If you start learning about functional programming, it won’t be long before you come across the idea of pure functions. And as you go on, you will discover functional programmers appear to be obsessed with them. “Pure functions let you reason about your code,” they say. “Pure functions are less likely to start a…

Memory-Level Parallelism: Intel Skylake versus Apple A12/A12X
Modern processors execute instructions in parallel in many different ways: multi-core parallelism is just one of them.

Writing a recursive ascent parser by hand
I’ve been exploring various ways to write parsers. For a long time, I’ve used hand-written recursive descent for its straightforwardness, flexibility, and performance. There is another way—parser generators like Menhir , LALRPOP , or the venerable Bison use the bottom-up LR algorithm .

Typesafe Neural Networks in Haskell with Dependent Types
It seems these days like programming with dependent types in Haskell (and its advantages) is moving slowly but steadily to the mainstream of Haskell programming. In the current state of Haskell education, dependent types are often considered topics for “advanced” Haskell users. However, I can foresee a day where the…

Most strings found on the Internet are encoded using a particular unicode format called UTF-8. However, not all strings of bytes are valid UTF-8. The rules as to what constitute a valid UTF-8 string are somewhat arcane. Yet it seems important to quickly validate these strings before you consume them. In a previous…
