We build a shell in the style of the Bourne shell, Bash, zsh, etc. It supports (1) running commands with arbitrarily many arguments, (2) quoting those arguments, and (3) combining the commands into arbitrarily long pipelines where the output of one command becomes the input of the next. This requires writing a parser…
In this post I discuss request smuggling, the recent vulnerability in ASP.NET Core with a severity score of 9.9, and how attackers could exploit it
The other day at work, we had a situation where we suspected a thread leak in one particular service, i.e. code which continuously starts new threads, without taking care of ever stopping them again. …
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.
TLA+ model checking made symbolic Konnov et al., OOPSLA’19 TLA+ is a formal specification language (Temporal Logic of Actions) particularly well suited to reasoning about distributed algorith…

Hard SF worldbuilding with the HYG database, Dijkstra's algorithm, and Lisp.
Update: We’ve won Node Knockout in the “Completeness” category ! Congrats to the team!
How to build a CLI coding agent
Sixteen years ago to the day, I started RailsCasts, a screencast series teaching web development using Ruby on Rails. It began with free weekly episodes…
This guide is mainly intended for expert programmers familiar with Java concurrency, but unfamiliar with the memory order modes available in JDK 9 provided by VarHandles. Mostly, it focuses on how to think about modes when developing parallel software. Feel free to first read the Summary .
It’s been roughly 3 years since DDraceNetwork (DDNet) started in the summer of 2013. Last year I wrote a non-technical History of DDNet . Today in this post we will dive into the technical side of what makes DDNet run.
How I rolled up my sleeves and got a real-time lighting engine working under the constraints of PICO-8.
🦑 Informal definitions of terms used in concurrency modeling
Another year, another year-in-review post. To be honest, I feel like any attempt I make to summarize what happened in the Clojure world this year is largely moot. Clojure has gotten so big, so — dare I say it? — mainstream that I can’t even begin to keep up with all the interesting things that are happening. But it’s…
The Elixir 1.12 version introduced some significant changes. The main one is the ability to create scripts and import dependencies via Mix.install. The interactive console can be more helpful in the software development, prototyping and debugging processes.
Concurrency Control is a mechanism that maintains atomicity and isolation, which are two properties of the ACID, when multiple transactions run concurrently in a database.
strlcpy(3) is an OpenBSD function which is often hailed as a safer replacement for strcpy(3) and/or strncpy(3) . One of the obvious issues with strlcpy is that it's not safe if src isn't null-terminated. However, that's not the reason I don't like strlcpy. In fact despite knowing this, I used to think it was an okay…
I really like C++. It's not the right tool for every job, but it's what I reach for when I need to do any kind of systems programming. Unfortunately, C++ has often been cited as a "bad" language, and I feel like that reputation has worsened over time. Recent languages like Go and Rust have taken over a lot of mind…
While all three remove boilerplate, the similarities don't go much further. Records have stronger semantics with important downstream benefits, which makes them better*. (* not always; depends on circumstances; excuse the clickbait)
In this post, I'll show you a common pitfall you should avoid when teaching during code reviews.
