ghc-debug is a debugging tool for performing precise heap analysis of Haskell programs (check out our previous post introducing it). While working on Eras Profiling, we took the opportunity to make some much needed improvements and quality of life fixes to both the ghc-debug library and the...
I've mentioned my new effect system, Bluefin, a few times on this forum. It's now ready for me to announce it more formally....

This is the first of a two-part series of blog posts on GHC specialization, an optimization technique used by GHC to eliminate the performance overhead of ad-hoc polymorphism and enable other powerful optimizations. There will also be a Haskell Unfolder episode about this topic.
This fuses:...

When composing several list-processing functions, GHC employs an optimisation called foldr-build fusion. Fusion combines functions in such a way that any intermediate lists can often be eliminated completely. In this episode, we will look at how this optimisation works, and at how it is implemented in GHC: not as built-in...
In this episode, András Kovács is being interviewed by Andres Löh and Matthias Pall Gissurarson. We learn how to go from economics to functional programming, how GHC's runtime system is superior to Rust's, the importance of looking at GHC's Core for spotting stray closures, and why staging might be the answer to all your...

The best case scenario when testing a piece of software is when we have a reference implementation to compare against. Often however such a reference is not available, begging the question how to test a function if we cannot verify what that function computes exactly. In this episode we will consider how to define properties to...
In this two-day event, held on the lakeside campus of OST in lovely Rapperswil, Switzerland, you can learn what you need to know in order to get started working on these tools. We’ve asked the presenters to identify ‘good first issues’ for those wanting to get their feet wet on contributing. Because the workshop is...
Wouter and Niki interview Jose Calderon, the new Executive Director of the Haskell Foundation. Jose tells why he applied for the job, how he sees the foundation developing over the coming years, and how you can get involved in the Haskell community.
