Replacing my Octopress blog with 200 lines of Babashka
Seven years ago I started writing about my adventures with Clojure. I started using Octopress back then and was still using it until today. Octopress worked great for my blogging purposes and I'm grateful that it existed. However, in recent years I became frustrated with the experience of using it, which is probably…

Understanding x86_64 Paging
I’ve spent quite a lot of time messing with x86_64 page tables, understanding address translation is not easy and when I started learning about it I felt like a lot of the material out there on how it works was hard for me to wrap my head around.

Micro C, Part 3: Generating LLVM
In part 2, we completed the user facing part of the compiler with semantic analysis. Now we're free to focus on the backend, generating LLVM. To do so, we'll use the llvm-hs-pure library, which embeds LLVM into a Haskell ADT, allowing us to manipulate it without having to set up any FFI.|A blog about various…

But mostly I love C because when I write C I feel an intimate connection with my computer. To me, C has soul. In fact all my personal project are written in C, like the graphics rendering engines that I'm…

Configuration files are user interfaces
We have all been there. Your software keeps growing and you feel the need to make it customizable. It is too soon for a full-blown UI with all the bells and whistles, so your pragmatic instinct suggests a text-based configuration file. Yes, that’s exactly it!
