Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Event Sourcing
I was part of that debate, I remember a rather interesting point of discussion: Is the main operation "apply" or "dedup"
Apply seems to be the common notion of event sourcing: There is a function apply that takes a state an event and yields a new state. Then, starting in an init state and iteratively applying the entire event history, boom, latest state restored.
Dedup has a lot of charm though: Run and rerun your code, if that step of your code is executed for the first time (no corresponding event in the event history) execute the step and store its result as an event in the history, however, if that step of your code is executed for the second, third time (there is a corresponding event in the event history) do not execute the step and return its result from the event in the history. The Haskell Workflow Package (https://hackage.haskell.org/package/Workflow) is a good example
Temporal follows the second approach, so "proper" Event Sourcing? You be the judge :)

record - Anonymous records
basic-prelude - An enhanced core prelude, meant for building up more complete preludes on top of.
abstract-par
rio-orphans - A standard library for Haskell
hask - Category theory for Haskell with a lens flavor (you need GHC 7.8.3, not 7.8.2 to build this!)
