideally people bring their own ideas though.
abstraction levels
The higher level abstraction we can offer the "user" the more opportunity we have for optimising things. What is the right level of abstraction? Use cases from fitting tracks, doing things to a group of particles, selecting a range of events to store in a file.
storing objects
Right now it is impossible to add a new class to be stored in a DIGI/DST. This leads to all sorts of hacks. boost::any
? captnproto
? What are possible answers? This is related to backwards compatibility in #12
linking information across objects
We invented ExtraInfo
as some crazy hack that does not work very well. We need a better way to be able to add more information to a given object (be that a track, particle, hit, ...). This information will exist for some but not all objects in a collection. If you think of the information in an event as a big table, then this is natural, you simply add a new column.
best way to express a processing pipeline
How do you express something like "take these hits, build tracks from them, filter on X, take these other hits, build different kinds of tracks from them, filter them on Y, merge the two track collections, evaluate PID info for them, select pions with pt>5GeV" in a way that is flexible and extremely easy for humans to read, and also possible for computer to parse?

Quick note from afternoon chat :
- Graph
- std::any
- Functional.
- IO library.
- Compose objects.

What is the best way to advertise the little projects ? SLACK ? LHCb general ?
from scheduling-event-model.
Not sure about how to advertise these.
Another project:
Random access store
What technology exists out there for efficient storage that fits our needs and allows for random access. A small review of the existing chunked, column stores could be a good starting point. The advantage of being able to do random access would be not having to read through large numbers of files that are in the same stripping stream.

We discussed the possibility of having a short presentation of the projects Monday afternoon.
