In this brief post I want to discuss a fairly unusual feature of Haskell - functions that can be parameterized by their return type.

Classification of the Principal Programming Paradigms (2009)
The chart classifies programming paradigms according to their kernel languages. Kernel languages are ordered according to the creative extension principle: a new concept is added when it cannot be encoded with only local transformations. Two languages that implement the same paradigm can nevertheless have very…

The Elixir of concurrency
Elixir is a fairly young language that was born when José and a few Rails developers tried to create a modern language optimized for concurrent, distributed, lightweight processes They wanted a modern Ruby-like syntax with a well-tested process ma

Avoiding Reflection (And Such) in Go
So, as previous posts show , I like Go well enough. But as a computer-language polyglot, "Go programmer" is not part of my identity, and I try for a balanced view. It is very human to go overboard in both praise and criticism, both easy to find online.

Threads (in Ruby): Enough Already
For a while now, the Ruby community has become enamored in the latest new hotness, evented programming and Node.js. It's gone so far that I've heard a number of prominent Rubyists saying that JavaScript and Node.js are the only sane way to handle a number of

Resurrecting Fortran
We have finished the first chapter on a long journey of resurrecting Fortran: forming an initial core community of developers and users with enough momentum around the new Fortran website and projects at fortran-lang.org . There is still have a long way to go to, but this was a necessary (although not sufficient)…

Why the Sorbet type checker is fast
This is the second in an indefinite series of posts about things that I think went well in the Sorbet project. The previous one covered our testing approach. Sorbet is fast. Numerous of our early users commented specifically on how fast it was, and how much they appreciated this speed. Our informal benchmarks on…

Revisiting 'Monadic Parsing in Haskell'
‘Monadic Parsing in Haskell’ is a short paper that laid the groundwork for libraries like Parsec and Attoparsec. Although it was published in 1998 (almost 20 years ago!) it has aged gracefully and the code samples will run with almost no changes. However, the state of the art has advanced since then and I think the…

They Called It LISP for a Reason: List Processing (2005)
Lists play an important role in Lisp--for reasons both historical and practical. Historically, lists were Lisp's original composite data type, though it has been decades since they were its only such data type. These days, a Common Lisp programmer is as likely to use a vector, a hash table, or a user-defined class or…
