Borrow checking without lifetimes
This blog post explores an alternative formulation of Rust’s type system that eschews lifetimes in favor of places . The TL;DR is that instead of having 'a represent a lifetime in the code, it can represent a set of loans , like shared(a.b.c) or mut(x) . If this sounds familiar, it should, it’s the basis for polonius…

Recursion, continuations and trampolines (2017)
How is tail recursion different from regular recursion? What do continuations have to do with this, what is CPS, and how do trampolines help? This article provides an introduction, with code samples in Python and Clojure.

How GCC and Clang handle statically known undefined behaviour
Recently, we had a discussion in our team about undefined behaviour (UB) in C. For those unfamiliar: We say that a program has undefined behaviour when we write code where the language specification doesn't define what should happen during execution. That means compilers can do whatever they like if they encounter…

Needle: A DFA Based Regex Library That Compiles to JVM ByteCode
Many years ago, Kragen complained about the implementation and performance of Java regexes , and suggested that an implementation that emitted JVM bytecode could perform better. It's been a minute, but I'm happy to report that complaining on the Internet has served its purpose.

Design Patterns Are Temporary, Language Features Are Forever
Design patterns are these cool things that make you go 'hell yeah' because they make a certain problem easier to deal with. Whether it's applicable to all languages, or due to a language constraint, they're pretty nice. Of course, some people go crazy with them rather than doing the simple thing that works. Other…

Generalizing Support for Functional OOP in R
R has built-in support for two functional Object Oriented Programming (OOP) systems: S3 and S4, corresponding to the third and fourth version of the S language, respectively. The two systems are largely compatible; however, they are two fundamentally distinct systems, two systems for a user to understand, two systems…

Algebraic effects, ownership, and borrowing
Algebraic Effects are a useful abstraction for reasoning about effectful programs by letting us leave the interpretation of these effects to callers. However, most existing literature discusses these in the context of a pure functional language with pervasive sharing of values. What restrictions would we need to…

Performance Analysis of Python's Dict() and {}
Some time ago, during a code review, I had a discussion with a colleague of mine about preferring dict() over {} in new Python code. They argued that dict() is more readable — and expresses intent more clearly — therefore should be preferred. I wasn’t convinced by that, but at that time I didn’t have any…
