Go: The Good, the Bad and the Ugly
This is an additional post in the “Go is not good” series. Go does have some nice features, hence the “The Good” part in this post, but overall I find it cumbersome and painful to use when we go beyond API or network servers (which is what it was designed ...

Why Does “=” Mean Assignment?
Take the following code: a = 1 a = a + 1 print(a) A common FP critique of imperative programming goes like this: “How can a = a + 1? That’s like saying 1 = 2. Mutable assignment makes no sense.” This is a notation mismatch: “equals” should mean “equality”, when it really means “assign”. I agree with this criticism and…

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 .

Are unsound type systems wrong?
This is an essay I wrote early-2016. After battling with soundness vs. usability in Typed Clojure for many years, I was starting to reconsider the “obviously wrong” approach of baking unsoundness into the type system from the get-go. I look at some historical examples of intentional unsoundness in type systems, and…

A Virtual Machine
Magicians protect their secrets not because the secrets are large and important, but because they are so small and trivial. The wonderful effects created on stage are often the result of a secret so absurd that the magician would be embarrassed to admit that that was how it was done.

Deprecating Raw Pointers in C++20
The C++ Standard moves at a fast pace. Probably, not all developers caught up with C++11/14 yet and recently we got C++17. Now it’ time to prepare C++20! A few weeks ago The C++ Committee had an official ISO meeting in Jacksonville, FL (12-17 March 2018) where they worked hard on the new specification.

Gradual Programming
Programming is a fundamentally incremental (or gradual) process, and our programming languages should reflect that. I show several ways in which program models transition over time and discuss how future research can further a human-centric vision for programming languages.

Python Idioms in Rust
I’ve been going through a period of programming language wanderlust over the past couple months. Recently, I’ve been quite interested in Rust. Coming from Python, I’ve found a lot of Rust’s language features to be quite powerful.

How to Use Go Interfaces
I occasionally give free Go consults and code review on top of my daily work. As such, I tend to read a lot of other peoples’ codes. And while this is really more of a feeling *Now, you should go, really? You're a statistician by training ffs, I’ve seen an increase in what I call “Java-style” interface usage. This…
