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.

Revisiting Haskell after 10 years
Writing Haskell programs that rely on third-party packages is still an issue when it’s a not actively maintained package. They get out of date with the base library (Haskell’s standard library), and you might see yourself in a situation where you need to downgrade to an older version. This is not exclusive to Haskell, but it happens more often than I’d like to assume. However, if you only rely on known well-maintained libraries/frameworks such as Aeson, Squeleto, Yesod, and Parsec, to name a few, it’s unlikely you will face troubles at all, you just need to be more mindful of what you add as a dependency. There’s stackage.org now, a repository that works with Stack, providing a set of packages that are proven to work well together and help us to have reproducible builds in a more manageable way—not the solution for all the cases but it’s good to have it as an option.

Just write the f*****g parser.
The Parsec library for Haskell uses combinators, and there are a few good resources around the internet which explore it, if you know Haskell.

Summing polynomials in Haskell
Parse the expression using parsec library ( if you're unfamiliar with it please check out https://hackage.haskell.org/package/parsec) it's a strong library for parer combinators. Once you parse the expression u need to define and sum up the similar terms. Check this example out - https://fpunfold.com/2020/05/18/making-a-calculator-in-haskell-with-parsec.html

Konbini: a new multiplatform parser library
Konbini is a functional parser combinator library inspired by Haskell parsing libraries like Parsec. It's (hopefully) fairly easy to use, and is about as performant as the better-parse library. In fact, it's quite similar to better-parse in many aspects. The main difference is in how parsers are composed. Where better-parse prefers operators and infix functions, Konbini instead uses plain functions.

Traverse/mapM for Computation Expressions
Hi everyone, I'm learning F# and currently trying to do a Parsec-like CE, just to get comfortable with computation expressions.
- Is there good introduction to the parsec library for newbies?
-
On a daily base in this sub
good libraries for parsing: parsec, attoparsec etc.

Unity to acquire Parsec for $320m
Thank you! When I read the title I only knew about https://hackage.haskell.org/package/parsec, and for a moment I was very confused…

Splitting html tags string into list of string
The more "idiomatic" way would be to use a parser library, e.g. parsec, attoparsec, or megaparsec. But even then I think it would be a lot easier to maintain if you could preserve the angle brackets <> in the input.

Ask HN: Why are all of the best back end web frameworks dynamically typed?
I found IHP straightforward:

despite not remembering much haskell!
This assumes you can get past nix for the install.
I find IHP well-designed. I just wish the licensing scheme were more transparent.

Show HN: Algora.io – Open-source development bounties
At IHP we've been using Algora for a while now and it works really great. Here's e.g. one PR that was merged last week with a bounty attached https://github.com/digitallyinduced/ihp/issues/1621 Everything was set up in less than 15 minutes and ioannis and zafer have been super helpful with any questions we had.
In general I think this is a good direction and an interesting take on the open question around sustainable open source. Congrats on the launch and keep up the great work! :)
