Show HN: Tinyhnsw – The Littlest Vector Database (github.com/jbarrow)
TinyHNSW is a tiny, simple vector database. It weighs in at a measly few hundred lines of code. It's built on a straightforward (but not fast) implementation of HNSW in Python with minimal dependencies. It has an associated set of tutorials that build up to understanding how HNSW works, and how you can build your own TinyHNSW.

Ray Tracing in One Weekend (raytracing.github.io)
I’ve taught many graphics classes over the years. Often I do them in ray tracing, because you are forced to write all the code, but you can still get cool images with no API. I decided to adapt my course notes into a how-to, to get you to a cool program as quickly as possible. It will not be a full-featured ray tracer, but it does have the indirect lighting which has made ray tracing a staple in movies.

Write a Shell in C (2015) (brennan.io)
It’s easy to view yourself as “not a real programmer.” There are programs out there that everyone uses, and it’s easy to put their developers on a pedestal. Although developing large software projects isn’t easy, many times the basic idea of that software is quite simple. Implementing it yourself is a fun way to show that you have what it takes to be a real programmer.

Self-Hosting a VPN with Tailscale on a Raspberry Pi (github.com/johnnyfivepi)
Inspired by my admiration for Tailscale and their innovative, open-source approach to networking, I decided to challenge myself by setting up a VPN on my Raspberry Pi. Along the way, I also wanted to create a walkthrough that anyone could follow, whether they're just starting out or have more experience. The result? A detailed guide to configuring Tailscale on a Raspberry Pi, from flashing the microSD card to setting up an exit node.

Software-defined (Internet) radio with Liquidsoap (2023) (yossarian.net)
This is going to be another short “how-to” blog post on music management, this time on declarative Internet radio streaming with Liquidsoap. I couldn’t find a ton of great examples of Liquidsoap online while defining my own radio stream (besides the project’s own excellent docs), so I figured I’d write one.

Making Of: Line Drawing Tutorial (2017) (redblobgames.com)
People ask me how I write my interactive tutorials. I can point at the HTML+CSS+JS but that doesn’t show the process. On this page I’ll recreate the first half of my line drawing tutorial[1], showing the an implementation using D3.js v4[2]. The implementation style will be similar if you use jQuery. I also have another page showing an implementation using the Vue/React/Svelte declarative style[3].
