Embracing Flexibility in Haskell Libraries: The Power of Records of Functions
Improve the robustness and flexibility of your Haskell apps by changing how you design your libraries.
Hi, Barbie! Higher kinded records made easy(er)
We often need to make and manipulate derived types that are similar to each other, but not quite the same. Higher-kinded records provide a way to do this in a generic way, but are clunky. We\
Haskell Best Practices– Wildcards aren\
An argument for using really exhaustive pattern matching.
There and Back Again: Turning Haskell functions into RPC calls- Part 2
In the last post, we figured out an interface for the RPC caller to invoke remote Haskell functions. In this post, we\

Integrating a large Tokio-based Rust library with Haskell
A lot of the Rust <-> Haskell interop examples out there are for small, synchronous libraries. They also tend to omit how to actually package the Rust library. We\
One Serialization Class to Rule Them All
Typical serialization libraries in the Haskell ecosystem target a single format. We explore how to provide composite serialization for data types that chooses the best format for each data type.
OpenTelemetry Gotchas– Phantom Spans
We struggled for several months with a mysterious tracing issue in our production environment. Unrelated web requests were being linked together in the same trace, but we could never see the root trace span. This is the story of how we found and fixed root cause.
