IIR filters can be evaluated in parallel | Raph Levien’s blog
Noting that expressing them in matrix form is better than direct form, and then shows lifting them into a monoid representation: "this works because the function is linear"
(There's still a lot of math in here and I probably need a second reading to grasp it)

Functional Languages for Real-Time Control
"Much of my research has been the development of functional languages with temporal semantics. The first of these was Arctic, which was the purest, but least practical language. Canon applied Arctic ideas to generating MIDI scores and use Lisp as a foundation. Fugue extended Canon to manipulate digital audio, and Nyquist is a reimplementation of Fugue making more extensive use of lazy evaluation of signals."

Luna
"built on a principle that people should not be limited by the tool they use. It was designed as a general purpose programming language with two equivalent representations – visual and textual. The graphs are as powerful as the code and Luna lets you switch between them at will."

in which the cost of structured data is reduced - Technomancy
"Often times the trade-off between freeform maps/hashes vs structured data feels like one of convenience vs long-term maintainability. While it's unfortunate that they can't be used with the xml structs4, lenses provide a way to get the best of both worlds, at least in some situations."

F*: A Higher-Order Effectful Language Designed for Program Verification
"an ML-like functional programming language aimed at program verification. Its type system includes polymorphism, dependent types, monadic effects, refinement types, and a weakest precondition calculus. Together, these features allow expressing precise and compact specifications for programs, including functional correctness and security properties. The F* type-checker aims to prove that programs meet their specifications using a combination of SMT solving and manual proofs. Programs written in F* can be translated to OCaml, F#, or C for execution. "
(used in the HaCL* verified crypto library)

Selling Monads
Quoting an HN comment that answers in a nice language-agnostic way why monads are useful, and noting that explanations should come before dragging the conversation into "all about Haskell/Scala":
"So yes, it’s true that Monad allows us to sequence effects in a lazy pure language, and that’s important, but I think a more down to earth reason to be interested is that it allows for more code reuse"

Finger Trees: A Simple General-purpose Data Structure
"a functional representation of persistent sequences supporting access to the ends in amortized constant time, and concatenation and splitting in time logarithmic in the size of the smaller piece. Representations achieving these bounds have appeared previously, but 2-3 finger trees are much simpler, as are the operations on them. Further, by defining the split operation in a general form, we obtain a general purpose data structure that can serve as a sequence, priority queue, search tree, priority search queue and more."

stedolan/malfunction
"a high-performance, low-level untyped program representation, designed as a target for compilers of functional programming languages.[...] a revolting hack, exposing bits of the OCaml compiler's guts that were never meant to see the light of day."

Functional Programming, Abstraction, and Names
"Programming with precise algebraic names and equational reasoning is here to stay, and the edifice of abstraction is only going to grow as programming becomes more precise and refined."
@tel: "This should be ground reading for anyone who wishes to engage in conversation about the names of Haskell abstractions or the decision to write a “monad tutorial”."

The Ur Programming Language Family
"a programming language in the tradition of ML and Haskell, but featuring a significantly richer type system. [...] Ur/Web is Ur plus a special standard library and associated rules for parsing and optimization. Ur/Web supports construction of dynamic web applications backed by SQL databases. The signature of the standard library is such that well-typed Ur/Web programs "don't go wrong" in a very broad sense."

Two views of programming language design | The Lab Lunch
"To summarise, the axiomatic approach views the underlying lambda calculus simply as middleware for hooking arbitrary stuff together, whereas the type-theoretic approach sees the (appropriately enhanced) lambda calculus as a proper programming language. Fortunately the two approaches are not incompatible, because there is nothing stopping us from postulating axioms in a type theory. It may be considered in questionable taste, but it can be helpful!"

CiteSeerX — Out of the Tar Pit
Is this the first FRP paper? Synthesizes FRP after examining OO and functional programming, then combining the ideas with logic programming and Codd's relational algebra.
"We have argued that complexity causes more problems in large software systems than anything else. We have also argued that it can be tamed — but only through a concerted effort to avoid it where possible, and to separate it where not. Specifically we have argued that a system can usefully be separated into three main parts: the essential state, the essential logic, and the accidental state and control."

A Taste of the Star Programming Language - Squid's Blog
"Star is a coherent, general-purpose programming language that combines elements from a wide variety of existing languages as well as adding innovative elements of its own. Star inherits functional programming in general, a Haskell-style type system, an F#-style monad for parallel computations, and Concurrent ML for orchestrating concurrent and parallel applications."
