Auto tiling is a powerful technique in 2D gamedev that allows you to build levels much easier by setting a tile as populated or not, and having the editor programmatically place the corresponding tile. Typically this involves checking the 8 … Read more
Bluetooth® audio has come a long way since 2001, when the Headset Profile (HSP) and Hands-Free Profile (HFP) first enabled bidirectional voice calls over Synchronous Connection-Oriented transport. The Advanced Audio Distribution Profile (A2DP) followed in 2003, bringing high-quality audio streaming … Read more
In this post, I’ll walk you through how to create a custom shader in Three.js that simulates the look of a foil sticker, complete with angle-dependent iridescence and sparkling metallic flakes. The goal is to capture that premium, holographic effect … Read more
I first ran into Forth about 20 years ago when reading a book about designing embedded hardware. The reason I got the book back then was to actually learn more about the HW aspects, so having skimmed the Forth chapter … Read more
Posted on December 27, 2021 by Thomas Mahler Abstract Implementing a small functional language with a classic combinator based graph-reduction machine in Haskell. The implementation is structured into three parts: A λ-calculus parser from A Combinatory Compiler which was extended … Read more
I’m continuing my work on fennel-cljlib, my port of clojure.core and some other core libraries, focusing on porting missing functions and features to it. One such feature, which I sometimes miss in Lua and Fennel, is dynamic binding. The Lua … Read more
In this article I want to document my journey implementing fast TCP fingerprinting in a golang webserver, using eBPF. Just to provide some background, TCP fingerprinting is one of the many techniques that can be used to detect unusual or … Read more
I just think it’s neat! Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three … Read more
Implementing DOES> in Forth, the entire reason I started this mess The issue I had with DOES> isn’t that it’s hard to use—it’s just that I had no idea how one would go about implementing it, much like Javascript programmers … Read more
To implement a seamless Linux integration into Starina, I decided to go with a Linux lightweight VM approach similar to WSL2. This means I need to implement a hypervisor that can run Linux. I had implemented an Intel VT-x based … Read more
