Typestates in Rust (2018)
A long time ago, the Rust language was a language with typestate. Officially, typestates were dropped long before Rust 1.0. In this entry, I’ll get you in on the worst kept secret of the Rust community: Rust still has typestates.

80x25
Every now and then, my brain clamps on to obscure trivia like this. It takes so much time. “Because the paper beds of banknote presses in 1860 were 14.5 inches by 16.5 inches, a movie industry cartel set a standard for theater projectors based on silent film, and two kilobytes is two kilobytes” is as far back as I…

Introduction to Datalog
In contrast to the imperative programming paradigm, declarative programming expresses the logic of a computation without explicitly specifying its control flow. That is, declarative programming focuses on the what , not the how . If you have tentatively researched declarative programming before, you have likely read…

A proof that Unix utility sed is Turing complete
Many people are surprised to learn that `sed`, a seemingly simple text filtering program, is actually Turing complete. This realization prompts the question: how can a text processing utility achieve such computational power? The answer lies in sed's fundamental operations. Essentially, sed functions as a miniature...

What senior engineers do: fix knowledge holes
I had a bad week a few weeks back, and got together with a friend and former colleague. We started trading war stories. He mentioned one time when he was working for a company which had both a desktop client and a server component. The communication between the two pieces of the system was completely, utterly…

Perils of Constructors
One of my favorite blog posts about Rust is Things Rust Shipped Without by Graydon Hoare. To me, footguns that don't exist in a language are usually more important than expressiveness. In this slightly philosophical essay, I want to tell about a missing Rust feature I especially like: constructors.

It is perfectly OK to only code at work, you can have a life too
There is often pressure inside Software development for Software developers to code outside of work hours. Whether you are a Python, Ruby, Java, or any other developer... There is absolutely no need to code outside of work if you don't want too. Coding is considered a passion for some, but others they don't think this…

A Go implementation of Poly1305 that makes sense
Cryptography code could be understandable if only we commented it. This Poly1305 implementation is an attempt to prove it. It should be readable with just an idea of what MACs are for, a beginner level of Go, and high school math.
