Kiln, the next iteration of Ethereum merge testnets, is now live 🔥🧱

Highly recommended that node operators, application developers, stakers, tooling/infra providers test their setups on the network. Blog post has all the info to get started 😁

Our greatest release ever!
- Generics
- Fuzzing
- Module workspaces
- debug/buildinfo (SBOM)
- net/netip
- ARM64 & PPC64 regabi (+15% performance)

I'm often asked how I approach, learn, and ultimately contribute to existing complex software projects. This applies to open source as well as non-OSS work. I decided to write and share my process for learning and contributing to complex projects: https://t.co/pkeqRWziFp

A surprising and undervalued aspect of mastery comes from narrow-scope "microskills". In software, these would be things like

- Python list comprehensions
- Grep flags
- Debugging specific error messages
- Using a window manager

We can, and should, do targeted training.

@harisamin Congratulations Haris! That's so exciting.

We’re doing some great work right now! It’s been super fun, challenging, and rewarding work. I couldn’t ask for better teammates! We’ve built a custom state of the art type checker, VM, and with some cool storage features all with some nice IDE/debugging tooling around it too!

[Larry Diehl @larrytheliquid]

Looking for lang engineer to join my team developing SymPL (https://t.co/p6nytf8HkA). Role focus is on the transpiler (from Python-like lang to ML-like core lang) and runtime, so needs strong Haskell eng experience but deep lang expertise not required. https://t.co/hUN8fVg6z1

[Javier Neira @jneira]

Contributing to open source is hard, take your time and sometimes is ungrateful but then you read comments like

about haskell-language-server

I'll try to be more thankful and let it know to the maintainers of my every day software.

[Csaba Hruska @csaba_hruska]

The external STG interpreter can run GHC now!
Finally it is possible to analyize what GHC does during compilation. Why does it takes so much time? Leaks? Sharing loss? I'd like to figure it out.

[Javier Neira @jneira]

haskell-language-server-0.9.0 has been released!

This release includes lot of refactorings and bug fixes over existing features, hlint and eval plugins among others.
It contains a fix for a bug in ghcide involving stale diagnostics

* It includes two brand new plugins: hlint support and module naming helper
* improvements and fixes for the tactic plugin
* it uses last ghcide-0.5.0

I'm very excited about #HaskellFoundation. Please attend this talk -- there will be *lots* of time for questions!

[Rahul Muttineni @rahulmutt]

Just tried out Intellij IDEA after a long time to see if it could be more responsive than VSCode on on my low-end machine. Not only is it snappy, it provides me with nice type information for a Java 8 stream chain! Great work @intellijidea team.

[Rahul Muttineni @rahulmutt]

Interesting take on building successful Haskell projects:

More secure and faster than Circe, ZIO JSON features powerful, compositional encoders and decoders, and blazing fast single-line derivation powered by Magnolia.

This is the JSON library you were always looking for. Now available via snapshot releases!

Can't sleep, who wants to hear about how high-performance interpreters store objects?

Basically they sneak data into unused bit-patterns in floating point numbers.

[David Barbour @awelonblue]

@jdegoes I don't always favor recursion in my PL designs. But when I do, tail recursion is a must.

An alternative is to develop a combinatory logic with a limited set of loop combinators - e.g. unfold/fold/traverse/zip/unzip. Simplifies provenance tracking, pipelining, and stream fusion.
