Writing a Simple Garbage Collector in C (2014)
People seem to think that writing a garbage collector is really hard, a deep magic understood by a few great sages and Hans Boehm (et al) . Well it’s not. In fact, it’s rather straight forward. I claim that the hardest part in writing a GC is writing the memory allocator, which is as hard to write as it is to look up…

C Strings and my slow descent to madness
I’ve been on a C kick recently as I learn the intricacies involved in low level programming. As a Data Scientist/Python Programmer I work with strings all the time. People say that handling strings in C range anywhere from tricky to downright awful. I was curious so I decided to see how deep the rabbit hole went.

Simply explained: How does GPT work?
By now, you have probably heard of OpenAI’s ChatGPT, or any of the alternatives GPT-3, GPT-4, Microsoft’s Bing Chat, Facebook’s LLaMa or even Google’s Bard. They are artificial intelligence programs that can participate in a conversation. Impressively smart, they can easily be mistaken for humans, and are skilled in a…

MutexProtected: A C++ Pattern for Easier Concurrency
In this post, we will discuss the challenges of programming with locks and how the C++ language offers some useful tools to make it easier. We will start with an example in C and then use C++ to improve upon it in steps. The example APIs are based on real-life APIs from the SerenityOS kernel.

The real “must have” tools for programming
Forget programs. The most important productivity tool for programming is your mind. And the next best set of software development tools are ones that take care of you. It isn’t about Git. Or Docker. Or testing frameworks. These are all useful tools. I use them daily. But they are not the most important software…

Calling Purgatory from Heaven: Binding to Rust in Haskell
Calling hell from heaven and heaven from hell is a classic paper from the previous century, introducing the Haskell foreign function interface (FFI). It describes the facilities that Haskell offers for calling functions written in C (and vice versa). In this blog post, we will consider how to call functions written in…
