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.

The Great Concurrency Smackdown: ZIO versus JDK by John A. De Goes
Recently, CE3 has had similar issues reported across multiple repositories, almost an epidemic of reports!

Parallel streaming in Haskell: Part 1 – Fast, efficient, and fun
Thanks for the explanation!
So it's pull based and not push based like most other streams lib.
Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).

https://en.wikipedia.org/wiki/Iteratee
Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

Should I Move From PHP to Node/Express?
On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

Is Scala a good choice for a data intensive web backend?
fs2 for streaming.

Is “Functional Programming in Scala” 1st edition still relevant?
Finally, the last chapter has been rewritten to be based on some of the main design ideas from FS2 (https://fs2.io), which I hope will be more approachable than the 1st edition.

FS2 stream doesn't work as I expect it to
Just to clarify, is your doubt about the meaning of the api, or do you think you have found a bug? In either case, you can also open a Github discussion https://github.com/typelevel/fs2/discussions.

How to update and access state that needs to be shared across multiple API endpoints with FP?
Another more reactive solution would to use signals, as in FPR sinal network. fs2 implements this very nicely here https://github.com/typelevel/fs2/blob/8b285a6b54c63d43ed6aa3bb91365652035c90e5/core/shared/src/main/scala/fs2/concurrent/Signal.scala

Introducing effects systems S.A. ZIO at work?
Assuming the bug mentioned here is https://github.com/typelevel/fs2/issues/2568, we came up with a partial fix in a day (https://github.com/typelevel/fs2/pull/2569) and a complete fix in 2 days: https://github.com/typelevel/fs2/pull/2572. Note the original bug was opened on a Saturday. :)

Beautifying Org Mode in Emacs (2018)
My main authoring tool is then Emacs Markdown Mode (https://jblevins.org/projects/markdown-mode/). For data entry, it comes with some bells and whistles similar to org-mode, like C-c C-l for inserting links etc.
I seldom export my notes for external usage, but if it is the case, I use lowdown (https://kristaps.bsd.lv/lowdown/) which also comes with some nice output targets (among the more unusual are Groff and Terminal). Of cource pandoc (https://pandoc.org/) does a very good job here, too.

Show HN: I made a tool to clean and convert any webpage to Markdown
This is one of those things that the ever-amazing pandoc (https://pandoc.org/) does very well, on top of supporting virtually every other document format.

LaTeX makes me so angry at word
Folks feel the same way about Markdown versus LaTeX: why use something significantly more complicated where a looser, human-readable grammar works better?
For any other situations, I use https://pandoc.org/, or, generate a Word doc scriptomatically.

Launch HN: Onedoc (YC W24) – A better way to create PDFs
Congrats on the launch, I guess, but there are so many free options that I can't think of a situation where paying $0.25 per document would be justified...? Just to name a few:
Back in the days, I used to use XSL-FO [0] and it was okay. It was not very precise but it rarely if ever broke, and was perfectly integrated with an XML/XSLT solution. Yeah, this was a long time ago.
Last month I used html-to-pdfmake [1] and it's also not very precise and more fragile, but very efficient and fast.
Yet another approach would be to pro grammatically generate .rtf files (for example) and use Pandoc [2] to produce PDFs (I have not tried this in production but don't see why it wouldn't work).

Ask HN: Looking for lightweight personal blogging platform
Others have mentioned static site generators. I like Hakyll [1] because it can tightly integrate with Pandoc [2] and allows you to develop custom solutions if your needs ever grow.

Show HN: CLI for generating beautiful PDF for offline reading
Have you compared it with a conversion by pandoc (https://pandoc.org/)?

Pandoc
I have used it to kickstart a blogging project that I wish to come back to soon. The Lua inter-op for custom readers, writers and filters is great but I wish there was more editor integration and even perhaps an official IDE/editor with built-in debugging features (probably something already do-able with Emacs but I haven't checked). The only blocker for my project is no support for "ChunkedDoc" for Lua filters [1] which forces me to write more code and a complicated Makefile.
