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.

RunWithScissors() (2009)
The documentation is itself fairly funny, for those who don’t care to click ahead:
> This "function" has a superficial similarity to ‘unsafePerformIO’ but it is in fact a malevolent agent of chaos. It unpicks the seams of reality (and the IO monad) so that the normal rules no longer apply. It lulls you into thinking it is reasonable, but when you are not looking it stabs you in the back and aliases all of your mutable buffers. The carcass of many a seasoned Haskell programmer lie strewn at its feet.

Monthly Hask Anything (July 2022)
If you bring in efficient strings from bytestring, densely packed arrays from vector, and an in-place sort from vector-algorithms, you can bring it down to 275ms (uses 19MB of mem).

Note that this release is broken for Windows.

Beginner level tutorial - bytestring
I've opened https://github.com/haskell/bytestring/issues/455 so the situation can be improved. You're very welcome to chime in on the discussion or to contribute some of the missing documentation yourself! :)

Dragging Haskell Kicking and Screaming into the Century of the Fruitbat :: Reasonably Polymorphic
Well, ByteString in particular should not have an IsString instance in a new report. That's pretty clear by https://github.com/haskell/bytestring/issues/140 : the concensus is that there is no good solution right now, but it should not have gotten an IsString instance in the first place. If a theoretical new Haskell Report 202x includes OverloadedStrings (as it should) to handle string literals analogously to numeric literals, I'd expect it to not give ByteString (which is really just a collection of octets) an IsString instance, with all it's issues and rattail due to the encoding question being implicitized.

How can Haskell programmers tolerate Space Leaks?
Standard streaming libraries. They are being written by people that make the effort to understand performance and I have a hope that they make sure their streams run in linear space under any optimizations. It is curious and unsettling that we have standard lazy text and byte streams at the same time — and the default lazy lists, of course. I have been doing some work on byte streams and what I found out is that there is no way to check that your folds are actually space constant even if the value in question is a primitive, like say a byte — thunks may explode and then collapse over the run time of a single computation, defying any effort at inspection.

An alternative front end for Haskell?

Or patterns proposal: Prefix signalling or just infix?
Additionally, while this proposal is focused on the simple implementation and so in the current proposal or patterns do not bind any variables as per #522, if we do get settled on syntax and then later wish to expand to allow binding variables as in #43, then the syntax is again clean and discoverable.

Monthly Hask Anything (May 2023)
Yeah, a relatively natural thing would be to be able to opt-in to having the HasField instances be available in all contexts. The (not yet implemented, but accepted) "Modifiers" GHC proposal might be nice for that.

Is there any way to build a simple additive prelude?
The local modules proposal imo is excellent as-is.

Interview and AMA with Simon Peyton Jones
Why would you drop TypeFamilies? It seems fairly popular, given that it was just one vote short of getting added to GHC2021. Do you consider it a less-ideal compromise, that is subsumed by your second proposal (Core with GRTT)?

Amendmend proposal: Changed syntax for Or patterns
as syntax is contentious a topic as ever, David (the main proposal author) and I would like to invite you to give your input on https://github.com/ghc-proposals/ghc-proposals/pull/585, where we propose to change the syntax of the accepted proposal #522 introducing Or patterns. In particular, we'd like to know

MSc Dissertation: Comprehending Pure Functional Effect Systems
This looks great, congratulations on completing it! I assume you didn’t get an opportunity to evaluate the delimited continuations based eff library? It would’ve been nice to see Cont included as one of the effects covered, though perhaps not available in all the systems you looked at? Maybe some future work.

{-# WARNING #-} for Data.List.{head,tail} in future GHC 9.8
Right. Being able to disable "custom type warnings" at use sites was part of an earlier proposal (https://github.com/ghc-proposals/ghc-proposals/pull/454) but it ended up being shelved.
