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.

Genuine question: how do you all use Haskell IRL?
I use it for everything: tracking personal finance and tax data (https://hackage.haskell.org/package/hledger), small scripts to gather online information that I want to track (https://hackage.haskell.org/package/cassava), sending alerts to my mobile device, etc...there's too much to list.

Working with CSVs
I personnaly use cassava which should have everything you need (even though it can be quite obscure some times). I also know about Frames which might reduce some boiler plate at the price of a step up in complexity (disclaimer I've never use it, but it's author is a serious guy so I'm sure this package as some benefits).

[ANN] ttc-1.0.0.0 - Textual Type Classes
I have done a lot of CSV development! I usually use the cassava library, though I have my own library as well. The cassava library uses FromRecord, FromNamedRecord, ToRecord, and ToNamedRecord type classes for parsing and rendering records, and it uses FromField and ToField type classes for parsing and rendering fields. An identifier type like the UserName example above should declare instances for FromField and ToField in order to be used in CSV files. For types that have appropriate Render and Parse instances, I implement general functions named something like parseFieldWithTTC and toFieldWithTTC, which allows me to declare instances as follows:

Genuine question: how do you all use Haskell IRL?
Basically everything - it's a general purpose language after all! Creating Spotify playlists, polling my local tennis courts' website to see when spaces become available, home automation stuff like turning lights and plugs off under certain conditions. Today I wrote a 20-line-or-so program to track my friend's progress in a marathon. More substantially, over lockdown I built a tool for using phones as game controllers, and it's been my primary language at work for the past five years, across two very different jobs.

What is the correct way to compile non-haskell sourcefiles in a cabal project.
The one time I've needed this, I used Shake (this particular example is likely more complex than you need). I can fully recommend it.
